  • Patent number: 10017648
    Abstract: The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

  • Patent number: 9969617
    Abstract: This disclosure relates to the release of singlet oxygen by thermally activated decomposition of aromatic endoperoxide molecules in material systems [e.g. polymer (nano)particles or polymer films]. Due to the short lifespan and diffusion length of singlet oxygen, the technical problem is that the majority of the decomposition may only take place if the singlet oxygen molecules can reach the target region. For example, either the penetration of the polymer particles into the cancer cells to be killed, or the settlement of bacteria on an implant coated with the polymer film, must be accomplished. It is necessary to allow adaptation of the time progression of the decomposition for the application. The adaptation is performed by chemically and/or physically modifying the functional structures present in the material system, each made of the molecule forming the endoperoxide and at least one adjacent molecule or the cage formed by all adjacent molecules.

  • Patent number: 9079772
    Abstract: Water molecules, preferably in the form of steam or water vapor, are introduced into a radiant energy transfer reactor. The radiant energy is absorbed by the molecules which dissociate into their constituent molecular elements of hydrogen and oxygen. To prevent recombining of the constituent molecular elements, the hydrogen and oxygen are separated from each other. Various devices may be employed to effect this separation. Once separated, the molecular components are prevented from recombining with each other or with other elements by using standard separation techniques normally employed for separating dissimilar gaseous species.

The catalysts described herein are stable and active at neutral pH and in a wide range of buffers that are both weak and strong proton acceptors. While its activity is slightly lower than state of the art cobalt-based water oxidation catalysts under some conditions, it is capable of sustaining electrolysis at high applied potentials without a significant degradation in catalytic current. This enhanced robustness gives it an advantage in industrial and large-scale water electrolysis schemes.

  • Patent number: 8604263
    Abstract: The disclosure relates to energy and the production of cost-effective power sources as hydrocarbons and hydrogen, as well as an oxidizer, such as oxygen. In an embodiment, the method of hydrocarbons, hydrogen and oxygen production includes a number of stages, including water saturation with carbon dioxide to form a saturated carbonated water; passing of the carbonated water through the reactor, which contains a catalyst, with the formation of hydrocarbons, hydrogen and oxygen, that subsequently flow into a separator; separation of reaction products from the initial carbonated water in the separator by liquid and gaseous phase separation, while hydrocarbons are separated from the liquid and gaseous phases, and hydrogen and oxygen are additionally separated from the gaseous phase.

  • Publication number: 20130295002
    Abstract: A self-regulating gas generator that, in response to gas demand, supplies and automatically adjusts the amount of gas (e.g., hydrogen or oxygen) catalytically generated in a chemical supply chamber from an appropriate chemical supply, such as a chemical solution, gas dissolved in liquid, or mixture. In some embodiments, the gas generator may employ a piston, rotating rod, or other element(s) to expose the chemical supply to the catalyst in controlled amounts. In another embodiment, the self-regulating gas generator uses bang-bang control, with the element(s) exposing a catalyst, contained within the chemical supply chamber, to the chemical supply in ON and OFF states according to a self-adjusting duty cycle, thereby generating and outputting the gas in an orientation-independent manner. The gas generator may be used to provide gas for various gas consuming devices, such as a fuel cell, torch, or oxygen respiratory devices.

  • Patent number: 8568510
    Abstract: A gas separation process for treating off-gas streams from reaction processes, and reaction processes including such gas separation. The invention involves flowing the off-gas across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, and passing the permeate/sweep gas mixture to the reaction. The process recovers unreacted feedstock that would otherwise be lost in the waste gases in an energy-efficient manner.

  • Publication number: 20130251622
    Abstract: Methods and systems are provided for producing oxygen through pressure and temperature swing absorption using molten salt under non-corrosive process conditions. The process relies on the ability of the molten salt mixture to selectively absorb oxygen from a gas mixture (e.g. from air) by means of an oxidation reaction under certain process conditions, and subsequently desorb the oxygen from the molten salt mixture by means of the reverse decomposition reaction to produce oxygen under other conditions. Unlike conventional methods, the process parameters may be optimized to obtain operating conditions substantially noncorrosive to conventional high-temperature alloys. Advantages of certain embodiments include reduced process corrosivity, lower cost, and lower energy demands. Optional features include energy economization with external processes and reduction of carbon dioxide footprint compared to currently available processes.
