Pressure probing potential photoelectronic manufacturing compound

Molybdenum disulfide is a compound often used in dry lubricants. Its semiconducting ability and similarity to the carbon-based graphene makes molybdenum disulfide of interest to scientists as a possible candidate for use in the manufacture of electronics, particularly photoelectronics. New work reveals that molybdenum disulfide becomes metallic under intense pressure.

Free pores for molecule transport

Metal-organic frameworks (MOFs) can take up gases similar to a sponge that soaks up liquids. Hence, these highly porous materials are suited for storing hydrogen or greenhouse gases. However, loading of many MOFs is inhibited by barriers. Scientists now report that the barriers are caused by corrosion of the MOF surface. This can be prevented by water-free synthesis and storing strategies.
