3. 7. Surface modification of inorganic materials with graphene oxide : From solution to high-temperature synthesis

   Författare :Simon Tidén; Ulf Jansson; Mamoun Taher; Erik Lewin; Lars Nyborg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphene oxide; Coatings; Additive Manufacturing; Laser Powder Bed Fusion; Reactive Hot Pressing; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : The use of graphene as an additive in materials is often challenging due to the agglomeration of the two-dimensional graphene sheets. An alternative additive is graphene oxide (GO), an oxidized form of graphene, which is easily dispersed in water. LÄS MER

4. 8. Self-bonding of beech veneers

   Författare :Carmen Cristescu; Mark Hughes; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : This thesis presents studies on the self-bonding of veneers, and investigations into the properties of boards obtained by hot-pressing beech veneers without adhesives. The raw material is pressed at temperatures from 200 to 250ºC, at pressures from 4 to 6 MPa and pressing times from 240 to 360 s. LÄS MER

5. 9. Structural Silicides - Processing, Microstructure and Toughening

   Författare :Danqing Yi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toughening; solid solubility; processing; microstructures; mechanical properties; composites; silicides; crystal structure; alloying effects; phase transformation;

   Sammanfattning : Molybdenum disilicide is a promising candidate material for high temperature structural uses. However, its room-temperature toughness is rather low and has to be improved. The objective of this thesis is to improve the fracture toughness of MoSi2 by alloying and composite processes. LÄS MER

7. 10. Eco-friendly Holocellulose Materials for Mechanical Performance and Optical Transmittance

   Författare :Xuan Yang; Lars Berglund; Eero Kontturi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Cellulosic materials can be sustainable replacements for fossil-based plastics; yet for some applications improvements are needed for mechanical properties, optical transmittance and eco-friendly characteristics. In this thesis, holocellulose materials are investigated for this purpose, and processing-structure-property relationships are discussed. LÄS MER
