Hydroxyapatite(HA) based materials have been widely used in the field of ligament tissue engineering in the past *** has been previously reported that HA can increase the penetration of marrow-derived mesenchymal stem cells(MSCs) and MSCs cells into scaffolds due to increased cell differentiation in biological ***,it was found that there are much difference between MSCs and anterior cruciate ligament (ACL) *** that reason,we mainly evaluate the biocompatibility of polyethylene terephthalate(PET) silk scaffold with fibroblasts cells in *** cultured mouse fibroblasts cells on the substrate of PET fiber and PET-HA scaffold,respectively,and then observed the morphology by using scanning electron *** data indicate that PET-HA scaffold has good biocompatibility with fibroblasts cells and can potentially be useful in enhancing the fibroblasts cell differentiation and proliferation.

High-resolution neutron powder diffraction has been performed to study the structural evolution of the perovskite KCuF3 at temperatures up to 900 K. Results of the Rietveld refinement reveal an unusual site distortion that increases as temperature increases. In contrast to the widely accepted assumption that a cooperative Jahn-Teller transition may occur at 800 K, no phase transition was observed up to 900 K. We have made a comparative study of the Jahn-Teller distortion in fluorides and oxides with variables such as temperature, pressure, and the dilution by non-Jahn-Teller active ions in these compounds.
We have improved the crystal growth methods of thiophene/phenylene co-oligomers (TPCOs). The crystal growth was carried out in a liquid phase. The resulting crystals were well defined in thin polygons with several pai...
