Di- and triheteronuclear metal cluster anions containing transition metals
(Elsevier, 1984-03-01)
Homogeneous enzyme-linked assays mediated by enzyme antibodies; a new approach to electrode-based immunoassays
(Elsevier, 1984)
A new homogeneous enzyme--immunoassay system is described. The assay employs an ammonia-liberating enzyme covalenty coupled to protein antigens along with two antibodies. An anti-enzyme antibody inhibits the enzyme. However, ...
Electronegativity equalization and the electronic structure of polyhedral clusters of main-group atoms
(John Wiley & Sons, Inc., 1984-01)
The concept of the equalization of atomic electronegativities accompanving molecule formation is applied to a study of the electronic structure of polyhedral clusters of main-group atoms such as Ge, Sn, Pb, Tl, and Bi. ...
A gas-solid-phase microchemical method for the synthesis of acetyl hypofluorite
(Elsevier, 1984-04)
The useful electrophilic fluorinating agent, acetyl hypofluorite, was obtained by passing F2 diluted in N2 through columns containing complexes of alkali metal acetates with acetic acid. Acetyl hypofluorite obtained from ...
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 ...
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].
