A large (40 mm ϕ) composite membrane with mesoporous silica nanotubes (F127MST) was coated with a thin carbon layer (1–2 graphene sheets) by carrying out chemical vapor deposition (CVD) using acetylene, and the obtained carbon-coated F127MST (C/F1

An acetylcholinesterase-immobilized sensor unit was successfully prepared by encapsulating the enzyme within hybrid mesoporous silica membranes (F127-MST). Through a novel combination with tetracyanoquinodimethane, both acetylcholine and organophosph

Lipase encapsulation in 12 highly ordered mesoporous silica monoliths (HOMs) with different pore diameters (3-8 nm) and pore structures (2D and 3D mesostructures) was successfully achieved without leaching of the enzyme from the enzyme-HOM composite.

The ethylation of biphenyl (BP) with ethene was examined over dealuminated H-mordenite (MOR; SiO 2 /Al 2 O 3 = 206). The ethylation occurred non-shape-selectively, and gave a mixture of ethylbiphenyls (EBPs), diethylbiphenyls (DEBPs), and higher ethy

Liquid-phase alkylation of biphenyl (BP) was studied over large-pore zeolites. Selective formation of the least bulky products, 4,4′-diisopropylbiphenyl (4,4′-DIPB) occurred only in the isopropylation of BP over one- or two-dimensional zeolites,

Three different examples have shown that nanoporous alumina membranes serve as ideal templates for the formation of nanostructured materials and also as a support of those materials in composites. The unique properties of such membranes (transparency

Palladium-catalyzed aryloxycarbonylation of aryl bromides and iodides show contrastive reactivities with respect to the kind of phenoxides. The carbonylation of bromides with hindered potassium phenoxides in benzene gives ester products in high yield
