-A stable 8.4/~ hydrate of kaolinite was prepared by exchanging ethylene glycol for water in the 10.8 A intercalate of ethylene glycol in kaolinite. The hydrate of kaolinite was characterized by XRD, FTIR and TGA/DSC. From the TGA data, one can estimate that there is 0.60 water molecule per A12Si20~(OH)4 units. The IR data suggest a similarity of the local environment of the intercalated water ...

From a regression analysis perspective, this paper focused on literature about TiO2 nano particles. The particles on focus entailed those that had been suspended in ethylene glycol and water – at a ratio of 60:40. Indeed, regression analysis has gained application in contexts such as the turbulent Reynolds number, especially with the aim of establishing the impact of the ratio of the...

Is the recently found seepage groundwater on Mars pure H2O, or mixed with salts and other antifreeze compounds? Given the surface conditions of Mars, it is unlikely that pure water could either exist in its liquid state or have shaped Mars’ fluid erosional landforms (gullies, channels, and valley networks). More likely is that Mars’ seepage groundwater contains antifreeze and salt compounds tha...

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 d...

Polymers containing poly(ethylene glycol) methacrylate and 2-(2-methoxyethoxy)ethyl methacrylate have been synthesized by Cu(0)-mediated radical polymerisation for use as thermoresponsive water-dispersants for carbon nanotubes.

The oxidation of ethylene glycol by periodate (IO4 (-)) was studied in different micellar aggregates of cetyltrimethylammonium bromide (CTABr) and dodecylamine (DA) by means of UV/Vis spectroscopy. The observed constant K o was obtained by monitoring the disappearing of ethylene glycol with time at a suitable wavelength under pseudofirst condition. Addition of CTABr and DA inhibits the reaction...

The affinity of protein surface amino acids for poly(ethylene glycol)(PEG)(reported by the PEG/water ratio in their vicinity) is used to build a quantitative model of protein adsorption on PEGylated nanoparticles.

The present work evaluates the performance of solar collector using Al2O3-C2H6O2-H2O nanofluid as a working fluid through both experimental and CFD analysis. Ethylene-glycol water mixture (40:60 v/v) is used as base fluid, where α-Al2O3 nanoparticle of 20 nm average size is dispersed for the preparation of nanofluid of four different volumetric concentration (vol. conc.) of 0.05, 0.075, 0.1 and...
