1. 1. Multifunctional Supramolecular Organic Ferroelectrics

   Författare :Indre Urbanaviciute; Martijn Kemerink; Mats Fahlman; Bengt-Harald Jonsson; Van Dijken Sebastiaan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Ferroelectric materials are known and valued for their multifunctionality arising from the possibility to perturb the remnant ferroelectric polarization by electric field, temperature and/or mechanical stimuli. While inorganic ferroelectrics dominate the current market, their organic counterparts may provide highly desired properties like eco-friendliness, easy processability and flexibility, concomitantly opening unique opportunities to combine multiple functionalities into a single compound that facilitates unprecedented device concepts and designs.

3. 2. Eco-designed functionalization of polyester fabric

   Författare :Tove Agnhage; Guido Sonnemann; Isabelle Vroman; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-design; Life cycle assessment; Madder; Anthraquinone; Bioactive; Multifunctional; Polyester; Textil och mode generell ; Textiles and Fashion General ;

   Sammanfattning : There is an increased awareness of the textile dyeing and finishing sector’s high impact on the environment due to high water consumption, polluted wastewater, and inefficient use of energy. To reduce environmental impacts, researchers propose the use of dyes from natural sources. LÄS MER

4. 3. Synthesis of Non-Natural Aromatic Amino Acids Derivatives Solvent-free reactions-Versatile building blocks-Galectin inhibitors

   Författare :Erik Tullberg; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Naturvetenskap; Natural science; Multivalent galectin inhibitors; Multifunctional molecules; Amino Acids; Solvent-free reactions;

   Sammanfattning : This thesis deals with three topics concerning the synthesis of non-natural also known as unnatural amino acid derivatives. In the first, solvent-free reaction conditions for the Heck reaction were developed that were superior to previous conditions because the reaction time could be reduced and the work-up procedure simplified.

7. 5. Environment-Sensitive Multifunctional Drug Delivery Systems

   Författare :Jian Qin; Mamoun Muhammed; Marcus Textor; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Materialkemi;

   Sammanfattning : Drug delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms and visualization agents have motivated the biomedical community as well as materials chemists for more than a decade. This dissertation is concerned with the development of nanoparticles for multifunctional DDS  to tackle several crucial challenges in these complex systems, including polymeric nanospheres which respond to temperature change, superparamagnetic iron oxide nanoparticles/polymeric composite for magnetic resonance imaging contrast agents and drug carriers, immunoresponse of nanomaterials and injectable magnetic field sensitive ferrogels.
