PhD Topic: Development of Nano-TiO2/Y2O3 Dispersed Zirconium Alloys by Mechanical Alloying Followed by Conventional and Spark Plasma Sintering Description: Zirconium based alloys are attractive materials for high temperature applications mainly in the chemical and nuclear sectors due to their excellent corrosion resistance, good mechanical and thermal properties with very low neutron absorption. Minor addition of nano oxides in zirconium matrix enhances mechanical properties by dispersion strengthening and its grain boundary pinning results in better high temperature stability. Moreover nano-sized oxide dispersion in the alloy suppresses the grain growth during annealing at high temperature results in the improvement of creep strength. The elevated temperature yield strength and corrosion resistance of zirconium alloys can be increased by dispersion of nano-TIO2/Y2O3. X-ray diffraction and TEM analysis reveal formation of different intermetallics of 10-30 nm size along with TiO2/Y2O3 (10-20 nm) throughout the matrix. Alloys consolidated by spark plasma sintering was found to possess high levels of compressive strength (825-1240 MPa) and hardness

(10.38-16.85 GPa) which was 1.5-2 times higher than that obtained from conventional sintering. Addition of TiO2 and Y2O3 helps in enhancement of mechanical properties and effect of TiO2 was more prominent.Y2O3 dispersion displays better corrosion resistance, whereas, base alloy shows best oxidation property.

M.Tech Project Topic: Preparation and Characterization of Nanostructured Zinc Selenide Thin Film.

Description: Zinc Selenide (ZnSe) is an important opto-electronic semiconducting material with a wide band gap of 2.7 eV. Even though many techniques are used for the preparation of ZnSe thin films, electrochemical deposition from aqueous solution attracts much attention in recent years, due to its low cost and ability to control the film properties by varying the deposition parameters. A nanocrystalline thin film of ZnSe was successfully electrodeposited on a copper substrate using a non-aqueous solution. X-ray diffraction analysis confirmed the deposition of crystalline ZnSe with a 12 nm crystallite size. Scanning electron microscopy and atomic force microscopy studies revealed a densely packed non-porous granular deposit. The Schottky diode characteristic corroborated a typical semiconducting behaviour of ZnSe deposit. The band gap

(2.71 eV) obtained through spectroscopic analysis and the measured resistivity (1.5 Ω cm) were also in good agreement with the reported data of semiconducting ZnSe. Journal Publication
