Structural and magnetic properties of Ni1-xZnxFe 2O4 (x=0, 0.5 and 1) nanopowders prepared by sol-gel method
Published 2013“…As the grain size increased, the Curie temperature of NiFe 2O4 increased from 849 to 859 K. The highest saturation magnetization of 70 emu/g at 298 K and the highest specific heating rate of 1.6 K/s under radiofrequency heating at 295 kHz were observed over NiFe 2O4 calcined at 1073 K. …”

Ferroelectric Properties and Electrocaloric Effect in Dy2O3 Substitution on Lead-Free (Na0.5 Bi0.5)0.94 Ba0.06TiO3 Ceramic
Published 2023“…Higher stability of the ferroelectric (FE) phase was obtained at room temperature for the compositions y = 0.01, 0.02 and 0.05, with optimum values for y = 0.02 as remanent polarization Pr = 32µC/cm2, as well as piezoelectric coefficients d33 = 137 pC/N, kp = 0.27 and kt = 0.16, whereas a higher content of Dy (y = 0.08) induced a remarkable decrease of the ferroelectric and piezoelectric properties. …”

Fabrication of Selective Sensors for Hg2+ Traces in Water Using Graphene Decorated with Metal Nanoclusters
Published 2016“…The selectivity was tested using 0.6 ppb solutions of the following ions: Cr2+, Cd2+, Cu2+, Co2+, Fe2+, Zn2+, and K+. The selectivity results of the sensor reveal that the fabricated sensors are selective to Hg2+ ions, and the selectivity is evidently enhanced for sensors with Au nanoclusters. …”

Evaluation of the inhibition performance of piperazine-based polyurea towards mild steel corrosion: The role of keto-enol tautomerization
Published 2022“…The inhibitor exhibits a sufficient protection of the surface of mild steel via an intra-molecular keto-enol proton transfer mechanism leading to the formation of the Fe-PUCorr complex. First-principles calculations proposed that the keto-enol tautomerism enhances the adsorption with an increase of adsorption energies of 510, 221, 171 and 211 kJ/mol on {100}, {110}, {111} and {112} surfaces of iron, respectively. …”

Hydropriming with moringa leaf extract mitigates salt stress in wheat seedlings
Published 2021“…The germination percentage was observed 10% more at 0.2 M NaCl stress in seeds treated with moringa leaf extract than seeds treated with water. The nutrient (K, Ca, Mg, P, S, Fe, B, Mn, Zn, Cu) uptake was also observed more in the shoots and roots of wheat seedlings soaked in moringa leaf extract as compared to soaked in water. …”
