1. 1. Interplay of the Electrical and Mechanical Properties of Conjugated Polymers

   Författare :Sepideh Zokaei; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; organic electronics; organic semiconductors; doping; copolymers; conjugated polymers; mechanical properties; composites; blends; electrical properties; conducting fibers;

   Sammanfattning : Knowledge about organic semiconductors has drastically developed in the past decades. They have a myriad of applications in areas such as energy harvesting and storage, bioelectronics and wearable electronics. For most of these applications, mechanical flexibility is desirable.

3. 2. Mechanical Pulp Based Nano-ligno-cellulose : Production, Characterisation and their Effect on Paper Properties

   Författare :Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Kristin Syverud; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose NLC ; handsheets; strength properties; crill;

   Sammanfattning : Almost all research on biorefinery concepts are based on chemical pulping processes and ways of utilising lignin, hemicelluloses and extractives as well as a part of the remaining cellulose for production of nano materials in order to create more valuable products than today. Within the Forest as a Resource (FORE) research program at FSCN we are utilising the whole chain of unit processes from forestry to final products as paper and board, where the pulping process research focus on high yield process as TMP and CTMP.

4. 3. Material Properties of Cereal Protein Films

   Författare :Thomas Gillgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasticization; avenin; prolamin; kafirin; mechanical properties; water vapour permeability; oxygen permeability; protein; film; glass transition temperature; zein;

   Sammanfattning : Materials that are renewable and biodegradable are demanded due to environmental aspects. Biopolymeric materials, such as materials from prolamins, fulfil both of these requirements. Prolamins are cereal storage proteins. Examples of such are zein, gluten, kafirin and avenin from maize, wheat, sorghum and oats, respectively. LÄS MER

5. 4. A toolbox for improving the processability of composites with a high content of thermomechanical pulp

   Författare :Seyedehsan Hosseini; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface.; thermomechanical pulp; magnesium stearate; mechanical properties; composite; molybdenum disulfide; AKD;

   Sammanfattning : The use of oil-based products causes large volumes of non-biodegradable waste and contributes to climate changes. Focus has consequently shifted towards the use of polymers derived from wood. The processability of such polymers, however, presents a challenge but this can be overcome through the use of composite materials, i.e. LÄS MER

7. 5. Material Properties of Starch and Cereal Protein Films and Foams

   Författare :Thomas Gillgren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; foam; avenin; oxygen permeability; amylopectin; water vapour permeability; plasticization; mechanical properties; zein; film; glass transition temperature; kafirin; prolamin; cereal protein; amylose; starch;

   Sammanfattning : Materials that are renewable and biodegradable are demanded for environmental reasons. Biopolymeric materials, such as materials from starch and cereal proteins, are both renewable and biodegradable. However, starch and cereal protein materials are generally rather brittle and therefore need to be plasticized to become more flexible. LÄS MER
