Sulfite-sensitive solvent/polymeric-membrane electrode based on bis(diethyldithiocarbamato)mercury(II)
(Elsevier, 1989)
A new solvent/polymeric-membrane electrode which exhibits significant potentiometric response toward sulfite ion in the 1 x 10-6-1 x 10-3 M range is described. The membrane is prepared by incorporation of neutral ...
Characterization of cytosolic forms of CTP: choline-phosphate cytidylyltransferase in lung, isolated alveolar type II cells, A549 cell and Hep G2 cells
(Elsevier, 1989-12-18)
The subcellular forms of cytidylyltransferase (EC 2.7.7.15) in rat lung, rat liver, Hep G2 cells, A549 cells and alveolar Type II cells from adult rats were separated by glycerol density centrifugation. Cytosol prepared ...
Are cationic [eta]3-allyl complexes general precursors to metallacyclobutanes? Synthesis and structure of [mu]-chloro-bis[([eta]3-allyl)-2,2'-bipyridyldicarbonylmolybdenum(II)] tetrafluoroborate
(Elsevier, 1984-08-28)
Silver tetrafluoroborate reacts with Cl(bipy)(CO)2([eta]3-C3H5)Mo in CH2Cl2 to give the dimeric cation, ([mu]-Cl)[(bipy)(CO)2([eta]3-C3H5)Mo]2+, isolated as the crystalline BF4- salt with CH2Cl2 of solvation (5). Complex ...
Expert system for interpretation of the infrared spectra of environmental mixtures
(Elsevier, 1988)
A program for the identification of the principal components of mixtures through interpretation of the infrared mixture spectrum (IntIRpret) was developed. This program, which was developed as a preliminary screening tool ...
1,4-Additions of the highly functionalized copper reagents RCu(CN)ZnI [middle dot] 2 BFP3 to trisubstituted enones. A new BF3 promoted cyclization reaction
(Elsevier, 1988)
The new copper reagents RCu(CN)Zn I [middle dot] 2 BF3 1 containing various functional groups like esters, cyanides, chlorides or enoates react with [beta], [beta]'- disubstituted enones to afford the Michael adducts 4-7 ...
The thermodynamics of the divalent metal fluorides. III. Heat capacity of the fast ion conductor SrSnF4 from 6 to 344 K
(Elsevier, 1989-07)
The heat capacity of the fast ion conductor SrSnF4 was measured by adiabatic calorimetry from 6 T/K 19F spin-lattice relaxation time T1 occurs. Standard molar thermodynamic functions are given at selected temperatures from ...
Mutarotation of optically active poly( cis -5-ethyl- D -proline)
(John Wiley & Sons, Inc., 1983-06)
The mutarotation between form I and form II of poly( cis -5-ethyl- D -proline) has been experimentally realized. A number of hydrogen-bond-forming solvents have been found effective in initiating the mutarotational process. ...
Vibrational spectra, assignments and normal coordinate analyses for crystalline zirconium tetrachloride and tetrabromide
(Elsevier, 1981)
Raman and far-IR spectra have been obtained of crystalline ZrCl4 and ZrBr4. The observed frequencies have been interpreted on the basis of the C2h symmetry of the Bravais unit cell and have been subjected to a normal ...
Is cytochrome aa3 from thermus thermophilus a single subunit oxidase?
(Elsevier, 1983)
A reliable procedure has been developed for the purification of the cytochrome c1aa3 complex from the plasma membrane of T. thermophilus. The ratios heme C:heme A:Fe:C were found to be 1:2:3:2 confirming previous results, ...
CPS K 843 Radiation-induced crosslinking: Effect on structure of polyethylene
(Steinkopff-Verlag; Steinkopff ; Springer Science+Business Media, 1985-02)
Branched polyethylene irradiated (0–400 Mrad) with a Co 60 source at room temperature under vacuum was studied by density, wide- and small-angle X-ray scattering (WAXS and SAXS) measurements. The radiation effects on the ...
