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.

Polyethylene Glycol Camouflaged Earthworm Hemoglobin [PDF]

PLOS ONE, 2017
Nearly 21 million components of blood and whole blood and transfused annually in the United States, while on average only 13.6 million units of blood are donated. As the demand for Red Blood Cells (RBCs) continues to increase due to the aging population, this deficit will be more significant. Despite decades of research to develop hemoglobin (Hb) based

Extraction of uricase from Candida utilis by applying polyethylene glycol (PEG)/ NH4)2SO4 aqueous two-phase system [PDF]

, 2012
The purification of uricase from Candida utilis was performed by applying aqueous two-phase system (ATPS). Based on polyethylene glycols (PEG)/(NH4)2SO4 ATPSs, purification fold and recovery rate were demonstrated to influence the system parameters, such

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

Advanced Functional Materials, EarlyView.
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

Dynamics of micrometer-scale phase separation in a polymer mixture upon laser irradiation [PDF]

arXiv, 2005
Ten $\mu$m -sized droplets in an aqueous-two-phase system (water/ polyethylene-glycol (PEG)/ dextran) dissapear upon irradiation with a focused YAG laser. The interface of the dextran-rich droplet broadens, indicating smoothing of the concentration profile, whereas, the PEG-rich droplet shrinks and disappears.
