Crystalline materials news, August 2017

Using electron microscopy, scientists have discovered that silica nanoparticles form quasicrystals as they grow and evolve.

Scientists have used machine learning to gain insight into the physical structures associated with specific properties of metals and alloys.

A composite of a polymer and a 2D material can store energy at operating temperatures well above current commercial polymers.

A newly discovered collective rattling effect in a crystalline semiconductor blocks most heat transfer while preserving high electrical conductivity.

For the first time, scientists have observed the formation of a crystal gel with particle-level resolution.

Scientists have made the first observation of nanocrystals rapidly forming superlattices while they are themselves still growing.

Scientists have predicted and created new 2D electrocatalysts able to extract hydrogen from water with high performance and low cost.

Defects in the structure of topological insulators can cause electron transport to occur in the bulk rather than just at the surface.

Naturally occurring fatty acids that cover insect wings can be used to form ‘mechanobactericidal’ coating.

The granules in copper can never fit together perfectly and so are forced to rotate, causing an unexpected level of surface roughness.

By combining tools from chemistry, mathematics, physics and materials science, researchers have found a way to identify novel topological insulators.

Quality control tool for MoS2 promises improved 2D material for next generation electronics and optoelectronics.

Reducing oxygen in some nanocrystalline alloys may improve their strength and durability at elevated temperatures.
