    Description: La absorción y pérdida del sulfito en el camarón reviste gran importancia en su manejo post-cosecha y procesamiento industrial, por cuanto el residual de sulfito puede dar una medida de la protección que presenta el camarón contra la aparición de la melanosis. Se tomaron ejemplares de camarón y se sometieron a un tratamiento en solución de MBS al 8 % empleando diferentes tiempos de inmersión, determinándose los residuales de sulfito en el producto obtenido en cada caso. Adicionalmente, los camarones tratados durante cinco minutos se colocaron en contenedores plásticos con hielo en proporción 1:1, los que fueron colocados en una cámara de refrigeración a una temperatura entre 7 y 10 °C durante siete días. Se determinaron los residuales cada día con el objetivo de cuantificar las pérdidas que se producen durante el almacenamiento en hielo. Posteriormente se obtuvieron las curvas de absorción y pérdida de MBS y se determinaron los modelos matemáticos que explican dichos procesos. Se observó que la mayor absorción se produce en el primer minuto de inmersión. En el proceso de pérdida se conoció que a los seis días de almacenamiento en hielo, el residual de sulfito había mermado en un 93 %.
    Description: The absorption and loss of the sulfhite in the shrimp has great importance in their post-crop handling and industrial prosecution, since the residual of sulfhite can give a measure of the protection that presents the shrimp against the appearance of the melanosis. Shrimps were taken and underwent to a treatment in solution of MBS to 8% using different times of immersion, being determined the residual of sulfhite in the product obtained in each case. Additionally, the shrimps tried during five minutes were placed in plastic containers with ice in proportion 1:1, those that were placed in a refrigeration camera to a temperature between 7 and 10 °C during seven days. The residual ones were determined every day with the objective of quantifying the losses that take place during the storage in ice. Later the curves of absorption and loss of MBS were obtained and the mathematical models were determined that explain this processes. It was observed that the biggest absorption takes place in the first minute of immersion. In the process of loss it was known that to the six days of storage in ice, the residual of sulfhite had shrunk in 93%.

    Notes: The fabrication and lasing characteristics of a 1.5-μm distributed feedback laser with a butt-coupled tunable integrated resonator are described. An additional modulation of the distributed feedback laser spectrum introduced by the external cavity is clearly demonstrated. Optical bistability has been observed in the power versus tuning current characteristic. The device has a limited continuous tuning range of 4.2 A(ring). Tuning current change allows for the selection of compound cavity mode and one of the distributed feedback laser modes, while maintaining single-mode operation. Linewidth reduction due to the integrated cavity is clearly demonstrated, and linewidths 〈10 MHz have been obtained.

    Notes: The microstucture of metastable C49-TiSi2 was studied by high-resolution transmission electron microscopy in a bilayer thin film of Ti and Si annealed at 700 °C. Large grains (300–400 nm) of C49-TiSi2 phase with high density of stacking faults on (010) planes were observed. A preferred orientation among the C49-TiSi2 grains was identified, and the grains were aligned along the [010] with slight misorientation. The diffraction pattern from the metastable TiSi2 showed continuous streaks superimposed by discrete spots along hk0 reciprocal lattice rows, indicating the presence of polytypism. Lattice imaging of polytypic TiSi2 has been obtained and it showed that the structure is nonperiodic and one dimensionally disordered due to the stacking faults. The finding of metastable TiSi2 associated with polytypism suggests that its structure could be conveniently represented by various stackings of atomic planes along the [010] direction. An atomic model is proposed to explain the origin of polytypism. It is shown that the arrangement of atoms in C49-TiSi2 structure has four equivalent positions.

    Notes: Recent studies found that the (Pt/Co/Pt) trilayers can be used as a unit in combination with nonmagnetic or magnetic layer, X (X=Pd, Ag, Cu, and Ni), to enhance the perpendicular magnetic anisotropy of the films, reduce the Curie temperature, and alter the magneto-optical properties. The effects of intercalating Cr into Pd/Co multilayers on the magnetic and magneto-optical properties are studied in this article. The perpendicular magnetic anisotropy Ku and the coercivity Hc of the system decrease rapidly with increasing the Cr thickness (XCr) up to 0.4 nm, and change slightly when Cr thickness further increases. The dependence of the coercivity Hc on the Cr thickness, which obeys the law: Hc (XCr)=XCr−2.66, indicates that the magnetization reversal is controlled by domain wall moving, mainly due to the interface roughness. Large decrease of the Kerr rotation θk of the Pd/Cr/Co multilayers compared with pure Pd/Co multilayers is also found in the wavelength ranging from 200 to 800 nm. As it is well known, the large anisotropy and Kerr rotation in Pd/Co system are mainly caused by the polarization of Pd atoms due to nearby Co atoms. As the intercalating of Cr layer between Pd and Co layer, the average polarization of Pd atoms will be reduced largely. As a matter of fact, the Cr atoms can also be polarized by nearby Co atoms, which, however, seems to take a minor effect on the anisotropy and Kerr rotation of the system. © 2001 American Institute of Physics.

    Notes: It has been recently reported that the redistribution of dopant during titanium silicide formation enhances the grain growth of polycrystalline silicon at a temperature lower than it normally occurs. The mechanism which is responsible for the enhanced grain growth has been proposed to be dopant diffusion induced grain-boundary migration. We have carried out a detailed study to clarify the mechanism. The results show that the effect of phosphorus dopant alone has a small influence on the grain growth of polycrystalline silicon around 900 °C. However, much enhanced grain growth of polycrystalline silicon accompanied by titanium silicide formation was observed at 700 °C in medium doped and heavily doped conditions as compared to those without silicide formation. On the other hand, no enhanced grain growth was observed in lightly doped and undoped situations regardless of titanium silicide formation. By correlating these observations with depth profiling of dopant distribution, it is concluded that the formation of titanium silicide serves as a sink for the out-diffusion of dopant. The out-diffusion of dopant, preferentially through grain boundaries, leads to a reduction of 30%–50% of dopant from the implanted levels. The depletion of dopant induces grain boundaries to migrate, and therefore enhances the grain growth.

    Notes: Alignment of undoped polycrystalline silicon deposited on 〈100〉 single-crystal silicon is known to occur for temperatures higher than 1000 °C. In this paper we provide evidence of a greatly enhanced epitaxy occurring in the polycrystalline silicon film after arsenic ion implantation, which amorphizes the surface layer of this film, followed by rapid thermal processing. The significantly enhanced epitaxy over that of undoped polycrystalline silicon is attributed to the mechanisms of solid phase epitaxial growth of the amorphized surface layer and alignment and realignment and coalescence, which are thought to be enhanced by arsenic segregation to the film grain boundaries and its interface with the silicon substrate via grain boundary diffusion. During this rapid epitaxy the arsenic atoms distribute themselves throughout the film, presumably with a considerable fraction occupying substitutional sites and electrically active.
