1. 11. Experimental Characterization of Electrodes and Multi-Scale Modeling of Swelling Induced Stresses in Lithium-ion Batteries

   Författare :Priyank Gupta; Peter Gudmundson; Göran Lindbergh; Erik Olsson; Elham Sahraei; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium-ion batteries; mechanical characterization; multiscale modeling; homogenization; Solid Mechanics; Hållfasthetslära;

   Sammanfattning : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. LÄS MER

3. 12. Surface and Bulk Reactivity of Iron Oxyhydroxides : A Molecular Perspective

   Författare :Xiaowei Song; Jean-François Boily; Glenn Waychunas; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Iron oxyhydroxide; adsorption; water; carbon dioxide; FTIR; molecular resolution;

   Sammanfattning : Iron oxyhydroxide (FeOOH) mineral plays an important role in a variety of atmospheric, terrestrial and technological settings. Molecular resolution of reactions involving these minerals is thereby required to develop a fundamental understanding of their contributions in processes taking place in the atmosphere, Earth’s upper crust as well as the hydrosphere.

4. 13. Thin water and ice films on minerals : a molecular level study

   Författare :Merve Yeşilbaş; Jean-François Boily; Johannes Messinger; Grégory Lefèvre; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; ice; cryosalt; minerals; rocks; atmosphere; Dynamic Vapour Sorption; FTIR; cryo-FESEM; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. LÄS MER

5. 14. Strain Gradient Plasticity Modelling of Precipitation Strengthening

   Författare :Mohammadali Asgharzadeh; Jonas Faleskog; Samuel Forest; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The introduction of particles and precipitates into a matrix material results in strengthening effects. The two main mechanisms involved in this matter are referred to as Orowan and shearing. To numerically study this phenomenon is the motivation to the research done, which is presented here in this thesis. LÄS MER
