Rapid Characterization

Oak alternatives (OAs) such as chips, granulates or staves, are becoming increasingly used in the wine industry. Although they are mostly considered for their contribution to wine aroma, they are also a source of phenolic compounds to be released in the wine, in particular ellagitannins contributing to wine mouthfeel and antioxidant characteristics. In the present study, we explore the potential for a rapid analytical method based on linear sweep voltammetry (LSV) combined with disposable sensors to provide a rapid measure of the oxidizable compounds present in different OAs, as well as their characterization. Strong correlations were found between the tannin content of different OAs and the total current measures during LSV analysis, allowing a rapid quantification of the oxidizable compounds present, mostly ellagitannin. Application of derivatization to raw voltammograms allowed extraction of a number of features that can be used for classification purposes, in particular with respect to OAs types (chips or staves) and degree of toasting.

AC photoelectrochemical imaging at electrolyte–semiconductor interfaces provides spatially resolved information such as surface potentials, ion concentrations and electrical impedance. In this work, thin films of InGaN/GaN were used successfully for AC photoelectrochemical imaging, and experimentally shown to generate a considerable photocurrent under illumination with a 405 nm modulated diode laser at comparatively high frequencies and low applied DC potentials, making this a promising substrate for bioimaging applications. Linear sweep voltammetry showed negligible dark currents. The imaging capabilities of the sensor substrate were demonstrated with a model system and showed a lateral resolution of 7 microns.

The novel Ti/PbO2 electrodes have been prepared by electrodeposition and anodization. The electrodes were characterized by SEM, XRD and linear sweep voltammetry (LSV). The SEM and XRD analysis reveal that Sn in the Pb-Sn alloy changes the β-PbO2/α-PbO2 ratio and the structure of the PbO2 layer. Sn content in Pb-Sn alloy is beneficial for the formation of β-PbO2. LSV analysis shows that the novel Ti/PbO2 electrodes have high oxygen evolution potential, which can reach 1.75V.

Electrodeposition of CuInSe2 (CIS) thin films has been investigated by linear sweep voltammetry on F-doped tin oxide (FTO) glass in electrolytes containing citric acid. It is found that one-step electrodeposited CIS thin films have great deviation from the ideal stoichiometric ratio. After deposited a film at -900 mV (vs.SCE) for 20s on the FTO, the linear sweep voltammetry has showed that only one reduction current peak at -550 mV is remained, and the two-step electrodeposited CIS film showed a near- toichiometric ratio of 1:0.9:2.1.
