Carbon Energy, EarlyView.ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Chemistry – A European Journal, EarlyView.The axial‐bonding of aluminum(III) porphyrins was used to create two covalently linked special‐pair mimics to probe charge‐transfer between a porphyrin dimer and a C60 unit for artificial photosynthesis. Although excitonic coupling between the porphyrins is weak, incorporation of a second porphyrin markedly increases both the yield and lifetime of the ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).
