The aim of this study was to investigate the effects of Magnesium Oxide (MgO) nanoparticles on the performance of black-seeded beniseed. The black-seeded variety was obtained from the seed stores of the Botany department of Joseph Sarwuan Tarka University, Makurdi, Benue state. MgO nanoparticles were applied to each variety at concentrations of 20ppm, 40ppm, 60ppm, 80ppm, and 100ppm, along with salt and NPK. The results of the seed germination test on day 7 showed that the nano treatment at a concentration of 100ppm improved the number of emergence (3), average length of plantlet (4.85), and plant vigor (5) compared to the control (2.5, 4.75, and 4), respectively. However, the highest nano concentration (50ppm) for average root length had a value (2.25) that was lower than the control (7). Regarding growth parameters, the nano concentration of 20ppm improved the number of leaves (84.0±42.5) and the number of branches (7.60±5.90) compared to salt (65.00±15.98 and 7.500±1.768) and NPK (65.00±6.36 and 6.860±1.264), respectively. An 80ppm concentration improved plant height (70.00±15.80), leaf length (15.30±4.21), and stem diameter (5.00±0.00) compared to salt (84.40±18.53, 20.10±3.96, and 5.00±0.00) and NPK (89.00±6.60, 15.80±4.21, and 5.00±0.00). Statistical analysis indicated a significant difference in leaf length and stem diameter only. For reproductive parameters, 20ppm and 60ppm improved the number of pods (12.60±16.20) and the number of flowers (42.60±4.22) compared to salt (11.40±10.43 and 41.80±2.59) and the number of flowers with NPK (39.20±5.67), respectively. However, the number of pods for NPK had the highest value (18.20±8.93). Only the number of flowers showed a significant statistical difference among the treatments. Regarding plant biomass, 20ppm improved wet biomass (43.86±15.00) but not as much as salt (55.34±14.98) and NPK (106.5±138.5). An 80ppm concentration significantly improved dry biomass (16.04±4.73) compared to salt (15.50±2.58) and NPK (15.34±6.59). Statistical analysis indicated a significant difference in dry biomass. Results for seed germination showed that MgO nanoparticle treatment improved all seed germination parameters, including average root length. Additionally, MgO nanoparticle treatment improved the overall performance of black-seeded beniseed compared to salt and NPK. Therefore, the use of MgO nanoparticles is recommended for black-seeded beniseed cultivation to enhance seed germination and overall performance.

Although employment of fossil fuels for power generation may have seemed inevitable, fuel cells since have emerged; however, have been a sustainable energy means. Thanks to their several types, different characteristics and great performance, fuel cells have found a wide range of applications. Among fuel cells, solid oxide fuel cells have been harnessed for the synthesis of valuable chemicals without compromising energy production in a cogeneration setup. It is possible to generate electricity while simultaneously producing syngas with different compositions. This is accomplished through the dry reforming of various fuels, such as CH4-CO2, pure CH4, and other hydrocarbon fuels, aided by selective oxidation. Although that being said, solid oxide fuel cells not only demand difficult operating conditions, but their components such as the cathode, electrolyte, anode, interconnects and sealants must also exhibit several essential bespoke properties. Another significant hurdle to the wider adoption of fuel cells, especially solid oxide fuel cells that utilize hydrogen as a key fuel, is the absence of a comprehensive infrastructure for the production, storage and distribution of hydrogen.

The ability of several hydroxyquinolines to inhibit aluminum corrosion and the effect of hydroxyls at 6, 7, and 8 positions on quinolines in hydrochloric acid were experimentally studied by weight loss, EIS, and PDP. To promote weight loss, 6-hydroxyquinoline (6-OHQ), 7-hydroxyquinoline (7-OHQ), and 8-hydroxyquinoline (8-OHQ) were used under different mass and temperature conditions at different HCl concentrations. The adsorption properties of these inhibitors proved to be reliable. Both chemical and physical mechanisms were significant in the Longmuir isotherm. In comparison, 7-hydroxyquinoline performed better than 6-hydroxyquinoline in terms of corrosion inhibition percentage, mass loss, inhibition efficiency, and surface coverage measured by weight loss. Under identical conditions, 8-hydroxyquinoline performed the worst in terms of corrosion inhibition. The inhibition process proceeded more rapidly in each system via first order kinetics. The surface morphology and functional groups were examined by SEM and FTIR before and after the corrosion study. The weight loss and Nyquist plots from the impedance data and parameters both showed the same behavior. The Tafel plot parameters and polarization data both show the same trend. The EIS, PDP, and weight reduction results are relatively consistent. Although each molecule exhibited excellent corrosion inhibition performance, the 7-OHQ molecule is superior to the other two molecules in inhibiting aluminum corrosion.
