A new slant on semiconductor characterization

Method analyzes non-uniform conductors with a magnetic field.

Using hydrogen-treated graphene nanofoam to enhance lithium ion batteries

Scientists have found that lithium ion batteries operate longer and faster when their electrodes are treated with hydrogen.

Single-layer NbSe2, a true 2D superconductor

An international team has demonstrated the coexistence of superconductivity and charge density wave order in a single layer of NbSe2, a model transition metal dichalcogenide metal.

Researchers fabricate a metamaterial using a lotus leaf as a template

Unique surface structures play a vital role in metamaterials, and scientists have begun looking to nature itself for patterned surfaces from which to draw inspiration. Using a lotus leaf as a template, the new substance is capable of almost total absorption of light across the entire visible spectrum.

Harvesting more energy from photons

Quantum process increases the number of electrons produced when light strikes a metal-dielectric interface.

Trampolining water droplets (w/video)

Researchers have shown that it is, in principle, possible to develop materials that are literally allergic to ice and water. To do so, they first taught tiny water droplets how to trampoline.

Novel 'crumpling' of hybrid nanostructures increases SERS sensitivity

By 'crumpling' to increase the surface area of graphene-gold nanostructures, researchers have improved the sensitivity of these materials, opening the door to novel opportunities in electronics and optical sensing applications.
