Derek Sinclair

Derek Sinclair is a Professor in Materials Chemistry at the University of Sheffield's School of Chemical, Materials and Biological Engineering. He obtained his BSc (1st Class Honours) and PhD from the University of Aberdeen, followed by post-doctoral research at Aberdeen and the University of Cambridge. His career includes academic appointments at the University of Aberdeen (1994–1999) and University of Leeds (1993–1994) before joining Sheffield in 1999.

Sinclair's research centers on oxide-based functional ceramics, with emphases on:

• Dielectrics, solid electrolytes, and mixed conductors
• Thermoelectric and piezoelectric materials
• Microwave dielectrics and ferroelectric systems
• Impedance spectroscopy and finite element modeling of electroceramics

He collaborates extensively, notably on an EPSRC Programme Grant (4CU) for Carbon Capture and Utilisation with colleagues including Tony West and Ian Reaney.

His recent publications (2023–2025) predominantly explore perovskite materials, emphasizing:

• Defect chemistry and doping strategies in Na_0.5Bi_0.5TiO₃-based systems
• Advanced impedance spectroscopy techniques for characterizing electrical heterogeneity
• Eco-friendly material processing (e.g., aqueous cold-sintering)
• Structure-property relationships in lead-free dielectrics and ferroelectrics

Sinclair has received no explicitly listed scientific awards in the provided text. His work includes significant contributions to grants, such as EPSRC projects, and he advises doctoral researchers (though no specific student names are listed). His group utilizes advanced facilities for ceramic synthesis and electrical characterization, including collaborations with national laboratories for synchrotron studies.
