A moulding process, in particular a bladder inflation moulding process for the production of a composite material based part, said composite material comprising a polymer matrix and reinforcing fibres, wherein at least a portion of external surface of said ...
A high mol. wt. water sol. acrylamide based polymer having improved flocculating properties is provided. The polymer is prepd. by a process, in which a small quantity of a chain branching agent such as methylenebisacrylamide is added to the polymn. reactio ...
Microstereolithography is a technique that allows the manufacture of small and complex three-dimensional (3D) components in plastic material. Many of the components produced by this technique are too small and too complex to be replicated by molding and, c ...
High precision positionning and assembly as well as micro-machining require dedicated devices. These devices have to provide high repeatability and precision on several degrees of freedom (dof). High dynamic characteristics are also sought to reach short t ...
The microstructure of an AlCu4Mg1Ag alloy reinforced with 15 vol% Al2O3-Saffil fibers was investigated by analytical transmission electron microscopy and compared to the microstructure of the unreinforced alloy. The investigation results show that the comp ...
A high molecular weight water soluble graft copolymer having improved flocculating properties is provided. The backbone chain is a heteropolysaccharide comprising amino groups, in particular chitosan, grafted with one or more monoethylenically unsaturated ...
A high mol. wt. water sol. acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepd. by a process in which a small quantity of a chain branching agent is added to the polymn. reaction mixt. continuou ...
(Ecole Polytechnique Federale De Lausanne (Epfl), Switz.).2002
A copolymer containing 88% 2-hydroxyethyl methacrylate (HEMA), 9% poly(ethylene glycol) (MW 18.5 kDa) tetra-acrylate and 3% ethylene dimethacrylate was prepared and evaluated for use as a biocompatible interface between glucose biosensors and tissue in the ...
NOVELTY - A hydraulic binder comprises a source of calcium aluminate, calcium silicate, sulfate, and a source of reactive silica. The ingredients are present in such relative proportions that, upon hydration, both monosulfate and hydrated alumina are forme ...
