Multilevel polarization switching in ferroelectric thin films

Ferroelectric materials have found widespread use in everyday technology mainly owing to their electric polarization that can be switched between two distinct states. Overcoming the binary limit of ferroelectrics in order ...

Scientists synthesize new, ultra-hard material

Russian scientists have synthesized a new ultra-hard material consisting of scandium containing carbon. It consists of polymerized fullerene molecules with scandium and carbon atoms inside. The work paves the way for future ...

Group develops world's first DMA for hard materials

Recently, the Li Faxin Research Group of Peking University College of Engineering developed the world's first dynamic mechanical analyzer (DMA) suitable for hard materials (metals, ceramics, etc.). The instrument is based ...

Automatically steering experiments toward scientific discovery

In the popular view of traditional science, scientists are in the lab hovering over their experiments, micromanaging every little detail. For example, they may iteratively test a wide variety of material compositions, synthesis ...

Scientists discover new approach to stabilize cathode materials

A team of researchers led by chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery ...

Machine learning boosts the search for 'superhard' materials

Superhard materials are in high demand in industry, from energy production to aerospace, but finding suitable new materials has largely been a matter of trial and error based on classical materials such as diamonds. Until ...
