Formation of a magnetic duct by the compressional component of ULF oscillation: a ray tracing study of whistler-mode wave propagation

open access: yesEarth, Planets and Space
We investigate the propagation of whistler-mode waves in ultralow frequency (ULF) wave-derived magnetic ducts using ray tracing simulations in a two-dimensional dipole coordinate system on the meridian plane. The refractive index modulation caused by the

CRISPR/Cas9‐Assisted Microrobots for Fast and Ultrasensitive “On‐The‐Fly” Next‐Generation DNA Detection

open access: yesAdvanced Functional Materials, EarlyView.
This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

open access: yesAdvanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

A Comparative Study on Ray-Tracing and Physical-Optics Methods for the Analysis of Transmitarray Antennas

open access: yes2025 19th European Conference on Antennas and Propagation (EuCAP)
This study compares the accuracy of two semi-analytical methods based on ray tracing (RT) and physical optics (PO) for the analysis and design of transmitarrays of different sizes. The assessment considers multiple focal-to-diameter ratios and eight unit cells implementing 3-bit uniform phase quantization at 30 GHz.

Tunable Coordination Number in Non‐Metal‐Introduced Copper Catalysts Enables High‐Performance Electrochemical CO2 Reduction to C2 Products

open access: yesAdvanced Functional Materials, EarlyView.
Copper catalysts introduced with different non‐metallic elements regulating the coordination number of Cu are prepared by magnetron sputtering. Reducing the Cu coordination number enhances C─C coupling and boosts C2+ product selectivity, by lowering the energy barrier for the *CO → *CHO conversion step. The optimized Si‐doped Cu catalyst achieves a C2+

Tracing the Physical Lineage of GRB 211211A: Population Constraints on NS–WD Merger Gamma-Ray Bursts

open access: yesThe Astrophysical Journal
Abstract The peculiar long gamma-ray burst (GRB) event, GRB 211211A, is known for its association with a kilonova feature. Whereas most long GRBs are thought to originate in the core collapse of massive stars, the presence of a kilonova suggests GRB 211211A was instead produced by a merger of a compact object ...

Defect‐Mediated Scintillation in Fully Inorganic Perovskites via Water‐Induced 0D/3D Phase Modulation

open access: yesAdvanced Functional Materials, EarlyView.
A reproducible synthesis to control 3D/0D phase ratios via water‐tuned solvent–antisolvent methods is presented. Enhanced scintillation yield and ultrafast decay are achieved. Defect‐driven emission mechanisms are revealed through cathodoluminescence and radioluminescence, shedding light on the underexplored role of the 0D Cs4PbBr6 and mixed 0D/3D ...

IntrinsicAvatar: Physically Based Inverse Rendering of Dynamic Humans from Monocular Videos via Explicit Ray Tracing

open access: yes2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
We present IntrinsicAvatar, a novel approach to recovering the intrinsic properties of clothed human avatars including geometry, albedo, material, and environment lighting from only monocular videos. Recent advancements in human-based neural rendering have enabled high-quality geometry and appearance reconstruction of clothed humans from just monocular
