The effects of particle size and particle size distributions of three clay samples, on their modulus of rupture were studied. The three clay samples were collected from natural clay deposits at Nsu; Ohiya- Umuahia; and Awo-Omamma all in south eastern Nigeria. The particle size … Continue Reading

Electrochemical capacitors (ECs) or Super capacitors (SCs) are energy saving devices which have excellent properties that include high power density, long cycle life, low temperature sensitivity and low maintenance cost. However, these devices have lower energy densities than conventional batteries. To improve on its energy density, SnO2… Continue Reading
Equal channel angular pressing (ECAP) has over the years been used as a severe plastic deformation method to refine the grains and improve the strength of various metals. Even though this has been largely successful, research over the years has tried to increase the amount of strain induced in the materials used during this process so as… Continue Reading
This work investigates the optical properties of glass prepared using Otamiri Silica sand mixed with analytical grade oxides as a function of their composition. Three batches were prepared with Phosphorus as the main variable of the SiO2-Na2OB2O3-CaO-ZnO glass system. The glass was melted in a ceramic crucible with a lid and the glasses… Continue Reading
