Modeling Heat Capacity of Supercritical Fluids: A Phonon Theory Approach [PDF]
arXiv, 2023 Recent research shows that liquids and dense supercritical fluids support high frequency shear waves. Here, we proposed a general heat capacity model of supercritical fluids using the latest theoretical findings (the liquid phonon theory). In this theory, heat capacity cv of supercritical fluids is only related to the infinite-frequency shear modulus ...

Journal of Polymer Science, Volume 60, Issue 24, Page 3354-3365, 15 December 2022., 2022 Abstract Epoxidized oils are commonly used in the plastics industry as additives in the formulation of polyvinyl chloride (PVC) and as monomers in the coating industry. They are produced from petrochemical feedstocks or by chemical epoxidation of natural oils. Currently, the synthesis processes of these materials are expensive, utilize volatile organic
