new forms of vanadium oxide nanoporous were fabricated using a simple chemical synthesis method. vanadium pentoxide (v2o5) nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. the samples were characterized by high resolution transmission electron microscopy (hrtem), field effect scanning electron microscopy (fesem) and x-ray diffraction (xrd), four...

in this paper, the measurement of the viscosity of zno in ethylene glycol, propylene glycol, mixture of ethylene glycol and water (60:40 by weight), and a mixture of propylene glycol and water (60:40 by weight) and the thermal conductivity in ethylene glycol and propylene glycol as base fluids in the range of temperature from 25 ºc to 60 ºc are investigated. the results indicate that as the tem...

Ethylene glycol (HOCH2CH2OH), used as engine coolant for most on-road vehicles, is an intermediate volatility organic compound (IVOC) with a high Henry's law coefficient. We present measurements of ethylene glycol (EG) vapor in the Caldecott Tunnel near San Francisco, using a proton transfer reaction mass spectrometer (PTR-MS). Ethylene glycol was detected at mass-to-charge ratio 45, usually in...

Materials: Tetraethylorthosilicate (TEOS, 98%), aqueous ammonia (28%) were purchased from Sinopharm Chemical Reagent Co. Ltd.. Carbon black (99.5%, 30 nm) was purchased from Aladdin Co. Ltd.. Ethylene glycol (EG, 99%) and ethanol (99.9%) were purchased from J&K Co. Ltd.. Poly(ethylene glycol) methacrylate (PEGMA, Mn=360) and poly(ethylene glycol) diacrylate (PEGDA, Mn=700) was purchased from Si...

Marrow-derived osteoblasts were cultured on poly(propylene fumarate-co-ethylene glycol) (P(PF-co-EG)) based hydrogels modified in bulk with a covalently linked RGDS model peptide. A poly(ethylene glycol) spacer arm was utilized to covalently link the peptide to the hydrogel. Three P(PF-co-EG) block copolymers were synthesized with varying poly(ethylene glycol) block lengths relative to poly(eth...

Background & Aim: Punica granatum L. (pomegranate) is a widely used plant that has high nutritional value .This study evaluated prevention effect of hydro alcoholic extract of Punica granatum flower and leaves ethylene glycol-induced Nephrolithiasis in Wistar rats. Experimental: 20 male Wistar rats were randomly divided into 4 equal groups. G...

Background & Aim: This study evaluated prevention effect of hydro-alcoholic extract of punica granatum Peel ethylene glycol-induced Nephrolithiasis in wistar rats. Experimental: 20 male Wistar rats were randomly divided into 4 equal groups. Group I animals served as normal control (A) and received distilled water for 28 days. Group II to IV animals received 1% v/v ethylene glycol (EG) in disti...
