Materials are widely used to help heal wounds: Collagen sponges help treat burns and pressure sores, and scaffold-like implants are used to repair bones. However, the process of tissue repair changes over time, so scientists are developing biomaterials that...
Blue light from digital devices and the sun transforms vital molecules in the eye's retina into cell killers, according to optical chemistry research at The University of Toledo.
The process outlined in the study, which was recently published in the...
Industry uses platinum alloys as catalysts for oxygen reduction, essential in fuel cells and metal-air batteries, among other applications. Expensive and rare, that metal imposes tight restrictions on manufacture. Researchers at Ruhr-Universität Bochum (RUB) and Max-Planck-Institut für Eisenforschung have...
Scientists at Stanford University have designed an electrocatalytic mechanism that works like a mammalian lung to convert water into fuel. Their research, published December 20 in the journal Joule, could help existing clean energy technologies run more efficiently.
The act...
Nucleation is the formation of a new condensed phase from a fluid phase via self-assembly. This process is critical to many natural systems and technical applications including the manufacturing of pharmaceuticals and advanced materials, the formation of clouds, mineral...
EPFL researchers have developed a hydrogel – made up of nearly 90% water – that naturally adheres to soft tissue like cartilage and the meniscus. If the hydrogel carries repair cells, it could help damaged tissue to heal.
Some types...
The electron wave function A canister of liquid helium inside the blue cylinder allowed researchers to experiment with tiny electron bubbles only 3.6 nanometers in diameter. The work suggests that the wave function of an electron can be split...
Cornell University scientists Rachel Hestrin and Johannes Lehmann, along with collaborators from Canada and Australia, have shown that charcoal can mop up large quantities of nitrogen from the air pollutant ammonia, resulting in a potential slow-release fertilizer with more...
In a breakthrough that could lead to a new class of materials with functions found only in living systems, scientists at the University of California, Berkeley, have figured out a way to keep certain proteins active outside of the...
When it comes to designing and optimizing mechanical systems, scientists understand the physical laws surrounding them well enough to create computer models that can predict their properties and behavior. However, scientists who are working to design better electrochemical systems,...
Light-activated control of protein localization in mammalian cells. The protein is initially in the cytoplasm and excluded from the nucleus of the cell (blue area in the middle each cell). Upon illumination, the part of the protein that prevents...
