Chemistry – A European Journal, EarlyView.It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study
Chemie Ingenieur Technik, EarlyView.This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.

Characterization of a two‐phase hybrid flotation column
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study explored the performance of a novel hybrid flotation column, which combines the advantages of a mechanically agitated cell with a flotation column and compared the results with a conventional flotation column setup. The experiments were performed in an air/water two‐phase system under varying airflow rates, frother concentrations ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...
