New paper published on cation separation during flow electrode capacitive deionization in Desalination

New paper published on cation separation during flow electrode capacitive deionization in Desalination. This work is about improving water treatment and resource recovery through selective ion removal using flow electrode capacitive deionization (FCDI). We explore separating specific cations like calcium and magnesium from multi-ion solutions, helping to optimize water desalination processes. Our data show that […]

New paper published in Nature Communications

New paper published in Nature Communication. This highly collaborative work (spearheaded by Dr. Gündoğ Yücesan) presents polyphosphonate covalent organic frameworks (COFs) constructed via P-O-P linkages, synthesized through a one-step condensation reaction. This process involves heating a hydrogen-bonded precursor made from phenylphosphonic acid and porphyrin, without chemical reagents. At temperatures above 210 °C, the COF transforms into […]

New paper published in Batteries&Supercaps on upcycling of supercapacitor electrodes for water desalination

New paper published on “Life after death: Re-purposing end-of-life supercapacitors for electrochemical water desalination” in Batteries & Supercaps. Even the best supercapacitor, at some point, will reach its end-of-life. With limited amounts of precious elements (unlike lithium-ion batteries), elemental extraction of the active material’s components is not really attractive for supercapacitors. More interesting is to […]

New paper published on NGC-MXene in Advanced Science

New research paper from our collaboration with Michael Naguib: “Nitrogen-Doped Graphene-Like Carbon Intercalated MXene Heterostructure Electrodes for Enhanced Sodium- and Lithium-Ion Storage” published in Advanced Science. We’ve developed a novel N-doped graphene-like carbon intercalated Ti3C2Tx (NGC-Ti3C2Tx) heterostructure. But wait… why would one want to add something in-between the MX-layers, the wonderful interlayer space that should […]
