Abstract: The present invention refers to a method for the separation of a liquid mixture comprising water and a hydrophobic liquid, especially for oil-water separation, comprising the step of contacting the liquid mixture comprising the hydrophobic liquid and water with a hydrophilically coated mesh allowing water to pass through the mesh while at least part of the hydrophobic liquid remains on the mesh, wherein the mesh is a weave with a geometric pore size of less than 100 μηη having warp threads, the warp threads having a diameter dw, and shute threads, the shute threads having a diameter ds, wherein ds and dw differ by at least a factor of 1.1 and wherein the surface of the mesh is at least partly covered by a hydrophilic coating, the hydrophilic coating having a contact angle for water of less than 10°. The invention further relates to the hydrophilically coated mesh and its use.

Abstract: Un proceso para preparar partículas recubiertas con sílice de un agente expansor inorgánico, las partículas recubiertas con sílice y su uso. Las partículas recubiertas con sílice muestran una liberación demorada del agente expansor, en particular en medio alcalino y a temperaturas elevadas. Por lo tanto, son útiles en la industria del petróleo y de la construcción.

Abstract: Coated inorganic expanding agent particles comprise a core of an inorganic expanding agent and a sol/gel-formed coating comprising a mixed oxide of two or more metals and/or metalloids, in particular a mixed oxide of silicon and at least one metal and/or metalloid selected from aluminum, boron, titanium, zirconium and zinc. The coated inorganic expanding agent particles are added to cementitious systems to avoid shrinkage during hardening. The coating is effective to delay the expanding effect.

Abstract: The invention relates to a process for preparing silica-coated particles of an inorganic expanding agent, the silica-coated particles and their use. The silica-coated particles show a delayed release of the expanding agent particularly in alkaline medium and at elevated temperatures. They are therefore useful in the oil and construction industry.
