Abstract In this research paper, we report a clean and simple approach for the phytosynthesis of nanoparticles zero-valent iron (nZVI) through in situ reduction Fe 2+ to 0 using red cabbage extract. These nZVI were then loaded onto Ti/Mo-MOF nanostructure, resulting formation novel nZVI@Ti/Mo-MOF nanocomposite. To synthesize iron, utilized extract as reducing agent. Subsequently, synthesized incorporated into create The characterization biosynthesized nanocomposite was conducted UV–vis spectroscopy, FT-IR, XRD, XPS, FESEM, EDS. used sensitive peroxidase colorimetric sensing cholesterol. Under optimal conditions, cholesterol concentration range investigated from 1.0 nM 100.0 nM, which that show linear relationship with detection response. limit sensor is 6.24 nM. Furthermore, antioxidant properties antimicrobial activity its constituents against four bacterial strains well two fungal strains. Additionally, demonstrated superior compared other compounds paves way manufacturing innovation.

Abstract Through a facile chemical precipitation process, pure zinc oxide (ZnO) and various ratio of Mn-doped (Zn 1-x Mn x O) nanostructured materials were synthesized. The degradation an azo dye acid orange 2 (AO-2) solution under UV light was investigated using the synthesized as photocatalysts. XRD, FTIR, DLS, FESEM, EDS, PL, BET, magnetic, TGA UV–vis techniques used to elucidate structural, functional, particle, elemental, morphological, optical aspects catalysts. XRD FESEM analysis showed hexagonal ZnO structure spherical shape nano-photocatalyst, respectively. crystal sizes Zn O are 27.40–38.31 nm. band gap energy Zn1-xMnxO 2.53–3.10 eV. Under irradiation for 60 min, MZ-25 NPs demonstrated better (100.0%) AO-2 dye. effect factors such catalyst quantity, pH on rate removal investigated. After min irradiation, obtained ideal conditions (with loading 3 mgL −1 , 4). constant values sample determined be 0.0219 . scavenging test reveals that ∙O − ∙OH responsible photo-degradation

The cryopreservation of human spermatozoa is an integral part cryobiology, aiming to support the in-vitro fertilization. latter relies on availability as much possible reproductively active spermatozoa, whose number after thawing decreases due accompanied freezing injury and cytotoxicity cryoprotectants. An innovative option circumvent these obstacles make interface non-wettable, by coating it with rapeseed oil soot possessing intrinsic cryoprotective properties, delaying ice formation possibly providing identical rates intracellular dehydration extracellular crystallization. It may mean that this technique can reduce or avoid need harmful agents, but reach such a developmental stage, synergistic effect certified cryoprotectants cooling velocities efficiency soot-mediated sperm must be clarified. With intention address research gap, we reveal slow freezing/thawing distinct mixtures three (SpermFreeze™, CryoSperm™ DMSO) semen nine patients equalizes percent survived declines their curvilinear velocity. At instant (∼7-20 s) thawing, via specially-designed fabric-coated sheet metal cryoboxes, inclusion 10 % DMSO noxious, post-thaw motility reaches 74-100 independently solutes. These surprising findings are ascribed quasivitrified semen, complete ensures fraction matching from equilibrium phase diagram, eluding osmotic shocks paving path for future replacement classic vitrification.
