Summary: Biomass-derived carbons are widely studied as cost-effective energy storage materials with high performance due to their high specific surface area and the effectiveness of strategies like increasing surface area and introducing heteroatom doping. Porous carbon materials derived from sorghum stem show significantly higher specific capacitance after KOH activation, demonstrating their versatility in applications like capacitive deionization. The performance trend observed in both supercapacitors and CDI for all carbon samples is consistent due to the exploitation of carbon material's electrostatic double-layer capacitance behavior.

Summary: The crevice corrosion of N80 carbon steel in acidic NaCl solution can occur with or without O-2, with O-2 enhancing the cathodic reaction processes outside the crevice. However, its effect on the cathodic reaction processes inside the crevice is not significant. The galvanic corrosion effect between inner and outer steels can be enhanced by O-2, leading to increased crevice corrosion.

Summary: The effect of electrolyte presence form on the corrosion evolution and stress corrosion cracking (SCC) behavior of E690 steel in the simulated marine environment was investigated. The steel exhibited the highest corrosion rate in splash environment and the lowest corrosion rate in immersion environment due to differences in oxygen availability, rust layer property, and scour stress. γ-FeOOH dominated the rust formed in atmospheric environment, while Fe3O4 prevailed in the splash environment. The steel corroded in splash environment showed the most severe SCC degradation with high pit number density, high maximum pit depth, and high cathodic reaction activity.
