Volcanic eruptions have impacted climate and delineated the paths of human history. Today, nearly a billion people live under direct threat of volcanic activity. The engine of volcanic eruptions is the release of volatile chemical species degassed from magma at shallow depths. To better understand Earth innerworkings and protect people from the adverse consequences of volcanic eruptions, we need to improve the methods for measurement of volcanic gases and the theories for their interpretation.</div> <div><br /></div> <div>Over the last two decades we have advanced methods for detecting and quantifiying volcanic gases using optical remote sensing methods from ground, air and space. Our efforts have been focussed on developing techniques and facilitating their use by volcano observatories around the world. This work has transformed the role of volcanic gas monitoring in predicting and following up volcanic eruptions. By increasing the level of detection we can observe gas emissions of dormant volcanoes before they wake up, by measuring continuously we can study the evolution of volcanic activity and the chemical reactions in the airborne plumes, by improving retrieval algorithms we can detect new species and obtain reliable estimates of emission under different observation conditions. Connecting this information with other geophysical signals, we can constrain the conditions inside volcanoes and improve forecasting of their activity. This information can make a difference when evacuating people at risk.</div> <div><br /></div> <div>In this lecture I will show some cases of succesful application of remote sensing to geoscience and some ideas for effective scientific collaboration. I will also present some of the remaining scientific problems which solution I hope to help finding in the near future.</div></div></div> Grieco, Space, Earth and Environment<p>SB-H4, lecture hall, Samhällsbyggnad I-II, Campus Johanneberg</p><p>​​​Impact of mesospheric dynamics and chemistry on key chemical species: 20 years of Odin/SMR satellite observations​</p>​<span style="background-color:initial">​Francesco Grieco</span><span style="background-color:initial"> will defend </span><span style="background-color:initial">his</span><span style="background-color:initial"> thesis: &quot;​Impact of mesospheric dynamics and chemistry on key chemical species: 20 years of Odin/SMR satellite observations</span><span style="background-color:initial">&quot;. </span><div>Francesco Grieco is a PhD Student at the division of Geoscience and Remote Sensing <span style="background-color:initial">at the Department of Space, Earth and Environment.</span></div> <div><br /></div> <div>Supervisor: Kristell Pérot</div> <div>Examiner: Patrick Eriksson</div> <div>Faculty examiner: Patrick Espy, professor, Department of physics, Norwegian University of Science and Technology (NTNU)</div> <div><br /></div> <div><a href="">Read the thesis and find zoom link for online defense here</a>. </div>​Solar Cell Recycling<p>online</p><p>​Welcome to listen to Burçak Ebin, when he talks about &quot;​Recycling of Critical Raw Materials for Solar Cell Industry from Production Waste and End-of-Life Solar Modules​&quot;.</p><div><br /></div> <div><b>DATE:</b> 8 DEC, 2022</div> <div><b>TIME: </b>11:00-12:00</div> <div>30 min talk, then 30 min for Q&amp;A</div> <div><b><a href="" target="_blank">ONLINE. Please register for Zoom link and password.​</a></b> You can register until the event starts.</div> <div><br /></div> <div><b>ABSTRACT</b></div> <div>Solar energy is accepted as the key to a clean energy future and limiting the effects of climate change. The energy transformation from fossil fuels to renewable sources has significant challenges due to raw material shortages. International Energy Agency has an ambitious target to reach photovoltaic (PV) solar panel capacity that covers more than 20% of the global energy demand. Although policymakers and manufacturers draw a bright future, natural source limitation is a nightmare for PV technology. Additionally, end-of-life solar panels will dramatically affect the waste stream, and currently, there is no sustainable recycling for their waste. </div> <div>Our research maps the critical metals for PV industry and their circularity and developing recycling processes of these metals from manufacturing and end-of-life waste. The analysis clearly showed that silver, indium, and gallium supplies are the bottlenecks of the industry due to resource limitations and the importance of the other industrial applications of these metals. Although recycling critical metals from production waste requires straightforward processes, there are still technical and economical challenges to implementation. Considering end-of-life PV modules, their recycling requires a com​bination of mechanical, pyrometallurgical and hydrometallurgical processing approaches. </div> <div><br /></div> <div><br /></div> <div><a href="/en/staff/Pages/Burcak-Ebin.aspx">Dr. Burcak Ebin​</a>, <span style="background-color:initial">Associate Professor, Department of Chemistry and Chemical Engineering, Industrial Materials Recycling, </span><span style="background-color:initial">is working on recycling of alkaline, NiMH and Li-ion battery waste by pyrometallurgical processes.

However, large-scale expansion of wind and solar power creates a new set of challenges. The energy supplied from these technologies is variable in both the short-term (hours and days) and the long term (weeks and seasons). High levels of Variable Renewable Energy (VRE) complicate systems operation, with a potential over-supply of electricity on windy and sunny days, which would result in periods of low electricity prices and possibly curtailment. On the other hand, when VRE production is too low to meet the demand, other power plants must be deployed, or variation management strategies such as storage, demand shifting etc. used to balance the system. </span></div> <div> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Integrated assessment models (IAMs) are often used to generate possible pathways of reaching various climate targets. Most of the scenarios provided by these models include significant amount of net negative emissions in the second half of the century. These negative emissions are provided in two main ways: via afforestation that stores carbon from the atmosphere in the biosphere; or BioEnergy with Carbon Capture and Storage (BECCS) that uses biomass to remove carbon from the atmosphere and store it in geological formations. Direct Air capture with Carbon Capture and Storage (DACCS) is increasingly being considered in the IAMs and would enable uncoupling of emissions source and capture location. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The topics of negative emissions and variability management have been treated separately and belonged to different research communities in the modelling world. The need for negative emissions is often analysed using IAMs that allow long time horizons but lack temporal detail in inter-year representation. Variability management questions on the other hand are mostly addressed using models with high temporal resolution (1 hour to 3 hours) but often covering just one year or limited geographical scope thus giving limited understanding on global emissions trajectories.  Yet for solving the climate problem, high shares of VRE and negative emissions most likely need to coexist in the same system. Furthermore, BECCS and DACCS implementation presents a complex case as they need to be integrated in the energy system and have effects on its operation and optimal composition.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">In this lecture I explore the need for net negative emissions and consequences of employing BECCS and DACCS in the electricity system with high share of VRE. Moreover, I will discuss the system benefits of negative emissions vs. using captured CO2 in electrofuels for transport - carbon-based fuels from hydrogen and captured CO2 from biomass produced with electricity as the main energy carrier.</p></div> <div>​<br /></div> Particle acceleration and radiation generation by intense lasers<p>PJ, seminar room, Fysik Origo, Campus Johanneberg</p><p>Welcome to a workshop with the title​ &quot;Particle acceleration and radiation generation by intense lasers&quot;, in PJ Seminar room, December 15.</p><p style="font-size:16px">Program</p> <p style="font-size:16px"><span style="font-size:14px;background-color:initial">Chair: </span><strong style="font-size:14px;background-color:initial">Tünde Fülöp</strong></p> <p>09:00–09:30 <strong>Andrea Macchi</strong> (University of Pisa): &quot;Surface plasmon acceleration without a grating&quot;<br /> <br /> 09:35–10:05 <strong>Charlotte Palmer</strong> (Queen's University, Belfast): &quot;Automation and optimisation of laser-driven high-repetition rate proton sources&quot;<br /> <br /> <em>10:05–10:40 Coffee break</em><br /> <br /> 10:40–11:10 <strong>Vojtech Horný</strong> (<span style="background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-attachment:initial;background-origin:initial;background-clip:initial">LULI—CNRS; École Polytechnique, CEA)</span>: &quot;Unfeasibility of the laboratory r-process studies with laser-driven neutron source&quot;<br /> <br /> 11:15–11:45 <strong>Arkady Gonoskov</strong> (Gothenburg University): &quot;Prospects for studying extreme regimes of radiation reaction using electron-light colliders&quot;<br /> <br /> <em>11:45–13:15 Lunch break</em><br /> <br /> 13:15–13:45 <strong>Caterina Riconda</strong> (Sorbonne University/Chalmers): &quot;Laser-driven pair production : from soft shower to avalanche&quot;<br /> <br /> 13:50–14:20 <strong>Tom Blackburn</strong> (Gothenburg University): &quot;QED plasma physics: what's next?&quot;<br /> <br /></p> <p>14:25<span style="background-color:initial">–</span><span style="background-color:initial">14:55</span><strong style="background-color:initial"> Dominika Maslarova</strong><span style="background-color:initial"> (Institute of Plasma Physics of the Czech Academy of Sciences): &quot;Deflection of positrons from the Breit-Wheeler pair creation by a multi-PW laser pulse&quot;</span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial">15:00</span><span style="background-color:initial">–</span><span style="background-color:initial">15:30 </span><strong style="background-color:initial">Hélène Coudert-Alteirac</strong><span style="background-color:initial"> (Gothenburg University): &quot;Attohallen: Gothenburg's attosecond science facility&quot;</span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial"></span><span style="background-color:initial">15:30 Visit to Attohallen</span></p> <div><br /></div> <p><br /></p> <p></p> <p><em>The workshop is part of the Knut and Alice Wallenberg Foundation's funded project: </em><a href=""><em>IXREP - Intense XUV and Relativistic Electron Pulses</em></a><em>. </em></p> <div><br /></div>​Gavin-McCrory.aspx​Gavin McCrory​Gavin McCrory, Space, Earth, and Environment<p>HC3, lecture hall, Hörsalar HC, Campus Johanneberg</p><p>​The unseen in between: Understanding, designing and evaluating sustainability-oriented labs in real-world contexts</p>​<span style="background-color:initial">​Gavin McCrory will defend his thesis: &quot;The unseen in between: Understanding, designing and evaluating sustainability-oriented labs in real-world contexts&quot;. </span><div>​Gavin McCrory is a PhD Student at the division of Physical Resource Theory, at the Department of Space, Earth and Environment.</div> <div><br /></div> <div>Supervisor and Examinor: John Holmberg, Physical Resource Theory</div> <div><span style="background-color:initial">Faculty examiner: Arjen Wals, Professor, Wageningen University</span><span style="background-color:initial">​</span><br /></div> <div></div> <div><br /></div> <div><br /></div>
