2. 1. Thermo-Mechanical Behaviour of Refrigerated Caverns in Hard Rock

   Author : Rune Glamheden; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal deformation; rock caverns; igneous rocks; thermal properties; underground storage; low temperatures; refrigeration; thermal strain;

   Abstract : For almost 4 decades, underground caverns in hard rock have been used to store liquefied petroleum gases (LPG) and refrigerated products, such as foods and chemicals. The design of such facilities has, however, been founded on relatively limited knowledge of the reaction of rock masses to cooling. READ MORE

   Abstract : Sustainable wood nanotechnologies that combine optical transmittance and mechanical performance are interesting for new functionalities utilizing transparency. Wood is a sophisticated bio-based material with a natural hierarchical, anisotropic and porous structure. READ MORE

5. 3. Microbially mediated formation of birnessite-type manganese oxides and subsequent incorporation of rare earth elements, Ytterby mine, Sweden

   Author : Susanne Sjöberg; Christophe Dupraz; Rienk Smittenberg; Volker Brüchert; Helena Filipsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; microbial diversity; manganese oxides; birnessite; rare earth elements; subterranean; Ytterby mine; geokemi; Geochemistry;

   Abstract : Microbes exert extensive control on redox element cycles. They participate directly orindirectly in the concentration and fractionation of elements by influencing the partitioningbetween soluble and insoluble species. READ MORE

6. 4. Durable Polysulfones with Densely Sulfonated Segments for Highly Proton Conducting Membranes

   Author : Shogo Takamuku; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer electrolytes; sulfonations; polycondensation; polyaromatics; ionomers; sulfonated monomers; block copolymers; segmented copolymers; sequenced copolymers; poly arylene ether sulfone s; lithiations; sulfinations; metalations; phase-separation; highly sulfonations; macromonomers; blocky structures;

   Abstract : Fuel cells are considered as a promising alternative environmentally benign power source to the existing ones depending on petroleum oil. Especially, proton-exchange membrane fuel cells (PEMFCs) have been intensively developed during the last decade because of their wide application windows including various portable, stationary and transportation applications.

7. 5. 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
