Metamaterials have amazing potential--think invisibility cloaks and perfect lenses - but they are more likely to be found in a Harry Potter novel than a lab. To help bring them closer to reality, researchers have gone back to basics and demonstrated that the fundamental physics of metamaterials is more complex than scientists once thought.
Researchers have shown for the first time in mice that long and thin nanomaterials called carbon nanotubes may have the same carcinogenic effect as asbestos: they can induce the formation of mesothelioma.
A new review paper discusses the unique fibrous morphology of the dendritic fibrous nanosilica family of materials bestows them with several important properties that were brilliantly exploited for use in a range of applications.
By combining gold nanohole arrays and light irradiation, silver nanoparticles and polypyrrole can selectively be synthesized in the resonant area, and the distributions of chemical products and surface plasmon energy are well matched.
