Aesthetic evaluation of anterior teeth defect restored with fiber posts and resin cores;

Clinical applications of D T Light fiber post and resin core system;

Objective To explore the clinical effect of fiber post and resin core system.

Objective: To evaluate the fracture mode and the micromorphology of the bonding unit of the microtensile bond specimens of two types of core build-up composite (Ultrafine Diamond Core, UFD-C, Luxa Core, L-C) to three types fiber post in vitro.

Screening and Optimizing of Nuclear Grade Resin in TQNPC;

The complexes cross-linkswith EGBE as cross-linking agent under microwave irradiation,Zn 2+ being removed with dilute acid,a new cross-linked chitosan resin with Zn(Ⅱ) cavtitycan be synthesized.

In comparison with the cross_linked chitosan resin prepared by conventional heating, it has a better adsorption capacity for Cu 2+ , and shows very good stability and reusability unde.

Using Cu(Ⅱ) ion as template, a series of chitosan resins, with varied contents of template ion, were prepared by reacting chitosan(CTS) with crosslinking agent ethylene glycol bisglycidyl ether(EGBE), and their static adsorption properties such as adsorption capacities, kinetic and isotherm for Cu 2+ , Ni 2+ , Co 2+ were studi that.

A multi-functional composite, Co/N-TiO2 with core-shell structure was synthesized by two-step process.

Due to their uniform size and regularity in the structure,core-shell structure composite nanoparticles will exhibit unique properties in electromagnetism,optics and mechanism.
