A new insight into the oxidative mechanism of caffeine and related methylxanthines in aprotic medium: May caffeine be really considered as an antioxidant? [PDF]

, 2018
Background: Antioxidant properties have been recently suggested for caffeine that seems showing protective effects against damages caused by oxidative stress. In particular, a HO% scavenging activity has been ascribed to caffeine. Even if the oxidation

Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Electrochemical study of hydrochlorothiazide on electrochemically pre-treated pencil graphite electrode as a sensor

Sensing and Bio-Sensing Research, 2017
An electrochemical anodic behavior of hydrochlorothiazide (HCTZ) was studied by using electrochemically pretreated pencil graphite electrode (EPPGE) using cyclic voltammetry (CV), differential pulse voltammetry (DPV) and square wave voltammetry (SWV ...

Electrochemistry and Spectroelectrochemistry of 1,4-Dinitrobenzene in Acetonitrile and Room-Temperature Ionic Liquids: Ion-Pairing Effects in Mixed Solvents [PDF]

, 2014
Room-temperature ionic liquids (RTILs) have been shown to have a significant effect on the redox potentials of compounds such as 1,4-dinitrobenzene (DNB), which can be reduced in two one-electron steps.

Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

Advanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...

NiP/SiC composite coatings: the effects of particles on the electrochemical behaviour [PDF]

, 2005
NiP/SiC (17 at.% P) composite coatings were prepared by electrodeposition from a Brenner type plating bath containing SiC particles. Cyclic voltammetry and immersion time were used to evaluate the electrochemical behaviour of these coatings.

Cyclic Voltammetry Studies on Substituted Arenesulfonhydrazides [PDF]

Journal of Chemical Research, 2000
Additional Z and Boc groups on the vicinal nitrogen of sulfonyl hydrazines have no significant effect on the cathodic potential of the sulfonyl functions as measured by cyclic voltammetry, whereas a Boc group on the geminal nitrogen invariably gives rise to shifts of about 0.2 V to less negative potential similar to those previously observed for ...

Interfacial and Crystallographic Regulation of Zinc Anode via Electric Double Layer Reconstruction for Highly Stable Zn Anode

Advanced Functional Materials, EarlyView.
Trace amounts of perfluoro‐1‐butanesulfonyl fluoride enables the regulation of the Zn/electrolyte interface by the generated zincophilic ─SO3H groups with long hydrophobic ─CF2 tails, which adsorb strongly onto the Zn surface, displace water molecules from the inner Helmholtz plane, and reconstruct the electrical double‐layer structure.

Original Conductive Nano-Co3O4 Investigated as Electrode Material for Hybrid Supercapacitors [PDF]

, 2011
Cobalt oxides have been extensively used as conductive additives for Ni-MH batteries. We report in this paper the performances of an original nanometric cobalt oxide, close to Co3O4, as electrode material for hybrid supercapacitors.
