Journal ArticleDOI
Nano-welding and junction formation in hydrogen titanate nanowires by low-energy nitrogen ion irradiation.
Satyanarayan Dhal,Shyamal Chatterjee,Subhrangsu Sarkar,Lokesh C. Tribedi,Rudheer D. Bapat,Pushan Ayyub +5 more
TL;DR: While ion-irradiation induced defect formation and dangling bonds may lead to chemical bonding between nanowires, the large scale nano-welding and junction network formation can be ascribed to localized surface melting due to heat spike.
Journal ArticleDOI
Hot ion generation from nanostructured surfaces under intense, femtosecond irradiation
Suman Bagchi,P. Prem Kiran,Manoj Kumar Bhuyan,Shikha Bose,Pushan Ayyub,M. Krishnamurthy,G. Ravindra Kumar +6 more
TL;DR: In this paper, the effect of a nanostructured surface on the emission of ions and electrons from intense femtosecond laser produced plasmas was investigated, and it was observed that ion yields from optically polished copper targets coated with copper nanoparticles (CuNP) were hotter than those from uncoated polished targets.
Journal ArticleDOI
In situ monitoring of electrical resistance of nanoferrite thin film irradiated by 190 MeV Au14+ ions
TL;DR: In this article, a highly resistive nanocrystalline thin film of Li0.25Mg0.5Mn0.1Fe2.15O4, deposited by RF magnetron sputtering technique on Si(1/0/0) substrate, is irradiated with 190 MeV Au14+ ions.
Journal ArticleDOI
Secondary recrystallization during sintering of YBa2Cu3O7−gd derived from water-in-oil microemulsion
Pushan Ayyub,Manu Multani +1 more
TL;DR: In this article, the authors report the occurrence of secondary recrystallization (exaggerated grain growth) during the sintering of YBa 2 Cu 3 O 7−δ synthesized from a water-in-oil microemulsion system.
Journal ArticleDOI
Preferential enhancement of laser-driven carbon ion acceleration from optimized nanostructured surfaces
Malay Dalui,Wei-Min Wang,Wei-Min Wang,Wei-Min Wang,T. Madhu Trivikram,Subhrangshu Sarkar,Sheroy Tata,J. Jha,Pushan Ayyub,Zheng-Ming Sheng,Zheng-Ming Sheng,M. Krishnamurthy +11 more
TL;DR: An experimental demonstration of how the nanostructuring of a copper target can be optimized for enhanced carbon ion acceleration over protons or Cu-ions using particle-in-cell simulations.
