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 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 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 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).
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.
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.
Our collaborative MXene tribology work to-be-published in ACS Nano tracks media attention:
