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 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 ...

Engineers develop recipe to dramatically strengthen body armor

According to ancient lore, Genghis Khan instructed his horsemen to wear silk vests underneath their armor to better protect themselves against an onslaught of arrows during battle. Since the time of Khan, body armor has significantly ...

Magnetoresistance ratio enhancement in Heusler-based alloy

Magnetic field sensors can enhance applications that require efficient electric energy management. Improving magnetic field sensors below the picoTesla range could enable a technique to measure brain activity at room temperature ...
