Direct loading diffusion studies confirmed that hydrogels produced by direct incorporation of cytochrome c with the aqueous SELP solution did not significantly influence the release behavior compared to equilibrium loaded hydrogels.
The problem leads to three different time histories associated with the strong coupling between the mechanical loading, diffusion of a fluid (water), and the degradation.
Due to its simplicity the model can be used to help seek for possibilities of optimizing the cell performance of a passive DMFC by studying impacts from variations of the design parameters such as membrane thickness, catalyst loading, diffusion layers type and thicknesses.
Gas solubility coefficients generally increased with increasing particle loading, whereas diffusion coefficients decreased with increasing particle loading.
For the case of Fe3O4 nanoparticles that are 10 nm in diameter, the SiNT sidewall pore dimensions are insufficient to permit loading by diffusion through this orifice and thus the SiNT film must be removed from the substrate prior to loading of this sample.
In this case, the mechanical response of rubbers is affected by the interaction existed between mechanical loading and diffusion of liquid into the material.
Effects of various transport parameter as well as other factors such as catalyst loading, gas diffusion layer thickness and liquid water permeability on the transient evolution of major model properties and cell performance are investigated in detail.
Second, for a given platinum loading, the diffusion area is higher when the mass ratio of platinum to carbon nanotube decreases.
In order to mimic the environment and the external stimuli which the stent is subject to, the polymers are subject to three different types of external stimuli, that are due to prescribed mechanical loading, the diffusion of water, and the degradation that occurs over a period of time, ensuring that we have a strong coupling between the deformation, degradation, and diffusion response.
