Container and preparation method thereof
A container and a preparation method thereof are provided. A material forming the container includes at least two types of oxidized nanocelluloses interlaced with each other, the at least two types of oxidized nanocelluloses being configured to have different degrees of expansion after absorbing moisture in a same environment. In a dry condition, the at least two types of oxidized nanocelluloses do not expand, so the structure of the container is relatively dense and the air permeability is poor, which can sufficiently maintain moisture of an article stored in the container. In case the article itself or other reasons cause high humidity, different oxidized nanocelluloses of the container expand after absorbing moisture, so that gaps between different oxidized nanocelluloses becomes larger, and the air permeability of the container becomes better, which can discharge excessive moisture, enabling the container to self-adjust the air permeability based on humidity.

Aptamer bioconjugate drug delivery device
A delivery device for a active agent comprises nanoparticles based on a biopolymer such as starch. The delivery device may also be in the form of an aptamer-biopolymer-active agent conjugate wherein the aptamer targets the device for the treatment of specific disorders, such as cancer. The delivery device survives for a period of time in the body sufficient to allow for transport and uptake of the delivery device into targeted cells. The degree of crosslinking can provide a desired release profile of the active agent at, near or inside the target cells. The nanoparticles may be made by applying a high shear force in the presence of a cross linker. The particles may be predominantly in the range of 50-150 nm and form a colloidal dispersion of crosslinked hydrogel particles in water.
CEMENTITIOUS COMPOSITIONS COMPRISING OXIDATIVELY DEGRADED POLYSACCHARIDE AS WATER REDUCING AGENTS
Cementitious compositions have an oxidatively degraded polysaccharide as a water reducing agent to provide similar water reducing properties to cementitious composition formulated with lignosulfonates. The oxidatively degraded polysaccharides have the advantage over lignosulfonates of a lower price and a more consistent quality and are expected to be compatible with polycarboxylatether cement additives. Further, methods for the preparation of corresponding cementitious compositions, appropriate oxidatively degraded polysaccharides and methods for producing the same, as well as the use of oxidatively degraded polysaccharides as water reducing agents in cementitious compositions.
Process for the oxidation of starch-based materials
A process for the oxidation of powder materials containing starch, which comprises the steps of mixing a powder material comprising starch with an aqueous solution of hydrogen peroxide (H.sub.2O.sub.2), adding to the mixture thus obtained an aqueous solution of ammonia which reacts with said mixture and drying the mixture to obtain a powder material containing oxidized starch.
