Synthesis of small and large scale dynamos
Using a closure model for the evolution of magnetic correlations, we uncover an interesting plausible saturated state of the smallscale fluctuation dynamo (SSD) and a novel anology between quantum mechanical tunneling and the generation of large-scale fields. Large scale fields develop via the α-effect, but as magnetic helicity can only change on a resistive timescale, the time it takes to orga...
متن کاملOne-pot synthesis of ferrocene-containing 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane (Ph3PNNC), cyclic ketones and ferrocene carboxylic acid
Reactions of N-isocyaniminotriphenylphosphorane with a cyclic ketone in the presence of ferrocene carboxylic acid proceeded smoothly at room temperature and in neutral conditions to afford ferrocene-containing 1,3,4-oxadiazole derivatives in high yields. The reaction proceeded smoothly and cleanly under mild conditions and no side reactions were observed. The structures of the products were ded...
متن کاملTreatment of small scale gold mining wastewater using pilot-scale sedimentation and Cocopeat filter bed system
The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...
متن کاملSynthesis and Thermal Properties of Some Ferrocene Containing Liquid Crystals
The synthesis and mesophase characterization of some monosubstituted ferrocene-containing liquid crystals were reported. For a better understanding of the thermal behavior, the LC properties were compared with a series of pattern compounds, possessing similar structures, but without the ferrocenyl unit. The liquid crystalline compounds without ferrocene group presented a very short stability of...
متن کاملSynthesis and characterization of new ferrocene peptide conjugates.
Three classes of diamine linked ferrocene (Fc)-conjugates were prepared and their properties were investigates in solution and the solid state: (a) acyclic diamine-linked 1,n'-Fc conjugates, (b) acyclic diamine-linked 1,n'-Fc peptide conjugates, and (c) cyclic 1,n'-Fc-peptide diamine conjugates. In all cases, the synthetic procedure started from 1,1'-ferrocenecarboxylic acid methyl ester or 1,1...
