An elemental metal can dissolve at kink sites at low everpotentials producing no new interfacial area. When an ideal solid solution alloy undergoes selective dissolution, this situation is not possible owing to atomic‐scale disorder. Dissolution of the less noble constituent can proceed only by injection of regions of…

Article Probenpräparation für die Transmissionselektronenmikroskopie: Verläßliche Methode für Querschnitte und brüchige Materialien/ Specimen Preparation for Transmission Electron Microscopy: Reliable Method for Cross-Sections and Brittle Materials was published on October 1, 1993 in the journal Practical Metallograph…
The rheological behaviour of lyotropic lamellar phases is studied as a function of the membrane repeating distance. The steady-state rheology is described as a consequence of the so-called orientation diagram described previously. Three distinct regions of different orientations are described, which are separated by t…
Detailed Raman studies of the optical phonons in high-quality single-crystal ${\mathrm{PbTiO}}_{3}$ indicate that the mode energies and symmetry assignments in the literature [G. Burns and B. Scott, Phys. Rev. B 7, 3088 (1973)] must be revised. In this study, all k\ensuremath{\simeq}0 optical-phonon modes are directly…
This paper extends the Gaussian model of Li and Kardar [Phys. Rev. Lett. 67, 3275 (1991)]. When applied self-consistently to density fluctuations of a hard-sphere fluid, it is shown that the model gives the Percus-Yevick theory. With the addition of an attractive tail potential, the mean spherical approximation is obt…
Using a cell-dynamical system (CDS) to model the separation of phases, we present the results of large-scale simulations of spinodal decomposition in 3-space of a symmetric binary alloy and incompressible binary fluid at critical quench. Our main results are (1) the reliable determination of the asymptotic or the almo…

Extended x-ray-absorption fine structure and x-ray-absorption near-edge structure spectra at both the Zr and Y K edge have been obtained at 10 K and room temperature for solid ${\mathrm{ZrO}}_{2}$-${\mathrm{Y}}_{2}$${\mathrm{O}}_{3}$ solutions. Zr has very different local structures in the tetragonal and cubic solid s…

Three crystal structures, representing two distinct conformational states, of the mammalian catalytic subunit of cAMP-dependent protein kinase were solved using molecular replacement methods starting from the refined structure of the recombinant catalytic subunit ternary complex (Zheng, J., et al., 1993a, Biochemistry…
Water-soluble iron(III) porphyrin and ferrihemoproteins (methemoglobin, metmyoglobin, oxidized cytochrome c, and catalase) associate with NO to yield the nitric oxide adducts. The equilibrium constants for association of ferrihemoproteins and NO are 1 order of magnitude larger than that of the water-soluble iron(III)…
