Metasurfaces enable improved optical lens performance

Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now engineers have developed a new theory that solves the problem using a single thin lens comprised of gradient index materials and metasurface layers to properly direct the light.

Stacking on the graphene

Researchers have fabricated two types of trilayer graphene with different electrical properties.

Water-soluble warped nanographene and its application for photo-induced cell death

Researchers have introduced 'warped nanographene', which is soluble in a broad range of solvents while maintaining its photophysical properties.

Few-layer tellurium as a promising successor of black phosphorus

Scientists have theoretically predicted few-layer alpha-Tellurium to be a promising elementary semiconductor with extremely high carrier mobility, layer-tunable bandgap, strong light absorption, large strength and good environmental stability.

A super resolution view of chemical reactions

Researchers have demonstrated, using a super resolution microscopic technique, how to follow chemical reactions taking place in very small volumes. The method of analysis is the first to make it potentially possible to observe reactions not only inside living cells, but even within individual organelles, such as cell nuclei.
