The birth defects and fragile lattice result in the sluggish Li<sup>+</sup> diffusion kinetics and unfavorable structural degradation. Moreover, lattice strain, mechanical failures, surface reconstruction, and interfacial side reactions accelerate the decay process. Here, a proof-of-principle study of the lattice plainification (LP) strategy in a high-nickel NCM cathode is reported. The introduction of Al and Zr in transition metal layers by a wet chemistry and calcination method enables the simplification of the complex lattice structures to obtain an order phase and repair the various defects of NCM, thereby enhancing the lithium-ion transport. The modified LP-NCM exhibits a high initial discharge capacity of 157.3 mAh g<sup>-1</sup> with a capacity retention of 81% after 300 cycles at a 5C rate, significantly outperforming the pristine counterpart (50.9%). The LP-NCM/Gr pouch cells presented impressive cycling performance, achieving 80% capacity retention over 1000 cycles at 1C, which far surpasses the performance of the pristine NCM. Our method eliminates the rocksalt and disordered phases, and suppresses oxygen, lithium, and transition metal vacancies, as well as Li/Ni mixing. LP-NCM after cycling exhibits nanopores rather than cracks of pristine NCM. Our investigations reveal that the lattice plainification design approach flattens and toughens up the crystal lattice, which contributes to robust structural stability and improves the structure degradation, mechanical failures, and gas release.

In this study, we designed a heat-resistant and edible superhydrophobic coating by leveraging the unique and robust hierarchical structure of lycopodium spore powder (LSP) and utilizing natural low surface energy carnauba wax as the binder. The focus was to evaluate the hydrophobicity, heat resistance, and mechanical properties of the coating and to further demonstrate its application on liquid food packaging surfaces. The results confirmed that the lycopodium spore powder-carnauba wax superhydrophobic coating (LCW) exhibited excellent superhydrophobic properties (WCA > 150°, SA < 4°) and excellent self-cleaning function. It also has excellent anti-adhesion properties toward liquid foods with high viscosity and complex composition, such as honey, yogurt, <i>etc.</i> (it only takes 5170 ms and 2930 ms to completely slip on a surface with about 10° tilt, respectively). The incorporation of lycopodium spore powder notably enhanced the thermal stability of the coating, allowing it to retain a contact angle of 150° even after being subjected to high-temperature treatment at 120 °C for 2 hours.

However, conventional disinfection methods often produce toxic disinfection byproducts (DBPs) such as trihalomethanes (THMs) and haloacetic acids (HAAs), which pose significant carcinogenic and environmental risks. Cold atmospheric plasma (CAP) has emerged as a promising alternative disinfection approach that generates reactive species <i>in situ</i>, without the need for added chemical reagents. It utilizes reactive oxygen and nitrogen species (RONS), ultraviolet (UV) radiation, and transient electric fields to effectively inactivate a wide range of waterborne pathogens. CAP disrupts microbial membranes, damages nucleic acids, and induces oxidative stress, rapidly inactivating bacteria, viruses, and fungi. A notable advancement in plasma-based water disinfection is microbubble-enhanced cold atmospheric plasma (MB-CAP), which significantly improves plasma-liquid interactions. Microbubbles (MBs) act as efficient carriers for RONS, greatly increasing the gas-liquid interfacial area and enhancing the mass transfer of RONS. This results in faster removal of pathogens compared to conventional CAP systems. Furthermore, MB-CAP offers localized and targeted treatment capabilities, making it particularly suitable for decentralized water systems, hospital wastewater, and high-load industrial effluents. This review thoroughly examines the mechanisms of microorganism inactivation by MB-CAP, reactor configurations, MB generation techniques, and disinfection performance. This review also discusses key challenges such as energy efficiency, scalability, and regulatory compliance. Future research should focus on developing hybrid CAP systems, integrating renewable energy sources, and implementing real-time monitoring tools to optimize treatment efficacy.
