Galinstan is a new kind of electrode material and the galinstan electrode is a promising alternative to the commonly used mercury electrodes. The eutectic mixture of gallium, indium and tin is liquid at room temperature (m.p. −19°C) and its voltammetric behaviour is similar to that of mercury. The potential windows of use were determined for different pH values and are similar to those obtained with conventional mercury electrodes. Furthermore, the high hydrogen overpotential, which is… 
Anodic Stripping Voltammetry with Galinstan as Working Electrode
The liquid alloy galinstan is used to determine low concentrations in microgram per liter level of trace metals like copper, cadmium, lead, bismuth, antimony and thallium using anodic stripping
Electrochemical Properties and Range of Application of Mixed Gold Bismuth Electrodes
Electrochemical properties for mixed gold-bismuth electrodes have been evaluated. Increased overpotential towards the hydrogen evolution reaction (HER) was found as a function of increased bismuth
Application of a nanoporous gold electrode for the sensitive detection of copper via mercury-free anodic stripping voltammetry.
The MPS-modified NPG (MPS@NPG) electrode not only significantly enhanced the sensitivity in detecting Cu(2+) but also effectively prevented electrode surface fouling from surfactant adsorption.
Preparation of Metal Amalgam Electrodes and Their Selective Electrocatalytic CO2 Reduction for Formate Production
Electrochemical CO2 reduction to produce formate ions has studied for the sustainable carbon cycle. Mercury in the liquid state is known to be an active metallic component to selectively convert CO2

It follows from critical evaluation of possibilities and limitations of modern voltammetric/amperometric methods that one of the biggest obstacles in their practical applications in real sample
Note: electrode polarization of Galinstan electrodes for liquid impedance spectroscopy.
Electrode polarization is a significant obstacle in the impedance measurements of ionic liquids. An atomically smooth electrode surface could potentially reduce unwanted impedance contributions from


Pyrolytic carbon film electrodes
Home-made pyrolytic carbon film electrodes (PCFE) were tested in voltammetric experiments. Different drugs were analyzed by differential pulse voltammetry. In many cases the reproducibility of the
Scanning tunneling microscopic and voltammetric studies of the surface structures of an electrochemically activated glassy carbon electrode.
The microscopic surface structures of electrochemically activated glassy carbon have been examined by scanning tunneling microscopy and, on the basis of the STM voltammetric results, the microscopic structure of the activated electrode is proposed.
Scanning electrochemical microscopy: Investigation of hydrogen oxidation at polycrystalline noble metal electrodes
Scanning electrochemical microscopy (SECM) was used to study the kinetics of hydrogen oxidation on platinum, iridium, and rhodium substrates in acidic media. Hydrogen was generated at a platinum tip
Pyrolytic carbon film electrodes
SummaryThe preparation is described of pyrolytic carbon film electrodes (PCFE) with outstanding properties. The physical and chemical resistance is remarkable as is the low residual current in
Electroinjection of colloid particles and biopolymers into single unilamellar liposomes and cells for bioanalytical applications.
A combined electroporation and pressure-driven microinjection method for efficient loading of biopolymers and colloidal particles into single-cell-sized unilamellar liposomes was developed and initiation of a chemical intercalation reaction between T2-phage DNA and YOYO-1 is demonstrated by dual injection into a single giant unilamese liposome.
A galinstan expansion femtosyringe for microinjection of eukaryotic organelles and prokaryotes
Injection of a plasmid containing the bla gene into the cyanobacterium Phormidium laminosum resulted in transformed ampicillin-resistant cultures and green fluorescent protein was expressed in attached leaves of tobacco and Vicia faba following injection of DNA cantaining its gene into individual chloroplasts.
