To investigate responses of Glycyrrhiza glabra var. glabra and G. glabra var. glandulifera to molybdenum and salicylic acid, we measured four stress biochemical parameters: anthocyanin, nitric acid, glycyrrhizic acid and peroxidase activity in callus tissues. Callus tissues obtained from seedlings root cultures were treated by 60 mg. l-1 molybdenum and 5 µM salicylic acid alone or together for...

The interactions of two-dimensional vanadium oxide and molybdenum oxide overlayers with the surface hydroxyls of an alumina support were examined with 'H MAS NMR spectroscopy. The measurements demonstrated that these surface metal oxide overlayers are homogeneously distributed over the alumina surface and essentially titrate all the accessible surface hydroxyls at monolayer coverage. The invest...

The reaction of MoO(3) with 2-(3-pyrid-yl)benzoimidazole and water in the presence of MnSO(4)·5H(2)O at 453 K under hydro-thermal conditions afforded the title compound, {(C(12)H(11)N(2))[Mo(4)O(13)]}(n), in which infinite molybdenum oxide anionic chains are charge-balanced by diprotonated 2-(3-pyrid-yl)benzoimidazole (H(2)3-PBIM(2+)) cations. Eight [MoO(6)] octa-hedra are edge-shared, forming ...
