  • Patent number: 7841015
    Abstract: A method is described for determining a dopant concentration on a surface and/or in layer region lying close to the surface of a semiconductor sample using an atomic force microscope, whose leaf-spring tip is brought into contact with the semiconductor sample, forming a Schottky barrier, wherein an electric alternating potential is applied between the spring-leaf tip and the semiconductor sample in the region of the Schottky barrier in such a way that a space charge region inside the semiconductor sample defining the three-dimensional extension of the Schottky barrier is excited and begins to oscillate within the confines of its spatial extension, said oscillations are transmitted to the leaf-spring, are detected and form the basis for determining the dopant concentration.

  • Patent number: 7838805
    Abstract: Preform heating device able to perform a precise and strongly localised heating of the preforms before the blow moulding phase of the plastic bottle or container production process. This device has an innovative construction configuration, thus allowing high efficiency thanks to the significant reduction in the energy required to reach the project temperatures in the heating element in a very rapid way. The inductor does not heat the preform directly, but takes to the temperature set, through the concentration of the magnetic flow, generated by the passage of current, a conductor material of a particular form that, by irradiation and convection, in turn heats the PET.

  • Publication number: 20100292308
    Abstract: In Caenorhabditis elegans, lin-4 and let-7 enclode 22- and 21-nucleotide RNAs, respectively, that function as key regulators of developmental timing. Because the appearance of these short RNAs is regulated during development, they are also referred to as “small temporal RNAs” (stRNAs). We show that many more 21- and 22-nt expressed RNAs, termed microRNAs, (miRNAs), exist in invertebrates and vertebrates, and that some of these novel RNAs, similar to let-7 stRAN, are also highly conserved. This suggests that sequence-specific post-transcriptional regulatory mechanisms mediated by small RNAs are more general than previously appreciated.
