Abstract (sommario):

A continuing demand exists to develop the capabilities of nanosatellites. A key element limiting the range of nanosatellite applications is the accommodation of a propulsion system. This research investigated this need and considered the miniaturisation of a monopropellant thruster. A literature review considered all aspects of micropropulsion together with enabling technologies. Assessment of present micropropulsion developments revealed that few would conform to the nanosatellite constraints. In addition the complexities associated with the miniaturisation of a propulsion system such as the

Abstract (sommario):

In airway epithelia, lactoperoxidase (LPO) constitutes an important anti-microbial system to protect the host against infection and inflammation. LPO uses hydrogen peroxide and thiocyanate anion to form the biocidal compound, hypothiocyanite. The rate-limiting factor is hydrogen peroxide substrate availability. This study was conducted to identify the major source of hydrogen peroxide and to characterize its regulation in the human airway. Two homologues of the phagocytic NADPH oxidase, Duox1 and Duox2, were shown to be highly expressed and functional in human airway epithelial cells re-differ

Abstract (sommario):

Hydrogen peroxide (H2O2) is a valuable chemical with rapidly growing demand in a variety of applications. At present, industrial production of H2O2 is through an energy-intensive anthraquinone process with high production costs and environmental hazards. Recently, the reported noble-metal based catalysts such as Pd-Au alloy, using renewable electricity to generate H2O2 via two-electron transferred oxygen reduction reaction (2e–-ORR), has received much attention. However, the cost and abundance of noble metals limit such catalysts for large-scale applications. To reduce the high overpotential r

Abstract (sommario):

Hydrogen peroxide (H2O2) is a versatile environmentally friendly oxidizing agent that has many practical applications. H2O2 has countless qualities and it is one of the world’s most important bulk inorganic chemicals. Most of the world’s H2O2 is produced by auto-oxidation process (AO). The AO process involves indirect oxidation of H2 to yield H2O2. The first commercial anthraquinone (AQ) process was operated by I.G. Farbeinindustrie in Germany during the second world war. The AO process is successfully used to produce most of the world’s H2O2 because it avoids explosive H2/O2 gas mixture. Ho

Abstract (sommario):

The direct synthesis of hydrogen peroxide from hydrogen and oxygen over supported gold, palladium and gold palladium catalysts was studied in a high-pressure stirred autoclave containing a stabiliser-free solvent system. The rate of H2O2 synthesis for supported Au catalysts was found to be lower than that of the Pd only catalysts. However, carbon, titania, iron oxide and alumina supported Au-Pd catalysts are significantly more active and selective for H2O2 synthesis than the monometallic catalysts. For silica supported gold-palladium catalysts, the activity was found to scale directly with pal

Simultaneous electrosynthesis of alkaline hydrogen peroxide and sodium chlorate in the same cell was investigated. The alkaline hydrogen peroxide was obtained by the electroreduction of oxygen in NaOH on a fixed carbon bed while the chlorate was obtained by the reaction of anodic electrogenerated hypochlorite and hypochlorous acid in an external reactor. An anion membrane, protected on the anode side with an asbestos diaphragm was used as the separator between the two chambers of the cell.

Abstract (sommario):

PFAS are a group of relatively newly discovered man-made pollutants. PFAS contains a C-F bond which is one of the strongest bonds in organic chemistry. Therefore, PFAS are not easily degradable and, once release into nature, are very persistent. PFAS are also labile in natural environments and therefore, they can sometimes be found far from the source of pollution. Their persistent and labile nature, in combination with their bioaccumulation ability and human health effects make of this compounds an important contaminant to take care of.

Transmembrane water channel proteins, known as aquaporins (AQPs), play a pivotal role in many biological processes including volume regulation, cell migration and proliferation, and adipocyte metabolism. Recently, it has been demonstrated the involvement of some AQPs, known as “peroxiporins”, in the transport of hydrogen peroxide (H2O2). H2O2 is the most abundant and stable reactive oxygen species (ROS) in living cells and H2O2 can have different effects depending on its concentration. Physiological levels of H2O2 induce positive adaptive responses acting as second messenger, while excessive l
