Magnetic work takes two forms in the thermodynamics of a paramagnet as developed in many textbooks. We observe that in the case when the lattice energy is excluded, the form δW = BdM cannot be used in a fundamental thermodynamic equation. This shows that there are thermodynamic systems with no fundamental thermodynamic equation. The thermal physics of magnetic systems has been the source of con...

This paper presents an initial exploration of the use and possibility of nm thin SOFC electrolyte structures to enhance cell performance. This is addressed, on one hand, by analyzing the extent of interfacial space-charge areas at the electrode-electrolyte interface. A simple thermodynamic treatment shows that such areas have a characteristic dimension in the order of 0.2 nm so that they can be...

It is well known that neutron star crust in a wide range of mass densities and temperatures is in a crystal state. At a given density, the crystal is made of fully ionized atomic nuclei of a single species immersed in a nearly incompressible (i.e., constant and uniform) charge compensating background of electrons. This model is known as the Coulomb crystal model. In this talk we analyze thermod...

In this work, the solubilities of pharmaceutical cocrystals in solvent/anti-solvent systems were predicted using PC-SAFT in order to increase the efficiency of cocrystal formation processes. Modeling results and experimental data were compared for the cocrystal system nicotinamide/succinic acid (2:1) in the solvent/anti-solvent mixtures ethanol/water, ethanol/acetonitrile and ethanol/ethyl acet...

Depletion forces and macromolecular crowding govern the structure and function of biopolymers in biological cells and the properties of polymer nanocomposite materials. To isolate and analyze the influence of polymer shape fluctuations and penetrability on depletion-induced interactions and crowding by nanoparticles, we model polymers as effective penetrable ellipsoids, whose shapes fluctuate a...

The paper deals with influence of two-scale variations of parameters on the behavior of different dynamical systems. By two-scale we mean parameter oscillations occur in an alternating manner with large and small temporal gradient, on a typical period intervals. The shape of such parameter dependence resembles relaxation oscillations. Parametric instability is revealed under these conditions. W...

Thermodynamic analysis of an ideal air-standard Atkinson cycle with temperature dependant specific heat is presented in this paper. The paper outlines the effect of maximizing power density on the performance of the cycle efficiency. The power density is defined as the ratio of the power output to the maximum cycle specific volume. It showed significant effect on the performance of the cycle ov...
