Abstract: The invention relates to a method for improving the removal of water in a composition containing microfibrillated cellulose. According to the invention, a cationic polyelectrolyte that has a low molecular weight and a molecular weight of less than 10000 is provided in the composition containing microfibrillated cellulose.

Abstract: The present invention concerns a method of modifying the surface of a cellulosic material, wherein a modifying compound is attached to the cellulosic material through a linker, which linker is a conjugate that has been activated by functionalization prior to adsorption to form an activated conjugate, and wherein the entire method is carried out in aqueous media, as well as an intermediate product suitable for attaching to a modifying compound, the intermediate product comprising said functionalized conjugate linker that has been adsorbed to a cellulosic material.

Abstract: The invention relates to a method for improving strength and retention in the manufacture of paper. According to the invention, a composition containing microfibrillated cellulose is provided in a fiber suspension, and from 0.1 to 10 w-% of microfibrillated cellulose by mass of the fiber suspension is added to improve the strength and retention of the product to be formed. In addition, the invention relates to a corresponding paper product.

Abstract: A method for preparing aqueous furnish to be used in paper or paper board manufacturing. Filler and/or fibers are treated with cationic polyelectrolyte and nanofibrillated cellulose. A furnish and a paper or a paper board.

Abstract: The present invention provides a method for producing modified nanofibrillated cellulose characterized by bringing cellulosic material into a fiber suspension, adsorbing a cellulose derivative or polysaccharide or polysaccharide derivative onto fibers in said fiber suspension under special conditions and subjecting the obtained fiber suspension derivative to mechanical disintegration. A modified nanofibrillated cellulose obtainable by a method of the present invention is provided. Furthermore, the invention relates to the use of said modified nanotibrillated cellulose.

Abstract: The invention relates to a method for coating cellulose particles with a light scattering material, to coated cellulose particles, to the use thereof as a filler and as a coating pigment in paper and board, and further, to methods for producing and for coating paper and board.

Abstract: The invention relates to a method for dissolving cellulose e.g. for the production of regenerated cellulose products such as films, fibres, particles and the like. In said method, the cellulose material is dissolved using an enzymatic treatment, followed by a base treatment. The invention is also directed to a method for producing cellulose particles wherein cellulose dissolved as described above is sprayed or mixed into a regenerating solution for precipitating cellulose particles. Moreover, the invention relates to the use of said cellulose particles produced with this method as a filler and/or coating pigment of paper and board. The invention is also directed to methods for producing and coating paper and board.

Abstract: The present invention is related to a birch BpCol2 nucleic acid sequence and BpCol2-like nucleic acid sequences, which are related to CONSTANS (CO) gene family, and gene products thereof as well as methods and use therein for influencing growth of a plant or roots of a plant. Particularly the invention is related to cloning and expression of BpCol2 gene in plants. The invention is further related to DNA constructs, vectors, transgenic cells, plants and seeds comprising said nucleic acid sequences and gene products.

Abstract: A process for the production of paper from an aqueous suspension containing cellulosic fibers, and optional fillers, which comprises draining the suspension to obtain a paper web and subjecting the obtained paper web to impulse pressing by passage through at least one press nip having at least one heated roll which is in contact with the web and heated to a temperature above 100° C., wherein a chemical system comprising a polymer component and micro- or nanoparticles are added to the suspension or the paper web before the paper web passes the press nip of the impulse unit.
