Bass guitarist and youtuber Charles Berthoud also makes extensive use of detuners, generally on a LeFay D-Tuner (which as the name hints was designed with a detuner on each string). Adrian Legg is a popular guitarist making use of rapid tuning changes. He was prominent in the late 1980s. The idea may have originated from the double bass extenders.
Detuner is a generic term for a jet engine test cell exhaust system muffler. Aircraft jet engine testing facilities typically require a means to vent and dampen the engine exhaust. The engine exhaust flow is "augmented" with a relatively large flow of cooling air induced by a Venturi effect into the exhaust silencing system, so the exhaust ...
Each instrument used in analytical chemistry has a useful working range. This is the range of concentration (or mass) that can be adequately determined by the instrument, where the instrument provides a useful signal that can be related to the concentration of the analyte. [1] All instruments have an upper and a lower working limit.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
In chemistry, absolute configuration refers to the spatial arrangement of atoms within a molecular entity (or group) that is chiral, and its resultant stereochemical description. [1] Absolute configuration is typically relevant in organic molecules where carbon is bonded to four different substituents .
Linear potential sweep. Voltammetry is a category of electroanalytical methods used in analytical chemistry and various industrial processes. In voltammetry, information about an analyte is obtained by measuring the current as the potential is varied.
The idea of a Langmuir–Blodgett (LB) film was first proven feasible in 1917 when Irving Langmuir (Langmuir, 1917) showed that single water-surface monolayers could be transferred to solid substrates. 18 years later, Katharine Blodgett made an important scientific advance when she discovered that several of these single monolayer films could be stacked on top of one another to make multilayer ...
The second speculation is the most likely the one since in the 1937 edition of Hackh's Chemical Dictionary "platinum policeman," defined as "a platinum-iridium claw that fits over a glass rod and is used to hold a quantitative filter during ignition," [2] which the purpose of the policeman was to prevent the escape of stray filter paper from ...
