Abstract: The present invention is related to the field of liquid disinfectant formulas, specifically with obtaining disinfectant compositions applicable to hard and smooth surfaces, porous surfaces and for human use; particularly with disinfectant compositions that allow the surface or surfaces where it is applied, a disinfection with a prolonged effect, for periods greater than 24 hours. More particularly with the use of long-lasting disinfectant compounds, some of them approved by international agencies such as the EPA, and which are also approved by the FDA for cosmetic use due to their low or null toxicity. More particularly, the present invention relates to the formulation of said compositions.

Abstract: The object of this invention is a process for manufacturing, conditioning and stabilization of a family of base additives sodium, potassium, boron, silicon, zinc, calcium oxides, among others, prepared by physicochemical and chemical synthesis methods that form nanometric structures, reformulated with deflocculant, sequestrants and dispersants additives that allow to obtain a dispersion or powder capable to decrease the sintering temperature of a ceramic body due to the high fluxing power, which is maximized by the use of nanotechnology in the structures obtained. The process consists in the preparation of nucleation seeds of metal, silicates and carbonates oxides by means of a physicochemical process, and which allow nanometric structures to grow by means of a chemical process in a chemical synthesis process wet basis of sodium, boron, silicon, zinc, potassium and calcium oxides.

Abstract: A method and an apparatus for systematic suppression and separation of interactive acoustic modes within a liquid-filled spherical resonator are described. The method and apparatus allow for augmenting the response and acoustic energy of liquid-filled spherical shell resonators. In some aspects, manipulation of acoustic resonant modes is used to achieve desirable conditions. The response of a system can be influenced by one or more of the interactive modes, which are more sensitive to a change in the speed of sound. This is attained in some cases by changing parameters, which are a function of the speed of sound in a liquid medium, such as, temperature and pressure.

Abstract: Acoustic resonators and systems for controlling the same to cause desired reactions and physical effects therein are described. Some aspects are directed to an acoustic cavitation resonator that can be placed under high static pressure and to which a set of ultrasonic drivers are coupled so as to cause cavitation in the resonator during operation. Inlet and outlet ports allow introduction of one or more fluid species into the resonator so that the desired processing of the fluids can be accomplished under pressure and in the presence of cavitation.

Abstract: This invention provides a novel method for separating alkaline salts from industrial byproduct mixtures of solid containing a source of the alkaline salt and a free carbonaceous material. In one embodiment, the industrial byproduct may be a mixture of solid materials that comprises: sodium carbonate, hydrate phases of sodium carbonates, free carbon particulates, water and minor amounts of insoluble materials as impurities. An external source of heat is initially applied to the byproduct mixture to raise the temperature of the free carbon particulates to the ignition point at which time a source of oxygen, introduced into the byproduct mixture, reacts with the heated carbon particulates and combine exothermally to form carbon dioxide gas and autogenously release thermal energy.
