In the presentation, I will go through the making of a ´´Biosensor´´. In this device, triazoles are put together to form a receptor having selective interactions with some peptides derived from bacterial disease. This receptor will then be attached to graphene that, thanks to its formidable conductive properties, will give us an easily detectable signal when the interaction occurs.​<br /></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.

There are several techniques to obtain recycled materials with various purity, even like virgin material. These techniques include hydrochemistry, pyro chemistry and super critical fluids. All these techniques are used at Chalmers University of Technology and have pros and cos, which we will discuss. on the webinar​.<br /><br /></div> <div><br /></div> <div><span></span><span style="background-color:initial"><span style="font-weight:700"><img src="" alt="Christer Forsgren" class="chalmersPosition-FloatRight" style="margin:5px;width:175px;height:175px" />Program​</span>:<br /></span><ul><li>12 PM, The webinar starts.
