Abstract:
Provided is a formulation for oral teeth, which includes a plurality of calcium ion carriers and a plurality of calcium-containing particulates. The particulates are carried by the calcium ion carriers, such that the formulation can prevent or rapidly treat dentin-associated symptoms or diseases, while providing a prolonged prophylactic or therapeutic effect.
Abstract:
The invention provides a nanostructure material with metallic oxide including a product fabricated by the following steps: condensing silicon oxide or titanium oxide with a surfactant, obtaining a mesoporous silicon oxide or titanium oxide; mixing the mesoporous silicon oxide or titanium oxide with a metal or metallic compound and subjecting the mixture to a heterogeneous nucleation. According to another embodiment of the invention, the nanostructure material can also be fabricated by the following steps: subjecting silicon oxide or titanium oxide and a carbon black template to a calcination; mixing the results with a metal or metallic compound; and subjecting the mixture to a second calcinations. Further, in the invention, a method for detecting phosphorus-containing compounds employing the aforementioned nanostructure material is also provided.
Abstract:
The present invention relates to a method for synthesizing mesoporous aluminosilicate or pure-silica molecular sieves with newly hierarchical morphologies by adding suitable amount of alcohol. There are hollow sphere, hollow sphere with a pillar in it and solid sphere by adjusting the Al2O3/SiO2 and tetraethylorthosilicate/SiO2 ratio. The wall of the micron-sized spherical structure consisted of well-ordered cylindrical pores of nanometer size. The dimensions and the morphologies of the mesoporous structure are adjustable by varying the reaction components as the water content, the silicon/surfactant ratio and the reaction and the hydrothermal temperature.

Abstract:
The present invention relates to a method for synthesizing mesoporous aluminosilicate and pure silica molecular sieves of new micro-tubular morphology. The wall of the microtubules contains coaxial cylindrical pores of nanometer size. The diameter of the hollow tubular is adjustable from 0.1 to 3 micrometer by varying the reaction conditions such as the surfactant/water ratio, the addition of salts or cosurfactants, the surfactants with different carbon chain length and the silicon/aluminum ratio.
