Nickel catalyzed one pot synthesis of biaryls under air at room temperature
(Royal Society of Chemistry, 2013) Bhat, A.P.I.; Inam, F.; Badekai Ramachandra, B.
A practical, room temperature catalytic system has been developed for the synthesis of biaryls in one step from the homocoupling of in situ generated Grignard reagents using a nickel(ii) complex. The use of atmospheric oxygen as the oxidant makes the system environmentally friendly. The reaction system is compatible with diverse functionality to afford biaryls in appreciable yields. © The Royal Society of Chemistry 2013.
Porous MnO2 nano whiskers bunch/activated carbon based composite electrodes for high energy density supercapacitor
(2013) Aravinda, L.S.; Bhat, K.; Badekai Ramachandra, B.
A simple room temperature method was used to synthesize Porous ?-MnO2 nano whiskers bunch. The porous ?-MnO2 /Activated carbon (AC) composites were prepared by very simple mechanical mixing method with varying amount of MnO2. A symmetric supercapacitor stack was fabricated using the prepared composite electrode material. The composite with 30% MnO2 exhibit a maximum specific capacitance of 107 Fg-1 at 1 mAcm-2 in non-aqueous electrolyte. The corresponding energy density was found to be 8.35 Whkg-1. The electrode also exhibits excellent cyclic stability. © 2013 The Electrochemical Society.
