Sodium-ion batteries (SIBs), which serve as alternatives or supplements to lithium-ion batteries, have been developed rapidly in recent years. Designing advanced high-performance layered NaxTMO_(2) cathode materials is beneficial for accelerating the commercialization of SIBs. Herein, the recent research progress on scalable synthesis methods, challenges on the path to commercialization and practical material design strategies for layered NaxTMO_(2) cathode materials is summarized. Co-precipitation method and solid-phase method are commonly used to synthesize NaxTMO_(2) on mass production and show their own advantages and disadvantages in terms of manufacturing cost, operative difficulty, sample quality and so on. To overcome drawbacks of layered NaxTMO_(2) cathode materials and meet the requirements for practical application, a detailed and deep understanding of development trends of layered NaxTMO_(2) cathode materials is also provided, including high specific energy materials, high-entropy oxides, single crystal materials, wide operation temperature materials and high air stability materials. This work can provide useful guidance in developing practical layered NaxTMO_(2) cathode materials for commercial SIBs.

Tau truncation in the pathogenesis of Alzheimer's disease: a narrative review

Alzheimer’s disease is characterized by two major neuropathological hallmarks—the extracellular β-amyloid plaques and intracellular neurofibrillary tangles consisting of aggregated and hyperphosphorylated Tau protein. Recent studies suggest that dysregulation of the microtubuleassociated protein Tau, especially specific proteolysis, could be a driving force for Alzheimer’s disease neurodegeneration. Tau physiologically promotes the assembly and stabilization of microtubules, whereas specific truncated fragments are sufficient to induce abnormal hyperphosphorylation and aggregate into toxic oligomers, resulting in them gaining prion-like characteristics. In addition, Tau truncations cause extensive impairments to neural and glial cell functions and animal cognition and behavior in a fragment-dependent manner. This review summarizes over 60 proteolytic cleavage sites and their corresponding truncated fragments, investigates the role of specific truncations in physiological and pathological states of Alzheimer’s disease, and summarizes the latest applications of strategies targeting Tau fragments in the diagnosis and treatment of Alzheimer’s disease.
