  1. 21. Quantum transport in photoswitching molecules : An investigation based on ab initio calculations and Non Equilibrium Green Function theory

    Author : Anders Odell; Anna Delin; Anders Niklasson; Jonas Fransson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; electron transport; electron structure; density functional theory; non equilibrium green function theory; Electronic structure; Elektronstruktur;

    Abstract : Molecular electronics is envisioned as a possible next step in device miniaturization. It is usually taken to mean the design and manufacturing of electronic devices and applications where organic molecules work as the fundamental functioning unit. READ MORE

  2. 22. Building Blocks for the Assembly of Nanostructures

    Author : Tina Gschneidtner; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecules; Self-Assembly; sensing; nanoparticles; plasmon;

    Abstract : The natural world and many man made technologies are driven by self-assembly, involving the autonomous organization of individual components as a result of specific local interactions into functional structures. Self-assembly is a platform from which to construct materials with a high complexity, in high precision, with an inbuilt error- correction system due to its dynamic nature. READ MORE

  3. 23. Silicon nanogaps: An electronic bridge to the molecular world

    Author : Jonas Berg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocrystals; TSRAM; Silicon nanogaps; Molecular electronics; Selective etching; Resonant Tunneling Diodes; Molecules;

    Abstract : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. READ MORE

  4. 24. Molecular-dynamics simulations of polymeric surfaces for biomolecular applications

    Author : Stela Andrea Muntean; M.A.J. Michels; M.W.J. Prins; A.V. Lyulin; Technische Universiteit Eindhoven; []

    Abstract : In-vitro diagnostics plays a very important role in the present healthcare system. It consists of a large variety of medical devices designed to diagnose a medical condition by measuring a target molecule in a sample, such as blood or urine. READ MORE

  5. 25. Studies of Molecular and Cluster Fragmentation Using Synchrotron Radiation: Measurements and Models

    Author : Andreas Lindgren; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atom- och molekylärfysik; Atomic and molecular physics; photoionization; synchrotron radiation; localized excitation; electron-ion coincidence; induced alignment; clusters; molecules; core excitation; mass spectroscopy; fragmentation; dissociation;

    Abstract : A new spectrometer for studying photoinduced fragmentation has been designed and commissioned. The instrument produces a detailed view of the energy and angular emission of fragments, which in the case of small molecules can be related to their geometry at the moment of dissociation. READ MORE
