Molecular motors run in unison in a metal-organic framework

ScienceDaily.com: Nanotechnology News - Mon, 03/18/2019 - 22:11
For molecular motors to be exploited effectively, they need to be able to operate in unison. However, integrating billions of these nanometre-sized motors into a single system, and getting them to operate in unison has proved to be quite a challenge. Organic chemists have now succeeded in integrating numerous unidirectional light-driven rotary motors into a metal-organic framework (a solid material with a 3D cage-like structure).

Antimonene-based all-optical modulator

NanoWerk.com - Fri, 03/15/2019 - 09:10
In recent years, all-optical modulators (AOMs) have attracted significant interests due to their low power consumption, broad bandwidth, and potential in all-optical fields. Among these, AOMs based on the high photothermal efficiency of antimonene, exhibit remarkable advantages for their large modulation depth, wide operating wavelength range, and easy implementation. Researchers demonstrated that an antimonene-based AOM was successfully utilized to actively Q-switch a fiber laser in a fully photonics domain and this actively modulated laser represented all-optically tunable output parameters, and easy time synchronization.
