During this process, ccNiR draws electrons from the quinol pool, which are ultimately provided by a dehydrogenase such as formate dehydrogenase or hydrogenase.

When the input current is flowing, the base electrode has a relative positive charge, so it draws electrons toward it from the emitter.

This reduction ultimately draws electrons from water, yielding molecular oxygen as a final oxidation product.

A strong positive voltage applied to the gate draws excess mobile electrons (which are negatively charged) into a layer between the insulator and the semiconductor.

The standard electrode potential is the tendency of a bulk material to draw free electrons to itself.

With the transistor, the researchers were able to apply an electric field that could draw electrons away from the buckyballs or drive additional electrons onto them.

The carbonyl group draws electrons away from the alkene, and the alkene group is, therefore, deactivated towards an electrophile, such as bromine or hydrochloric acid.

In this case the higher electronegativity of the Cl draws electrons toward this atom and the substituent has an asymmetric distribution of electron density.

In the typical setup, the tungsten filament is the cathode and a positively biased anode draws electrons from the tip of the tungsten filament.

An electron withdrawing group or EWG draws electrons away from a reaction center.
