Lithium-based batteries with improved safety performance are highly desired. At present, most hazard is the consequence of ignition and flammability organic liquid electrolytes. Dry ceramic-polymer composite electrolytes attractive for their merits non-flammability, reduced gas release, thermal stability, in addition to mechanical strength flexibility. We recently fabricated free-standing solid...

Poly(ethylene oxide) (PEO)-brushes are generally recognized as protein-repellent surfaces, and although a role in discouraging microbial adhesion has been established for some strains and species, no study exists on the effects of PEO-brushes on a large variety of bacterial and yeast strains. In this paper, a PEO-brush has been covalently attached to glass and silica by reaction in a polymer me...

Two-dimensional Nuclear Overhauser Enhancement SpectroscopY NMR has been applied to study sodiumdodecylsulfate (SDS)/polyethyleneoxide (PEO)/D2O at 10, 20, 25, and 40 ◦C. The results indicate that PEO interacts preferentially with the surface of the micelle aggregates at 20 and 25 ◦C, displacing some water molecules from the hydration sphere. At 40 ◦C the polymer tends to penetrate the interior...

Facile, one-step synthesis of self-assembling, cationic block copolymers of poly(2-N-(dimethylaminoethyl) methacrylate) (pDMAEMA) and PEO-PPO-PEO (Pluronic®) is developed. The copolymers are obtained via free-radical polymerization of DMAEMA initiated by Pluronic-radicals generated by cerium (IV). The copolymers possess surface activity, are polycationic at pH<7.1, and self-assemble into micell...

The effect of lignin nanoparticles (LNPs) on the crystallization kinetics poly(ethylene oxide) (PEO) is examined. Lignin from spruce and ionic isolation was used to prepare LNPs with a number-averaged diameter 85 nm (with relatively large polydispersity) by an ultrasonication method. PEO-based nanocomposites four different LNP contents (5, 10, 15, 20 wt %) were prepared subject isothermal nonis...

Aim of this study was to evaluate in patients with progressive external ophthalmoplegia (PEO) the left ventricular function by standard echocardiography and tissue Doppler imaging (TDI) analysis. Twenty patients with PEO (55.4 ± 17.5 years) and 20 ageand sex-matched healthy subjects underwent standard echocardiography with TDI analysis to assess left ventricular function. TDI was performed by p...
