The sample is held at a large negative potential (1-10 kV) relative to the fluorescent screen.

It is believed to be one source of a slowly increasing negative potential that precedes movement onset.

All missing elements in this table are either not metals or have a negative standard potential.

Therefore many authors attempted to create a negative potential (tension) on the water flow.

The electrons act as a virtual cathode (negative electric potential).

The driving force here is the negative intracellular potential.

Climate change may have negative potential for woodland caribou as well.

The blocking effect is most effective when the K ions flow inward thus at a negative potential.

Field electron emission, which tends to reduce the negative potential, can be important due to the small size of the particles.

In certain adverbial frames, the optative indicates positive or negative potential.
