Abstract: Particles of a polysaccharide derivative, having at least one substituent with conjugated unsaturated bonds and exhibiting an index of refraction in excess of 1.50 and a method for the production thereof. In the method, the raw-material is suspended in an organic solvent to form a suspension, which is contacted with an organic reactant comprising a residue with conjugated unsaturated bonds; the raw-material and the organic reactant are reacted to form a derivative exhibiting ester or ether bond between the raw-material and the residue with conjugated unsaturated bonds; the polysaccharide derivative is dissolved in a solvent to form a solution; and the solution is contacted with a non-solvent to precipitate particles of the polysaccharide derivative. The invention provides lightweight, optically improved organic pigments and fillers based on renewable resources and which are recyclable by combustion or composting.

Abstract: A process for the production of a lignocellulose-containing material, in which, based in each case on the lignocellulose-containing material: A) from 30 to 95% by weight of lignocellulose particles; B) from 1 to 25% by weight of expanded plastic particles having a bulk density in the range from 10 to 150 kg/m3; C) from 1 to 50% by weight of a binder selected from the group consisting of aminoplast resin, phenol-formaldehyde resin and organic isocyanate having at least two isocyanate groups, and optionally D) additives are mixed and are then pressed at elevated temperature and under elevated pressure, wherein the component B) comprises a formaldehyde scavenger.

Abstract: A method for the preparation of a composite product, as well as the composite product. The composite product comprises at least two layers. At least one of the layers is of wood or another cellulose-containing material. The process comprises differentially treating the layers prior to, during, or after the lamination of the layers into a composite product.

Abstract: A material suitable for the reconstruction of an individual's tissue, particularly supportive tissue such as bone tissue, insertable into the tissue. The material is characterized by being composed of wood heat-treated within the temperature range of 100-220° C. in the presence of water vapor. The invention also relates the use of the wood.

Abstract: A method for the production of a robust, chemically stable, crystalline, passivated nanoparticle and composition containing the same, that emit light with high efficiencies and size-tunable and excitation energy tunable color. The methods include the thermal degradation of a precursor molecule in the presence of a capping agent at high temperature and elevated pressure. A particular composition prepared by the methods is a passivated silicon nanoparticle composition displaying discrete optical transitions.

Abstract: A nanoparticle comprising an inorganic core and a polymerizable outer coating. The inorganic core comprises a substantially crystalline inorganic material such as a superparamagnetic material. In one embodiment, the inorganic core comprises a single crystal mixed spinel ferrite comprising iron in a first oxidation state and at least one metal in a second oxidation state, wherein the second oxidation state is different from the first oxidation state.

Abstract: The present invention relates to use of an alkylhydroxyalkyl cellulose, which has alkyl groups having 1-3 carbon atoms and hydroxyalkyl groups having 2-3 carbon atoms, is free from hydrophobically modifying alkyl groups having at least 4 carbon atoms and has a turbidity point of 50-95° C. The amount of carboxymethyl cellulose constitutes up to 1200 percent by weight of the amount of alkylhydroxyalkyl cellulose. An aqueous coating composition containing a combination of alkylhydroxyethyl cellulose and carboxymethyl cellulose is also described.
