One part of a split root system of wheat seedlings received full nutrient solution with15N-nitrate, the other received an identical solution with unlabelled nitrate. Appearance of labelled amino compounds was measured in the xylem sap exuding from roots not supplied directly with15N-nitrate after removal of the15N-nitrate-fed roots. This material indicates… (More)
The title compound, lithium tris[dioxidovanadium(V)] bis[trioxidotellurium(IV)], contains chains of edge-sharing distorted VO(6) octahedra. The pyramidal TeO(3) groups crosslink the chains into sheets. Finally, an Li(+) cation adopting an unusual capped trigonal-bipyramidal LiO(6) geometry bridges the layers to complete a three-dimensional structure.
The polyhedral building blocks of the layered inorganic network in the mixed-valence title compound, (NH4)(V(IV)O2)(V(V)O2)(TeO3), are vertex-sharing V(V)O4 tetra-hedra, distorted V(IV)O6 octa-hedra and TeO3 pyramids, which are linked by V-O-V and V-O-Te bonds, forming double layers lying parallel to (100). The presumed Te(IV) lone-pairs of electrons appear… (More)
The hydrothermal syntheses and single-crystal structures of BaTe3O7 and BaTe4O9 are reported. These closely related new phases, which can be regarded as the n = 3 and 4 members of the BaTenO2n+1 family, are built up from infinite, tubular, columns of Te/O polyhedra (6 ring loops for BaTe3O7 and 8 ring loops for BaTe4O9) with barium cations completing the… (More)
The title compound, lithium trimanganese bis[trioxoselenate(IV)] hexakis[hydrogentrioxoselenate(IV)], is built up from a vertex-sharing network of distorted Mn(III)O(6) octahedra, SeO(3) and HSeO(3) pyramids and unusual Li(OH)(6) octahedra, resulting in a dense three-dimensional structure. Mn, Li and one Se atom have site symmetries of -1, -3, and 3,… (More)
Hydrothermally prepared SrMn(SeO(3))(2) contains infinite chains of vertex-sharing irregular MnO(5+1) polyhedra [mean Mn-O 2.226(3)A], which are fused into layers via pyramidal SeO(3) groups [mean Se-O 1.698(3)A]. Nine-coordinate Sr(2+) cations [mean Sr-O 2.715(4)A] complete the layered structure.
The percentage composition, fatty acids and oxidation stability was obtained from “peanut mayonnaise” in comparison with commercial mayonnaise and sunflower oil. “Peanut mayonnaise” showed better chemical quality than commercial mayonnaise.
