Researchers develop a technology to enable unzipping of the graphene plane

Scientists have developed a technique, which enables unzipping of the graphene plane without uncontrollable damage.

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.

Optimized analytics reduce 'false negatives' in the detection of nanoparticles

Nanoparticles and their sizes are commonly detected using specialized analytical techniques. If nanoparticles are lost in the analytical apparatus, they are not detected, and a 'false negative' result occurs.

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.
