Electrodeposition of CoNi alloys in a biocompatible DES and its suitability for activating the formation of sulfate radicals

Building a sustainable future requires new, accessible, economic, and ecological methods of preparing nanostructured materials used in biomedical and environmental applications. In this work, a detailed study on the electrodeposition process of CoNi in a biocompatible deep eutectic solvent (DES) is...
