Abstract Materials science, an interdisciplinary field of R & D, certainly benefits from the cooperation of engineers, chemists and physicists. An example is in the synthesis and applications development of organometallic polymers. Their structures are being optimized through employing different monomers, polymer…
Hepatocytes and fat-storing cells have been implicated in the production of collagen, under both normal and pathological conditions. In this study, short-term primary cultures of rat hepatocytes, maintained in a serum-free, hormonally defined medium without dexamethasone and cultured on a fibronectin-collagen type IV…

Abstract This paper reviews the literature of polymer blends containing low and high molar mass liquid crystals. Low molar mass liquid crystals have been used as plasticizers for thermoplastic polymers and in applications such as electrooptics, optical recording media, and membranes. High molar mass liquid crystalline…
Si molecular-beam epitaxy (MBE) on smooth Si(100) surfaces is shown to occur at room temperature. We demonstrate for the first time that Si deposition becomes amorphous after growth of a limiting epitaxial thickness (${\mathit{h}}_{\mathrm{epi}}$). ${\mathit{h}}_{\mathrm{epi}}$ is \ensuremath{\approxeq}10--30 \AA{} at…
This article —included on a long time ICCET Investigation Program— studies the mechanical resistances variation, to flexure, of the 1 X 1 X 6 cm mortar samples (1:3) made with high initial resistance cement and with several slags addition (cement/slag = 85/15 - 65/35 - 40/60 and 30/70) with high furnace slag and a fly…
The lithotype mainly used in the construction of the Cathedral of Seville is the calcarenite from Puerto de Santa f\/laria followed by the limestone from Espera. The primordial extrinsecal factor of deterioration is the atmospherical contamination, mainly sulphur oxides and smoke, within a humid environment. From both…
This updating review describes, from the conceptual standpoint, all the research works so far carried out at the IDIEM by the group in charge of Probabilistic Strength of Materials as well as research activities under way at present. This description considers three aspects. First, the general purposes of the commente…
This paper has adopted a theoretical viewpoint for studying Fracture Statistics in round bars subjected to torsion, and for determining the cumulative probabilities of fracture using Weibull's specific-risk function for materials that exhibit volume and surface brittleness. The use of the defined-functions method has…

The results of the structural, optical, and electrical characterization of , , and films grown by the successive ionic layer adsorption and reaction process are presented. Polycrystalline cubic and hexagonal films grown on glass and on indium‐tin oxide covered glass have mean crystallite sizes and , and and , respecti…

The mechanism of cell damage by ultrasound in combination with hematoporphyrin was studied. Mouse sarcoma 180 cell suspensions were exposed to ultrasound for up to 60 s in the presence and absence of hematoporphyrin, with and without active oxygen scavengers. The cell damage enhancement by hematoporphyrin was suppress…
Accurate values for the hydrodynamic transport properties of random dispersions of hard spheres have been determined by numerical simulation. The many-body hydrodynamic interactions are calculated from a multipole-moment expansion of the force density on the surface of the solid particles; the singular lubrication for…

Superplastic structural ceramics (Y‐TZP, Al 2 O 3 , Si 3 N 4 , and their composites) that can withstand biaxial stretching to large strains have been developed recently. Microstructural design of these ceramics first requires an ultrafine grain size that is stable against coarsening during sintering and deformation. A…
Single crystals in the lead magnesium niobate-lead titanate-(1−x) Pb(Mg1/3 Nb2/3)O3-(x) PbTiO3 solid solution system were grown using a flux growth technique. Crystals over the compositional range of 0.3 ≤ ′ ≤ 0.4 being near the rhombohedra1 (pseudo-cubic)-tetragonal morphotropic phase boundary were characterized. The…
