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

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...

RECYCLING OF CdTe PHOTOVOLTAIC MODULES: RECOVERY OF CADMIUM AND TELLURIUM

Research on recycling of CdTe PV modules and manufacturing waste aims in optimizing the separations and recovery of glass, cadmium and tellurium while minimizing life-cycle emissions and energy use, under the constraint of low cost (e.g. a few cents per watt). The major tasks of our research are: a) Cleaning of glass from the metals and recycling of glass; b) separation of Te from Cd and other ...

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.
