“…The average size estimated was 15 nm for AgNPs. It is reported earlier that proteins can bind to nanoparticles either through free amine groups and therefore, stabilization of the AgNPs by protein is a possibility ( Daniel and Astruc, 2004 ; Kawsar et al , 2009 ; Shahverdi et al , 2007 ; Chien et al , 2007 ; Ahmad and Sharma, 2012 ).…”

In the present study, rapid reduction and stabilization of Ag+ ions with different NaOH molar concentration (0.5 mM, 1.0 mM and 1.5 mM) has been carried out in the aqueous solution of silver nitrate by the bio waste peel extract of P.granatum. Generally, chemical methods used for the synthesis of AgNPs are quite toxic, flammable and have adverse effect in medical application but green synthesis is a better option due to eco-friendliness, non-toxicity and safe for human. Stable AgNPs were synthesized by treating 90 mL aqueous solution of 2 mM AgNO3 with the 5 mL plant peels extract (0.4% w/v) at different NaOH concentration (5 mL). The synthesized AgNPs were characterized by UV-Vis spectroscopy, TEM and SEM. Further, antimicrobial activities of AgNPs were performed on Gram positive i.e. Staphylococcus aureus, Bacillus subtilius and Gram negative i.e. E. coli, Pseudomonas aeruginosa bacteria. The AgNPs synthesized at 1.5 mM NaOH concentration had shown maximum zone of inhibition (ZOI) i.e. 49 ± 0.64 in E. coli, whereas Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilius had shown 40 ± 0.29 mm, 28 ± 0.13 and 42 ± 0.49 mm ZOI respectively. The MIC value of 30 μg/mL observed for E. coli Whereas, Staphylococcus aureus, Bacillus subtilius and Pseudomonas aeruginosa had shown 45 μg/mL, 38 μg/mL, 35 μg/mL respectively. The study revealed that AgNPs had shown significant antimicrobial activity as compared to Streptomycin.

“…The FTIR bands are indexed in the figure. The FTIR spectra of the extract showed strong bands at 3353, 1633, and 1225 cm −1 assigned to O-H stretching vibration of alcohols and phenols [27], C=O stretching vibration of tertiary amines [28], and C-O stretching of aromatic ethers [29]. The IR spectra of gold nanoparticles showed bands at 3270, 1651, and 1023 cm −1 corresponding to O-H stretching vibration of alcohols and phenols, C=O stretching vibration of tertiary amides, and C-OH stretching of primary alcohols, the silver showed bands at 3285, 1633, and 1025 cm −1 assigned to O-H stretching vibration of alcohols and phenols, C=O stretching vibration of Tertiary amides, and C-OH stretching of primary alcohols.…”

We report on rapid one-step green synthesis of gold and silver nanoparticles using fruit extract of Averrhoa bilimbi Linn. UV-Vis absorption spectroscopy was used to monitor the quantitative formation of gold and silver nanoparticles. The characteristics of the obtained gold and silver nanoparticles were studied using UV-Vis absorption spectroscopy (UV/Vis), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Energy-dispersive spectroscopy (EDX). UV/Vis spectrum showed Surface Plasmon Resonance (SPR) for both gold and silver nanoparticles at 540 and 420 nm. The EDX spectrum of the solution containing gold and silver nanoparticles confirmed the presence of elemental gold and silver signals. The average diameter of the prepared nanoparticles in solution was about 50-150 nm. Synthesized particles were either hexagonal or rhomboidal in shape. This synthesis approach of gold and silver nanoparticles is cost effective and can be widely used in biological systems. The effect of fruit extract and metal ion concentration was also studied.

“…In the 1650 cm –1 region, peaks were present, indicating C=C and C=O, as well as stretching of the primary amides, ketones, carboxylic acids, and aromatic compounds (Mazeika et al, 2016a; Jegatheesan et al, 2012; Socrates, 2001; Jiang et al, 2004; Chang Chien et al, 2007; Cantrell et al, 2012) associated with the organic phases. These peaks were present in all spectra of the residues, except that of MM fertilizer.…”

The joint use of analytical techniques helps us to better understand the characteristics and chemical processes that may influence the efficiency of fertilizers. Differential scanning calorimetry, X‐ray diffractometry, and Fourier transform infrared spectroscopy techniques are helpful in capturing the differences in compounds and mineral presence in fertilizers before and after application to the soil. Organomineral and inorganic fertilizers have different capacities to make P available in the soil. Different methods of organomineral fertilizer production result in different capacities to provide P, so that the granulation process resulted in lower P solubility than the granule mixture. Understanding the behavior of different organomineral phosphate fertilizers will help the delivery of available P to plants. We evaluated differences in the characteristics and P availability of granulated organomineral fertilizer (OG), an organomineral granule mixture (OM), and an inorganic granule mixture (MM) and their residues (OGr, OMr, and MMr, respectively) after four 35‐d cropping cycles. Soil‐available P content, X‐ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and soluble P content analyses of the fertilizers and residues were performed. The OM soil had higher available P content after the crops than those with OG and MM. The OGr had the highest total P, water‐soluble P, and P soluble in neutral ammonium citrate and water and a more intense DSC peak related to the remaining monoammonium phosphate than OMr and MMr, indicating that OG had the highest capacity to provide P over time. The XRD and FTIR analyses showed the predominance of aluminum phosphates and the possible formation of low‐solubility compounds in all residues. Differential scanning calorimetry showed a change in the characteristics of the organic matter of OG and OM after application, indicating that these fertilizers have different solubilities and capacities to make P available. The granulation process of OG results in lower capacity to provide P than the granule mixture used for OM. The joint use of several analytical techniques helps clarify fertilizers' characteristics and the chemical processes that influence their efficiency and may be helpful for improving the management and manufacture of organomineral phosphate fertilizers.
