Structural Characterization of the Cu2(Se,Te)3-(Ga,In)2(Se,Te)3 Semiconducting Systems

Many contributions have been reported in the literature about the synthesis and characterization of chalcopyrite-related Inand Ga-rich ordered defect compounds of the ternary systems: Cu-In-Se, Cu-In-Te, Cu-Ga-Se and Cu-GaTe. Particular interest has been paid to the compounds that can be derived from the formula CuN-3InN+1Se2N, where N=4, 5, 6, 7, 8 and 9, because some of these materials have a...

Solid state polyselenides and polytellurides: a large variety of Se-Se and Te-Te interactions.

A large variety of different interactions between the chalcogen atoms, Q, occur in the solid state structures of polyselenides and polytellurides, including both molecular and infinite units. The simplest motifs are classical Q(2)(2-) dumbbells and nonlinear Q(n)(2-) chains (n = 3, 4, 5, ..), e.g. found in alkali metal polychalcogenides. In addition, nonclassical so-called hypervalent motifs ex...

Factores Que Contribuyen Al Incumplimiento De Hipoglucemiantes Orales Entre Los Pacientes Ambulatoriales Diabéticos Tipo 2 En El Suroeste De Nigeria

www.pharmacypractice.org (ISSN: 1886-3655) 163 ABSTRACT Objective: The overall goal of the study was to evaluate the probable reasons for patients’ nonadherence to prescribed oral hypoglycemic medications in an ambulatory care setting in Nigeria with a view to identifying points for necessary intervention to improve adherence and treatment outcomes. Also, the recommended non-drug management opt...
