By studying metallic glasses under extreme pressures, scientists have uncovered rules that could help in the development of new varieties.

A material made of buckyballs and potassium ions becomes superconducting at -170°C when irradiated with pulses of infrared light.

Eight-armed nanoparticles of Au and Pd, which combine the catalytic and plasmonic capabilities of each element, could speed up chemical reactions.

Scientists have uncovered evidence of electronic nematicity as a universal feature in cuprate high-temperature superconductors.

Tetrahedral cages made from DNA can be used to arrange nanoparticles in a way that mimics the crystalline structure of diamond.

A new technique can create nearly two-dimensional nanosheets from compounds that do not naturally form such thin materials.

For the first time, scientists have observed 'polar vortices', which could be the electrical cousins of magnetic skyrmions, in a ferroelectric material.

New CVD growth process can produce high quality wafers of single crystal graphene fast.
