Microcalorimetric studies of electrolyte mixtures: HCl-KCl and HCl-CaCl2. Application of Pitzers model
(Thermochimica Acta, 1999)
Heats of mixing of two concentrated isomolal aqueous electrolyte solutions have been measured using a flow-mix microcalorimetric method to determine the thermodynamic properties of the mixed solutions. Systems HCl-KCl and ...
Ageing of Cu-Cr powders produced by rotating electrode process (REP)
(Journal of Materials Science Letters, 1998)
Transition metal complexes with thiosemicarbazide-based ligands. XXXIX. [Benzoylacetone 3-methylisothiosemicarbazonato(2)-O,N-1,N-4](pyridine-N)nickel(II)
(Acta Crystallographica. Section C: Crystal Structure Communications, 1999)
The square-planar title complex of formula [Ni(C12H13N3OS)(C6H5N)] or [Ni(L)(py)] (L is the dianion of the O,N,N-terdentate benzoylacetone S-methylisothio-semicarbazone ligand and py is pyridine) has structural characteristics ...
Spectrophotometric studies of the influence of organic solvents and substituents on some Schiff bases
(Spectroscopy Letters, 1998)
The effect of the substituents, solvent polarities and hydrogen ion concentration on the electronic structure and UV/VIS absorption spectra of some Schiff bases, derivatives of N-(R-benzylidene)benzidine (R = o-NO2 and ...
Transition metal complexes with thiosemicarbazide-based ligands. 33. [4-(2-diphenylphosphino-alpha-ethoxybenzyl-P)-3-methyl-1-salicylidene-isothiosemicarbazido-N-1,N-4,O]nickel(II)
(Acta Crystallographica. Section C: Crystal Structure Communications, 1998)
The title compound, [Ni(C30H28N3O2PS)], is the first example of a transition metal complex involving a thiosemicarbazide-based tetradentate ligand with a P atom in its coordination sphere. The Ni atom in the complex has a ...
Rotational analysis of the B-2 Sigma(+)-X-2 Sigma(+) bands of (CO+)-C-12-O-18
(Spectroscopy Letters, 1998)
The emission spectrum of the B(2)Sigma(+) - X(2)Sigma(+) (First Negative) system of the molecular ion (CO+)-C-12-O-18 have been photographed at a resolution sufficient to observe the spin splitting of the lines with N GT ...
Transition metal complexes with pyrazole-derived ligands. X. [Zn(CH3COO)(2)L-2]center dot-2MeOH (L=3-amino-5-phenylpyrazole)
(Acta Crystallographica. Section C: Crystal Structure Communications, 1999)
Monocrystals of the title complex, bis(acetato-O)bis(3-amino-5-phenylpyrazole-N-2)zinc(II) dimethanol solvate, [Zn(C2H3 O-2)(2)(C9H9N3)(2)] . 2CH(4)O, were obtained by crystallization from a methanolic solution of ...
An analysis of burnup reactivity credit for reactor RA spent fuel storage
(Nuclear Engineering and Design, 1998)
The need for increasing the spent fuel storage capacity has led to the development of validated methods for assessing the reactivity effects associated with fuel burnup. This paper gives an overview of the criticality ...
Thermodynamics of cadmium halide complex formation in acetamide - Calcium nitrate tetrahydrate melt
(Journal of Molecular Liquids, 1999)
The complex formation between cadmium(II) ions and chloride and bromide ions in the melt of 0.8CH(3)CONH(2)-0.2Ca(NO3)(2). 4H(2)O has been studied at six temperatures between 30 and 80 degrees C. The formation constants ...
