Twisted meta-molecules as they really are

Physicists at the University of Bath have devised a new and highly sensitive method to truly test the chirality of a material, eliminating the risk of false positives from competing effects.

Efficient, eco-friendly production of fine chemicals

The chemical industry produces not just valuable vitamins, pharmaceuticals, flavours and pesticides, but often a large amount of waste, too. This is particularly true of pharmaceutical and fine-chemical production, where ...

Atomic-scale ping-pong

New experiments by researchers at the National Graphene Institute at the University of Manchester have shed more light on the gas flow through tiny, angstrom-sized channels with atomically flat walls.

Chameleon-inspired nanolaser changes colors

As a chameleon shifts its color from turquoise to pink to orange to green, nature's design principles are at play. Complex nano-mechanics are quietly and effortlessly working to camouflage the lizard's skin to match its environment.

Team develops flexible blue vertical micro LEDs

A KAIST research team has developed a technology that will advance the commercialization of micro LEDs. Professor Keon Jae Lee from the Department of Materials Science and Engineering and his team have developed a low-cost ...

Nanoscale 'crack-junctions' can speed up DNA sequencing

The time-consuming, expensive process of sequencing DNA molecules – a technology used to identify, diagnose and possibly find cures for diseases – could become a whole lot faster and cheaper as a result of a new nanofabrication ...

Nanowires for sustainable, renewable energy

Recent studies have revealed that semiconductor nanowires offer unique advantages for a wide range of applications. An EU-funded project is breaking new ground in the move towards sustainable and efficient energy harvesting ...
