Ruthenium oxide, Manganese oxide and (Ru:Mn)O2 composite thin films have been prepared by 0.02M Ruthenium chloride and Manganese acetate solutions respectively on stainless steel substrates by sol-gel spin coating method. Layer by layer deposition of RuO2 and MnO2 was done for composite films. RuO2: MnO2 composite thin films have been demonstrated to be an excellent material for Supercapacitor application when evaluated with RuO2 and MnO2 thin film electrodes with respect to XRD, SEM, CV, CP and EIS studies. As a result, high specific capacitance of 515 F/g at 10 mV/s with excellent stability and long cycle life was obtained, where specific power and energy were as high as 15.38 Wh/kg and 4.06 KW/kg respectively with loading weight of 0.13 mg/cm2 .Composite films showed changes in structural and morphological features which was admiring for supercapacitor applications. The electrochemical impedance measurement was carried out in 0.1M KOH in the frequency range 10 to 105 Hz. From the analysis it can be concluded that mixed oxide composites have superior capacitive performance to single transition metal oxides as electrodes.

Nanometer TiO2 microcapsule has potential applications in biochemistry, drug Controlled Release, and catalyst. Meanwhile, Ultraviolet (UV) light-induced bioactivity of titanium substrates is attracting more and more attention nowadays. Composite thin films formed by Nano-TiO2 microcapsule prepared by a novel and versatile technique of layer-by-layer (L-b-L) deposition using the Nanometer latex particles of Polystyrene (PS) as the template together with TiO2 films synthesized at low temperature by the hydrolysis of titanium chloride (TiCl4) precursor was successfully deposited on the different titanium substrates after the template was removed. Thus great expectation was placed on whether UV radiation can enhance the bioactivity of the titanium substrates after the composite thin films being deposited on its surface. The apatite-forming ability was evaluated after the UV-irradiated implants being soaked in simulated body fluid (SBF) within different hours by Scanning electron microscopy (SEM), XRD. The vitro results indicated that UV radiation was favored to formation of apatite on titanium substrates. Besides, the effect of different UV- irradiation time on apatite-forming was different.
