A three-component process for the one-pot synthesis of 6-amino-4-aryl-5-cyano-3-methyl-1-phenyl-1,4-dihydropyrano[2,3-c]pyrazoles is described by the three-component reaction of aldehydes, 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one and malononitrile in the presence of Fe3O4@FSM-16-SO3H as an efficient magnetically recyclable mesoporous catalyst. Folded shee...

Abstract In this work, we investigate alternative materials systems that, based on their intrinsic magnetic properties, have the potential to deliver enhanced heating power in fluid hyperthermia. The focus lies with high magnetization phases, namely iron-nitrogen (Fe-N), iron-boron (Fe-B) and iron-carbon (Fe-C) compounds, performance comparison conventionally used iron oxides, γ -Fe 2 O 3 , Fe ...
