Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was l ...
The syntheses of new C8-carbasugars and -aminocyclitols related to miglitol and voglibose are described. The key step involves the ring closing metathesis of 1,9-dienes derived from D-mannitol. Chemical transformations of the newly created double bond of t ...
The Diels-Alder adduct 3 of 2,2'-ethylidenebis(3,5-dimethylfuran) to diethyl (E,E)-4-oxohepta-2,5-diene-1,7-dioate was converted into meso-(1R,2R,4R,4aR,5S,7S,8S,8aS,9aS,10aS)- 1,8-bis(acetoxymethyl)- 1,3,4,5,6,7,8,8a,9,9a-decahydro-2,4,5,7,10 -pentamethyl ...
A high-reflectance GaInP/GaAs distributed Bragg reflector (DBR) was grown by chemical beam epitaxy (CBE). The mirror consists of 40 pairs of alternating layers and was designed for a centre wavelength of 980 nm, resulting in a total thickness of 5.8 mum. H ...
