Thermodynamic approach to liquid-to-glass transformation as an arrest transition in polydisperse solution [PDF]
arXiv, 2022 Thermodynamic multi-component solution solidification approach to liquid-to-glass transition is proposed and actual mechanisms underlying vitrification, other than viscous slowdown, are identified. Due to polydisperse aggregation in liquid state, glass-forming liquids, irrespective of chemical composition, appear to be mixtures of various quasi ...

Thermodynamics of liquids: standard molar entropies and heat capacities of common solvents from 2PT molecular dynamics [PDF]
, 2011 We validate here the Two-Phase Thermodynamics (2PT) method for calculating the standard molar entropies and heat capacities of common liquids. In 2PT, the thermodynamics of the system is related to the total density of states (DoS), obtained from the ...

Thermodynamics and Inflammation: Insights into Quantum Biology and Ageing
Quantum Reports, 2022 Inflammation as a biological concept has been around a long time and derives from the Latin “to set on fire” and refers to the redness and heat, and usually swelling, which accompanies injury and infection.

On the calculation of equilibrium thermodynamic properties and the establishment of statistical-thermodynamically-consistent finite bound-state partition functions in nonideal multi-component plasma mixtures within the chemical model [PDF]
, 2010 The problem of the calculation of equilibrium thermodynamic properties and the establishment of statistical-thermodynamically-consistent finite bound-state partition functions in nonideal multi-component plasma systems is revised within the chemical picture.

A Thermodynamic based and Data Driven Hybrid Network for Gas Turbine Modeling [PDF]
arXiv, 2021 The on-wing engine performance is difficult to track for thermodynamic models because of its inaccurate component maps, and also difficult for data driven methods for their over-fitting to measurement errors. So, we propose a thermodynamic based and data driven hybrid network for gas turbine modeling.

Quantum nature of the critical points of substances
, 2010 Thermodynamics of chemical elements, based on the two-component electron-nuclear plasma model shows that the critical parameters for the liquid-vapor transition are the quantum values for which the classical limit is absent.Comment: 4 pages, no ...

Semi-Holographic Universe [PDF]
, 2010 By assuming that a dark component (dark energy) in the universe strictly obeys the holographic principle, that is, its entropy is one fourth of the apparent horizon, we find that the existence of the other dark component (dark matter) is compulsory, as a

Competitive Adsorption between Polyethylene Glycol and Acid Brilliant Red on Expanded Graphite
E-Journal of Chemistry, 2012 Expanded graphite (EG) adsorbent was prepared with graphite as raw materials, potassium permanganate as oxidant, and vitriol as intercalation compound. Polyethylene glycol (PEG) 10000 and Acid brilliant red 3B (ABR) with obvious difference in molecular ...

Bose-Einstein condensation at constant temperature
, 2004 We present a novel experimental approach to Bose-Einstein condensation by increasing the particle number of the system at almost constant temperature. In particular the emergence of a new condensate is observed in multi-component F=1 spinor condensates ...
