Researchers have developed a photocatalytic system based on a material in the class of metal-organic frameworks. The system can be used to degrade pollutants present in water while simultaneously producing hydrogen that can be captured and used further.www.sciencedaily.com

A tiny layer of graphene flakes on a surface kills bacteria, stopping infections during procedures such as implant surgery. This is the finding of new research from Chalmers University of Technology, Sweden, recently published in Advanced Materials Interfaces.phys.org

A 2D MOF wraps around the bacteria to form a soft cloak that expands as the bacteria grow and split. The MOF protects them from oxygen, the reverse of a spacesuit, which protects astronauts from the airlessness of space.www.sciencedaily.com

A Stanford-led team has presented a multilayer anode consisting of a nickel–iron hydroxide (NiFe) electrocatalyst layer uniformly coated on a nickel sulfide (NiSx) layer formed on porous Ni foam (NiFe/NiSx-Ni), affording superior catalytic activity and corrosion resistance in solar-driven alkaline seawater electrolysis operating at industrially required current densities (0.4 to 1 A/cm2) over 1,000 h.phys.org

Multi-porous Co3O4 nanoflakes @ sponge-like few-layer partially reduced graphene oxide hybrids: towards highly stable asymmetric supercapacitors
Cobalt oxide (Co3O4) nanoflakes were grown into spherically porous sponge-like few-layer partially reduced graphene oxide (SrGO) using a sequential-electrodeposition process. Maximum specific/volumetric capacitances and sensible rate capability are obtained for the Co3O4 nanoflakes@SrGO hybrid electrodes.
