This paper proposes a high reaction area (HRA) electrode with finely dispersed electrocatalysts supported on carbon nanotubes (CNTs) for high performance micro direct methanol fuel cell (μDMFC). Ionomer Nafion® loading by spin-coating on the catalysts was in-detail investigated for performance enhancement in anodic half-cell. In terms of electrochemical surface area (ESA) and charge transfer resistance...
In this work, carbon nanotube (CNT) in anodized alumina templates electrode is developed as a new electrochemical electrode for chemical sensing application. Its electrochemical sensing performance is evaluated for salbutamol detection with different concentrations ranging from 10-6 to 10-4 mol.l-1. CV curves show irreversible oxidation peak at ~0.6 V. The amperometric response is linear with a sensitivity...
Carbon nanotube (CNT) based bioconjugates are among the candidates for molecular level electronics. In this work, we have studied transport mechanism of single walled carbon nanotube (SWNT) - peptide nucleic acid (PNA) bioconjugates. Electrical conductivity of the bioconjugates was studied at temperatures ranging from 70 K to 350 K. Negative differential resistance (NDR) behavior was observed at almost...
