Ultrawide bandgap gives material high-power potential

Researchers have found a way to grow a single crystalline layer of alpha-aluminum gallium oxide that has the widest energy bandgap to date - a discovery that clears the way for new semiconductors that will handle higher voltages, higher power densities and higher frequencies than previously seen.

Researchers develop hydrogen-bonded organic frameworks based electrochromic film

Researchers have developed an electrochromic hydrogen-bonded organic frameworks film with long cycle life, facile modification, easy recycling and regeneration prepared via electrophoretic deposition rapidly and facile.

A sharp new eye to view atoms and molecules

A new X-ray laser oscillator generates types of pulses that were never before possible. The pulses are stable, intense, and of ultrashort duration and have a well-defined wavelength. This ability opens new possibilities in experiments and research.

New metamaterial offers reprogrammable properties

Scientists have developed a metamaterial whose mechanical properties can be reprogrammed on demand and whose internal structure can be modified by applying a magnetic field.
