The present article describes experimental and theoretical investigations of miscibility and crystallization behavior of blends of poly(ethylene oxide) (PEO) and triacrylate monomer (TA) using differential scanning calorimetry and optical microscopy. The PEO/TA blends manifested a single T(g) varying systematically with composition suggestive of a miscible character in their amorphous states. M...

We have studied the rheological property evolution and hydration behavior of white and ordinary portland cement (type I) pastes and concentrated cement–polyelectrolyte suspensions. Cement composition had a marked effect on the elastic property evolution (G (t)) and hydration behavior of these suspensions in the presence of poly(acrylic acid)/poly(ethylene oxide) copolymer (PAA/PEO), even though...

Spontaneous liposome formation is predicted in binary mixtures of fluid phase phospholipids and poly(n)ethylene oxide (PEO)-bearing lipids by using single chain mean field theory. The range of stability of the spontaneous liposomes is determined as a function of percentage of PEO-conjugated lipids and polymer molecular weight. These predictions were tested by using cast films of 1, 2-diacyl-sn-...

BACKGROUND Progressive external ophthalmoplegia (PEO) is an eye movement disorder characterised by paresis of the extra ocular muscles and muscle restricted multiple mitochondrial DNA (mtDNA) deletions. Classification of patients is particularly difficult due to overlapping phenotypes and a poor genotype-phenotype relationship. Despite the identification of several nuclear encoded genes causing...

Poly(methoxy(polyethyleneoxy)propyl-co-methacryloxypropyl) silsesquioxane membranes with different copolymer ratios were successfully fabricated via UV-induced crosslinking with mechanical stability. By selectively introducing polyethylene oxide (PEO) groups covalently bound to the ladder-structured polysilsesquioxane, we effectively suppressed the PEO crystallization, allowing for excellent CO...

The effect of Polyethylene Oxide (PEO) with a molecular weight 10000g/mol on the rheological behavior bentonite suspension was examined in terms viscosity, yield stress and viscoelastic modulus (G’ G’’); characteristic complex behaviour montmorillonite water. A Physica MCR301 rheometer has been used to measure properties samples (6% bentonite) as well bentonite-PEO mixtures at different concent...

In the present paper, we report the synthesis of bimodal mesoporous anatase TiO2 films by the EISA (Evaporation-Induced Self-Assembly) method using sol-gel chemistry combining two porogen agents, a low molecular weight ionic template and a neutral block copolymer. The surfactant template (C16mimCl) generates non-oriented worm-like pores (8 to 10 nm) which connect the regularly packed ellipsoida...

Plasma electrolytic oxidation (PEO) is proven as a scalable method for surface treatment of titanium (Ti) providing thick oxide layer with porous micro-nano morphology. Despite the lack antibacterial performance, this modification has potential to improve osseointegration properties Ti-based implant. To address limitation, we demonstrated new concept, showing that partial incorporation graphene...
