Sticker Valence Governs Chain Collapse and Liquid-Liquid Phase Separation in Peptide-Inspired Associative Polymers. [PDF]
Adv Sci (Weinh)Peptide‐inspired associative polymers with arginine‐like guanidinium stickers and lysine‐like ammonium spacers undergo chain collapse and liquid‐liquid phase separation induced by reversible sticker associations. Sticker valence and tunable association strength jointly control the phase behavior, chain conformation, and interfacial cohesion of these ...

Gaseous density calculation by means of relative permittivity measurement
Measurement: Sensors, 2021 This study presents a gaseous density calculation method on the basis of relative permittivity measurement. The relative permittivity of a gas sample is measured by using a cylindrical microwave cavity resonator in wide temperature and pressure ranges ...

A new simplified virial equation of state for high temperature and high pressure gas
AIP Advances, 2022 In this paper, in order to accurately describe the high temperature and high pressure state of gas under detonation conditions, a new simplified form of the virial equation of state (EOS)—the Virial–Peng–Long (VPL) EOS—is proposed based on the ...

Chemical Thermodynamics and Thermal Analysis, 2021 The old concepts of the Van der Waals equation (vdW EOS) and of the virial equation, truncated to the second virial coefficient, can be rewritten with a function defined as cc=(p−R·T/M)/ρ2. This function arises from introducing the ideal gas law into the

Virial Approximation for Load and Loss in High-Speed Journal Bearings Using Pressurized Gases
Fluids, 2019 We consider steady, laminar, compressible lubrication flows in a high-speed two-dimensional journal bearing governed by the appropriate Reynolds equation. The thermodynamic states correspond to pressurized gases and are in the single-phase regime. Simple
