A speciation method was developed for the determination of inorganic indium compounds in the particulate matter of emissions and from the workplace, based on selective sequential extractions. The main inorganic indium compounds that are expected to be present in the atmospheric particulate matter involving the industrial production of indium and in the manufacture of indium compounds were separ...
OBJECTIVES The use of indium compounds, especially those of small size, for the production of semiconductors, liquid-crystal panels, etc., has increased recently. However, the role of particle size or the chemical composition of indium compounds in their toxicity and distribution in the body has not been sufficiently investigated. Therefore, the aim of this study was to examine the effects of p...
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....
Occupational exposure to indium compound particles has recently been associated with lung disease among workers in the indium-tin oxide (ITO) industry. Previous studies suggested that excessive alveolar surfactant and reactive oxygen species (ROS) may play a role in the development of pulmonary lesions following exposure to indium compounds. However, toxicity at the cellular level has not been ...
Allyl and 2-methylallyl indium compounds were prepared by salt metathesis starting from indium trichloride and a Grignard reagent. They are highly fluxional in solution and reveal coordination numbers of the indium atoms of four and five in the solid state.
Despite the increasing industrial use of indium-tin oxide (ITO) to manufacture flat-panel displays, such as liquid-crystal displays or plasma display panels for televisions, little is known about the potential health hazard induced by occupational exposure to indium compounds. The current study describes a case of fibrotic lung disease that developed after a 4-yr exposure to ITO. The pathology ...
This paper gives an overview of the materials and methods used for fabricating photovoltaic solar cell devices. The technologies discussed include those based on the use of silicon (in the crystalline, multicrystalline, amorphous and micro-crystalline forms), the IIIeV compounds (e.g. gallium arsenide, indium phosphide and gallium antimonide), the polycrystalline compounds (e.g. cadmium telluri...
Indium use has increased greatly in the past decade in parallel with the growth of flat-panel displays, touchscreens, optoelectronic devices, and photovoltaic cells. Much of this growth has been in the use of indium tin oxide (ITO). This increased use has resulted in more frequent and intense exposure of workers to indium. Starting with case reports and followed by epidemiological studies, expo...
Controlling the type of indium salt and hydrosilane enables a highly selective reduction of aromatic nitro compounds into three coupling compounds, azoxybenzenes, azobenzenes and diphenylhydrazines, and one reductive compound, anilines.
