Summary: Proton-conducting gel electrolytes, specifically phosphoric acid, show high proton conductivity and specific capacitance for supercapacitors, especially when combined with reduced graphene oxide symmetric electrodes. By confining phosphoric acid electrolyte within a liquid crystal gel matrix, the specific capacitance can be further increased through the formation of mesophase structures. The potential application of this LC gel electrolyte in asymmetrical pseudocapacitors for automotive use to enhance energy density is also discussed.

Summary: This study synthesized urea nitrogenated activated carbon (N-ACU) from oil palm empty fruit bunches and investigated its performance as a supercapacitor electrode. The results showed that the urea to hydrochar impregnation ratio affected the characteristics of N-ACU and the performance of supercapacitors. Urea nitrogenated treatment on activated carbon reduced resistance and maintained the stability of the supercapacitor. This study suggests that synthesizing nitrogenated activated carbon from biomass waste is a promising method for producing electrode materials.

Summary: Screen-printing inks containing different carbon morphologies and concentrations were studied for their effects on print topography and conductivity. It was found that smaller carbon black particles had better conductivity but higher ink viscosities and elasticities. Increasing carbon concentration led to increased film thickness and roughness. However, beyond a certain point, further increase in carbon concentration resulted in particle agglomerations and ink separation issues. A combination of shear rheology and high-speed imaging could be used to optimize the carbon concentration of screen-printing inks.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
