One-way roads for spin currents

24-May-2018

The spin is a type of angular momentum which is intrinsic to particles, grosso modo as if they were spinning on themselves. Particles can exchange their spin, and in this way spin currents can be formed in a material. Through years of research, scientists have learned how to control such spin ...

Microscale IR spectroscopy enabled by phase change materials and metasurfaces

16-May-2018

The mid-infrared is an interesting part of the electromagnetic spectrum that is composed of colours that cannot be seen by the human eye. Many chemical molecules resonate when illuminated by infrared light. This infrared resonance can then be used to identify or "fingerprint" the molecules. The ...

Scaling to new heights with gecko-inspired adhesive

12-Jan-2018

Some animals, such as geckos, can easily climb up walls and across ceilings. But currently, no material exists that allows everyday people to scale walls or transverse ceilings as effortlessly. Now, scientists report a dry adhesive that could someday make it easier to defy gravity. Geckos can ...

Sensing with a twist: A new kind of optical nanosensor uses torque for signal processing

18-Sep-2017

The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. As electronic devices get smaller, their ability to provide precise, chip-based sensing of dynamic physical properties such as motion become challenging to develop. An international ...
