Understanding the transport mechanism of Li+ in solid polymer electrolytes is beneficial for improving safety and energy density lithium-ion batteries. In this work, we investigate effects chain length poly (ethylene oxide) (PEO) anions (TfO-, TFSI-, PFSI-) on ion properties PEO-lithium salt systems using all-atom molecular dynamics simulations. We found that PEO monomers are co-diffusion, rega...

Recently, PEO process of tantalum has been developed as a method of producing corrosion-resistant, hard, wear-resistant, and biocompatible as well as having good adhesion coatings. In this review, we present the results of PEO process of tantalum in three main electrolytes. This review tries to measure the effect of electrolyte composition and voltage that were used within PEO procedure on the ...

Fourier transform infrared (FTIR) and scanning transmission X-ray microscopy (STXM) spectroscopic imaging techniques are introduced to determine the structure of protein-based polymer blends, using the silk fibroin/polyethylene oxide (SF/PEO) blend as a model material. We demonstrate that FTIR and STXM imaging techniques provide complementary chemical sensitivities, resolution ranges and sample...

Particulate carriers such as polymeric micelles (PMs) and liposomes have been investigated to increase drug accumulation in tumors and reduce distribution to healthy tissues. In this study, we prepared PM and hybrid nanoparticles (HNPs) with poly(ethylene oxide)-block-poly(methacrylic acid) (PEO-b-PMAA) for loading cisplatin, and evaluated cisplatin release, cytotoxicity, and biodistribution in...

Due to energy crises in the future, much effort is being directed towards alternate sources. Solar energy is accepted as a novel substitute for conventional sources of energy. Out of the long list of various types of solar cells available on the market, solid state photoelectrochemical solar cells (SSPECs) and dye sensitized solar cells (DSSCs) are proposed as an alternative to costly crystalli...

A influência da composição do eletrólito (ácido sulfúrico, ácido perclórico e suas misturas) sobre a cinética eletródica da reação de desprendimento de oxigênio (RDO) e a produção eletroquímica de ozônio (PEO) em eletrodo de β-PbO 2 , foi investigada empregando-se a espectroscopia de impedância eletroquímica e curvas de polarização quase-estacionárias. A análise dos espectros de impedância reve...

The throughput and efficiency of membrane separations make polymer filtration membranes an important resource for the pharmaceutical, food and wastewater treatment industries. Nanofiltration (NF) membranes fill an important niche between nonporous reverse osmosis membranes, which have comprehensive solute rejection and low solvent permeability, and porous sieving ultrafiltration membranes. Howe...

objective(s): to improve water stability of electrospun chitosan/ polyethylene oxide (peo) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  materials and methods: different amounts of genipin were added to the chitosan/peo solutions, chitosan/peo weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

The semisynthetic oripavine derivative phenethyl orvinol (PEO), a full agonist at opioid receptors (OR), is an attractive structural motif for developing ¹⁸F-labeled PET tracers with a high degree of sensitivity for competition between endogenous and exogenous OR-ligands. The target cold reference compound 6-O-(2-fluoroethyl)-6-O-desmethylphenylethyl orvinol (FE-PEO) was obtained via two separa...
