2. Metal detector - Wikipedia

   en.wikipedia.org/wiki/Metal_detector

   U.S. Army soldiers use a military standard metal detector. A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped ...

3. Digital sensor - Wikipedia

   en.wikipedia.org/wiki/Digital_sensor

   A digital sensor system consists of the sensor itself, a cable, and a transmitter. The differences with analog sensor systems are: a) The sensor has an electronic chip. The measuring signal is directly converted into a digital signal inside the sensor. The data transmission through the cable is also digital.

4. 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 ...

5. Induction loop - Wikipedia

   en.wikipedia.org/wiki/Induction_loop

   An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence ...

7. 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 ...
