Borophene shines alone as 2-D plasmonic material

An atom-thick film of boron could be the first pure two-dimensional material able to emit visible and near-infrared light by activating its plasmons, according to Rice University scientists.

Clothing fabric keeps you cool in the heat

(Phys.org)—Researchers have designed a thermal regulation textile that has a 55% greater cooling effect than cotton, which translates to cooler skin temperatures when wearing clothes made of the new fabric. The material ...

Researchers study the surfaces of ceria nanoparticles

At Karlsruhe Institute of Technology (KIT), scientists have studied ceria nanoparticles with the help of probe molecules and a complex ultrahigh vacuum-infrared measurement system and obtained new insights into their surface ...

Stretching to perfection of 2-D semiconductors

Compressing a semiconductor to bring atoms closer together or stretching it to move them farther apart can dramatically change how electricity flows and how light is emitted. Scientists found an innovative way to compress ...

Graphene water filter turns whisky clear

Previously graphene-oxide membranes were shown to be completely impermeable to all solvents except for water. However, a study published in Nature Materials, now shows that we can tailor the molecules that pass through these ...

Semiconductors with an aligned interface

The electronic characteristics of an interface between two wide bandgap semiconductors are determined by researchers at KAUST: an insight that will help improve the efficiency of light-emitting and high-power electronic devices.

Graphene tests set for zero-G flight

After a long summer of hard work in the laboratories, researchers in the Graphene Flagship are ready for two experiments this week, testing graphene technologies for space-related applications in collaboration with the European ...

Cool textiles to beat the heat

Air-conditioned buildings bring welcome relief to people coming in from the heat. But creating that comfort comes with a cost to our wallets and the environment in the form of increased energy bills and greenhouse gas emissions. ...

Better, bolder printing with silicon nanostructures

From textbooks to artwork to newspapers, printed items are a part of our everyday life. But the ink used in today's printers are limited in colors and resolution. Now in a new study in ACS' journal Nano Letters, scientists ...

Graphene performs under pressure

Scientists at The University of Manchester have fabricated highly miniaturised pressure sensors using graphene membranes which can detect minute changes in pressure with high sensitivity, over a wide range of operating pressures.

The flat and the curious

The remarkable properties of 2-D materials—made up of a single layer of atoms—have made them among the most intensely studied materials of our time. They have the potential to usher in a new generation of improved electronics, ...

Characterisation of the structure of graphene

Graphene, the world's first two-dimensional material, is many times stronger than steel, more conductive than copper, lightweight, flexible and one million times thinner than a human hair.
