Degenerate diffusion plays an important role in the interface motion of complex structures. The degenerate Cahn-Hilliard equation is a widely used model for single layer structures. It has been ...

Researchers have developed a new type of bifocal lens that offers a simple way to achieve two foci (or spots) with intensities that can be adjusted by applying external voltage. The lenses, which use ...

In certain instances, direct access to a structure being studied may not be possible due to mechanical constraints, such as device packaging or limitations related to the samples themselves. To ...

A team led by researchers at the University of Cambridge in the United Kingdom has demonstrated layer-by-layer (LbL) vapor-phase-based growth of halide perovskites, specifically cesium, lead, bromine ...

Researchers developed a bifocal lens based on two layers of liquid crystal (LC) structures. The intensities for the two focal lengths can be easily adjusted by applying external voltage. WASHINGTON — ...
