ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2024; 31:43453-43475. [PMID: 38684612 DOI: 10.1007/s11356-024-33502-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 04/25/2024] [Indexed: 05/02/2024]
Abstract
Water contamination ranks highest among the challenges posed by the rapidly increasing environmental contamination, which is thought to be the most pressing issue globally. The development of innovative techniques for the successful removal of diverse types of undesirable pollutants from wastewater would therefore yield a huge return on investment. Nowadays, the removal of many organic and synthetic pollutants from the environmental matrix is anticipated to be possible by photocatalytic degradation, owing to its low energy consumption, high catalytic activity, and low overall cost. In this context, magnetic nanoparticles received greater attention as photocatalytic materials from the scientific community in wastewater treatment for the removal of different kinds of pollutants due to their specific properties. The present study provides an overview of the recent advances in water treatment using nickel ferrite nanoparticles and their nanocomposites as photocatalysts. Furthermore, a proposed mechanism for these photocatalysts to generate active free radicals under visible and ultraviolet light has been described. The review concludes that photocatalysts based on NiFe2O4 have potential applications in water purification technologies. However, more research is still needed to determine their practical application in water treatment facilities.

Abstract
Since ancient times, medicinal plants have been used as traditional medicine to treat a variety of ailments. Aloe vera (AV) gel's therapeutic potential is one of the most effective approach in the fabrication of functional materials. The current study aimed to prepare the AV and chitosan (CS) membranes using various cross-linkers that were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform-infrared (FT-IR) spectroscopy, thermal gravimetric analysis (TGA), and ultraviolet-visible (UV-Visible) techniques, as well as swelling ratio and antimicrobial studies. SEM analysis revealed that the membrane is porous, with interconnected pores. The inclusion of AV contents in the membrane improved thermal stability and crystallinity. The swelling ratio of the ACPG-3 membrane with a 2:1 CS to AV ratio was 366%. The membranes showed promising antimicrobial activity against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Pasteurella multocida strains. The findings revealed that polymeric CS/AV membranes have effective potential for use in the biomedical field.

Abstract
This study focusses on the fabrication of nano-carriers for delivery of ciprofloxacin through the nanoprecipitation process. This was done to examine the release of drug at the pH of stomach to find out the antibacterial action of ciprofloxacin loaded nanoparticles (NPs). Prepared NPs were characterized by Fourier Transform Infra-Red (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), and particle size analyzer (PSA) techniques. Drug yield, loading, and sustained release was studied as function of time (up to 8 h). Antibacterial activity of ciprofloxacin loaded NPs were also determined against different gram-positive and gram-negative bacteria. Results revealed that nanoprecipitation is a suitable method for encapsulation of ciprofloxacin in poly(lactic-co-glycolic acid) PLGA NPs. The drug yield and drug loading were found to be 60%. The size range of NPs observed by PSA was in the range of 5.03-6.60 nm. It can be concluded that nanoformulation of ciprofloxacin loaded PLGA NPs can be used in stomach for longer period of time to enhance the bioavailability of the drug.

Abstract
Abstract
Sol-gel auto combustion method was adopted to fabricate magnesium ferrite (MgFe2O4) nanoparticles. The structural and morphological properties was studied by XRD, FTIR, and SEM analysis. The average particle sizes of MgFe2O4 was in the range of 35–55 nm. The octahedral & Tetrahedral bond lengths, R
AE (tetrahedral edge length), R
BE (shared octahedral edge length) and R
BEU (individual octahedral edge length), cationic radii (tetra and octa-sites) were also determined. The magnetic strength also showed direct reliance on bond angle and indirect to bond length. Hoping length L
a and L
b and bond angles are also measured. The frequency dependent conductivity and dielectric properties of MgFe2O4 were investigated by Impedance analyzer. The photocatalytic activity (PCA) is appraised against MB (methylene blue) dye and MgFe2O4 calcined at 800 °C showed promising degradation (78%) under visible light irradiation. The findings revealed that MgFe2O4 is can harvest the solar light, which could be employed for the remediation of wastewater contains textile dyes.

Abstract
The science of nanotechnology is expanding daily and has the potential to benefit people. Moringa oleifera is an abundant source of phenolic compounds, which are bioactive substances. It is recognised as a necessary plant because of its medicinal potential and a wide variety of health benefits. The aim of the current study is to examine the antioxidant, antibacterial, and cytotoxicity effects of five nanoparticles (La2O3, CuO, Fe2O3, Ag, and ZnO) made using bioactive chemicals in the aqueous extract of Moringa oleifera leaves on four human cell lines (T47D, HepG2, A549, and Wi38). The UV-visible spectroscopy analysis with a surface plasmon peak in the 300-490 nm range and the value of the zeta potential of the various biosynthesized nanoparticles ranged from + 31 to + 37 mV, indicated the repulsion between the particles and the stability of the formulation nanoparticles confirmed the formation of all nanoparticles. Additionally, the DPPH method was used to assess the antioxidant activity of five distinct metal nanoparticles. The results show that this method works in parallel and is dependent on both the concentration of NPs and the incubation time. The anticancer effect of synthesized nanoparticles against four different cell lines has been tested. The cytotoxicity assay showed a dose-dependent and time-dependent effect of nanoparticles. The obtained results conclude that acceptable potency against T47D and A549 cell lines with IC50 ranged from 38 to 210 μg/mL and 26 to 115 μg/mL, respectively. However, HepG2 and Wi38 cell lines showed relatively higher resistance against all tested nanoparticles when compared with Doxorubicin. Moreover, the antibacterial results revealed that silver nanoparticles exhibited the highest antibacterial activity against both Enterococcus faecalis and Staphylococcus aureus. Nanoparticles' high therapeutic activity at low concentrations opens up new avenues for the development of novel therapeutic approaches against human pathogens.

Abstract
The volatiles chemical composition and biological attributes of coriander
(Coriandrum sativum L.) leaves essential oil obtained by
two extraction techniques namely supercritical fluid extraction and
hydro-distillation is appraised. The coriander essential oil yield (.12%) by
hydro-distillation was slightly higher than that of supercritical fluid
extraction (.09%). The physico-chemical variables of the essential oil obtained
from both the techniques varied in significantly (P < .05). GC-MS analysis
identified 23 different components in supercritical fluid extracted oil and 18
components in hydro-distilled essential oil having linalool as major component
(51.32% and 61.78%, respectively) followed by phytol (12.71%). The oil recovered
by supercritical fluid extraction exhibited greater DPPH radical scavenging
activity as well as reducing power as compared to the essential oil obtained by
hydro-distillation technique along with a stronger biofilm inhibition and least
hemolysis. The results of antimicrobial activity revealed that super critical
fluid extracted essential oil has potent antifungal and antibacterial activity
against P. multocida and A alternata, whereas
hydro-distilled essential oil displayed better antimicrobial potential against
E coli and A niger. Overall, these results
depict that supercritical fluid extraction is superior than hydro-distillation
with regard to isolation of better-quality coriander essential oil for
nutra-pharmaceutical developments.

Abstract
Co-Ni ferrite is one of the crucial materials for the electronic industry. A partial substitution with a rare-earth metal brings about modification in crystal lattice and broadens knowledge in the discovery of new magnetic material. Current work reports a Ga3+ substitution in the Co-Ni ferrite with composition Co0.5Ni0.5Fe2-xGaxO4 (where x = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0), herein referred to as spinel ferrite microspheres (CoNiGa-SFMCs). The samples were crystallized hydrothermally showing a hollow sphere morphology. The crystal phase, magnetic, morphology, and optical behaviour were examined using various microscopy and spectroscopic tools. While the XRD confirmed the phase of SFMCs, the crystallite size varied between 9 and 12 nm. The Tauc plot obtained from DRS (diffuse reflectance spectroscopy) shows the direct optical energy bandgap (Eg) of the products, with the pristine reading having the value of 1.41 eV Eg; the band gap increased almost linearly up to 1.62 eV along with rising the Ga3+ amount. The magnetic features, on the other hand, indicated the decrease in coercivity (Hc) as more Ga3+ is introduced. Moreover, there was a gradual increase in both saturation magnetization (Ms) and magnetic moment (nB) with increasing amount of Ga3+ till x = 0.6 and then a progressive decline with increases in the x content; this was ascribed to the spin-glass-like behavior at low temperatures. It was detected that magnetic properties correlate well with crystallite/particle size, cation distribution, and anisotropy.

Abstract
Abstract
The present study focuses on iron nanoparticles (Fe NPs) biosynthesis, characterization and photocatalytic activity (PCA) appraisal for methylene blue dye degradation. A green rapid biogenic synthesis route was employed for synthesis of Fe NPs using banana peel extract. The synthesized Fe NPs was characterized by XRD (X-ray diffraction), SEM (scanning electron microscopy) and EDX (energy dispersive X-ray) techniques. These analysis confirmed the synthesis of zero valent Fe NPs with high crystallinity, purity and semi spherical in shape. The photocatalytic activity was assessed under ultra violet irradiation and under optimum conditions, 87% degradation of MB dye was obtained for 72 min of irradiation, which revealed promising catalytic efficiency of the Fe NPs. The result shows that photocatalytic activity of Fe NPs is promising and could possibly be used to treat dyes in industrial effluents and the use of green synthetic protocol is suggested due to its ecofriendly nature.

Abstract
In this study, the samples of the ZnFe2O4 (ZFO) spinel ferrites nanoparticles (SFNPs), Co0.5Ni0.5Ga0.01Gd0.01Fe1.98O4 (CNGaGdFO) SFNPs and (Co0.5Ni0.5Ga0.01Gd0.01Fe1.98O4)x/(ZnFe2O4)y (x:y = 1:1, 1:2, 1:3, 2:1, 3:1 and 4:1) (CNGaGdFO)x/(ZFO)y spinel ferrite nanocomposites (NC) have been synthesized by both sol-gel and Green pulsed laser ablation in liquid (PLAL) approaches. All products were characterized by X-ray powder diffraction (XRD), scanning and transmission electron microscopies (SEM and TEM), elemental mappings and energy dispersive X-ray spectroscopy (EDX). It was objected to tune the magnetic properties of a soft spinel ferrite material with a softer one by mixing them with different fractions. Some key findings are as follows. M-H investigations revealed the exhibition of ferrimagnetic phases for all synthesized samples (except ZnFe2O4) that were synthesized by sol-gel or PLAL methods at both 300 K and 10 K. ZnFe2O4 ferrite NPs exhibits almost paramagnetic feature at 300 K and glass-like phase at very low temperatures below 19.23 K. At RT analyses, maximum saturation magnetization (MS) of 66.53 emu/g belongs to nanocomposite samples that was synthesized by sol-gel method and x:y ratio of 1:3. At 10 K analyses, MS,max = 118.71 emu/g belongs to same nanocomposite samples with ratio of 1:3. Maximum coercivities are 625 Oe belonging to CNGaGdFO and 3564 Oe belonging to NC sample that was obtained by sol-gel route having the 3:1 ratio. Squareness ratio (SQRs = Mr/MS) of NC sample (sol-gel, 4:1 ratio) is 0.371 as maximum and other samples have much lower values until a minimum of 0.121 (laser, 3:1) assign the multi-domain wall structure for all samples at 300 K. At 10 K data, just CNGaGdFO has 0.495 SQR value assigning single domain nature. The maximum values of effective crystal anisotropy constant (Keff) are 5.92 × 104 Erg/g and 2.4 × 105 Erg/g belonging to CNGaGdFO at 300 K and 10 K, respectively. Further, this sample has an internal anisotropy field Ha of 1953 Oe as largest at 300 K. At 10 K another sample (sol-gel, 3:1 ratio) has Ha,max of 11138 Oe which can also be classified as a soft magnetic material similar to other samples. Briefly, most magnetic parameters of NCs that were synthesized by sol-gel route are stronger than magnetic parameters of the NCs that were synthesized by PLAL at both temperatures. Some NC samples were observed to have stronger magnetic data as compared to magnetic parameters of Co0.5Ni0.5Ga0.01Gd0.01Fe1.98O4 NPs at 10 K.
