CO-Mediated Relay Catalysis Affords Selective CO2 Hydrogenation to Methanol

Abstract Although technologically promising for producing petrochemicals directly from renewable resources, CO2 hydrogenation to methanol remains a formidable challenge due to the activity-selectivity trade-off. Current industrial copper-based catalysts often generate substantial...

High‐Performance 535‐nm Green Laser Diode Enabling Free‐Space and Underwater Optical Links

ABSTRACT There is a continuous growing demand for visible light communication (VLC) with high‐speed and low‐latency in both free‐space and underwater environments. However, green laser diodes (LDs) remain constrained by the long‐standing “green gap”, where material quality and de...

Toward high-efficiency selective emitters at elevated temperatures with particle doping via synergistic regulation of intrinsic and structural effects

Particle-doped emitters have been investigated in thermophotovoltaic (TPV) systems, where emissivity is controlled by particle composition and volume fraction. However, the impacts of intrinsic optical properties (n, κ) and particle structural parameters on the emission spectrum...

A Thermal-Frequency Locking Method for Permanent Magnet Magnetic Resonance Systems

Abstract Temperature-induced magnetic field drift is a dominant source of slow magnetic field variations in permanent magnet magnetic resonance (PMR) systems, resulting in line broadening, spectral distortion, and imaging artifacts. Conventional methods, such as field-frequency l...

Theoretical framework and thermodynamic performance of a scroll compressor with hybrid profiles for electric vehicle heat pumps

Abstract Heat pumps are critical for enhancing the driving range of electric vehicles. Conventional scroll compressors suffer low efficiency and poor adaptability under extreme conditions, leading to insufficient heating and cooling performance and significant energy consumption....

Organoid‐Driven Open‐Flow Artificial Vessels Inspired by Insect Dorsal Vessel Circulation

ABSTRACT Embedding functional fluid transport into living biohybrid devices remains a critical bottleneck for next‐generation engineered living systems. Conventional strategies rely on external pumps or sealed microfluidic structures, restricting biological compatibility and tiss...

The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites

Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...

Dynamic Supramolecular Helicity in a Multi-Aluminum Porphyrin Catalyst Enables Stereocontrolled Synthesis of Ultrahigh-Molecular-Weight Isotactic Poly(propylene oxide)

Abstract Isotactic poly(propylene oxide) (iPPO) is a robust polyether with photodegradability. However, its stereoselective synthesis from racemic propylene oxide (rac-PO) remains dominated by preconfigured axially chiral cobalt/chromium bimetallic catalysts. Here, we report an i...

Self-Sustaining Ce(IV)/Ce(III) Cycle for Spontaneous Surface Hydroxyl Radical Generation

Abstract Advanced oxidation processes are indispensable for water remediation yet face a fundamental activity–selectivity trade-off, where reactive species are competitively quenched by complex aqueous matrices. While surface-confined chemistry, specifically utilizing surface-ads...

Ultraviolet‐Induced Band Engineering in Black Phosphorus/Gallium Nitride Heterojunction Toward High‐Performance Broadband Photodetection

ABSTRACT Broadband photodetectors that combine ultraviolet sensitivity with visible and near‐infrared response are important for multispectral optoelectronic sensing. However, the performance of these photodetectors is often limited by weak interfacial carrier separation and inef...

Increased receptor binding and spike glycosylation, remodeled immune escape of surging SARS-CoV-2 subvariant BA.3.2.2/RE.2.2/Cicada

SARS-CoV-2 continues to evolve. The subvariant BA.3.2 (Cicada), a derivative of the Omicron BA.3 subtype first detected in late 2024, harbors multiple spike protein mutations, ORF7 and ORF8 deletions, and has recently evolved sublineages (BA.3.2.1 and BA.3.2.2), rendering it a cr...

Deep learning CT signature for predicting early liver metastases in pancreatic ductal adenocarcinoma

Accurately predicting the risk of early liver metastases (ELM) and identifying patients who are most likely to benefit from neoadjuvant therapy (NAT) are critical for pancreatic ductal adenocarcinoma (PDAC). Here, we develop a Mamba-based predictive model that integrates imaging...

Atomic-Scale Intergrowth Regulation Enables Long-Cycling Zero-Strain Sodium Layered Oxide Cathodes

Abstract P2-type layered oxide cathodes feature high median voltage and outstanding cycling stability, but their specific capacity of merely 80 mAh g–1 severely limits practical utility. Conventional P2/O3 biphasic strategies to boost capacity typically sacrifice structural stabi...

Pretrained 3D Molecular Representations Enable Data-Efficient Discovery of High-Energy-Density Fuels

High-energy-density hydrocarbon (HEDH) fuels are essential for aerospace propulsion, yet the design of such fuels is limited by the scarcity of reliable property data. In this work, we fine-tuned Uni-Mol, a pretrained three-dimensional (3D) molecular representation learning frame...

Tuning the Frontier Molecular Orbitals of Aromatic Radicals via Chalcogen Substitution and Heterocyclic Stabilization

Abstract Due to the intrinsic electron-donating effect of chalcogen lone pairs to the aromatic rings, well-characterized radicals, including phenoxy and thiophenoxy, demonstrate that sulfur substitution for oxygen generally raises the electron affinity (EA). Here we report a coun...

An Isolable Terminal Imido Complex of Platinum

Abstract Late transition-metal imido species serve as key intermediates in a variety of catalytic transformations. However, their transient nature renders isolation challenging, and an isolable platinum terminal imido complex has remained elusive to date. In this work, we present...
