Holographic polymer films have emerged as a versatile platform where interference patterns are stored via photopolymerisation in photosensitive matrices. When these films are integrated with liquid ...

The addition of buckyballs or carbon nanotubes to nematic liquid crystals changes their properties and makes them low-cost alternatives for holographic and image processing applications, according to ...

Preliminary studies of the highly polar organic molecule DIO revealed a mysterious liquid crystal phase between the nematic and ferroelectric nematic phases. X-ray diffraction studies showed that this ...

In physics, some waves behave in a surprising way: instead of spreading out and fading, they hold their shape as they travel at constant speeds. These unusual waves, called solitons, have interested ...

A big picture window that turns opaque at the flick of a switch, giving those inside instant shade and absolute privacy. A wall clock, no thicker than a pane of safety glass, that flashes the hour ...

Physicists from Case Western Reserve University, Tufts say they’ve remotely altered microscopic surface; could lead to applications for microchips, or ‘liquid tools’ Physicists at Case Western Reserve ...

Scaling up perovskites for potential widespread use in solar cells has been a challenge due to arising defects. Yi Yang, postdoctoral fellow; Ted Sargent, Lynn Hopton Davis and Greg Davis Professor of ...
