Dielectric breakdown characteristics of a high current metal vapor plasma
(Elsevier, 1987)
Time- and spatially-resolved spectroscopy is used to study the early-time spectral features of the plasmas produced by high-current, capacitive discharges through thin silver films. Spectra are compared for several support ...
The microwave spectrum of argon-phosphorus trifluoride
(Elsevier, 1987-01-23)
The argon-PF3 complex has been prepared in a supersonic expansion of Ar (98%) and PF3 (2%). A Fourier-transform micro-wave spectrometer employing a Fabry-Perot cavity was used to assign 28 rotational transitions. The ...
Aminoglycoside antibiotics preferentially increase permeability in phosphoinositide-containing membranes: a study with carboxyfluorescein in liposomes
(Elsevier, 1987-08-07)
The rate of release from multilamellar liposomes of the fluoroscent probe carboxyfluorescein was determined as a measure of membrane permeability. Liposomes of phosphatidylcholine and different anionic phospholipids were ...
Synthesis and characterization of binuclear tantalum hydride complexes
(Elsevier, 1987)
Reduction of the quadruply-bridged (2Cl, 2H) tantalum(IV) dimer, Ta2Cl6 (PMe3)4H2 (2) with sodium amalgam in glyme or THF at 0[deg]C provides deep green Ta2Cl4(PMe3)4H2 (3) in 70% yield. Dimer 3 has a D2d Ta2Cl4(PMe3)4 ...
An in situ infrared study of the oxidation of sulfur dioxide on platinum electrodes
(Elsevier, 1987-10-09)
The thermodynamics of ammonium scheelites IV. Heat capacity of ammonium metaperiodate NH4IO4 from 8 to 324 K
(Elsevier, 1987-07)
The heat capacity of the scheelite salt ammonium metaperiodate, NH4IO4, was measured from 8 to 324 K using adiabatic calorimetry. The heat capacity against temperature curve shows an excess with a maximum around 200 K as ...
Determination of an empirical energy function for protein conformational analysis by energy embedding
(John Wiley & Sons, Inc., 1987-10)
It is quite easy to propose an empirical potential for conformational analysis such that given crystal structures lie near local minima. What is much more difficult, is to devise a function such that the native structure ...
The thermodynamics of ammonium scheelites V. Heat capacity of deuterated ammonium metaperiodate ND4IO4 from 8 to 329 K
(Elsevier, 1987-10)
The heat capacity of the scheelite salt: deuterated ammonium metaperiodate, ND4IO4, was measured from 8 to 329 K using adiabatic calorimetry. The heat capacity against temperature curve shows a broad maximum with a peak ...
Thermodynamics of copper sulfides III. Heat capacities and thermodynamic properties of Cu1.75S, Cu1.80S, and Cu1.85S from 5 to about 700 K
(Elsevier, 1987-12)
The heat capacities of Cu1.75S, Cu1.80S, and Cu1.85S have been measured by adiabatic-shield calorimetry from 5 to about 700 K. The heat-capacity curves show transitions near 312, 337, and 355 K in Cu1.75S and Cu1.80S and ...
The influence of a plane boundary on the thermophoretic force in the knudsen regime
(Elsevier, 1987-05)
The effect of a plane diffusely reflecting wall on the thermophoretic force acting on a particle in the Knudsen regime is investigated. A general expression for the force on a particle in a nonuniform gas is given and then ...
