Solvents-Dependent Formation of Three MOFs from …

2019-12-21 · On the basis of the [Fe3(μ3-O)(COO)6] cluster and 3,3′,5,5′-diphenyltetracarboxylic acid (H4BPTC), three novel metal–organic frameworks (MOFs), NJU-Bai25, NJU-Bai26, and NJU-Bai27 (NJU-Bai for Bai’s group at Nanjing University ) with different (4,4,4,6)-, (4,4,4,4,4,6)-, and (4,4,6)-connected nets were obtained in different solvent systems, in which due to the steric hindrance of the ...

Magnetic relaxation in basic iron(iii) carboxylate [Fe3O ...

The magnetic properties of the antiferromagnetic basic iron(iii) carboxylate [Fe3O(O2CPh)6(H2O)3]ClO4·py are studied by magnetic susceptometry and electron paramagnetic resonance spectrocopy. Ac susceptometry under moderate external magnetic fields reveals magnetic relaxation at liquid helium temperatures.

Preparation and characterization of magnetic Fe3O 4 ...

A novel approach to synthesize core-shell nanoparticles with Fe 3O4 as the magnetic core and PPY as the conducting shell was investigated. The Fe3O4 nanoparticles primarily prepared by precipitation-oxidation method, and the Fe3O 4-PPY nanoparticles with core-shell structure was synthesized via an in-situ polymerization of pyrrole monomer in an aqueous solution containing well-dispersed Fe3O4 ...

Preparation and characterization of bio-compatible …

2011-8-15 · Bio-compatible and superparamagnetic Fe 3 O 4 @Polydopamine nanocomposites with well-defined core/shell nanostructures have been successfully synthesized by using an in situ self-polymerization method. The size of the core/shell product can be controlled by varying the size of the central Fe 3 O 4 core, and different thicknesses of the PDA shells are obtained by tuning the …
