  2. Raman spectroelectrochemistry - Wikipedia

    en.wikipedia.org/wiki/Raman_spectroelectrochemistry

    Silica and alumina coating can improve the chemical and thermal stability of nanoparticles. This fact has great importance in the in-situ study of catalytic reactions. The high sensitivity of the SHINERS surfaces makes these nanostructures a promising tool for the study of liquid-solid interfaces, especially in spectroelectrochemistry. [3] [12 ...

    en.wikipedia.org/wiki/Spectroelectrochemistry

    Spectroscopic and electrochemical techniques that form the spectroelectrochemistry. Spectroelectrochemistry (SEC) is a set of multi-response analytical techniques in which complementary chemical information (electrochemical and spectroscopic) is obtained in a single experiment.

    en.wikipedia.org/wiki/Electrochemistry

    English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change.

  6. Randles–Sevcik equation - Wikipedia

    en.wikipedia.org/wiki/Randles–Sevcik_equation

    In electrochemistry, the Randles–ŠevĨík equation describes the effect of scan rate on the peak current (i p) for a cyclic voltammetry experiment. For simple redox events where the reaction is electrochemically reversible, and the products and reactants are both soluble, such as the ferrocene/ferrocenium couple, i p depends not only on the concentration and diffusional properties of the ...

    en.wikipedia.org/wiki/Quartz_crystal_microbalance

    Quartz is one member of a family of crystals that experience the piezoelectric effect.The piezoelectric effect has found applications in high power sources, sensors, actuators, frequency standards, motors, etc., and the relationship between applied voltage and mechanical deformation is well known; this allows probing an acoustic resonance by electrical means.

  8. Marcus theory - Wikipedia

    en.wikipedia.org/wiki/Marcus_theory

    In theoretical chemistry, Marcus theory is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called the electron acceptor). [1]

  9. Electrochemical kinetics - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_kinetics

    Electrochemical kinetics is the field of electrochemistry that studies the rate of electrochemical processes. This includes the study of how process conditions, such as concentration and electric potential, influence the rate of oxidation and reduction reactions that occur at the surface of an electrode, as well as an investigation into electrochemical reaction mechanisms.
