    Sammanfattning : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. LÄS MER

  3. 2. Architectures, design methodologies, and service composition techniques for Grid job and resource management

    Författare :Per-Olov Östberg; Erik Elmroth; Umeå universitet; []
    Nyckelord :;

    Sammanfattning : The field of Grid computing has in recent years emerged and been established as an enabling technology for a range of computational eScience applications. The use of Grid technology allows researchers and industry experts to address problems too large to efficiently study using conventional computing technology, and enables new applications and collaboration models.

  4. 3. Transmission Electron Microscopy of Graphene and Hydrated Biomaterial Nanostructures : Novel Techniques and Analysis

    Författare :Sultan Akhtar; Klaus Leifer; Hilborn Jöns; Stefano Rubino; Marco Cantoni; Uppsala universitet; []
    Nyckelord :Graphene flakes; magnetic beads DNA coils; hydrated biomaterials; transmission electron microscopy; focused ion beam scanning electron microscopy; bright-field dark-field imaging; high resolution imaging; electron diffraction and cryogenic temperatures; Materialvetenskap; Materials Science;

    Sammanfattning : Transmission Electron Microscopy (TEM) on light element materials and soft matters is problematic due to electron irradiation damage and low contrast. In this doctoral thesis techniques were developed to address some of those issues and successfully characterize these materials at high resolution. LÄS MER

  5. 4. Studies on Rechargeable Fe-air electrodes in Alkaline electrolyte

    Författare :Alagar Raj Paulraj; Yohannes Kiros; Carlos Ponce de León Albarrán; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fe-air battery; Cu Sn-doped nanostructured iron electrodes; Alkaline electrolytes; Bi-functional OER ORR catalyst; perovskite spinel catalyst; NiFeOx; air electrode; Chemical Engineering; Kemiteknik;

    Sammanfattning : Energy storage system is an important component in the energy system based on variable renewable energy sources into the grid. Energy storage system could contribute to decarbonization, energy security, offset the demand and supply of the electricity sector, especially for the electric grid. LÄS MER

  7. 5. Power Flow Analysis of the Swedish Railway Electrical System

    Författare :Magnus Olofsson; Göran Andersson; Elkraftteknik KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis deals with analysis of the steady state power flow in the Swedish railway electrical system. Finding the steady state of the system means that all voltages and power flows in the system are known. The trains are supplied from the public grid using frequency converters. LÄS MER
