The material created in China that lowers the temperature of the buildings without consuming a single electricity watt

by

A world where buildings are not only well isolated from abroad, but cool them as much as an air conditioning, without consuming a single electricity watt. That is what a team of Chinese and Australian scientists promises with their new bioplastic material. Short. Researchers at the University of Zhengzhou and the University of Australia del Sur presented a biodegradable film capable of cooling buildings without using electricity. According to a study published in Cell Reports Physical Sciencethis coating can reduce the temperature of a surface to 9.2 ° C in full sun. 9 degrees less. In the material field tests, carried out on a Zhengzhou roof, east of China, the results were overwhelming. In full sun, during noon, the material reached a cooling peak of 9.2 ° C below the ambient temperature. The average tests was -4.9 ° C during the day and -5.1 ° C during the night, which is equivalent to a cooling power of up to 136 watts per square meter. The film takes advantage of a known phenomenon, “passive radiative cooling” (PRC). In a nutshell, it is a lining designed to do two things: reflect sunlight so as not to heat up, and emit internal heat outwards. But it does it in an extremely efficient way. According to the simulations presented by the researchers, apply this film on the roofs of a city like Lhasa, in the Tibet, would reduce annual cooling consumption up to 20.3%. How it works. The “metaphilm” is made of polyactic acid, better known as Pla plastic; A material derived from plant sources such as corn or sugarcane, so it is biodegradable. The turn is how researchers managed to create a porous and continuous structure through a novel phase separation technique at low temperature. This microstructure has an ultrabaja thermal conductivity (of 0.049 w/m · k) and reflects almost all the solar radiation that affects it (98.7%), avoiding the initial heating and heat transfer to the interior. It also emits heat abroad thanks to its porosity. The manufacturing process is relatively simple: the PL is dissolved in chloroform, crystallizes at -20 ° C and then ethanol is used to induce phase separation before drying the film. This method is suitable for large -scale production, which paves the path for commercialization. More resistant than other attempts. One of the great challenges of previous radiative cooling materialsespecially biodegradables, it was their durability. But this new coating has demonstrated exceptional durability. The researchers submerged him in acid for 120 hours and then exposed him to ultraviolet radiation equivalent to eight months of weathering exposure. Surprisingly, the material not only survived, but maintained a cooling performance between 5 ° C and 6.5 ° C below the ambient temperature after the hard aging process. The team attributes it to its high crystallinity, which gives it a thermal and chemical stability much higher than that of its predecessors. The applications go far beyond the roofs of the buildings. Researchers already explore their use in transport, to cool vehicles, agriculture, to protect crops, electronics and even the biomedical field, to apply to dressings that regulate the temperature.

This city of China is the world epicenter of rare earths. The problem is that nobody thought of its inhabitants

by

To get an idea to what extent It has control Of those precious minerals that form the set of rare earths, the greatest enemy that China has is not outside its borders. It is such a monopolization in the sector that the danger has in “house” through of the smugglers. And of all enclaves, one stands out greatly as an epicenter of the entire heart. His name is Baotou, and everything that shines for the surrounding inhabitants is not gold. A normal city in appearance. Baotouan industrial core of 2.7 million inhabitants on the border with the Gobi desert, seems to the naked eye a second category Chinese city like so many others: shopping centers with western chains, local restaurants overflowing and children playing late. However, a short journey to the outskirts is enough to discover His true nature: A landscape dominated by factories, smoking chimneys and an environmental legacy forged by one of the most strategic and persecuted sectors of the planet. The heart of rare earths. Yes, the enclave houses More than 80% of the Rare reserves of China. Since in the 30s they were discovered in the nearby Mining District of Bayan Obo elements such as Cerio, Lantano or Samario, its exploitation has turned the city on a chain axis on global supply on industries such as electronics, automotive and defense. We have counted before: During the 90s, China increased its production by 450%, while other countries, such as the United States, They closed their mines. This concentration made Beijin the almost exclusive supplier of these critical metals, and today, in the midst of the commercial war with Washington, its control has been transformed In diplomatic weapon. Economy vs Human Cost. The problem? The Guardian told that mineral wealth has favored the economic development of Baotou, whose GDP per capita It widely exceeds the national average. However, prosperity has Your reverse: Processing plants generate toxic (often radioactive) waste that are discharged into huge artificial rafts. The most infamous, the Weikuang dam, for years was the largest landfill of rare earth waste on the planet, without adequate coating and directly close to the Yellow River. In fact, official reports have confirmed that these activities caused a 87% decrease of ammoniacal nitrogen in a tributary between 2020 and 2024, although accumulated ravages remain visible. Yin mountains on the outskirts Cancer and poison. For example, numerous studies They have documented devastating consequences in the health of nearby communities: from bone malformations to a “Epidemic” of cancer. Exposure to these elements, capable of crossing the blood brain barrier, has been associated with motor and sensory disabilities, as well as alterations in fetal neurological development. Not just that. 2020 investigations revealed that the dust of the streets contains concentrations so high that the children of Baotou and surroundings are exposed to dangerous levels Just to breathe. Daily particle ingestion rates in mining areas far exceed the limits considered safe. A washing … halfway. Given the growing international criticism, China has tried to clean its image. In 2022, state media announced that Weikuang’s dam had been transformed into an urban wetland, now supposed paradise of migratory birds. The reality? Explained the medium British that when arriving at the place, what one is located is a concrete wall that hides a dry and desolate lodazal. Behind, ruins of ancient “villages of cancer” and oxidized industrial structures extend. New homes built for displaced are practically empty, and foreign journalists are It usually blocks actively to prevent them from talking to residents. Rural sacrifice. So things, Baotou exemplifies an uncomfortable truth: the China domain In the rare earth market it has been possible not only for its geological reserves, but for a political decision where rural communities have been allowed to support Toxic costs of a globalized economic boom. It is not an exempt problem from China, of course, the same thing happens in other sectors such as AI and its data centers (we recently counted it with the Elon Musk Supercomputer). Be that as it may, and although there are less polluting technologies to process these metals, they are rarely used: its implementation would make the low costs that have cemented the Chinese position. If you want, in a context of growing international pressure and commercial sanctions, the extractive model It reveals both the fragility of environmental balance and the rawness of contemporary geostrategic priorities.

If we want to know what the end of cash will be like, we just have to look at a country that is living it: China

by

If you go to China and enter a trade, the most normal thing is that you cannot pay with cash. The blue and green logos of Alipay (Ant Group) and Wechat Pay (Tencent) dominate everything, and have been relegating to traditional coins and bills to an absolute background. While in the West we discuss what to do With cash And Europe considers What will happen to the digital euroIn China they are clear. Cash, nothing. Supermarkets, coffees, taxis, or public transport are some of the many types of scenarios in which The Chinese already pay with Alipay or Wechat Pay. At any point where it is necessary to pay the blue and green logos of these applications, everything dominate, and in fact many businesses do not even have a cash register. According to Le Mondemany taxis and local businesses refuse to accept cash payments, and if they accept them, they do not even have change for buyers. Source: Wikimedia Only the elderly pay with tickets. Ma Dian, a Hubei fruits and vegetable seller, commented in this newspaper how the disappearance of cash payments has lived. “I only accept effective to help the elderly. Below the 80s, practically everyone has made the change. Above, it is much more difficult to adapt.” The elderly are here the greats harmed, and they must ask their relatives for help from the difficulty that they propose to make mobile payments with Alipay or Wechat Pay. QR codes everywhere. The QR codes that we usually see in restaurants in Spain to consult the letter dominate everything in China. There the shops have static or dynamic codes (on screens such as TPV) that customers scan. If we are facing a static code, the client usually has to introduce the amount to be paid. In dynamic codes, the amount is automatically shown. The last step is to authenticate with a password, facial recognition or a fingerprint. Although initially Alipay and Wechat Pay used different codes, in some cases unified QR codes are already used for both apps and it is the client who chooses with which app works on his mobile. Banks lose relevance. The absolute presence of these two digital payment systems have caused Chinese banks – government supplies – also have a secondary role for many clients. It is necessary to have a bank account to have it linked to these applications, but its mobile applications and services are totally overshadowed by Alipay and Wechat Pay, with which users do it practically everything in the field of payments and economic transactions. As John Engen said In American Bankerbanks are often reduced to “passive actors.” Powerful, but at bay. Although both Alibaba and Tencent have managed to monopolize these transactions, the Chinese government It has already demonstrated that remain entities that can be punished in a wrecking way. It happened in 2020 when Ant Group He was about From going to heel. Jack Ma criticized his government at that time, which caused The cancellation of that IPO and An exile of years for one of the great figures of entrepreneurship in China. China wants its digital renminbi. The Chinese Central Bank has been looking for a digital currency for years. Your digital renminbi or Yuan Digital You are also getting more than being an alternative to the dollar: is creating a parallel system. The objective is to have an alternative to the popularity of cryptocurrencies, but a controlled by the Chinese authorities. Although the deployment of this digital currency has been in progress for years, its prominence is very limited, and Momne both Alipay and Wechat Pay continue to dominate everything. And tourists, what. Both platforms, which before They made it difficult To tourists, they have progressively adapted to their needs. For approximately two years both Alipay and Wechat Pay allow foreign visitors to create an account in these applications and associate it with a credit card. Last year too They increased The transaction limits, which in Alipay went from $ 1,000 to 5,000, for example. Better with Chinese mobile number. In Wechat Pay it is even possible to access a kind of purse that they can fill in so as not to associate your Credit card to the app, and thus make small payments. It is necessary to have Internet access for these payments, and hire a SIM or a local ESIM to get a Chinese number – for example, for Validations with SMS – is especially recommended to facilitate this type of transactions.

China wanted to be the queen of high -speed trains. So he built all the longest bridges in the world

by

Although Arab Emirates and Saudi Arabia are immersed in a war for have the highest skyscrapers in the worldwhen we talk about megaconstructions, there is no one to have China. It doesn’t matter if we talk about tunnels, Dams, roads and even half -skyscraper. And, when we talk about bridges, there yes There is no rival. From time to time They complete a new pharaonic bridgebut if there is something that shows China’s muscle about it, they are the bridges of the Beijing-Shanghái line. Because it is in it where the three longest bridges are located in the world. Massive and … boring? He Great Danyang-Kunshan bridge It is the longest bridge in the world. It measures just over 164 kilometers and can also be the most boring bridge in the world. The reason is that it is a bridge in which functionality prevailed. It is part of the high -speed network that joins Beijing and Shanghai and in its construction, 10,000 workers used 450,000 tons of steel and 2.3 million m3 of concrete to give life to a structure that had to endure possible ships of ships and the impact of earthquakes. It has 2,000 pillars, 22 tunnels, it has an average altitude of just over 30 meters and trains circulate at a speed of more than 320 km/h. Declaration of intentions. The most striking thing is that it only took four years to complete the work. It is an achievement if we consider that other bridges, such as the Constitution of Cádizthey took more than seven years for about three kilometers. They began in 2006 and the works were completed in 2010, inaugurating both the bridge and the line in 2011. The investment? 8,500 million dollars, and although in later bridges we have seen an aesthetic intention by the engineers, that of Danyang-Kunshan was a declaration of intentions. It became a global reference in rail engineering, but above all in a sample of the Technological advance of the country when undertaking the Infrastructure construction large scale in record time. It is something that has also attracted attention to subsequent works, the speed at which things do, especially, in many occasions of works of great complexity. In dark red, the bridge. In clear red, part of the full line Beijing-Shanghai, a monster. Because although this bridge Have the Guiness record in length and it was an important technical advance, the most imposing thing is that it is only a piece of the puzzle that supposes the high -speed line Between Beijing and Shanghai. It is a connection with a length of 1,318 kilometers and, apart from that of Danyang-Kunshan, there are three other bridges that are on the list of the 10 longest in the world. He Great Bridge of Cangde measures 115.9 kilometers and the Great Tianjin Bridge It “stays” at 113.7 kilometers. The three are the longest in the world, and in the seventh place on the list is the Great Bridge of Beijingwith 48.2 kilometers. The four were completed for the inauguration of the line in 2011, assuming a pharaonic work and, in total, representing a third of the total line length. The artificial island of the Hong-Kong-Zhuhai-Macao bridge, which is a bridge over the water until it becomes a submarine “bridge” It is called obsession. Because, if we look at the list of the longest trains in the world, China is a constant, monopolizing with eight structures the top ten positions. Not only are they very long bridges to house train lines (the Weinan Weije It has 102.7 kilometers, but it is not from the Beijing-Shanghai line), also for roads. The fifth longest bridge in the world is Hong-Kong-Zhuhai-Macaohe longest maritime bridge With 55 kilometers (and, this yes, quite attractive), the eighth of the list is the Quingdao Haiwanwith another 44.5 kilometers of road and the tenth is the bridge of line 1 of the Wuhan Metro with 37.7 kilometers. Within those positions of honor, we only find a 54 -kilometer Thai bridge, the Band Na Expresswayand the Lake Pontchartrain Road in the United States with 38.4 kilometers.

China already has an army of drones and firefighters. And fight the fire to cannon

by

In recent days, a video has gone viral in Chinese networks: that of a skyscraper 150 meters with flames at the top. The special thing is that, fighting the flames there were no human firefighters, but drones. And, however futuristic it is, the craziest thing is that those drones are not alone: ​​next to you there are dogs, Robot dogs that have already been incorporated into the Fire Department. Fire drones. Fire can appear at any time. In Spain we know well, especially in summerand fighting it is dangerous for specialists. A way to give a first response to fire is Through robots and drones. But apart from being able to fight the fire without putting us at risk, the advantage is that they can reach high points to which a human would take longer to access. That’s why being able to fly, basically. In the video that we leave on these lines we can see some maneuvers in which two strategies against fire are raised. One is the most striking: robots that, armed with hoses, expel water and foam to placate the flames that appear abroad. As we say, it is something we carry years Seeing in different maneuvers in China. Fighting the fire to missile. Thus, there are several drones that can already rise to 200 meters and start fighting the flames in less than 30 seconds. It is a figure that a human cannot match and that gives time to land equipment to address the entrance to the building and rescue work. One of those models is the HZH CF30a drone with six blades capable of loading up to 30 kilos of weight and that has an interesting feature: it can be equipped with a multitude of tools, from emergency equipment for survival work to missile pitchers that are thrown into the interior to placate the flames from within. EHANG 216F. But there are also manned vehicles. An example is the EHANG 216-Fsimilar to the one that has already completed Test flights for the National Police of Spainbut focused on tasks of extinction and fire assessment in upper skyscrapers. With 16 propellers, an electric motor per propeller, a maximum speed of 130 km/Hy a flight time of 21 minutes, firefighters can use it in two ways. One, as an identification vehicle. Thanks to the camera and sensors like lidarThey can identify the location of the most critical points to act. The second, as a direct action vehicle thanks to its pressurized nozzle to expel fire extinction fluid and its six projectiles full of dry dust superfine. The payload they can transport is 220 kilos and the idea is that the cities fire stations can respond to fires in high -rise buildings that are within a three -kilometer radius with respect to the station itself. Special Unitree B2. Beyond the autonomous and manned drones, another recent added to the Fire Response forces are the United Square robots. Yes, the New Chinese technological jewel that has put to fight to two of his robots. A few weeks ago, They announced A version of your UNITREE B2 Designed for emergencies in dangerous environments. It is a modular robot that can be used within flames buildings to locate the focus, evaluate the level of gases or, directly, use a water and foam cannon that can be coupled to the spine. This model is reinforced with more resistant joints that help greater security when the robot is move through complicated landsuch as stairs or collapsed buildings. As we say, it has several modules that can be installed, being one of them a kind of “shield” that expels water not to turn off the fire, but to prevent the robot from overheating and can, thus, continue to operate in complicated conditions with fire. Rescue robots. And that there is so much device focused on rescue and emergency work in China is not a coincidence. It is something that is being promoted from companies and Governmentas demonstrates the recent International Emergency Exhibition of the Yangtze River Delta. Although it seems a specific name, the Expo has become a meeting point in which innovations are shown in the field of security, rescue work and disaster prevention. 500 companies from 20 countries gathered to show their technology, being models such as that of Unitree some of the main dishes of the event. Because, in the end, China is not alone in this. Japan already has its “Dragon firefighter”To combat the fire and we are clear that they can also be Help in natural disastersas forest fires.

China has won the data war without stealing any. We have given them to them

by

Despite the bodies that are usually tried to attribute in that sense, at least much more disproportionately than on the other side of the Pacific, China has not needed to steal secrets or technological secrets of the West. We have given them to them in a silver tray. Why is it important. There are several cases that do not mean much but united form a puzzle. For example, Apple and Its accumulated investment of 55,000 million dollars in China to “form” in advanced manufacturing. Or bytedance accumulating billions of hours of video labeling – and western– To train the most sophisticated recommendation algorithm we know. And now Apple can repeat the pattern with AI. The context. The dominant narrative points to Chinese industrial espionage as a cause of its technological boom. It is not so simple: Western companies have been the greatest facilitators of technological transfer in modern history, and did it voluntarily. The promise in return: margins. In the short term. The panoramic. Apple was one of the great responsible for China’s change, which went from manufacturer Low Cost A superpower of manufacturing in just two decades. Bytedance has converted western behavior data – hours and hours deciding what we like and what is not based on Scroll– In algorithmic supremacy for a five years. Tesla accelerated the Chinese ecosystem of electric vehicles and now he has turned against him. DJI dominated civil drones by processing Western Maps. The pattern is repeated: West delivers knowledge, China absorbs it and begins to overcome it. Terry Gou, founder of Foxconn, understood that it was better to sacrifice immediate margins in exchange for tie up a company like Apple to get free training by US engineers. Between the lines. China applied what we could call “reverse Trojan horse.” Instead of infiltrating, it attracted Western companies to come voluntarily. Apple’s is a paradigmatic case: for years he thought it was she who was conquering China, but the reality seen with perspective is that It has been China who has conquered Apple. Examples: The progressive assignments of sovereignty. Apple has accepted content restrictions or Mandatory storage on local serverssomething that led many hands to many heads at the time just for the EU to end up demanding something very similar. Logistics dependence without turning. There is no plan B, leaving China would be a slow, expensive movement that would require many years and many dollars. The massive transfer of knowledge. The aforementioned formations to millions of Chinese workers, the investments of more than 7,000 million in own equipment for foreign factories. China has absorbed that know-how. Yes, but. Apple generated thanks to this a company of 3 billion dollars. In 2000 it was around 4,000 million. Thousands of times less. That growth could not have happened investing elsewhere. Tesla would have taken much longer to master the electric car without Chinese industrial capacity. The problem is the aforementioned: there is no medium -term plan can not have it. Without China, Apple cannot manage its complex logistics, its millions of daily components. Nor access engineers to dominate them. And now… Apple is working with Alibaba to take Apple Intelligence to China for legal imperative. Is being more complicated than it seemed. And bytedance I would prefer to close Tiktok in the United States rather than sell its valuable algorithm. The employer is also repeated here: Western companies seek to access the Chinese market delivering their most valuable technology. The threat. China is increasingly dominating the massive adoption of AI with models mainly open source. Tencent has already integrated Depseek in Wechat For its more than one billion users. In China, AI is not a separate application, but is integrated into what is already widely used. Possibly the next generation of intelligent agents will repeat the pattern of Apple and Foxconn. But in the field of software. China is not winning the data career spying on the West. He is winning for having opened the door for the West to teach him everything he needed to know in exchange for greater quarterly benefits. Today the student has become a teacher and is the one who puts the standards. In Xataka | For Apple, the price of its iPhone was sacred.

The United States is creating “the iPhone of AI”. China is doing “the Android of AI”

by

There is an interesting paradox in the current development of AI that says more about geopolitics than about technology: USAtraditionally leader in proprietary software and monetization, is building closed models of AI. Chinahistorically more restrictive with the flow of information, it is leading the open source AI. An investment that is not accidental: each block adopts the strategy that best serves its structural interests. → United States (OpenAI, Anthropic, Google), is building the equivalent of the IPhone of the AI: Very sophisticated systems. Vertical integration. PUPLE POLIDED PREMIUM EXPERIENCES that justify charging for access. The logic is clear: when you control the best GPUS, the main cloud services and you have the capital to train the most advanced models, monetizing that advantage through payment APIs makes immediate economic sense. It is the model that has holding American software for decades. → China, on the other hand, with Deepseek, Qwen and Minimax Mastering the rankings of open models, it is creating the Android of the AI: A free and modifiable ecosystem. Downloadable for local use without depending on payment APIS. Permissive licenses without business restrictions, Unlike Meta with Flame. Accessible source code for independent research and development. As we said at the timethis approach is not due to altruism, nor by cultural difference. It is a strategy based on creating global dependence on a Stack Chinese technological when American becomes inaccessible. Or at least, to present it as a very attractive alternative even before seeing its results. It is true that he calls is American and is also in the league of the greats being open source (With an asterisk of the size of Mestalla). A habitual hypothesis also seems feasible: that target was released precisely because it was behind. The classic defensive strategy to erode the advantage of leaders. China does it from another position: growing strength. And in addition, having to deal with access restrictions to western markets. When your rival controls chips and cloud platforms, and can cut the tap at any time, the only way to create an alternative ecosystem is to make it so accessible that the world cannot ignore it. Soft Power Technological: give today to dominate tomorrow. That, or cling to developing markets plus the gigantic domestic market. This is how Huawei stopped competing to build a parallel reality. The numbers speak alone. According to the Benchmarks of artificial analysis (based in California, not in Shenzen), The three best open source models leave China. Each startup that Depseek uses instead of GPT, each country of the southern hemisphere that displays Chinese models because they are free, each university that trains over Qwen instead of Claude, is another node of the ecosystem that the United States cannot censor, regulate or disconnect unilaterally. It is a story very similar to that of The slow but unstoppable Chinese independence of GPS: In two decades it is no longer that I do not need it, it is that Beidou has reached 140 countries. It is also true that There are traps in both strategies: The American model generates immediate income but creates incentives for the rest of the world to look for alternatives, especially when commercial wars are intensified. Competence. The Chinese model conquers users but at some point it will need to monetize without frightening its base. The latter is something that Google learned with Android for the bad ones: after conquering 70% of the world, it began to monetize it aggressively and ended up receiving huge fines in Europe, antitrust demands in the United States and Chinese alternatives … as Harmonyos de Huawei. The circle closes. The lesson is that giving technology to create dependence works, but monetize that dependence once established attracts the attention that nobody wants: that of regulators. It is the dilemma that China will eventually face its “free” models of AI. The real battle is not for today’s best, but to control the Intellectual infrastructure Tomorrow. The United States sells the premium service. China gives the universal operating system. And the outcome will be that of two historically successful, but opposite philosophies: the American persistence by aggressively monetizing in front of Chinese patience to invest decades if necessary until it can lead. Immediate income against long -term dependence. Time will say. In Xataka | Four AI companies are monopolizing the intellectual future of humanity.

China did not intervene in the war to protect Iranian oil. Because your plan is longer than the conflict

by

For years, the relationship between China and Iran has been underpinned by a constant oil flow. However, the recent conflict between Iran and Israel caused Beijing He ordered his ships to turn in the Ormuz Strait. A seemingly technical gesture revealed something deeper: the limits of Chinese energy diplomacy. From partner to spectator. The recent climb between Iran and Israel, which included direct attacks and cross reprisalshe tested the link between China and the Islamic Republic. Although a truce promoted by Washington was declared, these weeks the gaze was set on this part of the planet. In that context, the international community looked towards Beijing, waiting for a clear gesture of support or at least mediation. But China opted for a prudent position: verbal sentences, called to dialogue, routine statements in the UN, According to Apnews. No military support, technical assistance, or real involvement. And that caught the attention, especially for what is at stake: between 80% and 90% of the oil that will export ends in Chinese refineries, which represents approximately 1.2 million barrels per day, According to France 24. Even so, Beijing chose diplomatic silence before the conflict. China is not the United States. And it does not intend to be either. While the United States maintains a network of military basesnaval fleets and strategic alliances in the Middle East, China has no comparable presence. Your only regional base It is in Yibutiand his attempts to expand to Oman or the Arab Emirates have been stopped, in part, by Washington’s pressure. As He explained The Interpreter, China has opted for a non -intervention policy. Its diplomacy in the region is pragmatic, transactional, guided by commercial interests rather than ideological affinities. “China’s footprint in the Gulf is commercial, it is not ready for combat,” said Craig Singleton, of the Foundation for the Defense of Democracies. For his part, William Figueroa, expert in China-Iran of the University of Groningen, It has been overwhelming In The Washington Post: “China has no capacity to militarily influence this conflict. Nor does it benefit from a broader war.” Although it is a matter of pragmatism. From Beijing, Zhu Feng, Dean of International Relations at Nanjing University, He has remarked In AP News that volatility in the Middle East “directly affects China’s economic security.” However, that does not mean that it will be absent. His greater diplomatic letter In the region was the 2023 agreement between Iran and Saudi Arabia, negotiated in Beijing. Although he was read as a Chinese geopolitical triumph, The Interpretter He has nuanced: “The distension had already been brewing with the help of Kuwait, Iraq and Oman. China simply gave him the final touch.” That discreet presence in the diplomatic field contrasts with its constancy in another key front: the energy. China has continued buying Iranian raw at reduced prices, Taking advantage of Tehran isolation For US sanctions. As has reported on their networks The journalist, Bachar el Halabi after the recent US bombings against Iranian nuclear facilities, oil exports to China did not stop, and in fact, they reached record levels. However, the relationship is fragile. In 2020, Iranian president Mahmud Ahmadineyad criticized the agreement of 25 -year cooperation between the two countries for considering it opaque and suspicious. Rumors about alleged Chinese military bases in Iran They circulated in the local pressfeeding distrust. When there is a dependency. This week, Reuters He has revealed that Washington has authorized that ethane cargoes – a key natural gas for the petrochemical industry – are loaded in US ports to China, as long as they do not end in Iranian territory. The operation, according to the letter released by the Office of Industry and Security of the Department of Commerce, is approved under the condition that the product is not discharged or redirected towards Iran. It may seem a bureaucratic technicalism, but it really says much more. This type of movements exposes how the United States continues to set the rules of the global energy game, even when it comes to exchanges between its two main strategic rivals. For China, the message is clear: its energy trade with Iran is still under surveillance. And for Iran, the warning is even more evident: Any attempt to avoid economic isolation, even indirectly, can be blocked from afar. The dragon rhetoric. Beijing wants to be a global referee, but he is behaving as a spectator. A recent example is the Defense Summit of the Shanghai Cooperation Organization (OCS), held in Qingdao, where Chinese Minister Dong Jun spoke of a world in “chaos and instability,” According to Deutsche Welle. The meeting was attended by their counterparts from Russia, Iran, Pakistan and Belarus. China projected symbolic power, but did not offer concrete solutions. In fact, even when they will threatened to close the Ormuz Strait – where 20% of the world crude, vital for China – pekin transits only the diplomatic tone, without major consequences. And, as multiple analysts explain, China has little appetite for risk. It is not yet willing to “risk the neck” in others. As It has concluded Craig Singleton in AP News, “When missiles fly, the so promoted ‘Strategic Association’ of China with Iran is reduced to communications. Beijing wants Iranian Iranian oil and headlines as a peacemaker, but let Washington load with the risks of hard power.” A strategic patience. China remains a key actor of the global economic order, but its energy diplomacy does not obey improvisation or shyness. On the contrary, its caution in the Middle East can be a symptom of a deeper strategy: observe, resist external pressure and prepare the terrain before intervening seriously. Beijing is not dragged by the logic of immediate power. He knows that in regions as volatile as Middle East, the cost of acting too soon may be greater than waiting. His silence, far from being absence, can be part of a longer play. Because oil unites, yes, but it also marks the rhythm of a power that is not in a hurry, … Read more

We already have the data on the table and, to surprise that no one is a dart for Tesla. 253,500 yuan. The price of Xiaomi Yu7 is 253,500 yuan, about 30,191 euros to change. It is an aggressive price that shoots towards the Model andcurrently with a price that starts from 263,500 in China, about 31,351 euros to change. Xiaomi Yu7: 253,500 yuan, about 30,191 euros to change. Xiaomi Yu7 Pro: 279 900 yuan, about 33,335 euros to change. Xiaomi Yu7 Max: 329,900 yuan, about 39,290 euros to change. The price is base, and varies depending on the colors we choose. In addition to the base colors (blue, green and orange), the rest adds 7,000 yuan, 832 euros to change to each purchase. The car can be purchased in China from the brand’s own app from 10:00 p.m. It is a launch that remembers more than that of a telephone than that of a car. The accessories. Xiaomi has found in the YU7 a machine to sell not only the car itself, but also its accessories. Transport Blankets Aluminum vessels Toy miniatures in different sizes Colors Carbon fiber finishes Personalized seats Aerodynamic Kits Economic base price for those who need more than the car. Personalization and accessories to the end for which he looks for a much more complete purchase experience. Why is it important. China is The country that buys more electric carsand win this market is key to a manufacturer who, since the birth of its automotive division, aspires to climb to Top 3. know-how Acquired with the Berlina Su7 to one of the most popular formats not only in China, but in the world: the SUV format. The Xiaomi Yu7 thus points directly to Tesla Model Y. The car of Elon Musk’s company It is the best selling SUV in Chinaand Xiaomi has refined specification specification to try to overcome it. They have demonstrated it with data. What does Yu7 offer. The Xiaomi SUV has a remarkably superior autonomy even in its basic version, with 835 km compared to the 593km of Tesla Model and RWD, according to the Chinese homologation cycle CLTC. The computing capacity is remarkably superior thanks to the Nvidia Thor platform, and is a much more technological car: self -adaptable suspensions, gigantic HUD with information from information from Hyperosetc. It also exceeds Model and in load speed (only 21 minutes to obtain almost 500 kilometers of autonomy), acceleration, tip and useful space, a section to which Xiaomi gives special importance to be a family SUV, bending it in Tops. The Su7 has already marked the way. Xiaomi announced its first electric car just a few months ago, with the launch of the SU7. In less than a year, he has managed to overcome sales to Tesla Model 3, placing itself as the fourth best -selling car in China at the beginning of 2025 Analyzing the global photo of sedan vehicles. At the end of 2024, the Xiaomi Su7 entered the top 20 of best -selling cars in China, with an unbeatable ByD and a Tesla with a model and in second position, above the other national models. It’s just the beginning. Xiaomi has just started selling electric cars, and has already managed to sneak into the Top 20 Chinese and Top 5 by categories. Beyond numbers, it has proven to live up (or above) of giants of the sector such as Tesla, Byd or Geely, with dynamic records in the largest dynamic benchmark to which an electric car can access: The nürburgring circuit. He already told us Abi Go in 2022: The electric car will be a fundamental piece in the Xiaomi ecosystem. And if we are clear is that there is something that the Chinese company obsesses as anyone: sell more than its rivals.

The two most important chip companies in China have a problem: the 5 Nm have been choked

by

In the middle of last May Dr. Kiman expert in the manufacture of integrated circuits who has worked in Samsung and who currently investigates for TSMC in the US SMIC (Semiconductor manufacturing international corp) I was about to Start 5 nm chips production. And also that he planned to launch his first 3 Nm nodes equipped with GAA transistors (Gate-alall-around) in 2026. This company is the largest Chinese manufacturer of semiconductors, and has been working on the development of its own 5 Nm photolithography with Huawei. For these two companies to have the ability to manufacture their own 5 Nm chips is crucial, but they are having serious problems with this integration technology. Dr. Kim pointed in May that the performance by wafer that SMIC had reached in this node was less than 30%, but now there are two antagonistic means, the Canadian platform Techinsights and the Chinese newspaper SCMPthose that support the difficulties faced by Huawei and SMIC. According to Techinsights the new laptop Matebook Fold Ultimate Design Huawei incorporates a soc Kirin X90 manufactured by SMIC. Nothing striking here. What is surprising is that the chip of this ambitious team is not produced in the 5 Nm node. SMIC is manufacturing it in its second -generation 7 NM node (N+2) using an integrated circuit production technique known as Multiple patterning. This strategy in broad strokes consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. China needs avant -garde lithographs, but endures thanks to mature chips The problem facing SMIC and Huawei, as we have explained in other articles, is that the Multiple patterning It has an upward impact on the cost of chips and the decrease in production capacity. These two Chinese companies have been forced to use this technique in their equipment deep ultraviolet lithography (UVP) because the prohibitions of the United States and the Netherlands prevent the Dutch company Asml from selling their machine their machines in Chinese extreme ultraviolet photolithography (UVE). The latter allow to produce more advanced semiconductors than UVP equipment. In Xataka The cure of some diseases "incurable" is already closer thanks to quantum computers According to Techinsightts, the new Matebook Fold Ultimate Design Matebook of Huawei incorporates a SOC Kirin X90 manufactured by SMIC In current circumstances it is reasonable to conclude that Huawei has not yet incorporated 5 Nm chips manufactured by SMIC in its most advanced equipment because the production of these integrated circuits is still very limited. This is what Techinsight and SCMP supports. And we think about it too. However, there is something important that we should not ignore. As I mentioned a few lines above, China needs avant -garde photolithographies To have the ability to make chips as advanced as those produced by South Korean companies Samsung or SK Hynix, Taiwanese TSMC or Intel or Micron Technology Americans. But, curiously, the Chinese semiconductor industry is surviving Thanks to mature chips. In fact, in 2024 it produced 12.5% ​​more than in 2023. It is not bad at all, especially if we are in mind that US sanctions and their allies prevent Chinese manufacturers of integrated circuits accessing UVE lithography equipment. And since 2024 they cannot buy more UVP lithography machines. For a good part of 2022 the production of China semiconductors suffered an important fall and did not begin to recover until the end of that same year. Of course, in 2023 this industry grew almost constantly, and in 2024, as we have just seen, the rebound was monumental, especially in the final stretch of the year. {“Videid”: “X81Felr”, “Autoplay”: False, “Title”: “A future without mole in China the industry changes the paradigm and we explain why”, “Tag”: “”, “Duration”: “182”} In this situation it is reasonable that we ask ourselves what kind are the integrated circuits that are producing the Chinese manufacturers. And the answer is very revealing: these are chips derived from mature integration technologiesusually of 28 nm or less advanced. After all, the semiconductors that we find mostly on electronic devices, appliances or cars, among other products, have been produced using them. More information | Techinsights | SCMP In Xataka | The US has declared the total war on Huawei: he does not want him to sell his chips for the most advanced outside of China (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news The two most important chip companies in China have a problem: the 5 Nm have been choked It was originally posted in Xataka by Juan Carlos López .
