In this paper the Nanostructured surface layer was first produced on the Ti-6Al-4V alloy by SMAT technique, and then the compound ceramic coatings of surface SNC/MAO were prepared on the nanocrystallized surface of Ti-6Al-4V alloy by MAO, and the phase composition and structure, morphology and the analysis of the elements were discussed.

Introduction Hydroxyapatite(HA) has been extensively studied for its chemical composition and crystallographic structure similar to those of human hard tissues [1-4].
Conclusions The surface topography and chemistry of the substrate can affect the osteoblastic cell attachment, proliferation and differentiation.

Theoretical analysis and simulation results show that the improved Elman NN for nitride hardening has the advantage of identifying non-linear dynamic systems, while it does not need any prior knowledge of their orders and structures.

Molecular structure of imidazolium-based ionic liquid crystals.
Here, we designed and synthesized two kinds of imidazolium-based ionic liquid crystal (Fig. 1) using a microwave-assisted method, which was introduced different R groups (alkyl system), through recent developments in aromatic amination chemistry [9].
