Structure Crystals can be grown under moderate conditions from all 92 naturally occurringelementsexcept helium, and helium can be crystallized at low temperatures by using 25 atmospheres of pressure.Binarycrystals are composed of two elements. There are thousands of binary crystals; some examples are ...
In spite of their low strength, these forces can still be important in some solids; for example it is an important factor in determining the structure of many polymeric solids. Many common polymers consist of long molecular carbon chains with strong bonds joining the atoms in the chain, but ...
The most common crystal structure with the SC lattice is the CsCl structure. In this structure the basis consists of two atoms (one molecule of CsCl) with Cs at(0,0,0)and Cl ata(1/2,1/2,1/2)(or vice versa), where a is the cubic lattice constant. This structure is shown in fol...
Crystal Structure Data of Inorganic Compounds. Part b3: Key Elements S, Se, Te Summary This document is part of Subvolume C2 'Key Elements: P, As, Sb, Bi' of Volume 7 'Crystal Structure Data of Inorganic Compounds' of Landolt-Brnstein - Group III Condensed Matter. AM Clark - 《Mineral...
Cordierite is characterized by excellent thermal shock and linear thermal expansion properties.It is specially suited for the strict cases, such as the carrier for the purification of vehicle exhaust emission and LSC's substrate.Up to now,cordierite has been doped with other elements to decrease the...
The co-doping elements deteriorated the luminescence intensity except the Al₂O₃ and Gd₂O₃. The PL characteristics of CaWO₄-Li₂WO₄-Eu₂O₃ phosphors have been compared to those of the alkali europium double molybdates (tungstates) of scheelite-related structure such as LiEu...
elements from the fourth column of the periodic table (germanium, tin, and lead)combinewith the chalcogenides from the sixth row to form good binary semiconductors such asgermanium telluride (GeTe) ortin sulfide (SnS). They have the sodium chloride structure, where each atom has six neighbours....
We determined the crystal structure of the Mamu-B*098:C14nef5 complex at a resolution of 1.76 Å (Table 1 and Supplementary Fig. 2). The overall structure of Mamu-B*098 was almost indistinguishable from that of other MHC class I molecules, which were characterized by two semisymmetrical...
The main chain atoms in the 209 residues of domain 1 of sPBP 5′ composing the common elements of secondary structure of penicillin-interacting proteins can be superimposed onto the PC1 β-lactamase fold (36) with an r.m.s. deviation of 2.7 Å and the TEM-1 β-lactamase (39) fold ...
1b). To create a möbiuson, we first apply a voltage of U ≈ 3.5 V and generate an extended fragment of a localized fibre-like structure with 180°-twisted n(r) across its width by local melting of the chiral LC using laser tweezers and then quenching back to the mesophase ...
