DOI: 10.1002/sscp.202200026 This cover picture shows the applicability of Mobil catalytic material number 4 modified magnetite nano-composites (MCM-41@Fe3O4) in magnetic solid phase extraction (MSPE). MCM-41@Fe3O4 as MSPE was first added to sample solution NSAIDs containing diclofenac, ketoprofen, and mefenamic acid. After 5 min incubation, can be separated using a field. Further, supernatant c...

To take advantage of the synergistic effects of Pt and Zr, a kind of Zr-doped, Pt-modified aluminide coating has been prepared by a hybrid process, first electroplating a Pt layer and then co-depositing Zr and Al elements by an above-the-pack process. The microstructure and isothermal oxidation behavior of the coating has been studied, using a Pt-modified aluminide coating as a reference. Resul...

MCM-41 and Zn-MCM-41 were successfully synthesized using hydrothermal impregnation methods. The silica mesoporous was confirmed by characterizing the material XRD, SEM-EDS, BET-BJH analyses. XRD results showed three main peaks at angles of 2θ = 2.40° (100), 3.87° (200), 4.49° (210), which are characteristics materials with hexagonal structures. SEM analysis that surface morphology Zn-modified f...

a r t i c l e i n f o Based on previous reports, showing that zirconium alloying to Ti 1 − x Al x N hard coatings can increase their thermal stability, we study in detail the interaction of bias potential and Al content on structure, hardness, thermal stability, and oxidation resistance of arc evaporated Ti 1 − x − y Al x Zr y N hard coatings. For moderate Al-contents, Ti 0.49 Al 0.44 Zr 0.07 N...

incorporation of [fe(bipy)cl4][bipy.h] (1) (where bipy is 2,2′-bipyridine) in the molecular sieves of the type lta, nay and mesoporous al-mcm-41 by using a “ship in a bottle synthesis” approach was investigated. [fe(bipy)cl4][bipy.h] was successfullyincorporated in the channels ofmesoporousal-mcm-41, and the product was characterized by x-ray diffraction, ftir and bet analysis. it was fou...
