  摘要：The underlying reaction mechanism in lithium-ion batteries remains poorly understood. We provide experimental and theoretical evidence that lithium intercalation occurs by coupled ion-electron transfer, where ion transfer across the electrode-electrolyte interface is facilitated by electron transfer to a neighboring redox site. Electrochemical measurements for a variety of common electrode and electrolyte materials reveal a universal dependence of the (de-)intercalation rate on Li+ vacancy fra...

  摘要：We used a retrained machine learning workflow to enhance the performance of the seismic monitoring network at Campi Flegrei caldera (CFc) for improved tracking of the evolution of volcanic unrest. We analyzed the recent (21 January 2022 to 20 March 2025) continuous seismic data, which showed a sharp increase in seismicity at the highly populated CFc. Our analysis expanded the seismicity catalog from around 12,000 to more than 54,000 earthquakes. The more complete picture of seismicity revealed...

  摘要：Diboron trioxide (B2O3) represents an unusual case among polymorphic oxides, because its vitrified state features superstructural units-planar boroxol groups-that are never observed in its three-dimensional crystalline polymorphs. Crystalline polymorphs that incorporate boroxol groups have only been predicted theoretically, although their formation is crucial to rationalize the ability of B2O3 to vitrify. Here we present the synthesis of a two-dimensional crystalline B2O3 polymorph constituted...

  摘要：Adenosine triphosphate (ATP)-dependent chromatin remodeling enzymes mobilize nucleosomes, but how such mobilization affects chromatin condensation is unclear. We investigate effects of two major remodelers, ACF and RSC, using chromatin condensates and single-molecule footprinting. We find that both remodelers inhibit the formation of condensed chromatin. However, the remodelers have distinct effects on preformed chromatin condensates. ACF spaces nucleosomes without decondensing the chromatin, ...

  摘要：Plant roots release exudates to encourage microbiome assembly, which influences the function and stress resilience of plants. How specific exudates drive spatial colonization patterns remains largely unknown. In this study, we demonstrate that endodermal Casparian strips-forming the root's extracellular diffusion barrier-restrict nutrient leakage into the rhizosphere, coinciding with and controlling spatial colonization patterns of rhizobacteria. We find that vasculature-derived glutamine leak...

  摘要：Paleogenomic studies suggest that Mammuthus columbi derives from an ancient hybridization between Mammuthus primigenius and Mammuthus trogontherii. Although its habitat spanned from North to Central America, available genetic data are limited to temperate regions, leaving gaps in knowledge of the species' demographic history on the continent. In this study, we generated 61 capture-enriched M. columbi mitogenomes from the Basin of Mexico, located in Central Mexico. Our analysis reveals that the...
