  • Carbon-supported Pt-Fe alloy as a methanol-resistant oxygen-reduction catalyst for direct methanol fuel cells 
    Shukla, A.K.; Raman, R.K.; Choudhury, N.A.; Priolkar, K.R.; Sarode, P.R.; Emura, S.; Kumashiro, R. (Journal of Electroanalytical Chemistry. 563(2); 2004; 181-190.)
    Crossover of methanol from the anode to the cathode through the polymer-electrolyte membrane in solid-polymer-electrolyte direct methanol fuel cells constitutes a significant loss in their performance. Pt/C and Pt-Fe/C ...
  • Carbonyl-iron electrodes for rechargeable-iron batteries 
    SundarRajan, A.; Ravikumar, M.; Priolkar, K.R.; Sampath, S.; Shukla, A.K. (Electrochemical Energy Technology. 1(1); 2015; 2-9.)
    Nickel-iron and iron-air batteries are attractive for large-scale-electrical-energy storage because iron is abundant, low-cost and non-toxic. However, these batteries suffer from poor charge acceptance due to hydrogen ...
  • In situ crystallographic probing on ameliorating effect of sulfide additives and carbon grafting in iron electrodes 
    Ravikumar, M.K.; SundarRajan, A.; Sampath, S.; Priolkar, K.R.; Shukla, A.K. (Journal of the Electrochemical Society. 162(12); 2015; A2339-A2350.)
    Beneficial effects of carbon grafting into the iron active material for rechargeable alkaline-iron-electrodes with and without Bi2S3 additive is probed by in situ X-ray diffraction in conjunction with Extended X-ray ...
  • Oxide-ion conductivity in Cu(x)Ce(1-x)O(2-delta) (0 less than or equal to x less than or equal to 0.10) 
    Gayen, A.; Priolkar, K.R.; Shukla, A.K.; Ravishankar, N.; Hegde, M.S. (Materials Research Bulletin. 40(3); 2005; 421-431.)
    Up to 10 at. percent of copper readily substitutes for cerium in ceria. It is found that at oxygen partial pressures between 0.21 atm and 10(-5) atm, Cu(x)Ce(1-x)O(2-delta) (0 less than = x less than = 0.10) solid solution ...
  • Tailoring a Pt-Ru catalyst for enhanced methanol electro-oxidation 
    Raman, R.K.; Shukla, A.K.; Gayen, A.; Hegde, M.S.; Priolkar, K.R.; Sarode, P.R.; Emura, S. (Journal of Power Sources. 157(1); 2006; 45-55.)
    A carbon-supported (1:1) Pt-Ru (Pt-Ru/C) alloy catalyst has been prepared in-house by the sulfito-complex route, and has been tailored to achieve enhanced activity towards methanol electro-oxidation by annealing it at ...
