This paper proposes a new strategy for producing thin films of TiO2 with embedded gold nanoparticles (TiO2/AuNP). One the main tasks was synthesis stable dispersion and in an aqueous solution ethylene glycol, suitable inkjet printing—ink complex (AuCNP ink). The AuCNP were synthesized by reduction from tetrachloroauric acid presence glycol (EG). final formation TiO2/AuNP occurred during anneali...
Past studies on the toxicological effects of ethylene glycol alkyl ethers as well as the recent data on these chemicals in Japan are reviewed. Only a few researchers have participated in the study of ethylene glycol alkyl ethers in Japan. The effects of ethylene glycol alkyl ethers on testis and embryotoxic effects of ethylene glycol monomethyl ether (EGM) have been studied, as has the teratoge...
Ethylene glycol (EG) produced from biomass is a promising candidate for several new applications. In this paper, EG derivatives such as mono- and di-tert-butyl ethers are considered. However, accurate thermodynamic data essential to optimise the technology of direct tert-butyl ether synthesis reaction or reverse process isobutene release. The aim work measure vapour pressures combustion energie...
A strictly anaerobic, homoacetogenic bacterium was enriched and isolated from anoxic sewage sludge with polyethylene glycol (PEG) 1000 as sole source of carbon and energy, and was assigned to the genus Acetobacterium on the basis of morphological and physiological properties. The new isolate fermented ethylene glycol and PEG's with molecular masses of 106 to 1000 to acetate and small amounts of...
Comparison of Ethylene Glycol and Propylene Glycol for the Vitrification of Immature Porcine Oocytes
Our aim was to optimize a cryoprotectant treatment for vitrification of immature porcine cumulus-oocyte complexes (COCs). Immature COCs were vitrified either in 35% ethylene glycol (EG), 35% propylene glycol (PG) or a combination of 17.5% EG and 17.5% PG. After warming, the COCs were in vitro matured (IVM), and surviving oocytes were in vitro fertilized (IVF) and cultured. The mean survival rat...
In this paper, an experimental study has been conducted on the rheological behavior of Water (80%) and Ethylene-glycol (20%) in presence of Al2O3-MWCNTs hybrid nanomaterials. For this purpose, nanofluid samples were prepared by suspending the nanomaterials in a mixture of water and EG with solid volume fractions of 0.0625%, 0.125%, 0.25% and 0.5% Viscosity measurements were performed at various...
Strontium titanate (SrTiO3) thin films were prepared by dip-coating Si(111) single-crystal substrates in citrate solutions of ethylene glycol, considering several citric acid/ethylene glycol (CA/EG) ratios. Measurements of intrinsic viscosity indicate that increasing the amount of EG increases the precursors’ polymeric chains and increases the weight loss. After deposition the substrates were d...
Objective: Urolithiasis is one of the most painful ailments of the urinary tract disorders found in humans. The aim of the present study was to investigate the anti-urolithiatic activity of artichoke leaf extract (ART) on ethylene glycol (EG)induced urolithiasis in albino rats. Methods: urolithiasis was induced by adding ethylene glycol (0.75% v/v) to drinking water of rats for 28 consecutive d...
Abstract 1, 2‐Ethandiol (ethylene glycol, EG) and its mixtures with water (W) have widespread industrial biological applications due to their special physiochemical properties. In this study, two‐dimensional correlation spectroscopy chemometrics analysis of infrared spectra are used characterize structural features EG–W binary solutions. Three distinctive regions observed diverse contributions ...
pet wastes from post consumer bottles can be chemically degraded into some compounds such as oligomers and some monomers such as bishydroxy ethyl terephthalate(bhet)by some catalysts(zn, co, pb and mn acetates) in ethylene glycol at 189 oc under n2 atmospheric pressure. the compounds obtained in the chemical depolymerization can be used as plasticizers in paint, fibbers, rubbers and plastic ind...
