Amperometric titration

Amperometric titration refers to a class of titrations in which the equivalence point is determined through measurement of the electric current produced by the titration reaction. It is a form of quantitative analysis.

Salicylaldoxime

Salicylaldoxime is an organic compound described by the formula C6H4CH=NOH-2-OH. It is the oxime of salicylaldehyde. This crystalline, colorless solid is a chelator and sometimes used in the analysis of samples containing transition metal ions, with which

Total ionic strength adjustment buffer

Total ionic strength adjustment buffer (TISAB) is a buffer solution which increases the ionic strength of a solution to a relatively high level. This is important for potentiometric measurements, including ion selective electrodes, because they measure

Optical axis grating

Optical axis gratings (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are

Quantum electrochemistry

The scientific school of Quantum electrochemistry began to form in the 1960s under Revaz Dogonadze. Generally speaking, the field comprises the notions arising in electrodynamics, quantum mechanics, and electrochemistry; and so is studied by a very large

Fleaker

A Fleaker is a brand of container for liquids used in the laboratory. It can be described as a cross between the Griffin beaker and the Erlenmeyer flask

Jamin interferometer

The Jamin interferometer is a type of interferometer, related to the Mach–Zehnder interferometer. It was developed in 1856 by the French physicist Jules Jamin

Ion trap

An ion trap is a combination of electric or magnetic fields used to capture charged particles — known as ions — often in a system isolated from an external environment. Ion traps have a number of scientific uses such as mass spectrometry, basic

Sub-sampling (chemistry)

In analytical chemistry, sub-sampling is a procedure by which a small, representative sample is taken from a larger sample. Good sub-sampling technique becomes important when the large sample is not homogeneous

Elution

In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions

Azatbek Omurbekov

Azatbek Asanbekovich Omurbekov is a Russian colonel, who reportedly heads the 64th Separate Motor Rifle Brigade, a unit suspected of committing war crimes in the Ukrainian town of Bucha. He has been dubbed by media outlets "the butcher of Bucha". In
