Journal of Geometric Analysis, 2011
From the author's abstract: We propose an answer to a question raised by F. Burstall: Is there any interesting theory of isothermic submanifolds of \(\mathbb{R}^n\) of dimension greater than two? We call an \(n\)-immersion \(f(x)\) in \(\mathbb{R}^m\) isothermic\(_k\) if the normal bundle of \(f\) is flat and \(x\) is a line of curvature coordinate ...

Adsorption isotherms—A critique
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1973Summary The possibility or the impossibility of separating the particle and the electrode interactions is discussed in a wider context of the effects due to any two interaction potentials on the equation of state. The involved nature of the pressure dependence on two individually definable forces is illustrated through the Percus Yevick results for ...

Isothermal and non‐isothermal crystallization behavior of PET nanocomposites
Polymer Engineering & Science, 2011AbstractPolyethylene terephthalate (PET)/clay nanocomposites (PCNs) containing 1 wt% Cloisite 30B (C30B) were prepared via melt compounding. Modulated differential scanning calorimetry (MDSC) for isothermally crystallized samples revealed that the third endotherm at the highest temperature may be attributed to the recrystalization and melting of ...

Quantitative Characterization of Adsorption Isotherms Using Isothermal Microcalorimetry
Journal of Pharmaceutical Sciences, 1996The integral heat of adsorption of water vapor on sodium benzoate samples was determined at various partial vapor pressures using a heat conduction microcalorimeter. An equation is presented to describe the calorimetric integral heat response (mJ/g of solid) as a function of relative humidity.

ISOTHERMAL AND NON-ISOTHERMAL MULTICOMPONENT ADSORPTION KINETICS
Chemical Engineering Communications, 1990The model equations in the relaxation form for the multicomponent kinetics of isothermal and non-isothermal adsorption, taking into account all major distinctive features of the interphase heat and mass exchange inside porous grains and at their surface (see points 1 to 4 below) for P (“pore”) and S (“solid”) models of mass transfer within porous ...

Isothermal and non-isothermal crystallization of a fresnoite glass
Journal of Non-Crystalline Solids, 2013Abstract Several analytical models have been widely applied to determine the activation energy of crystallization, E , and the Avrami index, n . In this work, the parameters E and n for the crystallization of fresnoite (2BaO·TiO 2 ·2SiO 2 ) glass were calculated using different approaches (Ozawa, Kissinger, and Matusita & Sakka).

Experiments on isothermal and non-isothermal spreading
Journal of Fluid Mechanics, 1993Experiments are performed on axisymmetric spreading of viscous drops on glass plates. Two liquids are investigated: silicone oil (M-100), which spreads to ‘infinity’, and paraffin oil, which spreads to a finite-radius steady state. The experiments with silicone oil partly recover the behaviour of previous workers’ data; those experiments with paraffin ...

Physical Review E, 2002
The existence of steady, spherically symmetric wave fronts ("isothermal flame balls") in chemical reaction systems exhibiting autocatalysis is demonstrated. Such solutions require relatively high kinetic orders p with respect to the autocatalytic species, with p>5, but occur even with equal diffusion coefficients. The flame balls are unstable, but have
