Inconsistency of ammonium–sulfate aerosol ratios with thermodynamic models in the eastern US: a possible role of organic aerosol

open access: yes, 2017
. Thermodynamic models predict that sulfate aerosol (S(VI)  ≡  H2SO4(aq) + HSO4−+ SO42−) should take up available ammonia (NH3) quantitatively as ammonium (NH4+) until the ammonium sulfate stoichiometry (NH4)2SO4 is close to being reached. This uptake of

Fine-particle pH for Beijing winter haze as inferred from different thermodynamic equilibrium models

open access: yesAtmospheric Chemistry and Physics, 2018
. pH is an important property of aerosol particles but is difficult to measure directly. Several studies have estimated the pH values for fine particles in northern China winter haze using thermodynamic models (i.e., E-AIM and ISORROPIA) and ambient ...

Thermodynamic models to accurately describe the PVTxy-behavior of water / carbon dioxide mixtures

open access: yes, 2017
Carbon dioxide/water (CO2/H2O) mixtures are of much interest in carbon capture and storage, atmospheric science, in the description of human lungs and in the processing of food and beverages.

Approaches to thermodynamic property calculation of complex fluids: literature review

open access: yesTạp chí Khoa học và Công nghệ
Thermophysical properties of industrially complex fluids whose composition is always ill-defined are in practice predicted by using thermodynamic models. To ensure the prediction accurately and reliably, a three-step procedure to obtain the properties of

The thermodynamic model for nuclear multifragmentation [PDF]

open access: yesPhysics Reports, 2005
A great many observables seen in intermediate energy heavy ion collisions can be explained on the basis of statistical equilibrium. Calculations based on statistical equilibrium can be implemented in microcanonical ensemble (energy and number of particles in the system are kept fixed), canonical ensemble (temperature and number of particles are kept ...
