With the proposal of "peak carbon dioxide emissions" and "carbon neutral" strategic objectives, developing clean energy and promoting the development of new energy industry has become the consensus of the whole society. Lithium battery as the candidate for new generation of energy storage equipment due to its remarkable advantages such as high energy density, high power density, long cycle life and environmental friendliness. Its development plays a significant role in alleviating energy crisis, driving the conversion of old kinetic energy into new and achieving the strategic goal of "carbon peaking and carbon neutrality". In order to further improve the energy density of lithium batteries, the most effective strategy is to use high voltage or high specific capacity cathode materials. However, due to the low oxidation stability and narrow electrochemical window of traditional carbonate ester electrolytes, they are prone to oxidative decomposition when the working voltage exceeds 4.2 V, which cannot be cycled stably at high voltages, so it is particularly important to broaden the electrochemical window of electrolytes. This paper mainly discusses the mechanism of organic solvents and additives in high-voltage electrolytes, explores effective methods to broaden the electrochemical window of new electrolytes, summarizes the characteristics of aqueous electrolytes, solid electrolytes, and polymer gel electrolytes, and finally; summarizes and outlooks the future development and prospects of high-voltage electrolytes to provide scientific basis for the design and development of high-voltage electrolytes for lithium batteries.

Polyurethane, a prevalent polymer, has garnered considerable attention owing to its exceptional overall performance within various applications. However, even minor damages can significantly curtail the service life of polyurethane. Consequently, a promising approach to address this challenge involves conferring self-healing properties upon polyurethane. Among the various healing mechanisms found in self-healing polyurethane, the intrinsic driving force stands out as the most common. This mechanism entails the spontaneous re-entanglement of polyurethane molecular chains through meticulous molecular structure design, obviating the necessity for external healing agents. Intrinsic driving force encompasses reversible covalent bonds (e.g., disulfide bonds, Diels-Alder reactions, and boronic ester bonds) as well as dynamic non-covalent interactions (e.g., hydrogen bonds, ionic bonds, metal coordination bonds, and host-guest interactions). The polyurethane main chain can possess a single intrinsic driving force or multiple intrinsic driving forces concurrently. Nevertheless, while self-healing polyurethane alone presents advantages in terms of extending service life and reducing maintenance costs through damage repair, it still falls short of meeting the usage requirements in certain specialized applications. To further enable the versatile application of self-healing polyurethane while preserving its self-healing properties, the incorporation of new functional groups becomes an enticing prospect. These functional groups can bestow specific properties upon polyurethane, such as shape memory, degradability, antibacterial properties and biocompatibility, thereby achieving functional integration within self-healing polyurethane. Importantly, these functionalized self-healing polyurethanes possess the potential to supplant traditional materials as dielectric materials, substrate materials, or encapsulation materials in the realm of flexible sensors. Consequently, they contribute to enhancing the reliability and durability of flexible sensors. Therefore, this article primarily focuses on elucidating the self-healing mechanism of self-healing polyurethane. Subsequently, it delves into the integration of functionality within self-healing polyurethane and its application within the field of flexible sensors. Lastly, based on these insights, the paper provides a glimpse into the future prospects for the development of self-healing polyurethane.

Metal-organic frameworks (MOFs) are a new generation of crystalline porous materials with void space structures constructed from metal ions or clusters and organic ligands through coordination bonds, and have been a hot research topic in the field of coordination chemistry over the past two decades. As the novel multifunctional materials, MOFs have been widely used in various fields due to their high porosities, low densities, large surface areas, tunable pore sizes, diverse topological structures and tailorabilities. Although MOFs have many advantages, most of MOFs materials have relatively lower water and chemical stability and cannot maintain their structures under harsh conditions, which greatly restrict their practical applications under moisture-rich conditions. Therefore, chemically stable MOFs materials will have greater application prospects. In recent years, researchers have carried out a lot of exploration in improving the chemical stability of MOFs, and developed some excellent methods to synthesize chemically stable MOFs. This review will mainly focus on the latest research progress in the syntheses of chemically stable MOFs during the past five years.

Finally, the importance of TCM-CDs research, the main problems and challenges in this fields and the future development direction are summarized and outlooked.

Prussian blue (PB) and its analogues (PBAs), which are composed of three-dimensional frame structure, are ideal cathode materials for sodium ion battery (SIB) and can provide a wide channel for sodium ion embedding and removal. However, there are a lot of water molecules and vacancies in PBAs materials, which greatly reduces the storage sites of sodium ions. Furthermore, transition metal ions in the metal organic framework are easy to dissolve during the cycles, resulting in limited sodium storage capacity and poor cycle stability of PBAs cathode materials.

Due to the excellent optical properties, good biocompatibility, high reactive oxygen species yield and excellent photothermal conversion ability, aggregation-induced emission (AIE) materials show great potential applications in the fields of photodynamic and photothermal therapy. However, traditional fluorescent materials need light with short wavelength for emission, which has the problem of poor tissue penetration, and further restricts the clinical application.

Tumor has been one of the most common causes of death worldwide, while chemotherapy is still the major tool for antitumor treatment. As a broad-spectrum anthracycline-type antitumor drug, doxorubicin (DOX) has been widely used in different types of tumors in clinical practices.
