Complexes of tetracyanobiimidazole.4.dimers of Cu(I)
(Elsevier, 1984-08-15)
In this paper we described dimeric complexes of Cu(I) with 4,4',5,5'-tetracyano-2,2'-biimidazole (H2Tcbiim). These compounds contain the dianion (Tcbiim2-) acting as a quadridentate bridge betwee Cu(I) ions in combinations ...
Complexes of tetracynobiimidazole. 3. Platinum and palladium species
(Elsevier, 1984-07-01)
In this paper we describe monomeric complexes of Pd(II) and Pt(II) with 4,4',5,5'-tetracyano-2,2'-biimidazole (H2Tcbiim). These compounds always contain the dianion (Tcbiim=) in accord with the greater acidity expected for ...
Effect of low-dose irradiation on the surface properties of poly[(trifluoroethoxy)(telomer fluoro alkoxy)phosphazene]
(Elsevier, 1984-10)
The effect of low-dose ultraviolet and 3, irradiation on the surface and bulk properties of poly[(trifluoroethoxy)(telomer fluoro alkoxy)phosphazene], was found to initially result in an increased side chain mobility ...
Production of 232 Pa from thorium
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1984-03)
A procedure is described for the accelerator production of 232 Pa and its isolation in radiochemically pure form, suitable for isotope tracing of protactinium/thorium chemical separations.
Intermediate and high-mass ion beams from a 10-cm Duopigatron
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-06)
Experimental studies of a 10-cm Duopigatron as a source of argon, krypton, and xenon ion beams are reported. Source plasma instabilities are examined, and the mass dependence of oscillation frequencies and instability onset ...
Graphical analysis of interactions between oxidation-reduction sites in two site oxidation-reduction protein
(Elsevier, 1984-01)
Many enzymes that catalyze electron-transfer reaction contain multiple oxidation-reduction centers (sites). The oxidation-reduction potential of one site as well as the kinetics of electron transfer through this site may ...
The reaction of pyrite with diphenyl ether
(Elsevier, 1984)
Diphenyl ether is converted into diphenyl sulfide (largely), dibenzofuran, phenoxybiphenyls, diphenoxybiphenyls, and several other sulfur- containing compounds by reaction with pyrite at 350-360[deg].
Gold-titania interactions: Temperature dependence of surface area and crystallinity of TiO2 and gold dispersion
(Elsevier, 1984-05)
The influence of temperature on the BET surface area, crystallinity, and anatase/rutile phase transformation of blank TiO2 and Au/TiO2 catalysts is studied. Presence of gold delays the recrystallization of anatase and the ...
Reactivity of propylene oxides towards deoxycytidine and identification of reaction products
(Elsevier, 1984-07)
Deoxycytidine was reacted with four epoxides of varying alkylating rates: propylene oxide, glycidol, epichlorohydrin and trichloropropylene oxide. Deoxycytidine was chosen to compare the reactivities of these epoxides as ...
