Diffusion in confinement: agreement between experiments better than expected.
نویسندگان
چکیده
The diffusion of alkanes in nanoporous materials as measured by different experimental techniques is thought to be highly dependent on the measuring technique employed. However, when the data are corrected for the loading at which the measurement was performed, the different data series correspond with each other much better than expected.

Fluorescence correlation spectroscopy diffusion laws to probe the submicron cell membrane organization.
To probe the complexity of the cell membrane organization and dynamics, it is important to obtain simple physical observables from experiments on live cells. Here we show that fluorescence correlation spectroscopy (FCS) measurements at different spatial scales enable distinguishing between different submicron confinement models. By plotting the diffusion time versus the transverse area of the c...
متن کاملInvestigation and Simulation of the Effects of Dispersion and Transmittance angles on the Solar Cells Quantum Efficiency
In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation r...
متن کاملEffective temperatures and the breakdown of the Stokes-Einstein relation for particle suspensions.
The short- and long-time breakdown of the classical Stokes-Einstein relation for colloidal suspensions at arbitrary volume fractions is explained here by examining the role that confinement and attractive interactions play in the intra- and inter-cage dynamics executed by the colloidal particles. We show that the measured short-time diffusion coefficient is larger than the one predicted by the ...

In this research, the capability of new approach of making ridge waveguides in lithium niobate by Argon physical etching and diffusion of titanium is investigated. For this purpose, the proportion of light mode confinement in the ridge section is measured and compared to simulation results. Also the effect of ridge wall defects -which is a challenge of this kind of waveguides- in light power di...
متن کاملبررسی تأثیر محصورشدگی بتن در رفتار غیرخطی دیوارهای برشی بتن‌آرمه بالدار
Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...
