Physicists show novel Mott state in twisted graphene bilayers at 'magic angle'

The physicists show that the Mott state in graphene bilayers favors ferromagnetic alignment of the electron spins, a phenomenon unheard of in conventional Mott insulators, and a new concept on the novel insulating state observed in twisted graphene bilayers.

Photovoltaic nanotubes could improve solar power and imaging technology

Physicists discovered a novel kind of nanotube that generates current in the presence of light.

Controlling textures in single crystal soft materials

A new study demonstrates a method to create single crystal texture in a self-assembled soft material.

Developing a new type of refrigeration via force-driven liquid gas transition

A research team made a groundbreaking discovery in the quest to replace hydrofluorocarbons in refrigeration systems with natural refrigerants such as water and alcohol. Their study involved carrying-out a liquid-to-gas phase transition via a nanosponge, a soft, elastic material equipped with nanopores.

Real-time analysis of metal-organic framework adsorption behavior

Researchers have developed a technology to analyze the adsorption behavior of molecules in each individual pore of a metal organic framework (MOF).

A quick liquid flip helps explain how morphing materials store information

Experiments with x-ray lasers reveal in atomic detail how two distinct liquid phases in these materials enable fast switching between glassy and crystalline states that represent 0s and 1s in memory devices.
