Research ArticleOpen accessPhrase in the titleRETRACTED: Toxicity Assessment of Phosphonium Based Ionic Liquids Towards Female Guppy FishMohanad El-Harbawi, Yasmin Syazwani Bt. Yusri, M. Ismail HossainIn this study, two phosphonium based ionic liquids (butyl triphenyl phosphonium chloride and hexyl triphenyl phosphonium bromide) have been synthesized using quarternisation process. The toxicities of these Ionic Liquids (ILs) are unknown and may be harmful to humans and the environment. Therefore, the toxicity assessment of these ILs was carried out according to the Organization for Economic Cooperation and Development … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 20 Jan 2014 · 6,851 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleThe Application of Ionic Liquids in Catholic Coupling of AcetophenonePo-Chung ChengProblem statement: The cathodic coupling of acetophnone was carried out in aqueous solutions containing sodium sulfate and 1-Octyl-3-Methylimidazolium Chloride ([OMIM]Cl) as supporting electrolytes. [OMIM]Cl is an ionic liquid, also serving as a co-solvent to prevent the deposition of products during electrolysis. The products are extracted with ether after electrolyses. Approach: It is shown in this study that the recycling of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,039 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleSeparation of Guanine and Hypoxanthine with Some Ionic Liquids in RP-HPLCJ. Zheng, K. H. RowIn this paper, guanine and hypoxanthine were separated with four different ionic liquids as additives for the mobile phase using reversed phase high performance liquid chromatography (RP-HPLC). The ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIm][BF4]), 1-ethyl-3-methylimidazolium methylsulfate ([EMIm][MS]) and 1-octyl-3-methylimidazolium methylsulfate ([OMIm][MS]) were used. Guanine and hypoxanthine couldn’t be separated with many different kinds of unadjusted mobile phase, such … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,892 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSimulation of Production of Anhydrous Bioethanol using Glycerol and 1-Butyl-3-Methylimidazolyl-Tetrafluoroborate in the Aspen Plus SimulatorJosé Izaquiel Santos da Silva, Lílian da Silva Félix, Mariana Martins Vieira et al.Biofuels are present in the global scenario as an energy source derived from organic biomass, representing an economic and environmental alternative. They are a renewable source of energy with low rates of pollutants emissions and, consequently, less carbon dioxide is released into the atmosphere. The obtaining of bioethanol is originated from a fermentation process, in which a multi-component mix is … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 16 Jun 2021 · 7,109 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMolecular Dynamics Simulation and Analysis of Crystallization System in PVC Tunnel Drain-Pipe at Different TemperaturesZhongwei Hou, Xuefu Zhang, Yuanjiang ZhouAiming at the problem that carbonate and calcium ions are easy to crystallize and precipitate in the drain-pipes of limestone tunnels and then adsorb on PVC pipes in Western China, a "solid-liquid interface model" for the interaction between PVC materials and ions in aqueous solution is established by using the molecular dynamics simulation software materials studio and the microscopic mechanism … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 9 Mar 2021 · 6,279 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSome Aspects of the Structure of Planar MechanismsRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The machine is a technical system made up of distinct kinematic component parts (called kinematic elements) which, following the imprinting of movements imposed on an element or elements (considered as leading elements), cause movements to all other kinematic elements in order to execute a useful mechanical thing, or transforming some form of energy into mechanical energy. It follows from the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Feb 2018 · 8,020 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,978 accessesView PDF Cite
