摘要:
Described herein is an improved conversion of nitrous oxide (N2O) present as a by-product in a chemical process to NOx which can be further converted to a useful compound or material, such as nitric acid.
摘要:
A nitric oxide delivery device includes a housing that is permeable to nitric oxide. A working electrode (which is a copper-containing conductive material or a base material coated with a copper-containing conductive material) is positioned inside of the housing. A conductive lead is electrically connected to the working electrode and extends outside of the housing. A reference electrode and/or a counter electrode is electrically isolated from the working electrode. The reference electrode and/or the counter electrode has a first portion that is inside of the housing and a second conductive portion that is outside of the housing. A source of nitrite ions is to be contained within the housing such that it is in contact with the working electrode.
摘要:
An apparatus to generate nitric oxide is disclosed in one embodiment in accordance with the invention as including a heat source and a vessel containing the heat source. A tablet may be placed within the vessel such that it is in thermal communication with the heat source to receive heat therefrom. The tablet may contain reactants that are substantially non-deliquescent and form nitric oxide in response to heat from the heat source.
摘要:
A nitric oxide delivery system, which includes a gas bottle having nitrogen dioxide in air, converts nitrogen dioxide to nitric oxide and employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid. A nitric oxide delivery system may be used to generate therapeutic gas including nitric oxide for use in delivering the therapeutic gas to a mammal.
摘要:
Fe2(dobdc) has a metal-organic framework with a high density of coordinatively-unsaturated FeII centers lining the pore surface. It can be effectively used to separate O2 from N2 and in a number of additional separation applications based on selective, reversible electron transfer reactions. In addition to being an effective O2 separation material, it can be used for many other processes, including paraffin/olefin separation, nitric oxide/nitrous oxide separation, acetylene storage, and as an oxidation catalyst.
摘要:
The electronic structure of nanowires, nanotubes and thin films deposited on a substrate is varied by doping with electrons or holes. The electronic structure can then be tuned by varying the support material or by applying a gate voltage. The electronic structure can be controlled to absorb a gas, store a gas, or release a gas, such as hydrogen, oxygen, ammonia, carbon dioxide, and the like.
摘要:
Methods and compositions are provided for generating and applying long-lasting therapeutic nitric oxide (NO) gas from the reaction of a least one microencapsulated nitrite salt and an activating volume of an aqueous acidified gel that has sufficient acidity to convert the nitrite salt to a nitric oxide (NO) and further provides a reducing property that retains the NO in bioactive form
摘要:
The invention relates to a method for producing an NO/N2 gaseous mixture, comprising the steps of effecting a purification of impure gaseous nitrogen containing impurities at least of the O2 type by putting the impure nitrogen in contact with a catalyst and then with a molecular sieve; mixing the pure nitrogen obtained with nitric oxide (NO), and obtaining a mixture formed from NO and pure nitrogen containing an NO content of less than 20% by volume and a proportion of impurities of the O2 type of less than 5 ppmv and of the H2O type of less than 40 ppmv. The NO/nitrogen mixture may undergo supplementary dilutions with pure nitrogen. Such NO/nitrogen mixtures can be used for treating, by inhalation, pulmonary vasoconstrictions in adults or children, in particular in new-born babies suffering from primitive pulmonary hypertension or in patients undergoing heart surgery.
