Texture Development in YBa 2 Cu 3 O x by Hot Extrusion and Hot-Pressing
(Blackwell Publishing Ltd, 1987-12)
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 ...
A stochastic theory of grain growth
(Elsevier, 1987-07)
A stochastic theory of normal grain growth is proposed. The model is based on the concept that the migration of kinks and ledges should cause a Brownian motion of the grain boundary. This motion results in a drift of the ...
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 ...
