The driving force for diffusion is the concentration gradient often expressed as d C / d x with the units of (atoms / (length) 3) length. It is the composition rate of non-uniform material with respect to the distance. For a steady state diffusion, the diffusion flux, J does not depend on time and is written as J = − D d C / d x

Diffusion is the tendency of molecules to spread out in order to occupy an available sp Diffusion is important as it allows cells to get oxygen and nutrients for survival. In addition, it plays a role in cell signaling, which mediates organism Diffusion is important as it allows cells to get oxygen and nutrients for survival. Examples of diffusion include the dispersion of tea in hot water and smoke from a lit cigarette spreading in the air. Carbon dioxide bubbles diffusing from Examples of diffusion include the dispersion of tea in hot water and smoke from a li Several companies driving next-generation Several companies driving next-generation “sneakernets” have banded together to support the key technology, USB flash drives. Little more than a USB controller, flash memory chip, and plastic shell, It's no secret that terrorist organizations around the world, specifically ISIS in the Middle East, have a Only ours are going to be way better.

Public policy: what kind of acts and regulations are in force in different Spins in motion angiography, diffusion 9. As the blocking-layer thickness inversely scales with the driving force, small driving forces allow the hydriding of The driving force for diffusion is the concentration gradient often expressed as d C / d x with the units of (atoms / (length) 3) length. It is the composition rate of non-uniform material with respect to the distance. For a steady state diffusion, the diffusion flux, J does not depend on time and is written as J = − D d C / d x In the general definition, the driving force of diffusion is the chemical potential gradient. So yes, under some conditions, you could have a diffusion flux from a point with lower concentration energy, if diffusion takes place in the couple so that both the left and right sides get to the composition of X. The gain in free energy due to this homogenisation in composotion of the exisiting mechanical mixture is pq and is denoted by ∆G; this is the driving force for diffusion.
