1. The electrical potential gradient is about-170 mV. 2. Those high energy electrons are able to move against a chemical potential gradient . 3. Water potential gradient between the absorbent and the liquid imbibed is essential for imbibition. 4. Where potential gradients are used to create excited states that decay by light emission. 5. These steep electric potential gradients are the reason for the importance of the DLs. 6. This leads to a small area of very strong potential gradient following the laser pulse. 7. At sea level, the typical potential gradient in fair weather is 120 V / m. 8. Where the first is classically the velocity, and second is classically the force, or potential gradient . 9. The simplest definition for a potential gradient " F " in one dimension is the following: 10. Modelling of water transport between components relies on SPAC, as do studies of water potential gradients between segments.
