A method of extracting hydrocarbons from a subterranean formation includes injecting a surfactant composition into the subterranean formation and collecting hydrocarbons displaced by the injected surfactant composition. The surfactant composition can have at least one polyamine surfactant compound of formula R1R2NA(RNA)NR3R4, where x is an integer from 0 to 3, R1, R2, R3, R4 and each R are independently a hydrogen atom or an alkyl group, each A is an alkylene group, and the total number of carbon atoms in the surfactant compound is from 10 to 21. The surfactant composition can include liquid or supercritical carbon dioxide.

A method for determining the amount of hydrocarbons in a composition including hydrocarbons and water is provided. The method includes adding a chemical agent to the composition in order to form an emulsion of water and hydrocarbons, taking a sample of the emulsion and dissolving this sample in a common solvent for water and hydrocarbons in order to form a solution, and measuring the amount of hydrocarbons in the solution. An installation suitable for implementing this method is also provided.

The present invention relates to bitumen emulsions that can be used in roadmaking applications for the production of cold mixes, emulsion-stabilized gravel and road pavements obtained at ambient temperature, the cohesion of which at young age is substantially improved over the cold mixes, emulsion-stabilized gravel and road pavements of the prior art. These bituminous emulsions are characterized by a median diameter of 0.6 &#x3bc;m or less, and preferably 0.5 &#x3bc;m or less.

A glass article, especially of hollow glass, carries a coating resulting from the deposition, in one or two stages, onto the surface of the glass, of at least one monoaminosilane and of at least one lubricating substance such as an optionally oxidized or partially oxidized polyolefin. The coating provides desirable properties of wet and dry abrasion resistance (scratch resistance), substantial invisibility, and adhesiveness for labels. Articles having labels directly attached to said coating are also provided as well as the process for obtaining the desired properties.

A target element is formed by creating a precursor system which may yield an inorganic material at a temperature of 300-1600 C. which is lower than the melting point of said material. The precursor system contains an inorganic additive having a melting point no higher than. The precursor system is applied to a support other than a foam or metal felt, the resulting assembly is heated to said temperature and this temperature is maintained for a sufficient time to produce said inorganic material, whereafter the assembly formed by the inorganic material and the support is gradually cooled to room temperature. To produce the target, the target element (2) is bonded to a metal substrate (4) by means of a layer (3) of conductive adhesive.

An electrochromic element useful in an electrochromic glass or mirror device and a process for making such element. The element is a five-layered structure including an electrolyte ion conducting layer interposed between first and second inorganic electrochromic layers which are interposed between a pair of conductive electrodes. The first and second inorganic electrochromic layers are different and are capable of exhibiting color-forming properties complementary to one another upon the incorporation of an alkali metal or Ag ion, a mixture of alkali metal or Ag ions or a mixture of alkali metal or Ag and hydrogen ions. The electrolyte ion conducting layer may be a copolymer of ethylene oxide, butylene oxide or methyl glycidyl ether, and optionally a small amount of allyl glycidyl ether, along with an ionizable salt, or may be a polyurethane gel formed by reacting the copolymer with triisocyanate, along with an ionizable salt. The second inorganic electrochromic layer comprises a transition metal oxide which exhibits a color change when shifting between the +2 and +3 valence states. The second inorganic electrochromic layer may be produced by an electrochemical process, a chemical process, or by a physical process. The electrochromic element may also comprise a plurality of five-layer structures in tandem, each pair separated by a substrate.

A composition and process for modifying the surface region of a polymer article. The composition is a mixture of a resin surface modifier ingredient, a resin-swellable organic solvent and a surfactant additive. The composition is contacted with the surface of a resin article, while the article is immersed in a liquid which may also contain a surfactant which is non-aggressive toward the article and immiscible with the solvent. The surfactant alters the wetting characteristics of the air-liquid, or liquid-surface modifier interfaces, or both interfaces, so that a film of the modifier ingredient does not form on the surface of the liquid layer.

The present invention relates to a process for the preparation of a microemulsion of water or water and another additive, especially alcohol or amine, in a liquid fuel, in the presence of a surface active agent. Such microemulsions are intended to be used as fuel in an engine or a burner.
