Aqueous zinc-ion batteries(AZIBs) hold great promise as a viable alternative to lithium-ion batteries owing to their high energy density and environmental ***,AZIBs are consistently plagued by the formation of zinc dendrites and concurrent side reactions,which significantly diminish their overall service life,In this study,the glass fiber separator(GF) is modified using zeolite imidazole salt framework-8(ZIF-8),enabling the development of efficient ***-8,which is abundant in nitrogen content,efficiently regulates the desolvation of [Zn(H_(2)O)_(6)]^(2+) to inhibit hydrogen ***,it possesses abundant nanochannels that facilitate the uniform deposition of Zn~(2+) via a localized action,thereby hindering the formation of *** insulating properties of ZIF-8 help prevent Zn^(2+) and water from trapping electron reduction at the layer surface,which reduces corrosion of the zinc ***,ZIF-8-GF achieves the even transport of Zn^(2+) and regulates the homogeneous deposition along the Zn(002) crystal surface,thus significantly enhancing the electrochemical performance of the AZIBs,In particular,the Zn|Zn symmetric cell with the ZIF-8-GF separator delivers a stable cycle life at0.5 mA cm^(-2) of 2300 *** Zn|ZIF-8-GF|MnO_(2) cell exhibits reduced voltage polarization while maintaining a capacity retention rate(93.4%) after 1200 cycles at 1.2 A g^(-1) The unique design of the modified diaphragm provides a new approach to realizing high-performance AZIBs.

Recovery of Flavor Perception and Umami Taste Sensitivity in Young Chinese Adults Following SARS-CoV-2 Omicron Infection: A Case-Control Series

引用

Food Science and Human Wellness 2024年

作者： Yiwen Zhu Xiaoxiao Feng Yuxia Fan Yin Zhang Ye Liu Yuan Liu department of Food Science & technology， School of Agriculture & Biology， Shanghai Jiao Tong University Key Laboratory of Meat processing of Sichuan， Chengdu University Beijing Engineering and technology Research Center of Food Additives， School of Food and Health， Beijing technology and Business University School of Food and Health， Beijing technology and Business University

SARS-CoV-2， particularly the Omicron variant， often leads to flavor perception dysfunction in infected individuals， making a comprehensive understanding of its duration and recovery patterns a critical part of disease management. This study surveyed a cohort of 199 mildly-to-moderately affected SARS-CoV-2 Omicron-infected patients， focusing on the alterations in their olfaction， taste， and chemesthesis perception. Further， a subset of 36 participants (18 healthy and 18 infected) underwent sensory evaluations to check the variation of umami taste sensitivity. The results demonstrated that most of the infected cohort experienced chemosensory disorders， with the recovery period varying between one week and over a month. Intriguingly， the severity of flavor perception changes during infection significantly correlated with the length of the recovery period. Furthermore， this study explored the specific manifestations of flavor perception dysfunction， potential contributing factors， and potential mechanistic explanations for chemosensory disorders. These include local damage， inflammatory responses， and virus-induced neural damage. However， this study revealed no significant change (P > 0.05) in umami taste sensitivity among infected patients 55 days post-infection. While this research faces limitations related to its self-reported， cross-sectional design， and regional focus， it offers valuable insights into the multifaceted impact of COVID-19， particularly the Omicron variant， on chemosensory perception.
