Spatial Distribution of PEO–PPO–PEO Block Copolymer and PEO Homopolymer in Lipid Bilayers

open access: yesLangmuir, 2020
Maintaining the integrity of cell membranes is indispensable for cellular viability. Poloxamer 188 (P188), a poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymer with a number-average molecular weight of 8700 g/mol and containing 80% by mass PEO, protects cell membranes from various external injuries and ...

DPD Study on the Interfacial Properties of PEO/PEO-PPO-PEO/PPO Ternary Blends: Effects of Pluronic Structure and Concentration [PDF]

open access: yesPolymers, 2021
Using the method of dissipative particle dynamics (DPD) simulations, we investigated the interfacial properties of PEO/PEO-PPO-PEO/PPO ternary blends composed of the Pluronics L64(EO13PO30EO13), F68(EO76PO29EO76), F88(EO104PO39EO104), or F127(EO106PO70EO106) triblock copolymers. Our simulations show that: (i) The interfacial tensions (γ) of the ternary

Influence of Polyethylene Oxide (PEO) on the Performance of Chinese Lacquer Films

open access: yesBioResources, 2022
The Chinese lacquer composite films were prepared by modifying raw lacquer with polyethylene oxide. The film was characterized via Fourier-transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy. The infrared spectra

Successful myomectomy in early pregnancy for a large asymptomatic uterine myoma: case report

open access: yesThe Pan African Medical Journal, 2016
The decision of myomectomy is not usually taken by OBG specialist for uterine fibroids during pregnancy because of its complications which may become hazardous at times. This is why it is generally delayed until after delivery.

Body-shape trajectories and their genetic variance component in Gilthead seabream (Sparus aurata L.)

open access: yesScientific Reports, 2021
The phenotype of juvenile fish is closely associated with the adult phenotype, thus consisting an important quality trait for reared fish stocks. In this study, we estimated the correlation between the juvenile and adult body-shape in Gilthead seabream ...

Nanostructuring Biobased Epoxy Resin with PEO-PPO-PEO Block Copolymer

open access: yesPolymers, 2023
A biobased diglycidyl ether of vanillin (DGEVA) epoxy resin was nanostructured by poly(ethylene oxide-b-propylene oxide-b-ethylene oxide) (PEO-PPO-PEO) triblock copolymer. Due to the miscibility/immiscibility properties of the triblock copolymer in DGEVA resin, different morphologies were obtained depending on the triblock copolymer amount.
