2. 1. Bio-inspired polysaccharide nanocomposites and foams

   Author : Anna Svagan; Lars Berglund; Mats Stading; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cellulose; starch; microfibrillated cellulose; biomimetic; nanocomposite; nanocomposite foam; mechanical properties; Biomaterials; Biomaterial;

   Abstract : Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. READ MORE

4. 2. Application of Metallic Nanoparticles and Vertically Aligned Carbon Nanotubes as Interconnect Materials for Electronics Packaging

   Author : Si Chen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon nanofibers; Fracture surface; Electronics packaging; Thermal fatigue; Electrical resistance; Shear strength; Interconnect materials; Nanocomposite solder;

   Abstract : In the electronics industry, packaging is responsible to protect chip from atmosphere and provide the path for signal communication as well as thermal dissipation. The realization of these functions in a packaging system depends on the performance of interconnect materials. Any failure on the interconnect materials could make entire system down. READ MORE

5. 3. Processing and properties of nanocomposites based on polylactic acid, chitin and cellulose

   Author : Natalia Herrera Vargas; Kristiina Oksman; Aji P. Mathew; Jyrki Vuorinen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocomposite; Cellulose; Chitin; Extrusion; Polylactic acid; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : The production of bio-based and biodegradable nanocomposites has gained attention during recent years for environmental reasons; however, the large-scale production of these nanocomposites still poses challenges. The objective of this work has been to prepare bio-based and biodegradable nanocomposites via liquid-assisted extrusion and to gain a deeper understanding of the process and the relationship between the process, composition, structure and properties.

6. 4. Optical interconnects and high frequency electronic packaging : SBU-materials, material characterization, LAP- & microprocessing

   Author : Steffen Uhlig; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical interconnects; overview opto coupling components; overview planar waveguide amplifiers; large area panel processing; polymer waveguides; multilayer thin film technology; ORMOCER®; sequential build up; permittivity; dielectric loss;

   Abstract : The main objective of this thesis is to discuss and demonstrate optical interconnect technologies. These can be used to enhance the data throughput capacity of future printed circuit boards and backplanes, i.e. exchange Copper conductors with light conductors. READ MORE

7. 5. Improving properties of poly(lactic acid) biopolymer for use in food packaging

   Author : Mitul Kumar Patel; Kristiina Oksman; Mohini Sain; Marc Delgado Aguire; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biopolymer; poly lactic acid ; chitin nanocrystals; barrier properties; liquid assisted extrusion; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : The petroleum-based plastics are widely used for food packaging applications because of their low cost, easy processability, and tunable properties to meet the specific needs of food packaging. However, these polymers are non-biodegradable, leading to a substantial amount of plastic waste in both land and marine ecosystems. READ MORE
