Diffusion coefficient(in porous media).
Diffusion coefficient grows larger when turbulence grows stronger.
The significant thing here is that the diffusion coefficient can be negative.
Here, the diffusion coefficient is a measure for expressing patterns in which particles scatter randomly.
So, by DIS one has determined the intensity weighted diffusion coefficient.
Image 2: Dependence of diffusion coefficient on turbulence strength obtained in experiments using electrical convection.
They can then calculate the apparent diffusion coefficient(ADC).
Focus is on the effective diffusion coefficients for the z direction velocity w, while all other truncation errors are ignored.
This points to the need for an Apparent Diffusion Coefficient(ADC).
Due to their small diffusion coefficient, the thermal diffusion technology used for the Si process is not applicable to the SiC device process.
The speed of movement of copperatoms is determined by what is known as the diffusion coefficient.
Also, this diffusion coefficient was found to be about the same as the coefficient in the main waters estimated by long-term data on salinity alteration in previous studies.
Solubility od disperse dyes in supercritical carbon dioxide and diffusion coefficient in polymer.
Discovery of new temperature dependency as a result of highly accurate diffusion coefficient measurements, providing valuable data for investigation of liquid diffusion mechanism of atoms and molecules.
Utilizing such advantages in the electrical convection, first,we conducted an experiment that measured the diffusion coefficient.
Ductal®s hydraulic conductivity coefficient, air permeability coefficient, and chloride ion diffusion coefficient are markedly lower compared with normal concrete, and resistance to mass transfer is dramatically higher.
Thinking about it for a moment, since both atoms move, it would seem that their frequency of meetingwould be proportional to the second power of the diffusion coefficient, but this is not so.
In his research on ionic conduction,Dr. Kingery measured the diffusion coefficient of oxygen ions in oxides, elucidating the behavior of oxygen ions and lattice defects and making an important contribution to analysis of the diffusion phenomenon.
The frequency of two copper atoms meeting(the reaction rate) is proportional to the second power of the number of copper atoms andfirst power of their speed of movement the diffusion coefficient.
Specially designed sequences were developed byBruker which exploit differences in both relaxation rates and diffusion coefficients for water and lipids leading to improved accuracy of the measurements.
FV1200 Diffusion Measurement Package| Olympus Life Science The optional diffusion measurement package for the FLUOVIEW FV1200 confocal laser scanning microscope enables data acquisition and the analysis of molecular interactions andconcentrations by calculating the diffusion coefficients of molecules within a cell.
A result of the experiment is that accompanying the change from a formed convection to a strong turbulent flow,the particle diffusion coefficient grew increasingly. We observed that the transport coefficient was in a nearly proportional relationship with the Rayleigh number which expresses the strength of the turbulence.
The phenomenon that matter(short chain) was transported along one helical chain(long chain) of poly(substituted phenylacetylene)by single-molecule imaging using FS-AFM was observed, and diffusion coefficient were measured.
Further, they improved the parameterization by applying the observed oceandata to the formula of parameterization of the vertical eddy diffusion coefficient, which has been gained from numerical experiments by Kimura et al.
In particular, he explained that liquid phase sintering, the most important process in ceramic manufacturing, proceeds in three stages-the wetting of particles through liquefaction, particle rearrangement, and dissolution and precipitation-providing the first theoretical elucidation of the essence of this process. Through this line of research, he also revealed that the key factor controlling the sintering mechanism of ceramics and the microstructures andphysical properties of sintered materials is the diffusion coefficient of the component ions.
Therefore, in this study, they implemented observations of micro structures of the oceans, and proposed a Richardson number as a newindex as the result of calculating the vertical eddy diffusion coefficient of the water temperatures and salinity and as the result of observing CTD and LADCP.
However, the buoyancy Reynolds number is a value gained from observation of micro structures of an ocean, which is not suitable touse as the index giving vertical eddy diffusion coefficient due to double diffusive convection.
