Universality, scaling and collapse in supercritical fluids [PDF]
, 2019 The Supercritical Fluid (SCF) is known to exhibit salient dynamic and thermodynamic crossovers and inhomogeneous molecular distribution. But the question as to what basic physics underlies these microscopic and macroscopic anomalies remains open. Here, using an order parameter extracted by machine learning, the fraction of gas-like (or liquid-like ...

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 ...

Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]
, 2012 In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.

A corresponding-state framework for the structural transition of supercritical fluids across the Widom delta [PDF]
J. Chem. Phys. 150, 154503 (2019), 2018 This work proposes a classification algorithm based on the radical Voronoi tessellation to define the Widom delta, supercritical gas-liquid coexistence region, of polyatomic molecules. In specific, we use a weighted mean-field classification method to classify a molecule into either gas-like or liquid-like.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...
