New paper published in ACS Sustainable Chemistry & Engineering on Mo-MXene for water desalination

New paper published in ACS Sustainable Chemistry & Engineering on the use of molybdenum carbide MXene with divacancy ordering for the effective desalination of brackish water and sea water. This work also provides the first chemical online monitoring evidence of anion intercalation in MXene and extends the use of 2D intercalation materials for the desalination of brackish water to seawater concentrations. The material synthesis was developed and carried out by our research collaborators at Linköping University, Sweden (Johanna Rosen).

New paper published in ChemSusChem on electrospun Nb-Ti-fiber electrodes for battery application

New paper published in ChemSusChem. Our joint work with the Leibniz Institute for Plasma Science and Technology (INP Greifswald) demonstrates mixed Ti-Nb metal oxide electrodes for lithium ion application. Using electrospinning, the fiber mats are free of binder, free-standing, and can be directly used as electrodes. Per nanoscale engineering, the fibers also already contained sufficient amounts of conductive carbon within each fiber, so that no additional conductive phase needed to be added.

New paper published in Chemistry of Materials

New paper published in Chemistry of Materials on the use of titanium disulfide as sodium intercalation material in aqueous media. In our quest to establish ion intercalation materials for water desalination, we demonstrate titanium disulfide as a battery-like electrode material highly suited to remove sodium ions from saline solutions. Pairing with nanoporous carbon to accomplish chlorine removal, no ion exchange membrane is needed in this hybrid Faradaic desalination concept.
