On the Kinetics of Evaporation [PDF]

open access: greenThe Journal of Physical Chemistry, 1952
The kinetics of evaporation of liquids has been reconsidered from the point of view of classical kinetic reactions and also by application of the theory of absolute reaction rates. It is shown that evaporation treated as a unimolecular rate process, with a rate proportional to the surface concentration of energetic molecules, leads to the Knudsen ...

Kinetics of Social Contagion [PDF]

open access: yesPhysical Review Letters, 2015
Diffusion of information, behavioral patterns or innovations follows diverse pathways depending on a number of conditions, including the structure of the underlying social network, the sensitivity to peer pressure and the influence of media. Here we study analytically and by simulations a general model that incorporates threshold mechanism capturing ...

Regularity of kinematic data between single and dual-task treadmill walking in people with Parkinson’s disease

open access: yesJournal of NeuroEngineering and Rehabilitation, 2021
Background Regularity, quantified by sample entropy (SampEn), has been extensively used as a gait stability measure. Yet, there is no consensus on the calculation process and variant approaches, e.g.

Dilation kinetics of glassy, aromatic polyimides induced by carbon dioxide sorption [PDF]

open access: yes, 1995
Over the past years, the equilibrium sorption of gases in polymers has been intensively studied. Mostly, glassy polymers were investigated because of their excellent selective mass transport properties.

Correlations between Growth Kinetics and Microstructure for Scales Formed by High-Temperature Oxidation of Pure Nickel. II. Growth Kinetics [PDF]

open access: yes, 2002
The oxidation kinetics of high-purity nickel were studied between 500 and 1200°C, in pure oxygen at atmospheric pressure, for aûerage oxide-scale thicknesses of 1, 5, 10, and 30 μm.
