Many oxychalcogenide NLO materials have now been designed and synthesized through chemical substitution engineering. Herein, the crystal structures structure-property relationships of recent oxychalcogenides with IR properties are reviewed along how to integrate best features different anion groups. For more details, see Review by H. Yu et al. (DOI: 10.1002/chem.202203597).

Conversional hydrotreating catalysts mostly use Ni-promoted MoS2 as active sites. Modifying conventional hydrotreating catalyst surface of MoS2 by selectively introducing carbon atom into catalyst crystal structure can lead to an improved electronic property, increased capability of hydrogen adsorption and dissociation. Such process will effectively increase catalyst hydrogenation activity and ...

The performance of metamaterial is limited to a designed narrow band due its resonant nature, it highly desirable incorporate active inclusions in metamaterials extend the operation bandwidth. This review summarizes development realizing tunability electromagnetic response incorporated with nematic liquid crystal (LC). From rigorous comparison, found that anisotropic property LC essential predi...

Variational monotone recurrence relations arise in solid state physics as generalizations of the Frenkel-Kontorova model for a ferromagnetic crystal. For such problems, Aubry-Mather theory establishes the existence of “ground states” or “global minimizers” of arbitrary rotation number. A nearest neighbor crystal model is equivalent to a Hamiltonian twist map. In this case, the global minimizers...

Aspartame (L-alpha-aspartyl-L-phenylalanine methyl ester) is a dipeptide sweetener about 200 times as sweet as sugar. It exists in crystal forms such as IA, IB, IIA, and IIB, which differ in crystal structure and in the degree of hydration. Among these, IIA is the most stable crystal form, and its crystal structure has been well determined (Hatada et al., J. Am. Chem. Soc., 107, 4279-4282 (1985...

the radiophotoluminescence property of some materials makes it possible to use them for dosimetry purposes. the silver activated metaphoshate glass 1 as an rpl dosimeter when exposed to x. or y radiations , forms fluorescent centers with long lived states ( metastate ). the silver ions (ag+) in unirradiated state produces vacancies when energy is supplied by irradiation the release of electrons...

objectives: herbal medicine is known as a valid alternative treatment. salvia reuterana, which has been used in the iranian traditional medicine, is mostly distributed in the central highlands of iran. salvia reuterana is a medicinal herb with various therapeutic usages. the aim of the present review is to take account of pharmacological properties of salvia reuterana. materials and methods: th...

We prove a Chevalley formula for anti-dominant weights in the torus-equivariant K -group of semi-infinite flag manifolds, which is described explicitly terms Lakshmibai-Seshadri paths (or equivalently, quantum paths); contrast to dominant our previous paper [17] , has significant finiteness property. Based on geometric results established proof representation-theoretic, and follows from certain...
