    Abstract: This work is aimed at comparing the adsorption capacities of the activated carbons derived from coconut shell and pineapple peels using Safranin-O as adsorbate. Physical activation method was employed to generate the activated carbons using phosphoric acid (H3 PO4) as activating agent. Batch adsorption experiment was employed for the adsorption pro...

    Abstract: The susceptibility of metals to corrosion due to attack by their environment has necessitated the search for corrosion inhibitors which can protect the metals and also be friendly with the environment. In this research, corrosion inhibition study of Terminalia ivorensis leaves extract on galvanized and mild steel in 1.0M Sulphuric acid was carried ... Show More

    Abstract: The values of the Gibbs function of a system with C components create a 2‑dimensional topological manifold that is piecewise smooth and continuous. Each of the C+2 smooth elements of such a manifold represents the states of a phase within the system. The elements are glued together along the C types of phase transformation lines, which converge to ... Show More

    Abstract: In this paper, the possibility of predicting values apparent activation energy for viscous flow in five-membered naphthenes by the calculation method, namely, using the two-parameter dependence of structural descriptors, is investigated. We explore structural descriptors of the molecular graph, namely, a topological index and the sum of eigenvalues... Show More
