Every biological and physicochemical process occurring in a fluid phase depends on the diffusion coefficient (D) of the species in solution. In the present work, a model to describe and fit the behaviour of D ${D}$ as a function of structure and extensive thermodynamics parameters in binary solutions of linear chain organic molecules is developed. Supporting experimental and computational evidences for this model are obtained by measuring D ${D}$ for a series of n ${n}$ ‐alcohols through a novel surface plasmon resonance method and molecular dynamics simulations. This allows to propose a kind of combined analysis to explain the dependence of D ${D}$ on various thermodynamic and structural parameters. The results suggest that for small linear systems in the range from 0 to 200 g mol−1 and under the assumption that the diffusive activation energy is a linear function of mass, D ${D}$ is strictly dependent on the molecular shape and on the relative strength of the solute‐solvent intermolecular forces represented by a parameter named R. The newly proposed approach can be utilized to characterize and monitor progressive changes in physicochemical properties for any investigated species upon increasing the dimension of the aggregate/molecule along a certain direction.

This article discusses a study conducted on the concentration profile inside a tubing system of a surface plasmon resonance (SPR) system. The researchers used newly designed experiments to detect the concentration profile and determine the diffusion coefficients of linear chain molecules in water. They also developed a model based on Eyring's theory of absolute rates, which introduced a fitting parameter to explore the interplay between intermolecular forces, rotational hindrance, and diffusion in aqueous solutions of linear chain organic molecules. The full research article provides more detailed information on the study. [Extracted from the article]

Wavefront shaping technology can correct for wavefront distortion in turbid media and restore the diffraction‐limited imaging. However, the extent of each correction's validity, or the isoplanatic patch, in bone is unknown. In this paper, we present 1) direct measurement and 2) an in‐situ modeling method of the isoplanatic patch in the murine skull.
