Hind Al-Johani,Hind Al-Johani,Edy Abou-Hamad,Abdesslem Jedidi,Abdesslem Jedidi,Cory M. Widdifield,Jasmine Viger-Gravel,Shiv Shankar Sangaru,David Gajan,Dalaver H. Anjum,Samy Ould-Chikh,Mohamed N. Hedhili,Andrei Gurinov,Michael J. Kelly,Mohamad El Eter,Luigi Cavallo,Lyndon Emsley,Jean-Marie Basset +17 more
TL;DR: 13C and 23Na NMR experiments show that Na+ ions are present near the gold surface, indicating that carboxylate binding occurs as a 2e- L-type interaction for each oxygen atom involved, which has broad potential to probe the binding of a variety of ligands to metal nanoparticles.
Journal ArticleDOI
Synthesis of highly stable silver nanoparticles by photoreduction and their size fractionation by phase transfer method
Prakash Kshirsagar,Shiv Shankar Sangaru,Maria Ada Malvindi,Luigi Martiradonna,Roberto Cingolani,Pier Paolo Pompa +5 more
TL;DR: In this article, a green chemical approach for the synthesis of stable silver nanoparticles in aqueous medium using tyrosine as an efficient photoreducing agent was demonstrated, and the size fractionation was achieved by a 2 stage phase transfer method employing different organic solvents.
Journal ArticleDOI
Surface Composition of Silver Nanocubes and Their Influence on Morphological Stabilization and Catalytic Performance in Ethylene Epoxidation
Shiv Shankar Sangaru,Zhu Haibo,Devon C. Rosenfeld,Akshaya K. Samal,Dalaver H. Anjum,Jean-Marie Basset +5 more
TL;DR: It is observed that the surface composition of the silver nanocubes also has a critical impact on activity, and the surface chloride is apparently essential for stabilizing the cubic morphology of the particles.
Journal ArticleDOI
Synthesis of fluorescent metal nanoparticles in aqueous solution by photochemical reduction
Prakash Kshirsagar,Shiv Shankar Sangaru,Virgilio Brunetti,Maria Ada Malvindi,Pier Paolo Pompa +4 more
TL;DR: Both silver and gold nanoparticles synthesized by this method exhibited fluorescence properties and their use for cell imaging applications has been demonstrated.
Journal ArticleDOI
The Synergetic Impact of Anionic, Cationic, and Neutral Polymers on VES Rheology at High-Temperature Environment
A A Othman,Mohammed Alsulaimani,Murtada Saleh Aljawad,Shiv Shankar Sangaru,Muhammad Shahzad Kamal,Mohamed E. Mahmoud +5 more
TL;DR: In this paper , a hydraulic fracturing fluid with exceptional rheological and thermal stability was designed by mixing zwitterionic VES with carboxymethyl cellulose (CMC), hydroxyethylcellulose (HEC), or a poly diallyl dimethylammonium chloride (DADMAC) polymers.
