Selected Heavy Metals Levels (Cu, Cr, Cd, Pb, Fe) in Gwadabawa Lake, Sokoto State, Nigeria
Abstract: The main aim of this work was to determine the concentrations of some heavy metals, specifically Cu, Cd, Pb, Cr and Fe in Gwadabawa lake, Gwadabawa Local Government, Sokoto State using standard methods (atomic absorption spectroscopy) and materials of analytical grade. The results were analyzed. The range of Fe concentration was 0.01 ± 0.001 to 1.37 ± 0.3(ppm), and range of Cu concentration determined was 0.00 to 0.02±0.008(ppm). The range …

Raman Spectroscopy for The Determination of Relative Crystallinity of Carbon Fibers
Abstract: Analogous to X-ray diffraction technique, the light scattering technique discovered by Sir CV Raman has great potential in quantifying the crystallinity of new materials, like the highly crystalline pitch based carbon fibers (NX90 and NX100). For comparison the Raman spectra of polyacrylonitrile based carbon fibers (T700SC) were also recorded. From the Raman spectral analysis, it was found that the pitch based carbon fibers exhibit far far higher degree of crystallinity …

Optimal Dosage of Pumice in Lightweight Aggregate based Concrete
Abstract: Lightweight concrete (LWC) is a pioneering solution in the construction sector, characterized by its unique composition and versatile applications. Engineered with lightweight aggregates and additives, LWC achieves a significant reduction in dry density compared to conventional concrete, making it 23% to 87% lighter, with densities ranging from 300 to 1,840 kg/m³. This reduced weight makes LWC ideal for projects requiring load minimization, such as high-rise buildings and prefabricated elements. A …

Direct Synthetic Routes of MXenes and Their Application in Carbon Fiber Reinforced Plastics (CFRPs) As Supplementary Sizing Layer†
Abstract: Sized carbon fibers with a supplementary sizing layer of MXenes (synthesized via traditional MAX phases), bonded to carbon fibers (CFs) as well as the resin matrix via different kinds of physicochemical (van der Waals force, hydrogen bonding, covalent bonding) interactions enhanced the performance of the resulting carbon fiber reinforced plastic (CFRP) materials. This is because of the strong interface generated due to the appearance of MXene at the interface of …
