    Here we report an ON–OFF effect on electrocatalytic amplification when the molecules are connected to each other on an electrode surface. When the molecular connection is achieved, the redox potential of the catalytic redox ...
  • Stereochemistry-Dependent Proton Conduction in Proton Exchange Membrane Fuel Cells 
    THIMMAPPA, RAVIKUMAR; DEVENDRACHARI, MRUTHYUNJAYACHARI CHATTANAHALLI; KOTTAICHAMY, ALAGAR RAJA; TIWARI, OMSHANKER; GAIKWAD, PRAMOD; Paswan, Bhuneshwar; THOTIYL, MUSTHAFA OTTAKAM (American Chemical Society, 2016-01)
    Graphene oxide (GO) is impermeable to H2 and O2 fuels while permitting H+ shuttling, making it a potential candidate for proton exchange membrane fuel cells (PEMFC), albeit with a large anisotropy in their proton transport ...
  • Polarity governed selective amplification of through plane proton shuttling in proton exchange membrane fuel cells 
    GAUTAM, MANU; DEVENDRACHARI, MRUTHYUNJAYACHARI CHATTANAHALLI; THIMMAPPA, RAVIKUMAR; KOTTAICHAMY, ALAGAR RAJA; SHAFI, SHAHID POTTACHOLA; GAIKWAD, PRAMOD; Kotresh, Harish Makri Nimbegondi; THOTIYL, MUSTHAFA OTTAKAM (Royal Society of Chemistry, 2017-02)
    Graphene oxide (GO) anisotropically conducts protons with directional dominance of in plane ionic transport (σ IP) over the through plane (σ TP). In a typical H2–O2 fuel cell, since the proton conduction occurs through the ...
  • Tuning the Interfacial Chemistry of Redox‐Active Polymer for Bifunctional Probing 
    Aralekallu, Shambhulinga; THIMMAPPA, RAVIKUMAR; GAIKWAD, PRAMOD; Chattanahalli Devendrachari, Mruthyunjayachari; KOTTAICHAMY, ALAGAR RAJA; SHAFI, SHAHID POTTACHOLA; Lokesh, Koodlur Sannegowda; Sanchez, Julio; THOTIYL, MUSTHAFA OTTAKAM (Wiley, 2017-03)
    Redox‐active conducting polymers are ubiquitous in sensing devices, owing to their good conductivity, ease of synthesis, and processability. The necessity of proton transfer during their redox energy modulations projected ...
  • Redox Active Binary Logic Gate Circuit for Homeland Security 
    GAIKWAD, PRAMOD; Kadlag, Kavita; Nambiar, Manasa; DEVENDRACHARI, MRUTHYUNJAYACHARI CHATTANAHALLI; Aralekallu, Shambhulinga; KOTTAICHAMY, ALAGAR RAJA; BHAT, ZAHID MANZOOR; THIMMAPPA, RAVIKUMAR; SHAFI, SHAHID POTTACHOLA; THOTIYL, MUSTHAFA OTTAKAM (American Chemical Society, 2017-07)
    Bipolar junction transistors are at the frontiers of modern electronics owing to their discrete voltage regulated operational levels. Here we report a redox active binary logic gate (RLG) which can store a “0” and “1” with ...
  • An Interface-Controlled Redox Switch for Wastewater Remediation 
    KHAIRE, SIDDHI; GAIKWAD, PRAMOD; Aralekallu, Shambhulinga; BHAT, ZAHID MANZOOR; KOTTAICHAMY, ALAGAR RAJA; DEVENDRACHARI, MRUTHYUNJAYACHARI CHATTANAHALLI; THIMMAPPA, RAVIKUMAR; SHAFI, SHAHID POTTACHOLA; GAUTAM, MANU; THOTIYL, MUSTHAFA OTTAKAM (Wiley, 2018-01)
    Bipolar junction transistors (BJTs) can function as electrically reversible switches; nevertheless, triggering such circuits requires a distinct voltage bias at the base terminal. Here, we show a proof‐of‐concept of an ...
