The electronic structure of ${\mathrm{La}}_{2\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Sr}}_{\mathit{x}}$${\mathrm{NiO}}_{4}$ is studied by use of photoemission spectroscopy, bremsstrahlung-isochromat spectroscopy (BIS), and electron-energy-loss spectroscopy. Quantitative analyses are made on the valence-band and N…
We have studied the organization of the cytoskeleton in both unstimulated and stimulated cultured chromaffin cells, as well as its relationship with their secretory process by exocytosis. We found the spatial heterogeneity in the intensity of cortical rhodamine-phalloidin staining within a cell. The overall staining p…
An investigation is carried out on the feasibility of calculating the diffuse scattering from computer simulations of crystals containing substitutional and displacement disorder which have hitherto been used in conjunction with optical transform methods to aid in the interpretation of observed X-ray diffraction patte…

Langmuir monolayers of n-eicosyl sulfate were shown to influence the nucleation of BaSO<sub>4</sub> grown from supersaturated solutions (S = 30) at room temperature (293 K). Thin, elongated single crystalline plates were nucleated with the (100) face parallel to the plane of the monolayer. Partial matching…
We prove the existence of a first-order, entropy-driven demixing transition in a simple lattice model for a hard-core mixture. The existence of this transition follows from the fact that this lattice model can be mapped onto an Ising model with nearest-neighbor interactions for which the phase behavior is known. The s…
Trypsin and acid phosphatase-containing silica sol-gel glasses were obtained by mixing a solution of an enzyme with polyethylene glycol (PEG) 6000 and tetramethoxy orthosilicate at room temperature, followed by gelation and drying. Activity of the immobilized trypsin toward small substrates, such as N-benzoyl-L-argini…
Vacuum microelectronics is a new interdisciplinary field utilizing the mechanism of electron emission into a vacuum for devices requiring bulk and surface micromachining. By fabricating arrays of conductive or semiconductive structures that are either gated or ungated, a multitude of devices can be formed that utilize…

Ceramic varistors based on ZnO with lead zinc borosilicate glass instead of Bi 2 O 3 were prepared. The effect of sintering conditions on the electrical properties was studied by sintering samples at various temperatures and cooling them at different rates. The sample sintered at 1250°C for 1 h, then furnace cooled, p…
A selective discussion of electron attachment to molecules is presented with emphasis on recent studies of SF6, carried out with a novel laser photoelectron attachment (LPA) method in the energy range 0·1-170 me V with an effective energy resolution around 0·1 me V near threshold.

π-Stacking interactions in the nearly parallel 3,6-bis(2-pyridyl)-pyridazine (dppn) ligands probably account for the distortion of the planar Cu4 unit in 1 from a square to a rhombus. Each Cu atom is surrounded in a tetrahedral fashion by two N atoms from pyridine and two N atoms from pyridazine units; the chelate rin…
