BACKGROUND Endothelial cells play an important role in the delivery of cells to the inflammation site, chemotaxis, cell adhesion and extravasation. Implantation of a foreign material into the human body determines inflammatory and repair reactions, involving different cell types with a plethora of released chemical mediators. The evaluation of the interaction of endothelial cells and implanted ...

Many techniques for the surface modification of titanium and its alloys have been proposed from the viewpoint of improving bioactivity. This paper contains an overview of surface treatment methods, including coating with hydroxyapatite (HAp), an osteoconductive compound. There are two types of coating methods: pyroprocessing and hydroprocessing. In this paper, hydroprocessing for coating on the...

The structure and growth of thin films of titanium on α−Al2O3 at room temperature were investigated though in situ RHEED observations. Two different structures coexists at low coverage. One corresponds to the Ti(0001) ‖ Al2O3(0001), Ti[1100] ‖ Al2O3[2110] and Ti[1010] ‖ Al2O3[1100] epitaxy of the α phase of titanium reported before for thick films prepared at high temperature. The other structu...

Through kinetic analysis, we demonstrate that the formation of catalyst and substrate reservoirs plays a crucial role in titanium(III)-catalyzed ketone-nitrile coupling reaction. Together with insight from previous studies, model is assembled reflects observed influence ZnCl2 Et3N byproducts as well hydrochloride additive, which employed frequently titanium(III) catalysis. We further propose fo...

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

In this paper, based on numerical study using Finite Difference Time Domain method, we discuss two possible illumination schemes utilizing surface plasmon effects to achieve high density sub-100 nm scale photolithography by using ultraviolet light from a mercury lamp. In the illumination schemes discussed in this paper, a thin film layer, named as shield layer, is placed in between a photoresis...

Physicochemical properties of thin films on the base titanium oxides, obtained by a cathodic arc evaporation surface glass substrate are analysed in details. The analysis these was made using XRD, FTIR, SEM, XPS and ellipsometry. On basis analyses, particularly XPS, oxidative state Ti corresponding phases determined through various film layers from to substrate. depth levels their extinction co...
