Few-layer antimonene decorated microfiber improves optical modulation communication with enhanced long-term stability

Tue, 03/27/2018 - 04:08
Researchers have used a few-layer antimonene nanosheet to demonstrate all optical modulation in optical signal processing. To utilize the saturable absorption property of few-layer antimonene, antimonene-decorated microfiber was employed as an optical saturable absorber that can allow for passive mode-locking, Q-switching and all-optical thresholding at the telecommunication band. These results may provide guidance for the application of antimonene and other Group VA mono-elemental 2D materials in ultra-short pulse generation and all optical thresholding with enhanced long term stability.

Photostriction of molecular 2D nanosheet

Tue, 03/27/2018 - 04:05
In new work employing the photostrictive effect, researchers have fabricated a flexible two-dimensional (2D) charge transfer molecular (sub-nanometer) nanosheet and observed a sizeable photostrictive effect of 5.7% with fast, sub-millisecond response; this is higher than that of some conventional ferroelectronics and polar semiconductors. This photostrictive effect arises from excess charge carriers induced lattice dilation and conformation change, which is higher than that of some conventional ferroelectronics and polar semiconductors.

DNA origami as a novel avenue for creating next-generation optical voltage sensing nanodevices

Mon, 03/26/2018 - 05:30
Over the past few decades, researchers have developed various optical voltage sensing probes in order to overcome the highly invasive nature of electrode-based techniques. These voltage sensing mechanisms can be hampered by some combination of limitations including low sensitivity, slow kinetics, or heavy capacitive loading. This has motivated a group of researchers to explore DNA nanotechnology for developing novel optical voltage sensing nanodevices that convert a local change of electric potential into optical signals.They now report that a voltage can be read out in a nanopore with a dedicated Förster resonance energy transfer (FRET) sensor on a DNA origami.
