Rheological non-Newtonian behaviour of ethylene glycol-based Fe2O3 nanofluids
The rheological behaviour of ethylene glycol-based nanofluids containing hexagonal scalenohedral-shaped α-Fe2O3 (hematite) nanoparticles at 303.15 K and particle weight concentrations up to 25% has been carried out using a cone-plate Physica MCR rheometer. The tests performed show that the studied nanofluids present non-Newtonian shear-thinning behaviour. In addition, the viscosity at a given s...
متن کاملpropylene glycol , and ethylene glycol - based antifreeze
of AF performance. that contain EG has been reponed to result in irreversible damage to renal, hepatic, cardiovascular, and central nervous systems, and is a cause of death in household pets and other animals.2-4 It is not known why some animals ingest EGcontaining products. Although there are reports suggesting that the "sweet" taste of EG, and of products containing it, may lead to ingestion ...
متن کاملViscosity and Rheological Behavior of Ethylene Glycol-Maghemite Nanofluids
This work is devoted on the rheological behavior of ethylene glycol based nanofluids containing maghemtite nanoparticles. The size of these maghemite nanoparticles was measured using XRD and found to be about <50 nm. Major factors that influence on viscosity and rheological behavior, such as, temperature and particle mass concentration, were investigated over 25–80°C and 0.2 and 2% respectivel...
متن کاملPulmonary absorption and elimination of ethylene glycol monoethyl ether acetate in man.
Ten male volunteers were exposed to ethylene glycol monoethyl ether acetate (EGEE-Ac) under various conditions of exposure and physical workload. As exposure proceeded, retention, atmospheric clearance, and uptake rate declined slowly to reach steady state levels after three to four hours. Retention increased as a consequence of higher exposure concentrations and of physical workload performed ...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
