Metasurfaces enable improved optical lens performance

Nanowerk.com - 9 февраля, 2018 - 18:58
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.

Controlling the kinetics of ion-capturing/ion-releasing regimes in liquid crystals by means of nanoparticles

Nanowerk.com - 9 февраля, 2018 - 18:39
New work describes how to control the kinetics of ion-capturing/ion-releasing regimes in liquid crystals by means of nanoparticles. Various types of nanomaterials and alignment layers are considered major components of the next generation of advanced liquid crystal devices. While the steady-state properties of ion-capturing/ion-releasing processes in liquid crystals doped with nanoparticles and sandwiched between alignment films are relatively well understood, the kinetics of these phenomena remains practically unexplored.

Ultra-efficient removal of carbon monoxide using gold nanoparticles on a molecular support

ScienceDaily.com: Nanotechnology News - 9 февраля, 2018 - 18:07
Researchers have developed a way to mount gold nanoparticles on a molecular support known as a polyoxometalate (POM). They successfully applied this to realize nearly 100% conversion of carbon monoxide (CO) over a wide temperature range, demonstrating stable performance over long periods of time. They showed how traces of water uniquely contribute to the catalyst's function, promising insight into catalysis and potential application to exhaust gas and room air purification.

A super resolution view of chemical reactions

Nanowerk.com - 9 февраля, 2018 - 17:16
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.
