An international team of researchers led by Natalia Dubrovinskaia and Leonid Dubrovinsky , from the University of Bayreuth (Germany), has achieved a milestone in physics : reaching a pressure of 1 billion pascals in the laboratory , three times what we can find in the nucleus. from the earth. This finding, published in the journal … Read more

Carbon dioxide emissions could be significantly reduced thanks to the replacement of metal parts in transport with composite materials with a mass four times lower , as investigated at the Eurecat technology center. By reducing weight and improving aerodynamics, fuel consumption will be much more efficient. Basically, we have to rely on polymer matrix composites … Read more

An artificial flower with petals that open little by little without the need for any external stimulus, such as light, heat or variations in pH, has been designed by researchers at the University of North Carolina, as published in the journal Nature Communications . In reality, the flower is useless in itself, except to demonstrate … Read more

The possibilities of contagion in hospitals through plastic surfaces for sanitary and food use could decrease thanks to a crystalline compound developed by researchers from the University of Malaga and the University of Buenos Aires. This coating with guanidine , a substance that adheres to the so-called polyvinyl chloride (PVC), a type of plastic widely … Read more

Electricity generation technologies, which use energy to move a magnet through a coil of wire to generate a current, but that is different in this newly designed battery where there are no moving parts involved, no emissions are generated and no maintenance is required, only direct generation of electricity . In reality, the battery is … Read more

Once discarded, they disappear in 36 hours . That is what happens with these sneakers when they are no longer useful to us. Biodegradable sneakers that are a prototype of Adidas. Biosteel is the new material created by the German company AMSilk with which the shoes are made, although the sole would be conventional rubber … Read more

The most closely knotted physical structure ever known has been conceived by a group of researchers at the University of Manchester, bringing with it the potential to create a new generation of advanced materials. The knot has eight crosses in a closed loop of 192 atoms , which is about 20 nanometers long (or 20 … Read more

Presented in Geneva at the International Haute Horlogerie Salon , the RM 50-03 watch is the lightest chronograph in the world thanks to its being made of graphene. The University of Manchester has collaborated with watch brand Richard Mille and McLaren F1 to conceive their graphene composite helmet known as Graph TPT . It weighs … Read more

The first papermaking process is traditionally considered to have been developed by the eunuch Cai Lun , advisor to Emperor He of the Eastern Han dynasty, in the 19th century. II a. For about 500 years, the art of papermaking was limited to China. And now it is precisely they who return with an important … Read more

The first metal-free electromagnetic metamaterial, which absorbs electromagnetic energy without heating , has been developed by electrical engineers at Duke University. Metamaterials are synthetic materials composed of many individual designed features that, together, produce properties not found in nature. Like a LEGO block This fully electromechanical dielectric (non-metallic) metamaterial is a dimpled surface with cylinders, … Read more

A new paint that causes sunlight to bounce (even off metallic materials) and, therefore, keep the surface cooler and also extend its useful life, has been developed by scientists from the Johns Hopkins University Department of Applied Physics. , in United States. A very important advance if we take into account that even the most … Read more

A new technology for making graphene, called GraphAir , developed by scientists at the Australian agency Commonwealth Scientific and Industrial Research Organization (CSIRO), makes it possible to create graphene from a common soybean oil used for cooking. Until now, the high cost of graphene production has been the main obstacle in its commercialization. Just oil? … Read more

More and more materials are used as raw materials in order to conceive 3D printed parts, from nylon to stem cells. However, what was still a milestone until very recently is that the raw material did not come from our planet . Which certainly opens the door to the idea that the future colonization of … Read more

While the First World War was about to break out, a man was absorbed in discovering some way to improve the barrels of the rifles . That man was Harry Brearley, and while researching metal alloys, he almost accidentally discovered stainless steel as if he had located some kind of gemstone in the sand. Metallurgical … Read more

There are already some products on the market specifically designed to prevent wine from spilling, however these devices require an additive on the neck of the bottle. A physicist named Daniel Perlman has managed to design a bottle that will no longer leak, without us having to make any modifications to it. The drip problem … Read more

Every day, the Earth receives around 100 tons of extraterrestrial matter in the form of grains of dust . 99% of these grains have an approximate size of between 0.05 and 0.5 millimeters. Sometimes bigger things fall, and hit the ground. They are meteorites. If you come across one, you better not touch it. The … Read more

Graphene is considered by many to be the material of the future, although the first commercial applications are still being delayed. One of many is a proposal from magnate Richard Branson , who has announced his intention to invest in a project to manufacture graphene aircraft. Graphene on an airplane As explained by Branson , … Read more

Fernando Uribe-Romo and his students at the University of Central Florida have detailed in the Journal of Materials Chemistry how to trigger photosynthesis with a material that converts carbon dioxide and visible light into solar fuel, while removing this from the air. greenhouse gas. Clean energy As Fernando Uribe-Romo himself explains : Adapting materials that … Read more

One more step towards the electronics of the future is what we can see in the following video, since it shows, for the first time, the passage of electrical currents through graphene. The authors of this milestone have been researchers from the University of Melbourne, managing to describe in images the behavior of electrons in … Read more

A group of engineers from the Massachusetts Institute of Technology (MIT) has conceived a material that, although it has a texture reminiscent of gel, has great consistency and mechanical resistance, allowing it to adapt to a highly changing environment . Inspired by a marine worm This new compound is inspired by the jaw of the … Read more

From biomass generated with cellulose present in corn cobs, a team from Heilongjiang University, in China, has developed a new technique to produce graphene .
