Nanostructures get better at harvesting sunlight for solar steam generation
One way to produce clean water is to heat dirty water until it turns into steam. As the steam rises, it leaves behind the heavier contaminants and can be collected and cooled, providing clean water. There are many ways to ...
Glassy carbon microneedles: A new transdermal drug delivery device
Microneedles are designed to infuse medications transdermally (through the skin) and relatively painlessly during clinical applications. In a recent study, Richa Mishra and her colleagues developed a new technique to convert ...
Revealing the retina: Graphene corneal contact lens provides robust, irritation-free topographic electroretinography
Our vision can be damaged or lost by damage to the retina—a sensory membrane lining the back of the eye that senses light, converting the image formed into electrochemical neuronal signals—resulting from two classes of ...
Fire alarm wallpaper detects, resists, and warns of house fires
Researchers have designed a "fire alarm wallpaper" made of environmentally friendly, nonflammable materials—including some of the materials found in bone, teeth, and hormones—that can detect a fire, prevent the fire from ...
Rubbery carbon aerogels greatly expand applications
Researchers have designed carbon aerogels that can be reversibly stretched to more than three times their original length, displaying elasticity similar to that of a rubber band. By adding reversible stretchability to aerogels' ...
First flashes of light observed from individual graphene nanoribbons
For the first time, researchers have experimentally observed light emission from individual graphene nanoribbons. They demonstrated that 7-atom-wide nanoribbons emit light at a high intensity that is comparable to bright ...
Graphene-based wearable e-textiles move closer to commercial production
The market for e-textile clothing is forecasted to reach $5 billion by 2027, according to the market research firm IDTechEX. And while graphene is expected to be one of the most prominent materials in wearable e-textiles, ...
Cheap, sustainable battery made from tree bark tannins
(Phys.org)—Tannins may be best known for their presence in red wine and tea, but in a new study researchers have demonstrated for the first time that tannins from tree bark can also serve as battery cathode materials. As ...
Clothing fabric keeps you cool in the heat
(Phys.org)—Researchers have designed a thermal regulation textile that has a 55% greater cooling effect than cotton, which translates to cooler skin temperatures when wearing clothes made of the new fabric. The material ...
