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 ...
Electrochemistry, which studies the interaction between electrical energy and chemical changes. This technique allows us to analyse reactions that involve electron transfer processes ( redox reactions).
The Handbook of Electrochemistry, edited by Cynthia Zoski, is a sourcebook containing a wide range of electrochemical information.It provides details of experimental considerations, typical calculations, and illustrates many of the possibilities open to electrochemical experimentators.
Electrochemistry also has important applications in the food industry, like the assessment of food/package interactions, [36] the analysis of milk composition, [37] the characterization and the determination of the freezing end-point of ice-cream mixes, or the determination of free acidity in olive oil.
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.
The electrochemical mechanisms of electrocatalytic processes are a common research subject for various fields of chemistry and associated sciences. This is important to the development of water oxidation and fuel cells catalysts. For example, half the water oxidation reaction is the reduction of protons to hydrogen, the subsequent half reaction.

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.
