We present microscopic observations of the diffusion in water of micrometer-sized spheres confined between two walls. Deviations from the Stokes-Einstein law are observed, which for different bead diameters and different separations between the walls depend on a single dimensionless parameter. We compare numerical pre…

Abstract The crystal structure of Fe 4 Al 13 was refined using single crystal diffractometer data: Pearson symbol mC102, space group C 2/ m ; a = 15.492(2) Å, b = 8.078(2) Å, c = 12.471(1) Å, β = 107.69(1)°; R F = 0.053, R F ( w ) = 0.044 for 1127 reflections and 137 refined parameters. The coordination numbers of ato…

The growth of ${\mathrm{PbTiO}}_{3}$ films by a metalorganic chemical-vapor-deposition technique has resulted in three-dimensionally epitaxial heterostructures on various single-crystal substrates. These heterostructures consist of ${\mathrm{PbTiO}}_{3}$ films on the (001) surface of the single crystals: potassium tan…

This work has demonstrated the great influence that the specific surface of a Portland cement has on its qualification as a high or low resistance to sulfate ion attack - SIA, by means of the accelerated method ASTM C 452. For that purpose two Portland cements have been tested by means of that method. A Portland cemen…
Stones placates present a wide of problems that result in the fall of plates. One of the causes is the lack of adherence stone-mortar. We considered a study to determine the adherence between several cement mortars (1:3, 1:5, 1:7, 1:9 and a especial mortar prepared with latex) and stones (white granite, pink granites,…

The electrochemistry of polyaniline (PANi), which has been chemically synthesized and processed in a variety of ways into thin films, has been studied, and a comparison to those properties observed in thin electrochemically grown PANi films made. In this work, PANi via solution processing has been formed into thin fil…
