Mohammad Torkamanzadeh is giving an oral presentation entitled “Electrochemical seawater desalination with Ti3C2Tz MXene” at the 31st International Conference on Diamond and Carbon Materials (online due to COVID-19). Tune in on September 6th at 4:40 PM.
Two contributions from our team at the GDCh Science Forum Chemistry 2021:
Mohammad Torkamanzadeh is giving an oral presentation entitled “MXene for electrochemical water treatment” on August 31st at 2:50 PM.
Lei Wang is presenting a poster entitled “Evolution of electrochemical desalination technologies”.
Volker Presser is giving an invited oral presentation entitled “Electrochemical water desalination with MXene” at the 2021 ACS Fall Meeting in Atlanta, USA. Due to the pandemic situation, the contribution was made via video from Saarbrücken. His contribution was part of the special symposium honoring Yury Gogotsi for receiving the American Chemical Society (ACS) Chemistry of Materials Award.
New paper published in Current Opinion in Electrochemistry on three generations of electrochemical desalination. Starting with capacitive deionization with carbon in the 1960s to desalination batteries in the 2010 to now including electrocatalytical processes, the field of electrochemical desalination has become truly diverse.
New paper published in Sustainable Energy & Fuels on the degradation processes of lithium iron phosphate during electrochemical lithium recovery. Removal of dissolved oxygen suppresses the degradation but also coating of LFP with a thin layer of carbon. This work was done in collaboration with the group of Guido Kickelbick at Saarland University.
Welcome to our team, Panyu Ren! Ms. Ren is a graduate from the Chinese Northwestern Polytechnical University and will be working on flow electrodes.
New paper published in ACS Nano on the significantly reduced wear on a metal surface after electro-spray coating with MXene. The work was spearheaded by colleages from Austria (TU Vienna) and Saarland University (MECS), and capitalized on the synergy of collaboration between Austria, Chile, China, Germany, and the United States of America. Our work also was featured in the news, for example:

New paper published in Cell Reports Physical Science on the use of a conventional fuel cell concept, enhanced by an additional flow channel, for the facile and continuous desalination of seawater. The device consumes oxygen and hydrogen gas and produced electricity, desalted water, and an acid/base couple which conveniently can be used to generate heat.
Volker Presser presents on May 12th at the CDI&E 2021 conference work on desalination fuel cells with the title “Charge-transfer enabling of electrochemical interfaces: the third generation of capacitive deionization”.
Our collaborative MXene tribology work to-be-published in ACS Nano tracks media attention:

New paper published in Macromolecular Rapid Communications. Our collaborative with with colleagues from Saarland University (teams of Markus Gallei and Andre Schäfer) and TU Darmstadt shows the synthesis of polyferocenylmethylene and its properties (showcasing reversible electrochemistry).
Volker Presser is supporting the junior research academy of the German Research Foundation (DFG) “Keramische Werkstoffe: Von den Grundlagen zur Anwendung” with a talk on how to “Boldly go into the unknown”.
New paper published in Chemical Communications on the synthesis and electrochemical application of titania-loaded carbon spherogels. This work continues our collaboration on spherogels with many scientists, foremost with Michael Elsaesser (see his website www.carbon-spherogels.com)
We have several contributions to the 29th ISE Topical Meeting Energy and water: electrochemistry in securing the sustainable society development. On April 19th, Yuan Zhang is giving an oral presentation on “Sub-nanometer carbon confinement: pore size effect on ion permselectivity and selectivity”. On April 21st, Volker Presser is giving an oral presentation on “Beyond the double-layer: charge-transfer processes for high-performance desalination batteries”. Also, Stefanie Arnold is giving an oral poster presentation on “Antimony alloying electrode for high-performance sodium removal: how to use a battery material not stable in aqueous media for saline water remediation”.
Welcome new Postdoc Dr. Qingsong Wang! Having obtained his Ph.D. at the University of Chinese Academy of Sciences and worked at Karlsruhe Institute of Technology (KIT) Institute of Nanotechnology, he will be working on MXene and other next-generation electrode materials.
Welcome visiting Ph.D. student Antonio Gentile! Antonio is from University of Milano-Bicocca (group of Riccardo Ruffo) and will be working in the coming six months on MXene electrode systems.
New paper published in Chemical Engineering Journal on the correlation of ion size / hydrated ion / pore size of sub-1-nm carbon pores. The work was done in collaboration with the team of Guang Feng (HUST, China). The work demonstrates how ion selectivity in mixed ionic systems cannot reliably be predicted by single-salt baseline testing. Also, we demonstrate the importance of durability testing since effects such as ion sieving may very well vary and change over time.
Welcome new Ph.D. student Yunjie Li! Having done her Master at Shandong University, Yunjie will be doing her Ph.D. study with us on lithium-ion batteries.
Welcome new Master Student Wyatt Bellville! Wyatt is enroled at the AMASE program and will carry out his 6 month Master thesis in our team on the topic of MXene derived electrode materials.
Broadcasted online and free to join, Volker Presser is presenting work on electrochemical desalination at the Chemistry Colloquium of Missouri S&T; see online for more details:
