Abstract: The invention provides a hydrogel, having a floating behaviour, wherein 40 to 90% of a solution and/or suspension to be thickened is thickened from the fluid surface and the rest of said solution and/or suspension to be thickened is thickened from the container bottom. Said invention also relates to a method for producing the hydrogel and the use thereof for absorbing blood and/or body fluids, in particular, in hygienic articles, or for thickening aqueous solutions and/or suspensions, in particular, for thickening medical waste.

Abstract: A process for the stabilization of (meth)acrylic acids, (meth)acrylic acid esters and (meth)acrylamide against polymerization comprises use of a stabilizer mixture comprising at least one cerium salt, a further stabilizer compound and an oxygen containing gas. A process for the stabilization of (meth)acrylic acids, (meth)acrylic acid esters and (meth)acrylamide against polymerization comprises use of a stabilizer mixture (I) comprising: (A) at least one cerium salt; (B) a further stabilizer compound; (C) an oxygen containing gas such that cerium acetate and phenothiazine and at least one phenolic compound in the presence of an oxygen containing gas are not simultaneously added to a process for the production of acrylic acid. An Independent claim is included for the stabilizer mixture (I), optionally containing a solvent.

Abstract: Micro-structured, self-cleaning, catalytically-active surface with peaks and hollows contains a catalytically-active material in the hollows. Independent claims are also included forthe following: (a) formed catalyst bodies with an active surface; (b) a method for the production of catalyst surfaces and formed catalysts as above by powder-coating the surface of a support with particles in the size range 0.05-200 microns and then coating with a catalytically-active material; (c) an alternative method comprises: (i) optionally coating the support with a metal primer by layer deposition; (ii) applying a first layer of metal with embedded particles (0.05-200 microns) to the surface of the support or the primer layer by deposition from a solution containing these dispersed particles and (iii) coating with a catalytically-active second layer; and (d) micro-structured, self-cleaning, catalytically-active surfaces and catalysts obtained by these methods.
