Laser-driven micro-explosive bonding of aluminium films to copper and silicon
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-06)
Laser explosive microfabrication was used to bond micrometre-thick aluminium films to both copper and silicon substrates. Bonding was observed in both systems for laser intensities greater than about 1 × 10 9 W cm −2 and ...
Characterization of a transport system for anionic amino acids in human fibroblast lysosomes
(Elsevier, 1989-12-28)
-Aspartate and -glutamate are transported into human fibroblast lysosomes by a single, low Km, Na+-independent transport system, which has been provisionally named lysosomal system d. This system resembles the Na+-dependent ...
Purification, properties, and oxygen reactivity of p-hydroxybenzoate hydroxylase from Pseudomonas aeruginosa
(Elsevier, 1989-12-21)
The monooxygenase, p-hydroxybenzoate hydroxylase (4-hydroxybenzoate, NADPH: oxygen oxidoreductase (3-hydroxylating), EC 1.14.13.2) has been isolated and purified from Pseudomonas aeruginosa. The reaction catalysed is linked ...
Chemical characterization of biodegradative threonine dehydratases from two enteric bacteria
(Elsevier, 1982-08-23)
Some chemical properties of the purified biodegredative threonine dehydratases (-threonine hydro-lyase (deaminating), EC 4.2.1.16) from Escherichia coli and Salmonella typhimurium are described. The overall amino acid ...
Observation of coupled quasi-two-dimensional electronic excitations in tilted magnetic fields
(Elsevier, 1988)
We report on a magneto-Raman scattering investigation of free and donor-bound electrons in GaAs/AlxGa1-xAs quantum wells. For fields perpendicular to the layers, the spectra show intersubband transitions of photoexcited ...
On Green's functions, propagators, and sturmians for the nonrelativistic coulomb problem
(John Wiley & Sons, Inc., 1984-03-01)
Recent progress in the mathematical physics and quantum chemistry of Coulomb Green's functions is summarized. Analogy with the defining relation for the Green's function has led to a finite model for the Fermi contact ...
Heat capacity and thermodynamic properties of ditungsten carbide, W2C1-x, from 10 to 1000 K
(Elsevier, 1988-06-30)
Thermodynamic properties of tungsten carbide, W2C0.833, have been derived from heat capacities measured by adiabatic calorimetry in the range 10-1000 K on a sample rich in this phase. The standard entropy of W2C0.833 was ...
An ab initio study of the structure and torsional modes of the H2SO4 molecule
(Elsevier, 1982-05)
Ab initio calculations at the STO--3G and 4--31G levels have been carried out for the H2SO4 molecule as a function of the pair of twist angles of the H---O bonds about the respective O---S bonds. Values for the remaining ...
