Electrochemistry is promising to study interfacial electron transfers and redox reactions, but its lack of access molecular structural information limits understanding on complicated systems. Complementary optical spectroscopic measurements in situ become necessary visualize the electrochemical processes, providing electronic identification reactants products. Recent advancement instrumentation...

Noble metal nanoparticles with plasmon resonance features have been widely applied in electrocatalysis and photo-electrochemistry owing to their unique physical, optical, catalytic properties. As heterogeneity of nanostructures has considerable influence on activities, investigation electrochemical process a single nano-catalyst is necessary eliminate bulk effect averaged results. Dark-field mi...

The thermodynamics of ferric and ferrous haem affinity of a de novo designed four-alpha-helix bundle protein and the associated haem electrochemistry is described.

Nanoimpact electrochemistry (NIE) is a straightforward analytical technique to study at high throughput the reactivity of single nanoparticles (NPs) colliding with biased ultramicroelectrode (UME). As NIE can reveal both NP size and catalytic activity, this strategy be employed establish relationships between these two descriptors. Herein, it shown that electrode material crucial for visualizin...

Abstract UV/Vis absorption spectroelectrochemistry is a very promising analytical technique due to the complementary information that simultaneously obtained from electrochemistry and spectroscopy. In this work, used in parallel configuration study oxidation of folic acid alkaline medium. Herein, has been detect both products consumed at electrode/solution interface, allowing us develop an prot...

Electrochemiluminescence (ECL) is a light-emitting phenomenon triggered by electrochemistry. The resulting optical signal enables spatiotemporal resolution of the luminescent that can be imaged with high accuracy. field ECL evolving rapidly from an analytical method widely applied in biosensing to novel microscopy technique. efficient generation depends on electrode materials, luminophore/corea...

Simultaneously, the p-synephrine 1 template was imprinted, and a ferrocene redox probe covalently immobilized in (bis-bithiophene)-based polymer, resulting molecularly imprinted polymer (MIP) deposited on Pt electrode as thin film to form self-reporting MIP film-based chemosensor. After subsequent extraction from film, analyte determined with differential pulse voltammetry (DPV) (redox probe)-f...

Electrochemistry and adlayer structure of trinitrotoluene (TNT) on an Au(111) electrode were investigated using cyclic voltammetry and in situ electrochemical scanning tunneling microscopy (ECSTM).

Four rhenium(I) chromophores attached to a dirhodium(n) core form a new hexametallic light-harvesting assembly as characterised by X-ray crystallography, UV-vis spectroscopy and electrochemistry.
