Potentiometric Studies on Ion-Transport Selectivity in Charged Gold Nanotubes

Nanomaterials
Under ideal conditions, nanotubes with a fixed negative tube-wall charge will reject anions and transport-only cations. Because many proposed nanofluidic devices are optimized in this ideally cation-permselective state, it is important to know the ...

Protolytic Reactions at Electrified TiO₂ P25 Interface: Quantitative and Thermodynamic Characterization

Molecules
Protolytic reactions on the surface of a titania photocatalyst (TiO2 P25 containing chlorine impurities) were studied using potentiometric and calorimetric acid-base titration. The impurity was removed by either washing or heat treatment.
