Xiaomi also has a folding mobile with which he intends to lead this sector. Now you can buy it reduced

by

Although the first brand that comes to mind when we think of a folding mobile is Samsung, there are other firms that also have models of this type. One of them is Xiaomi and his Xiaomi Mix Flipa mobile that once cost 1,299.99 euros but, now, you can take it (in its official store) for 699.99 euros. Xiaomi Mix Flip – 12+512GB smartphone * Some price may have changed from the last review A folding mobile with a good design As we have said, the Xiaomi Mix Flip It is the great bet of the Chinese manufacturer in the folding sector. If there is something for which it stands out, in front of other similar models, it is because it is light, since it only weighs 190 grams. Its main screen is type OLED LTPO with a 6.86 inch diagonalSy reaches 3,000 maximum brightness nits. As for its outer screen (the one you will see with the closed mobile), it has a size of 4.01 inches and offers a resolution of 912 x 1,224 pixels. Another of the notable things of this Xiaomi terminal is that it is one of the few folding mobiles that exist in the market in which the center hinge does not notice the touch. As for its battery, it admits 67 W Hypercharge Fast Cob. The photographic system signs it and is formed by a Triple 50+50+32 MP cameraso good photos are assured.

We lead all my life by measuring battery capacity in mobiles. Mah’s war makes no sense

by

How many more mah, better. We have been thinking about the specifications of a phone and, to a large extent, is something true. A greater capacity battery is usually a more capable battery with respect to a smaller. Despite this, there is a somewhat more complex unit of measure, but even more precise, traditionally used in the technical sheet of computers: Los watts-Hora (WHE). This is the most precise way to determine how long we can use our device, without leaving the capacity to your fate. We are going to explain, without delving too much into technicalities so as not to complicate your life, why we have been imprecisely measuring the battery capacity of our mobiles. Why do we measure in mah. The commercial standard for the phones battery is the Miliamperio Hora, a very useful measure for small devices with constant voltages. In addition, it is much more striking to indicate closed figures, such as 5,000mAh, than to tell that your mobile has a 19.4 Wh. However, its two main problems are, in the first place, when there is a voltage variation (you will soon understand why) this measure ceases to make sense. Although MAH is easy to understand, it does not provide an exact estimate of available energy, which can lead to incorrectly assume how long the battery will last in specific situations of use. Water measurement time. The watts -hora (WH) are the most precise unit to measure battery capacity, since they reflect the amount of energy available depending on voltage and current. He watt (w) It is the power unit, which indicates how much energy is consumed per unit of time. It is more useful to know how the battery will be used during the daily use of your mobile. The battery voltage is not constant: it is varying as its percentage of load and useful life changes. A battery, At the end of your useful lifeIt does not provide the same voltage as when it is new. In fact, if you have a modern car or motorcycle, you surely have access to real time voltage and you will see how you change as you use the vehicle. The mobile battery is lowercase compared to these, but also suffers small voltage variations. The ease of calculation. Even if the voltage was constant, the watts time would be an ideal measure. For example, if your mobile phone had a 5,000mAh battery and a typical voltage (the most common in phones) of about 3.85V, that battery would translate into 19.25 WH (capacity (MAH X Voltage / 1,000). Knowing the data, it would be enough to know the consumption in watts to deduce almost exactly how much the battery would last. In a concrete situation, as a very demanding game that leads to consume 6W constantly the division would be easy: 19.25 wh/6W = 3.2h. A data that stables: about three hours of screen with the mobile spending all rag This is why in segments such as computers, where consumption is crucial and marketing (something) less important, WHH is established as a standard to measure battery capacity.

Every time you think about everything the Romans managed to do, remember that they did it intoxicated with lead

by

Who will not like the Roman Empire? A little over a year ago, thousands of women from all over Spain asked their boyfriends, friends or husbands to How much they thought of the Roman Empire. And, at least according to the meme, the answer was: a lot. What we just discovered hidden in Arctic ice is that, in short, we think too little: the Roman Empire He raised one of the civilizational works more impressive in the history of humanity and did it with absolutely demential atmospheric levels. Lead that they themselves had launched to the atmosphere. Lead, lead everywhere. Examining lead in three Arctic Ice Cores 2,000 years ago, a team of deserting institute researchers They have been able to calculate The level of environmental pollution in Europe between 500 before Christ and 600 after Christ. The data is, to put it in a gentle and restrained way, terrifying. As They publish in Proceedings of the National Academy of ScienceAfter examining the lead isotopes stored on that ice, researchers could create a map of pollution by this metal throughout Europe. Not only that: they estimated their magnitude, the blood lead levels of the inhabitants and even discovered what had caused that enormous pollution. A guilty with name and surname. According to data, silver is at the origin of this problem. Or, rather, the Mining of La Plata. In general and for centuries, the miners melled tons of galena To extract silver. It is estimated that by each ounce of useful silver thousands of ounces of lead to the environment were released. To put it in numbers: “During the 200 years of apogee of the Roman Empire, more than 500 kilotons of lead to the atmosphere were released.” This, always according to the records of the ice centers, is 40 times greater than during the large environmental lead peak of the 70s (after which we began to withdraw it from gasoline, paintings and the rest of the products). And that, of course, there were consequences. We already know that lead is bad for health. Very bad. And not only because of infertility, illness or violence problems: I talk about neurological problems that translate into a considerable decrease in cognitive abilities and concentration. In practical terms, According to DRI researcherslead levels in Roman times had to decrease between 2 and 3 points of intellectual coefficient in the general population. “It does not seem much, but when it applies to practically the entire European population, it is a big problem,” Nathan Chellman explainedCo -author of the study. A problem that, seen in perspective, only increases the myth of the Roman Empire.

Europe wants to lead chips research of less than 2 nm. ASML is the cornerstone of your plan

by

None of The main semiconductor manufacturers The planet is European. TSMC, the company that leads this industry, is from Taiwan. Samsung and Sk Hynix are South Korean. Intel and Micron Technology are Americans. AND SMIC is China. This panorama invites us to accept that Europe has lost the train of the production of integrated circuits, but, in reality, it is not so. At least not at all. And it is that the old continent has ASMLthe Dutch company that leads the design and manufacture of photolithography equipment that is necessary to produce avant -garde semiconductors. And it also has IMEC, an integrated circuit research center founded in 1984 and housed in Leuven (Belgium). It is the most experienced laboratory in the tuning of new integration technologies that we have in Europe. IMEC and ASML work side by side to go beyond the 2 nm Europe does not have the expertise of the US, China, Japan or South Korea when it comes to the industry that develops in its laboratories. In what remains a global power is in border investigation. If we look beyond the semiconductors and look, for example, in Quantum computerswe will verify that the Max Planck Institute of Quantum Optics housed in Garching (Germany) and the Quantum Computing Center of Delft (Netherlands) are two leading institutions in the research in quantum computing. Europe seeks to develop the necessary integration technologies to produce semiconductors beyond the 2 Nm barrier IMEC has that same prestige, but in the field of innovation in integrated circuits. This is the reason why in May 2024 The European Union decided deliver a subsidy 2.5 billion euros To put a pilot line that will allow the manufacture of avant -garde semiconductors. This subsidy will be part of the ‘Chips Act’ program and has a very specific purpose: to develop integration technologies that are necessary to produce semiconductors Beyond the 2 Nm barrier. This is, in short, the European plan. And it is that IMEC intends to put its technology in the hands of European companies that are dedicated to automotive, telecommunications or the manufacture of medical devices, among other sectors. Diversification can play in your favor because it will contribute to developing the European technological ecosystem on a large scale. However, this research center is not addressing this project alone; He is working side by side with ASML. In fact, this company of the Netherlands has a crucial role in this plan. And he has it because he will deliver to IMEC the photolithography teams that his researchers need to bring to fruition the production of integrated circuits of less than 2 nm. ASML will install in this laboratory even your machine extreme ultraviolet (UVE) and haute openingwhich is the most advanced semiconductor production team it currently has. In fact, the technology of this machine is the only one that is capable of take us beyond the 2 nm. One more note to conclude: the collaboration of IMEC and ASML also seeks to develop integration technologies for DRAM chips, the Fotonic silicon and advanced packaging techniques of integrated circuits.

China prepares to lead the manufacture of chips for advanced weapons

China monopolizes gallium production. In fact, Up to 2022 monopolized 98% of the world gross Gallic, and this figure presumably has barely varied since then. For the country led by Xi Jinping This metal has a strategic value comparable to the one for the US due to its potential in military applications. And, in addition, Gallium export control allows China to respond to the sanctions to which the US and their allies are subjecting this Asian country in the scope of the semiconductor industry. Gallium is a very special metal. Its physicochemical properties make it suitable to be combined with other metals with the purpose of manufacturing a special type of integrated circuits called broadband semiconductors. These chips have three properties that make them very valuable to intervene in the manufacture of Advanced military teams: They support voltages, temperatures and frequencies higher than integrated conventional silicon circuits. During the 70s the US Advanced Defense Research Projects (Darpa) He dedicated many resources to the development of semiconductors in which Gallium was involved due to the potential he had in military technology projects. He Gallium Arseniuro (GAAS) played a fundamental role in the development of the global positioning system (GPS), and also in Radark tuning and precision weapons. China has taken a very important step forward Currently, Gallium Nitruro (GAN), which also has Darpa’s backing, is being used to make state -of -the -art radars that are capable of accurately identifying smaller, fast and numerous objects at more distance. Each of these radars incorporates several thousand chips in which the gallium intervenes. Everything we have just seen invites us to reach an obvious conclusion: Gallium is an essential metal for the US. But this country is not the only military superpower on the planet. The Chinese army and research institutions have been working with Gaul for many years and developing technologies that allow you to use it Third generation advanced semiconductors. As we have seen, China has Gallium in abundance, but producing integrated circuits with this metal is not easy. Neither for the country led by Xi Jinping nor for which Donald Trump is currently governing. Modifying electrons energy levels, it is possible to accurately control climbing and reduce defects To manufacture gallium nitruro, silicon and sapphire substrates are often used, but the effectiveness of the processes used so far was moderate because the hexagonal atomic structure of the GAN causes the appearance of a defect known as climbing. In broad strokes this curious phenomenon triggers the displacement of groups of atoms in a certain region of the crystal, which affects its structure and reduces its properties. In fact, GAN manufacturing defects cause electric leaks, reduce their thermal stability and reduce the performance of semiconductors. Until now the researchers who work with GAN had difficulty understanding why these defects appear in the crystalline structure of this material. And also to deal with them. But the team of scientists led by Professor Huang Bing at the University of Beijing (China) has identified the cause which triggers the production of defects during the growth of the Gan Crystals. What these scientists have discovered is that modifying the energy levels of electrons it is possible to accurately control the climbing and reduce defects. “Traditional strategies to avoid defects include the use of different substrates and the adjustment of crystallization temperatures, but these approaches only address symptoms, not the cause,” Professor Huang Bing explained. If China manages to get this research from the laboratory and bring to production chains this technology will have the ability to manufacture cheapest GAN -GAN semiconductors, of more quality and a much larger scale. And at this juncture it will not be unreasonable to anticipate that it will be done with the leadership of the application of 3rd generation semiconductors in the military field and 5G technologies.

Catalonia is determined to lead the conversion and sale of the electric car. His great objective is called Madrid

by

It is fulfilled a month since aids to MOVES III PLAN For the purchase of electric cars they fall. Silence since then. From experience with what lived in other countries, the electric car needs Purchase aids If you want to gain ground. An ambitious, stable and lasting aid program is the one that has achieved that almost all of the cars sold In Norway, they are electric. On the opposite side, Germany has seen how Their sales collapsed After withdrawing the aid forced. Taking into account that Spain was costing to take off in sales, we run the risk of unplugged with this technology And take a step back in the penetration of this technology just now that brands begin to propose vehicles at more affordable prices, with options of between 20,000 and 30,000 euros. In the middle of all this context, the Generalitat de Catalunya has presented a project to reimprorate sales of this type of technology, which also depends on its own automobile industry. A plan that revolves around the electric car Last January 2025, plug and electrical hybrids added 11,358 units in Spain. Of these, 4,571 units were recorded in Madrid. It accounted for 40.24% of sales throughout Spain. The figure is far from any other that can shade. Catalonia is the Second most populous autonomous community From Spain and takes more than one million inhabitants to the Community of Madrid. Barcelona It is also the second largest city in Spain, only behind the capital. Despite this, in January they only enrolled 1,624 cars classified as plug or electrical hybrids. 14.30% of the total sales of the territory. Given this perspective, the Government of the Generalitat has presented a plan to reimpulse the sale of this type of technology. The project, as we said a few days ago, has a transverse perspective because also Electrify the motorcycle fleet. The final intention is to make the electric car industry the stone on which the future of the automobile market turns. To achieve this you want to attack points that are considered keys: Multiply by five the recharge points network available in the next five years. Loans for self -employed and companies electrifying their fleets. Electrify 90% of the fleet used by the Catalan administration. The intention is to dedicate 150 million euros to sow the Catalan land of electric plugs. You want to move from the current 9,000 load points to a total of 45,000 plugs available. As for loans, a credit line of 400 million euros will be established to facilitate access to this type of technology and try to eliminate the barrier from the equation price. During the announcement of the Project, the Generalitat Catalan emphasized the importance of maintaining the good health of an industry that in the region generates 35,000 people occupied in 10,300 companies. By turnover, automotive represents the third sector of Catalonia.

The Persian Gulf has dominated the long era of oil. Now he is preparing to lead the era of solar energy

by

There is an increasingly more and more evident energy change, and even the countries we would never think are jumping to the renewable pool. Yes, I talk about the countries of the Persian Gulf. However, the tests are there: seven Chinese solar companies were generating more energy capacity than the world’s greatest oil companies. So, now, with their money and a lot of sun, everything indicates that they will give sorpasso. Wild investment. For very recently, Gulf countries have decided to invest in renewable projects. On the one hand, the United Arab Emirates They have announced a solar project 5.2 GW with a battery system, also betting on storage. On the other hand, Saudi Arabia is developing its energy transition plan through the Vision 2030 Plan. Recently, the Saudi Aramco oil giant has announced an agreement to start producing lithium in 2027. In addition, They are developing a plan to extract and enrich uranium For nuclear energy. Likewise, the Saudi country is carrying out different solar energy projects, some in Collaboration with China and others with Spain. And we can’t forget Kuwait, who already started two years ago has develop 17 GW of renewable energy and 25 GW capacity for the production of green hydrogen, which propose to export it to international markets. Data. According to the recent report by the International Renewable Energies Agency, the Middle East has Less than 1% of the world’s renewable capacity. However, from the agency they have detailed that the forecast for the next few years will be of accelerated growth. For its part, An analysis of the consultant Rystad Energypoints out that within five years, more than 30% represents total capacity in Gulf countries such as the United Arab Emirates, Saudi Arabia, Bahrain, Kuwait, Oman and Qatar. From the consultant they detail that this impulse is due to the weather conditions and the favorable conditions of the market. New solar panels will boost electricity generation in the Gulf Favorable energies. In the graph of Rystad EnergyWe observe that the Persian Gulf has two very different parts. The colored areas of orange, blue and green that represent renewable energies we see how they increase exponentially, especially solar. However, we see how nuclear and hydrogen have a slight growth that is maintained over the years. On the other hand, oil and gas, colored gray, although they are currently the main sources of energy, they will fall by 2050. China, ally or competition? The Asian giant has become a double agent in the energy transition, acting as much as a partner and competitor. On the side, Chinese companies such as Jinko Solar, Longi and Byd are providing solar panels, batteries and other technologies for the ambitious renewable projects in the desert region. On the other hand, China is carrying out the development of its own solar and wind projects. Besides, Your dominance over the global supply chain of batteries and solar panels gives you an advantage in the energy market. At the same time, its expansion in the Middle East allows you to gain influence in a region that has historically been dominated by fossil fuels. The change. The Persian Gulf is in the process of investing in renewables to mark its path to sustainability. However, they still have a stretch to travel because infrastructure and energy supply stability are still aspects that must be resolved.
