black crystal(s); spinel structure; magnetic properties; formed by reaction of CuO and Fe2O3 at ~900°C or by coprecipitation and sintering at 900°C; has been used to manufacture piezomagnets and magnetic tapes; also used as a catalyst, e.g., exhaust control [KIR78] [STR93]

• Facile Detection of Blood Creatinine Using Binary Copper-Iron Oxide and rGO-Based Nanocomposite on 3D Printed Ag-Electrode under POC Settings.: This study explores the use of a binary copper-iron oxide and reduced graphene oxide (rGO) nanocomposite for detecting blood creatinine levels. The research demonstrates how this composite, when applied to a 3D printed silver electrode, provides an efficient and accurate method for point-of-care (POC) diagnostics, which is significant for sustainable energy materials and advanced cathode materials in battery technologies (Singh et al., 2021).
