Owing to its cost-effectiveness and adjustable eight-electron distribution in the 3d orbital, nickel oxide (NiO) is considered an effective electrocatalyst for ambient electrochemical nitrogen reduction reaction (NRR). However, because of low conductivity transition metal electrocatalyst, application this field limited. In study, we found that doping NiO nanosheets with a small amount (3–10 nm)...

We review the phenomenology of the exchange bias and its related effects in core-shell nanocrystals. The static and dynamic properties of the magnetization for ferromagnetic Ni-core and antiferromagnetic NiO-shell cluster glassy nanoparticles are examined, along with the pinning-depinning process, through the measurement of the conventional exchange bias, and associated with different cooling f...

In this study, a uniform nanoporous NiO film, with a thickness of up to 2.6 μm, was prepared using polyethylene glycol (PEG). The addition of PEG significantly decreased the cracks in the NiO film and prevented the peeling of the NiO film from a fluorine-doped tin oxide substrate. The NiO cathode was prepared using CdSeS quantum dots (QDs) as the sensitizer, with an optimized photoelectric conv...

the cu doped nio (nio:cu) nanoparticles were synthesized by co-precipitation method using nicl2.6h2o, cucl2.2h2o for ni and cu sources, respectively. sodium hydroxide has been used as a precipitator agent. effect of cu doping agent on the structural and optical properties of nanostructures were characterized by xrd, sem, afm, spectrophotometry, ftir and vsm techniques. xrd revealed that nio:cu ...

The bacterial-induced hollow cylinder NiO (HCNiO) nanomaterial was utilized for the enzymeless (without GOx) detection of glucose in basic conditions. The determination of glucose in 0.05 M NaOH solution with high sensitivity was performed using cyclic voltammetry (CV) and amperometry (i-t). The fundamental electrochemical parameters were analyzed and the obtained values of diffusion coefficien...
