Ethylene glycol is a colorless, odorless, sweet-tasting but poisonous type of alcohol found in many household products. The major use of ethylene glycol is as an antifreeze in, for example, automobiles, in air conditioning systems, in de-icing fluid for windshields, and else. People sometimes drink ethylene glycol mistakenly or on purpose as a substitute for alcohol. Ethylene glycol is toxic, a...

This work aims to establish comparisons between two models used for the performance of heat exchangers. The chosen system, in this case, consists a exchanger automotive radiators flat finned tube type. Water and ethylene glycol compound as base fluid volume fractions iron oxide nanoparticles (Fe3O4) are refrigerant. quantities determined nanofluid exit temperature, air absolute error transfer r...

ABSTRACT New alternating fluorene-thiophene copolymers are introduced bearing polar ethylene glycol-carboxylate functionalities on the thiophene ring to achieve enhanced solubility in polar solvents. Suzuki polycondensation was applied to synthesize a set of three polymers with differing lengths of the ethylene glycol side-chains. The polymers are thermally stable up to temperatures of 300 °C. ...

The performance of ONIOM(DFT:MM) methods on the structural description of molecules where intramolecular non-covalent interactions play a critical role is examined systematically and compared with that of full DFT methods, both with and without explicit dispersion corrections. The more detailed study is carried out on dithienobicyclo-[4.4.1]-undeca-3,8-diene-11-one ethylene glycol ketal molecul...

Smart biomaterials composed of pH responsive polymers, poly((meth)acrylic acid), were synthesized using a precipitation polymerization technique. The microparticles were grafted with poly(ethylene glycol) (PEG) chains that are capable of complexing with the hydroxyl groups of the polyacid and interpenetrating into the mucus gel layer upon entry into the small intestine. Upon introduction of an ...

In this communication, EuTe nanoparticles with different size distributions have been synthesized for the first time at room temperature by injection of ethylene glycol solution of Na2Te into ethylene glycol solution of EuCl2 in the presence of triethanolamine. By adding phenanthroline into EuCl2 solution, EuTe nanospindles have also been synthesized. The as-synthesized EuTe nanocrystals show s...

Dual beam thermal lens technique is successfully employed for the determination of absolute fluorescence quantum yield of rhodamine 6G laser dye in different solvents. A 532 nm radiation from a Q-switched Nd:YAG laser was used for the excitation purpose. The fluorescence quantum yield values are found to be strongly influenced by environmental effects. It has been observed that fluorescence yie...

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. group i served as positive control and received distil...

This paper presents a new optofluidic method to measure the mutual diffusion coefficient in binary solutions by directly analyzing the diffusion-induced focusing pattern based on a single optical micrograph. The average diffusion coefficient of ethylene glycol (EG) and deionized water binary solution is measured under different mass fractions and flow rates to demonstrate the proposed method. E...

The contractility of the frog sartorius muscle was suppressed after treatment with a Ringer solution added with ethylene glycol (EGR). No contraction was elicited by nerve stimulation when the muscle was brought back to normal Ringer solution after having been soaked in 876 mM EGR for 4 hr or in 1095 mM EGR for 2 hr. However, the action potential of normal amplitude was generated and followed b...
