By mixing borax with hot water and allowing it to cool, kids can observe the formation of intricate and beautiful crystal structures. This experiment is an excellent illustration of how temperature changes affect the solubility of substances. Luckily, you don’t need expensive or unique supplies to...
When nc < 1016 cm−3, τs−1 is insensitive to nc, which is because both |g~↑↓|2¯ and DS are determined by e-ph transitions around the band edge. In “Methods” section, we have proven that at the low density limit, since carrier occupation satisfies Boltzmann ...

Disordered structures such as liquids and glasses, grains and foams, galaxies, etc. are often represented as polyhedral tilings. Characterizing the associated polyhedral tiling is a promising strategy to understand the disordered structure. However, since a variety of polyhedra are arranged in complex ...
The structures suggest that the T-loops do not have a rigid structure and that they may be flexible in solution. The presence of a turn of 310 helix in the middle of the T-loop suggests that secondary structure could form when it interacts with soluble receptor enzymes. Co-crystals of G...
Among the physicochemical cues in the cellular microenvironment that orchestrate cell processes, the different levels of curvature in the extracellular matrix and intrinsic to the tissues play a pivotal role in the spatiotemporal control of key cellular
rotations. In particular, the bulk halide perovskite such as CsPbBr3, which possesses one of the simplest halide perovskite structures, is a good benchmark system to understand the fundamental physical mechanisms but already presents several outstanding questions. First, what is the intrinsicτsof ...
Dehumidifiers remove excess moisture from the air, preventing mold, mildew and damage to home structures and furniture. These devices can mitigate allergy symptoms related to dust mites, fungi and mold by maintaining a drier environment less conducive to these allergens. They can also improve breathin...
