Triggering the anionic redox reactions at high voltage is an effective approach to boost the capacity of Li-rich layered oxides. However, the irreversible lattice oxygen release at high voltage and sluggish ion kinetics remain conundrums. Herein, a surface modifying coupling defect engineering strategy is proposed to improve the reversibility of anionic redox reactions and ion diffusion efficiency in Li-rich layered oxides. A LiNbO3 surface modification acts as an effective physical barrier to suppresses lattice oxygen release, thereby improving cycling stability of Li-rich layered oxide. Further, the oxygen vacancies in the LiNbO3 coating enhances the ion transport kinetics, strengthening rate capability. After 500 cycles, a high capacity retention of 83.3% can be achieved for the obtained cathode materials (CV-LLO) at 5 C, much higher than that of the pristine materials (LLO, 52.3%). Moreover, CV-LLO delivers a capacity of 169.9 mAh g-1 at 5 C, which was 65.1% of the capacity at 0.2 C, much higher than that of the pristine LLO (85.6 mAh g-1, 33.7%). This study provides insights into the construction of Li-rich layered oxide cathode with highly reversible anionic redox reaction and highly cycling stability for Lithium storage.

Korean researchers have secured flexible electronic skin technology that can be fabricated directly in the field. This achievement has further increased the feasibility of commercializing electronic skin for use in various fields, including robots and wearable devices. Electronics and Telecommunications Research Institute (ETRI) announced that, in collaboration with the research team of Professor Ahn Jun Seong from the Department of Control and Instrumentation Engineering at Korea University's Sejong Campus, it has developed an in-situ process-based electronic skin fabrication technology capable of producing large-area multimodal sensors without a cleanroom, a dedicated semiconductor clean-processing facility.

A research team from Jiangnan University has developed an engineered Escherichia coli strain capable of producing orotic acid at unprecedented levels using an innovative antibiotic-free plasmid stabilization system. The study reports a final titer of 150.48 g/L with a yield of 0.63 g/g glucose in fed-batch fermentation.

Inspired by the multimodal perception characteristics of insect antennae (for force, temperature and gas), the ECUST interdisciplinary team developed the Electronic Multifunctional Sensing Antenna (EMSA)—a flexible thin-film self-decoupling multimodal sensor fabricated via a maskless laser direct writing process. The sensor realizes intrinsic decoupling of temperature and strain, as well as simultaneous thermo-mechanical-gas trimodal monitoring, with four core technological breakthroughs.
