Steel converter slag, also called Linz-Donawitz (LD) has been considered as an oxygen carrier for biofuel chemical looping applications due to its high availability. In addition content of iron which contributes oxygen-carrying capacity, LD slag contains a significant amount calcium. Calcium, however, is known interact with sulfur, may affect the usability slag. To get better understanding inte...
The role of riboflavin in the formation and disposal of hydrogen peroxide by streptococcus faecalis.
Certain strains of Streptococcus faecalis when grown under highly aerobic conditions acquire a mechanism that permits them to oxidize a number of substrates without accumulating H202, and in addition enables them to rid the medium of added H202 during the metabolism of these substrates (Seeley and VanDemark, 1951). This mechanism does not involve catalase or the common hematin-containing peroxi...
BACKGROUND Preclinical imaging requires anaesthesia to reduce motion-related artefacts. For direct translational relevance, anaesthesia must not significantly alter experimental outcome. This study reports on the effects of both anaesthetic and carrier gas upon the uptake of [⁶⁴Cu]-CuATSM, [(⁹⁹m)Tc]-HL91 and [¹⁸F]-FMISO in a preclinical model of tumor hypoxia. METHODOLOGY/PRINCIPAL FINDINGS T...
Laser pyrolysis has been used to synthesize WO3 nanostructures. Spherical nano-particles were obtained when acetylene was used to carry the precursor droplet, whereas thin films were obtained at high flow-rates of oxygen carrier gas. In both environments WO3 nanowires appear only after thermal annealing of the as-deposited powders and films. Samples produced under oxygen carrier gas in the lase...
Oxygen is the lifeline of variety of organisms present on the earth. It is one of the basic elements that are involved in the formation of the functional unit of a living being. Various intricacies and mechanisms are there inside the organism that transports the oxygen to each and every cell of the body. Failure of oxygen to reach the brain leads to various kinds of neurodegenerative disease. H...
