摘要: A method for producing a chemical reactor device based on a fluid flow comprises obtaining a substrate with a fluid channel defined by a channel wall, in which an ordered set of silicon pillar structures is positioned in the fluid channel and electrochemically anodising at least the silicon pillar structures to make the silicon pillar structures porous at least to a certain depth. After the anodising, the substrate and pillar structures are thermally treated, the treatment being carried out at a temperature, with a duration and in an atmosphere such that any silicon oxide layer formed has a thickness of less than 20 nm. The substrate and the pillar structures are further functionalized.

摘要: Methods and for treatment of cancer and other diseases including complications from late stage viral infections by inducing hyperthermia in a patient relying on withdrawing blood from the patient and returning the withdrawn blood to the patient to establish an extracorporeal flow circuit. Blood is heated by passing through the extracorporeal circuit at a controlled rate until a target body core temperature in is achieved. Usually, the blood will be subjected to a continuously re-circulating dialysis to balance electrolytes. Additionally, the blood will be subjected to a continuously recirculating regeneration through a carbon sorbent column where toxins and contaminants are removed. The blood temperature is maintained at the target blood temperature for a treatment period, and the blood is cooled after the treatment period has been completed. The method can also be effective in treating rheumatoid arthritis, scleroderma, hepatitis, sepsis, the Epstein-Barr virus, and patients with life threatening complications from other viruses, including the COVID-19 virus. A method for removing viruses from the blood supply in an external circuit is also presented.

摘要: The present disclosure relates to systems and methods of making ammonia using stable ammonia absorbents. The system and method for producing ammonia, comprises a reactor comprising a catalyst that converts at least a portion of nitrogen feed gas and at least a portion of hydrogen feed gas to ammonia (NH3) forming a reaction mixture comprising the ammonia, unreacted nitrogen, and unreacted hydrogen. An absorber configured to selectively absorb ammonia from the reaction mixture at a temperature of about 180 deg. C. to 330 deg. C. and a pressure of about 1-20 bar, the absorber comprising a solid absorbent. Preferably the solid absorbent is at least one metal halide and a solid support. The unabsorbed ammonium, the unreacted nitrogen, and unreacted hydrogen gas are recycled to the reactor.

摘要: A superabsorbent polymer composition includes superabsorbent polymer particles, having a crosslinked polymer of water-soluble ethylenically unsaturated monomers including acid groups, of which at least a part are neutralized; and a particulate antimicrobial agent having a quaternary ammonium salt of a silane-based compound. The superabsorbent polymer composition exhibits improved antimicrobial and deodorizing properties without deterioration of the superabsorbent polymer properties such as centrifugal retention capacity.

摘要: A method of water treatment includes flowing water that includes nitrogen and phosphorus compounds through a sorption media composition within at least one chamber of a water treatment system. The composition comprises iron filings comprising at most 5 volume (vol) % of the composition, sand particles comprising at least 80 vol % of the composition, and clay particles comprising at most 5 vol % of the composition. The iron filings, sand particles, and clay particles are mixed together. During the flowing, the clay particles attract the nitrogen and phosphorus compounds, which become absorbed onto a surface of the iron filings and the clay, resulting in a removal of the nitrogen and phosphorus compounds and the generation of reaction products. Nitrogen and phosphorus are then recovered from the reaction products.
