In this paper, we present the synthesis of C@FeO-MoO binary composite were prepared through the facile hydrothermal process. The ultrasonic aided adsorption efficacy was evaluated by studying triphenylmethane dye's adsorption potential. The ultrasonic aided adsorption capacity towards crystal violet was 993.6 mg/g, which is remarkably higher and best fitted with the Langmuir isotherm model and followed pseudo-second-order kinetics. The electrochemical studies working electrode have been prepared with 80 wt% active material, 10 wt% carbon black, and 10% polyvinylidene difluoride to evaluate energy storage characteristics. The C@FeO-MoO demonstrated an excellent specific capacitance of 40.94 F/g with better retention and stability, making it a potential cathode material for next-generation electrochemical energy storage devices.

Microgrid systems have evolved based on renewable energies including wind, solar, and hydrogen to make the satisfaction of loads far from the main grid more flexible and controllable using both island- and grid-connected modes. Albeit microgrids can gain beneficial results in cost and energy schedules once operating in grid-connected mode, such systems are vulnerable to malicious attacks from the viewpoint of cybersecurity. With this in mind, this paper explores a novel advanced attack model named the false transferred data injection (FTDI) attack aiming to manipulatively alter the power flowing from the microgrid to the upstream grid to raise voltage usability probability.

Cubic silicon-carbide crystals (3C-SiC), known for their high thermal conductivity and in-plane stress, hold significant promise for the development of high-quality (Q) mechanical oscillators. We reveal degeneracy-breaking phenomena in 3C-phase crystalline silicon-carbide membrane and present high-Q mechanical modes in pairs or clusters. The 3C-SiC material demonstrates excellent microwave compatibility with superconducting circuits.

The removal of selenite (SeO) from water is challenging due to the risk of secondary pollutants. To address this, we developed RuO-based nanocatalysts on the titanium plate (RuO/TP) for direct electrochemical reduction of Se(IV) to elemental selenium [Se(0)]. Optimizing Sn doping in RuO nanoparticles to induce charge redistribution enabled the RuSnO/TP catalyst to achieve ∼90% Se(IV) removal across concentrations of 0.

In order to overcome harsh working environments and meet eco-friendly demands, the development of environmentally tolerant and recyclable hydrogels is necessary. Herein, multifunctional conductive hydrogel was successfully constructed by introducing starch into polyvinyl alcohol (PVA)/glycerin (Gly)/lithium chloride (LiCl) hydrogel. Starch is rich in active sites (-OH groups) that provide a variety of physical interactions for the construction of polymer hydrogels.

Driven by sustainable development goals and carbon neutrality worldwide, demands for both renewable energy and storage systems are constantly increasing. However, the lack of an appropriate approach without considering renewable intermittence and demand stochasticity will lead to capacity oversizing or undersizing. In this study, an optimal design approach is proposed for integrated photovoltaic-battery-consumer energy systems in the form of a m-kWp-kWh relationship in both centralized and distributed formats.
