cross coupling
11cross talk — 1. interference heard on a telephone or radio because of unintentional coupling to another communication channel. 2. incidental conversation; chatter, as opposed to formal discussion: The meeting was slowed by cross talk between board members. 3 …
12cross talk — noun Date: 1887 1. unwanted signals in a communication channel (as in a telephone, radio, or computer) caused by transference of energy from another circuit (as by leakage or coupling) 2. a. conversation that does not relate to th …
13Negishi coupling — The Negishi coupling is a cross coupling reaction in organic chemistry involving an organozinc compound, an organic halide and a nickel or palladium catalyst creating a new carbon carbon covalent bond:[1][2] The halide X can be chloride, bromine… …
14Kumada coupling — A Kumada coupling or Kumada Corriu coupling is a cross coupling reaction in organic chemistry between a alkyl or aryl Grignard reagent and an aryl or vinyl halocarbon catalysed by nickel or palladium. This reaction is relevant to organic… …
15Hiyama coupling — In organic chemistry, a Hiyama coupling is a palladium or nickel catalyzed cross coupling reaction of organosilanes with organic halides or triflates. Hiyama couplings were first reported by Yasuo Hatanaka and Tamejiro Hiyama in 1988 [ Cross… …
16Pinacol coupling reaction — A pinacol coupling reaction is an organic reaction in which a carbon carbon covalent bond is formed between the carbonyl groups of an aldehyde or a ketone in presence of an electron donor in a free radical process Ref|1. The reaction product is a …
17Castro-Stephens coupling — The Castro Stephens Coupling is a cross coupling reaction between a Copper(I) acetylide and an aryl halide forming a disubstituted alkyne and a copper(I) halide. :The reaction was discovered in 1963 by chemists Casto and Stephens [ The… …
18Excitation-contraction coupling — Excitation contraction (EC) coupling is a term coined in 1952 to describe the physiological process of converting an electrical stimulus to a mechanical response [1]. This process is fundamental to muscle physiology, whereby the electrical… …
19Gear coupling — A gear coupling is a mechanical device for transmitting torque between two shafts that are not coaxial. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle. Each joint consists of …
20Substrate coupling — In an integrated circuit, a signal can couple from one node to another via the substrate. This phenomenon is referred to as substrate coupling or substrate noise coupling.The push for reduced cost, more compact circuit boards, and added customer… …
