* A virus is not a living organism, but a protein molecule (DNA) covered by a protective layer of lipid (fat), which, when absorbed by the cells of the ocular, nasal or buccal mucosa, changes their genetic code. (mutation) and convert them into aggressor and multiplier cells. * Since the virus is not a living organism but a protein molecule, it is not killed, but decays on its own. The disintegration time depends on the temperature, humidity and type of material where it lies. * The virus is very fragile; the only thing that protects it is a thin outer layer of fat. That is why any soap or detergent is the best remedy, because the foam CUTS the FAT (that is why you have to rub so much: for 20 seconds or more, to make a lot of foam). By dissolving the fat layer, the protein molecule disperses and breaks down on its own. * HEAT melts fat; this is why it is so good to use water above 25 degrees Celsius for washing hands, clothes and everything. In addition, hot water makes more fo

The researchers from Toyohashi University of Technology have found that cathode composites made by combining a sulfur active material and carbon nanofiber (CNF) developed using an electrostatic assembly method shows high discharge capacity equivalent to the theoretical capacity of sulfur and maintained high capacity after repeated charge-discharge cycles. All-solid-state lithium sulfur batteries using sulfur-CNF composites and electrochemically stable Li 2 S-P 2 S 5 -LiI solid electrolytes synthesized by liquid phase process showed better results. Low-cost Sulfur-carbon Composite It is required that a sulfur active material and a carbon material are appropriately combined for making high-performance all-solid-state lithium sulfur batteries. Conventionally, sulfur-carbon composites were synthesized by mechanical mixing, liquid mixing using a special organic solvent and complicated methods, in which sulfur is combined with a porous carbon material with a high specific surface are

Lubrizol Engineered Polymers  has announced that their  ESTANE® 3D TPU M95A powder TPU  has passed skin sensitization and cytotoxicity tests in accordance with ISO 10993-5 and 10993-10. This enables ESTANE® 3D TPU M95A to be a valuable material solution for product designers exploring 3DP for end-use applications that require skin contact. This achievement builds on Lubrizol’s long legacy of developing innovative materials safe for use in skin contact applications – from consumer products to medical devices – and reflects Lubrizol’s ongoing mission to improve lives. Broad List of Benefits Skin contact suitability is the latest attribute to round out a broader list of benefits that ESTANE® 3D TPU M95A brings to applications, including high levels of flexibility, durability, impact and chemical resistance, and energy rebound. Commercially available, ESTANE® 3D TPU M95A is certified for use on the HP Jet Fusion™ 4200 series 3D printing solution – the only TPU certified as such

Researchers from Chalmers University of Technology, Sweden, have created a new, rubber-like material with a unique set of properties, which could act as a replacement for human tissue in medical procedures. The material has the potential to make a big difference to many people's lives. New Risk-free Adaptable Material Based on Nanostructuring In the new study, the Chalmers researchers developed a material consisting solely of components that have already been shown to work well in the body. The foundation of the material is the same as plexiglass, a material which is common in medical technology applications. Through redesigning its makeup, and through a process called nanostructuring, they gave the newly patented material a unique combination of properties. The researchers' initial intention was to produce a hard bone-like material, but they were met with surprising results. Soft, Flexible and Extremely Elastic Material “ We were really surprised that the material tu

Researchers at EPFL have developed a new, high-precision method for 3D-printing small, soft objects. The process, which takes less than 30 seconds from start to finish, has potential applications in a wide range of fields, including 3D bioprinting. Making Tiny Objects with Precision and Resolution It all starts with a translucent liquid. Then darker spots begin to form in the small, spinning container until, barely half a minute later, the finished product takes shape. This groundbreaking 3D-printing method can be used to make tiny objects with unprecedented precision and resolution – all in record time. The team has set up a spin-off, Readily3D, to develop and market the system. The system is currently capable of making two-centimeter structures with a precision of 80 micrometers, about the same as the diameter of a strand of hair. But as the team develops new devices, they should be able to build much bigger objects, potentially up to 15 centimeters. “ The process could also be

A team of researchers from Montana State University is developing methods to infuse polymers with particles called nanocrystals that are made from cellulose, a primary component of plants. Whereas many regular plastics can combust when subjected to fire or very intense heat, the nanoparticles are designed to limit the flames and prevent their spread. Cellulose: The Building Blocks for Chemical Technologies By processing wood pulp of other plant matter using special chemical reactions, cellulose molecules become building blocks for chemical technologies that operate at the nano scale, which concerns things as small as one-billionth of a meter. Because the particles are so tiny, a relatively small volume of them can be mixed throughout a much larger amount of polymer. When the particles are coated in zinc oxide, a common ingredient found in many sunscreens, the zinc oxide's fire-resistant properties are imparted to the plastic. Nanocrystals for Fire-safety and Light-
