the basics of quantum mechanics and statistical thermodynamics were used to predict the potential energy and intermolecular forces of asphaltene molecules. the parameters associated with the chemical structure were also estimated for a specific asphaltene molecule to predict the mie potential function. based on the structural results, a new form of the virial eos with peneloux correction was de...

The rate/temperature dependent fracture behaviour of plain and glass-filled polystyrene has been investigated over the crack speed (a) range of 10 -6 to 10 -2 m sec -1 and in the temperature (7-) range of 296 to 363 K. The Kc (a, T) relationships obtained, where Kc is the stress intensity factor at fracture, are shown to follow those given by the Williams/ Marshall relaxation crack growth model...

In the processes of carbon capture and storage, sulfur nitrogen oxides (SOx NOx) would be possibly injected with CO2 depending on origin CO2. The thermodynamic properties these gases in saline aquifer are poorly known. Solubility is one key parameter to implemented geochemical codes modelling long-term evolution after injection. solubility NO known only at atmospheric pressure. this study, wate...

This Article contains errors in Figs 2 and 3. Figure 2d was inadvertently duplicated in Fig. 2e; Fig. 3c was inadvertently duplicated in Fig. 3b. The correct Figs 2 and 3 appear below as Figs 1 and 2 respectively.

The solvent plays an important role in a given chemical reaction. Since most reaction in nature occur in the mixed-solvent systems, a comprehensive principle for solvent optimization was required. By calculating the Hansen solubility parameters (HSP) distance Ra, we designed a model experiment to explore the influence of mixed solvents on the chemical synthesis. The synthesis of polydopamine (P...
