The influence of surfactant structure on the dyeing of polyamide knitting with acid dyes [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2018
The influence of nonionic and anionic surfactants on the dyeing kinetics of polyamide 6 knitting was studied in this work. The influence of surfactants on the dyeing process is presented by determining the kinetic and thermodynamic parameters of dyeing ...

Study to improve an amphoteric sulfonate alkyl ester surfactant by mixing with nonionic surfactant to reduce brine–waxy oil interfacial tension and to increase oil recovery in sandstone reservoir: T-KS field, Indonesia

Journal of Petroleum Exploration and Production Technology, 2018
Crude oil with a high wax content and high pour point can be very challenging when enhanced oil recovery by surfactant flooding is to be applied. High wax content in crude oil will lead to high intermolecular interaction because of the increasing ...

Study on the effect of NMR-based surfactants on pore wetting of high-order coal

Meitan kexue jishu, 2023
High-order coal has the characteristics of weak water absorption due to the development of micropores. From the perspective of micropores, it is of great significance to study the improvement effect of different types of surfactants on the wettability of

Effects of nanoparticle composite surfactants on the adsorption/desorption and diffusion of CH4 in coal

Meitan xuebao, 2023
A solid (coal) - gas (CH4) - liquid (surfactant) three-phase interaction system model is established based on the Grand Canonical Monte Carlo (GCMC) and Molecular Dynamics (MD) methods.

Nonionic polymer surfactants [PDF]

Journal of Polymer Science: Polymer Chemistry Edition, 1982
AbstractNonionic water‐soluble polymeric surfactants have been prepared by addition of long‐chain n‐alkyl epoxides to nonionic cellulose ethers. The polymers exhibit properties which can be explained by interchain association. The relationship between hydrocarbon‐modifier carbon number and the onset of association follows a linear relation analogous to

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Influence of Added Surfactants on the Rheology and Surface Activity of Polymer Solutions

ChemEngineering
Steady-shear rheology and surface activity of surfactant–polymer solutions were investigated experimentally. Four different polymers were studied as follows: cationic hydroxyethyl cellulose, nonionic hydroxyethyl cellulose, nonionic guar gum, and anionic

The skills required for transition to university and study in biological sciences: A student perspective

FEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

A Normalized HLD (HLD_N) Tool for Optimal Salt-Concentration Prediction of Microemulsions

Applied Sciences, 2021
Optimal condition-based microemulsion is key to achieving great efficiency in oil removal. One useful empirical equation to predict an optimal condition is a hydrophilic–lipophilic deviation (HLD).
