A review. This research group is working towards understanding the fundamental physicochem. mechanisms of trace metal biouptake by aquatic microorganisms in natural systems. Research is currently focused on identifying under what conditions uptake fluxes a ...
We consider a heterogeneous model for the dynamics of a blood solute both in the vascular lumen and inside the arterial wall. In the lumen, we consider an advection-diffusion equation, where the convective field is provided by the velocity of blood, which ...
A transport equation is derived which describes the behavior of the nanostructured metal oxide films in a photoelectrochem. cell. A detailed anal. of the charge compensation mechanism necessarily leads to a transport equation with characteristics similar t ...
The factors controlling leachate composition of cement stabilized air pollution control (APC) residues (41% APC residues, 22% cement, 3% Na2CO3, and 32% water, w/w) have been investigated both in the laboratory ansi in a pilot landfill. Batch leaching and ...
Ag aggregation on Ag(111), Pt(111), and 1 ML Ag pseudomorphically grown on Pt(111), has been studied with variable temperature STM. These systems all have in common that dendritic patterns with trigonal symmetry rather than randomly ramified aggregates, wh ...
Particle and heat transport in a low collisional plasma confined by a partially stochastic magnetic field are analysed. We show that the particle diffusion is ambipolar. Moreover near stochastic threshold, the electron heat diffusivity chi(e) is enhanced, ...
Electrochemical techniques were applied to a coulometric titration cell to study oxygen nonstoichiometry and transport in the perovskite-type oxide La0.4Ba0.6Fe0.8Co0.2O3-delta. Slow scan voltammetry (3mV/s) was used to obtain oxygen nonstoichiometry vs. t ...
Oxygen diffusion is treated in a dense electronically conducting cobaltate pellet blocked ionically on one surface, electronically on the other, and sealed on its cylindrical periphery. A procedure is developed for extracting the chemical diffusion and sur ...
The feasibility of removing water from azeotropic mixts. is explored. Although the selectivity of membrane distn. processes is largely detd. by vapor liq. equil. (VLE), differences in diffusion rates across the membrane and an eventual addnl. gas gap may s ...
Light propagation in two-layered turbid media having an infinitely thick second layer is investigated in the steady-state, frequency, and time domains. A solution of the diffusion approximation to the transport equation is derived by employing the extrapol ...
