The new largest plane in the world will be a beast to revolutionize wind. The big question is whether it will fly

In the Albores of the Ukraine WarRussia took control of the airport space of Hostomel. It was where two aviation monsters, Antonov-124 and Antonov-225They were trapped. The result of the attacks? Serious damage to one of the merchandise transport aircraft more used in Europe and Destruction of Antonov-225the largest plane in the world and pride of Ukrainian aviation. His loss has left a void that a startup wants to take advantage of with the Windrunner, the world’s new biggest plane Focused on the transport of wind turbines. The problem is that there are serious doubts that one day he undertakes the flight, but there is already an interested party that has nothing to do with him renewable energy sector: The Pentagon. Drive wind. The company after this ambitious project is Radiaa startup that considers that, in a Decarbonization scenario and with one artificial intelligence so voracious In energy terms, it is necessary to boost the installation of wind turbines throughout the world. The problem is that, to accelerate that installation, the cadence of Warmers installation And the transport of its elements, such as blades, is a problem. The towers can be set up by pieces, but the blades are another song. Radia considers that none of the load aircraft They have the ability to transport large blades, and there their plan with the Windrunner and a winery that will allow three 80 -meter blades, two of 95 meters or just just or barely one 105 meters long. And it will do it directly on an improvised landing floor at the construction of the wind farm. Comparisons are hateful. To put in context what type of plane we are talking about, if the Antonov-225 was a monsterthis Windrunner would be unqualifiable: Winrunner Antonov AN-225 Total length 108 meters 84 meters Wingspan 80 meters 88.4 meters Height 24 meters 18.1 meters Winery length 105 meters 43.3 meters Bodega volume 8,200 m³ 1,300 m³ Comes with a price. The problem is that putting such a plane in the air has a problem: fuel. For the 250 tons that the Antonov-225 could load, the Windrunner will stay in more modest 72.5 tons. Enough for its main mission of transporting shovels that in its largest lengths are around 60 tons. But autonomy can also be the big problem of that plan that allows winding throughout the world. Driven by four engines that will work with Sustainable Aviation Fuel, or SAFits autonomy will be up to 2,000. It will be its great limitation, since it will relegate it to an almost local use in Europe, America or Asia, with continuous reposses or with the need for shovels to be manufactured to those 2,000 kilometers of its destination. Windrunner on the left, Antonov An-124 in the center, Boeing 747-400 to the right Serious doubts. It is evident that the Windrunner is promising, but experts from the aerospace industry are not so clear that Radia can materialize their vision. The argument that analysts and experts of the aviation industry use is that Radia is a startup that will need a lot of money and have seen projects with better commercial arguments and lower technological risks. Also, and how we read in BBCRadia goes against everything that is usually done in this industry and, after testing a scale model in the wind tunnel, wants to speed up times and reduce costs passing from that model to scale to real -size test aircraft. As? Instead of building traditional prototypeslooking for digital design tools. And this is not like building a car on your own: once built, an overwhelming aircraft certification process begins. Virtually the interior of the Windrunner is a winery. Trust. In the same BBC article, Mark Lundstrom, founder of Radia, confessed that, although there are numerous challenges, the fundamental principles of the development of the Windrunner go through “not doing anything new and developing the minimally viable aircraft for aviation”. That makes them discarded alternatives such as the airships, which should go through new regulations and supply chains, and also that they have opted for a more traditional supply chain. For example, hiring experienced suppliers Like the Italian Leonardo for the fuselage, the American Afore to review the security or The Spanish Aernnova For wings and pylons of engines. It is not yet known who will provide the engines, but from Radia they commented to BBC that they have “selected an existing certified engine and are working to define the integration strategy in the fuselage.” That is, Radia is using already tested technologies and components, which will allow them to “the unit cost is proportional to the weight and size of the aircraft and, therefore, comparable to that of other civil aircraft of wide fuselage,” according to Radia’s spokesman. And it is expected that the 70% of suppliers of Radia are European. The Pentagon has taken his eye. Of course, Radia is not the first visionary Aerospace Company, but if you do not set the objective of building the Windrunner for its main objective of filling the aircraft planet, whoever has recently called at their door I have something interesting to offer. In May of this year, the United States Department of Defense signed an agreement with Radia To analyze if the Windrunner could transport military load. Although the weight it can carry is much lower than that of the missing Antonov-225, its winery is huge and is something that has captured the attention of the Pentagon. From Radia they maintain that its objective remains to serve the wind energy market, but recognize that the unique capabilities of its plane make it interesting for additional applications. Boeing heats engines. Radia aims to have several real -size test units to make a first test flight at the end of this decade. Again, an excessive ambition if we take into account that planes such as the aforementioned AN-225 barely made a few flights a year … and there was only one. And we will see how the pressure of … Read more

Nvidia and AMD can sell their chips from AI to China. The amazing thing is that to achieve this they will give the US a slice of 15%

Nvidia and AMD have agreed to yield to the United States a part of the income from the sale of certain AI chips in China. This pact unlocks the export of these components to the Asian country after months of uncertainty, but does so with that unusual consideration. The context. The US government It has been for years imposing all kinds of prohibitions to Chips exports and advanced technology from AI to China. The goal has always been avoid that the Asian giant could compete. The shot has come absolutely for the cylinder headand the advance of Chinese AI models –As Deepseek– And chips –Like Huawei– They show that this tactic has not worked. Nvidia and its H20 chips. To try to avoid those vetoes, Nvidia He developed his H20 chip with the intention of meeting the requirements of the US government – not selling its most advanced chips – and thus continuing to obtain income in China. They didn’t even solve the problem, and the US government prohibited the sale of that chip in the Asian country. A dilemma that also involved AMD. US has faced for months A apparently impossible dilemma: to sell Hardware from AI to China, or that of not selling it to him and that they develop them. AMD was also in identical situationabsolutely blocked to be able to sell their chips from AI to China, which meant a colossal problem for their global income, which are nourished with force of sales in China. Solution: Give me my slice. What has unlocked all this scenario has been, of course, money. In an unprecedented agreement revealed In Financial Timesthe US government will allow NVIDIA and AMD MI308 to export to China, but 15% of the revenues of these sales will go to the United States government coffers. Jensen Huang had already notified. The CEO of Nvidia, Jensen Huan, already warned that the blocking of the sale of its chips in China could cause A reduction of 15,000 million dollars In your income this year. The Asian giant represents 13% of the total income of Nvidia, but The sanctions They threatened the survival of this company (and AMD) in that country. A successful meeting. According to FT, the US Department of Commerce began to issue export licenses for the H20 Chips on Friday, two days after the NVIDIA CEO met with the US President Donald Trump. That meeting seems to have been the definitive After the theoretical initial agreement that both had reached less than a month ago. This had never happened. This “Quid Pro quo” is not preceded, FT analysts stand out, who point out that no US company had previously agreed to pay part of their income to obtain export licenses for their products. Even so, the pact follows the dictatorial position of President Trump, which In addition to its badly called reciprocal tariffs Does not to demand that companies manufacture the chips used in products that are sold there in the US, such as iPhone. The forecasts. According to analysts of the consultant Bersntein, Nvidia would have sold about 1.5 million H20 chips in China without exports controls. That would have meant revenues of about 23,000 million dollars, but now that figure is probably lower. Even so, it is expected that Chinese companies make great orders of both the Nvidia and AMD chips. A worrying precedent. Meanwhile, certain experts criticize this type of agreement. Liza Tobin, of the Jamestown Foundation, commented on how “Beijing must be gloating to see how Washington converts export licenses into sources of income. What will be the next one? Let Lockheed Martin sell F-35 to China in exchange for a 15 %commission?”. Image | Nvidia | Dominic Kurniawan In Xataka | China’s first avant -garde lithography machine is not the biggest US problem.

This graph shows how eighteenth -century corporations already doubled their value

In recent years, some technology companiesThey have climbed their capitalizations Meteorically to the point that, those known as the “7 magnificent”, already match or exceed the GDP of many countries. Every time one of the companies of this select group, formed by Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia and Tesla, Reach a new record The idea is reinforced that there have never been such powerful companies. However, history reminds us that this throne It is not new: There were corporations in the seventeenth and eighteenth centuries that, adjusting their value to inflation, doubled and even tripled the value of the current “7 magnificent”. Seven giants today, very great … but not so much In 2025, Nvidia has reached a capitalization of 4.2 billion dollars, Microsoft of 3.8 billion, Apple 3.2 billion, Amazon 2.4 billion, Alphabet 2.2 billion, goal 1.8 billion and tesla 1.1 billion. Together, the seven largest technological companies in the world total 18.7 billion dollars (European billion in a long scale). A huge figure, which represents The stock market weight Combined of the seven largest technological companies on the planet. However, if the graph prepared by Visual Capitalistleave a much more visual idea, and these figures pale when comparing them with the large business corporations that monopolized the lucrative trade between old Europe and their respective colonies. The data represented in the graph are extracted from the respective capitalizations of the companies in July 2025, as well as the research published in The Motley Fool In 2012. The figures of the companies of the seventeenth and eighteenth century are adjusted to inflation, which leaves us an approximate idea of the enormous power of these commercial corporations, causing the “7 magnificent” to seem mere startups to their side. The Dutch Company of the Eastern Indies: The Bubble of Flowers Founded in 1602 and financed by the Dutch government, the Dutch Company of the Oriental Indies (VOC, for Dutch) was the corporation more powerful of his time. During the speculative boom of the “Tulipomania“In 1637, which gave rise to the first economic bubble in history. During that time, the Dutch company of the Eastern Indies reached an estimated value of 78 million Dutch florins, which adjusted to inflation, would result in more than 10.2 billion dollars. That means that, a single company of the seventeenth century, came to be more than double the sum of Nvidia, Apple and Microsoft together. Unlike modern technological ones, the VOC not only traded with products, but also administered territories, negotiated treated, maintained its own army and even had the power to coin its own currency, functioning de facto as a overseas government. In modern terms, it would be a mixture of megacorporation, central bank and state geopolitical arm. The Mississippi company and the South Sea Company The 18th century also saw the corporate colossi flourish that, in the same way that they flourished, they withered to the pressure of the financial bubbles. The Mississippi company, managed by the Economist John Law Under the support of the French monarchy, it reached a value equivalent to 8,350,000 million dollars in 1720 (8.35 billion). Your model It was based on the exploitation of resources and commerce in the French colonies of North America, but ended up collapsing in one of the largest Stock bubbles of history. For its part, the South Sea Company was created in 1711 by the British Government with the intention of consolidating and refinancing public debt in exchange for exclusive commercial rights with South America, especially in the territories under Spanish rule. In theory, its business model was based on opening new routes and exploiting transatlantic maritime trade. In practice, their commercial activities were minimal. The promise of enormous future benefits promoted a stock market who triggered the value of his actions at exorbitant levels. Exactly the same as centuries later was lived with the Puntocom bubblea scenario that many compare already With investments in AI. In 1720, the South Sea Company reached a capitalization equivalent to more than 5,520,000 million dollars. However, the lack of real income, financial secrecy and unbridled speculation precipitated the collapse. He bubble burst It caused an economic crisis in the United Kingdom, dragging private, parliamentarians and members of the nobility, and forcing legislative reforms in financial markets.

China has just opened the first megatienda of humanoid robots. What comes later promises even more

What will it be to buy a robot like who buys a car? China responds with “Robot Mall”a megatienda in Beijing that its promoters present as the first 4S for humanoids: sales, spare parts, service and feedback of the user under the same roof. The idea is simple and ambitious at the same time, converting curiosids for daily use and maintenance contracts. What is a 4S (and why does it matter now). In China, the 4S was the answer to a simple question: what if I buy and maintain my car in the same place? This model is now exported to robots: a place to see what they do, how much they cost and how they remain with spare parts and technical service, in addition to measuring the customer experience. If it works, it converts curiosids for humanoids into informed purchase decisions. The appointment is in Yizhuang, the Beijing Alta District also known as Beijing E-Town. He opened on August 8, in parallel to the World Robot Conference (from August 8 to 12), and occupies four floors with about 4,000 square meters. On the ground floor, Immersive demonstrations of real uses in industry and health Together with reference humanoids such as Unitree G1, Ubtech Walker S or “Tiangong”. The second level is more interactive, with brain-machine interfaces, robotic arms and participatory exhibitions; the third centralizes diagnosis, replacement of components and remote operation and maintenance; The fourth floor is designed to close B2B agreements in negotiation rooms. What can you see and do there. There are seven major categories: medical, industrial, company, bionic, integrated, biped and wheels. Among the demonstrations, a robotic dog dressed in lion, a humanoid that dispenses traditional Chinese medicine, arms that paint, machines that brings or prepare coffee, and others that remove pharmacy boxes or serve drinks from a bar. Scenes that are a reflection of how advanced this technology is, but also of the path that still has. Are they sold to the public? Not all robots are ready to leave the store towards a living room or factory, but many can be bought or hired. Prices start around 260 euros (2,000 yuan) – thought for simple company or educational models – and scale up to several million yuan, a high range that is equivalent to several hundred thousand euros according to the platform and its configuration. In most cases, the sale includes installation, training and technical service. In the 4S format, the last “S” refers to Survey, which in this context means collecting the opinion and experience of the customer after the purchase. In Robot Mall this translates into periodic reviews, remote diagnosis, parts replacement and technical assistance, but also to collect data on how robots are used on a day -to -day basis. That information returns to the manufacturer to refine functions, improve reliability and prepare future versions. Why now. In 2024, China manufactured 556,000 industrial robots and concentrated two thirds of the world’s robotics patents, according to data from the Xinhua news agency. With figures thus, the opening of Robot Mall is no accident: it is part of a strategy to get the humanoids from the laboratory, put them in real environments and reinforce a sector that in Yizhuang already moves more than 10,000 million yuan in annual production value. What comes later. Robot Mall will not stay in this initial version. According to those responsible, in November 2025 they promise a 2.0 version, with more types of more varied robots and use scenarios. The idea is to expand demonstrations to more realistic environments and add manufacturers, reinforcing the role of Yizhuang as a nerve center of robotics in China. The images speak for themselves. The AP agency has prepared a photographic gallery with some of the best moments of the opening of Robot Mall. You can enjoy them directly from your website.

Smart Band 10 may seem more of the same. After a month on the wrist, it is clear why Xiaomi has chosen to repeat

There are times when a new model does not seek to break the previous one. There is no leap that, at least with the naked eye, seems decisive. Just a premise: keep doing what was already working, refining details. The Xiaomi Smart Band 10 It moves precisely in that direction. And although that approach makes all the meaning from the point of view of the product, it also raises a dilemma for the user: if you already know everything, Is it worth going through the box? In a new one 24/7 of the Xataka YouTube channelwe have tested this bracelet for 30 real days to discover if Xiaomi’s bet for continuity plays in favor … or begins to fall short. Mario Arroyo He has been testing the Smart Band 10 for a real month, without concessions: training in the park, home exercise, days of work and rest. And when he says that he has tried “in depth,” he does clearly. Because after several days using her, her impression was clear: “I feel it the same as its previous generation, or even the same as the Smart Band 8”The interesting thing is that this statement is not intended to be negative. It is a finding that Xiaomi has refined its formula without great shocks. Enough to recommend it? In the video we analyze that response in more detail. What we liked (and what is not) of the Xiaomi Smart Band 10 There is something that Xiaomi has managed to nail generation after generation: comfort. Mario confirms it after several days of training: the bracelet is so light that it practically disappears. But that physical advantage has a face B. “The screen is small and its format prevents you from seeing the data with comfort”, That is, the Smart Band 10 does not hinder when you train, but it does not help at all if you want to control your real -time progress. It is not an important lack, but a clue to the type of user to which it is directed: someone who wants to register, does not necessarily interact. As a day -to -day device, this smart band meets the essential. Who has had it on the wrist for weeks has been able to control their health clearly: steps, calories, heart rhythm, blood oxygen, sleep. In sports, we find the more than 150 already common ways, and a detail that he wanted to highlight: “A ‘running course’ where you have 10 different ways to start running with different activities. It seemed to me a cool addition, the truth,” he tells us. But there are also elements that have not changed, as he recalls: “We cannot pay with it because we have no NFC, and we don’t have integrated GPS.” One of the clear advantages of this generation is on the battery. The capacity has not changed – 233 mAh – but energy management is. In the first load, using it in moderation, the bracelet endured 18 days without disheveled. In a second attempt, with more training and the always active screen, he resisted 10 days. The data impresses, but the best is what it conveys: “Put the bracelet and forget about loading it. Not having to be aware of the battery of a device, is health … at least for me, ”summarizes our partner. The full load takes only one hour, but the magnetic connector has not improved with respect to previous models. To what extent does this compensate in front of a smartwatch? The answer, after 30 days of use, is in our video. Xiaomi has found a formula that works for it, and this generation confirms it. It does not revolutionize, but it also does not fail in many ways. “After 30 days using the Xiaomi Smart Band 10 the feeling I have is to see a movie that I like very much for the tenth time,” says our partner. A known experience, yes, but also solid. The price, yes, has risen slightly compared to the previous one. In addition, some details have improved … but is enough to justify your purchase against previous generations? There are things that are only appreciated after living with it day by day, and that is just what we try to address in The latest of Xataka YouTube channel.

During World War II, Australia sent an ornitorrinco to Churchill. Died on the trip and 82 years later we know why

In 1943, a camouflaged ship departed from Australia to England with an ultrasecreta load to the peculiar: An ornithorrinco called Winston, a diplomatic gift for British Prime Minister Winston Churchill. The creature died during the trip and for 82 years a German submarine was blamed. Some researchers They have discovered What really happened. Winston was not loaded by the Germans. Australian students They have resolved the enigma After examining the archives of the naturalist David Fleay, who captured the animal. The boat’s temperature records reveal that Winston died due to thermal stress by crossing Ecuador, not because of enemy attacks. Temperatures exceeded 27 degrees Celsius for a week, well above the survival limit of the species. Why Australia gave an ornitorrinco. In the middle of World War II, Australia felt abandoned by Great Britain while Japan approached the Pacific. Australian Foreign Minister Herbert Evatt knew that Churchill collected exotic animals and thought that an ornitorrinco, a creature that many considered at the time a taxdermic hoax, could tip the balance in favor of Canberra military support requests. The trip that should never have done. Winston was captured near Melbourne and embarked on a specially designed container, with burrows lined with hay, Australian stream water and 50,000 worms for the 45 -day path. David Fleay, the naturalist in charge, opposed from the beginning: no ornitorrinco had ever survived such a long trip and exports of the species were prohibited. The cause of “official” death. When Winston appeared dead in his tank, Churchill wrote to the Australian prime minister expressing his “pain” for loss. To avoid a diplomatic incident, death was hidden for years. When it finally came to light, the version that the Ornitorrinco had died from the stress of the attacks of the German submarines, a story that Fleay himself supported publicly. The clues of the logbook. Harrison Croft, a doctoral student at Monash University, agreed to files in Canberra and London that included interviews with the caretaker of the Ornitorrinco. “They made a kind of autopsy and he was very concrete: there was no explosion, everything was calm on board,” Croft explains. In parallel, an Australian museum team Digitized the collection Fleay staff, where they found the daily temperature record that revealed the real cause of death. Ship’s logbook. Image: Australia Museum Ornitorrincos Based Diplomacy. Australia tried again in 1947, sending three ornithorrincos to the New York Bronx Zoo. Betty died soon after arriving, but Penelope and Cecil managed to arrive healthy and saved to the country, even becoming authentic celebrities and a hook for the press at that time. The media expected them to be reproduced, but after a four -day “romance”, the thing did not go as expected. Image: Australia Museum The way to reproduce from an ornitorrinco is fascinating, since they are monoturem mammals, which means that, despite being mammals, they put eggs. In fact, they are one of the only five species of mammals that do this (the other four belong to species of Equidas). So when they saw that Penelope did not end up reproducing, it became a fun scandal at the time. In 1957 he disappeared mysteriously and Cecil died the next day of “broken heart”, according to the press. Since then, Australia strictly prohibited the export of ornitorrincos. Only two have left the country In 70 years, both to the San Diego Zoo in 2019.

Welcome to Hangzhou, the house of the ‘Six Little Dragons’

The Chinese city of Shenzhen is still one technological centers most prominent in the country. There they have their headquarters giants such as Huawei, Tencent or DJI. However, with the Boom of AI there is another city that is concentrating some of the most innovative companies of the moment and already stands like the new Chinese Valley Silicon. Welcome to Hangzhou. Alibaba. Jack Ma chose his hometown as the headquarters of the one who would become the Chinese giant of electronic commerce. Without knowing it, he put the seed of what Hangzhou is now. Alibaba attracted investors and encouraged the creation of a culture tech local; even former employees have formed other companies In the city. Alibaba Cloud Technology has also been key in the development of many AI startups. With Eight data centers In the region, Alibaba has made Hangzhou fertile land for the birth of numerous startups IA. The ‘Six Little Dragons’. This is how the group formed by the six most leading companies of the moment in China is nicknamed, all of them based in Hangzhou: University of Zhejiang. They call her the “Stanford of the East,”. Stanford University in California formed many of Silicon Valley’s outstanding figures and Zhejiang University is doing the same with the leaders of these companies. Deepseek, Manycore and Deep Robotics were covers by students of this university. According to SCMPuntil September 2024 the university had produced 102 Chinese startup executives. Government support. The city is home to numerous investment funds dedicated to incubating new technology companies and have very favorable policies that do not exist in other Chinese cities. They count on this SCMP video That students who want to form a company can get a loan of up to 500,000 Yuan (about 60,000 euros). If the company fails, the government covers up to 100,000 yuan and if it is more, up to 80% of the total loan. An example is that of Game Science, to whom the government paid the rental of the offices during the first three years and also helped them get the license to launch the game. Also the case of Brainco, a startup that as we said was based in Boston, but thanks to the incentives offered by the Chinese government, they managed to move to Hangzhou. Administrative efficiency. Another of the points where Hangzhou has stood out on other cities is its bureaucratic efficiency. Here was born Initiative called “A visit at most.” It means that if you have to do paperwork to set up a company or request some help, you just need to visit the administration once. It has worked so well that they are taking it to more cities. Return. The efforts to make Hangzhou a technological hub of reference are paying fruits. Official data indicates that Hangzhou’s technology industry It grew by 7.1% in 2024 and produced 630,000 million yuan (approximately 75,000 million euros), which is a third of the gross domestic product of the city.

It has been a European country

Germany has the third highest construction in Europe. With its 368 meters, the Fernsehturmor the Berlin television tower, it is a lighthouse in the German city. It will remain the highest construction in the country, but by little. About 130 kilometers, near the town of Schipkau, the works to lift another colossus have begun: the wind turbine higher in the world. And beyond its dimensions, which are imposing, what really attracts attention is that … it is not Chinese. Peculiar design. It was last year when we met the Project for this wind turbine. The idea is that of a tower with a center at 300 meters above the ground level and a total height telling 365 meter blades. It is very high, yes, but the blades are really less impressive than those of the Chinese wind turbine, with its diameter of 270 meters in which Three football fields would fit From one end to the rotor, which is capable of Alter the microclimate. To achieve such a height, the conventional “Palote” design would not be viable, so that those responsible for Gicon have devised a support similar to that of high voltage towers, but crowned with the turbine and blades. It is something that can be seen in this 3D animation: It is not a whim. Operating at that height has two advantages. One is that the wind speed is greater and, theoretically, it would allow to increase wind production by 40%. How we read in the middle HeiseJochen Grossmann, general director of Gicon, comments that “the performance of large -altitude turbines is double that of conventional facilities.” But it’s not just about take faster windsbut to be able to generate more electricity in fields that already had wind turbines. They have defined this project as a three -level generation, with Solar panels On the ground, installed on land where there were already traditional generators and, as their new ‘mills’ are so high, they could be integrated in parallel to the traditional ones. They would not be stolen wind and the gain would be optimized. Ambition. At the moment, they have already started the construction and, although they had planned to start producing this year, a small delay has moved the inauguration until some time of 2026. The idea, however, is to install up to 1,000 turbines of these characteristics by the country before 2030. Complaints. From Gicon it was announced that part of the economic benefits will be shared with the local population, but as we read in the middle RBBnot everyone has felt this giant wind turbine well. The Schwarzheide air club submitted an application to the authorities by stating that its location, about two kilometers from the airfield, will harm its activity. The Superior Administrative Court of Berlin, however, backed down the complaint. And it seems a curious case because the application was filed when the airfield had already been dismantled after the termination of the use contract between Schipkau and Schwarzheide. But well, although it seems that the times are too dilated for the construction of a single wind turbine (for the moment), from the company they have claimed that they prioritize the precision About the speed. And we will see if things march well in Germany and these projects can be exported to countries such as Spain, one of the countries with more wind installed.

We have found a centrifuge bacteria

We depend on plastic and, at the same time, we have been trying to find a substitute. That serves the same, but does not generate the tons of garbage and the microplastics that are generated today. There are several alternatives underway And now, a group of researchers believe there are found A convincing solution: use bacteria as a kind of living factory that produces the plastic of the future. And it is really promising: as resistant as metal, but that does not pollute when decomposing. Urgent alternatives. Seeing that plastic dependence and? Recycling is not something that is done too welltry to limit the use of plastic through different regulations. The big problem of this material is that, when degrading, it does not disappear completely, but is broken into particles known as microplastics. They end in rivers, seas, In food and In our body (They have been found until In human testicles or in the breast milk). And, in the process, many of these plastics release toxic substances such as phthalates or bisphenol A (BPA), highly harmful and related to hormonal problems and even cancer. Looking for that alternativeresearchers from RICE University and the University of Houston began experimenting to find a substitute for plastic that meet three conditions: Non-polluting. That is just as strong, or more, than plastic. That can be manufactured in a scalable way. Centrifugating bacteria. With that in mind, the researchers considered bacterial cellulose. It is a substance that produces some bacteria naturally and that is very similar to the cellulose of the plants, but finer. The finding is not this, since the bacterial cellulose was already known, but it has not been developed on a large scale due to its disorganized structure and complexity when using it. Therefore, the novelty is not the material, but how they have managed to produce it. To get that cellulose, they developed a “rotational bioreactor.” It is a machine in which they introduce these bacteria that produce cellulose while keeping them in a liquid. And what they have forced is to limit their movement so that they do not move at random. Basically, and as if it were a washing machine, they have put the bacteria there and have turned them in a specific direction during the production of the material. In this way, the fibers that make up the cellulose and that were previously disorganized, are now aligned in an orderly manner. Of course, in him studyresearchers expose that it is something that makes the difference, since, as with other materials (steel or carbon fiber, for example), when the fibers are aligned it is when the final material has those properties that make it unique. In the upper image, the messy fibers. In the lower one, the fibers created through that “bioreactor” Properties. Several, and very promising. The team has detailed that the new material is: Biodegradable. Resistant to replace plastic, but also some metals. Flexible and transparent. What resistance are we talking about? Of a traction resistance of up to 436 MPa, approaching the one presented by materials such as glass or aluminumbut adding to that property that of being flexible and transparent. It can be given. Masr Saadi is the main author of the study and one of the characteristics that he has outstanding is that they can be added to the material. “The method allows you to easily integrate various additives to nanoscale directly into bacterial cellulose, which allows customizing material properties for specific applications. For example, adding nitruro nitruro nanolás, the resistance rose to 553 MPA, but the capacity of the material to dissipate heat was also improved, tripling its thermal efficiency with respect to normal samples. Promising. “We imagine that these bacterial cellulose sheets, resistant, multifunctional and ecological will become omnipresent, replacing plastics in various industries,” says Muhammad Maksud Rahman, another of the researchers involved. And, although this bioplastic is in the laboratory phase, its industrial potential is evident. This multifunctionality would allow the material not only to containers that are currently plastic, but also to technical textiles due to their resistance and properties, also to heat dissipation devices, to Flexible screenslight structural sensors or elements that can be used in the construction segment. But, as we say, it is still a product that has demonstrated its potential in the laboratory, but it still remains for it to reach the market. If you end up doing it, of course.
