Summary: Aluminum-sulfur batteries have become the most prominent battery technology due to their high theoretical capacity, eco-friendliness, economics, and abundance of aluminum as well as sulfur. Recent research has focused on different types of carbon as hosts for sulfur and controlling the aluminum polysulfide shuttling effect. Significant progress has been made in finding suitable electrolytes theoretically and experimentally, with some success using ionic liquid electrolytes. However, challenges such as oxide layer formation on aluminum, low cyclic stability, and high cost of electrolytes still need to be addressed to make aluminum-sulfur batteries a competitor to lithium-ion batteries.

Summary: The demand for high-capacity energy storage has led to extensive research on supercapacitors, which require high power output and faster charging. Graphene oxide (GO) and reduced GO (RGO) have been widely used for supercapacitor preparation, but their bilayer combination has not been studied. In this work, GO/RGO bilayer electrodes on fluorine-doped tin oxide (FTO) substrates were synthesized and their performance was evaluated. The FTO-GO-RGO electrodes showed the best areal capacitance performance, while the highest specific areal capacitance was achieved with FTO-GO-RGO as the anode and FTO-GO-GO as the cathode. The unique physicochemical properties of the GO/RGO bilayer were attributed to inter-/intralayer molecular interaction. This study emphasizes the importance of exploring multilayer GO/RGO electrode fabrication methods for high-capacity supercapacitors.

Summary: This paper conducts a failure analysis on a leaking pipe jet nozzle and discusses the results in detail. The investigation includes visual observation, microscopy, 3D scanning, spectroscopy, and measurements. Numerical simulations are also performed to investigate the root cause of the failure and find an alternative design to prevent leaks. The study finds that increased turbulence and multiple impacts of particles on the wall lead to leaks and cracks in the pipe jet nozzle. Moreover, the proposed alternative design shows a significant reduction in erosion rate compared to the failed pipes.
