A well treatment composition for use in a hydrocarbon-bearing reservoir comprising a reversible aminal gel composition. The reversible aminal gel composition includes a liquid precursor composition. The liquid precursor composition is operable to remain in a liquid state at about room temperature. The liquid precursor composition comprises an organic amine composition; an aldehyde composition; a polar aprotic organic solvent; and a metal salt composition with valence 3, 4, or 5. The liquid precursor composition transitions from the liquid state to a gel state responsive to an increase in temperature in the hydrocarbon-bearing reservoir. The gel state is stable in the hydrocarbon-bearing reservoir at a temperature similar to a temperature of the hydrocarbon-bearing reservoir, and the gel state is operable to return to the liquid state responsive to a change in the hydrocarbon-bearing reservoir selected from the group consisting of: a decrease in pH in the hydrocarbon-bearing reservoir and an addition of excess metal salt composition in the hydrocarbon-bearing reservoir.

The present invention pertains to a resin composition which includes component: a membrane-forming polymer, component: a polymer obtained by polymerizing a monomer composition which includes a (meth)acrylic ester macromonomer represented by general formula and another monomer, and component: a polymer including a vinylpyrrolidone unit, a membrane-forming stock solution which includes the resin composition, a porous membrane obtained by forming with the membrane-forming stock solution, and a hollow fiber membrane, a water treatment device, an electrolyte support, and a separator which use the porous membrane.

An object of the present invention is to provide a flux in which the occurrence of a bridge and a ball is suppressed at the time of soldering, and a resin composition for the flux. The flux comprising: at least one selected from 0.3 to 2.0 mass % of an organochlorine compound, and more than 0.04 mass % and 1.00 mass % or less of an amine hydrochloride; and 0.2 to 1.5 mass % of an organophosphorus compound that is at least one selected from a phosphonic acid ester and a phenyl-substituted phosphinic acid, each based on the whole flux.

A heat energy storage system may have a shape-stabilized composite prepared using an easy impregnation method involving a porous Ca.sup.2+-doped MgCO.sub.3 matrix and PEG as the functional phase. The heat storage capability, microstructures, and interactions with the PEG/CaMgCO.sub.3 composite can be characterized by DSC, SEM imaging, FT-IR spectroscopy, and TGA. Likely because of the synergistic phase change effect of CaMgCO.sub.3 and PEG, the PEG/CaMgCO.sub.3 composites can have high thermal enthalpies, and their enthalpy efficiencies are substantially higher than those of traditional shape stabilized PCMs. The functional material PEG can permeate porous CaMgCO.sub.3 matrices under capillary action. Liquid PEG can be stabilized within the porous matrix, and/or the CaMgCO.sub.3 matrix can improve the thermal stability of the PEG. The high heat energy storage properties and good thermal stability of such organic-inorganic composites offers utility in a range of applications, including thermal energy storage.
