The solubility of scCO2 in solid (298 K) and melted (323 K) PEG, in the pressure range (7 to 25) MPa was measured using a Magnetic Suspension Balance. The phase behavior of the CO2 + PEG system was modeled by using Sanchez-Lacombe and SAFT EOS. The results show a good solubility of CO2 in polymer and a good accuracy of the thermodynamic models in describing the phase equilibrium of the working system. The experimental data are also in good agreement

This study focuses on the connection between biocompatibility and corrosion resistance for a Co-Cr-Mo alloy used for biomedical applications. Electrochemical, surface analysis and in vitro tests were used to estimate the stability of the alloy in simulated physiological environment (artificial saliva, Hank solution), for different pH and surface preparation conditions, and its behavior in the presence of fibroblast cells. The results prove a good
