In material chemistry, the coordination number is generally defined as the number of atoms attached to central ion. In a solid-state, it can be defined as the number of atoms attached to another atom. For different unit cells, the coordination number is also different...
When people refer to "amplifiers," they're usually talking about stereo components or musical equipment. But this is only a small representation of the spectrum of audio amplifiers. There are actually amplifiers all around us. You'll find them in televisions, computers, portable CD players and ...
due to their highly tunable spin-orbit fields and intriguing interplay with lattice symmetry. Here, we perform first-principles calculations to determine the spin relaxation time (T1) and ensemble spin dephasing time ({T}_{2}^{*}) in a prototype halide perovskite, CsPbBr3. To accurately captur...
First, we find that at a very low T - 4 K, only acoustic modes (A1-A3) contribute to spin and carrier relaxation. This is simply because the optical phonons are not excited at such low T (corresponding kBT ~ 0.34 meV much lower than optical energy ≳ 2 meV). At T ...
The grids have a lattice of lead wires that channel current to a tab at the top of the grid. This alternating grid setup is known as an element, and each battery cell contains one element.Each element is placed into one of the battery's individual cells, with the strap of one cell ...
World of energy A brief history of energy Find out more Potential energy and kinetic energy Although there are many kinds of energy in the world, they all fall into two broad categories:potential energyandkinetic energy. When energy is stored up and waiting to do things, we call it potential...
Fermi liquid behavior was usually attributed to spin fluctuations (see for example9). While such a correction is expected at very low temperature, it is hard to see how they can play a role in our temperature of interest given the small amplitude of the exchange energy (See Supplementary ...

Here we uncover the physicochemical underpinnings of how evolutionarily conserved compositional biases influence the phase behaviour of PLCDs. We interpret our results in the context of the stickers-and-spacers model for the phase separation of associative polymers. We find that tyrosine is a stronger...
