An overview highlighting the anti-cancer potential of (bio-essential) seleniumand tellurium-containing species, with an emphasis on biological targets and mechanisms of action, is presented. Studies thus far have focused on selenium(II) compounds (along with – to a lesser extent – inorganic selenium and selenium nanoparticles) which often successfully exploit the inherent anti-oxidizing ability...

Tellurium thin films were studied for use as ammonia gas sensors operable at room temperature. The films showed a reversible increase in resistance when exposed to ammonia and the response was found to be linear in the range of 0-100 ppm. The interaction of ammonia with tellurium film was investigated using Raman, X-ray photoelectron and impedance spectroscopy techniques. The results of Raman a...

Thallium is commonly found with lead, zinc, iron, tellurium and the alkalis . It is normally present only at trace level (¡10 μg L−1) in natural waters. It is toxic and is on several regulatory lists . Determination of trace amounts of thallium is of great importance because of its toxic nature and also because of its increasing industrial applications . The main sources of thallium pollution a...

Since several days, radioactive pollution was observed in the marine environment, at varying distances from the Fukushima-Daiichi power station. The main radionuclides regularly found in the sea water are (T = radioactive half-life): iodine 131 (T = 8 days), caesium 137 (T = 30 years), caesium 134 (T = 2.1 years), caesium 136 (T = 13.1 days), tellurium 132 / iodine 132 (T = 78 hours). Others ha...

In this article, we present Tellurium, a powerful Python-based integrated environment designed for model building, analysis, simulation and reproducibility in systems and synthetic biology. Tellurium is a modular, cross-platform, and open-source integrated development environment (IDE) composed of multiple libraries, plugins, and specialized modules and methods. Tellurium ensures exchangeabilit...

Formation of the hydrides of antimony arsenic, bismuth, germanium, lead, selenium, tellurium and tin by reaction with sodium tetrahydroborate0 affords an excellent method for the separation of these elements as gases from a wide range of matrices. Excellent low limits of detection are attained when this separation method is combined with atomisation of the hydride in a heated quartz tube in the...
