  2. List of metal detecting finds - Wikipedia

    en.wikipedia.org/wiki/List_of_metal_detecting_finds

    This is a list of historically significant items found by metal detecting method, only excluding magnet fishing finds, since magnet fishing is usually considered a distinctively different and separate hobby from traditional metal detecting.

  3. 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.

  4. 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 ...

  5. 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.

  6. SN1 reaction - Wikipedia

    en.wikipedia.org/wiki/SN1_reaction

    In this regime, the first step (ionization of the alkyl bromide) is slow, rate-determining, and irreversible, while the second step (nucleophilic addition) is fast and kinetically invisible. However, under certain conditions, non-first-order reaction kinetics can be observed.

  7. SN2 reaction - Wikipedia

    en.wikipedia.org/wiki/SN2_reaction

    Competition experiment between SN2 and E2. With ethyl bromide, the reaction product is predominantly the substitution product. As steric hindrance around the electrophilic center increases, as with isobutyl bromide, substitution is disfavored and elimination is the predominant reaction. Other factors favoring elimination are the strength of the ...
