Temperature-dependent thermal properties of spark plasma sintered alumina [PDF]
In this work, we report temperature-dependent thermal properties of alumina powder and bulk alumina consolidated by spark plasma sintering method. The properties were measured between room temperature and 250ºC using a thermal constants analyzer.

Magnetization, Band Gap and Specific Heat of Pure and Ion Doped MnFe2O4 Nanoparticles
We have studied the magnetic properties of ion doped MnFe2O4 nanoparticles with the help of a modified Heisenberg model and Green’s function theory taking into account all correlation functions.

Non-Universality of the Specific Heat in Glass Forming Systems [PDF]
We present new simulation results for the specific heat in a classical model of a binary mixture glass-former in two dimensions. We show that in addition to the formerly observed specific heat peak there is a second peak at lower temperatures which was ...

Heat capacity of liquids: A hydrodynamic approach
We study autocorrelation functions of energy, heat and entropy densities obtained by molecular dynamics simulations of supercritical Ar and compare them with the predictions of the hydrodynamic theory.

Specific heat of a PIN-PMN-PT single-crystal up to 500K [PDF]
The temperature dependence of the specific heat of the single crystal Pb(In0.5Nb0.5)O3-Pb(Mg1∕3Nb2∕3)O3-PbTiO3 (PIN-PMN-PT) was obtained at 80–500K by means of ac-calorimetry, and comparison with the calorimetric data for PMN was made, allowing one to ...

Entanglement area law from specific heat capacity [PDF]
We study the scaling of entanglement in low-energy states of quantum many-body models on lattices of arbitrary dimensions. We allow for unbounded Hamiltonians such that systems with bosonic degrees of freedom are included.

Action and Entropy in Heat Engines: An Action Revision of the Carnot Cycle
Despite the remarkable success of Carnot’s heat engine cycle in founding the discipline of thermodynamics two centuries ago, false viewpoints of his use of the caloric theory in the cycle linger, limiting his legacy.
