Graphene nanoribbons: it's all about the edges

Researchers have for the first time succeeded in producing graphene nanoribbons with perfect zigzag edges from molecules. Electrons on these zigzag edges exhibit different (and coupled) rotational directions ('spin').

Assembling micro components with laser tweezers

Researchers develop microscopic components and assemble them to larger objects with the aid of laser tweezers. They are thus establishing methods that one day may be utilised to manufacture machines in dimensions of a few micrometres.

Solar water splitting using particulate photocatalyst sheets

Researchers have achieved a solar-to-hydrogen energy conversion efficiency of 1.1% using particulate photocatalyst sheets developed by the research group. The photocatalyst sheet can potentially produce a large quantity of solar hydrogen inexpensively owing to its scalability and low fabrication cost.

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.
