Journal ArticleDOI
Synthesis and characterization of nanocrystalline thoria obtained from thermally decomposed thorium carbonate
Sitaram Dash,Alok Singh,P.K. Ajikumar,H. Subramanian,M. Rajalakshmi,A.K. Tyagi,Akhilesh K. Arora,S.V. Narasimhan,Baldev Raj +8 more
TL;DR: In this paper, the structural and stoichiometric changes encountered in the decomposition pathway were studied by off-line thermogravimetry (TGA), X-ray diffraction and Xray photoelectron spectroscopy (XPS), and accurate conversion temperature for transformation of Th(CO 3 ) 2 → ThO 2 was arrived from the XPS measurements.
Journal ArticleDOI
Evolved Gas Analysis by Mass Spectrometry
TL;DR: In this article, a quadrupole mass spectrometer based evolved gas analyser has been built in a laboratory with necessary UHV hardware, computer interface and software for conducting real-time multiple ion detection over a wide dynamic pressure regime.
Journal ArticleDOI
Lubrication properties of chemically aged reduced graphene-oxide additives
Bhavana Gupta,Bhavana Gupta,Niranjan Kumar,Kozakov Alexey Titovich,Kolesnikov Vladimir Ivanovich,Sidashov Andrey Vyacheslavovich,Sitaram Dash +6 more
TL;DR: In this article, the evidence of adsorbed graphite tribo-species in the wear track is observed by X-ray photoelectron spectroscopy (XPS) and micro Raman spectrographs.
Journal ArticleDOI
Improvement in tribological properties by modification of grain boundary and microstructure of ultrananocrystalline diamond films.
Kamatchi Jothiramalingam Sankaran,Niranjan Kumar,Joji Kurian,Radhika Ramadoss,Huang-Chin Chen,Sitaram Dash,A.K. Tyagi,Chi-Young Lee,Nyan-Hwa Tai,I-Nan Lin +9 more
TL;DR: The improved tribological properties of films can make it a promising candidate for various applications, mainly in micro/nanoelectro mechanical system (M/NEMS), where low friction is required for high efficiency operation of devices.
Journal ArticleDOI
Room temperature H2 sensing using functionalized GaN nanotubes with ultra low activation energy
TL;DR: In this article, a single-step synthesis route of square shaped wurtzite GaN nanotubes is reported by a quasi-vapor-solid process with detailed growth kinetics involving surface energies and Ga mobility along different crystalline facets.
