Summary: A new green process was developed to efficiently produce high quality N-acetyl-L-cysteine (NAC) through organic synthesis, electrochemical reduction, and electrodialysis technology. The process avoids racemization and oxidation of intermediate products, achieves impurity removal, desalination, and recycling of electrolyte, and significantly reduces waste discharge. Pilot scale test showed a total yield of 73.1%, electrochemical yield of 96.2%, and energy consumption of 2.56 kW center dot h kg(-1). Environmental and tech-economic analysis demonstrated the process's advantages of mild reaction conditions, short synthesis steps, high product quality, and low waste emissions. This novel process is efficient, economical, environmentally friendly, and suitable for industrial production.

Summary: This study proposes a multifunctional additive, cysteine, for stabilizing zinc anode and addressing the instability issue in aqueous zinc ion batteries. Experimental and theoretical analysis demonstrate that the multiple polar groups of cysteine can strongly interact with Zn2+ and Zn metal, enabling the reconfiguration of solvation shell and anode/electrolyte interface. The synergistic effect of this multifunctional additive effectively inhibits dendrite growth and side reactions, resulting in a more stable zinc anode.

Summary: Designing an efficient electrode-electrolyte interface for H2O2 electrosynthesis is challenging. However, adding dimethyl sulfoxide (DMSO) to the electrolyte can improve the selectivity and activity of H2O2 production. The formation of hydrogen bonds between DMSO and water at the electrode-electrolyte interface reduces water dissociation, leading to improved selectivity of H2O2 synthesis. This work highlights the importance of regulating the interfacial hydrogen-bond environment for enhancing electrochemical performance.

Summary: Aqueous magnesium air batteries have the advantages of high theoretical energy density, inherent safety, and low cost. However, the practical energy density is limited by the hydrogen evolution corrosion of the magnesium (Mg) anode in conventional sodium chloride (NaCl) electrolyte. In this study, the hydrogen evolution reaction on the Mg anode surface is suppressed by using sodium acetate (NaAc) electrolyte, resulting in uniform anodic dissolution behavior of Mg without localized corrosion. The addition of acetate ions (Ac-) effectively prevents the breakdown of the passive film on the Mg anode, suppressing the anodic hydrogen evolution during discharge. This approach significantly improves the utilization efficiency of the Mg anode and boosts the specific energy of the Mg air battery. The practicality of NaAc electrolyte is confirmed in a commercial Mg air battery, providing a simple and scalable solution for high-performance Mg air batteries.

Summary: A low-molecular-weight supramolecular gel electrolyte (SGE) has been successfully developed for quasi-solid-state supercapacitors (QSSCs), which shows comparable performance dependence on electrode thickness as bulk electrolyte solutions. The high ionic conductivity and good wettability of the SGE contribute to its effective filling of thick porous activated carbon electrodes.

Summary: As an important carbon-neutral energy carrier, green hydrogen produced through water electrolysis using renewable electricity has gained global attention. Polymer electrolyte water electrolyzers (PEWEs) have the potential to play a key role in the green hydrogen market due to their superior performance. However, the slow progress in the development of the membrane electrode assembly (MEA), an essential component of PEWE, hinders the advancement of PEWEs. This review discusses recent progress in MEA materials and design strategies, focusing on cost, activity, and stability of catalysts, distribution and thickness of ionomers, and ion transport efficiency of ion exchange membranes (IEMs). The effects of all components and interlayer interfaces on ions, electrons, and mass transfer in MEA, and consequently, the performance of PEWEs are analyzed. Perspectives on MEA development through optimization of catalyst activity and IEM stability, interface contact between adjacent components, and performance evaluation methods are proposed.
