In Situ Transmission Electron Microscopy of the Electrochemical Intercalation of Graphite in Concentrated Sulfuric Acid

Graphite intercalation compounds, where some atom or molecule is inserted between the carbon layers of the host graphite, are attractive materials for charge storage. In commercial, rechargeable lithium ion batteries, for instance, the graphite anode intercalates and de-intercalates lithium as the battery is cycled [1]. In this work we present our in situ scanning transmission electron microsco...

Electrochemical Oxidation of Single Wall Carbon Nanotube Bundles in Sulfuric Acid

Electrochemical doping of bisulfate ions into single wall carbon nanotube (SWNT) bundles has been studied using coulometry, cyclic voltammetry, mass-uptake measurements, and Raman scattering experiments. A spontaneous charge-transfer reaction is observed prior to the application of an electrochemical driving force, in sharp contrast to previous observations in the graphite-H2SO4 system. A mass ...

ELECTROCHEMICAL BEHAVIOUR OF AISI 304 STAINLESS STEEL IN SULFURIC SOLUTION: EFFECTS OF ACID CONCENTRATION

The effects of H2SO4 concentration on the electrochemical behaviour of passive films formed on AISI 304 stainless steel were investigated using by potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Potentiodynamic polarization indicated that the corrosion potentials were found to shift towards negative direction with an increase in solution co...

Ordering of poly(3-hexylthiophene) in solution and on substrates induced by concentrated sulfuric acid.

The ordering of poly(3-hexylthiophene) (P3HT) molecules in dilute P3HT/chloroform solutions was accelerated by adding small amounts of concentrated H2SO4. The concentrated H2SO4 stimulates the nucleation of crystals, which controls the overall rate of P3HT crystallization. Dispersed nuclei spur P3HT solution crystallization, and adsorbed nuclei induce P3HT crystallization on substrates. By AFM,...
