  1. 21. Lignin- and PAN-based carbon fibres as negative electrodes for alkali-ion batteries

    Författare :Kevin Peuvot; Göran Lindbergh; Dan Zenkert; Enn Lust; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hard carbon; lithium-ion batteries; sodium-ion batteries; potassium-ion batteries; lignin-based carbon fibres; PAN-based carbon fibres; free-standing electrodes; Chemical Engineering; Kemiteknik;

    Sammanfattning : The development of sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) have accelerated since they can now reach similar gravimetric energy densities as lithium-ion batteries (LIBs) but with a lower environmental impact. Hard carbon is the most common negative electrode for SIBs and KIBs and can be made from renewable resources such as lignin. LÄS MER

  3. 22. Efficient memory management for message-passing concurrency, Part I : Single-threaded execution

    Författare :Jesper Wilhelmsson; Konstantinos Sagonas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : Manual memory management is error prone. Some of the errors it causes, in particular memory leaks and dangling pointers, are hard to find. Manual memory management becomes even harder when concurrency enters the picture. LÄS MER

  4. 23. Garbage collection for reactive real-time systems

    Författare :Martin Kero; Roger Henriksson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Predictable use of resources, such as processor time and memory, is a desirable property for virtually any computer system. In real-time computing, static predictability is of particular concern. LÄS MER

  5. 24. Particle Deposition Studies in a Laminar Wall Jet - The Hydrodynamic Influence on the Kinetics of Colloidal Deposition

    Författare :Anders Göransson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shielding function; surface blocking; total internal reflection microscopy; laminar wall jet; random sequential adsorption; colloidal deposition; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : In the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. LÄS MER

  7. 25. Surface chemical studies on feldspar/quartz system using alkylamines and mixed (cationic/anionic/non-ionic) collectors : adsorption mechanisms and flotation selectivity

    Författare :Ari Vidyadhar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The mechanism of adsorption of long chain alkyl primary amines and, co-adsorption of amines and alcohols on quartz were studied using FTIR (DRIFT and IRRAS) and XPS spectroscopy methods. The spectroscopy data were correlated with zeta-potential and Hallimond flotation results. LÄS MER
