Mass Concentration and Size-distribution of Atmospheric Particulate Matter in Plateau State, Nigeria

E. C. Hemba, E. A. Trisma & T. J. Ikyumbur · International Journal of Environment and Climate Change · 2019

The mass concentration and size distribution of atmospheric particulate matter (PM) was measured in three major towns in Plateau state. The CW-HAT200 PM2.5, PM10 dust particle counter was used to measure the particle size in each major location within Jos, Shendam and Pankshin. T...

Calculation of Cohesive Energies of 3-D Bismuth Selenide (Bi2Se3) and Bismuth Antimony BiSb Topological Insulators: DFT Study

E. C. Hemba, T. J. Ikyumbur, E. A. Trisma, F. Gbaorun & F. Aungwa · Asian Journal of Research and Reviews in Physics · 2022

The cohesive energies of 3-dimensional (3-D) topological insulators bismuth antimony (BiSb) and bismuth selenide (Bi2Se3) were calculated. The Fritz Haber Institute Ab-initio molecular simulations (FHI-aims) code was employed for this calculation.  The output files of the FHI-aim...
