In this study, the zinc containing dust and sludge of iron steel smelting was taken as research object, new ionic liquid choline-urea prepared synthesized leaching agent. The conventional ultrasonic were compared, influence liquid-solid ratio, temperature, time, power other conditions on rate analyzed. residue characterized by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (...

Abstract. In spite of resin recycling carbon fiber reinforced plastics (CFRP) is very important as well-known on the viewpoint environmental protection and resource conservation, development effective had hardly been investigated. this study, we investigated operating conditions for microwave decomposition CFRP using various alcohols solvents. order to avoid rapid absorption microwaves into fib...

objective(s): this study aimed to compare the diagnostic values of 11c-choline and 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography/computed tomography (pet/ct) in patients with cholangiocarcinoma (cca). methods: this prospective study was conducted on 10 patients (6 males and 4 females), aged 42-69 years, suspected of having cca based on ct or magnetic resonance imaging (mri) resu...

Deep Eutectic Solvents (DES) are ionic liquid analogs that have attracted considerable attention as green solvents for biocatalytic transformations. The use of DES part a ‘solvent engineering’ approach to enhance enzyme stability holds great promise since they biodegradable, relatively inexpensive and environmentally safe media reactions. However, the behaviour specific enzymes in such is compl...

Micromethods for the determination of choline have been described by Beattie (1936) and Glick (1944). Both procedures involved the use of Reinecke salt as a precipitant, required 20150 pmoles of choline and depended on measurement of the pink colour of an acetone solution of the precipitate. More sensitive modifications of the reineckate method depend upon measurement of the chromium content of...

Despite the known adverse consequences of prenatal alcohol exposure, some pregnant women continue to drink alcohol, making it imperative to identify treatments for children with fetal alcohol spectrum disorders. The authors recently reported that perinatal choline supplementation can reduce some fetal alcohol effects (J. D. Thomas, M. Garrison, & T. M. O'Neill, 2004), and the present study exam...
