Chandrasekaran Sakthi Vigneshwaran is a Master student working on next-generation Prussian blue based electrode materials for advanced batteries. Congratulations on being awarded a three month fellowship by the StudienStiftungSaar!
New paper published in Current Opinion in Green and Sustainable Chemistry on “Recent advances in wastewater treatment using semiconductor photocatalysts”. Can’t decide if you like water remediation or photocatalysis/semiconductors more? They both make a great match! Read about synergies and future possibilities in our latest review article in Current Opinion in Green and Sustainable Chemistry. The team of Prof. Xiao Su (Jaeyoung Hong & Ki-Hyun Cho) and I explore this interesting interfacial research – interfacial in double meaning: at the interface of fluid and solid, and at the interface of material science/electrochemistry and water research. It is exciting to explore semiconductors, for example, to target emerging contaminants, such as perfluorinated compounds.

Dr. Samantha Husmann will attend the prestigious 2022 Lindau Nobel Laureate Meeting this week. She is one of only 611 young scientists selected in a highly competitive process from across the globe. This year, the topic is chemistry, perfectly reflected by Samantha’s research on next generation electrochemical materials (including, but not limited to, Prussian blue and Prussian blue analogues). Her positive energy and visionary research perspective will enrich the LINO22!

Immensely proud of my former Ph.D. student and now Dr. Yuan Zhang for being awarded the prestigious Feodor Lynen Fellowship from the Alexander von Humboldt Foundation! She will join the team of Yury Gogotsi and her work will relate to MXene. Looking forward to strengthening also trilateral opportunities between the US, China, and Germany!

5.3 Million seconds. 87,660 hours. 10 years. But who is counting😅
Time flies by fast when you are busy. Today marks the 10-year anniversary of the Energy Materials Group, my work family, and home away from home. Starting after returning from Yury Gogotsi‘s team (where I served as Humboldt Fellow and Research Assistant Professor) on June 1st, 2012, I had the privilege of creating my own group thanks to a 3.6 M€ starting grant from Bundesministerium für Bildung und Forschung at the INM-Leibniz Institute for New Materials. We quickly diversified in topics at the energy/water research nexus, ranging now from supercapacitors to batteries, from capacitive deionization to desalination fuel cells, from ionic charge storage to ion separation. A strong backbone of our team is the ability to go all the way from material synthesis and characterization to in situ testing and (small) device benchmarking. I am grateful to our teams many alumni and alumnae, the wonderful people in our current great team, and the amazing people I am yet to meet and work with. I am very grateful to our collaborators and partners in research and science. I will abstain from giving a complete list, but I would be amiss not to mention a few very special collaborators (in alphabetical order): Doron Aurbach, Veronica Augustyn, Guang Feng, Markus Gallei, Yury Gogotsi, Frank Mücklich, Michael Naguib, Christian Prehal, Patrice Simon, Matthew Suss.
What will we be working on over the course of the next 10 years? I always tell students: the topic you may become famous for may be on a material who you have not hear from yet 😉 So I will refrain from any specific speculation here since we all know “time makes fools out of us all”. We will continue to advance our research on sustainable materials, energy materials recycling, control over ion selectivity, and high performance beyond-lithium energy storage technologies. And to push forward with our industry collaborators to transfer our next-next-generation materials and processes into applications. I cannot wait for it!
Let me close with a few accomplishments of our team from the last 10 years:
220 Peer review publications 6 Nature publishing group publications 16,489 total citations (23,662 if you include <2012)

After 2 years Covid-hiatus, the open day of Saarland University and the INM – Leibniz Institute for New Materials returned full swing on May 21st. Our team was all amped up to tell our visitors all about energy materials, water remediation, and why there is no cooler profession than being a material scientist / chemist / engineer. We discussed what an old factory ruin (of the “Blaufabrik”) in Sulzbach has to do with sodium-ion car batteries and why there is Lithium in Saarland mine water (and how to get it out). Naturally, most people were interested in our “build your own battery” station. This year, the age span from 4 to 70 and the CR2032 coin cells were equipped with Kynol activated carbon, 1 M aqueous potassium iodide solution, glass fiber separator, and a lot of positive energy. We charged them up to 1.2 V and powered a small fan to show to people: making batteries may be magical but is no mystery. I am very grateful to my wonderful team, especially Dr. Samantha Husmann, Dr. Emmanuel Pameté, Dr. Sarah Saleem, Stefanie Arnold, Behnoosh Bornamehr, Amir Haghipour, Mohammad Torkamanzadeh, and of course Christine Hartmann and Petra Lück for their support to make this day a resounding and wonderful success. And yes, our science Lego models were a big hit with many visitors (independent of their age). I am already excited about next year’s open day! Ready, set… go!

Yuan Zhang has successfully defended her Ph.D. thesis titled “Permselective and ion-selective carbon nanopores and next-generation technologies for electrochemical water treatment”. Congratulations!
New paper published in Advanced Sustainable Systems on the ion selectivity of MXene electrodes during electrochemical operation. The Tortoise and the Hare is a classic Aesop fable that we heard growing up. We learned that a clever strategy could win over physical advantages in any match of unequal rivals. In the day and age of MXene, this fable returns when we explore MXenes as an electrode material for ion separation. The structure of MXenes impacts ion preference, as was shown before. For example, Amir Razmjou’s team wonderfully investigated the d-layer spacing’s effect on ion selectivity (10.1016/j.memsci.2021.119752). Our work now explores the ion exchange within the nanoconfined electrolyte space provided by MXene layers. We see that monovalent ions like potassium are initially preferred – only to be replaced over time by bivalent ions, like Magnesium. MXene behaves thereby like carbon nanopores, for which such ion exchange processes during continued charging were demonstrated before, among others, by the team of Maarten Biesheuvel (10.1016/j.jcis.2012.06.022). The combination of kinetic and intrinsic ion selectivity may enable novel applications within the energy/water research nexus. However, a higher ion selectivity will have to be enabled for industrial applications.

New paper published in the Journal of Materials Chemistry A. Our work entitled “Design of high-performance antimony/MXene hybrid electrodes for sodium-ion batteries” explores the synergy of the 2D nanomaterial MXene (conductive, nanotextured) and antimony (large sodium-ion storage capacity via alloying). This work is the latest outcome of our collaboration with the group and team of Riccardo Ruffo (Università degli Studi di Milano-Bicocca) and Stefano Marchionna (Ricerca sul Sistema Energetico). Special thanks to visiting Ph.D. student Antonio Gentile from Riccardo’s team!

New paper published in Nature Energy entitled “Continuous transition from double-layer to Faradaic charge storage in confined electrolytes”. Our paper explores the fascinating world from ion electrosorption transitioning towards Faradaic processes when electrolytes are nanoconfined. This work was a collaboration with several groups, espcially the team of Veronica Augustyn (NC State), Yury Gogotsi (Drexel), Patrice Simone (Toulouse) and more.
