Abstract	In the current study, five different plants, Syzygium Cumini, Fagonia cretica, Acacia modesta, Withania coagulans, and Olea europaea aqueous extracts were prepared and applied against the anticancer and antibacterial activities. It was observed that O. Europaea extract shows the highest anticancer activity with cell viability of 21.5%. All the five plants extract was also used against the inhibition of Bacillus subtilis where O. Europaea extract shows a promising inhibitory activity of 3.2 cm followed by W. coagulans. Furthermore, W. coagulans was subjected to the process of column chromatography as a result a withanolide was isolated. The fast atom bombardment mass spectrometry (FAB-MS) and high resolution fast atom bombardment (HRFAB-MS) [M + 1] indicated molecular weight at m/z 453 and molecular formula C₂₈H₃₇O₅. The UV–Vis. spectrum shows absorbance at 210 nm suggesting the presence of conjugated system, and Fourier-transform infrared spectroscopy (FTIR) was recorded to explore the functional groups. Similarly, 1D and 2D NMR spectroscopy techniques such as ¹H, ¹³C NMR, correlation spectroscopy (COSY-45°), heteronuclear single quantum correlation (HSQC), heteronuclear multiple bond correlation (HMBC) and Nuclear Overhauser effect Spectroscopy (NOESY) techniques was carried out to determine the unknown natural product. The collective data of all these techniques established the structure of the unknown compound and recognized as a withanolide.

Abstract	In this study, microcrystalline cellulose (MCC) was modified to oxidized cellulose (OC), 6-deoxycellulose hydrazide and 6-deoxycellulose (N,N-diethyl)amine (MCC-Hyd and MCC-DEM) derivatives and employed as supporting material for the synthesis of copper nanoparticles (NPs). Copper ions from aqueous solution were adsorbed and then reduced to zero valent copper (ZVC) NPs using sodium borohydride on films of prepared derivatives. The characterization of prepared derivatives and Cu NPs embedded films was performed using Fourier Transform Infrared Spectroscopy, Elemental analysis, X-ray diffraction, Scanning Electron Microscopy, X-ray photoelectron spectroscopy and Nuclear Magnetic Resonance spectroscopy. Ultraviolet/Visible (UV–VIS) spectroscopy was performed for the degradation studies of 4-nitrophenol (4-NP) and various azo dyes viz. Congo Red, Methylene Blue, and Methyl orange. Results revealed that all the films showed degradation only in the presence of ZVC NPs. Oxidized cellulose, MCC-Hyd and MCC-DEM showed excellent degradation efficiencies (> 85%) in all the cases. Our findings revealed that MCC derivatives could be efficient and renewable candidates for removal of water pollutants in future.

Abstract	In this investigation, Pergularia tomentosa leaves were used as a promising source of bioproducts for the reduction of copper sulfate into copper oxide nanoparticles. The prepared nanoparticles were characterized using Fourier-transform infrared spectroscopy (FT-IR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission electron microscopy (TEM), and Thermogravimetric analysis (TGA). FI-IR showed the presence of hydroxyl, ester, and aromatic groups, which are characteristics of phenolics and other bioproducts. SEM features exhibited spherical and agglomerated particles. In EDX data, the peak at 1 Kev, is an index of metallic nanoparticles of copper. The signals related to C and O peaks indicated the presence of phytochemicals in the studied extract. The synthesized copper oxide nanoparticles had a face-centered cubic structure. The size of the nanoparticles varied from 1.7 to 15.2 nm. The adsorption capacity of methylene blue using copper oxide nanoparticles reached 93.2 mg/g (pH = 6, T = 22 °C, adsorbent dose = 0.0125 g). Additionally, methylene blue solution was completely decolorized after 2 min of reaction (pH = 6, 0.0057 mg NaBH₄, C ₀ = 10 mg/L, catalyst = 0.005 g). NOVELTY STATEMENT In this study, Pergularia tomentosa leaves were used, for the first time, as a biomaterial rich in bioproducts for the reduction of copper sulfate into copper oxide nanoparticles. The prepared particles act as promising materials for the decolorization of contaminated water via both adsorption and degradation processes.

Abstract	In this work, a superabsorbent polymer, sodium polyacrylate, also known as water ball (WB), loaded with Ni, Cu, and Ag zero-valent metal nanoparticles (MNPs) was applied for environmental remediation. WBs loaded with Ni, Cu, and Ag NPs were evaluated for their catalytic performance against the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) and decolorization of methyl orange (MO), Congo red (CR), and methylene blue (MB) dyes.

Abstract	Performance of polymer-based Au catalysis depends on the size of Au particles and the structure of polymer host materials. In the current studies, the carboxymethyl cellulose-chitosan (CMC-CH) sheet was synthesized by layering CMC on CH sheet, while CMC-CH-CBV 780 zeolite Y (CMC-CHZY) sheet was synthesized by coating the CMC layer on a sheet of CH-incorporated CBV 780 zeolite Y (ZY). The CMC-CH or CMC-CHZY sheets were individually immersed in Au(III) salt solution, which was converted to Au⁰ NPs by treating with NaBH₄ to synthesize Au/CMC-CH or Au/CMC-CHZY catalysts respectively. Both the synthesized Au catalyst activities were compared against the discoloration of methylene blue (MB) and Congo red (CR) dyes as well as the reduction of 4-nitrophenol (4-NP). It was revealed that Au/CMC-CHZY catalyst showed excellent catalytic performance against all the pollutants. Furthermore, the apparent rate constant kₐₚₚ (3.3 [Formula: see text] 10⁻¹ min⁻¹), of Au/CMC-CHZY catalyst was found higher against MB dye discoloration as compared to CR and 4-NP. It was also observed that MB discoloration followed pseudo-first-order while CR and 4-NP followed the zeroth-order kinetics. The catalyst alters the mechanism of a chemical reaction and so does the order of the reaction, therefore, observed different orders of reaction in the current study.
