synthesis of different selenaaromatic ring systems are presented. A number of selenaaromatic compounds and their nonconjugated analogs are indicated as reagents and catalysts for organic synthesis, as biological response modifiers of practical importance as pharmaceuticals, and as new materials for ...
The precise three-dimensional (out-of-plane (zenithal) and in-plane (azimuthal)) alignment control of LC materials is of great importance in applications for LC display panels as well as photonic and memory devices. In particular, achieving efficient azimuthal control is a key issue in photo...
p-type transparent conductive materials and spintronic applications. The possibility of promoting the wurtzite lattice, presenting a different symmetry with respect to the most stable and common zincblende structure, is explored. Homo- and heterojunctions to twin ZnO are discussed as a possible route ...
These results underlie elucidation of the characteristic and peculiar features of acid insertion into graphite. The physicochemical properties and practical applications of GIC and low-density carbon materials are analyzed. 展开 关键词: graphite intercalation compounds (GIC) binary GIC ternary GIC acids ...
Ion-exchange reactions, particularly with molten salts, are a convenient low temperature route to prepare new materials. Six different complex oxides (KTaO3, K2Ti4O4, NaAlSiO4, Na2Si2O5, β-NaAlO2 and K2Ge4O9) were reacted with different salts (NaCI, KCl, Na2SO4, NaNO3, LiCl and LiN...
