All electrical sub-nanosecond field-free switching of perpendicular magnetization with high magnetic field immunity

Spin-orbit torque magnetic random-access memory is a promising next-generation non-volatile memory technology featuring low power consumption, rapid operation, and high endurance. Conventional spin-orbit torque-induced deterministic perpendicular magnetization switching, however,...

Solving Mean-Field Games with Monotonicity Methods in Banach Spaces

Abstract. This paper develops a unified framework for proving the existence of solutions to stationary first-order mean-field games (MFGs) based on the theory of monotone operators in Banach spaces. We cast the coupled MFG system as a variational inequality, overcoming the limita...

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

ABSTRACT Narrow‐bandgap perovskite solar cells (PSCs) are promising absorbers for tandem photovoltaics; however, their performance remains limited by interfacial recombination and instability, particularly Sn 2+ oxidation and halide‐related degradation. Although fullerene derivat...

Beyond PAM: digital photography and RGB color analysis as a cost-effective method for coral bleaching assessment

<title>Abstract</title> Coral reefs are experiencing increased frequency and severity of thermal stress events, underscoring the urgent need for rapid and scalable methods to assess coral bleaching susceptibility. Quantifying bleaching responses typically relies on pulse-amplitud...

Near-Atomic Indium Catalysts Enable Cost-Efficient High-Pressure Reverse Water–Gas Shift

Abstract The reverse water–gas shift (RWGS) reaction is a pivotal step for converting CO2 into value-added chemical intermediates, yet its implementation under industrially relevant high-pressure conditions remains limited by catalyst deactivation, insufficient productivity, and...

Constructing multifunctional biointerfaces: Polyoxometalate-based hydrogels&mdash;design, functionalization, and translational challenges

Abstract Polyoxometalate (POM)-based hydrogels are emerging organic-inorganic hybrid materials that combine the biological functions of POMs with the biocompatibility and tunable mechanical properties of polymer networks. This review summarizes recent advances in their compositio...

Observation of lunge-feeding by pygmy blue whales (Balaenoptera musculus brevicauda) in the Wetar Strait of Timor-Leste

An aerial observation of of pygmy blue whales (Balaenoptera musculus brevicauda) sub-surface feeding in the Wetar Straight of Timor-Leste. Based on current understanding of their foraging ecology, these whales were probably feeding opportunistically on krill-like zooplankton.

Conserving Mass, Momentum, and Energy for the Benjamin–Bona–Mahony, Korteweg–de Vries, and Nonlinear Schrödinger Equations

Abstract. We propose and study a class of arbitrarily high-order numerical discretizations that preserve multiple invariants and are essentially explicit (they do not require the solution of any large systems of algebraic equations). In space, we use Fourier Galerkin methods, whi...

Atomically Precise Rigid Copper Nanocluster as an Air‐Stable Photocatalyst for Three‐Component Coupling Reactions

ABSTRACT Copper‐based catalysts exhibit high versatility in organic synthesis. However, their practical utility is often constrained by the limited stability and sensitivity to reaction conditions. In this study, we report a μ 3 – η 1 –S‐bridged nanocluster (NC), Cu 3 (DPPM) 3 S(...

Integrative taxonomy reveals multiple Mediterranean invasions by Indo-Pacific Dorvillea (Annelida, Dorvilleidae)

Abstract Biological invasions are a major driver of global biodiversity loss, with the Mediterranean Sea among the most heavily invaded marine regions. However, identification and monitoring of Non-Indigenous Species (NIS) are hindered by taxonomic uncertainty and cryptic diversi...

Isolated Cu+–O–Ga3+ Pairs as Structural Motifs that Enhance CO2-to-Methanol Conversion

Abstract Isolated dual-atom sites constitute a promising yet largely unexplored strategy for directing reaction intermediates in CO2 hydrogenation to methanol. In this work, we identify isolated Cu+–O–Ga3+ dual-atom motifs and provide a mechanistically consistent interpretation l...

Room-temperature multiferroicity in all–van der Waals heterostructures

Multiferroics host simultaneous and coupled ferroic orders, allowing disparate external stimuli to induce abrupt transformations in their structures and properties. Creating multiferroicity in two-dimensional (2D) van der Waals (vdW) platforms would add the elements of strong qua...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for t...

A cloud-based Geo-AI framework for automated high-resolution flood mapping with explainable machine learning

Rapid flood mapping is critical for emergency response, but operational workflows often depend on manual training-label generation and have limited multisource integration and interpretability. Here we present a hybrid cloud-local geospatial artificial intelligence (Geo-AI) frame...

Decoding non-faradaic signal transduction in organic electrochemical transistor based biosensors

Organic electrochemical transistors (OECTs) combine amplification and transduction, making them attractive for biochemical sensing. Yet, the fundamental mechanisms by which OECTs convert biochemical binding events into electrical signals remain poorly understood, limiting their o...

Adaptive drop-deployable visible light communication-based underwater sensing probe

Covering under 0.1% of the ocean’s surface, coral reefs support about 30% of all marine life. Nevertheless, this fragile ecosystem is experiencing an extinction threat due to overexploitation and anthropogenically driven pressure. High-frequency and widespread observations are es...

Decentralized GNSS at global scale via graph-aware diffusion adaptation

Abstract Network-based Global Navigation Satellite Systems (GNSS) support critical infrastructure and autonomous systems, but centralized processing hubs limit scalability, resilience, and latency. We present a global-scale decentralized GNSS architecture that jointly estimates r...
