New paper published in ACS Applied Materials & Interfaces on porous mixed-metal oxides for lithium-ion batteries

New paper published in ACS Applied Materials & Interfaces. This work in collaboration with the teams of Markus Gallei and Guido Kickelbick (both at Saarland University) explores shear-induced co-assembly as a step towards creating unique (ordered) materials. The latter can be conveniently converted to metal oxide / carbon hybrids via thermal annealing. For example, titanium niobium oxide / carbon obtained this way profided 335 mAh/g at 10 mA/g and a capacity retention of 84% after 1000 cycles at 250 mA/g.

New paper published in Research on cobalt hydroxide nanostructures for high performance desalination batteries

New paper published in the AAAS journal Research on the use of hollow / nanosheet / needle-like cobalt hydroxide for the use for high performance electrochemical desalination. This material architecture allows for rapid ion removal and high stability in absence of strain-build-up. This work was done in collaboration with the team of Jie Ma at Tongji University.

New paper published on dilatometry of pillared MXene in Journal of Physical Chemistry C

New paper published in Journal of Physical Chemistry C on the origin of better long-term electrochemical performance of silica-pillared MXene. This unique material provides enhanced performance as an lithium-ion battery electrode (ca. 300 mAh/g at 20 mA/g rate). Although larger volume changes are seen for the pillared MXene, this is not a detriment to the cycling stability. This work was done in collaboration with the teams of Nuria Tapia-Ruiz (Lancaster University) and Nuno Bimbo (now: University of Southampton).

New paper published on redox-responsive 2-aminoanthraquinone core-shell particles in ACS Applied Polymer Materials

New paper published in ACS Applied Polymer Materials on the use of redox-responsive 2-aminoanthraquinone core-shell particles for structural colors and carbon capture. This work was done in collaboration with the group of Markus Gallei (Saarland University), Karin Jacobs (Saarland University), and T. Alan Hatton (MIT).

Volker Presser presents work on electrochemical desalination with MXene at the ACS Conference

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.
