2. 1. Experimental Measurement of Lateral Force in a Submerged Single Heaving Buoy Wave Energy Converter

   Author : Andrej Savin; Mats Leijon; Magnus Karlberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; Tight mooring system; Offshore measurement; Strain gauge; Estimation of stress; Lateral force; Inclination angle; Snatch load; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : The search for new solutions for the generation of energy is becoming more and more important for our future. Big arguments and disagreements on e.g. the questions of gas transport or the dependence on energy supplied by other countries raise demands on the development of new forms of alternative energy resources.

4. 2. Wood fibre deformation in combined shear and compression

   Author : Federica De Magistris; Anders Eriksson; Ola Dahlblom; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arcan; compression; density; energy; finite element analysis; Iosipescu; Picea abies; shear; wood; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. READ MORE

5. 3. Computational Studies of 2D Materials : Application to Energy Storage and Electron Transport in Nanoscale Devices

   Abstract : The field of two-dimensional (2D) layered materials provides a new platform for studying diverse physical phenomena that are scientifically interesting and relevant for technological applications. Novel applications in electronics and energy storage harness the unique electronic, optical, and mechanical properties of 2D materials for design of crucial components. READ MORE

6. 4. Thermally Conductive High-Density Polyethylene Composites for Ground Heat Exchangers

   Author : Adib Kalantar Mehrjerdi; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-density polyethylene; talc; thermal conductivity; thermal diffusivity; thermal stability; melt rheology; oxidation induction time; α relaxation; strain hardening;

   Abstract : Today, the energy used for the heating and cooling of offices, shopping centres, schools, residential areas, andother buildings is as large as 50% of the total energy consumption in the world. The climate change, globalwarming, and environmental issues have forced high requirements for energy efficiency and clean energyproduction in buildings. READ MORE

7. 5. Microscopic Theory of Externally Tunable Exciton Signatures of Two-Dimensional Materials

   Author : Maja Feierabend; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localized states; density matrix formalism; magnetic field; transition metal dichalcogenides; Bloch equations; organic inorganic heterostructures; dark excitons; strain;

   Abstract : Atomically thin transition metal dichalcogenides (TMDs) are in the focus of current research due to their efficient light-matter interaction and the remarkably strong Coulomb interaction that leads to tightly bound excitons. Due to their unique band structure, TMDs show a variety of bright and optically inaccessible dark excitonic states. READ MORE
