Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures

Advanced Materials, EarlyView.
An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...

Near real-time LOD prediction using ConvLSTM model through integrating IGS rapid LOD and effective angular momentum

Geo-spatial Information Science
Length of day (LOD), a critical component of Earth orientation parameters (EOP), represents variations in Earth’s rotation rate. It is very difficult to predict accurately due to the effects of atmosphere, ocean, hydrology, the Earth’s internal ...

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment

Advanced Materials, EarlyView.
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Collisions and dynamics of particles with magnetic dipole moment and electric charge near magnetized rotating Kerr black holes

European Physical Journal C: Particles and Fields
Analysis of test magnetized and charged particles around black holes immersed in external magnetic fields may help to explain the observed astrophysical phenomena related to black holes, such as the acceleration of particles up to high energies.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

The AMIGA sample of isolated galaxies – effects of environment on angular momentum

Monthly Notices of the Royal Astronomical Society
ABSTRACT We investigate the relationship between the baryonic angular momentum and mass for a sample of 36 isolated disc galaxies with resolved neutral hydrogen (H i) kinematics and infrared Wide-field Infrared Survey Explorer photometry drawn from – and representative in terms of morphologies, stellar masses, and H i-to-star fraction of

Additive Manufacturing of Ni‐Based Thermoelectric Materials for Waste Heat Recovery

Advanced Materials Technologies, EarlyView.
Thermoelectric generators convert waste heat into electricity but are constrained by conventional fabrication. Here, laser powder bed fusion enables direct printing of customised n‐type Cu60Ni40 and p‐type Ni90Cr10 legs. The assembled module achieves 0.8% efficiency at ΔT = 419 K, demonstrating scalable additive manufacturing of eco‐friendly, design ...
