چکیده

We report the green chemistry reduction approach method for synthesis of Manganese Oxide nanoparticles (MnO NPs), Copper (CuO NPs) and Manganese-doped (Mn-doped CuO Nps). Aqueous extract from seeds was used as reducing capping agents. The detailed crystal structure analysis investigated; crystallite size, crystallinity, morphological index, x-ray density, bulk specific surface area, porosity, Lorentz factor, polarization factor other parameters were calculated. Simple EDX mapping reveals presence Mn, Cu, O C. FTIR to determine bond length a nanocomposite. In visible have higher optical absorption, with bandgaps varying 1.79 (MnO), 2.18 eV (CuO) 1.72 CuO). After 90 min, photodegradation rate Mn-doped nanocatalysts 93.73 % while using smaller amount catalyst (0.1 g) at pH 7. pseudo-first-order MB photocatalytic decomposition kinetic model has high correlation coefficient value (R2 > 0.95). It found that NPs efficiency can be potential photocatalysts industrial dye degradation. HIGHLIGHTS Green Cu by Bambusa Characterized via XRD (crystal structure), UV-Vis Diffuse Reflectance spectra (UV-DRS), FT-IR (bond length), FESEM-EDS Photocatalytic degradation organic methylene blue GRAPHICAL ABSTRACT

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
