Determination of Tellurium in Tellurium-Containing Organic Compounds by Microwave Plasma-Atomic Emission Spectrometry

Tellurium and tellurium compounds

Bacterial recovery and recycling of tellurium from tellurium-containing compounds by Pseudoalteromonas sp. EPR3.

AIMS Tellurium-based devices, such as photovoltaic (PV) modules and thermoelectric generators, are expected to play an increasing role in renewable energy technologies. Tellurium, however, is one of the scarcest elements in the earth's crust, and current production and recycling methods are inefficient and use toxic chemicals. This study demonstrates an alternative, bacterially mediated telluri...

Determination of silicon in diesel and biodiesel by Microwave Plasma-Atomic Emission Spectrometry

The presence of metals and metalloids in petrochemical products can infl uence the performance of engines, and contribute to shortening the lifetime of the machinery. In addition, some elements act as catalyst poison, contributing to increases in the amount of toxic gases and particulate matter emitted by vehicles. Silicon compounds such as siloxanes, for example, are added to diesel as anti-fo...

Purification and in vitro antioxidant activities of tellurium-containing phycobiliproteins from tellurium-enriched Spirulina platensis

Tellurium-containing phycocyanin (Te-PC) and allophycocyanin (Te-APC), two organic tellurium (Te) species, were purified from tellurium-enriched Spirulina platensis by a fast protein liquid chromatographic method. It was found that the incorporation of Te into the peptides enhanced the antioxidant activities of both phycobiliproteins. With fractionation by ammonium sulfate precipitation and hyd...

Ultra-sensitive ROS-responsive tellurium-containing polymers.

A novel tellurium-containing polymer micelle system is reported to be responsive to 100 μM H2O2 and can undergo a series of morphological changes. The polymer micelles also respond to 2 Gy gamma radiation, which is the exact dosage a patient receives per day for clinical radiation therapy.
