TiO2 (0–10 wt %)-doped nanocrystalline Ni0.4Cu0.3Zn0.3Fe2O4 (Ni–Cu–Zn) ferrites were synthesized using the sol–gel route of synthesis. The cubic spinel structure of the ferrites having the Fd3m space group was revealed from the analysis of Rietveld refined X-ray diffraction (XRD) data. The secondary phase of TiO2 with a space group of I41/amd was observed within the ferrites with doping, x > 3 wt %. The values of lattice parameter were enhanced with the addition of TiO2 up to 5 wt % and reduced further for the highest experimental doping of 10 wt %. Field emission scanning electron microscopy (FESEM) images exhibit the spherical shape of the synthesized particles with some agglomeration, while the compositional purity of prepared ferrite samples was confirmed by energy-dispersive X-ray spectroscopy (EDX) and elemental mapping. The cubic spinel structure of the prepared ferrite sample was confirmed by the Raman and Fourier transform infrared (FTIR) spectra. UV–visible diffuse reflectance spectroscopy was utilized to study the optical properties of the ferrites. The value of band gap energy for the pristine sample was less than those of the doped samples, and there was a decrement in band gap energy values with an increase in TiO2 doping, which specifies the semiconducting nature of prepared ferrite samples. A magnetic study performed by means of a vibrating sample magnetometer (VSM) demonstrates that the values of saturation magnetization of the ferrites decrease with the addition of TiO2 content, and all investigated ferrites show the characteristics of soft magnetic materials at room temperature. The Mössbauer study confirms the decrease in the magnetic behavior of the doped ferrites due to the nonmagnetic secondary phase of TiO2.

The organic and eco-friendly materials are extended to prevail over the worldwide energy crisis where bio-inspired carbonaceous electrode materials are being prepared from biogenic items and wastes. Here, coconut water is sprayed over three-dimensional (3D) nickel foam for obtaining a carbonaceous electrode material, i.e., C@Ni-F. The as-prepared C@Ni-F electrode has been used for structural elucidation and morphology evolution studies. Field emission scanning electron microscopy analysis confirms the vertically grown nanosheets of the C@Ni-F electrode, which is further employed in the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), where excellent OER and HER performances with small overpotentials of 219 and 122 mV and with stumpy Tafel slopes, i.e., 27 and 53 mV dec–1, are respectively obtained, suggesting a bifunctional potential of the sprayed electrode material. Moreover, sustainable bifunctional performance of C@Ni-F proves considerable chemical stability and moderate mechanical robustness against long-term operation, suggesting that, in addition to being a healthy drink to mankind, coconut water can also be used for water splitting applications.

Abstract Mesoporous tungsten oxide nanobricks (WO3 NBs) are successfully prepared via a simple and cost-effective hydrothermal synthesis method. The as-synthesized WO3 NBs demonstrate a high sensitivity and selectivity when used for liquid ammonia and humidity sensor activities at room temperature (27 °C). The monoclinic crystal structure has beencorroborated from thex-ray diffraction studies and the specific surface area is estimated to be 38.74 m2g−1. A larger specific surface area has significantly facilitated a fast gas adsorption/desorption process. The WO3 NBs notably exhibite gas sensitivity and selectivity for volatile organic compounds (VOCs) such as ammonia; however, a moderate performance is displayed with different oxidizing and reducing agents at room-temperature, namely: toluene, methanol, ethanol, and acetone. The sensor has offered a commercial potential with an extremely high response (75%), a 15-day operational stability at 100 ppm concentration of ammonia, and a practically remarkable ultra-high 8/5 s response/recovery time. The WO3 NBs-based humidity sensor endows a 32% resistance response at 20% relative humidity, with a quick response/recovery time of 10/8 s; which is due to unique surface architecture of these NBs.

The cobalt ferrite (CoFe2O4) nanoparticle sensors, synthesized using cost-effective sol-gel auto-combustion method, are irradiated with 2 and 5 kGy γ-doses. Effect of γ-irradiation on the structure, morphology and porosity is studied initially and in the later stage, methanol, acetone, ammonia, ethanol and toluene volatile organic gases are exposed for monitoring their selectivity and sensitivity with pristine and γ-irradiated CoFe2O4 nanoparticle-pellet sensors. The 5 kGy γ-irradiated CoFe2O4 sensor reveals 70% response for ammonia (100 ppm) gas, with high selectivity and room-temperature chemical and environmental stabilities. For knowing the changes in the structure, morphology, porosity and gas sensing performance of CoFe2O4 sensors on γ-irradiation theoretical model has also been proposed and explored. Proposed γ-irradiation approach can be used for enhancing the sensitivity of other gas sensors at room-temperature.

Zinc ferrite ( ZnFe 2 O 4 ) nanoparticles ( NPs ) , synthesized using a facile and cost-effective sol-gel auto-combustion method, were irradiated with 2 and 5 kGy γ -doses using 60 Co as a radioactive source. Effect of γ -irradiation on the structure, morphology, pore-size and pore-volume and room-temperature ( 300 K ) gas sensor performance has been measured and reported. Both as-synthesized and γ -irradiated ZnFe 2 O 4 NPs reveal remarkable gas sensor activity to ammonia in contrast to methanol, ethanol, acetone and toluene volatile organic gases. The responses of pristine, 2 and 5 kGy γ -irradiated ZnFe 2 O 4 NPs are respectively 55%, 66% and 81% @100 ppm concentration of ammonia, signifying an importance of γ -irradiation

Thereby, due to increase in surface area and crystallinity on γ-doses, the γ-irradiation improves the room-temperature ammonia gas sensing performance of ZnFe2O4.
