    Abstract: The invention discloses a method for manufacturing alveolate cellulose products (sponges, sponge-cloths...), from a cellulose raw material, which comprises: dissolving at least partially the said cellulose raw material in an intrinsic solvent; incorporating, under agitation, into the resulting mixture an effective amount of at least one pore forming agent; the said pore forming agent(s), compatible with the cellulose mixture, being suitable for generating, when their action develops, a macro- and a microporosity; gelling the consistent homogeneous mass thus obtained; treating the said gelled mass under conditions where the dissolved cellulose precipitates and the action of the pore forming agent(s) present develops. The said method is an advantageous alternative to the polluting viscose method. The products obtained have properties quite similar to those of the products obtained by the said viscose method. The said new products are part of the invention.

    Abstract: The objective of the present invention is to provide a method for easily and efficiently producing cellulose beads which have pore shape suitable for an adsorbent and of which adsorption performance is excellent without using highly toxic and highly corrosive auxiliary raw material and without industrially disadvantageous cumbersome step. The method for producing porous cellulose beads according to the present invention is characterized in comprising (a) the step of preparing a fine cellulose dispersion by mixing a low temperature alkaline aqueous solution and cellulose, (b) the step of preparing a mixed liquid by adding a crosslinking agent to the fine cellulose dispersion, (c) the step of preparing an emulsion by dispersing the mixed liquid in a dispersion medium, (d) the step of contacting the emulsion with a coagulating solvent.

    Abstract: The present invention aims to provide a method for preparing a bio-based material which includes the steps of extracting celluloses from lignocellulosic biomass and regenerating a cellulose film. After that, preparing a metal-graphene oxide nano-composite and subsequently mixing the metal-graphene oxide nano-composite into the cellulose film solution to form an interaction mixture. Subsequently, the interaction mixture is coagulated in a non-solvent coagulant, and a highly porous structure of a cellulose membrane is regenerated. Particularly, the regenerated cellulose membrane has anti-bacterial properties and is tested against Gram-positive and Gram-negative bacteria.

    Abstract: A multi-cellular cellulose particle having a multiplicity of cells spaced from one another by cell membranes is described, which cells have a maximum inscribed sphere diameter of larger than 2 µm. The cells have a continuous hole structure in which cells the cells communicate with one another through openings in the membranes separating two adjacent cells. The multi-cellular cellulose particle is prepared by forming drops of a solution of cellulose or a cellulose derivative, cooling the drops at a temperature lower than the solidification temperature of the solution to freeze the drops, and removing the solvent by extraction or nullifying the dissolving power of the solvent.
