Abstract: A process to manufacture nanocrystalline cellulose from cellulose having a low hemicellulose content, said process comprising the steps of:



exposing said cellulose to a microemulsion composition for a first pre-determined period of time, thereby creating a soaked cellulose;
optionally, exposing the soaked cellulose to a sonication step for a second predetermined period of time; and
exposing the resulting mixture to a H2O2 with FeSO4 or CuSO4 under acidic conditions for a third pre-determined period causing hydrolysis of the cellulose;
wherein the nanocrystalline cellulose will have a crystallinity index of more than 50% and an aspect ratio ranging from 10:1 length to width to 50:1 length to width.

Abstract: The present invention relates to a biodegradable polyester resin, in which the first repeat unit comprising a first diol residue and an aromatic dicarboxylic acid residue and the second repeat unit comprising a second diol residue and an aliphatic dicarboxylic acid residue satisfy a ratio of the number of repeat units in a specific range, and the softness index of the resin satisfies a specific range, and to a process for preparing the same. Since the biodegradable polyester resin can provide a biodegradable polyester sheet or film that can be simultaneously enhanced in productivity, processability, and moldability and is excellent in tensile strength, tear strength, and friction coefficient and excellent in biodegradability and water degradability, it can be utilized in more diverse fields.

Abstract: An oxidized β-1,4-oligoglucuronic acid, and a preparation method therefor and uses thereof. By using abundant cellulose in the natural world as the raw material, all 6-site hydroxyl groups of the cellulose β-1,4-polyglucose is oxidized into carboxyl groups to form glucuronic acid under the action of a sodium bromide (NaBr)-2,2,6,6-tetramethyl piperidine oxide (TEMPO)-sodium hypochlorite (NaClO) oxidation system, and the oxidized oligoglucuronic acid having an open ring at an end is prepared by controlling reaction conditions. The compound has obvious anti-cerebral ischemia activity, and can be developed into a potential anti-cerebral ischemia drug.

Abstract: A method for producing a rubber composition include a mixing step, a drying step, and a dispersion step. In the mixing step, an aqueous solution that includes at least one of oxycellulose fibers and cellulose nanofibers is mixed with rubber latex to obtain a first mixture. In the drying step, the first mixture is dried to obtain a second mixture. In the dispersion step, the second mixture is tight-milled using an open roll to obtain a rubber composition. The rubber composition does not include an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.
