Self-assembly of mixed surfactants sodium dodecylsulfate and polyethylene glycol dodecyl ether in aqueous solutions [PDF]
Journal of Molecular Liquids, 412 (2024) 125742The thermodynamic behavior of mixed systems containing the anionic surfactant sodium dodecyl sulfate (SDS) and the nonionic surfactant polyethylene glycol dodecyl ether (Brij L4) in aqueous solutions was investigated. Electrical conductivity and interfacial tension measurements were employed to investigate the concentration-dependent properties of ...

Polymer Induced Bundling of F-actin and the Depletion Force [PDF]
, 2003 The inert polymer polyethylene glycol (PEG) induces a "bundling" phenomenon in F-actin solutions when its concentration exceeds a critical onset value C_o. Over a limited range of PEG molecular weight and ionic strength, C_o can be expressed as a function of these two variables.

Osmotic pressure induced coupling between cooperativity and stability of a helix-coil transition [PDF]
PRL 109, 068101 (2012), 2012 Most helix-coil transition theories can be characterized by a set of three parameters: energetic, describing the (free) energy cost of forming a helical state in one repeating unit; entropic, accounting for the decrease of entropy due to the helical state formation; and geometric, indicating how many repeating units are affected by the formation of one

Elucidation of Conformational Hysteresis on a Giant DNA [PDF]
, 2007 The conformational behavior of a giant DNA mediated by condensing agents in the bulk solution has been investigated through experimental and theoretical approaches. Experimentally, a pronounced conformational hysteresis is observed for folding and unfolding processes, by increasing and decreasing the concentration of condensing agent PEG (Polyethylene ...

Biomimetic Spider Silk by Crosslinking and Functionalization with Multiarm Polyethylene Glycol
Advanced Functional Materials, Volume 35, Issue 15, April 10, 2025.Bioconjugation of recombinant mini‐spidroins with multiarm polyethylene glycol (PEG) is employed to produce artificial spider silk, which can be crosslinked and chemically functionalized while maintaining a biomimetic spinning approach. The best fibers exhibit enhanced tensile strength and/or extensibility, both contributing to an increased toughness ...

A temperature-dependent implicit-solvent model of polyethylene glycol in aqueous solution [PDF]
arXiv, 2017 A temperature (T)-dependent coarse-grained (CG) Hamiltonian of polyethylene glycol/oxide (PEG/PEO) in aqueous solution is reported to be used in implicit-solvent material models in a wide temperature (i.e., solvent quality) range. The T-dependent nonbonded CG interactions are derived from a combined "bottom-up" and "top-down" approach.

The compaction properties of polyethylene glycols
Journal of Pharmacy and Pharmacology, 1985 Abstract The mechanical properties of polyethylene glycol (PEG) powders of different average molecular weights have been characterized in terms of their yield pressure, determined from the densification of compacts by the method of Heckel. The yield pressure was found to be proportional to the molecular weight of the PEG.
