A novel nanocomposite coating containing titania, silica and lanthanum phosphate prepared through an all aqueous sol-gel route exhibits excellent self-cleaning ability arising from the synergistic effect of the constituents in the nanocomposite. A highly stable titania-silica-lanthanum phosphate nanocomposite sol having particle size in the range of 30-50 nm has been synthesized starting from a titanyl sulphate precursor, which was further used for the development of photocatalytically active composite coatings on glass. The coatings prepared by the dip coating technique as well as the nanocomposite powders are heat treated and characterized further for their morphology and multifunctionality. The nanocomposite containing 1.5 wt% LaPO4 has shown a surface area as high as 138 m(2) g(-1) and a methylene blue degradation efficiency of 94% in two hours of UV exposure. The composite coating has shown very good homogeneity evidenced by transparency as high as 99.5% and low wetting behaviour. The present novel approach for energy conserving, aqueous derived, self-cleaning coatings may be suitable for large scale industrial applications.

This article showcases a new unique high gain step up DC/DC converter which is the future of interfacing to fully green electric vehicle scheme. This technique optimally integrates four diodes, three capacitors and a modified coupled inductor connected to electric vehicle motor, which is three -phase Brushless DC motor. The developed converter topology has reduced conduction losses, improved the conversion range, functionality with switched capacitor method with which reduced voltage stress during the switching period of the converter is achieved. Due to utilization of energy from leakage inductance of the new topology, mutually joined inductor will support to improve the efficiency and power concentration. Also, grouping of parallel inductor and diode L-D in series with the power switch helps in decreasing the switching stress current. When compared to existing converter topologies, the developed converter topology helps to produce output voltage of 505V for an input DC voltage of 30V, improved the voltage gain to 16.8 achieving the output power of 525W and efficiency to 97.74%. The voltage stress on the switch, diode and capacitor is 170 V, which is 34 % of the converter output voltage. The designed converter is simulated using MATLAB/Simulink and the performance of the new topology is compared with different converter topologies.
