In this paper, the solubility of NaCl in water is evaluated by using computer simulations for three different force fields. The condition of chemical equilibrium (i.e., equal chemical potential of the salt in the solid and in the solution) is obtained at room temperature and pressure to determine the solubility of the salt. We used the same methodology that was described in our previous work [E...

In this study, the solubility of CO2 in DEA in the presence and absence of choline chloride was reported at different temperatures of 276.15, 298.15, 313.15, and 333.15 K, and pressure range of 4-15 bar. The solubility of CO2 was evaluated using the pressure decay method in a batch isochoric stirred absorption cell. Also, the design of experiments performed with Qualitek-4 software using the Ta...

Poor water solubility and low transfection efficiency of chitosan are major drawbacks for its use as a gene delivery carrier. PEGylation can increase its solubility, and folate conjugation may improve gene transfection efficiency due to promoted uptake of folate receptor-bearing tumor cells. The aim of this study was to synthesize and characterize folate-poly(ethylene glycol)-grafted chitosan (...

The aim of this study was to investigate changes in the microbiological and physiochemical characteristics in Egyptian salted-fermented fish (Feseikh) during processing, ripening and storage. Isolation of total viable bacteria, Enterobacteriaceae, lipolytic bacteria, proteolytic bacteria, total spore forming bacteria (CFU/g) and Clostridium perfringens (MPN) from fish flesh, fish intestine and ...

The compatibilities of polymer blends, Polypropylene(PP) and Polyamide12(PA12), was simulated by molecular dynamics(MD) simulations. Density, cohesive energy density (CED) ,and solubility parameters(δ) of pure substances and PP/PA12 blends were calculated by MD simulations with the COMPASS force field for the prediction of polymer blends compatibility . Results showed that PP/PA12 is not miscri...
