Scientists use 2D h-BN nanosheets as the planar-alignment agent in a liquid crystal device to improve its optical transmission

NanoWerk.com - Thu, 03/14/2019 - 12:16
Researchers report an interesting phenomenon of two-dimensional (2D) hexagonal boron nitride (h-BN)-induced planar-alignment of a nematic liquid crystal and the subsequent optical and electro-optical effects. Liquid crystals (LCs) are optically anisotropic materials, and they are widely used in electro-optical display technology, known as liquid crystal displays (LCDs). Understanding the alignment phenomena of a nematic LC on a surface remains an important area of research, as the alignment process determines the LC's molecular orientation and conformation - which influence the LC's optical and electro-optical characteristics in LCDs.

Bottom-up assembled chiral meta-molecules

NanoWerk.com - Thu, 03/14/2019 - 05:26
Inspired by chiral molecular structures, scientists are developing strategies to build artificial chiral materials by mimicking natural molecular structures using functional materials. Specifically, metal nanomaterials exhibit tailorable optical properties upon excitation of surface plasmons and become one of the most promising components to realize chiral optical metamaterials. New work provides a macroscopic model to understand the origin of chirality because the structures of the chiral meta-molecules are observable under a microscope and also the optical chirality is several orders of magnitude stronger than the intrinsic chirality of organic molecules.

X-ray analysis of carbon nanostructures helps material design

NanoWerk.com - Thu, 03/14/2019 - 01:34
Nanostructures made of carbon are extremely versatile: they can absorb ions in batteries and supercapacitors, store gases, and desalinate water. How well they cope with the task at hand depends largely on the structural features of the nanopores. A new study has now shown that structural changes that occur due to morphology transition with increasing temperature of the synthesis can also be measured directly -- using small-angle X-ray scattering.
