Dec 27, 2021 (Nanowerk News) An international scientific group has managed to measure for the first time oscillations in the brightness of a neutron star –magnetar– during its most violent moments. In just a tenth of a second, the magnetar released energy equivalent to that produced by the Sun in...
Nano-chocolates that store hydrogen
Dec 27, 2021 (Nanowerk News) An innovative approach could turn nanoparticles into simple reservoirs for storing hydrogen. The highly volatile gas is considered a promising energy carrier for the future, which could provide climate-friendly fuels for airplanes, ships and lorries, for example, as well as allowing climate-friendly steel and cement...
A breakthrough in microneedle patches
Dec 27, 2021 (Nanowerk News) The painful feeling of receiving an injection through a hypodermic needle or with the unpleasant sensation of swallowing a large pill is a globally familiar sensation. But what if a revolutionary and gentler way of administering drugs was in the works? For over two decades,...
Helium bath splash
Dec 27, 2021 (Nanowerk News) While working with helium nanodroplets, scientists at the University of Innsbruck, Austria, have come across a surprising phenomenon: When the ultracold droplets hit a hard surface, they behave like drops of water. Ions with which they were previously doped thus remain protected on impact and...
Gelatin foams show unexpected ultralong organic phosphorescence for optical applications
Dec 27, 2021 (Nanowerk News) Strong, lightweight and biocompatible foams glow in the dark when ultraviolet light is shone on them, RIKEN chemists have discovered (Journal of the American Chemical Society, "Ultralong organic phosphorescent foams with high mechanical strength"). This phosphorescence could have diverse applications, such as imaging biological samples...
