Fluorescence correlation spectroscopy allows investigating the interaction of charged proteins with charged surfaces of liquid-filled nanochan- nels. Based on a 2-D multi-component diffusion model the bulk and surface diffusion behavior is quantified. ...
Evaporation from porous media is a key process in the hydrologic cycles, waste isolation, biological and food processes and other engineering application. Drying rate and patterns in porous media are strongly influenced by transport properties of the mediu ...
Soil bacterial cells are often found embedded in biosynthesized extracellular polymeric substances ( EPS) forming aggregates or stationary colonies attached to solid surfaces. Soil bacterial aggregation and pooling of resources offer a successful adaptatio ...
The effect of flow regime and fluid morphology (distribution and spatial arrangement) on macroscopic transport properties (effective diffusion coefficient, hydraulic conductivity) was analyzed using a multi-component lattice Boltzmann model. Various flow r ...
In this study, we examine the parameters that govern the overall oxygen flux through a permeation membrane. The chemical diffusion (D) and the surface exchange (k) coefficients for oxygen in La0.6Sr0.4Fe0.8Co0.2O3-d were determined as a function of tempera ...
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 ...
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 ...
Pseudomonas aeruginosa pneumonia is a life threatening complication in mechanically ventilated patients that requires the ability of the bacteria to adhere to, and colonize the endotracheal intubation device. New strategies to prevent or reduce these nosoc ...
A theoretical modeling framework is proposed to follow shape and residual stress evolutions of layered flexible display structures with respect to deposition, ambient temperature and relative humidity conditions. This model couples the mechanical equilibri ...
Passive sampling relies on the uptake of contaminants into appropriate sampling devices along a diffusion gradient without using pumps or bailers. Thus, for example, in groundwater sampling, changes to flow due to pumping can be avoided. If the diffusion g ...
