A strategy to compute critical surfaces in highly asymmetrical ternary systems J. Supercrit. Fluids (IF 3.9) Pub Date : 2024-03-12 Pisoni G.O., Cismondi M., Zabaloy M.S.
This work shows that predicting, using a model, the topology and even the existence range of the critical behavior in an asymmetrical ternary system, is practically impossible without a systematic strategy to build through computations the ternary critical surface (T-CS). For this purpose, it is necessary to have robust calculation procedures to compute such surfaces. In this work, a calculation strategy

Foaming behaviors of poly (butylene adipate-co-terephthalate) with methyl methacrylate-co-glycidyl methacrylate as chain extender J. Supercrit. Fluids (IF 3.9) Pub Date : 2024-02-28 Zicheng Wang, Ruijia Wang, Shenzhi Yan, Shulin Sun
As an important biodegradable polymer, how to achieve stable cell morphology and high cell density in the foam of poly(butylene adipate-co-terephthalate) (PBAT) is challenging due to its low mechanical and melt strength. To address this issue, an innovative methyl methacrylate-co-glycidyl methacrylate (MG) copolymer was designed and used as a chain extender due to its strong affinity with carbon dioxide

Leading elliptic relationship for supercritical fluids in the Widom region J. Supercrit. Fluids (IF 3.9) Pub Date : 2024-02-24 Donát M. Takács, Tamás Fülöp, Attila R. Imre
It is well-known that the behaviour of supercritical fluids near the critical point changes considerably in the region around the Widom lines. We have found, for pure fluids, that the relationship between the thermal expansion coefficient and the isothermal compressibility is not only highly nonlinear in this region but in a certain temperature range can also be approximated well at constant pressure

This study investigates the solvation effect on the decarboxylation of -phthalic acid using quantum calculations with a continuum solvation model with varying dielectric constants. Two mechanisms were considered: with and without a catalytic water molecule. The latter had a lower reaction barrier. Increasing the dielectric constant facilitates the hydrogen transfer but impedes C–C bond breaking in
