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 more than 60 mg/g NaCl can be achieved at a stable cell voltage of 2.4 V.

Two contributions at the 2018 MRS Spring Meeting in Phoenix
This year, we have to oral presentations at the Annual Spring Meeting of the Materials Research Society (MRS) in Phoenix, USA. Simon Fleischmann gives a talk entitled “Tailored Mesoporous Carbon/Vanadium Pentoxide Hybrid Materials for Pseudocapacitive Lithium and Sodium Intercalation” on April 3rd. This work was in collaboration with Lars Borchardt (TU Dresden). Aura Tolosa gives a talk entitled “Hybrid titanium-niobium oxide/carbon electrospun nanofibers as lithium-ion battery electrodes” on April 6th.
New paper published in Fluid Phase Equilibria on molecular dynamic sumulation of the gold / ionic liquid interfase
New paper published in Fluid Phase Equilibria on the systematic comparison of force field models for the molecular dynamic simulation of the interface of gold and ionic liquids. This work was in collaboration with Guang Feng (Huazhong University of Science and Technology).
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).
