Mesoporous crystalline metal oxides [PDF]
, 2009 Mesoporous monocrystalline metal oxides (e.g. Co₃O₄, Cr₂O₃, NiO, CeO₂, In₂O₃ and WO₃) templated by SBA-15 or KIT-6 were synthesised successfully by using a simple solvent-free approach, the so-called solid-liquid method, which was the principal ...

Zeitschrift für Naturforschung B, 2006 The cyclization of a ribose-derived pentenose oxime with various halogen electrophiles showed bromine to be the most effective reagent, leading to 80% of L-lyxo/D-ribo-pyrroline N-oxides in an 84:16 diastereomeric ratio. In order to explore the scope of this facile process, several other γ,δ - unsaturated oximes were submitted to this reaction ...

1,4-Di-N-oxide quinoxaline-2-carboxamide: Cyclic voltammetry and relationship between electrochemical behavior, structure and anti-tuberculosis activity [PDF]
Electrochimica Acta, 2011 To gain insight into the mechanism of action, the redox properties of 37 quinoxaline-2-carboxamide 1,4-di-N-oxides with varying degrees of anti-tuberculosis activity were studied in dimethylformamide (DMF) using cyclic voltammetry and first derivative cyclic voltammetry. For all compounds studied, electrochemical reduction in DMF is consistent with the

Mixed Oxides for Photo-electrochemical Applications
Chemical Engineering Transactions, 2016 The photoexcitation of an n-type photo-anode and a p-type photo-cathode provides electrons and holes in photo-electrochemical processes. Depending on the use of photosensitive material as anode, cathode or both, different photo-electrochemical (PEC ...
