New paper published in Advanced Materials Interfaces on mechanisms in high-performance tin oxide / MXene batteries. As the demand for power and energy storage continues to grow, we researchers are constantly exploring new ways to improve battery performance. One promising approach involves using conversion/alloying materials, such as tin oxide, to design high-performance lithium-ion batteries. While […]
New paper published in Applied Catalysis B: Environmental which explores a promising new approach to resource recovery and wastewater treatment. Nitrate is widely distributed in industrial wastewater and contaminated water bodies, and electrochemically converting it into ammonia holds great potential. At the same time, the treatment of harmful algal blooms (HABs) presents a significant challenge […]
New paper published in npj Materials Degradation (open access). In cooperation with the group of Frank Mücklich at Saarland University and partners, we have found that coating laser-patterned stainless-steel surfaces with carbon nanotubes (CNT) or carbon onions (CO) can create an effective solid lubrication system. By storing the particles inside the pattern, lubricant retention is […]
Welcome new postdoc Dr. Gracita Tomboc! With past experience at Myongji University, Korea University, and Université du Québec à Trois-Rivières, we are excited about our upcoming joint work on energy and electrochemistry.
Welcome new AMASE Students Peter Burger and Maria Holmström! AMASE is an international Master’s program and an amazing opportunity to study not just materials science but to do so in multiple European cities! Both will be working on novel materials and methods for electrochemical desalination. Welcome to the team!
New paper published on “Unraveling the Electrochemical Mechanism in Tin Oxide/MXene Nanocomposites as Highly Reversible Negative Electrodes for Lithium-Ion Batteries” in Advanced Materials Interfaces. As the demand for power and energy storage continues to grow, we researchers are constantly exploring new ways to improve battery performance. One promising approach involves using conversion/alloying materials, such as […]
Our research team has published an article in ChemSusChem on the promising use of stable and efficient SnO2 electrodes for degrading refractory organic pollutants in wastewater treatment. Our approach involved the preparation of Ti3+ self-doped urchin-like rutile TiO2 nanoclusters (TiO2-xNCs) on a Ti mesh substrate using hydrothermal and electroreduction methods, which served as an interlayer […]
Welcome new Ph.D. student Liying Xue! Liying is from Guangxi University, China, and will be working on high entropy materials
Welcome to our team, Prof. Dr. Syed Tauqir Ali Sherazi! Having been awarded the prestigious Georg Forster Fellowship of the Alexander von Humboldt Foundation, he will be working on next-generation water remediation technologies. Our visiting Fellow is Professor at COMSATS University Islamabad Abbottabad Campus in Pakistan.
New paper published in the Journal of Industrial and Engineering Chemistry. In cooperation with former group member Choonsoo Kim (now at Kongju University, Korea), we have used redox flow desalination for the valorization of tetramethylammonium hydroxide as a value-added organic compounds from wastewater which is widely being used as an etching solvent, photoresist developer, and […]
New perspective paper published in Communications Materials. The high entropy concept is ideally suited for MXenes but also capable to be a unique tool to tailor and improve electrochemical properties in other materials. Multiple principal element or high-entropy materials have recently been studied in the two-dimensional (2D) materials phase space. These promising classes of materials […]

Very happy to see both Behnoosh Bornamehr and Mohammad Torkamanzadeh winning in the essay competition on open science / open data of Saarland University! This makes for a 100% win rate for applicants from our team 😉 Open access is not without challenges and caveats and the journey toward a world of true open science […]
New paper published in the Journal of the American Ceramic Society on the synthesis of new hybrid electrode materials for Li-ion batteries (LIBs). Through controlled oxidation of layered Ti2SnC, we were able to obtain TiO2-SnO2-C/carbide hybrid materials using two different methods: partial oxidation in an open-air furnace (OAF) and rapid thermal annealing (RTA). The resulting […]
New paper published in ACS Applied Nano Materials. Rolling bearings need lubrication to operate smoothly, but when traditional methods fail, multiwall carbon nanotubes (MWCNT) can come to the rescue. To understand how MWCNTs lubricate highly loaded contacts, we combined experimentation and large-scale molecular dynamics simulations. We applied tribometry to iron plates coated with different types […]
New paper published in Journal of Energy Storage on MXene battery electrode recycling. Even the most wonderful electrode material, some sooner than later, will degrade. Even the most wonderful battery, regardless of the used chemistry, will see the end of its life. Battery recycling, using hydrometallurgical or pyrometallurgical pathways, is very energy consuming. So are […]
New paper published in ChemSusChem in collaboration with the Kickelbick-Group at Saarland University. We have developed an exciting new class of inorganic-organic hybrid materials with redox-active components that have great potential for use in lithium-ion batteries (LIBs). The materials were prepared using an aqueous precipitation reaction of ammonium heptamolybdate (AHM) with para-phenylenediamine (PPD), and a […]
