Simultaneous acceleration of sulfur reduction and oxidation on bifunctional electrocatalytic electrodes for quasi-solid-state Zn–S batteries

The incomplete sulfur reduction and high ZnS re-oxidation energy barrier along with severe side reactions during the battery cycling compromise the practical application of Zn–S electrochemistry. Herein, a bifunctional electrocatalytic sulfur matrix that simultaneously accelerates the sulfur reduction and ZnS oxidation is proposed to realize a highly-efficient Zn–S cell. It is revealed that the N-heteroatom hotspots are more favorable for facilitating the conversion of S to ZnS while the CoO nanocrystal substantially lowers the ZnS activation energy barrier thereby suppressing the formation of disproportionation species(e.g.,SO_(4)^(2-)) and accumulation of inactive ZnS. Accordingly, the Co O anchored on the N-doped carbon-supported sulfur cathode delivers a high Zn^(2+)storage capacity of 1,172 m Ahg^(-1)and outstanding cycling stability with a capacity retention of 71.6% after500 cycles with a high average Coulombic efficiency of 97.8%. Simultaneously, the stable cycling of solid-state Zn–S pouch cells with an energy density of 585 Whkg^(-1)sulfuris also demonstrated. Moreover, the postmortem analysis reveals that the degradation of Zn–S cells is mainly attributed to the limited reversibility of Zn anodes rather than the ZnS decomposition and/or accumulation. The approach to the bidirectional catalysis manipulated the sulfur redox provides a new perspective to realize the theoretical potentials of Zn–S cells.

Comparison of Lumbopelvic-Hip Rotation Asymmetry and Pelvic Asymmetry between Individuals with and without Nonspecific Low Back Pain

引用

Journal of Biosciences and Medicines 2024年第9期12卷 314-328页

作者： Qianhui Sun Heng-Ju Lee Cheng-Feng Lin Rakhmad Rosadi Department of physical education and Sport Sciences National Taiwan Normal University Taipei City Department of physical Therapy National Cheng Kung University Tainan Department of Physiotherapy Faculty of Health Science University of Muhammadiyah Malang Malang Indonesia

Background: low back pain affects many individuals, with 80% classified as non-specific low back pain (NSLBP) due to mechanical rather than structural issues. The link between pelvic alignment and lumbopelvic-hip rotation movement for NSLBP is controversial. Methods: twenty males with NSLBP and 20 healthy males participated. Data collected included static pelvic asymmetry and active lumbopelvic-hip rotation with motion capture system for kinematic analysis. Results: Unpaired T test was used to compare the difference of kinematic parameters between two groups. NSLBP group showed significantly larger angles between the ASIS-PSIS line and the z-axis (p Conclusion: Evaluations focusing on bone structure alone may be inadequate. A more comprehensive approach including functional assessments like muscle strength and range of motion could be beneficial. Integrating lumbopelvic-hip movement patterns and pelvic symmetry into clinical assessments should be considered, as they may be influenced by physical activity.

Excitonic devices based on two-dimensional transition metal dichalcogenides van der Waals heterostructures

Frontiers of Chemical Science and Engineering 2024年第2期18卷 41-67页

作者： Yulun Liu Yaojie Zhu Zuowei Yan Ruixue Bai Xilin Zhang Yanbo Ren Xiaoyu Cheng Hui Ma Chongyun Jiang College of Electronic Information and Optical Engineering Nankai UniversityTianjin 300350China School of physical Science and Technology Tiangong UniversityTianjin 300387China

Excitonic devices are an emerging class of technology that utilizes excitons as carriers for encoding, transmitting, and storing information. Van der Waals heterostructures based on transition metal dichalcogenides often exhibit a type II band alignment, which facilitates the generation of interlayer excitons. As a bonded pair of electrons and holes in the separation layer, interlayer excitons offer the chance to investigate exciton transport due to their intrinsic out-of-plane dipole moment and extended exciton lifetime. Furthermore, interlayer excitons can potentially analyze other encoding strategies for information processing beyond the conventional utilization of spin and charge. The review provided valuable insights and recommendations for researchers studying interlayer excitonic devices within van der Waals heterostructures based on transition metal dichalcogenides. Firstly, we provide an overview of the essential attributes of transition metal dichalcogenide materials, focusing on their fundamental properties, excitonic effects, and the distinctive features exhibited by interlayer excitons in van der Waals heterostructures. Subsequently, this discourse emphasizes the recent advancements in interlayer excitonic devices founded on van der Waals heterostructures, with specific attention is given to the utilization of valley electronics for information processing, employing the valley index. In conclusion, this paper examines the potential and current challenges associated with excitonic devices.
