The development of noble metal free, robust catalyst is highly sought for commercialization of clean, renewable energy technology and to replace the fossil fuel‐based energy equipments. Herein, we report a highly efficient and stable ternary Nickel Iron oxide (NiFe2O4) electrocatalyst for bifunctional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in alkaline medium. The as‐synthesized NiFe2O4 has been confirmed by techniques like FESEM, HR‐TEM, powder X‐ray diffraction (XRD), and X‐ray photoelectron spectra analysis. NiFe2O4 demonstrate nanoparticle morphology with an average size of ∼10 nm. The synthesized NiFe2O4 electrocatalyst exhibit superior electrocatalytic efficiency for OER, and achieves a current density of 10 mA cm−2 at an overpotential of 290 mV, with smaller Tafel slope of 42 mV/dec. A stable performance of OER is obtained at 10 mA cm−2 for more than 8 h. The electrocatalytic activity of NiFe2O4 is comparable with benchmark electrocatalyst IrO2/C. Similarly, NiFe2O4 also shows superior HER activity in 1 M KOH. The enhanced bi‐functional activity of NiFe2O4 is thought to be the synergy between the multicomponent structure of NiFe2O4, high surface area, and stability leading to high electrical conductivity.

“…Dry magnetoliposomes (DMLs) are expected to have better magnetic response when compared with AMLs. 30,39,[54][55][56][57][58] Compared with the literature, our route stands out because coating of the magnetic NP cluster with the lipid bilayer occurs only after NP synthesis. 53 The new method for the synthesis of DMLs described here is a promising route to obtain liposomes with improved magnetic properties.…”

Nickel ferrite nanoparticles with superparamagnetic behavior at room temperature were synthesized using a coprecipitation method. These magnetic nanoparticles were either covered with a lipid bilayer, forming dry magnetic liposomes (DMLs), or entrapped in liposomes, originating aqueous magnetoliposomes (AMLs). A new and promising method for the synthesis of DMLs is described. The presence of the lipid bilayer in DMLs was confirmed by FRET (Förster Resonance Energy Transfer) measurements between the fluorescent-labeled lipids NBD-C12-HPC (NBD acting as a donor) included in the second lipid layer and rhodamine B-DOPE (acceptor) in the first lipid layer. An average donor-acceptor distance of 3 nm was estimated. Assays of the non-specific interactions of magnetoliposomes with biological membranes (modeled using giant unilamellar vesicles, GUVs) were performed. Membrane fusion between both aqueous and dry magnetoliposomes and GUVs was confirmed by FRET, which is an important result regarding applications of these systems both as hyperthermia agents and antitumor drug nanocarriers.

An efficient method was developed for the [2 + 3] cycloaddition of sodium azide with nitriles to afford 5‐substituted 1H‐tetrazoles using nanonickel ferrite (NiFe2O4) as an effective heterogeneous catalyst in dimethylformamide. The main advantages of this method are high yields, simple methodology and easy work‐up. The catalyst can be recovered and reused for several cycles with predictable activity.
