New paper published in ChemSusChem on the use of vanadium pentoxide decorated multiwall carbon nanotubes for energy efficient desalination of brackish water and sea water. This work was in collaboration with the Chair of Functional Materials of Saarland University.
Welcome our new EEIGM Master students Sidonie Carpier and Rose Zwingelstein! Both students will be working on electrochemical materials and will be with us for the next half-year.
New paper published in Journal of Physical Chemistry C on ion electrosorption of ionic liquids. Using the synergy of electrochemical dilatometry and electrochemical quartz crystal microbalance methodology, important information can be derived. We found that the charging mechanism at low charge is characterized by the exchange of more smaller ions by fewer larger ions. At higher charges, the system is changing to preferred counterion adsorption, which is resulting in a strong increase in the electrode volume. This work was in collaboration with Bernhard Roling from Philipps-Universität Marburg.
Volker Presser is giving the “Materials in Society’ Lecture” at the International Conference on Diamond and Carbon Materials (DCM) in Gothenburg, Sweden. The title of the oral presentation on September, 6th, is: “Carbon and carbon hybrid materials for electrochemical desalination”.
There are two contributions with our work at this year’s Annual Meeting of the International Society of Electrochemistry. On August 29th, Juhan Lee is giving an invited oral presentation wiht the title “Redox-enabling nanoporous carbons for high-performance energy storage” and collaborator Bastian Etzold (TU Darmstadt) is giving an oral talk on “Core-shell carbide-derived carbons as platform for high performance electrochemical energy storage and electrocatalysis”.
Benjamin Krüner is presenting work at the 254th ACS National Meeting & Exposition in Washington DC, USA. His oral presentation has the title “Sub-micrometer novolac-derived carbon beads as electrodes for supercapacitors, redox electrolyte hybrids, and Li-S batteries.”.
Collaborator Christian Kozwara presents joint work at the Joint Annual Meeting of Swiss and Austrian Physical Society (SPS/ÖPG) meeting in Geneva, Switzerland. His presentation is entitled “Electrode swelling during ion electrosorption in carbon based supercapacitors”.
New paper published in ACS Applied Materials & Interfaces on in situ electrochemistry. Using electrochemical quartz crystal microbalance methodology, we can discern different mechanical responses of binder materials, such as polyvinyldifluoride or sodium carboxymethyl cellulose. This work was in collaboration with the Aurbach Group at Bar Ilan University, Israel.
Simon Fleischmann is presenting work at the International Nanoscience Student Conference (INASCON) in Bristol, UK. His oral presentation is entitled “Hybridization of carbon/metal oxides for electrochemical energy storage”.
Christian Prehal from the Institute of Physics at Montanuniversität Leoben (Austria) is presenting joint work on in situ tracking of ion electrosorption in nanoporous carbon at the XXVI International Materials Research Congress (IMRC) in Cancun, Mexico. The invited lecture is entitled “Structure and kinetics of ions in nanoporous carbon supercapacitors studied by in situ X-ray scattering and atomistic modelling”.
