Refined protective layer for the 'artificial leaf'

A process for providing sensitive semiconductors for solar water splitting ('artificial leaves') with an organic, transparent protective layer has been developed by researchers. The extremely thin protective layer made of carbon chains is stable, conductive, and covered with catalyzing nanoparticles of metal oxides. These accelerate the splitting of water when irradiated by light.

Researchers invent tougher nanostructured plastic with 50 percent renewable content

Researchers have made a better thermoplastic by replacing styrene with lignin, a brittle, rigid polymer that, with cellulose, forms the woody cell walls of plants. In doing so, they have invented a solvent-free production process that interconnects equal parts of nanoscale lignin dispersed in a synthetic rubber matrix to produce a meltable, moldable, ductile material that's at least ten times tougher than ABS, a common thermoplastic.
