Improving the toughness of graphene films

Thu, 04/09/2020 - 15:04
Researchers have developed black phosphorus (BP) functionalized graphene films, resulting in record toughness. The formation of covalent bonding between BP and graphene oxide (GO) nanosheets not only reduces the voids of GO film but also improves the alignment degree of GO nanosheets, resulting in high compactness of the GO film. After further chemical reduction and pi-pi stacking interactions by conjugated AD molecules, the alignment degree of reduced graphene oxide (rGO) nanosheets was further improved, and the voids in lamellar graphene film were also further reduced. The toughness of this graphene film reaches the highest value recorded to date.

Engineers use metal-oxide nanomaterials deposited on cloth to wipe out microbes

Wed, 04/08/2020 - 10:47
Nanomaterials are rough on microbes such as bacteria. They actually puncture the cell walls of the single-cell microbes, causing leaks and ultimately death. Put that on a cloth and you could have an effective, chemical-free disinfecting wipe.

Protein implicated in dry eye and PTSD visualized at atomic level

Tue, 04/07/2020 - 18:29
Researchers have captured an atomic-level high-definition image of a protein and the small molecule that binds to it. Both have been implicated in conditions including dry eye and post- traumatic stress disorder (PTSD). Full understanding of their structures will hopefully lead to development of an effective drug to regulate the protein's function.
