“…The higher the pH, the faster the ZnO nanoparticles are formed 50) . This is related to previous research by Alahdal et al (2022), where the production of ZnO nanoparticles at the same pH 12 had optimal growth and greater absorbance compared to pH 6. However, the absorbance of ZnO nanoparticles decreased slightly when approaching pH 14 due to the low single dispersion in the formation of ZnO nanoparticles.…”

“…However, the absorbance of ZnO nanoparticles decreased slightly when approaching pH 14 due to the low single dispersion in the formation of ZnO nanoparticles. Meanwhile, in acidic medium or lower than pH 6, ZnO nanoparticles cannot be formed because they are only formed in neutral and base medium 51) . The strong absorbance of all ZnO films produced by green synthesis is in the 300 nm to 370 nm ultraviolet wavelength region.…”

In this study, the zinc oxide (ZnO) films have been prepared via the green-synthesis method with rind extract of red watermelon (Citrullus lanatus) as bio-stabilizer, at various acidity (pH) conditions. The ZnO films were prepared as thin films by spin-coating colloidal ZnO onto a glass substrate. The physical properties of ZnO films were characterized using UV-Vis spectrophotometer, XRD, SEM/EDX, and FTIR. The photocatalytic activity of ZnO films was evaluated systematically in the degradation process of methylene blue (MB). The sample prepared at pH 12 possesses the highest purities and exhibits the maximum degradation percentage of 94.61%, with a reaction rate constant of 0.019 min -1 . The efficiency of the ZnO photocatalyst has a strong correlation with the pH value in the synthesis process. Based on the results of this study, ZnO films prepared via green synthesis using Citrullus lanatus show an effective photocatalytic activity in degradation of MB, so that it could be developed in the photocatalytic process of water purification.

“…XRD patterns were performed using a Lab X, SHIMADZU XRD-6100 instrument (Japan). The instrument was equipped with a rotation anode operating using copper-filtered Kα radiation at 40 kV , and 30 mA. The size of nanoparticles was measured by using dynamic light scattering (DLS), a digital correlation system (Malvern2008-V 2.3 (Zetasizer)-Hellma, GmbH, and U.K.).…”

Understanding the intermolecular interactions between antibiotic drugs and hemoglobin is crucial in biological systems. The current study aimed to investigate the preparation of chitosan/polysorbate-80/tripolyphosphate (CS-PS/TPP) nanocomposite as a potential drug carrier for Ciprofloxacin-HCl drug (CFX), intended for controlled release formulation and further used to interact with bovine hemoglobin. Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis−differential thermal analysis (TGA-DTA), scanning electron microscopy (SEM), dynamic light scattering (DLS), and X-ray diffraction analyses were used to characterize the CS-PS/TPP nanocomposite and its CFX-loaded nanocomposite. The second series of biophysical properties were performed on the Ciprofloxacin-loaded CS-PS/TPP (NCFX) for interaction with bovine hemoglobin (BHb). The interactions of (CFX and NCFX) with redox protein hemoglobin were investigated for the first time through a series of in vitro experimental techniques to provide comprehensive knowledge of the drug−protein binding interactions. Additionally, the effect of inclusion of PS-80 on the CFX-BHb interaction was also studied at different concentrations using fluorescence spectroscopy, ultraviolet−visible (UV−Vis) spectroscopy, and circular dichroism (CD) under physiological conditions. The binding process of CFX and NCFX was spontaneous, and the fluorescence of BHb was quenched due to the static mechanism formation of the (CFX/BHb) and (NCFX/BHb) complexes. Thermodynamic parameters ΔG, ΔH, and ΔS at various temperatures indicate that the hydrogen bonding and van der Waals forces play a major role in the CFX-BHb association.

“…For these reasons, various modern conventional methods have been used to detect NB and Cr(VI) from polluted aquatic environments, notably UV–vis spectrometry, electrochemical technique, chromatography, and luminescence. Among these methods, fluorescence detection is thought to be the most effective due to its remarkable sensitivity and affordable cost. − In this context, there was a pressing need to create novel nanomaterials that could detect Pb(II), As(III), Cr(VI), and NB in aqueous mediums. Presently, a number of recent studies have been conducted by fluorescence detection on the basis of mixed-ligand-based robust cadmium(II)-frameworks, amine-decorated multifunctional luminescent metal–organic frameworks, transition metal coordination polymers based on bent carboxylate and flexible spacer ligands, pillar-bilayer cadmium(II) frameworks, etc.…”

Herein, [Nd(NO 3 ) 3 (H 2 pzdca)] n (MA-1) was synthesized from a reaction of 2,3-pyrazinedicarboxylic acid [H 2 Pzdca] as an organic linker with salt of Nd(III) under solvothermal conditions. The detailed structural analysis for crystals was performed utilizing single-crystal X-ray diffraction (SCXRD). After that, the neodymium-based coordination polymer (MA-1) crystal was directly generated upon the surface of functionalized carbon nanotubes (F-CNTs) through bonds or affinity between F-CNTs and MA-1 via the solvothermal approach. Meanwhile, the existence of F-CNTs does not affect the production of MA-1 crystals. FT-IR, PXRD, SEM, TEM, and SCXRD studies were used to characterize the crystalline material, MA-1 and MA-
