Deuterated Aprotic Electrolytes Enable Rechargeable Lithium Batteries With High (Electro)Chemical and Thermal Stability

ABSTRACT Electrolytes with exceptional (electro)chemical and thermal stability are essential prerequisites for high‐energy‐density rechargeable lithium batteries. Conventional aprotic ether and ester solvents contain polarizable C─H bonds that trigger parasitic proton transfer re...

Modular flow of celestial conformal field theory

Abstract We first review the calculations for the modular flow and the vector flow of $$\text {CFT}_2$$ CFT 2 , warped CFTs and Bondi–Metzner–Sachs field theories (BMSFTs), and then we present the vector flows and modular flows in Celestial field theory and Klein CFTs. We also di...

A Subtle Atmospheric Shift Is Redefining Winter Hydrology on the Tibetan Plateau

Abstract Winter climate over the Tibetan Plateau has long been characterized by cold conditions that preserve snow and regulate downstream water supply through delayed melt. Here we show that this buffering function is weakening in the Sanjiangyuan region due to a shift in winter...

Gut microbiome seasonality is associated with dietary plasticity and coexistence in three sympatric Pamir ungulates

This graphical abstract outlines a multi-omics framework investigating the seasonal dietary composition and gut microbial communities of three coexisting ungulate species inhabiting the extreme high-altitude Pamir Plateau (Ovis ammon polii, Capra sibirica, and Pseudois nayaur). B...

Beyond the factor-driven paradigm: Spatiotemporal dynamics and system coupling of agricultural transition in Henan Province, China

The core of agricultural transition lies in changes to the various components of the agricultural systems and their interactions. Drawing on the social-ecological-technological systems (SETS) framework, this study developed an “element coupling–external manifestation” analytical...

An Optically Transparent Metamaterial Window Based on Metal Meshes With Integrated Absorption and Transmission

ABSTRACT This work presents an absorptive–transmissive integrated metamaterial window using a quartz substrate and micrometer‐scale metallic meshes. The structure employs a three‐layer design comprising a resonant layer, a dielectric spacer, and a frequency‐selective surface. It...

Selective Hydrogenation of α,β‐Unsaturated aldehydes to Unsaturated alcohols: From Metal Nanoparticles to Nanoclusters and Single‐Atom Catalysts

The selective hydrogenation of α,β‐unsaturated aldehydes is a pivotal process for synthesizing fine chemicals, fragrances, and pharmaceuticals. However, achieving high chemoselectivity to unsaturated alcohols remains a significant challenge due to the thermodynamic and kinetic pr...

Ga Doping Enables (110) Facet Control and Surface Passivation of SnO 2 for Efficient and Stable Inverted Perovskite Solar Cells

ABSTRACT Perovskite solar cells (pero‐SCs) with inverted ( p–i–n ) architecture have advanced rapidly, yet combining high efficiency with long‐term operational stability remains challenging, mainly due to commonly used organic cathode buffer layer (CBL) (between C 60 electron tra...

Machine learning-enhanced 4DVar assimilation for winter wheat yield estimation

Context Accurate crop yield estimation is crucial for ensuring food security, promoting sustainable agriculture, and optimizing management practices. However, integrating remote sensing data with crop models remains challenging, largely due to the inability of traditional data as...

Pixel‐Level Reconfigurable Pancharatnam–Berry Phase Induced by Inter‐Layer Coupling of Isotropic Metasurfaces

ABSTRACT The growing demand for dynamic electromagnetic wave control has accelerated the development of programmable metasurfaces. However, conventional approaches that rely on active components such as pin diodes, varactor diodes, and liquid crystals often suffer from limited mo...

Experimental study of the startup and heat-transfer performance of a novel two-phase closed thermosyphon with an internal phase-separation structure

Two-phase closed thermosyphons (TPCTs) are widely used as active cooling devices in permafrost engineering. Countercurrent transport of rising gas and returning liquid through a shared flow channel can impede working-medium circulation and constrain heat-transfer performance. Thi...

Heatwave‐Period Temperature Response Parameterizations Amplify Modeled Isoprene Emissions From Temperate Trees

Abstract Heatwaves can alter temperature responses of biogenic volatile organic compound emissions, yet these effects remain poorly constrained for temperate trees. We measured leaf‐level isoprene temperature response curves for Platanus occidentalis and Populus deltoides in cent...

Astronomical spectra as language: Order-agnostic foundation model for low-SNR reconstruction and stellar parameter prediction

Large-scale spectroscopic surveys contain numerous low-SNR stellar spectra that are difficult to analyze with traditional pipelines but remain valuable for Galactic archaeology, chemical-evolution studies, and population-level stellar characterization. We propose an order-agnosti...
