Indium is a heavy metal belonging to group IIIa. It is believed that indium may interfere with iron metabolism from the sites of absorption, transportation, utilization and storage in the cells. The present investigation was established to study and compare the binding of iron and indium to human apo-transferrin (apo-tf). Pure human apo-tf was used and the binding activity of iron and indium, a...

A novel one-pot method was developed for the synthesis of the title compounds starting from 4-chloro-1-aryl-1-butanones 1, phosphorus trichloride and acetic acid. The end products 2 were obtained in 20-94% yield. The cyclization step under acidic conditions probably occurs as a result of anchimeric assistance of the phosphonic acid group.

Indium belongs to Group III A in the periodic table and it is mainly used in the making of thin-film transistor liquid crystal displays (LCDs) for television screens, portable computer screens, pocket telephone displays and video monitors, mainly through the utilization of indiumtin oxide (ITO). ITO is a sintered alloy containing a large portion of indium oxide and a small portion of tin oxide....

In this paper, we present our ab-initio study on energy configurations, minimum energy path (MEP), and migration energy for neutral indium diffusion in a uniaxial and biaxial tensile strained {100} silicon layer. Our abinitio calculation of the electronic structure allowed us to figure out transient atomistic configurations during the indium diffusion in strained silicon. We found that the lowe...

A sensitive and simple method for the determination of trace amounts of indium in water samples by graphite furnace atomic absorption spectrometry (GFAAS) after coprecipitation with chitosan was investigated. Indium was quantitatively preconcentrated from water samples by coprecipitation with chitosan at pH 7.0-9.0. The coprecipitant was easily dissolved with acetic acid, and indium in the resu...

A simple, chemoselective transfer hydrogenation of aryl aldehydes with the aid of Amberlite((R)) resin formate (ARF), a stable H-donor, in the presence of catalytic ruthenium trichloride is described. Aromatic aldehydes and 1,2-diketones are reduced efficiently and selectively, while aryl ketones remain unchanged. Several other potentially reducible groups attached to the aromatic moiety are un...
