The invention disclosed a novel mesoporous silica-based xerogel and its use in hemorrhage control. The mesoporous silica-based xerogel material has tunable mesopores (1-50 nm), high specific surface area (100-1400 m.sup.2/g), macroscopical morphology (powder, film, disc, column, etc.) and adjustable compositions (SiO.sub.2, CaO and P.sub.2O.sub.5, etc.) as well as good biodegradation. The mesoporous silica-based xerogels herein effectively promote the blood clotting under various conditions including slow and severe hemorrhage, even at the blood oozing site of bone defect. Meanwhile, the networks of silica-based xerogel with good elastic and mechanic properties, formed by adsorbing a large amount of water, can modulate the cell behavior and tissue growth, and thus promote the wound healing. Additionally, due to the mesoporous structure, the materials have the potential to load drug, thrombin and bioactive factors, which is favorable for the therapeutical efficacy.

Nanometer mesoporous silica-based xerogel styptic process and its preparing process and application

The invention relates to daily necessities of life; and more particularly to a dentifrice powder that promotes oral health, and cleaning for the teeth and gums. One example includes the following ingredients: TABLE-US-00001 calcium carbonate 26-36 parts mineral powder 6-12 parts foaming agent 3-7 parts sodium benzoate 3-7 parts Chinese gall 1-3 parts hydrated amorphous silica 2-6 parts aromatic agent 1.5-2.5 parts wintergreen oil 1.5 to 2.4 parts sodium monofluorophosphate 17-22 parts calcium supplements 17-24 parts This dental powder provides the absorption of calcium and trace minerals by the teeth and gums, to promote microcirculation, reduce or eliminate periodontal sores, receding gums, loose teeth, gum bleeding, sensitivity to heat and cold, tooth decay, dental disease the breeding of bacteria, and oral inflammation; and to remove stains from the teeth, including cigarette smoke stain, coffee and tea stains, and black and yellow dye stains.

Oral dentrifice power and method

A resin does not need to incorporate a fluorescent substance and exhibits fluorescence itself. Also, a liquid crystal polymer is provided which does not contain a bleeding out substance such as hydrophobic silica and barium sulfate and which has an effect of suppressing fibrillation in the resin itself. A liquid crystal polymer includes a copolymer of a polymerizable monomer (A) selected from the group consisting of pyromellitic acid or anhydride thereof and a reactive derivative thereof and a polymerizable monomer (B).

The invention relates to spray-dried, washfast dye compositions, preferably in the form of pigment powders, having a bleeding rate of .ltoreq.0.5% and consisting of water-soluble functional dyes, preferably food dyes, which are firmly incorporated in a silica matrix. Apart from low bleeding of dye, these compositions are remarkable for their high stability to pH changes and/or ascorbic acid. The invention is also directed to the production of the dye compositions and the use thereof. The dye compositions are preferably employed in coloring foods, cosmetics, pharmaceutical products, but also in other uses.

The present invention provides less expensive ink jet recording papers having high glossiness and high durability and being capable of quickly absorbing inks without causing bleeding. Accordingly, the present invention provides an ink jet recording paper having an ink-receiving layer provided on a porous resin film, wherein the porous resin film has a liquid absorption capacity measured in accordance with "Japan TAPPI No.51-87" of 0.5 ml/m2 or above and the ink-receiving layer has a surface glossiness (JIS-Z8741: measuring method at 60.degree.) of 40% or above. It is preferable that the ink jet recording paper contains at least one member selected from among alumina, alumina hydrate and amorphous silica in the ink-receiving layer.
