Co9S8 has attracted much attention as a potential alternative to graphite anode material for lithium-ion batteries (LIBs). Hollow core–shell structured microspheres of Co9S8 nanosheets@mesoporous carbon with Co9S8 nanosheets embedded in mesoporous carbon hollow spheres (abbr. Co9S8 HCSM) were successfully fabricated through a facile process, which includes two parts: (1) the hydrothermal synthesis of Co9S8 nanosheets; and (2) the construction of mesoporous carbon shell by a sol–gel process. The as-prepared samples were characterized by XRD, XPS, SEM, TEM, and N2 adsorption techniques, respectively. Their electrochemical performance, based on the Co9S8 HCSM as an anode material, was also investigated. Results showed that Co9S8 HCSM composites had a unique core–shell structure, which not only promoted electrolyte penetration and electron/ion transfer to improve the electrochemical performance of LIBs, but also prevented the aggregation of Co9S8 nanosheets and alleviated mechanical strains during the charge/discharge process, enhancing their cycling stability. The Co9S8 HCSM composites exhibited excellent electrochemical performance, such as a relatively high discharge specific capacity (1144.4 mAh g−1 at a current density of 0.1 A g−1 after 45 cycles), and long-term cycle stability at a high rate (502.6 mAh g−1 for 900 cycles at 2.0 A g−1). The present study provides a new idea for developing low-cost and high-performance anode materials for LIBs. [ABSTRACT FROM AUTHOR]

Dynamic changes in protein glycosylation impact human health and disease progression. However, current resources that capture disease and phenotype information focus primarily on the macromolecules within the central dogma of molecular biology (DNA, RNA, proteins). To gain a better understanding of organisms, there is a need to capture the functional impact of glycans and glycosylation on biological processes. A workshop titled "Functional impact of glycans and their curation" was held in conjunction with the 16th Annual International Biocuration Conference to discuss ongoing worldwide activities related to glycan function curation. This workshop brought together subject matter experts, tool developers, and biocurators from over 20 projects and bioinformatics resources. Participants discussed four key topics for each of their resources: (i) how they curate glycan function-related data from publications and other sources, (ii) what type of data they would like to acquire, (iii) what data they currently have, and (iv) what standards they use. Their answers contributed input that provided a comprehensive overview of state-of-the-art glycan function curation and annotations. This report summarizes the outcome of discussions, including potential solutions and areas where curators, data wranglers, and text mining experts can collaborate to address current gaps in glycan and glycosylation annotations, leveraging each other's work to improve their respective resources and encourage impactful data sharing among resources.
