  3. 2. In vitro and in vivo oxidation of diastereomers of lignin models of arylgylcerol b-aryl ether type and heterologous expression of laccase

    Författare :Christina Bohlin; Leif Jönsson; Ming Tien; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Kemi; Chemistry;

    Sammanfattning : Enzymic and non-enzymic oxidation of lignin models of the arylglycerol β-aryl ether type was investigated in experiments aimed at providing a better understanding of the initial phase of biological lignin degradation. Product profiles and diasteromer selectivity were determined to gain knowledge of the properties of the oxidants and pave the way for evaluation of the presence of the oxidants in ligninolytic fungal cultures.

  4. 3. MATERIAL EFFICIENCY MANAGEMENT IN MANUFACTURING

    Författare :Sasha Shahbazi; Magnus Wiktorsson; Marcus Bjelkemyr; Christina Jönsson; Thomas Lindhqvist; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material efficiency; industrial waste management; manufacturing; Innovation and Design; innovation och design;

    Sammanfattning : Material efficiency is a key solution to provide a reduction in the total environmental impact of global manufacturing, which contributes to avoid generating larger volumes of industrial waste, to reduce extracting and consuming ever more resources and to decrease energy demand and carbon emissions. However, the area of material efficiency in manufacturing has been under-researched and related knowledge is limited. LÄS MER

  5. 4. Life cycle assessment of electric vehicle batteries and new technologies

    Författare :Mats Zackrisson; Magnus Wiktorsson; Martin Kurdve; Christina Jönsson; Anders Nordelöf; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA; electric vehicle; sustainability; eco-design; Production Engineering; Industriell produktion;

    Sammanfattning : Electrification of vehicles has for decades been explored as a possible solution to the problem of climate change. Today, in 2021, the issue is no longer whether the electrification of vehicle fleets ought to happen but rather how it can be achieved with as little environmental impact as possible. LÄS MER
