Abstract: We present a simple preparation route to obtain a nanoscale metastable hard-magnetic ε-Fe2O3 phase, using silica coated β-FeOOH nanorods as a precursor and an annealing process. The synthesized ε-Fe2O3 nanoparticles exhibit large coercivity (HC ∼… read more here.

Abstract: Magnetic α-Fe2O3/Fe3O4 heterostructure nanosheets were fabricated via hydrothermal calcination. The activity of penicillin G acylase (PGA), which was covalently immobilized onto silica-decorated heterostructure nanosheets, achieved the highest activity of 387.03 IU/g after 18 h of… read more here.
