Summary: Aluminum ion batteries (AIBs) are currently gaining attention due to their high capacity, low cost, and safety, but their practical applications are limited due to the lack of suitable cathodes and complex energy storage mechanisms. Polyaniline, a type of conducting polymer, shows promise but has not been extensively studied for AIBs. In this study, emeraldine base polyaniline (PANI) was synthesized and used as a cathode in an Al/PANI cell with a chloroaluminate ionic liquid electrolyte. The PANI cathode exhibited better electrochemical performance, higher discharge specific capacity, and improved capacity retention compared to protonated polyaniline cathodes, due to a novel conversion process and reversible doping of chloroaluminate ions in the PANI-AlCl3 complex. These findings contribute to the development of high-performance AIBs with conducting polymers as cathode materials and provide insights into their charge storage and reaction mechanisms.

Summary: In this study, graphene oxide (GO) was functionalized with poly (amido amine) (PAMAM) to produce GO-PAMAM nanocomposite, which was embedded in polysulfone membrane matrix produced by phase inversion. The synthesized nanocomposites with abundant -OH and -NH2 groups improved the hydrophilicity and pore size of the membrane, leading to a 1300% increase in pure water permeation flux compared to the pristine PSF membrane, reaching a maximum of 124.5 LMH/bar. The membrane maintained a high BSA rejection rate of 99% with a flux recovery rate of 55%. Despite the low flux recovery rate, the significant improvement in pure water permeation flux while maintaining high BSA rejection makes the produced membrane suitable for future ultrafiltration applications.

The results demonstrate that MIL-101(Fe) has excellent adsorption capacity for silicic acid, with a maximum adsorption capacity of 220.1 mgSiO(2)center dot g(-1). The adsorption is consistent with the pseudo-second-order equation and Freundlich equation. Additionally, a simulated anti-scaling experiment shows that MIL-101(Fe) has great potential for mitigating silica scale in RO systems.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
