Ah&act-By neutron activation analysis the rhodium, silver and indium oontent of five chondritic meteorites has been determined. The average data are 0.186 and 0.094 p.p.m. for rhodium and silver. The upper limit for the indium content is 0.001 p.p.m. The values for rhodium and silver are in fair agreement with the data estimated by SUESS and UREY; the indium values, however, are lower by a fact...

Indium-containing particles (ICPs) are used extensively in the microelectronics industry. Pulmonary toxicity is observed after inhalation exposure to ICPs; however, the mechanism(s) of pathogenesis is unclear. ICPs are insoluble at physiological pH and are initially engulfed by alveolar macrophages (and likely airway epithelial cells). We hypothesized that uptake of ICPs by macrophages followed...

OBJECTIVES To report the occurrence of an advanced case of indium lung disease with severely progressive emphysema in an indium-exposed worker. CASE REPORT A healthy 42-year-old male smoker was employed to primarily grind indium-tin oxide (ITO) target plates, exposing him to indium for 9 years (1998-2008). In 2004, an epidemiological study was conducted on indium-exposed workers at the factor...

Indium doped zinc oxide hierarchical nanostructures have been synthesized using a simple aqueous solution based method. A change in morphology from hierarchical nanostructures in ZnO to nanorods after doping with indium has been observed. The optical properties of nanostructures have been investigated using diffuse reflectance and photoluminescence spectroscopy. The band gap of zinc oxide nanop...

Indium phosphide quantum dots stand out as the most promising candidate to replace the currently commercialized cadmium-containing materials for optoelectronic applications. To produce high-quality materials, significant efforts have been devoted to their synthetic development and growth mechanism studies. This thesis uses experimental and theoretical methods to study the growth of indium phosp...

BACKGROUND During the last decade it has been clarified that the inhalation of indium compounds can evoke alveolar proteinosis, cholesterol granuloma, pulmonary fibrosis and emphysema. In this study, we aimed to elucidate the characteristics and time course of pulmonary disorders among indium workers using comprehensive pulmonary examinations at an indium-processing factory. METHODS Data for ...

the distribution of gallium(b) and indium (b) between hydrochloric or sulphuric acid solution with sec-nonylphenoxy acetic acid(ca-100) in kerosene has been investigated under various conditions. ca-100 is a new organocarboxylic extractant, which has been shown to be efficient for gallium(b) and indium(b) whereas germanium(c), which was not extracted. the extraction system is studied as a funct...

Hybrid infrared focal plane arrays (IRFPAs) are more and more used in both infrared medium and long wavebands for many different applications. In order to offer more spatial resolution, larger format (2048×2048) start to be available, yet its final yield is so low that its cost is very high, and is not affordable. In this paper, basing on viscoplastic Anand’s model, the structural stress of ind...

MicroElectroMechanical System (MEMS) devices often require low-temperature, fluxless soldering techniques due to their high temperature sensitivity and the performance requirements of specific components. While seeking the development of a soldering technology using pure indium, the major focus of this study is to assess the thermodynamics and kinetics of indium oxidation at various solder refl...

In the current work, indium doped zinc oxide thin films were deposited by spray pyrolysis technique on glass substrate at 350 °C. The effect of the preparation conditions on the structural, morphological, optical and electrical properties of the films has been studied. The molar ratio of indium in the spray solution was varied from 0 to 5 at %. All the deposited films are polycrystalline with a...
