“…The XRD patterns of the synthesised AgNPs have been presented in Figure 5. Notable Bragg reflections were observed at 2h values of 38.10, 44.25, 64.55 and 77.20, indicating the (111), (200), (220) and (311) of the Face-Centered Cubic (FCC) AgNPs, respectively [44,45]. These results obviously showed that the AgNPs were composed of highly crystalline nanostructures.…”

This study aimed to report a one-pot, eco-friendly and room temperature procedure to prepare highly stable (at least 15 months) silver nanoparticles (AgNPs) using the aqueous leaf extract of Cordia myxa. The effects of different parameters, such as applied pH in the reaction mixture, amount of the leaf extract, silver ion concentrations, time of reaction and synthesis temperature, on the formation of NPs and their Surface Plasmon Resonance (SPR) spectra were studied. The characterisation of the prepared AgNPs was done using UV-Vis spectroscopy, Fourier Transform Infrared (FTIR), X-Ray Differentiation (XRD) and Transmission Electron Microscope (TEM) techniques. The shape of the synthesised AgNPs was spherical and it sized 3-10 nm with a face-centred cubic structure with SPR spectra at 410 nm. A possible reaction mechanism of AgNP formation by biomolecules of C. myxa was also introduced. The efficiency of the synthesised AgNPs as an excellent catalyst for the reduction of organic azo dyes using NaBH 4 was proved. Dose-dependent cytotoxic activity of the prepared AgNPs against SW480 and HCT116 human colon cancer cell lines was also shown using MTT assay. Furthermore, the Ferric-Reducing Antioxidant Power (FRAP) assay was utilised to confirm the antioxidant activity of NPs. Non-toxic reagents and low-cost synthesis were the main features that made these AgNPs more attractive for chemical/biomedical applications.

“…However, during the enlarged syntheses, reproducibility is critically important for the potential technological applications of GQDs. In continuation of our research work [27][28][29], in this work we have reported that the pyrolysis of citric acid was carried out which on further addition of sodium hydroxide for maintaining the pH produced GQDs. The effect of different pH on the formation of GQDs was studied in detail.…”

Graphene quantum dots (GQDs) as a new series of nanomaterials have drawn great attention in recent years owning to their unique properties. Here we report the single-step synthesis of GQDs using pyrolysis of citric acid which produced GQDs at different pH. The effect of different pH was studied in detail to optimize the conditions of the formation of GQDs. UV-Visible absorption and normalized fluorescence spectra were applied to analyze the optical properties of GQDs. The particle size distribution of the GQDs in case of varying pH was determined to optimize the synthesis conditions. The surface morphology and microstructures were studied by atomic force microscope (AFM).

Graphene is a ground-breaking two-dimensional (2D) material that possesses outstanding electrical, optical, thermal, and mechanical properties and that promises a new generation of devices. Despite all these, some applications require graphene-based materials with different characteristics, such as good solubility in organic solvents and a specific band gap to be dispersible in polymer nanocomposite matrix and applied as active layer, electron transport layer (ETL) or hole transport layer (HTL) in organic photovoltaics. Chemically modified graphene derivatives are studied, searching for better dispersions and even more properties for different applications. Most of the attention has been drawn to dispersions of graphene oxides or highly reduced graphene oxides. Therefore, this allows an opportunity to study the characteristics of materials with intermediate oxidation degrees and its applications.
