Analysis of bio-anode performance through electrochemical impedance spectroscopy
Elsevier (2015-12)In this paper we studied the performance of bioanodes under different experimental conditions using polarization curves and impedance spectroscopy. We have identified that the large capacitances of up to 1 mF·cm− 2 for ... -
Competitive Photoelectrochemical Methanol and Water Oxidation with Hematite Electrodes
ACS Publications (2015-03-24)Photocatalytic water and methanol oxidation were studied at thin film hematite electrodes synthesized by atomic layer deposition (ALD). Systematic photoelectrochemical characterization along with O2 evolution measurements ... -
Facile kinetics of Li-ion intake causes superior rate capability in multiwalled carbon nanotube@TiO2 nanocomposite battery anodes
Elsevier (2014-12)Nanotechnology produces hybrids with superior properties than its individual constituents. Here MWCNT@TiO2 composites have been synthesized by controlled hydrolysis of titanium isopropoxide over MWCNT, to be incorporated ... -
Germanium coating boosts lithium uptake in Si nanotube battery anodes
Royal Society of Chemistry (2014)Si nanotubes for reversible alloying reaction with lithium are able to accommodate large volume changes and offer improved cycle retention and reliable response when incorporated into battery anodes. However, Si nanotubes ... -
Influence of the anion on diffusivity and mobility of ionic liquids composite polybenzimidazol membranes
Elsevier (2020-07-04)The study of proton conductivity processes has received increasing attention in the past decades due to their potential applications in fields such as electrochemical devices and fuel cells. Despite the high number of ... -
Influence of the Potassium Chloride Concentration on the Physical Properties of Electrodeposited ZnO Nanowire Arrays
American Chemical Society (2008)The structural, electrical, and optical properties of zinc oxide nanowire arrays electrodeposited from the reduction of molecular oxygen in aqueous solutions containing zinc chloride and potassium chloride are studied as ... -
Quantification of charge carriers and acetate diffusion lengths in intermittent electro-active biofilms using Electrochemical Impedance Spectroscopy
Elsevier B.V. (2023-12-30)Intermittent anode potential regimes have been used to increase the concentration of charge carriers in electro-active biofilms (EABfs). Even though this increased number of carriers is typically correlated to higher current ... -
Understanding the Role of Underlayers and Overlayers in Thin Film Hematite Photoanodes
Wiley (2014-12-23)Recent research on photoanodes for photoelectrochemical water splitting has introduced the concept of under- and overlayers for the activation of ultrathin hematite films. Their effects on the photocatalytic behavior were ...
