Diffusing diffusivity: a model for anomalous, yet Brownian, diffusion.
Wang et al. [Proc. Natl. Acad. Sci. U.S.A. 106, 15160 (2009)] have found that in several systems the linear time dependence of the mean-square displacement (MSD) of diffusing colloidal particles, typical of normal diffusion, is accompanied by a non-Gaussian displacement distribution G(x,t), with roughly exponential tails at short times, a situation they termed “anomalous yet Brownian” diffusion...
متن کاملEntropy, diffusivity and the energy landscape of a waterlike fluid.
Molecular dynamics simulations and instantaneous normal mode (INM) analysis of a fluid with core-softened pair interactions and waterlike liquid-state anomalies are performed to obtain an understanding of the relationship between thermodynamics, transport properties, and the potential energy landscape. Rosenfeld scaling of diffusivities with the thermodynamic excess and pair correlation entropy...
متن کاملExcess Entropy Scaling Law for Diffusivity in Liquid Metals
Understanding how dynamic properties depend on the structure and thermodynamics in liquids is a long-standing open problem in condensed matter physics. A very simple approach is based on the Dzugutov contribution developed on model fluids in which a universal (i.e. species-independent) connection relates the pair excess entropy of a liquid to its reduced diffusion coefficient. However its appli...
متن کاملDiffusivity Measurements of Human Methemoglobin
Experimental measurements of the diffusion coefficient of human methemoglobin were made at 25 degrees C with a modified Stokes diaphragm diffusion cell. A Millipore filter was used in place of the ordinary fritted disc to facilitate rapid achievement of steady state in the diaphragm. Methemoglobin concentrations varied from approximately 5 g/100 ml to 30 g/100 ml. The diffusion coefficient in t...
متن کاملTime-dependent diffusivity of boron in silicon oxide and oxynitride
The diffusivities of boron in silicon oxide and oxynitride have been determined from secondary ion mass spectroscopy measurements of annealed metal-oxide-silicon structures. The results clearly show a decrease in diffusivity with increasing anneal time which is approximately exponential in form. This effect implies a similar time dependence in the concentration of a secondary species, such as h...
