Nitrate Species

The electrochemical oxidation of thorium in either nitric acid/tri-n-butyl phosphate (TBP) or dinitrogen tetroxide/ethyl acetate/acetonitrile media gives rise to non-aqueous solutions of thorium(IV) nitrate species. The only neutral adduct which could be obtained from HNO3/TBP solution was Th(NO3)4•8dmso (dmso = dimethylsulphoxide). Salts of [Th(NO3)6]2− with Et4N+, [(bpyH)3NO3]2+, and [(phenH)3NO3]2+ (bpy = 2,2′-bipyridine; phen = 1,10-phenanthroline) were also prepared by this route. Solutions in N2O4/EtOAc/CH3CN yield Th(NO3)4, and neutral adducts with dmso, bpy, phen, Ph3PO, and pyridine-N-oxide.

Anodic Electrocatalyst

The anodes of IrxSi1-xO2/Ti (x= 0.2~1) were prepared by thermal decomposition of non-aqueous solution of iridium chloride (IrCl3) and tetraethoxysilane (TEOS). The microstructure and surface morphology of the IrxSi1-xO2 coatings were characterized by XRD and SEM. A large amount of fine crystallites aggregated on the surface of coatings to form a porous structure with a range of particle size of 15-18nm. The particle size decreased firstly and then increased with increase of silica content and received a minimum value at the Ir0.6Si0.4O2 coatings. The electrochemical characterization determined by cyclic voltammetry (CV) indicated that the IrxSi1-xO2 coating with x=0.6 showed a maximum surface charge (q). The experiments of electrochemical synthesis of N2O5 from N2O4 in nitric acid indicated that the Ir0.6Si0.4O2 coating had the best electrocatalytic performance.

Schumacher and Halbsguth first demonstrated ectodesmata as pores or channels in the epidermal cell walls in haustoria of Cuscuta odorata L. by light microscopy in tissues fixed in a sublimate fixative (30% ethyl alcohol, 30 ml:glacial acetic acid, 10 ml: 65% nitric acid, 1 ml: 40% formaldehyde, 5 ml: oxalic acid, 2 g: mecuric chloride to saturation 2-3 g). Other workers have published electron micrographs of structures transversing the outer epidermal cell in thin sections of plant leaves that have been interpreted as ectodesmata. Such structures are evident following treatment with Hg++ or Ag+ salts and are only rarely observed by electron microscopy. If ectodesmata exist without such treatment, and are not artefacts, they would afford natural pathways of entry for applied foliar solutions and plant viruses.
