In the MnO₂@MG composite, the presence of modified graphite (MG) restricts the degree of freedom of MnO₂ growth, resulting in the formation of smaller MnO₂ structures and avoiding the accumulation and aggregation of MnO₂, which helps to improve the interface charge transport of composite electrodes. Meanwhile, the MG could effectively slow the structural collapse of MnO₂ during charging/discharging and improve the conductivity of MnO₂. Based on the synergistic core–shell structure, the AZIBs employing MnO₂@MG exhibit superior capacity (332.0 mA h g⁻¹ at 100 mA g⁻¹ over 300 cycles), excellent rate capabilities (208.1 mA h g⁻¹ at 500 mA g⁻¹), and outstanding cycling performance (48.1% capacity retention after 2000 cycles) at high current density.

This study introduces a novel parameter identification approach using the marine predators algorithm (MPA), applied to a Shepherd model for EV applications. The proposed technique was validated under various dynamic test conditions, including the urban dynamic driving cycle (UDDC), the new European driving cycle (NEDC), and the worldwide harmonized light vehicles test procedure (WLTP). The MPA-based method systematically identifies optimal parameters, achieving a voltage error of 2.743 × 10⁻³, a state of charge (SOC) error of 0.7693 × 10⁻³, and a root mean square error (RMSE) of 8.37 × 10⁻³ between the model and real data. Compared to other optimization techniques, the MPA demonstrated superior performance, achieving an optimization efficiency of 97.69%. These results validate the robustness and reliability of the method for accurately capturing battery dynamics under realistic driving conditions.

Therefore, this paper closes the knowledge gap by assessing the influence of environmental technology (EVT), economic policy uncertainty (EPU), renewable energy transition, and urban transition on CEM. Moreover, the study investigated the moderation effect of environmental governance on the interconnection between EPU and CEMs, incorporating historical data from 30 years ago (1990–2020). The research applied three econometric techniques, moments quantile regression, fully modified ordinary least square (FMOLS), and Driscoll and Kray standard errors (DSK), to ascertain the interaction among the research indicators. The study’s outcome established that (1) the switch to renewable or cleaner power supply, EVT, and governance improves ecological health. (2) Environmental policy uncertainty and urban transition disrupt ecological stability in the Arctic region. (3) Environmental government moderates the effect of EPU and CEM.

Traditional cooling methods face challenges of high energy consumption, motivating the need for innovative solutions. This study hypothesized that integrating Peltier modules into a pedestal fan could significantly enhance cooling efficiency while conserving energy. Investigating the shift from traditional to renewable energy systems for air conditioning (A/C) and ventilation is crucial for achieving sustainability and energy conservation. To meet the comfort standards set by ASHRAE, a study was carried out to design, construct, and assess the cooling efficiency of a bladeless pedestal fan employing Peltier modules. This study also examined how Peltier modules influence the efficiency of a conventional pedestal cooling fan. The experimental study was held in a 4 × 4 m room using two, four, six, and eight Peltier modules at external temperatures ranging from 43°C to 45°C, with indoor starting temperatures of 37°C. Each setup was tested three times and each experimental condition was tested for 60 min, with data recorded at 10-min intervals. The Peltier effect was utilized to cool water, which in turn cooled the air. The comfort zone was subsequently created using this cooled air. A regression analysis was employed to validate the results, with the cooling performance evaluated using standard error and confidence intervals. The energy savings were estimated by comparing the power consumption of the Peltier module-based fan to that of conventional pedestal fans and A/C units. The temperature reduction achieved was 4%, 12%, 18%, and 22% with the use of two, four, six, and eight Peltier modules, respectively.

This research examines the nonlinear impact of financial development on adopting renewable energies in 10 emerging countries facing geopolitical risks between 1985 and 2022. By employing two regime-switching approaches (panel threshold autoregressive (PTAR) and panel smooth transition autoregression (PSTAR)), the results indicate nonlinear correlations between domestic bank credit granted to the private sector and the adoption of renewable energies. The optimal threshold value of the PTAR model is 40.171, while those of the PSTAR model are 35.705 and 122.9. Below the thresholds of the PTAR and PSTAR models, financial development decreases the CREs. Beyond these thresholds, financial development promotes CRE through specific financial incentives, such as low-interest loans and tax credits for renewable energy projects, as well as the creation of specialized financial instruments, such as green bonds. Geopolitical issues have prompted governments to diversify their energy sources and intensify their investments in renewable energy to strengthen energy security and reduce dependence on the volatile fossil fuel markets.
