In this post-new-normal era, the public prioritizes preventive measures over curing, which is a constructive approach to staying healthy. study, an innovative antimicrobial membrane material has been developed, showcasing promising potential for various applications. The metal-doped silica nanoparticles (Ag, Cu, and Co) were incorporated into cellulose acetate (CA) polymer-based nanofiber using electrospinning technique. metal doped silanol network of nanoparticles. fabricated membranes underwent detailed characterization wide range techniques including PXRD, FTIR, Raman, SEM, TEM, TGA, tensile testing. These analyses provided compelling evidence confirming successful incorporation cellulose-based nanofibers. band gap energies CA mats lie below 3.00 eV, that they are visible light active. trimetallic nanohybrid exhibited lowest energy 2.84 proving self-sterilizing ability mats. DPPH assay further confirmed best radical scavenging activity by mat (91.77 ± 0.88%). was assessed bacterial ATCC strains

Coupling TiO2 with various elements could enhance its photocatalytic activity. In this study, an innovative ultrasound-assisted sol–gel method was used to synthesize TiO2/Ag(x%) by varying Ag–support mass (x = 9.3, 17.1, and 23.6%), followed calcination at 450 °C for 30 min. The aim demonstrate that Ag compositing improves photoactivity under visible light (>400 nm). synthesized photocatalysts were assessed their effectiveness in the degradation mineralization of Methylene Blue (MB) Acid Orange 7 (AO7) using lamps emitting range 400–800 nm. Characterization prepared performed Raman spectroscopy, SEM/EDS, pHpzc, UV–visible spectroscopy. spectroscopy confirmed predominance anatase phase all photocatalysts. photodegradation efficiencies selected dyes, MB AO7, reached 99% (pH 6) 95% 3) after 180 min irradiation, respectively. best performance two dyes observed TiO2/Ag9.3%, showing optimal kinetics doping concentration. improved TiO2/Ag composite is due a decrease recombination rate electron/hole (e−/h+) band gap from 3.13 2.49 eV. both about 9.3%, indicating presence refractory by-products resist complete degradation. Under UVA obtained. This study confirms potential as high-performance cost-effective photocatalyst solar environmental remediation, highlighting role silver extending absorption into region improving charge separation.

Abstract The current supply of clean water is not keeping pace with the growing global population’s needs. This situation necessitates reuse freshwater through treatment for antibacterial and dye removal. study developed a green synthesis technique to produce silver nanoparticle-diatomite (AgNP-D) nanocomposite applications against E. coli S. aureus , as well photodegradation methylene blue (MB). Silver nanoparticles (AgNPs) were synthesized using soybean stalk extract impregnated into surface pores diatomite, forming AgNP-D nanocomposite. was characterized UV-Visible Spectroscopy, FTIR Particle Size Analysis, X-Ray Diffraction (XRD). analysis confirmed characteristic peak AgNPs at 446 nm. size indicated nanoparticle sizes in range 24.4-78.8 impregnation diatomite structure by XRD, 2-theta values 37.88°(111), 44.16°(200), 64.24°(220), 77.34°(311). Antibacterial testing demonstrated effectiveness inhibiting bacterial growth, minimum inhibitory concentration (MIC) 256 μg/mL >256 . process successfully degraded 99.98% (100 ppm) colorless leucomethylene within one minute.
