Oxyhydrogen gas (HHO) was formed by water electrolysis using an alkaline electrolyser at 0.5 litres per minute. Experiments were run at engine speed of 3000 rpm and load variation.

Self-healing compatibility and mechanical flexibility of biomass-derived electrolyte can enhance battery safety, durability and stability by improving electrochemical performance for EV application which can improve driving range. Integration of components derived from biomass is necessary to enhance driving range, durability and safety of EV.

Exponential incremental cost (IC) consensus and supply-demand equilibrium are used for attaining a fast convergence to an optimal solution. The exponential convergence analysis under directed graphs takes into account a Lyapunov function. The proposed approach considers the uncertainty in renewable sources which has been tackled by incorporating the weather information and by considering grid digitization via smart meters, advanced communication architecture, GPSs-based clock synchronization and cumulative information of generator data. Furthermore, this study introduces renewable energy sources (RESs) into microgrids, highlighting their variability and intermittent nature and accounts for a robust solution for the energy dispatch. Moreover, an assessment for the energy production, emission reduction, and operation cost analysis has also been provided for the eastern part of Saudi Arabia, based on uncertain weather conditions. Simulation testing validates the efficacy of the suggested strategy for an IEEE benchmark networked system.

The increase in global population comes with an increase in the consumption of pharmaceuticals and personal care products (PPCPs), and correspondingly, an increased likelihood that they will occur in the global waterways. PPCP occurrence poses a hazardous risk to the water ecosystem and by extension the environment as a whole, whereas their exposure to PPCPs constitutes a health risk to humans and aquatic wildlife. Thus, the application of water treatment technologies that effectively remove PPCPs is crucial. The currently applied methods in existing treatment plants do not effectively remove PPCPs. In fact, the scientific community has concluded that single technology treatment cannot provide sufficient PPCP removal. Hence, there has been growing research that focuses on combining advanced treatment technologies into hybrid systems for more effective removal efficiency. This work presents an in-depth review of this research, critically assessing the available information and identifying the areas lacking. The literature indicates that while there is a significant number of studies in the field, there is a notable lack of data that pertains to the economic considerations and environmental sustainability of hybrid technologies. Furthermore, most studies address a very narrow selection of PPCPs, overlooking the impacts of PPCP cocktails which may alter system performance and removal in undetermined ways.

A total of 36 experiments were designed, with factors set at more than three levels to account for quadratic behaviors. Computational fluid dynamics (CFD) analyses were conducted in ANSYS 2024 R2 to calculate the torque generated in each case. An analysis of variance (ANOVA) was performed for the results of each experiment, identifying the radius ratio as the factor exerting the greatest effect on torque generation. Five regression models were developed in the R environment, and variable coefficients were calculated through ANOVA. The best regression model was identified using the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC). The model with the best fit for efficiency prediction was optimized using a response surface, where three axes represented the analyzed variables and the response variable was visualized as a color gradient. By iterating the regression model within the studied factor levels, the optimal parametric configuration for the hybrid turbine was determined to be 0.2 for the radius ratio, 50° for the coupling angle, and 2.2 for the TSR, resulting in an efficiency of 55.19%.
