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. ...
Copper-induced expression, cloning, and regulatory studies of the plastocyanin gene from the cyanobacterium Synechocystis sp. PCC 6803
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-10)
Plastocyanin can be detected in Synechocystis sp. PCC 6803 when 3 μM copper is added to the growth medium, BG-11. The plastocyanin gene ( petE ) was cloned from a genomic λ EMBL 3 library by screening with the petE gene ...
Polymer membrane-based ion-, gas- and bio-selective potentiometric sensors
(Elsevier, 1993)
Recent progress in the design of new polymer membrane-based potentiometric ion-, gas- and bio-selective electrodes in chemistry laboratories at the University of Michigan (Ann Arbor) is reviewed. Emphasis is placed on ...
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 physical properties of N -substituted polyimides based on imidazole
(John Wiley & Sons, Inc., 1993-09)
AB-type monomers based on imidazole for the preparation of polyimides were synthesized by carrying out a substitution at the 1-position of 2-amino-4,5-dicyanoimidazole, followed by hydrolysis. Thus, pendant groups such as ...
Photoluminescence of exchange-coupled Mo3+ pairs in CsMgCl3
(IOP Publishing Ltd, 1992-01-13)
The high-resolution luminescence spectra of CsMgCl3 doped with Mo3+ contain bands that are very temperature-sensitive between 5 K and 2 K and that can be assigned to exchange-coupled Mo3+-V-Mo3+ pair centres (V=divalent ...
The effect of protonation on [Mn(IV)(μ 2 -O)] 2 complexes
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-01)
The series of complexes [Mn(IV)(X-SALPN)(μ 2 -O)] 2 , 1 : X=5-OCH 3 ; 2 : X=H; 3 : X=5-Cl; 4 : X=3,5-diCl; 5 : X=5-NO 2 , contain [Mn 2 O 2 ] 4+ cores with Mn-Mn separations of 2.7 Å. These molecules can be protonated to ...
