Molecular Biomarker Constraints on Organic Matter Provenance and Thermal Maturity of the Late Cretaceous Fika and Gongila Shales, Chad Basin, Northeastern Nigeria

G. O. Ogungbesan, T. A. Adedosu & D. D. Amos · Asian Journal of Physical and Chemical Sciences · 2026

Previous organic geochemical studies of the hydrocarbon source potential of the Upper Cretaceous Fika and Gongila shales have mainly used bulk geochemical techniques, whereas the contribution of molecular biomarkers to source-rock characterisation remains relatively limited. Ther...

Simulation-based Design of a Compact Wearable Antenna for Microwave Imaging of Bone Fractures in Osteoporotic Patients

P. A. Amoo, G. O. Ogungbesan, O. Olabisi & S. O. Areo · Asian Journal of Research and Reviews in Physics · 2026

Osteoporotic bone fractures require safe, repeatable monitoring approaches, particularly when repeated exposure to ionising radiation is undesirable. This study presents the simulation-based design of a compact wearable microstrip patch antenna for microwave assessment of bone-fr...
