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...

VO2+ and its complexes with ethylenediamine (en), acetylacetonate (acac), 2, 2’-bipyridine(bpy) ligands, immobilized within nanoreactors of Al-MCM-41 designated as VO2+/Al-MCM-41 or VOL2/Al-MCM-41, were prepared and characterized by X-ray powder diffraction (XRD), FT-IR, BET nitrogen adsorption-desorption and chemical analysis techniques. VO2+/Al-MCM-41 and VOL2/Al-MCM-41 were found to catalyze...

[Structure: see text] The versatility of supramolecular chemistry has been exploited in constructing nanovalves based on mesoporous silica MCM-41 and the mutual recognition between secondary dialkylammonium ions and dibenzo[24]crown-8 (DB24C8). Naphthalene-containing dialkylammonium threads were tethered to the MCM-41, followed by loading with coumarin 460 and capping with DB24C8. Controlled re...

We present neutron scattering measurements of the excitations of liquid He confined in MCM-41 at wave vectors 0.35 Å<q<2.15 Å . MCM-41 is a uniform porous material consisting of cylindrical pores, here of 32 Å diameter. The location and phase of He in the pores was well characterized by pressure isotherms and by exploratory neutron scattering measurements. The first 60% of He entering the MCM-4...
