Scientists from Los Alamos National Laboratory, Rice University and Northwestern University have worked towards enhancing the application of perovskite crystals in the booming solar power industry. This initiative was carried out by modifying their crystal manufacturing technique and producing a new variety of two-dimensional layered perovskite with exceptional strength and increased power transformation capability unlike the material’s earlier conversion efficiency.
Glasses are amorphous solids, meaning that they are neither fluids nor crystals. They are one of the greatest puzzles of condensed matter physics. How glass is formed has been a matter of debate over years. Is it due to the freezing of thermal motion of some regions? Or is it due to the clusters or particles which do not fit to produce a crystal?
The two key physical attributes that contribute to the brightness and colorfulness of a butterfly wing have been discovered by a team of scientists by visualizing its internal nanostructure.
For the first time, researchers from the RIKEN Center for Advanced Photonics (RAP), have successfully induced permanent alterations in the polymer conformation using a terahertz laser, thereby providing it with an increased crystallization pattern.
There is a wide range of applications of crystals in various fields like physics, engineering, gemology or metallurgy.
Materials that react to dynamic loading can provide better protection to military convoys, reduce vibrations in vehicles, and can make buildings relatively safer during earthquakes.
Materials researchers at North Carolina State University have developed a new technique to deposit diamond on the surface of cubic boron nitride (c-BN), integrating the two materials into a single crystalline structure.
Pure calcite is a weak, fragile mineral that is generally present in chalk. As such, construction engineers do not prefer to use this mineral as a building material. However, if calcite is reinforced by a factor of two or more, similar to the way a mollusk has done to protect itself from predators through an evolutionary process, it could be a suitable building material.
UC San Diego chemists have produced an ‘adaptive protein crystal’ that possesses a unique counterintuitive property, which could be useful in designing body armors and soles of running shoes. When the material is stretched in a single direction, it thickens in the perpendicular direction instead of thinning, as seen in common materials, and when the material is compressed in one dimension, it reduces in the other dimension instead of expanding and becomes thicker during the process.
When an assembly of microgel particles includes one particle that's significantly larger than the rest, that oversized particle spontaneously shrinks to match the size of its smaller neighbors. This self-healing nature of the system allows the microparticles to form defect-free colloidal crystals, an unusual property not seen in systems made up of “hard” particles.
