New paper published in ChemSusChem on lignin-derived carbon for water desalination
New paper published in ChemSusChem shows the high desalination performance that can be achieved with the use of lignin-derived activated carbon. Considering the low cost and high availability of lignin, lignin-derived activated carbons are very attractive electrode materials. Our work show the importance to carefully balance the potential and charge of a desalination cell and […]
New paper published in ChemSusChem on switchable ion selectivity
New paper published in ChemSusChem on the use of ion-specific insertion potentials to switch the ion-uptake preference of titanium disulfide. Our proof of concept work exemplifies the switchable preference of titanium disulfide to uptake either Cs or Mg. We expect our concept to be adaptable to many other ionic systems and other electrode materials

New paper published in Desalination on CDI with an aqueous/organic bi-electrolyte
New paper published in Desalination moves our concept of concentration-gradient membrane CDI to a new level: by using an organic electrolyte in one compartment of a 3-channel setup, it is possible to operate the electrode in that compartment at an electrode potential much higher than for an aqueous electrolyte. Thereby, a high desalination capacity of […]
