A thermoelectric material Smx Co4Sb12 （0（ x ≤1.0） is synthesized at high pressure and high temperature leading to an enhanced power factor. The experimental measurements show that the SmxCo4Sb12 compounds exhibits n-type conduction. The absolute value of the Seebeck coefficient decreases with increasing Sm fraction. The resistivity increases with samarium content x from 0.1 to 0.2, but decreases dramatically when x changes from 0.2 to 1.0. The maximum power factor reaches 13.1 μ***^-1K-2 at x =1.0, which is larger than the data previously reported for the La-doped CoSb3 prepared at room pressure.

A new route to synthesize TS-1 has been developed using the supercritical carbon dioxide（SCCO2） as a crystallization-assistant agent. SCCO2 plays a dual role： as a reagent changing the alkalinity during the crystallization process and as a medium eliminating mass-transfer limitations（both within the bulk fluid and through liquid/gas, solid/gas or solid/liquid phase boundaries）. In this route, it was shown that the Ti content in TS-I increase compared with that in the TS-1 prepared without SCCO2, but decrease while the SCCO2 pressure increase. The prepared crystal morphology also underwent significant change. The crystallization time of TS-1 can be shorten a lot.

The stability parameters of implants （ITV, ISQ ＆ PTV） according to different sizes of controlled bone defects made in implant osteotomies were analyzed and the correlation among the three kinds of implant stability parameters was tested in this study. 45 tapped screw-type dental implants were inserted in three types of implant osteotomies made in 8 fresh-frozen pig femoral bones： Typel - without coronal bone defect, Type2 - with 3 mm coronal bone defects, and Type3 - with 6 mm coronal bone defects. The insertion torque values, ISQ ＆ PTV of implants were measured and analyzed statistically. It is concluded that the circumferential coronal bone defects statistically influence the primary stability of implants; ITV, ISQ and PTV are suitable and available to detect the peri-implant coronal bone defects in 3 mm increments, and ITV and PTV are more sensitive to coronal cortical bone loss. There was a strong correlation between ITV and ISQ.
