Thermal decomposition of C60
TL;DR: In this article, the influence of heat treatment of C60 pellets in vacuum at temperatures between 500°C and 900°C has been investigated by a variety of experimental techniques and it is inferred that C60 decomposes into amorphous carbon on heat treatment at temperatures beyond 700°C.
Journal ArticleDOI
Pressure dependence of free-volume hole properties in an epoxy polymer
TL;DR: Positron annihilation spectroscopy has been applied to study free-volume properties in an amine-cured epoxy as a function of quasi-isotropic pressure in the range o-15 kbar.
Journal ArticleDOI
Superconductivity in Ru substituted polycrystalline BaFe 2-x Ru x As 2
Shilpam Sharma,A. Bharathi,Sharat Chandra,V. Raghavendra Reddy,S. Paulraj,A. T. Satya,V. S. Sastry,Ajay Gupta,C. S. Sundar +8 more
TL;DR: In this article, a phase diagram is proposed based on the measured spin-density-wave transition temperature and superconducting transition temperature as a function of Ru composition, which indicates weakening of magnetic interaction with Ru substitution.
Journal ArticleDOI
Effect of Ti and Cr on dispersion, structure and composition of oxide nano-particles in model ODS alloys
Andrew J. London,S. Santra,S. Amirthapandian,B. K. Panigrahi,R.M. Sarguna,S. Balaji,R. Vijay,C. S. Sundar,Sergio Lozano-Perez,C.R.M. Grovenor +9 more
TL;DR: In this paper, three model ODS alloys were prepared by ball milling and then hot extrusion to study the effect of Ti and Cr on the size, distribution, crystal structure and composition of the nano-oxide particles.
Journal ArticleDOI
Optical properties of CdS nanoparticles upon annealing
TL;DR: In this paper, the metastable cubic phase of CdS has been stabilized in the form of nanoparticles using X-ray diffraction (XRD), Raman, photoluminescence (PL) and infrared (IR) absorption spectroscopy.
