An exact analytic formula for the magnetostatic interaction energy of a three-dimensional array of ferromagnetic cubes is presented. The magnetization within each cube is assumed constant but varies in direction from cube to cube. From the expressions for the interaction energy, exact formulas for the effective magnet…
The self-diffusivity of Brownian hard spheres in a simple shear flow is studied by numerical simulation. Particle trajectories are calculated by Stokesian dynamics, with an accurate representation of the suspension hydrodynamics that includes both many-body interactions and lubrication. The simulations are of a monola…
Abstract Guided by the symmetry in a natural way, periodic potential surfaces partition the space in solid crystalline compounds. The arrangement of atoms, clusters and molecules obviously follows the (in general) curved shape of these ‘space partitioners’. In structures, the atoms therefore choose only a very limited…
The molecular architecture of the rabbit skeletal muscle aldolase (D-fructose-1,6-bisphosphate D-glyceraldehyde-3-phosphate-lyase, EC 4.1.2.13) tetramer has been determined to 2.7-A resolution. Solution of the three-dimensional structure of rabbit muscle aldolase utilized phase information from a single isomorphous Pt…
Abstract In condensed matter systems there are, in general, stresses at atomic level which are related to local incompatibilities. Only in perfect crystals in which all the atoms are equivalent such incompatibilities do not exist but they are present in ordered structures with non‐equivalent atoms and in any disordere…

Molecular-dynamics simulations have been carried out on a ``soft-sphere'' model for binary alloys quenched into supercooled and amorphous states. The main emphasis of the work is on the static and dynamic characterization of the glass transition. A comparison between molecular-dynamics data and the results of a self-c…
We have determined the three-dimensional structure of two crystal forms of an antilysozyme Fab-lysozyme complex by x-ray crystallography. The epitope on lysozyme consists of three sequentially separated subsites, including one long, nearly continuous, site from Gln-41 through Tyr-53 and one from Gly-67 through Pro-70.…
This paper reviews and analyzes the literature on thin carbon layers with emphasis on their use as protective overcoats for thin-film magnetic media. We discuss carbon as a material, its preparation as a thin film, and review and evaluate various techniques for characterizing its thin-film properties.
We computed the specific heat of site lattice animals with nearest-neighbor attractive interaction for various animal sizes N, with N up to 80, on the simple-cubic lattice. For fixed N, the specific heat as a function of the temperature exhibits a peak at a temperature ${T}_{m}$(N) depending on N. As N increases, this…
Using angular momentum representation a method is proposed that allows the systematic construction of a generalized Landau-de Gennes elastic free energy of liquid crystals, in powers of a symmetric and traceless tensor order parameter, polarization field, of external fields and all respective derivatives. By this meth…
With the use of differential thermal analysis, X‐ray diffraction, and transmission electron microscopic techniques, we showed that γ‐Al 2 O 3 type spinel phase is solely responsible for the 980°C exotherm in the kaolinite‐to‐mullite reaction series. Transmission electron microscopic characterization indicated that the…
A complex new magnetic refrigerant, suitable for the ideal Ericsson cycle, has been investigated. Above ∼15 K it is necessary to use ferromagnets as a magnetic refrigerant. However, temperature variation for the magnetic entropy change in a homogeneous ferromagnet is not suitable for the Ericsson cycle. The present pa…
ABSTRACT Evaluation of the effect of pressure on the temperature of interlayer water loss (dehydration) by smectites under diagenetic conditions indicates that smectites are stable as hydrated phases in the deep subsurface. Hydraulic and differential pressure conditions affect dehydration differently. Smectites under…

A model is presented of the steps involved in the manufacturing process of semicrystal line thermoplastic matrix composites. The model relates the temperature and pressure ap plied during processing to a) the flow of the matrix into the fiber tow, b) the formation of contact and bond between adjacent plies, and c) the…
Type I procollagen was purified from the medium of cultured human fibroblasts incubated with 14C-labeled amino acids, the NH2-terminal propeptides were cleaved with procollagen N-proteinase, and the resulting pC-collagen was isolated by gel filtration chromatography. pC-collagen did not assemble into fibrils or large…
Abstract The size of the minor phase in an immiscible polymer blend can have a significant effect on properties such as the impact strength. Few studies, however, have quantitatively considered the parameters controlling the size of the dispersed phase. In this paper, light and scanning electron microscopy have been u…
