2. 1. Charged Higgs Bosons at the ATLAS Experiment and Beyond

   Author : Elias Coniavitis; Richard Brenner; Tord Ekelöf; Johan Rathsman; Marco Battaglia; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; MSSM; Higgs physics; charged Higgs boson; LHC; ATLAS; ATLAS Semi-Conductor Tracker; SCT; tau lepton; Lorentz angle; CLIC; Elementary particle physics; Elementarpartikelfysik; High Energy Physics; Högenergifysik;

   Abstract : In the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, direct searches for the elusive Higgs boson will be conducted, as well as for physics beyond the Standard Model. The charged Higgs boson (H±) is interesting both as a part of the Higgs sector, and as a clear sign of new physics. READ MORE

4. 2. Interfaces in Dye-Sensitized Oxide / Hole-Conductor Heterojunctions for Solar Cell Applications

   Author : Erik Johansson; Håkan Rensmo; Hans Siegbahn; Anders Sandell; Villy Sundström; Uppsala universitet; []
   Keywords : Physics; Photoelectron spectroscopy; Solar cells; Heterojunction; Fysik;

   Abstract : Nanoporous dye-sensitized solar cells (DSSC) are promising devices for solar to electric energy conversion. In this thesis photoelectron spectroscopy (PES), x-ray absorption spectroscopy (XAS) and photovoltaic measurements are used for studies of the key interfaces in the DSSC. READ MORE

   Abstract : The solid oxide fuel cell (SOFC) is a potential high efficient electrochemical device for vehicles, auxiliary power units and large-scale stationary power plants combined heat and power application. The main challenges of this technology for market acceptance are associated with cost and lifetime due to the high temperature (700-1000 oC) operation and complex cell structure, i. READ MORE

6. 4. High frequency characteristics of medium voltage XLPE power cables

   Author : Gavita Mugala; Roland Eriksson; Hans Kristian Holdalen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

   Abstract : The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. READ MORE

7. 5. Group 11–14 Triazenides : Synthesis, characterization, and thermal evaluation for use in chemical vapor deposition

   Author : Rouzbeh Samii; Henrik Pedersen; Nathan O´brien; Andrew Johnson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Chemical vapor deposition (CVD) and atomic layer deposition (ALD) are corner-stone techniques for depositing thin films in semi-conductor manufacturing. To deposit semiconductor grade materials, these techniques rely on high-performance precursors. READ MORE
