    Notes: Single-electron transistors utilizing Coulomb blockade effects are promising candidates for future silicon based nanoelectronics. We present the fabrication of such transistors and measurements that reveal Coulomb blockade behavior. Various silicon quantum dots are investigated up to room temperature. We employ a dual gate configuration with which we are able to control our devices by both a metallic top gate as well as by an in-plane gate. This design principle enhances the integration density. © 2001 American Institute of Physics.

    Single-electron tunneling in highly doped silicon nanowires in a dual-gate configuration (2001)

    Notes: Lateral patterning of highly doped silicon-on-insulator films allows us to observe conductance oscillations due to single-electron charging effects. In our devices, silicon nanostructures are embedded into a metal–oxide–silicon configuration. The single-electron effects can be tuned both by an in-plane sidegate, as well as by a metallic topgate, a technology which is compatible with large-scale integration of single-electron devices with dimensions down to 10 nm. We compare the influence of different gating electrodes, important for ultralarge scale integration, on the electron islands. © 2001 American Institute of Physics.

    Single-crystalline silicon lift-off films for metal–oxide–semiconductor devices on arbitrary substrates (2000)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: We present a technique to mount single-crystalline silicon thin films on arbitrary substrates. We demonstrate in detail the preparation of a 190-nm-thin silicon metal–oxide–semiconductor field-effect transistor (MOSFET) on a silicon-on-insulator film lifted from its substrate and bonded to quartz. Functioning of this hybrid MOSFET on a rigid surface at room temperature is demonstrated. © 2000 American Institute of Physics.

    From scarless fetal wounds to keloids: Molecular studies in wound healing (2003)

    Notes: Surgical researchers were among the first to describe the different phases of wound healing and the events in tissue repair and regeneration that were taking place during each phase. The understanding of these events has been significantly enhanced in recent years by modern techniques in molecular and cellular biology. In this article, we discuss new findings in scarless fetal repair, angiogenesis in wound healing, and keloid pathogenesis. This serves to highlight the advances that have been made and also how much remains to be understood. (WOUND REP REG 2003;11:411–418)

    Notes: Abstract. We present a brief overview on different realizations of single-electron devices fabricated in silicon-on-insulator films. Lateral structuring of highly doped silicon films allows us to observe quasi-metallic Coulomb blockade oscillations in shrunken wires where no quantum dot structure is geometrically defined. Embedding quantum dot structures into the inversion channel of a silicon-on-insulator field-effect transistor Coulomb blockade up to 300 K is observed. In contrast to the quasi-metallic structures, in these devices the influence of the quantum mechanical level spacing inside the dot becomes visible. Suspending highly doped silicon nanostructures leads to a novel kind of Coulomb blockade devices allowing both high-power application as well as the study of electron–phonon interaction.

    Role of apoptosis in autoimmunity (2000)

    Notes: Abstract Apoptosis is a physiological form of cell death required to ensure that the rate of cell division is balanced by the rate of cell death in multicellular organisms. Dysregulation of apoptosis is associated with the pathogenesis of a wide array of diseases: cancer, neurodegeneration, autoimmunity, heart disease and others. In this review we collect arguments supporting a hypothesis of a dysregulated apoptosis leading to development of autoimmunity like systemic lupus erythematosus (SLE). This notion is supported by occurence of known autoantigens in apoptotic blebs, in vitro findings of an increased rate of apoptotic lymphoblasts despite optimal cytokine stimulation combined with a defective in vitro clearance of apoptotic bodies by SLE phagocytes. Moreover, we and others could generate histone-specific lymphocytic cell lines from cells after activation with autologous apoptotic material. These lymphocytes could stimulate autologous B-lymphocytes to produce of anti-dsDNA antibodies, a diagnostic hallmark for SLE. Finally, antibodies against phospholipids like phosphatidylserine are often associated with systemic autoimmunopathies like SLE and others. Phosphatidylserine is exposed on apoptotic cells as early sign of programmed cell death and serves as phagocyte recognition molecule for apoptotic cells. Formation of immune complexes and deposition in tissues might lead to organ damage and disease. This scenario will be discussed in this review in detail.
