1. 31. Functional Nanocellulose–Tannin Materials Inspired by Nature and Traditional Processes

   Författare :Konstantin Kriechbaum; Lennart Bergström; Alain Dufresne; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose; Nanofibrils; Tannin; Biobased; Films; Foams; Moisture resistance; Energy efficiency; Materials Chemistry; materialkemi;

   Sammanfattning : Renewable and biodegradable alternatives to fossil-based materials are essential as concerns over depleting finite resources and the pollution of our ecosystems are growing. Abundant, highly anisotropic, and mechanically strong cellulose nanofibrils (CNF) are attractive building blocks for the fabrication of high-performance biobased materials that can compete with their conventional fossil-based counterparts.

3. 32. Catalytic pyrolysis of lignin to produce fuels and functional carbon materials

   Författare :Tong Han; Weihong Yang; Pär Jönsson; Anker Jensen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin; Catalytic Pyrolysis; Biooil; Hydrogen; Magnetic Activated Carbon; Lignin; katalystisk pyrolys; bioolja; vätgas; magnetiskt aktiverat kol.; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : Development of renewable energy carriers and green adsorbents is an essential step in creating a fossil-free and toxin-free future of the world. Lignin is the second highest component of biomass and the only renewable resource of aromatics in nature. LÄS MER

4. 33. Electronic structure studies and method development for complex materials

   Författare :Andreas Östlin; Levente Vitos; László Udvardi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electronic structure theory; density functional theory; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : Over the years electronic structure theory has proven to be a powerful method with which one can probe the behaviour of materials, making it possible to describe and predict material properties. The numerical tools needed for these methods are always in need of development, since the desire to calculate more complex materials pushes this field forward. LÄS MER

5. 34. Direct Nanoprototyping of Functional Materials via Focused Electron Beam

   Författare :Anastasia Riazanova; Lyubov M. Belova; Cornelis W. Hagen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBID; nanoprototyping; nanopatterning; nanoscale; nanostructure; purification; Au; Co; SiO2; dimethyl gold acetylacetonate; dicobalt octacarbonyl; TEOS; Dual Beam;

   Sammanfattning : During recent years the demand for nanoscale materials with tailor-made functional properties as bulk species, is continuously and progressively rising for such fields as e.g. micro- and nano-electronics, plasmonics, spintronics, bio-technology, bio-sensing and life sciences.

7. 35. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

   Författare :Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; Uppsala universitet; []
   Nyckelord :Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

   Sammanfattning : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.
