Abstract Parameters of supramolecular structure of celluloses isolated from various natural sources have been studied, such as type of crystalline allomorph, crystallinity and amorphicity degrees, interplanar distances and specific volume of crystalline unit cells, as well as sizes and area of specific surface of crystallites. It was found that in the sequence of various CIβ […]

Study of the Adsorption of Heavy Metals on Clay Activated
Abstract Presence of heavy metals in the aquatic systems has become a serious problem. As a result, there has been a great deal of attention given to new technologies for removal of heavy metal ions from contaminated waters. In this study, we carried out the elimination of the ions of cobalt, cadmium and manganese in […]
A Review on Synthetic Methods of Nanostructured Materials
Abstract Interest in Nanoscience and Nanomaterials has remained unabated and has attracted so much attention in recent times. New advances both in the preparation and device fabrication have emerged due the development of nano and material sciences. Scientists from different fields of research such as biologists, chemists, physicists, material scientists, pharmacists and engineers are involved […]
Proximate and Ultimate Analysis of Walnut Shell as a Potential Low Cost Adsorbent using Different Activating Agents (KOH and H2SO4)
Abstract The need to eradicate toxic or unwanted elements present in the environment has given rise to the use of low cost adsorbents. The feasibility of walnut shell as a low cost adsorbent was analyzed via Proximate and Ultimate analysis using two chemically activated agents (KOH and H2SO4). The walnut sample was carbonized at a […]
Computational Evaluation of the Druggability and Biological Activity of Iodo-1,4-dihydropyridine Derivatives
Abstract Several successful antihypertensive medicines already in clinical use are derivatives of 1,4-dihydropyridine (1,4-DHP). They are considered the most potent calcium channel blockers of which, nitro-, chloro- and fluro-1,4-DHP derivatives have been extensively investigated for biological activity [1-5]. Nevertheless, iodo-1,4-DHP derivatives have not received enough attention. Our aims were to evaluate the druglikeness and bioactivity […]
Evaluation of Polycyclic Aromatic Hydrocarbons of Some Woods, Charcoals and Coal of Nasarawa State, Nigeria
Abstract Lafia-Obi coal, woods and charcoals from Keffi, Marke and Shamagay in Nasarawa State were evaluated for the presence of Polycyclic aromatic hydrocarbons (PAHs) using standard methods. Samples were saw-milled and pulverized to 200-mesh size and solvent extracted using n-hexane and dichloromethane at 80oC and 30oC for 48 h and fractionated in alumina column. Both […]
Analysis of Cu and Pb Contamination of Soil and Earth Worm Casts in Kwande Metropolis, Benue Sate-Nigeria
Abstract Soil and Earthworm casts from waste dumpsite around mechanic village in Kwande Local Government were collected and analyzed for Copper (Cu) and Lead (Pb) using Atomic absorption spectrophotometer. The analysis of soil and cast sample around mechanic village gave the concentration (mg/Kg) of copper as 5.21, 5.20, 5.10,5.02, 4.18 and 5.20, 5.19, 4.99, 4.81, […]
Metabolites Composition of Garcinia kola Extract as Potential Substitute for Isomerized Hop Extract in Beer Brewing
Abstract The potential of methanoilc extract of Garcinia kola (bitter cola) as substitute for isomerized hop extract in beer brewing was evaluated. The number of metabolites in each extract was investigated using Thin Layer Chromatography (TLC) technique. The relative proportion of each metabolite in the two extracts was investigated using Gas Chromatography – Mass Spectrometer […]
Sorption Kinetics of Cr(lll), Cd(ll) and Pb(ll) ions from aqueous solution by Monkey bread (Piliostigma thonningii) seed pod
Abstract Adsorbents of natural origin are widely used for industrial wastewater treatment in order to replace currently costly methods of heavy metals removal from solutions. For that purpose, the potential of an agricultural waste, Piliostigma thonningii pod as an adsorbent in the removal of Cr(III), Cd(II) and Pb(II) ions from aqueous solution was investigated. The […]
