The inverse spinel nanocrystalline pure and doped nickel ferrite particles were synthesized by co-precipitation method. The thick films of both pure and doped nickel ferrite nanoparticles were prepared by coating the material on glass substrate via screen printing method. The XRD was used to confirm cubic, crystalline nickel ferrites. The scanning electron microscopy confirms nanosized, cubic nanoparticles of nickel ferrite, and their morphology was investigated. The energy-dispersive spectroscopy was used to comprise elemental composition for pure and doped ferrites. Transmission electron microscopy was attributed for investigation of surface morphology, crystal structure identification of nickel ferrites. The FT-IR was used to find the vibrational frequencies, symmetric, asymmetric stretching and bending modes of metal oxide linkage. The thick films of nickel ferrite were employed for sensing phenomenon of gases such as LPG, NO 2 , CH 3-OH, C 2 H 5-OH, NH 3 and petrol vapours. The pure nickel ferrite showed excellent results for ammonia and nitrogen dioxide gases up to 90.42 and 86.42, respectively. Manganese-and cobalt-doped ferrites were excellent for ammonia and petrol vapours. Modified nickel ferrite effect of dopants cobalt and manganese was investigated. Pure and doped ferrites showed excellent response and recovery for ammonia, NO 2 , petrol vapours and LPG gases.

“…It was found in our study that, as the dopant content, i.e., when Nd increases from 0.0 to 0.2, the anti-gram-positive bacterium activity of NPs was also increased, although anti-gram-negative bacterium activity was found negligible which is in agreement with the studies conducted by Ashour et al, 2018. It is of paramount importance to mention that antibacterial studies conducted by Ishaq et al [32] using nickel ferrite NPs also found no activity against E. coli and showed activity only against S. aureus. This specificity of action could be attributed to the difference in the cell wall thickness and the amount of lipopolysaccharide content among gram-positive and gram-negative bacteria [33].…”

Neodymium (Nd)-substituted cobalt ferrite nanoparticles (NPs), i.e., CoNdxFe2−xO4 (0.0 ≤ x ≤ 0.2) NPs, were synthesized by the sonochemical method. The compositional characterization was done by scanning electron microscopy (SEM) equipped with energy-dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM). Antistaphylococcal activity was found to be enhanced, i.e., survival rate was 50%, 45%, 40%, and 30% with the increase in the ratio of Nd (0.0 ≤ x ≤ 0.2), whereas anticandidal activity was found efficient, i.e., 9%, 20%, 22%, and 40% survival rate at all the four ratios. The morphogenesis studies indicated that the synthesized metal–ligand, improves the antimicrobial capacity by binding them strongly to the microbial walls. To the best of our knowledge, this is the first report which demonstrates the series of CoNdxFe2−xO4 (0.0 ≤ x ≤ 0.2) NPs being active towards Staphylococcus aureus and Candida albicans and encourages its potential candidature for pharmaceutical and biomedical purposes.

“…In the case of undoped LaCrO 3 , the sharp peak was found to be at 4.8 keV for lanthanum and at 5.4 keV for chromium in the EDS spectrum which we have presented previously. Figure 3a-d demonstrates the case of Sn-doped EDS spectrum, in which sharp peak was found to be at 4.8 keV for lanthanum, 5.4 keV for chromium and at 0.6, 3.4 keV for tin, all this information was obtained from EDS and for all concentration of Sn which is found to be near about same [20,27,28]. Also, Table 2 shows the elemental composition of doped and undoped nanostructures with respect to elemental weight percent.…”

The present work emphasizes the effect of the use of Sn, with different concentrations, over the structural properties and sensing applications of LaCrO 3 . In this work, LaCrO 3 nanostructures were modified with different concentration of Sn (0.2 M %, 0.4 M %, 0.6 M % and 0.8 M %).Different modified Sn-doped LaCrO 3 was synthesized by sol-gel method and followed by preparation of thick films via a conventional screen printing approach. The characterizations done by means of X-ray diffraction (XRD), energy-dispersive X-ray (EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the confirmation of a Sn-doped LaCrO 3 crystal structure and its morphology, respectively. These oxides were formulated to identify various air pollutants such as CO 2 , ethanol, H 2 S, NH 3 , NO 2, and acetone. The Sn-doped LaCrO3 with 0.4 M % Sn displayed higher gas response to ethanol vapor at the range of 150-250 °C. The sensors additionally demonstrated proper recovery and acceptable stability. Graphic abstractThe graphical abstract demonstrates the in situ synthesis of Sn-doped LaCrO 3 by sol-gel method. Similarly, it shows its characterization and finally, the thick films of doped Sn demonstrate best selectivity for ethanol.Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creat iveco mmons .org/licen ses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
