Measuring thermodynamic length [PDF]

open access: yes, 2007
Thermodynamic length is a metric distance between equilibrium thermodynamic states. Among other interesting properties, this metric asymptotically bounds the dissipation induced by a finite time transformation of a thermodynamic system.

The magnesium-palladium-silver system: Thermodynamic properties of the liquid phase [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2023
A drop calorimetry method was used to measure the partial and integral mixing enthalpies of Ag-Mg-Pd liquid solutions. The experiments were performed for six separate series of liquid alloys starting from the binary alloys with constant xAg/xMg ratios ...
