The innovation and development of water purification methods have been at the center of extensive research for several decades. Many nanoparticles are frequently seen in industrial waste water. In this research, zinc oxide nanoparticles (ZnO) were synthesized following an autocombustion method with and without honey capping. Structural crystallinity and bonding structure were examined via X-ray diffraction (XRD) analysis and Fourier transform infrared (FTIR) spectroscopy. Optical behavior was analyzed using ultraviolet–visible (UV–Vis) spectroscopy and photoluminescence (PL). Size estimation and surface morphology were studied using scanning electron microscopy (SEM), while energy-dispersive spectroscopy (EDS) was performed to analyze the sample purity and elemental composition. The photocatalytic degradation of methylene blue (MB) by ZnO was assessed as it is an efficient water treatment process with high potential. The biological activity of ZnO nanoparticles was also investigated in terms of antibacterial and antifungal activities against different bacterial and fungal species. Surprisingly, the as-synthesized ZnO nanoparticles were found to be substantially bioactive compared to conventional drugs. Honey-mediated nanoparticles displayed 86% dye degradation efficiency, and that of bare ZnO was 60%. Therefore, the involvement of honey in the synthesis of ZnO nanoparticles has great potential due to its dual applicability in both biological and environmental remediation processes.

Lithium manganese phosphate (LiMnPO4) and a series of chromium-doped lithium manganese phosphate with variation in Cr content LiCrxMn1−xPO4 (x = 0.03, 0.06, 0.1) were prepared via conventional sol-gel method and their dielectric properties have been explored as a function of frequency. The structure and morphology were investigated by X-ray diffraction technique (XRD), Fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The influence of frequency upon electrical conductivity as well as di-electric properties of the as-synthesized LiCrxMn1−xPO4 materials have been analyzed by dielectric parameters and AC conductivity using impedance analyzer. It was observed that dielectric constant increased with frequency at lower chromium concentration while at higher chromium contents, the dielectric constant was decreased with increasing frequency. Hence, the composition with highest Cr content (ie, x = 0.1) is proved as best material for various applications owing to its lowest AC-conductivity and lowest dielectric loss. Therefore, it is revealed that chromium doping is quite advantageous for performance of LiMnPO4 in device applications as Cr doped LiMnPO4 unveiled improved dielectric loss.

AMR (Antimicrobial-resistant) pathogens like MRSA (Methicillin-Resistant Staphylococcus aureus) have become prodigious peril to human health in the past couple of years with the failure of various antifungals and antibiotics in treating mild to chronic mycoses and septicemia. In the grave concern for the rising contagions, Azo-Schiff Bases with dual functionality and far-ranging pharmacological potential has been considered an excellent target for antimicrobial investigations. A diversity of homocyclic and heterocyclic organic precursors has been utilized for submitting novelty in the Azo-Schiff Base Ligands (ASBLs). In addition, the d-block transition metal chelates of ASBLs with infinitely diverse features have also been synthesized and characterized exploiting the classical and advanced analytical techniques. These resourceful coordination compounds owing to their characteristic polydentate ligands with multiple coordination sites, the geometry of complexes, and redox nature of metal centres are bestowed with the structural tunability to reinvigorate their potential applications. A detailed literature survey divulged that no compendious review has yet been published on ASBL-metal derivatives. Therefore, the present study encompasses the research undertaken during the last two decennia for the development and in vitro antimicrobial screening of these prospective drug agents.

The development of cost-effective and ecofriendly approaches toward water purification and antibacterial activity is a hot research topic in this era. Purposely, strontium-doped zinc selenide (Sr-doped ZnSe) nanoparticles, with different molar ratios of Sr2+ cations (0.01, 0.05, and 0.1), were prepared via the co-precipitation method, in which sodium borohydride (NaBH4) and 2-mercaptoethanol were employed as reducing and stabilizing agents, respectively. The ZnSe cubic structure expanded by Sr2+ cations was indicated by X-ray diffraction (XRD) analysis. The absorption of the chemical compounds on the surface was observed via Fourier transform infrared (FT-IR) spectroscopy. The optical orientation was measured by ultraviolet–visible diffused reflectance spectroscopy (UV-DRS) analysis. The surface area, morphology, and elemental purity were analyzed using field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), and energy-dispersive spectroscopy (EDS) analyses. The oxidation state and valency of the synthesized nanoparticles were analyzed using X-ray photoelectron spectroscopy (XPS). Sr-doped ZnSe nanoparticles were investigated for photocatalytic degradation of methyl orange (MO), and their antibacterial potential was investigated against different bacterial strains. The antibacterial activity examined against Staphylococcus aureus and Escherichia coli implied the excellent biological activity of the nanoparticles. Moreover, the Sr-doped ZnSe nanoparticles were evaluated by the successful degradation of methyl orange under visible light irradiation. Therefore, Sr-doped ZnSe nanoparticles have tremendous potential in biological and water remediation fields.

Iron–copper bimetallic nanoparticles (Fe-Cu BNPs) were prepared via a green synthesis route. Ixora finlaysoniana has been used in this study as a capping and stabilizing agent in the modification of Fe-Cu BNPs. As-synthesized BNPs were characterized using different techniques including UV/Vis spectrophotometry, FTIR, XRD and SEM. A particle size analyzer and SEM studies indicated the particle size to be in the range of 50–200 nm. In addition, degradation of MB dye in an aqueous system and radical-scavenging potential in a DPPH assay were also examined using BNPs. Methylene blue dye degradation in 17 min was monitored with UV/Vis spectrophotometry, which exhibited the efficiency of Fe-Cu BNPs. Bimetallic nanoparticles were also found to be efficient in neutralizing DPPH free radicals. Furthermore, kinetic studies of both dye degradation and radical scavenging potential are reported in this article. Subsequently, Fe-Cu BNPs synthesized via a green and sustainable method can be employed for dye degradation and free radical-scavenging activities.

Reduced graphene oxide based iron oxide modified titania (rGO-Fe3O4/TiO2) was developed as a low-cost, stable, and reproducible photocatalyst, synthesized by conventional hydrothermal route. Structural and morphological features were investigated by X-Ray diffraction (XRD), Thermogravimetric analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS). The incorporation of rGO-Fe3O4 to TiO2 shifted the light absorption of TiO2 from ultraviolet (UV) to visible region. The band gap energy of the synthesized photocatalyst rGO-Fe3O4/TiO2 reduced to 2.6 eV as compared to TiO2 (3.2 eV) which shifted the light absorption into visible region in order to utilize the solar energy effectually. The as-proposed rGO-Fe3O4/TiO2 and TiO2 photocatalysts were used for the photo-degradation of malachite green (MG) and methylene blue (MB) degradation. The as-prepared photocatalyst rGO-Fe3O4/TiO2 exhibited commendable photocatalytic efficiency (99%) comparative to pure TiO2 (67%) under visible light in 55 min for MG degradation. The active species were also identified using various scavengers by trapping holes and radicals generated during the photocatalytic degradation process. Subsequently, such photo-degradation output inferred that this ternary nanocomposite partakes a great potential for visible light driven MG and MB photocatalytic degradation.

This work intended to enhance the unique and outstanding properties of lanthanum by synthesizing its nanocomposite. A lanthanum-based nanocomposite was prepared by a simple and cost-effective “co-precipitation” method. Lanthanum nitrate (La (NO3)3) and zinc nitrate (Zn (NO3)2) were used as precursors. The lanthanum/zinc oxide nano composite formed was then calcined at 450 °C for 4 h in order to obtain a fine powder with size in the nano range of 1–100 nm. Characterization of the prepared catalyst was done by ultraviolet/visible spectroscopy, Fourier transform infrared spectroscopy, and photoluminescence. Crystallinity and morphology were found by X-ray diffraction and scanning electron microscopy. The synthesized nanocomposite material was also tested for heterogeneous catalytic applications of 4-nitrophenol (4-NP) reduction into 4-aminophenol (4-AP). It was found to be successful in complete reduction of 4-NP with enhanced catalytic performance.

Lead (Pb) is one of the most toxic elements on earth. The main origins of Pb pollution are automobiles, paint and electroplating industries. Pb-induced stress has very toxic effects on plant growth and biomass. The concentration of reactive oxygen species (ROS) in plant cells significantly increases under Pb stress, which interrupts the biochemical cycles in cells and leads to cell death. Therefore, it is essential to clean up the Pb-polluted soils. Among all techniques that are used to clean soil that is metal-contaminated, the best technique is phytoremediation. The present study intends to determine the role of citric acid (CA) and glutathione (GSH) in the phytoremediation of Pb by using castor bean plants. Plant biomass was significantly reduced due to Pb stress. Lead toxicity was also harmful to the photosynthetic pigments and antioxidant enzymes activities. In reverse, the content of malondialdehyde (MDA), H2O2 concentration and electrolyte leakage (EL) were increased under Pb stress. The combined application of GSH and CA enhanced photosynthetic pigments, antioxidant enzyme activities and plant biomass and minimized MDA, H2O2 and EL under Pb stress. The amount of Pb in roots and leaves remarkably increased by the joint application of CA and GSH. The combined application of CA and GSH (5 mM + 25 mM, respectively) was proven to be beneficial compared to the control. From the present results, we can conclude that the combined application of CA and GSH promoted the phytoremediation of Pb and helped the host plant to combat Pb toxicity.

Improvement in chitosan (CS) was achieved by solution casting using cellulose nanowhiskers (CNWs) and multiwall carbon nanotubes (MWCNTs) to synthesize CS/CNW functionalized/treated MWCNTs (CS/CNWs/f-MWCNTs) and CS/CNW untreated MWCNTs (CS/CNWs/Un-MWCNTs) nanocomposite films. A comparison between effects of f-MWCNTs and Un-MWCNTs on CS/CNWs matrix have been studied with respect to change in their physical and mechanical properties. The surface morphology, chemical composition, mechanical properties and temperature decomposition of CS/CNWs/f-MWCNTs and CS/CNW/Un-MWCNTs nanocomposite films were characterized by Energy Dispersion Spectroscopy (EDS), Field Emission Scanning Electron Microscope (FESEM), Fourier-Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA). FESEM has shown that f-MWCNTs and Un-MWCNTs were well dispersed in CS/CNWs structure. Decrease in film ductility was observed with addition of Un-MWCNTs or f-MWCNTs. Moreover, Tensile strength (TS) and Young’s modulus (YM) were increased with f-MWCNTs and seemed to be decreased in case of Un-MWCNTs. However, a decrease in elongation at break (EB) has experienced with addition of f-MWCNTs and Un-MWCNTs. Furthermore, thermal stability of chitosan composites presented a delay or prevention from degradation of CS/CNWs due to the strong interactions. Such modification in chitosan can improve its mechanical and surface properties. Hence, chitosan derived composites could achieve more applicability in packaging, medicinal and environmental applications.

Hybrid composites have great potential for specific strength and specific stiffness, effective in aerospace industries, submarines, and light-weight automotives. The mechanical strength and adhesiveness of hybrid laminates can be enhanced by effective use of matrix materials in different ratios of epoxy resin and epoxy hardener. Gentle use of resin and hardener in the fabrication of hybrid composites can alter tensile modulus, the bonding strength between matrix and fabric. Spectacular progress has been achieved by the selection of appropriate amounts of resin and hardener in the hybridization of composite laminate. Hybridization was made by Kevlar inorganic/organic fabrics and glass fabrics stacked with epoxy matrix material. To achieve the combination of mechanical properties and bonding strength, transparent epoxy resin and hardener of commercial grades mixed in various ratios are incorporated as matrix material to fabricate laminate. Three different sheets, named A (3:2), B (4:1), and C (2:3), were embedded by the hand layup method to prepare a hybrid composite. Experimental tests, according to ASTM 3039, were performed to determine the tensile mechanical properties. Peel tests, according to ASTM 6862-11, were performed to investigate the interlaminar strength between Kevlar and glass layers. Shore A and Shore C hardness durometers were used to find out the hardness of the specimens at different spots using the ASTM D-2240 standard. Finally, physical testing, such as density and then water absorption, was carried out using the ASTM D-570 standard to check the swelling ratio of the different specimens. The results obtained highlight that the specimen of the glass/Kevlar hybrid embedded in the ratio 3:2 in lamination has the best mechanical properties (tensile strength and hardness) and the lowest swelling ratio, while the material system in the ratio 4:1 shows the best interlaminar properties and adhesion capabilities.

Here, we have manufactured extremely porous photoelectrodes comprised of ZnO/TiO2 by adding lignocellulose (LC) fibers extracted from the self-growing plant (Lily) on fluorine-doped tin oxide (FTO) substrate using doctor blade technique for dye-sensitized solar cells (DSSCs) uses and first-principle calculations were performed for electronic band structures and density of state (DOS). Density functional theory (DFT) results revealed a high conductivity and narrow electronic bandgap after doping with LC. Experimental results showed the effect of the addition of LC in ZnO (ZnO + LC) and TiO2 (TiO2 + LC) on the structure, morphology, and power conversion efficiency (PCE) was studied in detail using powder X-ray diffraction, scanning electron microscope, UV–visible spectroscopy, and solar simulant. The addition of LC in ZnO/TiO2 increases the porosity and surface area for higher dye loading and light-harvesting while decreasing the backward scattering of electrons. These developments result in a 38% increase in PCE of (ZnO + LC) as related to the ZnO based DSSC and a 104% increase in the case of (TiO2 + LC) based DSSC. In this work, we express that the development of highly porous metal oxide nano-composites by mixing LC fibers which may solve the electrolyte leakage issue and enhance the porosity of the photoelectrodes and thus enhance the PCE of DSSCs.

This study focusses on the synthesis of silver nanoparticles (Ag-nPs) by citrus fruit (Citrus paradisi) peel extract as reductant while using AgNO3 salt as source of silver ions. Successful preparation of biogenic CAg-nPs catalyst was confirmed by turning the colorless reaction mixture to light brown. The appearance of surface Plasmon resonance (SPR) band in UV-Vis spectra further assured the successful fabrication of nPs. Different techniques such as FTIR, TGA and DLS were adopted to characterize the CAg-nPs. CAg-nPs particles were found to excellent catalysts for reduction of Congo red (CR), methylene blue (MB), malachite green (MG), Rhodamine B (RhB) and 4-nitrophenol (4-NP). Reduction of CR was also performed by varying the contents of NaBH4, CR and catalyst to optimize the catalyst activity. The pseudo first order kinetic model was used to explore the value of rate constants for reduction reactions. Results also interpret that the catalytic reduction of dyes followed the Langmuir–Hinshelwood (LH) mechanism. According to the LH mechanism, the CAg-nPs role in catalysis was explained by way of electrons transfer from donor (NaBH4) to acceptor (dyes). Due to reusability and green synthesis of the CAg-nPs catalyst, it can be a promising candidate for the treatment of water sources contaminated with toxic dyes.

Herin, we prepared silver NPs using jasmine flower extract. The green synthesis process reports a eco-friendly, nontoxic, cost-effective and simple approach to the synthesis of metal and metal oxide nanoparticles. Extract of jasmine flower acts as capping as well as stabilizing agent. The average crystalline size of the XRD pattern is estimated to be 40 nm. FT-IR (Fourier Transform Infrared) spectra confirm the existence of Ag NPs. The UV-Visible spectrum exhibits an absorption peak of between 380 and 440 nm. Structural analysis for silver nanofibers reveals with SEM and TEM technique. The antimicrobial activity of silver NPs was tested for both grams positive and negative bacteria by Agar well diffusion method. Methylene blue is used as a pollutant dye. Silver nanoparticles result in a maximum degradation efficiency of 78% at the end of 120 minutes.

In this article the NiO nanoparticles were synthesized by onion extract (green synthesis) as well as by quercetin (chemical method) which were synthesized successfully. Quercetin is one of the major phytochemical of red onion which was studied separately (as chemical) and in onion extract for the synthesis of NiO NPs. The comparative study shows that quercetin solution works as reducing and capping agent for the synthesis of NiO NPs meanwhile extraction of onion works in the same way. The characterization techniques as like XRD, UV/Vis spectroscopy, SEM and EDX were used, which shows that the synthesis results of chemical method was better than green synthesis. Antibacterial activity was done through disc diffusion method to observe the sensitivity of bacterial (Staph. Aureus, E.coli) strains.
