1. 1. Off-gassing from thermally treated lignocellulosic biomass

   Författare :Eleonora Borén; Markus Broström; Sylvia H. Larsson; Peter Björklund; Lorenz Gerber; Henrik Antti; Capucine Dupont; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; steam explosion; enclosed storage; CO; CO2; O2 depletion; VOCs; Tenax-TA; SPME; process settings; storage temperature; storage time;

   Sammanfattning : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. LÄS MER

4. 3. Enantioselective Synthesis of Sec-Alcohol Derivatives and Diols via Combined Ruthenium and Enzyme Catalysis

   Författare :Linnéa Borén; Jan-Erling Bäckvall; Romas Kazlauskas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; kinetic resolution; ruthenium catalyst; Dynamic kinetic resolution; Dynamic Kinetic Asymmetric Transformation; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

   Sammanfattning : The first part of this thesis describes the synthesis of enantiopure secondary alcohol derivatives. These syntheses are carried out via the combination of an enzyme as a resolution catalyst and a ruthenium catalyst as a racemization catalyst, in what is called dynamic kinetic resolution (DKR).

5. 4. Sustainable Personal Road Transport : The Role of Electric Vehicles

   Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Trygg; Jamil Khan; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA;

   Sammanfattning : Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. LÄS MER

7. 5. Towards sustainable personal mobility with electric cars and buses

   Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Ödlund; Maria Grahn; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA; Mobility;

   Sammanfattning : The aim of this thesis was to explore if, and then how, electric cars and buses can contribute to sustainable personal mobility. Electric vehicles have increasingly been seen as a potential sustainable solution for the transport sector due to their high energy efficiency, close to zero emissions in the use phase, and the possibility to be powered by electricity from renewable resources.
