nanoparticles). In the present work, Tio2 Nano particles have been synthesized by Sol-gel technique. The Prepared
powders were characterized by using XRD, SEM. The Crystalline size of TiO2 powder was found to ~6 nm for
anatase at 400 ºC by controlling the acidity. TiO2 water nanofluids with different volume concentrations from 1% to
2% were then prepared by dispersing the synthesized Nano particles in deionised water

ultrafine or nanometric metallic or ceramic particles in a given fluid. Nanofluids possess
immense potential of application to improve heat transfer and energy efficiency in several areas
including vehicular cooling in transportation, power generation, defense, nuclear, space,
microelectronics and biomedical devices. In the present contribution, a brief overview has been
presented to provide an update on the historical evolution of this concept, possible synthesis
routes, level of improvements reported, theoretical understanding of the possible mechanism of
heat conduction by nanofluid and scopes of application. According to this review, the future
developments of these technologies are discussed. In order to put the nanofluid heat transfer
technologies into practice, fundamental studies are greatly needed to understand the physical
mechanisms.

of motor vehicles and the combustion of fossil fuels. Pollution control is the very important role for future generation to control
toxic emissions like CO, NOX and HC. The objective of the work is to reduce the emissions from the automobiles through
design and manufacturing of nano catalytic converter by replacing the existing expensive metals such as platinum, cerium
oxide. Nano materials like nano rhodium and nano palladium were obtained by using chemical vapour deposition (CVD)
technique. The obtained nano powder was deposited in the honey comb structure by using spin coating method. Further the
characterization of nano palladium and nano rhodium powder is made through scanning electron microscope, X-ray diffraction,
transmission electron microscope. By using the nano catalytic converter the pollution is reduced."

The study presents the synthesis of nanosized TiO2 powder with anatase structure was derived from sol-gel process. Data concerning the effect of pH towards the development of TiO2 nanoparticles is reported. The samples were examined by SEM- EDAX, XRD, and FT-IR analysis. Surface morphological studies obtained from SEM micrograph. The Crystalline size of TiO2 powder has obtained for (i) pH 2 is ~3nm (ii) pH 4 is ~ 6nm at 400 ºC by controlling the acidity. In FT-IR, all the peaks observed were around 460-560 cm-1 due to stretching and bending vibrations of -OH groups. It was also found the pH of the solution affect the agglomeration of the particles
