2. 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.

3. Everhart–Thornley detector - Wikipedia

   en.wikipedia.org/wiki/Everhart–Thornley_detector

   The E-T secondary electron detector can be used in the SEM's back-scattered electron mode by either turning off the Faraday cage or by applying a negative voltage to the Faraday cage. However, better back-scattered electron images come from dedicated BSE detectors rather than from using the E–T detector as a BSE detector.

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. 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 ...

6. 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.

7. Metal testing - Wikipedia

   en.wikipedia.org/wiki/Metal_Testing

   Metal testing is a process or procedure used to check composition of an unknown metallic substance. [1] There are destructive processes and nondestructive processes. Metal testing can also include, determining the properties of newly forged metal alloys .

8. Growler (electrical device) - Wikipedia

   en.wikipedia.org/wiki/Growler_(electrical_device)

   The alternating magnetic flux set up by the growler passes through the windings of the armature coil, generating an alternating voltage in the coil. A short in the coil creates a closed circuit that will act like the secondary coil of a transformer, with the growler acting like the primary coil.

9. Solvent effects - Wikipedia

   en.wikipedia.org/wiki/Solvent_effects

   In chemistry, solvent effects are the influence of a solvent on chemical reactivity or molecular associations. Solvents can have an effect on solubility, stability and reaction rates and choosing the appropriate solvent allows for thermodynamic and kinetic control over a chemical reaction.
