CrystalstructurewiththeFCClattice We consider four structures with the FCC lattice. TheNaCl(orrocksalt)structure In this structure, which is also known as the alkali halide or rocksalt structure (碱金属卤化物或者称为岩盐结构), each point of the FCC lattice is assigned a basis of one unit of ...
Crystal, any solid material in which the component atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. Crystals are classified in general categories, such as insulators, metals, semiconductors, and molecu

Crystal - Bonds, Structure, Lattice: The properties of a solid can usually be predicted from the valence and bonding preferences of its constituent atoms. Four main bonding types are discussed here: ionic, covalent, metallic, and molecular. Hydrogen-bond
摘要: PROBLEM TO BE SOLVED: To provide a crystal oscillator having a structure that secures mechanical fixation and electrical connection and reduces an adverse effect which a stuck conductive adhesive imposes on the electrical characteristic of the crystal resonator....
Diamonddoes not only draw nice pictures of molecular and crystal structures like most of its competitive programs do. It offers an extensive set of functions that let you easily model any arbitrary portion of a crystal structure from a basic set of structural parameters (cell, space group, atomi...
Crystal structure of 2-chloro-1,3-(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium tetrakis(3,5-trifluoromethylphenyl)borate The salt compound presented is an example of a 2-chloro imidazolidinium structure where the formerly carbene carbon has a trigonal–planar geometry. The ti... ...
Crystal structure of Q1-complexed OfHex1 and docked structure of Q1-complexed HsHex. (a). The superimposition of the unliganded-OfHex1 andQ1-complexed OfHex1. Residues of unliganded-OfHex1 andQ1-complexed OfHex1 are shown in white and blue, respectively.Q1is shown in green. The hydrogen...
The assembly is stabilized by a mix of arylamide stacking interaction, hydrogen bonding and hydrophobic forces. The omnitruncated octahedra tessellate to form a cubic crystal. These findings may provide an important step towards the design of nanostructured particles resembling spherical viruses....
