Differential pulse voltammetry (DPV) of TOPO-capped CdTe nanoparticles (NPs) in dichloromethane and a mixture of benzene and acetonitrile showed two anodic and one cathodic peaks of the NPs themselves and an additional anodic peak resulting from the oxidation of reduced NPs. The electrochemical band gap (∼2.1 eV) between the first anodic and cathodic DPV peaks was close to the value (2 eV) obta...

Electrochemical current and potential transients were measured during anodic oxidation of aluminum, on time scales of 0.1–100 ms after anodizing began. Aluminum foil samples were prepared by surface treatments yielding oxide films of thickness 5 nm or smaller. A mathematical model was developed for the transients based on steady-state and transient conduction phenomena established for much thic...
