  2. Nucleophilic aromatic substitution - Wikipedia

    en.wikipedia.org/wiki/Nucleophilic_aromatic...

    By the same coin, the loss of the chloride or hydroxide is fast, because the ring regains aromaticity. Recent work indicates that, sometimes, the Meisenheimer complex is not always a true intermediate but may be the transition state of a 'frontside S N 2' process, particularly if stabilization by electron-withdrawing groups is not very strong. [2]

  3. Associative substitution - Wikipedia

    en.wikipedia.org/wiki/Associative_substitution

    The terminology is typically applied to organometallic and coordination complexes, but resembles the Sn2 mechanism in organic chemistry. The opposite pathway is dissociative substitution, being analogous to the Sn1 pathway. Intermediate pathways exist between the pure associative and pure dissociative pathways, these are called interchange ...

  4. Compact Muon Solenoid - Wikipedia

    en.wikipedia.org/wiki/Compact_Muon_Solenoid

    This means it produces light in proportion to the particle's energy. These high-density crystals produce light in fast, short, well-defined photon bursts that allow for a precise, fast and fairly compact detector. It has a radiation length of χ 0 = 0.89 cm, and has a rapid light yield, with 80% of light yield within one crossing time (25 ns ...

    en.wikipedia.org/wiki/Low-background_steel

    Low-background steel, also known as pre-war steel [1] and pre-atomic steel, [2] is any steel produced prior to the detonation of the first nuclear bombs in the 1940s and 1950s. Typically sourced from ships (either as part of regular scrapping or shipwrecks ) and other steel artifacts of this era, it is often used for modern particle detectors ...

  7. Eddy-current testing - Wikipedia

    en.wikipedia.org/wiki/Eddy-current_testing

    In this technique, permeability variations are suppressed by applying a magnetic field. The saturation probes contain conventional eddy current coils and magnets. This inspection is used on partially ferromagnetic materials such as nickel alloys, duplex alloys, and thin-ferromagnetic materials such as ferritic chromium molybdenum stainless steel.
