  1. 1. Organic Materials-based Electrochemical Flow Cells for Energy Applications

    Författare :Penghui Ding; Reverant Crispin; Viktor Gueskine; Mikhail Vagin; Brian Seger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To meet the 2015 Paris Agreement requirement of limiting global warming to 1.5 °C, the transition from fossil fuels to renewables (solar and wind) necessitates a rapid change of the energy landscape. LÄS MER

  3. 2. Aspects of optimizing pulp fibre properties for tissue and packaging materials

    Författare :Hafizur Rahman; Armando Cordova; Per Engstrand; Börje Norlin; Göran Bengtsson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To improve the competitive advantages of pulp fibre-based materials for tissue and packaging over fossil-based products, it is essential to increase knowledge of the selectivity of the cooking and the chemimechanical processes by optimizing the unit operations of impregnation, cooking and refining. A general goal in pulping processes is to achieve as efficient and even fibre separation as possible. LÄS MER

  4. 3. Design Principles for Network Distributed Denial of Service Defense

    Författare :Todd Booth; Karl Andersson; Tero Päivärinta; Antonios Michalas; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DRDoS; DDoS; Network Security; DSR; Information systems; Informationssystem;

    Sammanfattning : People, organizations and society are become more and more dependent upon access to Information Systems. Most Information Systems are accessible via the Internet. It is becoming easier and easier to perform successful network attacks against these Information Systems, which causes the system to become unavailable for its intended users. LÄS MER

  5. 4. Restraint in structures with young concrete : Tools and estimations for practical use

    Författare :Majid Al-Gburi; Carsten Vogt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. LÄS MER

  7. 5. Epitaxy of oxide and nitride thin films grown by magnetron sputtering

    Författare :Faezeh Alijan Farzad Lahiji; Per Eklund; Arnaud Le Febvrier; Biplab Paul; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. LÄS MER
