Ahmad Umar works on nanomaterials and sensor technologies, with recurring interests in metal-oxide nanostructures (like ZnO, indium oxide, tungsten trioxide) for gas sensing and photocatalysis, electrochemical biosensors for detecting disease markers, and carbon-based materials for energy storage (supercapacitors) and environmental applications. Additional recent work covers environmental remediation topics such as pesticide and heavy-metal contamination, biodegradation, and sustainable materials like biodegradable packaging films and biowaste-derived carbon composites. The work is highly interdisciplinary, spanning materials chemistry, environmental science, and applied engineering.
