Electrochemical oxidative coupling

Electrochemical oxidative coupling is a synthetic method that joins two organic substrates by anodic oxidation at an electrode, replacing stoichiometric chemical oxidants with electricity and releasing hydrogen at the cathode.

Electrochemical pH-swing CO2 capture with quinone electrodes

Electrochemical pH-swing CO2 capture with quinone electrodes is a carbon-capture method where electrochemically reduced and oxidized quinones shift the pH of a solution, absorbing CO2 at high pH and releasing it at low pH.

Electrochemical polymerization

Electrochemical polymerization, also called electropolymerization, is a synthesis method in which an electrode's applied potential grows polymer films, chiefly conducting polymers such as polypyrrole and PEDOT.

Electrochemical potential

The electrochemical potential is the partial molar Gibbs energy of a substance at a specified electric potential, combining chemical and electrical contributions and underlying the Nernst equation.

Electrochemical quartz crystal microbalance

The electrochemical quartz crystal microbalance (EQCM) combines a quartz crystal microbalance with an electrochemical cell to measure mass changes at an electrode surface while current and potential are recorded.

Electrochemical random-access memory

Electrochemical random-access memory (ECRAM), also called a redox transistor, is a three-terminal non-volatile memory that stores analog conductance states via ion insertion, used as synapses in analog AI accelerators.

Electrochemical reduction of carbon dioxide

Electrochemical reduction of carbon dioxide, or carbon dioxide electrolysis, is an electrolysis process that converts CO2 into products such as carbon monoxide, formic acid, and ethylene.

Electrochemical reduction of carbon dioxide to carbon monoxide

Electrochemical reduction of carbon dioxide to carbon monoxide, or CO2-to-CO electrolysis, uses electrocatalysts at a cathode to convert CO2 into carbon monoxide, a key chemical-industry feedstock.

Electrochemical reduction of carbon dioxide to ethylene

The electrochemical reduction of carbon dioxide to ethylene is an electrosynthesis process that reduces CO₂ at copper cathodes to ethylene, pursued as a lower-carbon alternative to petroleum-based production.

Electrochemical reduction of carbon dioxide to methanol

Electrochemical reduction of carbon dioxide to methanol is an electrolysis process converting CO2 to methanol at a cathode, requiring a demanding six-electron reduction and copper-based catalysts.

Electrochemical reductive amination

Electrochemical reductive amination is a synthetic method that uses electricity at a cathode, rather than chemical reagents, to convert carbonyl compounds and amines into amines.

Electrochemical Scanning Microscopy

Electrochemical scanning microscopy (SECM, SECCM) comprises scanning probe techniques using micro/nanoelectrode or pipette-droplet probes to map local electrochemical activity, topography, and kinetics on electrocatalysts, batteries, and living cells.

Electrochemical scanning tunneling microscopy

Electrochemical scanning tunneling microscopy (EC-STM) is a form of scanning tunneling microscopy in which an immersed tunneling junction images electrode surfaces at atomic resolution under potential control, first reported in 1986.

Electrochemical surface-enhanced Raman spectroscopy

Electrochemical surface-enhanced Raman spectroscopy (EC-SERS) is a spectroelectrochemical technique that records greatly enhanced Raman spectra at electrified nanostructured electrodes, first reported in 1974 with pyridine on roughened silver.

Electrochemical synthesis

Electrochemical synthesis, also known as electrosynthesis, drives oxidation and reduction reactions by supplying electrons directly at electrodes, replacing stoichiometric redox reagents with cheap electric current, and spans organic synthesis and ammonia formation.

Electrochemical synthesis of hydrogen peroxide

Electrochemical synthesis of hydrogen peroxide is the production of H₂O₂ from water, oxygen, and electricity in an electrolytic cell, studied as a decentralized alternative to the dominant anthraquinone process.

Electrochemical synthesis of urea

Electrochemical synthesis of urea is the production of urea by electrocatalytic coupling of carbon dioxide with a nitrogen source such as nitrate under ambient conditions.

Electrochemical upcycling of glycerol is the conversion of glycerol, especially the crude glycerol coproduced with biodiesel, into higher-value chemicals like formic acid and dihydroxyacetone by electrocatalytic oxidation at an electrode under mild conditions.

Electrochemical upcycling of plastic waste

Electrochemical upcycling of plastic waste is a family of processes that use electrode reactions to convert waste polymers, especially PET, into higher-value chemicals, fuels, and monomers under mild conditions, a field growing rapidly since around 2021.

Electrochemiluminescence

Electrochemiluminescence, also called electrogenerated chemiluminescence or ECL, is light emission produced when electrochemically generated reactive intermediates form excited states, a technique offering high sensitivity and the basis of billions of clinical immunoassays run yearly.

Electrochemiluminescence assay

An electrochemiluminescence (ECL) assay is a bioanalytical method that quantifies biomolecules by generating light through electrochemical reactions at an electrode, most commonly in sandwich immunoassays using a ruthenium label.

Electrochemiluminescence detection

Electrochemiluminescence detection is an analytical technique in which electrochemical reactions excite species that emit light, allowing analytes near an electrode to be quantified from photon intensity.

Electrochemiluminescence imaging

Electrochemiluminescence imaging is an analytical method that records light from electrochemical reactions at an electrode with a camera, mapping target molecules across the surface with near-zero optical background.

Electrochemistry

Electrochemistry is the branch of chemistry that studies chemical processes involving electron transfer, especially reactions at the interface between an electrode and an electrolyte, converting chemical energy to electrical energy and back.

Electrochemotherapy

Electrochemotherapy is a local cancer treatment that combines high-voltage electric pulses with bleomycin or cisplatin, used mainly for cutaneous tumor nodules, achieving response rates near 80%.

Electrochromatography

Electrochromatography is a separation technique in which an electric field drives the mobile phase and analytes through a chromatographic stationary phase, so each compound's migration time reflects both electrophoretic mobility and chromatographic retention.

Electrochromism

Electrochromism is the reversible change of a material's color or optical properties when a voltage or current is applied, underlying smart windows, dimming mirrors, and displays.

Electroclash

Electroclash is an electronic dance music subgenre of the late 1990s and early 2000s, also called new electro or electro punk, blending synthpop, electro, and techno with punk attitude; popularized by Larry Tee's 2001 New York Electroclash Festival, with acts like Fischerspooner and Peaches, and revived in the 2020s.
