In this reminiscence I discuss the influence of Henry Eyring and John Barker upon my life and work. Others, especially my family, have been of even greater personal influence. However, these two great and grand men were of tremendous scientific influence. Of course, others who came before Eyring and Barker, especially Boltzmann and van der Waals and later Onsager and Eyring’s contemporary, Kirk...

"Physical chemistry is everything that is interesting," so replied G. N. Lewis, the distinguished mentor of Henry Eyring at Berkeley, California, when queried about the content of this scientific discipline. If this definition be correct, then one who follows the profession of physical chemistry must be sort of a "pan-scientist," and for this title Henry Eyring is well qualified. It is entirely...

Historically, two equations have been used for predicting reverberation times, Sabine and Eyring. A precise means is presented for determining Eyring absorption coefficients alpha(eyring) when the Sabine coefficients alpha(sabine) are known, and vice versa. Thus, either formula can be used provided the absorption coefficients for the Sabine formula are allowed to exceed 1.0. The Sabine formula ...

This study compares the film thickness, lubricant temperature, and traction curves of two groups commonly used constitutive models for lubricants in thermo-elastohydrodynamic lubrication (TEHL) modelling. The first group consists Tait equation state, Doolittle Newtonian viscosity model, Carreau shear thinning model. second includes Dowson Roelands–Houpert Eyring simulations were conducted using...

The present work focuses on the attributes of flow, heat, and mass transfer together with double diffusive Cattaneo–Christov mechanism regards to their applications. aim this study is investigate non-Newtonian Powell–Eyring fluid taking into account twofold impact heat generation viscous dissipation due an extensible sheet. chemical reaction between particles variable properties assumed in stud...

A stagnation-point flow of a Powell–Eyring nanofluid along vertical stretching surface is examined. The buoyancy force effect due to mixed convection taken into consideration with the Brownian motion and thermophoresis effect. investigated under active passive controls nanoparticles at surface. associating partial differential equations are converted set nonlinear, ordinary using similarity con...

The internal rotations around the some within a ylide involving theophylline has been studied using the dynamic 1H NMR spectroscopic technique in different temperatures. The kinetic and activation quantities were calculated. Arrhenius, Eyring and classic methods were applied for isomers. compared for carbon-carbon double, carbon-carbon single bond for Z isomer. The results obtained by classic m...
