Hydrogen is the first element in theperiodic table, meaning it has anatomic numberof 1 or 1 proton in each hydrogen atom. The name of the element comes from the Greek wordshydrofor "water" andgenesfor "forming," since hydrogen bonds with oxygen to form water (H2O). Robert Boyle produced ...
Corrosion degrades metals through complex microscopic processes that traditional methods often fail to capture. In situ transmission electron microscopy (TEM) bridges this gap by providing real-time, atomic- and nanoscale imaging of oxidation and corrosi
The one preferred embodiment the small hydro-carbon molecule methane, (CH4), is used as a buffer gas to collisionally relax the pumped 7p 2P3/2 electronic level to the 7p 2P1/2 electronic level, enabling a CW population inversion density between the 8s 2S1/2 upper laser level and the ...
To avoid interaction between periodicity-induced images, a vacuum of 20 Å along the z-direction is maintained in the supercell. To sample the first Brillouin zone for non-spin polarized self-consistent and density of states (DOS) calculations, the K-point grids of 3 × 3 × 1 and 5 ...
The extraction of atomic-level material features from electron microscope images is crucial for studying structure-property relationships and discovering new materials. However, traditional electron microscope analyses rely on time-consuming and complex human operations; thus, they are only applicable to ima...
Improved non-local electron thermal transport model for two-dimensional radiation hydro- dynamics simulations. Phys. Plasmas 22, 082308 (2015). 68. Hu, S. X., Militzer, B., Goncharov, V. N. & Skupsky, S. First-principles equation-of-state table of deuterium for inertial confinement fusion...
It readily dissolves in concentrated hydrochloric acid, perchloric acid, or hydroiodic acid, forming the Pu3+ ion. Plutonium exhibits four ionic valence states in ionic solution. The metal has the nuclear property of being readily fissionable with neutrons. A relatively large piece of plutonium ...
Understanding the dynamical processes that govern the performance of functional materials is essential for the design of next generation materials to tackle global energy and environmental challenges. Many of these processes involve the dynamics of indiv
The plane-wave periodic DFT method in the Vienna ab initio simulation package was used to carry out this work52. The electron ion interaction was described with the projector augmented wave method53. The electron exchange and correlation energy was treated within the generalized gradient approximation...
