Journal ArticleDOI
ZnO tetrapods and activated carbon based hybrid composite: Adsorbents for enhanced decontamination of hexavalent chromium from aqueous solution
Mahima Sharma,Monika Joshi,Subhasha Nigam,Sindu Shree,D.K. Avasthi,Rainer Adelung,Sanjeev Kumar Srivastava,Yogendra Kumar Mishra +7 more
TL;DR: In this paper, a tetrapodal ZnO was synthesized by flame transport synthesis (FTS) approach and activated carbon (AC) was successfully prepared from sugarcane bagasse with sodium hydroxide (NaOH) impregnation, followed by carbonization.
Journal ArticleDOI
Test of the hypothesis of transient molten state diffusion for swift-heavy-ion induced mixing
Sanjeev Kumar Srivastava,D.K. Avasthi,Walter Assmann,Zhikun Wang,H. Kucal,E Jacquet,H. D. Carstanjen,Marcel Toulemonde +7 more
TL;DR: In this article, the authors used elastic recoil detection analysis to determine the experimental intrinsic diffusivities of Fe in Si and vice versa, and the required size and duration of the transient melt phase have been calculated theoretically from the thermal spike model.
Journal ArticleDOI
Effect of grain size and microstructure on radiation stability of CeO2: an extensive study
Vinita Grover,Rakesh Shukla,Renu Kumari,Balaji P. Mandal,Pawan K. Kulriya,Sanjeev Kumar Srivastava,Santanu Ghosh,A. K. Tyagi,D. K. Avasthi +8 more
TL;DR: Ceria samples sintered under different conditions were irradiated with high energy 100 MeV Ag ions and Raman spectroscopy indicated the enhanced formation of Ce(3+) and related defects in the sample with larger grain size after irradiation.
Journal ArticleDOI
Size-dependent structural and magnetic properties of disordered Co2FeAl Heusler alloy nanoparticles
TL;DR: In this article, the effect of the size of nanoparticles on the structure and magnetization of Co2FeAl nano-alloy was investigated and the effects of particle size on hysteresis losses were discussed.
Journal ArticleDOI
Transient enhanced diffusion of oxygen in Fe mediated by large electronic excitation
D.K. Avasthi,Walter Assmann,Ambuj Tripathi,Sanjeev Kumar Srivastava,Santanu Ghosh,Florian Grüner,Marcel Toulemonde +6 more
TL;DR: In this paper, the incorporation of oxygen in a thin Fe film during its irradiation with swift heavy ions was observed, and it was observed that the adsorbed oxygen diffuses in to the Fe film.
