Magic angle in superconducting graphene not quite so magical

Scientists have discovered that the magic angle at which two layers of graphene become superconducting is slightly wider than originally thought.

Silver helps borophene grow to unprecedented lengths

Using a silver substrate and molecular-beam epitaxy , scientists were able to grow elongated, hexagon-shaped flakes of the 2D material borophene.

New model reveals role of hopping electrons in high-temperature superconductors

A new model suggests that high-temperature superconductivity in cuprates arises when electrons hop from atom-to-atom in a particular pattern.

New process makes ceramics less brittle in a flash

A new process termed ‘flash sintering’ can help overcome the brittle nature of ceramics and make them more ductile and durable.

Quantum loop leads to room-temperature topological magnet

Researchers have found that a crystal made of cobalt, manganese and gallium is a room-temperature topological magnet that hosts quantum loops.

Molybdenum helps produce better transparent coating for touchscreens

Researchers have found that doping indium oxide with molybdenum rather than tin doubles the conductivity of this transparent conductor.

Organic semiconductors need to stay hydrated during doping

A Lewis acid offers an effective way to change the electrical properties of certain organic semiconductors, but only in the presence of water.

Novel soft material carries out logic functions when touched

A silicone polymer embedded with temperature-sensitive dyes and liquid metal wires can carry out simple logic functions in response to touch.

None more black

Coating chlorine-etched aluminum foil with carbon nanotubes created a material that is 10 times blacker than anything previously reported.

Halide perovskites are troubled by dislocations

Crystallographic dislocations can impact the ability of halide perovskites to hold energy derived from light in the form of excited electrons.

Tiny material protrusions generate static electricity when rubbed together

A new model shows how rubbing two objects together produces static electricity by bending tiny protrusions on the surface of the objects.

New finding expands material choice for organic solar cells

Only around 1% of the surface area of the electrodes in organic solar cells needs to be electrically conductive for them to be fully effective.
