Abstract Biological and green synthesis of nanomaterial is a superior choice over chemical physical methods due to nanoscale attributes implanted in chemistry matrix, have sparked lot interest for their potential uses variety sectors. This research investigates the growing relevance nanocomposites manufactured using ecologically friendly, technologies. The transition correlates with worldwide drive environmentally sound procedures, limiting use traditional harsh synthetic techniques. Herein, manganese was decorated on ZnO NPs via reducing agent Withania- extract confirmed by UV-spectrophotometry highest peak at 1:2 ratio precursors, having lower bandgap energy (3.3 eV). XRD showed sharp peaks confirms formation nanoparticles, particle size range 11–14 nm. SEM amorphous tetragonal structure while EDX spectroscopy presence Zn Mn all composition. Green synthesized Mn-decorated ZnO-NPs screened against bacterial strains exhibited excellent antimicrobial activities gram-negative gram-positive bacteria. To check further, applicability nanocomposites, photocatalytic activity toxic water pollutants (methylene blue (MB) dye) were also investigated results that 53.8% degradation MB done successfully. Furthermore, installation synthesizing plant matrix optimizes antibacterial characteristics, antioxidant biodegradability, helping build sustainable nanomaterial. work, explains how biologically friendly Mn-doped can help reduce environmental impact packaging materials. Based these findings, it determined derived from biological resources should be produced wide scale eradicate contaminants through degradation.

Herein, we compare the degradation of binary dye mixture containing methyl orange (MO) and methylene blue (MB)in respect to them separately in presence newly synthesized (chemical co-precipitation method) bimetallic optical material Fe-CdO NPs with greater surface area. were characterized via XRD, SEM, EDX, FTIR, UV visible PL. XRD patterns indicate that have FCC structure, Fm3m space group lattice constant value 4.6900A0. Absorption spectra studied region. EDX signify elemental composition its percentage value. FTIR helps understand occurrence functional groups chemical bonding. After irradiation light for 130 min observed 90.78 % [K = 0.0161 min−1, T50 43.04 min] only MB 87.28 0.0135 51.33 mixture. Similarly, noticed 93.44 0.0188 36.86 MO 88.29 0.0142 48.80 We also exhibited effective antioxidant activity scavenging vitro DPPH (removal percentages 50.41 %) assay. Based on obtained findings, could act as a promising drug development deliver low-cost, clean drinking water without toxic dyes.

Abstract Stachys maritima is a species of plant belonging to the Lamiaceae, commonly known as common sea lavender. The extraction S. involves drying aerial parts, grinding them into powder, followed by with methanol. ST‐CQDs ( carbon quantum dots) were synthesized from extract via pyrolysis. An optimal synthesis condition 7 hours pyrolysis was determined yield high absorption in visible‐UV range. Characterization techniques such UV‐visible spectroscopy and TEM (Transmission Electron Microscopy) confirmed spherical homogeneous nature dots. methanol exhibited strong antioxidant activity DPPH (2,2‐Diphenyl‐1‐picrylhydrazyl) IC 50 value 0.114±0.001 mg/mL. Similarly, showed properties 0.69±0.03 Moreover, demonstrated antimicrobial against E. coli ATCC 25922 aureus 25923, effective MIC values 25 mg/mL 6.25 mg/mL, respectively. However, did not show effects tested microorganisms 25922, K. pneumoniae 13883, C. albicans 10231). Molecular docking simulations suggested that compounds derived (such 9,12,15‐octadecatrienoic acid palmitic acid) could interact effectively TNF‐α (Tumor Necrosis Factor Alpha), indicating potential anti‐inflammatory properties. This study highlights possesses potent activities, exhibit similar demonstrate pathogens. also suggest plant.

Abstract The use of efficacious and cost‐effective pesticides (OP OC) has undoubtedly proven to be a blessing baron because these are safeguarding the world from food insecurity. Unfortunately, their presence in aquatic bodies brings about an upsurge water pollution. Amazingly, photocatalytic degradation approach utilizing biogenic nanoparticles (BNPs) is trendy state‐of‐the‐art been established sustainable methodology for complete mineralization contaminants into harmless molecules. Thus, this work holistically explores BNPs OP OC. Based on review, it was found that least amount time needed less than 5 minutes, while maximum efficiency >80 %. dominant radicals participating ⋅OH O 2 ⋅ radical dominance enhanced by oxygenated functional groups present entities employed biosynthesis BNPs. data fits pseudo‐first‐order Langmuir isotherm models (R > 0.9), which indicates main adsorption mechanisms involved during electron‐hole pair formation physisorption monolayer at surface can sustain % approximately cycles reusable up 8 cycles. It also revealed plants constitute 80 engaged BNP synthesis. Ultimately, offers novel avenues future research hotspots might accelerate agricultural wastewater management practices.
