Applied Thermodynamics: Grain Boundary Segregation

Chemical composition of interfaces—free surfaces and grain boundaries—is generally described by the Langmuir–McLean segregation isotherm controlled by Gibbs energy of segregation. Various components of the Gibbs energy of segregation, the standard and the excess ones as well as other thermodynamic state functions—enthalpy, entropy and volume—of interfacial segregation are derived and their phys...

Thermodynamics of ferrofluids in applied magnetic fields.

The thermodynamic properties of ferrofluids in applied magnetic fields are examined using theory and computer simulation. The dipolar hard sphere model is used. The second and third virial coefficients (B(2) and B(3)) are evaluated as functions of the dipolar coupling constant λ, and the Langevin parameter α. The formula for B(3) for a system in an applied field is different from that in the ze...

A Theory of Mapping from Structure to Function Applied to Engineering Thermodynamics

This paper presents a theoretical framework for mapping from structure to function in engineering domains . We argue that a generative approach grounded in Qualitative Process Theory produces useful functional explanations . Useful explanations are articulate, in that they enable the user to explore their theoretical justifications and they support counterfactual reasoning . These explanations ...

A review of quantum thermodynamics

In this article, we present a brief and elementary review of quantum thermodynamics and its achievements and challenges. This review includes an introduction to some fundamental concepts such as internal energy, heat, work, entropy, entropy production, thermal equilibrium, second law of quantum thermodynamics, relation between thermodynamics and information theory, as well as a discussion of ho...
