The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.

During the initial impoundment period of a canyon-shaped reservoir, the water body fluctuated violently regarding water level, hydrological condition, and thermal stratification. These variations may alter the structure of phytoplankton community, resulting in algal blooms and seriously threatening the ecological security of the reservoir. It is of great significance to understand the continuous changes of phytoplankton in the initial impoundment period for the protection of reservoir water quality. Therefore, a two-year in -situ monitoring study was conducted on water quality and phytoplankton in a representative canyonshaped reservoir named Sanhekou and the interannual changes of phytoplankton community and its response to environmental changes during the initial impoundment period were discussed at taxonomic versus functional classification levels. The results showed that the total nitrogen and permanganate index levels were relatively high in the first year due to rapid water storage and heavy rainfall input, and the more stable hydrological conditions in the second year promoted the increase of algae density and the transformation of community, and the proportion of cyanobacteria increased significantly. The succession order of phytoplankton in the first year of the initial impoundment period was ChlorophytaBacillariophyta-Chlorophyta, or J/F/X1-P/MP/W1-A/X1/MP, respectively. And the succession order in the second year was Cyanobacteria/Chlorophyta-Bacillariophyta-Chlorophyta, or L M /G/P-P/A/X1-X1/J/G. Water temperature, relative water column stability, mixing depth, and pH were crucial factors affecting phytoplankton community succession. This study revealed the interannual succession law and driving factors of phytoplankton in the initial impound ment period and provided an important reference for the operation management and ecological protection of canyon -shaped reservoirs .

Reactive oxygen species (ROS) are closely related to cell death, proliferation and inflammation. However, excessive ROS levels may exceed the cellular oxidative capacity and cause irreversible damage. Organisms are often inadvertently exposed to nanomaterials (NMs). Therefore, elucidating the specific routes of ROS generation induced by NMs is crucial for comprehending the toxicity mechanisms of NMs and regulating their potential applications. This paper provides a comprehensive review of the toxicity mechanisms and applications of NMs from three perspectives: (1) Organelle perspective. Investigating the impact of NMmediated ROS on mitochondria, unraveling mechanisms at the organelle level. (2) NMs' perspective. Exploring the broad applications and biosafety considerations of Nanozymes, a unique class of NMs. (3) Cellular system. Examining the toxic effects and mechanisms of NMs in cells at a holistic cellular level. Expanding on these perspectives, the paper scrutinizes the regulation of Fenton reactions by NMs in organisms. Furthermore, it introduces diseases resulting from NM-mediated ROS at the organism level. This comprehensive review aims to provide valuable insights for studying NM-mediated mechanisms at both cellular and organism levels, offering considerations for the safe design of nanomaterials.

Motivated by experimental measurements, we investigate the p-Ω correlation functions and interactions on the basis of a quark model. By solving the inverse scattering problem with channel coupling, we renormalize the coupling to other channels into an effective single-channel p-Ω potentials. The effects of Coulomb interaction and spin-averaging are also discussed. According to our results, the depletion of the p-Ω correlation functions, which is attributed to the JP= 2+bound state not observed in the ALICE Collaboration's measurements(Nature 588, 232（2020）), can be explained by the contribution of the attractive JP= 1+component in spin-averaging. So far, we have provided a consistent description of the p-Ω system from the perspective of the quark model, including the energy spectrum, scattering phase shifts, and correlation functions. The existence of the p-Ω bound state has been supported by all three aspects. Additionally, a sign of the p-Ω correlation function's subtle sub-unity part can be seen in experimental measurements, which warrants more precise verification in the future.
