This work illustrates the production and characterization of metallurgical coke from Duduguru coal, Obi local Government Area of Nasarawa State, Nigeria. The analytical assessment of properties such as proximate analysis, elemental composition, and calorific value are very important to know the coking qualities of the coal. The proximate analysis showed that the moisture content, ash content, volatile matter, fixed carbon and calorific values of the coal are; 1.86%, 18.82%, 43.74%, 53.58% and 5405.15 Cal/g respectively. Based on the result of the proximate analysis, the coal is of good metallurgical coke quality from an industrial prospective and heat generation is to be considered. Elemental analysis shows that due to the low heavy metals, low sulfur content and ash content of the coal, utilization of the coal within a safe environment is feasible with just a little environment impact and make it suitable for blending with strong coking or caking properties.

In this study, magnetic sand and Crotalaria pallida gotten from Adamawa and Bauchi states of Nigeria, respectively, were mixed after treatment, and impregnated with kaolin using a wet impregnation method and the resulting material was characterized using scanning electron microcopy (SEM), X-ray fluorescence (XRF) and X-ray diffraction (XRD). The result of XRF analysis revealed the existence of a number of dopant-like constituents in the sample, which substitute parts of important atoms in the spinel structure, however, not forming individual phases. The SEM micrographs displayed pore structures with high surface area consistent with effective catalyst materials. XRD analysis confirmed crystalline phases of the hybrid material showing typical diffraction peaks of kaolinite minerals (Al2Si2O9), Muscovite (Al12FeSi12K4NaRbH16O48), quartz, Si3O6 Calcite (Ca6C6O18) and Halite (Na4Cl4) and the average crystallite size was determined to be 75.30 nm.

The binding of 1-chloro-3-(2-methyl-5-nitro-1H-imidazole-1-yl) propan-2-ol (Ornidazole) to human serum albumin (HSA) was studied by fluorescence and UV-visible spectroscopy. Interaction of ornidazole (OR) with HSA was identified by Stern-Volmer and Van’t Hoff equations. The binding constant, Kb and the thermodynamic parameters, ∆H, ∆S, and ∆G at different temperatures were calculated by several equations. Data shows that the fluorescence quenching mechanism of HSA with ornidazole may occur via static quenching. The thermodynamic parameters showed that van der Waals interactions and hydrogen bonds are the major forces for the interaction of ornidazole with HSA. The spectral changes of synchronous fluorescence suggested that both the microenvironment of OR and the conformation of HSA concerning their concentrations have changed during binding.

The potential of yam peels for bioethanol production was investigated through an understanding of their compositional profile. The yam peels dried powder was subjected to X-ray diffraction analysis, and it was examined for proximate and biochemical composition. The result of the biochemical analysis of the yam peels showed the following: holocellulose (57.93 %) [cellulose (29.02 %) + hemicellulose (28.91 %)], and lignin (27.43 %), while the proximate analysis showed the following: moisture (11.11 %), ash (5.93 %), and volatile matter (68.4 %). Consequently, the X-ray diffraction pattern shows the presence of amorphous and crystalline region in the sample. The result showed that the yam peels possesses low lignin and high holocellulose content. This study indicate that the yam peels are potential candidates for bioethanol production.

The proximate compositions of the seeds and fatty acid contents of the seed oils of the three varieties of Capsicum (pepper) species fruits – sweet, bell and bird pepper – have been determined using standard AOAC methods. Their proximate compositions gave moisture contents as 82.54%, 83.32% and 84.74% for bird, sweet and bell peppers respectively. Other proximate values in the various pepper samples ranged as follows: crude fat 1.52%–2.21%, crude protein 2.64%–3.51%, crude fibre 2.72%–4.71%, ash contents 1.62%–3.03% and carbohydrate contents 4.52–6.96%. The order of abundance of the fatty acids were linoleic > oleic > stearic > palmitic in each sample. All the other fatty acids, except myristic acid in bell pepper seed oil, had values lower than 1.00% in all samples. The total unsaturated fatty acids predominated the total saturated ones with values ranging from 79.23% in bird pepper to 82.33% in bell pepper. The total polyunsaturated fatty acids ranged from 57.80% in sweet pepper to 66.50% in bell pepper while the total essential fatty acids ranged from 57.78% in sweet pepper to 66.00% in bell pepper. The total unsaturated/saturated (P/S) ratio was highest in bell pepper, making it the most nutritionally useful of them all.

Most recently, there has been an increase in the use of herbicides to control weeds by farmers in Pankshin Local Government Area (LGA), Plateau State. The use of herbicides in farming activities has significantly provided more hope and assurance for sustainable food security in most countries of the world as bumper harvest have always been recorded.in its usage however the residues of the herbicides after successive accumulation by the years could be a threat to humans and other non-target organisms after they have performed their primary roles. From an interview with the farmers it was discovered that glyphosate, paraquat dichloride and 2,4-dichlorophenoxy acetic acid are mostly used within the study area which are hazardous and should be handled with utmost care. Soil samples were obtained from Bumnan, Bwarak, Larpya and control. The samples were pretreated and subjected to the following analysis: Extractions, crystallization and recrystallization with the aid of acetone, dichloromethane, hexane and methanol as solvents. Physicochemical properties of the soil samples were determined and the following range of results were obtained: pH 5.2-5.3, % organic matter 4.02-8.23, EC 10-50 µS/cm, residual moisture 0.5-3.0% and CEC 16.52-29.63cmolKg-1. GC analysis was carried out on the crystals and extracts to determine the herbicides concentrations and the following results were obtained in mg/kg: Bumnan – 0.005 and 0.026, Bwarak- 0.004 and 0.008, Larpya- 0.015 and 0.033 and control 0.002 and 0.007 concentrations of 4, 4- bipyridine and 2,4-diphynoxyacetic acid respectively.
