Ba0.5Sr0.5TiO3 thin films have been deposited by sol–gel spin coating technique and effect of pH of the precursor sol on the electrical and optical properties has been investigated. Thin films of...
Effect of Li+ doping on ZrO2–TiO2 humidity sensor (1999)
Jain, M K, Bhatnagar, M C, Sharma, G L
Humidity sensors are widely used in domestic and industrial environments. The authors have investigated 0.5ZrO2–0.5TiO2 ceramic for its humidity sensing electrical properties at room temperature....
Improvement of the oxygen gas sensitivity in doped TiO2 thick films (1999)
Sharma, Rajnish K, Bhatnagar, M C
The titania (TiO2) thick films were prepared by using screen-printing technology of 0.00, 0.20 and 0.40 wt.% Nb and 0.40 wt.% Cr concentration on alumina substrate. These thick films were sintered at...
Surface Composition and Microhardening in Nitrogen and Boron Implanted Nimonic-90 Alloy. (1998)
Goel, A. K., Sharma, N. D., Mohindra, R. K., Ghosh, P. K., Bhatnagar, M. C.
Strain induced and excess strain-free surfaces of Nimonic-90 alloy were studied following N2+ and 11B+ ion implantation. The energy of the ions was 130 keV at a dose of 2.5 x 1021 ions/m2. Techniques...
Shrivastava, Sadhna, Tarey, Ram D., Bhatnagar, M. C., Jain, Amitabh, Chopra, K. L.
Nitrogen ion implantation has proved effective in the surface strengthening of metals and alloys. In order to achieve high throughputs industrially, high beam currents must be used. The resulting...
Mechanism in Nb doped titania oxygen gas sensor (1998)
Sharma, R K, Bhatnagar, M C, Sharma, G L
Doping in titania (TiO2) with pentavalent Nb+5 metal ion has shown significant enhancement in the sensitivity which is about 65 times higher than the undoped material at lower operating temperatures....
Aggarwal, Sanjeev, Goel, A K, Mohindra, R K, Ghosh, P K, Bhatnagar, M C
The influence of nitrogen ion implantation on the surface characteristics of AISI 316 stainless steel has been examined on two different surfaces of the substrate: strain-induced (mechanically...
Surface analysis of a black copper selective coating (1991)
Bhatnagar, M C, Richharia, Purnima, Chopra, K L
This paper presents the surface analysis of a black copper selective coating using AES and XPS techniques. This study indicates that the textured black copper selective coating is a multiphase...
