Abstract The primary objective of this study was to create and analyze a new type LaFeO 3 /methylcellulose/multi-walled carbon nanotubes-NiCu 2 O 4 /Zn nanocomposite, called LFO/MC/MWCNT-NCO/Z, which has multiple functions. Structural investigation using field emission scanning electron microscopy showed that the nanoparticles (40–50 nm) were evenly distributed throughout suggesting they successfully incorporated without any clumping. FTIR research verified existence functional groups facilitate electrostatic interactions with contaminants, hence strengthening catalytic performance improving adsorption efficiency. BET analysis revealed significantly high specific surface area 72.61 m /g, greatly enhances its ability adsorb substances. nanocomposite demonstrated removal efficiency in (74.55%), photocatalysis (68.19%), sonocatalysis (91.22%) procedures, highlighting potential for effectively removing bisphenol A as organic pollutants. synthesized LFO/MC/MWCNT-NCO/Z shows great eliminating contaminants from water solutions. This offers sustainable way address pollution protect human health environment.

Abstract In this research Manganese-substitution impact on linear and nonlinear (NL) optical properties of Aluminum-doped ZnO (AlZnO) Nanoparticles (NPs) are investigated. Utilizing measured data reflectance acquired from the DRS, higher-order NL characteristics provided NPs examined. The maximum quantity susceptibility χ 3 is to be around 3.945 × 10 −10 esu at wavelength λ = 520 nm 7.467 −11 530 for AlZnO Manganese-substituted Zinc-Oxide (Mn-also) NPs, particle sizes 14−67 11−54 nm, consecutively. Consequently, synthesis method (sol–gel) which used in work concluded a decrease size different behavior especially UV spectral regions during substitution with Manganese comparison AlZnO. This decrement assures that crystallite induces decline . obtained parameters red shifted substitution. Also, absorption coefficient ( β c (m/W)) enhanced range. (m/W)), Mn-AlZnO determined (at 250 nm) 2.24 −18 (m/W) 5.76 −15 respectively.
