Ab Initio Modeling of the ZnO-Cu(111) Interface
(American Chemical Society, 2021-12-31)The morphology at the catalytically active interfacial site of ZnO/Cu in the commercial ZnO/Cu/Al2O3 catalyst for CO2 hydrogenation to methanol is still an open question. In the present study, we employ ab initio density ... -
Axial distribution of plasma fluctuations, plasma parameters, deposition rate and grain size during copper deposition
(Taylor and Francis Inc., 2017)Floating potential fluctuations, plasma parameters and deposition rate have been investigated as a function of axial distance during deposition of copper in direct current (DC) magnetron sputtering system. Fluctuations ... -
Brevundimonas diminuta MYS6 associated Helianthus annuus L. for enhanced copper phytoremediation
(Elsevier Ltd, 2020-08-31)Natural occurring metal-tolerant microbial population have replaced conventional expensive metal remediation approach since the last few years. The present study focuses on investigating the potential of a copper-tolerant ... -
Chitosan-supported copper as an efficient and recyclable heterogeneous catalyst for A3/decarboxylative A3-coupling reaction
(Elsevier Ltd, 2018)Chitosan-supported copper (chit@copper) based heterogeneous catalysts have been explored for A3-coupling and decarboxylative A3-coupling. The developed protocol employs low catalyst loading, solventless condition and easy ... -
Direct Michael addition/decarboxylation reaction catalyzed by a composite of copper ferrite nanoparticles immobilized on microcrystalline cellulose: an eco-friendly approach for constructing 3,4-dihydrocoumarin frameworks
(Royal Society of Chemistry, 2022-10-27)A composite of copper ferrite oxide nanoparticles immobilized on microcrystalline cellulose (CuFe2O4@MCC) was synthesized. The synthesized composite was characterized by FESEM with EDS-Mapping, TEM, P-XRD, TEM, and BET ... -
Diselenophosphate-Induced Conversion of an Achiral [Cu20H11 {S2P (OiPr) 2} 9] into a Chiral [Cu20H11 {Se2P (OiPr) 2} 9] Polyhydrido Nanocluster.
(Wiley, 2015)A polyhydrido copper nanocluster, [Cu20H11{Se2P(OiPr)2}9] (2H), which exhibits an intrinsically chiral inorganic core of C3 symmetry, was synthesized from achiral [Cu20H11{S2P(OiPr)2}9] (1H) of C3h symmetry by a ligand?exchange ... -
Does Water Play a Crucial Role in the Growth of ZnO Nanoclusters in ZnO/Cu Catalyst?
(American Chemical Society, 2023-05-04)The catalytically active configuration of ZnO/Cu in the commercial ZnO/Cu/Al2O3 catalyst for methanol synthesis from CO2 is still not clear. In this study, we employ density functional theory based methods to shed light ... -
Evaluation of mycelial nutrients, bioactive compounds, and antioxidants of five Himalayan entomopathogenic ascomyceteous fungi from India
(Begell House Inc., 2015)In this study, using standard methods, mycelial nutrients, bioactive compounds, and antioxidants were analyzed for the first time for five fungal species: Isaria sinclairii (Berk.) Lloyd, I. tenuipes Peck, I. japonica ... -
Facile synthesis of alkyl- and arylboronate esters enabled by a carbon nanotube supported copper catalyst
(Royal Society of Chemistry, 2022-11-15)An efficient synthesis of alkylboronate esters via alkyl halide borylation catalysed by copper nanoparticles stabilised on nitrogen-doped carbon nanotubes (N-CNT) is reported. This nanocatalyst provides practical access ... -
Influence of anion induced proton abstraction on Cu(II) adsorption by alginic acid
(Elsevier B.V., 2015)Alginic acid (AA) synthesized by acidification of commercial sodium alginate was investigated for its Cu(II) adsorption efficiency in the presence of different counter ions. The results of batch adsorption studies indicated ...
