Halogen-free bis(salicylato)borate anion based ionic liquids having imidazolium and ammonium cations, were designed, synthesized, characterized then evaluated as potential lubricant additives. Owing to the high polarity, London dispersive forces rigidity associated with bulk size ring structure of anion, these possess very viscosities. The interaction contact surfaces has been found be strongly influenced by van der Waals interactions in liquids, which increases an increase alkyl chain...
A rhenium-oxo complex such as methyltrioxorhenium (MTO) has been homogeneously immobilized on a Schiff base modified graphene oxide (GrO) support via covalent bonding. The loading of MTO GrO nanosheets was monitored by FTIR, TG-DTA, and elemental analyses. developed heterogeneous catalyst is found to be efficient for the oxidation various amines corresponding N-oxides using hydrogen peroxide an oxidant in high excellent yields. At end reaction, readily recovered filtration reused subsequent...
The present work addresses the synthesis and application of graphene‐based ternary nanocomposite for anticorrosion performance to protect mild steel in an accelerated corrosive environment. chemically‐functionalized graphene‐nickel oxide (Gr‐NiO)‐PANI is synthesized by hydrothermal reduction graphene (GO) nickel salt presence urea, followed interfacial wrapping Gr‐NiO situ grown polyaniline (PANI). transmission electron microscopic images reveal PANI Gr‐NiO‐PANI nanocomposite. spectroscopic...
Laser surface melting (LSM) of Ti—6Al—4V is performed in argon to improve its properties, such as microstructure, corrosion, and wear for biomedical applications. Corrosion behavior investigated by conducting electrochemical polarization experiments simulated body fluid (Ringer's solution) at 37 C. Wear properties are evaluated Ringer's solution using pin-on-disc apparatus a slow speed. Untreated contains α+β phase. After laser melting, it transforms acicular α embedded the prior β matrix....
Evaporation residue cross sections and spin distributions have been measured for $^{200}\mathrm{Pb}$ compound nucleus formed in $^{16}\mathrm{O}+^{184}\mathrm{W}$ reaction at the laboratory beam energies of 84, 92, 100, 108, 116, 120 MeV. The evaporation residues selected using recoil mass spectrometer, HIRA detected a 2D position sensitive silicon detector. by detecting gamma rays with 14 element BGO multiplicity filter. Measured are compared values predicted standard statistical model...
Fission fragment mass ratio distributions have been measured for the reactions $^{16}\mathrm{O}+^{194}\mathrm{Pt}$ and $^{24}\mathrm{Mg}+^{186}\mathrm{W}$, both leading to same compound nucleus, $^{210}\mathrm{Rn}$, at near-barrier energies. The fission variances $^{24}\mathrm{Mg}+^{186}\mathrm{W}$ are compared with calculations assuming nucleus formation. Mass of fragments from reaction show a dramatic deviation behavior. This suggests strong evidence onset quasifission process in this reaction.
We report here measurements of fusion cross-sections for the ${}^{16}\mathrm{O}{+}^{112,116}\mathrm{Sn}$ and ${}^{32}\mathrm{S}{+}^{112,116,120}\mathrm{Sn}$ systems. The set systems studied with widely varying ground state Q values transfer neutrons is a good case to understand influence single multineutron on process. evaporation residue were measured in small energy steps covering region around Coulomb barrier $(\ensuremath{\approx}{0.8V}_{b}$ ${1.2V}_{b}).$ data have been analyzed...
