PEG supported Cu–Mo mixed metal oxide (CuO–MoO3@PEG): A highly efficient catalyst for the enamination of pyrimidine dione and dimedone

F3‐functionalized nanoscale metal–organic frameworks for tumor‐targeting combined chemotherapy and chemodynamic therapy

“…The MIL‐101‐PLA‐PEG‐F3 obtained after polymer modification still showed good crystallinity, such as its characteristic diffraction peaks remain sharp, and new diffraction peaks appeared at 2 θ = 19.1° and 23.3°, corresponding to the (120) and (130) crystal planes of PEG in the polymer 38 . In addition, two small peaks near the angle of 27 belong to the low‐intensity diffraction peaks of PEG 39 . Compared with Alkyne‐PLA–PEG‐F3, after the surface modification of the nanoparticles, the intensity of each diffraction peak is weakened, and the peaks with low intensity are barely noticeable, but the main diffraction peaks can still be observed.…”

Role of nanohybrid NiO–Fe3O4 in enhancing the adsorptive performance of activated carbon synthesized from Yemeni-Khat leave in removal of Pb (II) and Hg (II) from aquatic systems

“…From the EDX data, the 0.2 KeV short signal is attributed to carbon [ [57] , [58] , [59] ], whereas the 0.60 KeV middle band is attributed to oxygen [ 58 ]. Iron is thought to be responsible for the bands that formed at 6.46 and 7.41 keV, while other signals that existed at 0.90, 7.50, and 8.20 keV are related to the presence of nickel [ [59] , [60] , [61] , [62] , [63] ]. These bands demonstrate that Ni–Fe oxides presented onto the surface of AC, supporting the successful formation of NF/AC nanocomposites.…”
