However, the state-of-the-art electrolytes for lithium-ion batteries are based on organic solvents and Li-salts (typically 1M concentration) and are known to be volatile and to degrade at higher temperature. In the search for a safer electrolyte, highly concentrated electrolytes (HCEs) and ionic liquids (ILs) have been proposed as alternatives. The high salt concentration in HCEs (typically &gt;4M) results in an increased electrochemical stability whereas ionic liquids, consisting only of ions, are known to have a negligible vapour pressure and high thermal stability. A common feature for HCEs and ILs is an ordering on mesoscopic length scales, normally not found in simple liquids, resulting from correlations between the ions. This nanostructure can be expected to influence the ion transport and a key to develop these new electrolyte concepts is to understand the structure and dynamics on the molecular level and how this links to macroscopic transport properties.</span></div> <div> </div> <div><br /></div> <div> </div> <div>The thesis focuses on the understanding of mesoscopic structure and dynamics in ILs and HCEs with the help of neutron and X-ray scattering with the aim to identify how local dynamical processes are influenced by the nanostructure. I have investigated an archetypal HCE system where the Li-salt LiTFSI is dissolved in acetonitrile and a model ionic liquid. Varying the Li-salt concentration in the HCE we can link the local processes to the development of the structure. The ion transport in the HCE takes place by the means of a jump diffusion and is highly dependent on the salt concentration and temperature of the system. For the ionic liquid we investigate the response of structure and dynamics to changes in both pressure and temperature with a particular focus on state points (P,T) where the macroscopic dynamics i.e. conductivity is constant. A confined diffusion was found with a diffusion coefficient in agreement with macroscopic conductivity, thus providing a link between the microscopic and macroscopic dynamics.​</div> <div> </div> - Ceremony and lecture – Gothenburg Lise Meitner Award 2020<p></p><p>​Due to the Coronavirus situation, the ceremony will be postponed. The organizers will be back with a new date during autumn 2020. Professor Anne L’Huillier, Lund University, Sweden is the winner of the Gothenburg Lise Meitner Award 2020. She will visit the Gothenburg Physics Centre to receive the award and give the traditional award lecture in honour of the Austrian-Swedish physicist Lise Meitner. ​ Professor L’Huillier receives the award “For pioneering contributions to attosecond laser science and technology”. ​</p><img src="/SiteCollectionImages/Centrum/Fysikcentrum/Gothenburg%20Lise%20Meitner%20Award/Lise%20Meitner%202020/150_Anne_H_.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:110px;height:146px" />Professor Anne L'Huillier has been at the forefront of ultrafast laser science since its inception, with her pioneering contributions to high-order harmonic light generation, which is a base technology for attosecond science. Her research has helped foster the field of attosecond science, allowing scientists to visualize the movements of electrons in light-induced processes, which can be used to understand chemical reactions on the atomic level.​<br /><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about<strong> </strong><span style="font-weight:300"><strong>Professor L'Huillier's</strong> </span>research​</a><br /><a href="/en/centres/gpc/activities/lisemeitner/Pages/default.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about The Gothenburg Lise Meitner Award and previous laureates​​</a> webinar: Quantum Transport in High Mobility 2D Materials<p>Online</p><p>​Jeanie Lau, Ohio State University, USA Join on Zoom:​ Password: 2d-tech510</p>​Abstract:<div>TBA </div> webinar: Chemical properties and catalytic applications of exfoliated Black Phosphorus<p>Online</p><p>​Maurizio Peruzzini, National Research Council, Italy  Join on Zoom:​ Password: 2d-tech191</p>​​Abstract:<div>TBA</div> Albinsson, Physics<p>FB, lecture hall, Fysikgården 4, Fysik Origo</p><p>​Title of thesis: &quot;Operando single particle catalysis:Combining a nanoreactor and plasmonic nanospectroscopy</p><b>​A​bstract:</b> To be announced webinar: Electromagnetic and Quantum Transport in the Multiphysics Modeling of Nanodevices<p>Online</p><p>​Luca Pierantoni, Università Politecnica delle Marche, Italy Join on Zoom:​ Password: 2d-tech211</p>​Abstract:<div>TBA [WP Energy]</div> <div><br /></div> webinar: Optical signatures of strongly correlated electrons in two dimensional semiconductors<p>Online</p><p>​Atac Imamoglu, ETH Zurich, Switzerland Join on Zoom: Password: 2d-tech111</p>​​Abstract:<div>TBA</div> <div><br /></div> webinar: Design and potential applications of nanomaterial in food packaging<p>Online</p><p>​Guidetti Gloria, Tetrapak Packaging, Modena, Italy  Join on Zoom:​​46 Password: 2d-tech311</p>​Abstract: <div>TBA</div> <div><br /></div> webinar: Combining 2D and 1D nanomaterials towards smart electronics for wireless applications<p>Online</p><p>​George Deligeorgis, Foundation for Research &amp; Technology Hellas, Crete, Greece​ Join on Zoom: Password: 2d-tech141</p>​​Abstract:<div>TBA <span style="background-color:initial">[WP Energy]​</span></div> <div><span style="background-color:initial"><br /></span></div>
