Cover Feature: Electrochemical Characterization of Fe(II) Complexation Reactions at an Electrified Micro Liquid‐Liquid Interface (ChemElectroChem 9/2021)

Tuning ion correlations at an electrified soft interface.

Ion distributions play a central role in various settings-from biology, where they mediate the electrostatic interactions between charged biomolecules in solution, to energy storage devices, where they influence the charging properties of supercapacitors. These distributions are determined by interactions dictated by the chemical properties of the ions and their environment as well as the long-...

Scanning Electrochemical Microscopy. 31. Application of SECM to the Study of Charge Transfer Processes at the LiquidLiquid Interface

The kinetics of the electron transfer and ion transfer at the interface between two immiscible electrolyte solutions (ITIES) were probed directly by scanning electrochemical microscopy (SECM). The liquid/liquid (Le., waterhitrobenzene) interface appeared to be sharp and wave-free on the submicrometer scale. The use of SECM allowed the electron transfer between ferrocene species in nitrobenzene ...

First-Principles Calculations of the Electrochemical Reactions of Water at an Immersed Ni„111.../H2O Interface

Electrochemical processes occurring in aqueous solutions are critically dependent upon the interaction between the metal electrode and the solvent. In this work, density functional theory is used to calculate the potentials for which molecular water and its activation products adsorbed hydrogen and hydroxide are stable when in contact with an immersed Ni 111 electrode. The adsorption geometries...

Fabrication of an Electrochemical Immunosensor for Determination of Human Chorionic Gonadotropin Based on PtNPs/Cysteamine/AgNPs as an Efficient Interface

An ultrasensitive electrochemical immunosensor for the detection of tumor marker human chorionic gonadotropin (hCG) was developed with a limit of detection as low as 2 pg mL-1 in phosphate buffer. The Platinum nanoparticles (PtNPs) were electrodeposited to modify the gold surface and to increase enlarging the electrochemically active sites, resulting in the facilitation of electron exchange. Cy...
