Measurements of Vortex Diffusivity in 2d Superfluid Helium-4
… using as our adjustable parameters the vortex diffusivity D and the free vortex creation time (tau)(,free). We find D to be dependent on superfluid thickness and temperature (for 90 mK < T < 600 mK), but to be independent of superfluid flow velocity, frequency of the oscillating velocity field, …

Experimental estimate of the diffusivity of Vascular Endothelial Growth Factor
The diffusivity of Vascular Endothelial Growth Factor (VEGF) is a number that is very important in determining the transport of VEGF. The transport of VEGF determines crucial processes such as angiogenesis and vasculogenesis. This study aimed at obtaining an estimate of the diffusivity of VEGF by …

Sensitivity of climate change to diapycnal diffusivity in the ocean
The diapycnal diffusivity of the ocean is one of the least known parameters in cur- rent climate models. Measurements of this diffusivity are sparse and insufficient for compiling a global map. Inferences from inverse methods and energy budget calculations suggests as much as a factor of 5 …

High Permeability/High Diffusivity Mixed Matrix Membranes For Gas Separations
… properties as well as permeability by increasing diffusivity. Overall increases in permeance and diffusivity for all tested gases suggested that carbon nanotubes can provide high diffusivity tunnels in the CNT within the polymer matrix. This result agreed well with molecular simulation …

Profiling of Relaxation Time and Diffusivity Distributions with Low Field NMR
Nuclear magnetic resonance (NMR) is a common tool utilized in core analysis. NMR can reveal important information about pore structure, fluid configuration and wettability. However, standard NMR core analysis techniques look at the sample as a whole or only at thin slices. Two NMR pulse sequences …

An electrochemical investigation of the chemical diffusivity in liquid metal alloys
… these liquid alloys, in particular the chemical diffusivity, must be known accurately so that it can be used as input in computational simulations to avoid the nucleation of any solids. Unfortunately, the dominant experimental methods for measuring diffusion in liquid metals today are unreliable …
