Abstract: The invention relates to a cementitious powder blend comprising, based on total weight—45-90 wt % Portland cement; pref. 50-80 wt %—0-25 wt % siliceous fly ash; pref. 5-20 wt %—0-25 wt % limestone; pref. 5-20 wt %—5-30 wt % polyvinylalcohol, pref. 5-15 wt %. The PVA preferably has—a size distribution with D10=170-270 ?m, D50=370-450 ?m. D90=690-850 ?m and D100=1000-1300 ?m; and—an ester value in the range of 1-250 mg KOH/g, as determinable by EN-ISO 3681:1998 and/or wherein the polyvinyl alcohol has a viscosity of a 4% aqueous solution at 20° C. in the range of 1-40 mPa·s, as determinable by EN-ISO 12058-1:2002. A substantial part of the PVA may be present in the form of hybrid particles composed of Portland cement and the polyvinylalcohol. Further, the invention relates to concrete composed of the cementitious powder blend, water and aggregate as well as flexible concrete products made therefrom.

Abstract: The present invention relates to a device for the removal of toxic substances from dialysate fluid, blood or blood plasma, said device comprising i) a sorption-filter (E) for removing toxins, toxic solutes, toxic small and middle-sized molecules and protein bound toxins from the dialysate fluid, blood or bloodplasma, said sorption filter comprising a nanostructured material, a porous polymer matrix or a combination of the two, ii) an inlet (4) for entry of dialysate fluid, blood or blood plasma into said device, iii) an outlet (5) for the removal of purified dialysate fluid, blood or blood plasma from said device, and iv) a conduit connecting said inlet with said outlet and holding said sorption filter such that said dialysate fluid, blood or blood plasma is forced through said sorption filter.

Abstract: A method for partially metallizing a product comprising a first surface, a first polymer material, and a second surface, a second polymer material, wherein the method comprises the sequential steps of exposing the first and second surfaces to conditions which render the first surface hydrophilic, and the second surface hydrophobic; contacting the first and second surfaces with water or aqueous solution; contacting the first and second surfaces with a solution of a film former in a water-immiscible solvent; evaporating the solvent to allow formation of a film by the film former on the second surface; adherence of a film by the film former on the first surface is prevented by the presence of the water or aqueous solution thereupon; performing a conventional metallization process to deposit a metal layer on the first and second surface; and removing the metallized film from the second surface to render the first surface metallized.

Abstract: Method for metallizing a product (11) comprising a first component (12) and a second component (13). The product is exposed to a first environment (14) causing the surface of the first component to be hydrophilic and the surface of the second component to be hydrophobic. The product is exposed to a watery solution (15a). Next, the product is exposed to a solution (17a) of a film former and subsequently to a second environment (17b), wherein the solvent evaporates and a film (18) is formed covering the whole product, while maintaining the water film under the film. The product then is rinsed out (17c), causing that the film is removed at the locations of the hydrophilic surface of the first component. Next, the product is nucleated, thus forming a nuclei layer (20) and subsequently the film is removed (19b) only leaving the nuclei layer at the hydrophilic surface of the first component.
