On their way to mass implementation, Perovskita cells have taken another step: 10 times more resistant

Perovskita’s solar cells are known for their lightness, managing to develop Ultrafin panels with different applications, such as The candle of a ship. However, the stability of this type of cell meant a challenge for its commercial viability. Now, a group of researchers has managed to extend the useful life of a Perovskita solar cell. Short. Scientists from the University of Surrey They have developed Perovskita solar cells that, by incorporating aluminum oxide nanoparticles, improve both durability and efficiency. Thanks to this finding, cells will be more resistant for large -scale application. The problem to be solved. Here you have to make an important comparison, because the solar cells of the study are of Perovskita that are more efficient and economical than those of silicon, so it has been one of the main objectives of the researchers for their commercial implementation. However, the main challenge was that cells They suffered iodine leakscausing the structure to react chemically reducing its performance. In addition, factors such as humidity, heat and oxygen accelerate this process. The investigation. Surrey’s team, together with the United Kingdom physics laboratory and Sheffield University, He has discovered that when integrating aluminum oxide nanoparticles (Al₂O₃) within the Perovskita layer, iodine can be trapped and prevent it from escaping. This simple but effective approach drastically improves the structural integrity of Perovskita’s solar cells, making them more resistant to weather conditions. The results. Solar cells containing nanoparticles maintained high performance for more than two months (1,530 hours), compared to just 160 hours of Standard Perovskita cells. In this way, the investigation has achieved an increase in the durability of ten times more. The incorporation of these nanoparticles has helped create a more uniform Perovskita structure, which has reduced the defects of the material such as moisture and has improved electrical conductivity. Iodine is not always bad. Unlike this study, iodine can be the result of a solution if the right approach is sought. A study group from the University of Beijing has achieved Integrate iodine into a Perovskita structure. In this approach it has stabilized the material and has avoided the degradation that has historically limited its durability. A great future. In 2009, Perovskita’s solar cells only converted 3% of solar energy into electricity, wasting the remaining 97%. However, Thanks to recent advancesits efficiency has exceeded 25%, increasingly bringing them closer to generalized commercial adoption. This progress highlights the great potential of technology, and with more studies, it is expected to continue increasing, approaching even higher figures and opening new opportunities for solar energy.

Spain has filled Europe with excellent tomatoes that do not know anything. It’s time to step further

The story is known: last year, the reputed French socialist policy Ségolène Royal gave a television interview in BFM.TV in which I accused Spanish tomatoes of being “false bio”to “deceive the consumer” and come to say that they were “surable.” Government, agricultural associations and personalities Like Jose Andrés They went out in Tromba to defend the Spanish product. So and today, the controversy should be to ask ourselves if there is something to learn from all this. But let’s start with the obvious. Spanish tomatoes are excellent. For decades, in fact, Spain has been the international reference of this product, and doing so is not easy. Remember that tomato is the fruit and vegetable culture more valuable What world. Only in 2021 they were consumed in the world More than 189 million of metric tons and represents 31% of all the vegetables that occur in Europe. That is, there is a lot of money in the tomato and there are many countries behind that money. Spain would not have been for years One of the great exporters of tomatoes from the world, nor would it have conquered all European markets, without extremely high quality and standards. Well know in Almería that a small failure It takes you out of the market in a matter of days. The kings of tomato … commercial. In fact, if we go down to detail, Spain nails three main types of best -selling tomatoes internationally: the balls, the Saladette and the cocktail. Within these typologies, the varieties of the Spanish field continue to excel in color, size and useful life. The problem is not that. The problem has never been that. The problem is that we have given Europe (and the rest of the world) just what they wanted: colorful tomatoes, good size and easy to handle “post-recreational.” And we have done it at a good price. That is, we have given them the best possible commercial tomatoes. The problem is that these tomatoes do not know Tomate. And commercial tomatoes lost the taste. In 2017, a team of researchers from the University of Florida led by Harry Klee They analyzed 398 different varieties of tomatoes with the idea of ​​tracing the genetic bases of their organoleptic qualities. His conclusions were that, while the smell-for-the balance of fruits such as banana and strawberry depend on a single volatile compound (or very few), “the tomato needs about 25 different compounds to build its unmistakable organoleptic identity. “ The composition. That are dozens of amino acids, sugars and well -balanced volatile compounds. A chemical balance that on the way to find better colors, sizes and durability, became something very difficult to maintain. And that, in fact, it has not been maintained: it is a common place to say that the tomatoes no longer know tomato, but the investigation He supports it. According to Klee and his team, commercial varieties only have 13 of the 25 volatile compounds that give the smell of tomato. There is life beyond commercial varieties. Faced with these varieties of great views, productivity and durability, we have other types of tomatoes: what is called ‘Heirloom’ (of ‘inheritance’ or ‘family relic’). A tailor drawer to talk about local or regional varieties, with little circulation, whose development process has allowed them to maintain a well-balanced flavor. It is not a miracle. We talk about less productive tomatoes (the plant can ensure more sugar in each fruit) and that, being little resistant to post-harvest handling “, have shorter distribution chains that allow greater maturation in Mata. That is, their technical limitations play against their commercialization, but in favor of their flavor. As is obvious, Spain is full of tomatoes of this type. Not only Barbastro’s pink tomato or Tudela’s ugly, no. The list is endless: the Montgrí de Girona, the Cor de Bou, the Mutxamel of Alicante, the Galician monfortes, the Avoa de Osdo, the tomatoes of the Sierra de la Culebra, the black tomato safe, the Mallorcan Valldemassa and a long etc. . No one in their healthy judgment can bite a well -matured mutxamel and take seriously that Spanish tomatoes do not know anything. I don’t know if Ségolène Royal compared a Spanish commercial tomato with A French Heirloom variety or simply I was doing politicsbut it is true that beyond all The inaccuracies and tone outputsthere is something interesting about what we can reflect as a country. Spain and the tomatoes of the future. In 2022 and for the first time in history, Moroccan tomato sold more than Spanish. And not a little: sold 21.3%. Gradually, the United Kingdom and especially France have begun to replace Spanish tomatoes for those from the other side of the Strait. There are many reasons behind this, but few solutions. And, although Spain is still very strong in the rest of Europe and is opening a hole in the North American market, the ‘sorpasso’ is a warning to navigators. The regulatory advantage of belonging to the EU is getting rid And what we started to see is an agricultural giant with mud feet. And it’s time to take it seriously. We know that to continue being an international reference in the sector we will have to launch one of the “agricultural transformations” more important in history, the question is whether we take advantage of our competitive advantage to lead these changes or engage in an international war that We don’t seem like we can win.

Kazakhstan is one of the world’s greatest uranium producers. Now has taken another step: its first nuclear power plant

In the geopolitical board of energy, the domain is not only measured in oil barrels or cubic meters of gas. There is a resource, silent but powerful, which is redefining the current panorama: uranium. While some countries look desperately reduce your energy dependenceothers have understood that true power lies in controlling not only the raw material, but the entire nuclear cycle. Russia has already taken the lead with A dozen centrals Under construction, but now Its largest supplier He also wants to become a strategic actor. New actor. Kazakhstan has decided to accelerate its nuclear development to address its growing shortage of energy. The government has approved the construction of Your first nuclear power plant and a plan to expand its nuclear industry. A referendum in October 2024 showed that 70% Voters support the construction of nuclear plants. This first nuclear power plant will be located in the village of ülken, in the Almath region. The government intends to build at least three more floors to make the most of its resources. Currently, feasibility studies and negotiations with international suppliers are being carried out to determine the technical and financial details of the project. The main financing will come from a Russian government loan with subsidies, and Samruk Energo It will lead the negotiations to guarantee cost efficiency. Energy shortage. The Kazakh country wants to reduce its energy dependence and face a growing internal demand. Despite being one of the countries with greater uranium reservesIt does not have an operational nuclear power plant since 1999. However, it manufactures pumping equipment for nuclear plants and seeks to expand the national production of reactor components and energy equipment. This strategy is aligned with the objectives of carbon neutrality and industrial modernization. An energy cluster. The government seeks to develop a “Nuclear cluster” that not only includes the energy plant, but also the local production of nuclear fuel. To do this, he has formed alliances with China and France. In addition, for nuclear reactors, it will have technology suppliers such as the Galo and South Korean country. The central will probably have a capacity of at least 3 GW, and more plants will be built in the future. Kazakhstan will also strengthen its electrical networks and better connect the western region with the national system. So what happens to Russia? The Kremlin remains an important actor in the global nuclear sector and has supplied Kazakhstan nuclear technology in the past. However, within the country, the concern that an agreement with Rosatom (the Russian nuclear agency) generates excessive dependence, both in technological and financial terms. The opposition has expressed fears that Russia use nuclear energy as an instrument of geopolitical influence. Problems in the past. Nuclear energy in the country has constituted a delicate issue due to the effects of Soviet nuclear tests in the region of Semipalatinsk. For that reason, as indicated Professor Kashi Nath Pandita, concerns about security and lack of transparency in regulatory processes are brought on the path of progress. Forecasts The project can be finished in the next decade, but advance it. However, the country still faces different challenges such as public distrust, environmental concerns and the need to choose a technological partner without compromising its independence. In the long term, this expansion could position Kazakhstan as an energy leader in Central Asia, reducing its vulnerability to regional energy instability and strengthening its presence in global competition for the control of energy resources.

It is no longer necessary to be registered to use chatgpt. And it is another step in OpenAi to be “the new Google”

OpenAI has eliminated the need to register to use the chatgpt web search, allowing any user to access their service directly. It is a movement that eliminates friction and democratizes access to its conversational search technology, which was already free. EITHER Freemium. If a few months ago OpenAi allowed the basic version of Chatgpt without registration, now this extends to Your own search engine. The context. This step is part of a broader strategy that we already anticipate: OpenAI wants to become the new Google. The company is transforming from a non -profit research laboratory to a technological giant who aspires to redefine our way of accessing the information. For more than two decades, Google has been almost exclusively our access door to knowledge and information, but Chatgpt’s emergence endangers its position. And in OpenAi they are aware of it. Between bambalins. The company is making a massive investment in infrastructure, building its own data centers in the United States and developing an AI -based search engine. All this while assume losses that exceed 5,000 million dollars annually. The growth potential is enormous: if you no longer need to register to search, it is much faster and more inertial to use it as a Google replacement. Turning point. The elimination of the mandatory registration arrives at a very specific time for OpenAI: it has reached 150,000 million dollars of valuation, and wants to reach 1,000 million users in 2025. That goal would place him at the level of technology giants, and hence a part, surely, the motivation of this movement: reach more people and eliminate friction.

The NFC takes its first big step in Spanish football. Atlético has adopted it to access its stadium

Atlético de Madrid has just become the first LaLiga club to implement technology NFC To access the stadium. It is good news that in turn uncovers the delay that this technology has had in Spanish football, who has opted much more for the codes QR as an alternative to entries and physical fertilizers. Why is it important. The NFC has been demonstrating more than a decade to be an efficient and safe system in payments and accesses, but Spanish football has remained anchored to the QRs, which have their advantages but slow down the process. The context. Asia or the United States normalized the NFC for a long time for all types of transactions, including access to enclosures and events. In Europe, and especially in Spain, we have maintained a certain resistance to adopt it. The NFC surpasses QR in three fundamental aspects: Speed: Transmission is immediate, without the need for focus or scan. Security: requires physical proximity and a biometric or PIN validation prior to the device. Reliability: It works in low luminosity conditions and does not depend on the brightness of the screen or the print quality. Between the lines. This Atletico movement tells us about the change in Spanish football mentality: technology is no longer just something to use in the field or in the locker room, nor a simple marketing tool: it is an element with which to improve the experience of the fan. The Atlético, in fact, is the first LaLiga club that has all the input and fertilizer formats: physical and digital card with QR, physical entrance or in PDF for mobile, and Wallet both of the fertilizer and the entrance.

The magnetic north pole has been moving rapidly. This is how navigation instruments follow the step

What do we talk about when we talk about the North Pole? The truth is that it depends since, on our planet we can distinguish two key geographical points that respond to this name, but with different “surname.” They are the magnetic north pole and the geographical north pole. Distinguishing them is key because only one of them has a fixed location while the other wanders in their proximity. But, in addition, it makes it faster. Reviewing the location. The new year has been released With an update that has gone more or less unnoticed but that is of the utmost importance: it is the world magnetic model (WMM) of 2025. The revision of the model not only includes the information about its current position but also of its displacements planned in the next five years . Accelerated movement. We have known for a long time that the magnetic north pole changes location and we know that the cause is in the changes in the magnetic field of the planet, a field generated by the connective iron movements of the interior of our planet. What is most striking is that, during the last decades the displacement of the magnetic northern pole It has accelerated. If for 300 years this point ranged between the islands located north of Canada, since the end of the 20th century and especially during the new century, the speed of displacement of this markedly accelerated. Now the magnetic north has already exceeded the geographical north and is closer to Siberia than from Canada. “The current behavior of the magnetic north is something we had never seen before. (…) In recent years he accelerated towards Siberia, increasing speed every year until about five, when he suddenly seized 50 to 35 km per year, ” explained in a press release William Brown, of the British Geological Survey (BGS), one of the institutions in charge of the development of the model. The world magnetic model. The model It is the result of the collaboration between the National Environmental Information Centers (NCEI) of the NOAA (National Oceanic and Atmospheric Administration) American and the BGS, as well as two intelligence agencies on both sides of the Atlantic. The model is used in various contexts, from aviation to commercial GPS and applications that use compasses on our mobile. The model includes a series of maps that not only indicate the location of the magnetic north but also mapped the changes in the Earth’s magnetic field, allowing to know the behavior of compasses at each point of the northern hemisphere. More precision. The latest version of the model, WMM2025will help improve navigation, especially in long -distance tours. As explained by the BGS, a trip between South Africa and the United Kingdom, using the old model, would imply a slight deviation of a degree on the way. The problem is that, over 8,500 kilometers, this very small deviation results in an error of 150 kilometers. The new model allows you to approach centimeters from the destination point. The version also incorporates a novelty: a high resolution map that will accompany the “standard” and that can be used in contexts where greater precision is required. This version has a 300 km resolution in Ecuador, notably higher than the 3,300 km resolution in the standard version. The next update. The WMM model is updated every five years, which means that we will have a new version in 2030, WMM2030. This assuming that I do not know any unexpected change in the speed or direction of the displacement that justifies an extraordinary review of the model.

Ryan Gosling would be one step away from starring in a new ‘Star Wars’ movie

Everything seems to indicate that after the success obtained by giving life to ‘Ken’ in the film “Barbie”, Ryan Gosling would be ready to embark on a universe much loved by the public. And it was recently reported that The actor would be in negotiations to star in a new film project Star Wars. Keep reading to find out what is known so far. According to information from The Hollywood Reporter, the film that will be directed by Shawn Levy will not address the stories of characters Luke or Anakin Skywalker. On the contrary, will explore a completely new narrative within this renowned saga. Likewise, the American portal reported that it would have been the Canadian actor who promoted the completion of the project. If a favorable agreement is reached for both parties, The filming period could begin in autumn 2025. Meanwhile, It is known that director Shawn Levy works together with screenwriter Jonathan Tropper, under their production company 21 Laps, in collaboration with Lucasfilm. However, this would not be the first adventure in which this pair has embarked, as they have already worked together in films such as: “This Is Where I Leave You” and “The Adam Project”, to name a few. If Ryan Gosling consolidates his participation in said project, this would become the next film in the world of Star Wars to enter productionfollowing in the footsteps of “The Mandalorian and Grogu”, starring Pedro Pascal, and whose filming ended last December and is expected to hit theaters in May 2026.
