1. 31. Environmental Impacts of Shared Mobility: Potential, Factors, and Assessments

   Författare :Ana Maria Arbelaez Velez; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shared mobility; Environmental impact; sustainable transportation; input and output analysis; Life Cycle Assessment LCA; demand-side solutions;

   Sammanfattning : Environmental impacts from passenger transportation continue to increase globally due to a rise in kilometers traveled and a shift to emission-intensive transportation modes (from public transportation and active modes such as walking and cycling to motorcycle and car ridership). The electrification of the passenger fleet, coupled with low-carbon energy sources, is expected to decrease some of the environmental impacts associated with passenger transportation, including local air pollution, greenhouse gas emissions and fuel depletion.

3. 32. Towards a retro-structural design of degradable aliphatic polyester-based materials

   Författare :Veluska Arias; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrolysis; polyesters; polylactide; hydrophobicity; crystallinity; miscibility; nanoparticles; stereocomplex; homocomposites; Kemi; Chemistry;

   Sammanfattning : The increasing amount of accumulated plastic waste has led to a continuous search for degradable materials for use in a variety of applications. This eco-friendly approach contemplates the use of degradable alternatives to the inert polymers (the main components in plastics) used today and further engineering of their degradation pathways.

4. 33. Nanocellulose based 3D printed hydrogel scaffolds for cartilage and bone regeneration : Tuning of composition, pore structure and functions

   Författare :Sahar Sultan; Aji P. Mathew; Lennart Bergström; Gustav Nyström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose materials; 3D printing; gradient biphasic hydrogel scaffolds; metal-organic frameworks; hydroxyapatite; cartilage and bone regeneration; osteochondral scaffolds; materialkemi; Materials Chemistry;

   Sammanfattning : Biobased-materials with customized scaffolds have played a prominent role in the success of tissue engineering (TE). Cellulose nanomaterials (CNM) isolated from the abundant biopolymer, cellulose, is explored in this thesis for TE engineering due to its versatile properties such as biocompatibility, high specific strength, surface functionality and water retention capacity.

5. 34. Surface modification of cellulose-based fibres for use in advanced materials

   Författare :Simon Utsel; Lars Wågberg; Mikael Lindström; Magnus Norgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

   Sammanfattning : The awareness of our need for a sustainable society has encouraged the search for renewable, high quality materials that can replace oil-based products. This, in combination with increased competition in the forest industry, has stimulated a lot of research into different types of wood-based materials where cellulose-rich fibres are combined with different types of polymers.
