An Italian artist sold a sculpture for 15,000 euros. The material of that sculpture: “Air and spirit”

by

That does not spend too much time without having to put on the table the eternal debate of What is art and what not. This time, an intangible sculpture brings this debate without clear response to the conversations. Is art what one wants it to be art? Well, yes in broad strokes. But there are nuances that this air sculpture is exceeding. 15,000 for nothing. Or for “nothing”, as you look. The artist Sardo Salvatore Garau, born in 1953, is the signer of ‘Io Sono’ (I am), an invisible sculpture, but which, according to its creator, exists because it is made of “air and spirit”. It was auctioned in 2021 and sold for 15,000 euros, but has returned to the present thanks to a viral post of the British medium Pubitythat thanks to its 40 million followers has recovered this Performance Invisible, in a publication that is already approaching the million ‘like’. With certificate of authenticity. It reads “Intangible sculpture to place in a free space of any hindrance. Variable dimensions, approximately 200 x 200 cm. Work accompanied by an authenticity certificate issued by the artist. Archive work with N. IM5. This certificate It is all the buyer received, and Garau explained That is the void that gives the work its power, because it is able to stimulate the reflection and perception of the spectator. Intangible art Garau is not inventing anything: Intangible art It is an artistic current that exists since the time of the conceptual art of the 60s and 70s, when it was defended that the work is not manifested through a traditional physical object, but is built with intangible elements such as sound, light, vacuum or energy. Among its most notable growers are Sun Lewittwhich defended that the idea could be the true work of art, or Yves Kleinwhich presented an empty room in 1958, symbolizing absolute immateriality. Klein even sells some of these vacuum zones, underlining its symbolic value. Art or thymus? A few years ago, an artist sold two white canvases to a museum under the name ‘Take the money and run’: it is another Performance in which a poisonous sense of humor underlies, but It can also be interpreted as art. Although it is undeniable that it is an art that reflects, from the margins, about the commodification of creativity and about the business around artistic creation. “The underlying idea was to show how salaries can be used to measure the value of the work,” said Danish artist Jens Haaning when he delivered the blank canvases in response to an assignment: to recreate two of his previous works. That is, in that case, delivery and collection were part of the work. It was almost a manifest. Sources and bananas. Likewise, as a manifesto the famous ‘source’ of Duchamp, an inverted toilet can be interpreted whose real authorship does not finish being clear And that helped to start the eternal debate of What is art and what not. Or the last earthquake that the industry lived, the famous banana attached to a wall with American tapeit was also a clear posture taking about certain controversial issues. Its 6.2 million dollars caught their attention, but everything was part of its creator’s proposal. You can, of course, discuss whether it is a face proposal, but do not doubt its intentionality. This paints my nephew. The debate on whether conceptual art is more or less valuable than figurative art It will never end. Much more now that artificial intelligences enter Liza and even Human intervention itself can doubt As part of creation. The conversation about what art is and what is not part, in fact, of the conception and discussion about it, and Garau’s sculpture is still an apostille in an eternal controversy.

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.

We are injecting radioactive material into live rhino horns so that we stop consuming them

by

Perhaps you did not know, but to protect us from human nature itself, that capable of generating the most absolute chaos, most of the main airports and ports, including those of South Africa, already have the infrastructure necessary to detect radioactive material. So that? To detect nuclear weapons. Thus, in theory, we avoid smuggling between countries. In a twist, science has just found in this infrastructure a solution for stop poaching. Radioactive horns. The news is as surprising as it is true: a group of South African scientists has been injecting radioactive material directly into the horns of living rhino. The idea: make them easier to detect in border stalls. Behind the project is the Radiation and Physics of Health (RHPU) of Witwatersrand University in Johannesburg. Why the horns. Of course, the enclave where it is happening is not trivial. South Africa houses a Most of the planet’s rhinoceros And, as such, it is a critical point for poaching driven by, and here comes the key, demand from Asia. Yes, there the horns They use in traditional medicine for its supposed therapeutic effect (not tested). As Professor James Larkin explained, who runs the project, “every 20 hours in South Africa a rhinoceros dies from his horn.” In fact, before this amazing script, trying to save the rhino with another unexpected movement: investing in bonds. Not only that. The researchers indicate that the smuggling of these horns has currently made them “the most valuable false product in the black market, with a value even greater than that of gold, platinum, diamonds and cocaine. These horns hunted furtively are trafficked throughout the world and are used for traditional medicines or as status symbols”, They assure. Radioactivity injection process. Under the name Rhisotope Projectresearchers are drilling low doses of radioisotopes in the horns of 20 sedated rhinos whose health will be monitored over the next six months. We talked about two small radioactive chips in the horn zone that are then “finished” by spraying 11,000 microputs in the area. In the long term. If it succeeds, the program could be extended in the long term to include elephants and pangolines, as well as other plants and animals, According to the university. The material, in principle, would last five years on the horn, which “was cheaper than removing it every 18 months.” “Each insertion was closely supervised by expert veterinarians and there was very care to avoid any damage to animals,” Explain Larkin. “During months of research and evidence, we have also ensured that inserted radioisotopes do not involve any risk to health or any other risk for animals or for those who take care of them.” Poison for humans. In essence, once the radioactivity dose is inserted, the consumption by means of the products made with the horns will make them “essentially poisonous for human consumption,” they count at work. Be that as it may, the main objective is none other than identifying the smuggling attempts, to be able to be, before they leave the country. How the alarm jumps. Apparently, this infrastructure found in many airports works more or less simple. Anyone who tries to pass the radioactive horns would sound the alarms and a police response would be activated. By the way, scientists remember that the process is not harmful to animals, since the dose of the radioactive material is so low that it does not affect the animal’s health or the environment in any way. Figures that have led to the situation. Last February, the country’s Ministry of Environment said that, despite the government’s efforts to combat illegal trade, 499 of these giant mammals died in 2023most in state parks. In figures, it represents an increase of 11 percent compared to those of 2022. To get an idea of This sad realitywe talk about figures of up to $ 60,000 per kilo, which explains why the rhinoceros horn remains one of the most lucrative illegal markets.

A retiree and his children have stolen millions of dollars to Ford in office material. Indeed, lights, caps and bumper

by

Although in February this year Audi closed its Brussels plant After 75 years in operation, the road was not simple. In the middle of the workers’ protests, someone had an idea: take the keys of 200 cars, put them in a box and remove them from the factory. Clean, simple and with 200 kidnapped cars whose unit value was around 100,000 euros. As simple as keep a box under the jacket and go through the door. More complicated seems to steal the entire engine of a car. This is what was discovered A few months ago in India. For five years, up to 900 Kia combustion engines were stolen from their plants and has not been clear to what extent some worker of the company itself is involved. However, and although large, one can understand that engines from a factory have been steal if they manage to partially disassemble. But how can one take a car cap? And a bumper? This is what they wonder in Ford where a retiree and two children, company workers, have committed a “billionaire” robbery for more than two years. Hello, dad, I bring you a bumper The information, which comes from Detroit Free Pressa police note echoed in which it was confirmed that four people have been arrested for the theft of pieces of different Ford assembly chains that later sold on Ebay. Among those arrested is a former Ford employee but the identity of any of them has not been revealed so far. The pieces were stolen from three Ford plants, one in Deabane, another on a mounting plant in Michigan and one last in Flat Rock. In Motorpasion and The Drive They point out that three of these four men were family. One of them was a retired father and the other two were his children who had contact with a Ford employee. The extracted pieces were taken to stores where they accumulated for sale. A robbery that, according to the local police, is encrypted in “multimillionaire”. And it is that the four employees would have been subtracting and selling pieces for more than two years. The most curious thing is that it is not small or easy to hide pieces. Among the products found were car headlights but also Bumper and Capóslarge pieces therefore. An agent pointed to Fox That the stores where the pieces were stored were covered to the roof. The investigation is analyzing how these pieces could be taken out of the plant without attracting attention from other employees and will have to discover how they were eliminated from the inventory so as not to attract attention since all the pieces in a mounting plant usually have some type of code that identifies each piece. In addition, from the police they point out that they are still looking for new indications that take them to ships or warehouses where the suspects could save the pieces, taking into account the volume of them and the economic damage that it seems to have caused.

Argentina has sought in the basement of the Supreme Court and something very Argentine has been found: Nazi material

by

Argentina has maintained a somewhat complex relationship with the legacy of Nazism. During World War II, the country adopted a Neutrality position that allowed him to maintain “mixed” diplomatic ties, although he also took measures to stop the Nazi propaganda in his territory. However, after the conflict, the nation He became a refuge of numerous leaders and collaborators of the Nazi regime that fled from Europe, many With false documentation and under the protection of clandestine networks. Today, more than half a century later, someone has found another thread with Nazism … in the catacombs of the Supreme Court. An accidental finding. In the basement of the Supreme Court of Argentina, while organizations were carried out for the creation of an institutional museum, the operators randomly with something strange, several forgotten boxes for more than eighty years. The content, however, turned out to be an unexpected historical weight: notebooks stamped with Spastics, Nazi propaganda and other documents of the third Reich destined to disseminate the ideology of Adolf Hitler in Argentina in full boom of World War II. The finding, confirmed by the Supreme Court itself In a statementhighlighted the potential relevance of the materials to clarify episodes linked to the holocaust. In a recent ceremony, researchers, officials and representatives of the Argentine Jewish community formally opened part of the content, which includes thousands of red notebooks with Nazi symbols and registers of names and addresses that could correspond to members of the National Socialist Party outside Germany. The shipment that did not achieve its mission. Apparently, preliminary investigation allowed to track the origin of the boxes until the German embassy in Tokyospace from which it was sent to Buenos Aires on the Japanese ship Nan-A-Maru on June 20, 1941, when Argentina maintained a neutrality posture formal in the global conflict. The cargo was declared as personal effects by German diplomats in order to overcome customs controls. However, the Argentine authorities They detected their content And, concerned about the political implications of admitting Nazi propaganda, they sent the matter to the then Foreign Minister Enrique Ruiz Guiñazú. In August of that same year, Argentine officials opened some of the boxes and confirmed their propaganda character. Despite the German request that they were returned, a federal judge ordered his seizure and the transfer of the file to the Supreme Court, a space where the materials were archived and forgotten for decades. Argentine context in Nazism. We already said it at the beginning. Although the subsequent history made Argentina one of the more noticeable shelters Nazis and war criminals after the fall of the third Reich, the discovery of these boxes sheds new light on the efforts (previous and during the country’s conflict) to curb the ideological and organizational infiltration of national socialism. Already in 1939, the Argentine Attorney General had declared illegal and unconstitutional The activities of the local Nazi party, pointing them as an affront to national sovereignty. Likewise, it was forbidden that members of the German Nazi party access Argentine citizenship, showing an early will to cut any formal roots channel of the roots of the Hitlerism In the country. A time capsule. He counted In the New York Times Jonathan Karszenbaum, director of the Holocaust Museum of Buenos Aires, that the volume of the documents found is overwhelming. Although the entire content has not yet been examined, the thorough analysis of the notebooks is expected to provide concrete clues about The network of supporters and Nazi operators in Latin America during the war. The most disturbing question, however, is how and why This material remained hidden for more than eighty years in the heart of the Argentine Judiciary, a key institution of the Republic. The rediscovery, with all its symbolism, raises a unique opportunity to clarify dark chapters of the country’s history and reaffirm an institutional commitment to truth, memory and justice.

Android 16 premieres one of the most important redesign in the history of the Google system. This is Material 3 Expressive

by

Great day for Android users. Although we have already tried the first versions of Android 16in which there were hardly any changes with respect to the previous version, Google has formalized the changes that will reach this new iteration. Among them, one of the most careful designs in recent years, one that says goodbye to the above with Material Designand that completely redefines the system interface. Material 3 Expressive. From the arrival of You In 2022, Android has been quite stagnant in design. This is not bad news: Google’s operating system currently has a quite careful UI, and has given enough time for all applications to adapt to the interface. However, it already touched a change, and even more so with the suspicion that iOS 19 It will also be one of the biggest changes in UI in Apple’s history. Material 3 Expressive acquires its own identity. It is the natural jump after Material Design, and puts upside down what we had met to date. An even more casual, customizable and complete design language. A new design language. Android 16 will grind, a lot. Material 3 Expressive arrives with even more color palettes and a redesign in key aspects such as the notification panel, status bar (the classic Android vertical bar becomes horizontal such as … iOS), native applications, adjustments … It has been given a walk to the interface to show how well marry the new shades. The launcher remains practically identical, with a downhill bar, the icons with full freedom as usual and native widgets that have also been redesigned. It is important to emphasize that Google is showing this interface in a Google Pixeland that in the rest of the devices will present certain changes. Gmail in you material | Gmail in material 3. More news. Do you remember the “Live Activities” of the iPhone? They also arrive at Android with Material 3 Expressive, a joint work of Google with the rest of the developers so that applications can show real -time information. It is especially useful in food tracking, flight -related apps, and even in Google Maps itself. System animations, transparency effects have also been improved, and renowned the native Android apps themselves to adapt to this new design language. As you can see in the superior image, the changes are quite deep, and have as its purpose not only a more attractive design, but to improve the interaction (much larger and more accessible buttons). Also for Wearos. Google wants to unify the design language of its software, and Wearos It is part of it. Material 3 will not land only on Android, the Google operating system for smart watches will also reach. The interface in this type of devices will virtually completely changed, with much larger icons, redesigned icons, new color palettes and a much more intuitive experience. Everything has been rethink to make it easier to interact with these smaller screen devices. It announced in the same way Gemini’s arrival to Wearos in the coming months, to interact with him as we do with the smartphone. Gemini in the new versions of Android Auto. Of course, this new design will also reach Android XR and partially to Android Auto. There will not be a single Google product based on Android that does not enjoy the new material 3. For when. Android 16 will premiere material 3 from this month of May, so the next betas for the Google Pixel are expected to release the new design. As always, it will not be until the final version when this design is fully official and stable, so it is to arm yourself with patience to enjoy it in the rest of the devices. As always, in addition, it will depend on the efforts of the manufacturers themselves or not this design language. Many customization layers have their own language and do not respect Google design lines too much. Image | Google In Xataka | The best apps for Wear OS (2025)

Before the lack of steel, the ships of World War II began to be built with an unusual material: concrete

by

Close your eyes and think about the main material of a ship. Quite possibly Wood is the first Let it come to mind, and it is normal: we have millennia sailing in wooden ships, and we continue to do so. But it is also logical that the steel that dominated the XX and XX shipsand the Current marine monstersit is around ideas. And most likely you have not thought of another material: the concrete. But yes, for 150 years we were creating concrete ships, and far from crazy, it was the most logical idea. And even used in the first and Second World War. A Frenchman. A good day from the mid -nineteenth century, a French man named Joseph-Louis Lambot It occurred to him to build a boat. Not anyone: one of reinforced concrete. There was a problem: in 1848, they had no idea what reinforced concrete was. This material, basically, is the mixture between concrete and steel. Both combine to create something with much greater structural resistance and has been since their invention the basis of the most imposing, dams and almost any construction of the last century. Well, it was Joseph-Louis that came up with the two materials. At least, I know attribute The invention of reinforced concrete to this man. As always, there is controversy with the dates, with whom he patented the reinforced concrete, who built the first slab, etc. But well: Lambot wanted to prove his invention and built a small boat less than four meters with the aim of exhibiting it in the Universal Exhibition of Paris of 1855. Enough advantages. Basically, the interior was wire mesh covered by cement and Lambot’s idea was to completely replace the wood. The invention liked it, but it really did not attract the attention of ship manufacturers. Some barges were created for European channels, but little else. Everything changed when the Italian engineer Carlo Gabellini built the Liguria in 1896. It is the one we consider as the first reinforced concrete ship designed to navigate on the high seas. And, really, it made sense to create reinforced concrete ships. It is a material that has great corrosion resistance, so the marine environment does not damage the helmet, reducing maintenance (that also has it) and extending its useful life. It offered good thermal insulation, so perishable resources could be transported in better conditions and there were no fire problems. The Namsenfjord In the absence of bread … A few years later, the construction of these concrete ships expanded and other countries began to build, especially freighters. But of course, we are in 1914 and that means something happened: the World War I. And beyond the advantages of concrete against other materials, the world was forced to create concrete ships for a very simple reason: There was no steel. The militarization and industrialization of the belligerent forces caused a situation of Steel shortage. The ships were important, since the naval supremacy It has always been a determining factor in a conflict, but with the steel necessary for a destroyer you could create many other things. And the problem is that they had to continue building ships because there were resources to move worldwide. World War I. The revolution came with the Namsenfjorda Norwegian ship that, in 1917, showed that self -propelled concrete ships could be made. It was 26 meters in length and weighed a whopping 400 tons and most importantly: the United States saw that there was a potential in these ships beyond serving as charges propelled by an auxiliary ship. Thus, they created the Emergency Fleet Corporation program with the aim of producing 24 concrete ships. It was a failure: those who completed themselves, did it after the war, so it had to be allocated in other things. One was the SS FAithwhich was going to serve in the war, but in the end it remained to be used in transport work in the United States. It was thrown in 1919, it was in service until in 1921 it was sold to Cuba and had a length of 97.54 meters. A year after Faith, the SS Selmaa huge reinforced concrete mole of 129.54 meters in length that was launched just the day when Germany signed the Treaty of Versaillesending the First World War. It ended up using as a oil tanker in the Gulf of Mexico. With candles and a secondary support motor Demolish disadvantages. With the finished war, interest in the construction of concrete ships deflated. It still had advantages, because building them was much cheaper than making them in steel or iron, but if we mentioned a series of advantages, it is important to know the disadvantages (which exceed them, and by far). To match the resistance of a steel helmet, the concrete is thicker, which has several limitations. On the one hand, it weighs more, so it also has a major draft, the displacement of the ship is slower and more fuel is needed. That is thicker implies that there is less interior space for load, since the useful volume is reduced. That weight makes engines must be more powerful and that fuel tanks are also greater, so the investment in this part is greater. The dike to build it must also be monstrous because you cannot weld parts, such as steel, and then there is resistance to impacts. Second World War. The metal breaks, yes, but it has a greater elasticity than the concrete. This material, however, is much more fragile to impacts. A collision causes a crack in the helmet, and this on a ship that weighs so much is a conviction. That is why, after the great war, the concrete ship project was abandoned, leaving its construction practically limited to the loading barges, but then World War II arrived, and the steel needs of the previous one were repeated. However, the US program was not as ambitious as the one that began 20 years before and yes, concrete ships were … Read more

The Dana left 800,000 tons of waste and mud in Valencia. Now they will reuse for raw material

by

The Dana that hit the Valencian Community on October 29, 2024 caused great shock throughout the country, leaving more than 200 fatal victims. In almost five months, I They have generated More than 800,000 tons of waste mixed with mud, a huge figure, since the Valencian Community usually produces an annual average of 180,000 tons. And what are they going to do? In recent months we have seen with much of the national population has turned with the reconstruction and aid in the streets of the Valencian municipalities. However, given the data on the waste, the Ministry of Environment, Infrastructure and Territory He has decided to reuse The land mixed with flood waste for various works in landfills, quarries, agriculture and construction. Reuse. One of the points enabled to carry out this work is in one of the most affected areas of the catastrophe, Catarroja. The project consists of a machine that will make a screening between earth and waste, and then analyze them and make sure they are free of pollutants. Once treated, the Earth can be reused in different spaces. However, it is not there, because it is diversifying in other types of waste, such as tires, butane, scrap and mattresses, for its specific treatment. Reuse in agriculture. The floods caused by the overflow of rivers and ravines dragged large amounts of mud, debris and waste that affected both crops and soil quality. La Ribera Alta and the area of ​​L’Abufera, Key areas for agricultureThey saw how their rice crops, citrus and vegetables were destroyed. For this reason, working on the recovery of the affected soils trying to the sludge and the polluting sediments. However, mud samples taken in the area of ​​the Natural Park of L’Albufera are currently low, but concern persists on long -term effects. Other points to manage waste. The Ministry of Environment, Infrastructure and Territory has created Local collection points in which to accumulate the remains of the municipalities. Transfer points have also been enabled where to make a first crushing treatment, separation of metals and mattresses, located in Quart-Manises, Picasent, Catarroja and Alfafar. Waste energy management. While the Valencian Ministry has promoted this type of solutions, also It is exploring The possibility of incinerating some of this waste. In fact, incineration, as if it were a thermal power plant, allows transforming the heat generated into electricity. In fact, several experts They have defended That incineration reduces the percentage of rejection and, in addition, put as an example that burned waste produces ashes that are useful to develop, among other things, cement. In addition, Spain has advanced Significantly in the use of the biomethane, a clean energy source that can be generated from organic waste and landfills. The use of biomethane could complement the efforts of the Ministry of Environment, Infrastructure and Territory, by providing a sustainable energy solution and reducing the environmental impact of the waste generated by the DANA. Forecasts While the terrain is still being cleaned, one of the areas most affected by waste dragged by the Dana has been the Albufera of Valencia and its beaches. In them, more than 60,000 kilograms of garbage have been removed, including up to 36 varieties of different waste, such as tires, bumpers, butane, furniture and plastics. As cleaning and recovery efforts continue, more additional measures will have to be implemented to address waste dragged by future floods or natural catastrophes.

To build the longest world bridge, China turned to a peculiar material: bamboo

by

Although Saudi Arabia and Arab Emirates are immersed in a particular war for have the most beast buildingstalking about megaconstructions is to automatically look at China. The Asian giant has some of the works more tremendous, impossible bridges and even Higher abandoned skyscraper in the world. And one of those pharaonic constructions is the Hong Kong-Zhuhai-Macao bridge. With a length of 55 kilometers, it turns out that it is not only formed by steel and concrete: the secret ingredient is bamboo. And according to those responsible, continue like the first day. The bridge. After six years of planning and another eight of construction, in 2018 China opened the imposing bridge that connects Macao and Zhuhai. Its 55 kilometers, 6.2 of them underground, allow to convert a trip that previously lasted three hours into a ‘walk’ of just 30 minutes. And something that resonated in its day was the 420,000 tons of steel (which would be equivalent to 60 Eiffel towers), its more than one million cubic meters of concrete and the flexibility necessary to support typhoons and earthquakes. It is a barbarity, with an underground stretch that disappears and emerges from the sea It looks like a ship, but it is one of the two inputs/exits of the sea Bamboo. It turns out that the mixture added a plant: bamboo. And it is something that is not so weird, since, as we can read In South China Morning Post, China is the largest bamboo producer in the world and is something to give way. In the aforementioned bridge, this element was used on the panoramic platforms that are found throughout the same and the official newspaper Science and Technology commented a few days ago that, after six years installed, these panels have resisted sunlight, typhons and The corrosion of seawater, keeping “as solid as ever.” One more element. Lou Zhichao is a member of the Bamboo Research Institute of the Forestry University of Bamboo and pointed out that, apart from in China, bamboo occurs mainly in developing countries, which gives China a unique advantage and position to the time to process this bamboo. His team, in fact, has been developing more advanced technologies to process bamboo a decade, causing the process to emit less co₂ while encouraging the use of bamboo under constructions due to a relationship between resistance and weight higher than some alloys of some alloys of some alloys of steel. In addition, it can replace wood, plastic and steel itself in some constructions. Bamboo II. Now, although it has interesting properties, it also has a problem: it is prone to decomposition. This means that when bamboo facilities are done, toxic preservatives must be used that make the material much less ecological. The chickens that come through those that come out in environmental matters, basically. And, precisely, the Zhichao team has been working in recent years. One of its latest advances in research is a heat treatment that eliminates nutrients that cause the accelerated decomposition of the material. This allows to reduce its processing time by 50% while increasing durability outdoors without antimoho treatments. Adolfo Suárez Madrid-Barajas airport. You don’t have to go to China to see great structures in which bamboo is clear protagonist. In Spain we have examples such as Madrid airport Adolfo Suárez Madrid-Barajas, in which the roof of terminal 4 is formed by lames 100 mm wide of bamboo sheet. In total, there are 200,000 m² of bamboo with fire resistance and was the ideal material due to the peculiar curved forms of the terminal roof design. It is also a material that was raised for the Futurist Ciudad Oceanix City And the protagonist of the bamboo towers that Paris wants to build for 2050. And scaffolding. Beyond in places as punished as a bridge in such a complicated area and applications in other buildings, bamboo is absolute protagonist in Hong Kong. Specifically, in its skyscrapers, like an exoskeleton that really is a system of Scaffolding During the construction of buildings. For the rest, Zhichao continues to work to expand the use of bamboo as high quality material for several reasons. One because it absorbs 50% more co₂ than common trees. Another because it is estimated that its crop and market benefits some 50 million people throughout the country. And, therefore, he hopes that the government “finance the development of key technologies and reinforce regulation by national and local standards to boost the industry.” Industry tech. Apart from in structures, bamboo is positioning as a material that can be very useful in other sectors. An example is that of consumer technology not as an element that goes within the devices, but as part of the packaging. A few years ago, on a visit to the Innovation Center of Lenovo, They told ushow they were starting to use bamboo in the boxes of their laptops. Bamboo box to the right. On the left too, but after a year underground. The reasons were environmental due to the degradation of their fibers in normal conditions in nature. In fact, it can be buried directly in the garden to use it as fertilizer. In the photo that we leave just on these lines you can see two boxes, one new and one after a year underground, to appreciate its degree of decomposition. And, that sustainability is one of the keys (along with many others, of course) of decarbonization.
