New production technique for high-performance polymer could make for better body armor
Using a new composite nanoparticle catalyst, researchers have shown they can make degradation-resistant PBO, a polymer used to make body armor and other high-performance fabrics.
Read moreGraphene substrate improves the conductivity of carbon nanotube network
Scientists have combined graphene and single-walled carbon nanotubes into a transparent hybrid material with conductivity higher than either component exhibits separately.
Read moreSingle-particle spectroscopy of CsPbBr3 perovskite reveals the origin low electrolumine
Researchers have used the method of single-particle spectroscopy to study electroluminescence in light-emitting devices. They discovered that efficient charge funneling between individual perovskite nanocrystals and the phenomenon of emission blinking are responsible for the low efficiencies of perovskite light-emitting devices.
Read moreNew capsule can orally deliver drugs that usually have to be injected
MIT engineers designed a drug capsule that can carry insulin or other protein drugs and protect them from the harsh environment of the gastrointestinal tract. When the capsule reaches the small intestine, it breaks down to reveal dissolvable microneedles that attach to the intestinal wall and release drug for uptake into the bloodstream.
Read moreA simple way to control swarming molecular machines
The swarming behavior of about 100 million molecular machines can be controlled by applying simple mechanical stimuli such as extension and contraction. This method could lead to the development of new swarming molecular machines and small energy-saving devices.
Read moreThe story of thalidomide continues
An international study has unveiled a detailed view of how thalidomide, one of the most notorious drugs ever developed, causes abnormalities in limb and ear development. The findings may contribute to the re-emergence of safe, or non-teratogenic, thalidomide-derived drugs as a treatment for cancer and inflammatory diseases.
Read moreAccidental discovery of strong and unbreakable molecular switch
An organic material that can repeatedly change shape without breaking would have many useful applications, such as artificial muscles, pumps or as a switch. Physicists accidentally discovered a material with that property.
Read moreElectrode-fitted microscope points to better designed devices that make fuel from sunlight
Using an atomic-force microscope fitted with an electrode tip 1,000 times smaller than a human hair, researchers have identified in real time how nanoscale catalysts collect charges that are excited by light in semiconductors. It's a discovery that could help efforts to design devices that can store solar power for later use.
