This study was planned to explore the in-vitro and in-vivo therapeutic significance of Paeonia emodi-mediated zinc oxide nanoparticles (ZnO NPs) against the Staphylococcus aureus and Escherichia coli. The texture parameters were derived from nitrogen adsorption–desorption data using Brunauer–Emmett–Teller (BET) and Barrett–Joyner–Halenda (BJH) methods, and the surface area (SBET) was found to be 214 m2/g with a pore size of 2.3 nm. The crystallographic parameters were investigated through X-ray diffraction analysis, and the calculated crystallite size is 29.13 nm. The microstructure was examined through transmission and scanning electron microscopies (TEM and SEM, respectively), and the average particle size estimated from a TEM image is 44.40 nm. The chemical composition and attached function groups were identified through energy-dispersive X-ray and Fourier transform infrared spectroscopies. The in-vitro minimum inhibitory concentration (MIC) for both bacterial species results was found less than 2 μg/ml. The tolerance limit of mouse models was evaluated by the inoculation of different concentrations of ZnO suspension where the concentration above 23 ppm was proved lethal. The maximum infection was caused in mouse models by inoculation of 3 × 107 CFUs (Colony forming unit) of the both bacterial species. The concentration higher than 3 × 107 CFUs led to the ultimate death of the mice. The histopathological and hematological studies reveal that the after simultaneous inoculation of both ZnO NPs and bacterial suspensions (tolerated amount), no/negligible infection was found in the mice model.

In this study, a composite of zerovalent copper-biochar was investigated for its ability to remove lead from water. The prepared material was characterized by using scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR), X-ray diffractomter (XRD), and X-ray photoelectron spectroscopy (XPS). The pH effect on adsorption of lead was investigated within the range of 2–8 and the effect of temperature was studied at 303, 308, 313, and 318 K. The kinetics of lead adsorption on biochar composite was evaluated and the equilibrium time of 12 hr was established. To further evaluate the nature of adsorption, Langmuir model was tested and the adsorption capacities were evaluated for lead adsorption on the surface of copper biochar composite. The activation energy, entropy, and enthalpy values indicated the adsorption phenomenon to be chemisorptive and spontaneous in nature. Comparison of adsorption capacities with the reported adsorbents in the literature concluded zerovalent copper-biochar composite to be an efficient adsorbent for the removal of lead in the experimental conditions under study. Research Highlights Highly efficient composite of zerovalent copper with biochar was synthesized for lead adsorption. XPS and XRD shows the presence of zerovalent copper in the biochar composite. pH and temperature were the main governing factors in the adsorption process. Adsorption capacity for lead is higher than many of the reported adsorbents.

The Paeonia emodi (P. emodi)-mediated iron oxide nanoparticles (Fe2O3 NPs) were screened for in-vitro and in-vivo antibacterial activity against the Staphylococcus aureus (S. aureus) (ATCC #: 6538) and Escherichia coli (E. coli) (ATCC #:15224). The synthesized Fe2O3 NPs were characterized via nitrogen adsorption-desorption process, X-ray diffractometer (XRD), transmission and scanning electron microscopies (TEM and SEM), energy dispersive X-ray (EDX) and Fourier transform infrared (FTIR) spectroscopies. The SBET was found to be 94.65 m2/g with pore size of 2.99 nm, whereas the average crystallite and particles size are 23 and 27.64 nm, respectively. The 4 μg/mL is the MIC that inhibits the growth of E. coli, whereas those for S. aureus are below the detection limit (<1.76 μg/mL). The tolerance limit of the mice model was inspected by injecting different concentration of Fe2O3 NPs and bacteria suspensions. The 14 ppm suspension was the tolerated dose and the concentration above were proved lethal. The most severe infection was induced in mice with injection of 3 × 107 CFUs of both bacteria, while the inoculation of higher concentrations of bacterial suspensions resulted in the mice’s death. The histopathological and hematological studies reveals that the no/negligible infection was found in the mice exposed to the simultaneous inoculation of Fe2O3 NPs (14 ppm) and bacterial suspensions (3 × 107 CFUs).

The antimicrobial drug resistance is increasing with the passage of time due to wide and improper use of broad spectrum drugs and the demand of the new drug increases day by day. The present study was planned to encounter this problem by synthesizing titanium dioxide nanoparticles (TiO2 NPs) by an eco‐friendly route using Cannabis sativa leaves extract. The synthesized TiO2 NPs were calcined at 100, 300, 600, and 900°C in a muffle furnace. The crystallographic parameters were studied by X‐ray diffraction and the phase transition occurred above 600°C. The surface morphology of the synthesized samples was studied by transmission electron microscopy (TEM), and scanning electron microscopy (SEM) and the particle size was measured through the ImageJ software. The elemental composition and purity of all the samples were studied by performing energy dispersive X‐ray (EDX). All the synthesized TiO2 NPs were tested for their antimicrobial effect against Gram‐positive and Gram‐negative bacteria using the agar well diffusion method. The activity was found higher against Gram‐negative bacteria and compared to Gram‐positive bacteria.

The synthesis of zinc stannate nanocomposite (Zn2SnO4 NC) was carried out using an environment friendly process that included the use of Ficus carica (F. carica) leaves extract as a capping and reducing agent. X-ray diffraction (XRD) analysis was used to analyze the structural and crystallographic parameters, and the crystallite was discovered to have cubic geometry. The elemental composition of the studied Zn2SnO4 NC was investigated using energy dispersive X-ray (EDX), which revealed that it was extremely pure. The band gap (3.12 eV) was calculated through Tauc plot using diffuse reflectance (DRS) data where the functional groups were explored through Fourier transform infrared (FTIR) spectroscopy. Prior to the photocatalytic reaction, some preliminary experiments were performed, which proposed that pH 9 is suitable for the mineralization of methylene blue (MB) (10 ppm) in the presence of 20 mg of Zn2SnO4 NC and simulated solar light. The 96 % of MB was degraded in 80 min with the degradation rate of 0.038 min-1.

The current study was planned to synthesize copper oxide nanoparticles (CuO NPs) using aqueous Fumaria indica (F. indica) plant extract and was calcined at 100, 300, 600 and 900 °C using Muffle furnace. The X-ray diffraction analysis reveals that crystallinity and crystallite size increase (from 14.9 to 79.29 nm) with increasing calcination temperature. The microstructure was analyzed through scanning electron microscopy, while the constituent elements were identified through energy-dispersive X-ray. The diffuse reflectance spectroscopy analysis was carried out and the optical band gap was determined through Tauc plot, which was found to decrease (from 1.82 to 1.46 eV) with increasing calcination temperature. The surface functional moieties were identified by performing Fourier transform infrared spectroscopy. Agar well diffusion process was followed to screen CuO NPs against Gram-positive bacteria and Gram-negative bacteria, where higher activity was found against Gram-negative bacteria. The antioxidant activity of CuO NPs was evaluated during the neutralization ABTs free radical, thus it can be used to reduce the damaging effects of antioxidants.

The interesting properties of hexagonal boron nitride (h-BN) and its potential uses in thermo-structural advanced applications have been limited or restricted by its inherent brittleness, which can easily be eliminated by its fibers (h-BN) in nanoscale dimensions. The current study is based on the synthesis of nanoscale 10B-enriched fibers of h-BN (10BNNFs) from 10B in the precursors instead of B in two-hour annealing at 900 °C and one-hour growth at 1000 °C. All of the 10BNNFs are randomly curved and highly condensed or filled from 10h-BN species with no internal space or crack. XRD peaks reported the 10h-BN phase and highly crystalline nature of the synthesized 10BNNFs. 10h-BN phase and crystalline nature of 10BNNFs are confirmed from high-intensity peaks at 1392 (cm−1) in Raman and FTIR spectroscopes.

The titanium dioxide nanocatalyst (TiO2:NC) was fabricated by chemical precipitation method and annealed at different temperatures. The texture parameters was estimated by Barrett–Joyner–Halenda (BJH) and Brunauer–Emmett–Teller (BET) utilizing nitrogen adsorption–desorption data. The crystal phase transition, enhanced crystallinity and increase in crystallite sizes with temperature were studied by using X-ray diffractograms (XRD). Coinciding with an increase in crystallite size supervising annealing temperatures, the surface area of the TiO2:NC decreases. The average grain size as calculated from scanning electron microscopy (SEM) initially decreases with increasing annealing temperature (300 °C), whereas further increase in annealing temperature (600 °C), is accompanied by the increase in grain size. A red shift was observed in the diffuse reflectance spectra (DRS) caused by a decrease in band gap energy with rising annealing temperatures. The chemical composition was examined by using Fourier transform infrared (FTIR) and energy dispersive X-ray (EDX) spectroscopies. All the annealed TiO2:NC samples were used as photocatalysts for the degradation of rhodamine 6G (R6G) under simulated solar light source. The TiO2:NC annealed at 600 °C have a higher degradation rate constant than the other samples.

Astract Cobalt oxide nanoparticles (Co3O4-Nps) have many applications and now days the biological methods of synthesis of these nano particles are preferred over other methods because of associated benefits. In this study, Co3O4-Nps nanoparticles were synthesized by green method by using leaves extract of Populus ciliata (safaida) and cobalt nitrate hexahydrate as a source of cobalt. The synthesized nanoparticles were analyzed by using techniques such as fourier transform spectroscopy (FTIR), ultra violet-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Antibacterial activities of the synthesized cobalt oxide nanoparticles were evaluated against gram negative and gram positive bacteria and found active against Escherichia coli (E.coli), Klebseilla pneumonia (Pneumonia), Bacillus subtillus (B.subtillus) and Bacillus Lichenifermia (B. lichenifermia). The activity results were analyzed statistically by one-way ANOVA, with "Dunnett's Multiple Comparison Test". The maximum mean activity (21.8±0.7) was found for Bacillus subtilis and minimum mean activity (14.0±0.6) was observed for Escherichia coli. Key Words: Populus ciliata, cobalt oxide, NPs, bacteria, activity.

The tin dioxide nanoparticles (SnO2 NPs) were fabricated via eco-friendly process using Daphne mucronata (D. mucronata) leaves extract as capping and reducing agent. The N2 adsorption/desorption experiment was performed to determine the surface area by Brunauer-Emmett-Teller (BET) method and SBET was found to be 147 m2/g. The crystalline nature and lattice parameter was studied by X-ray diffraction (XRD) and calculated crystallite size is 15.63 nm. The surface morphology was examined by scanning electron microscopy (SEM) and the estimated average particle size is 64 nm. The percentage composition and purity of the SnO2 NPs was determined by energy dispersive X-ray (EDX). The raman active modes were identified by using raman spectroscopy while functional groups upon the surface were studied by using fourier transform infrared (FTIR) spectroscopy. The photocatalytic performance of SnO2 NPs was examined against Rhodamine 6G (R6G) and 99.70 % rhodamine 6G (R6G) were degraded in 390 min with the degradation rate of 0.0148 per min. The SnO2 NPs were screened against the selected microorganisms and the order of antimicrobial activity is given as; Gram negative bacteria (GNB) > Gram positive bacteria (GPB) > fungi.

The zinc stannate nanostructure was synthesized via sol-gel route and its physicochemical, adsorption and photocatalytic properties were studied. The specific surface area (S) was calculated by Brunauer–Emmett–Teller (BET) and Barrett, Joyner and Halenda (BJH) methods using N2 adsorption-desorption. The SBET and SBJH were found to be 105 and 138 m2/g respectively with the average pore size of 2.5 nm. Based on diffraction data, cubic geometry was assigned to the crystallites with average size of 31.74 nm. The morphology of the particles was studied though transmission electron microscopy (TEM) and scanning electron microscopy (SEM) and the average particles size as calculated from TEM was 21.6 nm. The band gap calculated from the diffuse reflectance spectrum was 3.36 eV. The percentage composition and purity were determined by energy dispersive X-ray (EDX), whereas surface functional moieties were detected by Fourier transform infrared (FTIR) spectroscopy. The batch method was used to study the adsorption of Cr(VI) ions by varying, initial electrolyte concentration, pH, and temperature of solution. The parameters extracted from Langmuir and Freundlich models shows that the adsorption process was more feasible at higher temperature and lower pH. The maximum sorption capacity of the adsorbent was found to be 32.81 mg/g. The 1:1 exchange mechanism was proposed between Cr(VI) and surface protons while the thermodynamic study reveals the endodermic nature of the adsorption process. The photocatalytic performance of the zinc stannate was examined against Rhodamine 6G where 98.17 % degradation was achieved in 390 min.
