Immobilized lipase Novozym-435 catalyzed regioselective synthesis of glucose and undecylenic acid(UA) to produce glucose mono-ester in Organic solvents was investigated. Reactionconditions were tested in order to produce the mono-ester more rapidly and in higher yield, the optimal conditions were obtained as: temperature at 50°C,mole ratio of glucose toUA of 1:2,concentration of molecular sieves and enzyme used as 0.56mg/mL and 10mg/mL respectively . After the reaction, product was purified, and characterized by MS and 13C NMR spectroscopy, and determined as 6-O-(10-undercylenoyl)-D-glucose, The product was used as the starting material, K2S2O8 as a chemical initiator, to polymerize and form the sugar-containing polymer, which could be used for medicine release agent and other application of biological materials.

A kind of novel multifunctional ene bio-based oligomer has been successfully synthesized, which based on the renewable resource of the rapeseed oil and the 10-undecylenic acid. The structure of this novel oligomer was confirmed through proton nuclear magnetic resonanace (NMR). The result shows that the goal product has been produced successfully.

Stainless Steel Aisi

The synthesis and characterization of Ti and TiN thin films of different thicknesses was carried out on a martensitic stainless steel AISI 410 substrate used for tool manufacturing. The mechanical parameters between the interacting surfaces such as thickness, adhesion and hardness were measured. By means of the scanning electron microscope (SEM) the superficial morphology of the Ti/TiN interface was observed, finding that the growth was of columnar grains and by means of EDAX the existence of titanium was verified.  Using X-ray diffraction (XRD) it was possible to observe the presence of residual stresses (~ -3.1 GPa) due to the different crystalline phases in the coating. Under X-ray photoemission spectroscopy (XPS) it was possible to observe the molecular chemical composition of the coating surface, being Ti-N, Ti-N-O and Ti-O the predominant ones.
