2. 16. Multifunctional Transition-metal Diboride Coatings Synthesized by Magnetron sputtering with Synchronized Metal-ion Irradiation

   Author : Babak Bakhit; Grzegorz Greczynski; Johanna Rosén; Paul Mayrhofer; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Refractory transition-metal diborides (TMB2), classified as ultra-high temperature ceramics, are promising materials for extreme thermal and chemical environments. There is a growing demand for employing TMB2 in high-temperature electrodes, advanced nuclear fission reactors, molten metal containment, refractory crucibles, thermocouple protection tubes in steel baths and aluminum reduction cells, reinforcement fibers, solar power, aerospace, and armor applications.

4. 17. Multifunctional Nanocellulose Composite Materials

   Author : Olof Eskilson; Daniel Aili; Robert Selegård; Erik Martinsson; Aji Mathew; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanomaterials; nanocomposites; bacterial cellulose; wound care; plasmonics; catalysis;

   Abstract : Nanoparticles (NPs) are particles with more than one dimension between 1 and 100 nm. Because of their small size, they typically display different physical and chemical properties than the corresponding bulk materials. NPs have been used in many different applications, such as in electronics, optics, catalysis, and in biomedicine. READ MORE

5. 18. Lightweight multifunctional composites : An investigation into ion-inserted carbon fibres for structural energy storage, shape-morphing, energy harvesting & strain-sensing

   Author : Ross Harnden; Dan Zenkert; Paolo Ermanni; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering;

   Abstract : The transport sector accounts for around 26% of all greenhouse gas emissions in the European Union and United Kingdom. By reducing the mass of vehicles it is possible to reduce these emissions substantially.One way to reduce vehicle mass is to use multifunctional structures. READ MORE

6. 19. Functional Nanocellulose–Tannin Materials Inspired by Nature and Traditional Processes

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

   Abstract : 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.

7. 20. Modified and hybrid cellulose-based materials for water purification

   Author : Dimitrios Georgouvelas; Aji Mathew; Henrikki Liimatainen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose; lignocellulose; membranes; water treatment; heavy metal adsorption; dye adsorption; scalability; materialkemi; Materials Chemistry;

   Abstract : The need for clean water has led to the development of several different water treatment methods as well as to a large number of organic, inorganic, hybrid and/or composite materials that are used in these methods. Cellulose, being a highly abundant biopolymer with meritorious properties, such as high mechanical strength, tunable surface chemistry, high aspect ratio and surface area, to mention a few, is exploited in the current thesis for water treatment applications.
