    Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER

  4. 3. Tracing Smartphone-Enabled Customer Journeys : A Socio-Material Approach

    Författare :Patrik Stoopendahl; Jens Hultman; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Customer journey; Socio-material perspectives; Trace ethnography; Agency; Smartphone; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : This doctoral thesis delves into the transformation of the customer journey—that is, the direct and indirect interactions between a customer and retailer over time—in the smartphone era. Using a socio-material perspective, it goes beyond current visions of the customer journey, which often focus on emotions and experiences, and instead explores how agency is distributed across elements that include consumers and their relationship with their smartphone as a device and a gateway to a digital market infrastructure.

  5. 4. Catalytically active and corrosion resistant cobalt-based thin films

    Författare :Clara Linder; Emma Björk; Per Eklund; Sara Munktell; Anna Martinelli; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Oxygen reduction reaction; Corrosion; Thin film.;

    Sammanfattning : Oxygen reduction reaction (ORR) has considerable potential for the pro-duction of electricity, issues with water splitting and many other applications in the energy sector. But in order to increase the efficiency of the reaction an electrocatalyst needs to be introduced. LÄS MER

  7. 5. Adaptive Active Control of Machine-Tool Vibration in a Lathe - Analysis and Experiments

    Författare :Lars Håkansson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Metal Cutting; Lathe; Tool Vibration; Active Control; Adaptive Signal Processing; materialteknik;

    Sammanfattning : In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. LÄS MER
