Physics at the edge

Condensed matter physicists take a step closer to building a graphene-based topological insulator.

Soon, air pollution could be measured by nanosensors on every street corner

The technology is already in use in western Sweden, and researchers and other interested parties hope that the sensor could soon be used in many broad contexts.

Won again he has - 'MXene Yoda' wins art competition

'Mxene Yoda' has been created from a SEM scan of oxidized 2-D V2CTx particles that show promise as electrode material for supercapacitors and batteries.

Researchers develop semi-liquid metal anode for next-generation batteries

The new anode could help create a safer high energy lithium metal battery.

Hybrid nanostructure steps up light-harvesting efficiency

A stepwise transfer of energy through the different components of the nanostructure boosts its response to light, showing promise for solar cell applications.

Octopus-inspired skin-adhesive sensors

Researchers demonstrate a facile, low-cost, scalable fabricating method for water-resistant and skin-adhesive wearable graphene-coated fabric sensors.

Scientists achieve first observation of three-dimensional quantum Hall effect

In this study, researchers discovered that the carrier density wave induced by electron-electron interaction is the key factor for the appearance of 3D quantum Hall effect. Electrons in such a system can travel freely between different energy bands, like boats traveling in vast ocean.
