Cryogenic Viscoelasticity of a C22–Tailed Amine Oxide across an Extremely Broad pH Range

Qiang Chen, Wei Xu, Lulu Liu, Hongyao Yin et autres

Sustaining viscoelasticity of surfactant solutions at subzero temperatures and across extreme pH regimes remains challenging, as freezing and harsh acidic or alkaline environments inhibit aggregate growth and retard structural relaxation. This study examines microstructural evolution and rheological response of C22-tailed amine oxide …

A high-temperature and high-pressure optical cell for oil–water separation with porous materials

Gang Zhu, Hao Chen, Yan Zhang, Xuezhi Zhao et autres

Some industrial oil-water separations require in situ separation under high-temperature and high-pressure (HTHP) conditions. Although porous materials are promising for this purpose, dedicated optical cells capable of evaluating their separation performance under controlled HTHP environments remain scarce. Here, an HTHP optical cell …

Effect of Inorganic Counterions on the Self-Assembly Behavior and Rheological Properties of Ultralong-Chain Cationic Surfactant

Ruibo Cao, Hongyao Yin, Yanfu Pi, Bo Li et autres

Ultralong-chain quaternary ammonium surfactants serve as promising clean fracturing-fluid thickeners owing to their facile formation of wormlike micelles (WLMs) in salt solution. However, the ion-specific effects of common inorganic counterions on the formation of WLMs still remain unclear. In this study, we …

Quantifying the Thickening Power of High-Molecular-Weight Thermoviscosifying Polymers in Pure Water

Shiwei Li, Hongyao Yin, Qian Huang, James Doutch et autres

Thermoviscosifying polymers (TVPs), which thicken aqueous solutions upon heating, deviate from the conventional thermothinning behavior and hold promise as effective rheology modifiers under harsh conditions. However, their thickening efficiency at low concentrations remains limited by relatively low molecular weights, and the quantitative …

Transient Receptor Potential Channels as Key Regulators of Neuroinflammation in Neurological Disorders: Mechanistic Insights, Therapeutic Potentials, and Future Directions

Daji Guo, Yinyin Chen, Yujun Feng, Chun Hu et autres

BACKGROUND: Transient receptor potential (TRP) ion channels, a ubiquitous family of nonselective cation channels, are extensively expressed across the nervous system, immune system, and peripheral tissues. These channels serve as critical sensors for detecting temperature, mechanical forces, and chemical stimuli, thereby regulating …

Quantifying the Dependence of Molecular Weight on Intrinsic Viscosity for Acrylamide and 2-Acrylamido-2-methylpropanesulfonate (Co)polymers

Shaowen Li, Xiao-Qin Cao, Yujun Feng, Hongyao Yin

Acrylamide–2-acrylamido-2-methylpropanesulfonate (AM–AMPS) copolymers are important water-soluble polymers widely used across diverse industries. The molecular weight plays a crucial role in determining the characteristics of their aqueous solutions, thereby directly affecting their performances in applications. However, the rapid and accurate determination of their …
