The chloride requirement for photosynthetic oxygen evolution. Analysis of the effects of chloride and other anions on amine inhibition of the oxygen-evolving complex
(Elsevier, 1984-09-27)
In the presence of Cl-, the severity of ammonia-induced inhibition of photosynthetic oxygen evolution is attenuated in spinach thylakoid membranes (Sandusky, P.O. and Yocum, C.F. (1983) FEBS Lett. 162, 339-343). A further ...
The microwave spectrum and structure of the neon-phosphorus trifluoride complex
(Elsevier, 1990-08-17)
Symmetric top spectra were observed for the 20Ne[middle dot]PF3 and 22Ne[middle dot]PF3 van der Waals dimers using a Fourier-transform microwave spectrometer. The center-of-mass distance between Ne and PF3 is 3.373(3) A. ...
An inorganic functional group approach to the systematic synthesis and reactivity studies of binuclear Mo/S and Mo/S/O complexes
(Elsevier, 1989)
A number of general reactions, based on molybdenum-coordinated sulphido or polysulphido ligands, can account for the synthesis of many members of the [Mo2V(S)n(S2)6-n]2-, [Mo2V(O)(S)n(S2)5-n]2- and [Mo2V(O)2(S)n(S2)4-n]2- ...
Thermophysics of metal alkanoates VII. Heat capacities and thermodynamic properties of potassium n-butanoate
(Elsevier, 1987-02)
The subambient heat-capacity curve of potassium n-butanoate as determined by adiabatic equilibrium calorimetry is characterized by a "bifurcated" transition whose "peaks" occur at 123.85 and 142.3 K. The corresponding (Cp, ...
The total synthesis of the water mold sex hormone oogoniol
(Elsevier, 1989)
The water mold sex hormone oogoniol (1a) has been synthesized from adrenosterone in 18 steps in 7.0% overall yield. The crucial step introduces the stereochemistry at C-15 and C-20 through a highly efficient 1,4-addition ...
Hot-atom chemistry
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1990-09)
Research in the chemical effects of the nuclear transformations during the past 50 years is reviewed.
Hadamard transform photothermal deflection desitometry of electrophretically blotted proteins
(Elsevier, 1990)
Hadamard transform spatial multiplexing techniques are applied to laser densitometry in order to prevent the photo-induced degradation of sensitive materials. Photochemical and thermal degradations can often occur in point ...
Synthesis and polymerization of ( E , E )-[6.2](9,10)anthracenophane-1,5-diene
(John Wiley & Sons, Inc., 1989-01-30)
The title compound has been synthesized by dimerization of a substituted p -xylylene, generated via a 1,8-Hofmann elimination. Several unique isomers of this dimer are also obtained. The title diene can be polymerized ...
Automated integration of monolith-based protein separation with on-plate digestion for mass spectrometric analysis of esophageal adenocarcinoma human epithelial samples
(WILEY-VCH Verlag, 2006-09)
A unique approach of automating the integration of monolithic capillary HPLC-based protein separation and on-plate digestion for subsequent MALDI-MS analysis has been developed. All liquid-handling procedures were performed ...
The stereochemistry of ethylene-1,2-d2 epoxidation over silver catalysts
(Elsevier, 1980-10)
The stereochemistry of the catalytic epoxidation of cis-ethylene-1,2-d2 to ethylene oxide over four unsupported and two supported silver catalysts as well as over Ag2O and AgO was studied. Variations of the stereochemistry ...
