Recently a new solute and solvent transmembrane cellular transport model accounting for non-dilute solute concentrations was introduced. This model depends on a second or third order polynomial expansion in mole fraction of Gibbs energy for solutes and
The article provides a perspective of chemical process and product design on demand, its implementation and impact in addressing modern challenges faced by chemical industry. The concepts of Global Information Systems in Science and Engineering in

ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported recently in this journal. In the present paper we describe the first steps in implementation of an algorithmic approach to assist
Hildenbrand and coworkers have shown recently that the vapor above solid ammonium nitrate includes molecules of NH4NO3, not only NH3 and HNO3 as previously believed. Their measurements led to thermochemical values that imply an enthalpy change of D298 = 98
In 2006, the CIPM clarified the definition of the kelvin by specifying the isotopic composition of the water to be used in the realisation of the triple point. At the same time, the Consultative Committee on Thermometry gave recommended values for the
Isothermal Titration Calorimetry was used to study the thermodynamics of hybridization on DNA-functionalized colloidal gold nanoparticles. When compared to the thermodynamics of hybridization of DNA that is free in solution, the differences in the values
The equilibria of energetically non-equivalent states of molecules conformational, orientational, configurational significantly contribute to the heat capacity changes at the phase transitions such as crystal liquid, rigid crystal plastic crystal, glass
In this paper, the piezoelectric ceramics mounted on the endplates of a cylindrical resonator were used as the source and detector for acoustic speed measurements. The perturbations of the longitudinal gas modes of the cavity due to the compliance of the

The software provides thermophysical property data for 105 selected explosive materials. The product is the result of an extensive literature search and data capture coupled with the dynamic data evaluation concept implemented in the ThermoData Engine
The thermodynamic properties of a hydrofluoro-olefin (HFO) refrigerant are presented. The p-ρ-T behavior of high-purity (99.993 %) R1234ze(E) was measured from 240 K to 420 K with pressures to 15 MPa using a two-sinker densimeter. The measurements extend

Microcalorimetry, high-performance liquid chromatography (HPLC), and liquid chromatography-mass spectrometry (LC-MS) have been used to conduct a thermodynamic investigation of the hydrolysis reactions: 1-naphthyl acetate(aq) + H2O(l) = 1 naphthol(aq) +
A combination of classical thermodynamics and molecular theory was used to calculate the enhancement factor (ratio of partial pressure to saturated vapor pressure) for liquid mercury in equilibrium with air at standard atmospheric pressure in the

Rosenfeld [Phys. Rev. A 15, 2545 (1977)] originally noticed that casting the transport coefficients of simple monatomic, equilibrium fluids in a specific dimensionless form makes them approximately single-valued functions of excess entropy. This
