A Li metal-SiO x hybrid anode enabling synergistic plating/alloying dual-mechanism lithium storage

Balancing specific energy and cycle durability remains a critical challenge for practical battery systems, as conventional single-mechanism anodes struggle to optimize both simultaneously. Here, we engineer a symbiotic Li-SiO x hybrid anode enabling spatiotemporally coordinated L...

Functional niche partitioning influences species turnover across supraglacial microbial communities on the Longxiazai glacier, Tibetan Plateau

Glaciers represent unique ecosystems harboring diverse microbial communities that dominate biomass and drive biogeochemical cycling across supraglacial habitats. These microbes transform deposited modern and ancient carbon/nitrogen, and these elements are subsequently transferred...

Graphitization of nitrogen-bearing organic-like carbonaceous material in a dust particle from Chang’e-6 lunar samples

Abstract The delivery and evolution of carbonaceous materials to airless planetary bodies remain poorly constrained. This study characterized a porous, aggregated, carbon-rich dust particle (CE6-CDP) from Chang’e-6 lunar samples. CE6-CDP yielded a mean δ13CVPDB value of − 25.92 ±...

In vivo magnetic recording of neuronal action potentials using a differential TMR magnetrode

Abstract Neuronal magnetic signal recording intrinsically provides vector information and tissue transparency, offering a potential route to overcome the spatial resolution limitations of conventional electrophysiological recordings. However, in situ detection of neuronal magneti...

Stage-specific Cyanobacterial Handoffs and Heterotrophic Subsidies Underpin Biocrust Carbon Accumulation

Abstract Inoculating cyanobacteria is a widely adopted strategy to accelerate biocrust formation and restore dryland soil functions, yet the in situ mechanisms sustaining microbial biomass carbon (MBC) accumulation under seasonal stress remain poorly understood. Here, we combined...

Molecular Design for the Multidimensional Modulation of Supramolecular Nanoparticle Interactions

Abstract Surface ligand engineering based on reversible supramolecular hydrogen bonding provides a versatile strategy for programmable nanoparticle (NP) self-assembly, yet quantitatively linking the molecular structure to interparticle interactions remains challenging. Here, expl...

Postcranial osteology of the giant oviraptorosaur Gigantoraptor erlianensis

Gigantoraptor erlianensis is an unexpectedly large-bodied oviraptorosaurian dinosaur from the Late Cretaceous of Inner Mongolia, China. Exhibiting a bizarre body plan, G. erlianensis is key to revealing the high morphological disparity and complex evolutionary history near the tr...

Lakeshore transformation and water color dynamics: A satellite-based 23-year assessment of nine plateau lakes in Yunnan, China

Study region Nine plateau lakes in Yunnan, China. Study focus We developed an extended lakeshore utilization classification framework to categorize lakeshores as natural, agricultural, or artificial using fixed maximum shorelines. We then derived the Forel–Ule Index (FUI) of the...

Harmonizing A‑Site Cation Incorporation With Conductive Grain‑Boundary Bridging for Durable Perovskite Solar Cells

ABSTRACT While perovskite solar cells (PSCs) have achieved significant progress in power conversion efficiency ( PCE ), their commercialization remains hindered by a critical challenge: irreversible efficiency degradation during device operation, primarily caused by the spontaneo...

Stabilizing Grain Boundaries by Flexible Bidirectional Multisite Hydrazide Cations toward High-Performance Inverted Perovskite Solar Cells

Abstract The grain boundary instability induced by defects and tensible strain impedes the realization of high-performance inverted perovskite solar cells (PSCs). Here, we propose a flexible bidirectional multisite additive strategy to stabilize perovskite. (6-(2,5-Dioxo-2,5-dihy...

How Much Water Can Be Seasonally Buffered by China's Largest Floodplain Lake? A Refined Estimate From SWOT

Abstract Poyang Lake, China's largest floodplain lake, plays a crucial role in regional hydrology by seasonally regulating water to mitigate floods and sustain extensive wetland ecosystems. However, complex hydrodynamics and significant spatial hydraulic gradients often invalidat...

Land Transition Pathways Govern Carbon Storage Dynamics in an Olympic Host Region: A PLUS–InVEST Simulation in Yanqing District

Mega-events can accelerate land–use/land cover change (LULCC) through infrastructure development and ecological interventions, but the carbon consequences of different land transition pathways remain unclear. Using Yanqing District, a host region of the Beijing 2022 Winter Olympi...

Scaling of Urban 3D Form with Emissions and GDP in Chinese Cities

Abstract Rapid urbanization has permanently transformed the face of cities. As the physical manifestation of these transformations, urban form provides a key basis for examining its connections with urban outcomes. While previous studies have primarily focused on two-dimensional...

Crystallization Manipulation Through Buried Pyridinium‐Induced Tunable Interactions in Perovskite Solar Cells

ABSTRACT The interaction between the hybrid component of self‐assembled monolayers (SAMs) and the perovskite precursor could delay the crystallization process, resulting in high‐quality perovskite film and highly efficient perovskite solar cells (PSCs). However, the intensity of...

Tensor-network analysis of root patterns in the XXX model with open boundaries

The string hypothesis of Bethe roots is a cornerstone in the thermodynamic analysis of quantum integrable systems, since it connects root configurations with physical quantities such as the ground-state energy, surface energy and excitation spectra. For integrable models with U(1...

A Comparative Study of Machine-Learning Methods for Early Classification from Sparse Astronomical Light Curves
