Reaction pathway investigations of the solvothermal preparation of nanocrystalline Culn1xGa xSe2 in triethylenetetramine reveal the early formation of a previously unreported CU2-xSe(S) intermediate. Over 24 hours, this reacts with In and Se species to form CulnSe2(s). If Ga is present, the reaction proceeds over an additional 48 hours to form Culn1xGa xSe2. Adding ammonium halide salts reduces...
A wide range of organozinc substrates may be oxidized in the presence of catalytic copper to give carbon-carbon bonds in high yield.
Controlling the morphology of organolead halide perovskite crystals is crucial to a fundamental understanding of the materials and to tune their properties for device applications. Here, we report a facile solution-based method for morphology-controlled synthesis of rod-like and plate-like organolead halide perovskite nanocrystals using binary capping agents. The morphology control is likely du...
While infrared upconversion imaging using halide nanoparticles are so common the search for a very efficient halide free upconverting phosphors is still lacking. In this article we report Gd2O2S:Yb/Er,YbHo,YbTm systems as a very efficient alternative phosphors that show upconversion efficiency comparable or even higher than existing halide phosphors. While the majority of rare earth dopants pro...
A strong anodic peak observed in cyclic voltammetry measurements of palladium electrodes when adding glucose to chloride containing (0.1 M) slightly acidic (pH 5.3) unbuffered media was studied in detail. The peak was highly sensitive to glucose concentration (5–20 g/L). Experiments were conducted by variation of pH (1–13) and chloride concentration (0.5–50 g/L) of the medium over a wide range,...
BACKGROUND Mutations in the cystic fibrosis transmembrane regulator (CFTR) gene can reduce function of the CFTR ion channel activity and impair cellular chloride secretion. The gold standard method to assess CFTR function of ion transport using the Ussing chamber requires a high number of airway epithelial cells grown at air-liquid interface, limiting the application of this method for high thr...
Silicon is as an essential element for crops and an important food source for the growth of rice plant. If no adequate replacement for this element, plants are faced with a shortage of silicon causing serious eating disorder and instability in plant resistance to pests. This research was done to investigate the effect of silicon on growth, yield and tolerance to rice stem borer in Tarom Hashemi...
