In this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. The benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (CH3COO)2Cu.H2O individually as Cu sources. Al...

BACKGROUND Ether phospholipids are abundant membrane constituents present in electrically active tissues (e.g., heart and the brain) that play important roles in cellular function. Alterations of ether phospholipid molecular species contents are associated with a number of genetic disorders and human diseases. METHODOLOGY/PRINCIPAL FINDINGS Herein, the power of shotgun lipidomics, in combinat...

Based on a global kinetics of direct dimethyl ether (DME) synthesis process from syngas, a steady-state one-dimensional mathematical model for the bubble column slurry reactor (BCSR) has been established. It was built on the assumption of plug flow of gas phase, sedimentation-dispersion model of catalyst grains and isothermal chamber regardless of reaction heats and rates for the design of an i...

We describe here the first example of an iterative convergent strategy for the synthesis of dendritically branched polymers involving condensation coupling reactions of AB2 macromonomers. The macromonomers were synthesized by living anionic polymerization, initiated with 3-tertbutyldimethylsiloxy-1-propyllithium and end capped with 1,1-bis(4-tert-butyldimethylsiloxyphenyl) ethylene. Following a...

Timothy Williamson’s Knowledge and its Limits is a treasure trove of philosophical riches. By reversing the usual explanatory order and putting “knowledge first” in epistemology (p. v) Williamson reconceives the relationships between knowledge, belief, justification and evidence. While there is much to be said about Williamson’s ambitious project, I will focus on his imaginative account of evid...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
