Microbial Degradation of Polyethylene Glycols [PDF]
Journal of Applied Bacteriology, 1979 Three bacterial strains have been isolated that differ in their ability to degrade polyethylene glycols (PEGs). Strains R and O showed a marked preference for growth on the low and high molecular weight PEGs, respectively, while strain Z utilized mono‐ethylene glycol only. The partial degradation of PEG 200 by strains R and O was studied in some detail

Heat Transfer in Gold Interfaces Capped with Thiolated Polyethylene Glycol: A Molecular Dynamics Study [PDF]
J. Phys. Chem. B 2023, 127, 47, 10215-10225, 2023 Reverse non-equilibrium molecular dynamics (RNEMD) simulations were used to study heat transport in solvated gold interfaces which have been functionalized with a low molecular weight thiolated polyethylene glycol (PEG). The gold interfaces studied included (111), (110), and (100) facets, as well as spherical nanoparticles with radii of 10 and 20 {\AA}.

Liquid Transfer for Viscoelastic Solutions [PDF]
Langmuir, 37, 34, 10348-10353 (2021), 2021 Viscoelastic liquid transfer from one surface to another is a process that finds applications in many technologies, primarily in printing. Here, cylindrical shaped capillary bridges pinned between two parallel disks are considered. Specifically, the effects of polymer mass fraction, solution viscosity, disk diameter, initial aspect ratio, final aspect ...

Microbial Degradation of Polyethylene Glycols [PDF]
Applied Microbiology, 1975 Mono-, di-, tri-, and tetraethylene glycols and polyethylene glycols (PEG) with molecular weight up to 20,000 were degraded by soil microorganisms. A strain of Pseudomonas aeruginosa able to use a PEG of average molecular weight 20,000 was isolated from soil. Washed cells oxidized mono and tetraethylene glycols, but

Thermoelectric ratchet effect for charge carriers with hopping dynamics [PDF]
Phys. Rev. Lett. 126, 068001 (2021), 2020 We show that the huge Seebeck coefficients observed recently for ionic conductors, arise from a ratchet effect where activated jumps between neighbor sites are rectified by a temperature gradient, thus driving mobile ions towards the cold. For complex systems with mobile molecules like water or polyethylene glycol, there is an even more efficient ...

Polyethylene glycol as a cause of anaphylaxis [PDF]
Allergy, Asthma & Clinical Immunology, 2016 BACKGROUND: Polyethylene glycols (PEGs) or macrogols are polyether compounds and are widely used as additives in pharmaceuticals, cosmetics, and food. CASE REPORT: We report on a Caucasian patient experiencing recurrent severe allergic reactions to several drugs.

Structure and dynamics of motor-driven microtubule bundles [PDF]
arXiv, 2022 Connecting the large-scale emergent behaviors of active materials to the microscopic properties of their constituents is a challenge due to a lack of data on the multiscale dynamics and structure of such systems. We approach this problem by studying the impact of polyethylene glycol, a crowding agent, on bundles of microtubules and kinesin-14 molecular

Generation of silicone poly-HIPES with controlled pore sizes via reactive emulsion stabilization [PDF]
Macromolecular Rapid Communications 37,18 (2016): 1527-1532, 2016 Macrocellular silicone polymers are obtained after solidification of the continuous phase of a PDMS (polydimethylsiloxane) emulsion, which contains PEG (polyethylene glycol) drops of sub-millimetric dimensions. Coalescence of the liquid template emulsion is prohibited by a reactive blending approach.

Bacterial oxidation of polyethylene glycol [PDF]
Applied and Environmental Microbiology, 1978 The metabolism of polyethylene glycol (PEG) was investigated with a synergistic, mixed culture of Flavobacterium and Pseudomonas species, which are individually unable to utilize PEGs. The PEG dehydrogenase linked with 2,6-dichlorophenolindophenol was found in the particulate fraction of sonic extracts and catalyzed the formation of a 2,4 ...

What is the origin of chirality in the cholesteric phase of virus suspensions ? [PDF]
Phys. Rev. Lett. 90.198302. 2003, 2003 We report a study of the cholesteric phase in monodisperse suspensions of the rod-like virus fd sterically stabilized with the polymer polyethylene glycol (PEG). After coating the virus with neutral polymers, the phase diagram and nematic order parameter of the fd-PEG system then become independent of ionic strength.
