Chemoselective acylation for the synthesis of model compounds of polynucleotide analogs
(Wiley Subscription Services, Inc., A Wiley Company, 1986-06)
No Abstract.
Relativistically parameterized extended Huckel calculations. 10. Lanthanide trihalides
(Elsevier, 1986-09-01)
The REX relativistically parameterized extended Huckel method is used to study the electronic structure of lanthanide trihalide molecules. All valence orbitals are described in terms of double-zeta Slater functions, with ...
Redistribution of Aluminum Ions During Processing of Sialon Ceramics
(Blackwell Publishing Ltd, 1986-08)
Effects of Triton X-100 concentration and incubation temperature on carboxyfluorescein release from multilamellar liposomes
(Elsevier, 1986-07-24)
Carboxyfluorescein is the most commonly used probe to measure the rate of release of vesicle contents. The validity of the data obtained by this method depends on obtaining an end point based on the complete release of the ...
Membrane effects of aminoglycoside antibiotics measured in liposomes containing the fluorescent probe, 1-anilino-8-naphthalene sulfonate
(Elsevier, 1986-11-06)
The mechanism of membrane disturbance by aminoglycoside antibiotics was investigated in liposomes containing the fluorescent probe, 1-anilino-8-naphthalene sulfonate (ANS). Liposomes of PC and different anionic phospholipids ...
A gas-jet system for the study of short-lived, light fission products
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1986-04)
For the study of short-lived fission products, a gas jet system has been set up in a beam port of the Ford Nuclear Reactor at the University of Michigan. The system consists of a target chamber joined to three polyethylene ...
Electron microdiffraction study of bimetallic Ru---Au/MgO catalysts
(Elsevier, 1986-08)
A microdiffraction study of bimetallic Ru---Au/MgO catalysts is carried out in order to discriminate between the random adsorption versus atomic ordering model proposed for the structure of bimetallic clusters. The ...
The microstructure of bimetallic Ru---Cu/SiO2 catalysts: A chemisorption and analytical electron microscopy study
(Elsevier, 1986-08)
Supported bimetallic Ru---Cu/SiO2 catalysts are characterized by transmission electron microscopy, energy dispersive X-ray spectroscopy, electron microdiffraction, and chemisorption. Metal particles up to 4 nm in diameter ...
Infrared spectroscopic study of NO reduction by H2 on supported gold catalysts
(Elsevier, 1986-11)
In situ Fourier transform infrared spectroscopy is used to study the reduction of NO by H2 on Au/SiO2 and Au/MgO catalysts. On these catalysts, large differences in selectivity toward N2 formation had been found depending ...
The influence of hydrazine reduction on metal dispersion and support morphology in bimetallic Ru---Au/MgO catalysts
(Elsevier, 1986-03)
The influence of hydrazine reduction on metal dispersion, particle size distribution, and support morphology was investigated for a series of bimetallic Ru-Au/MgO catalysts. The catalysts were prepared by impregnation of ...
