Scientists have determined that the active sites for two reactions involving carbon dioxide (carbon monoxide oxidation and water-gas shift) are associated with small platinum particles and not single platinum atoms as previously proposed.
Researchers have designed one of the strongest lightweight materials known, by compressing and fusing flakes of graphene, a two-dimensional form of carbon. The new material, a sponge-like configuration with a density of just 5 percent, can have a strength 10 times that of steel.
In a microscopic feat that resembled a high-wire circus act, researchers have coaxed DNA nanotubes to assemble themselves into bridge-like structures arched between two molecular landmarks on the surface of a lab dish.
Researchers used extremely high magnetic fields - equivalent to those found in the center of neutron stars - to alter electronic behavior. By observing the change in the behavior of these electrons, scientists may be able to gain an enriched understanding of material behavior.
Researchers have taken biodegradable polymer nanoparticles encapsulated with cancer-fighting drugs and incorporating them into immune cells to create a smart, targeted system to attack cancers of specific types.
