Coherent terahertz magnon–phonon three-wave mixing in a layered antiferromagnet

The coherent nonlinear dynamics between collective excitations, such as magnons and phonons, drive emergent phenomena in quantum materials, yet their direct observation remains limited. Here, using double-terahertz-pump optical-probe spectroscopy, we report the direct observation...

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...

Rotational accuracy of an aerostatic motorized spindle under gas–magnetic field coupling

Assembly eccentricities of the stator and rotor disturb the motor air-gap distribution and induce unbalanced magnetic pull (UMP), which subsequently affects the rotational accuracy of aerostatic motorized spindles. To clarify the underlying mechanism, this study establishes a gas...

Ultrahigh-sensitivity adaptive solar-blind organic neuromorphic sensors for robust corona discharge monitoring

Abstract Low‑cost and high‑efficiency corona-discharge detection is essential for safe high‑voltage transmission operation, yet state‑of‑the‑art solar‑blind ultraviolet (SBUV) photodetectors for corona monitoring suffer from insufficient sensitivity, poor stability and weak anti‑...

Features of Regional Compound Dry‐Hot Events Over the Yangtze River Basin in Warm Season and Related Mechanisms

Abstract Based on daily station observations and ERA5 reanalysis data during warm seasons of 1961–2024, the characteristics of regional compound dry‐hot events (RCDHEs) and associated mechanisms over Yangtze River Basin (YRB) have been systematically explored. Results show more t...

Supramolecular immunomodulatory hydrogelator potentiates CAR-T therapy with long-lasting endogenous immunity toward solid tumor eradication

The success of chimeric antigen receptor (CAR)-T cell therapy in hematologic malignancies has not been translated to solid tumors, primarily due to inadequate T cell infiltration and an immunosuppressive tumor microenvironment that drives T cell exhaustion. To address these chall...

Design of a Pop-Up Divertor Langmuir Probe System for the HL-3 Tokamak

A novel pop-up divertor Langmuir probe system is developed for measuring the plasma parameters on divertor target plates in HL-3 tokamak. The system enables reliable ejection and retraction in strong magnetic-field environments and adopts a modular design consisting of a probe as...

Integration of Multi-Omics Reveals Genomic Features of Chromatin Accessibility in Gardenia jasminoides J.Ellis Leaves

Chromatin accessibility is an important feature of cis-regulatory elements that shapes gene regulation in plants; however, it has been studied less frequently in traditional medicinal plants such as Gardenia jasminoides J.Ellis (G. jasminoides). This study applied Assay for Trans...

Robust 4f-2p-3d electron ladder for boosting the stability of oxygen electrocatalysis

Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are recognized as the core bifunctional catalytic processes in metal-air batteries, yet their inferior stability severely limits the large-scale deployment of these frontier devices. For resolving it, a bifunctio...

Analytical Study for Transient Infiltration of Water in Vegetated Landfill Cover under a Time-Varying Rainfall Scenario

Abstract Vegetated landfill covers (VLC) are extensively applied to block rainwater infiltration and reduce the leachate generation. However, the associated analytical works remain limited. This study, for the first time to our best knowledge, develops analytical solutions for tr...

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...

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...

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...

Assessing Land Cover Change and Forest Sustainability in a World Heritage Context: Evidence from the Okapi Wildlife Reserve

Long-term monitoring of land cover dynamics is essential for evaluating conservation outcomes in World Heritage sites, yet remains challenging in conflict-affected regions with limited field observations. This study aims to reconstruct annual land cover dynamics and assess forest...

Noncollinear kagome magnet driven by giant antisymmetric exchange

Kagome lattices host exotic phenomena such as quantum spin liquids, topological Weyl nodes, and flat bands. The kagome ferromagnet Co3Sn2S2 has been a focus of debate due to conflicting reports on its magnetic character. Here, using weakly perturbative probes—primarily neutron sc...

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...
