  • Patent number: 10272364
    Abstract: The present invention relates to a novel stationary phase support for liquid chromatographic chiral separations. The specific combination of the special underlying support material and certain classes of known chiral selectors according to the invention produces far superior chiral (enantiomeric) separations than those obtained on any conventionally known supports. These chiral (enantiomeric) separations are enhanced in terms of significantly higher efficiencies (theoretical plate numbers), higher resolutions (Rs), shorter retention times and either equivalent or slightly higher selectivities than those obtained on conventional supports.

  • Patent number: 10258702
    Abstract: A water-absorbent carrier for moist heat sterilization can be used in a narrow space and does not have a risk of generating foreign matter. The water-absorbent carrier is obtained by embedding a water-absorbent substance in a synthetic resin. The water-absorbent carrier can be manufactured by impregnating the water-absorbent substance with a water-soluble substance, drying the water-absorbent substance, embedding the water-absorbent substance in a thermoplastic synthetic resin, and washing the water-absorbent substance to remove the water-soluble substance. Alternatively, the water-absorbent carrier can be manufactured by dispersing a water-insoluble synthetic resin in a dispersion medium, mixing the water-absorbent substance in the dispersion medium, pouring the mixture into a mold, and volatilizing the dispersion medium. A medical article to be sterilized includes the water-absorbent carrier packaged in a closed space.

  • Patent number: 10150848
    Abstract: Composite materials including cellulose nanocrystals incorporated into a polymer aerogel scaffold, wherein the cellulose nanocrystals serve as a reinforcement agent to result in the formation of less dense aerogels, improve the tensile mechanical properties of aerogel films, and reduce aerogel shrinkage upon thermal exposure. After gelation, the gel is dried via a suitable method such as supercritical CO2 extraction, freeze drying or other method, to produce the CNC/polymer composite aerogel. Properties of the composite aerogel can be tailored via surface modification of the cellulose nanocrystals as well as through the backbone structure of the polymer.

    Abstract: The present invention relates to a continuous manufacturing process for a rubber masterbatch and a rubber masterbatch prepared therefrom. The manufacturing process comprises the following steps: step 1): a filler is added to a rubber solution, forming a rubber/filler/solvent mixture by stirring; and step 2): the solvent is removed and the mixture is dried, resulting in a rubber/filler masterbatch. The present invention also relates to a masterbatch prepared by the above-mentioned process and a rubber article prepared using the masterbatch. Compared to the wet mixing technologies in the prior art, the present invention has no specific requirements of rubber and filler, with a wider scope of usage. In addition, the filler has a high dispersion in rubber compounds, the production process thereof is continuous, highly efficient, low in energy consumption and labour, and thus low in cost.
