New paper published in Applied Catalysis B: Environmental on upcycling of algal biomass for ammonia electrosynthesis

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 on the material degradation of tribologically loaded carbon nanotubes and carbon onions

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 […]

New paper published in Communications Materials on 2D high entropy materials

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 […]

New paper published on solid lubrication of carbon nanotubes in ACS Applied Nano Materials

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 the American Ceramic Society on oxide/carbon hybrid electrodes for Lithium-ion batteries

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 Journal of Energy storage on the recycling of MXene battery electrodes

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 on high-performance Lithium-ion battery electrodes based on polyoxomolbydate and self-activation

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 […]
