Accurate theoretical predictions of the volume-fraction dependence during diffusion-controlled coarsening of a polydisperse assembly of particles ... the depletion of solute decreases as the ...

Called Infrared Diffusion-Ordered ... brownian motion of microscopic particles. The IR-DOSY spectrometer creates a spatially inhomogeneous distribution of solute molecules using a simple yet ...

Save guides, add subjects and pick up where you left off with your BBC account. Particles in a liquid and a gas move continuously. Because of this movement, particles will spread themselves evenly ...

Solute transport through fractured porous rocks can be described by advective-dispersive transport through the fractures and diffusive transport through the unfractured matrix. The effect of matrix ...

Instead, we introduce a new concept, called “solute age", that represents the amount of time that sorbing and/or decaying contaminant particles have been in the aquifer. We developed a method to ...
