(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 ...
(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 can ...
Researchers have designed a graphene-based tattoo that can be directly laminated onto the skin with water, similar to a temporary tattoo. But instead of featuring artistic or colorful designs, the new tattoo is nearly transparent. ...
In the semiconductor industry, there is currently one main strategy for improving the speed and efficiency of devices: scale down the device dimensions in order to fit more transistors onto a computer chip, in accordance ...
(Phys.org)—In an effort to curb the adverse environmental impacts of paper production, researchers in a new study have developed a light-printable paper—paper that can be printed with UV light, erased by heating to 120 °C ...
(Phys.org)—Researchers have brought electrides into the nanoregime by synthesizing the first 2D electride material. Electrides are ionic compounds, which are made of negative and positive ions. But in electrides, the negative ...
(Phys.org)—Researchers have fabricated a smart skin that is self-powered by its frictional contact with the objects that it touches. When a honeybee crawls across the smart skin, the skin not only senses the insect, it also ...
(Phys.org)—Conventional membranes used for sieving atomic and molecular species cannot scale to the subatomic level, making them unable to separate hydrogen isotope ions (protons, deuterons and tritons). At the same time, ...
(Phys.org)—Researchers have demonstrated that transparent ink containing gold, silver, and magnetic nanoparticles can be easily screen-printed onto various types of paper, with the nanoparticles being so small that they seep ...
(Phys.org)—In an act of "nano-alchemy," scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and on ...
