Thermodynamics of Weakly Coherent Collisional Models [PDF]
Physical Review Letters, 2019 We introduce the idea of weakly coherent collisional models, where the elements of an environment interacting with a system of interest are prepared in states that are approximately thermal, but have an amount of coherence proportional to a short system-environment interaction time in a scenario akin to well-known collisional models.

Thermodynamic modeling of the CaO-SiO2-CaCO3-H2O closed and open system at 25ºC
Materiales de Construccion, 2003 This paper reports on a thermodynamic calculation-based study of the CaO-SiO2-CaCO3-H2O closed system at 25 °C, conducted to determine the range of carbonate ion concentrations at which each phase of the system is stable. Portlandite (CH) and the CSH gel

Phase stability of hafnium oxide and zirconium oxide on silicon substrate
, 2007 Phase stabilities of Hf-Si-O and Zr-Si-O have been studied with first-principles and thermodynamic modeling. From the obtained thermodynamic descriptions, phase diagrams pertinent to thin film processing were calculated.

Artificial neural networks and physical modeling for determination of baseline consumption of CHP plants [PDF]
, 2014 An effective modeling technique is proposed for determining baseline energy consumption in the industry. A CHP plant is considered in the study that was subjected to a retrofit, which consisted of the implementation of some energy-saving measures. This

Modeling piperazine thermodynamics
Energy Procedia, 2011 AbstractA thermodynamic model in Aspen Plus® was developed to predict properties of piperazine (PZ)/H2O and PZ/H2O/CO2. A sequential regression was performed to represent recently acquired loaded and unloaded heat capacity, CO2 solubility, CO2 activity coefficient, speciation, and unloaded and loaded amine volatility data.
