Phase‐Controlled Bi 2 O 3 Nanosheets for Highly Efficient Electrochemical CO 2 Reduction to Formate

ABSTRACT The electrochemical carbon dioxide reduction reaction (CO 2 RR) offers a sustainable route to convert CO 2 into valuable chemicals, with formic acid being one of the most economically attractive products. Bismuth (Bi)‐based materials have shown promise as CO 2 RR electro...

Language-enhanced generative modeling for amyloid PET synthesis from MRI and blood biomarkers.

Assessment of amyloid pathology in Alzheimer's disease (AD) often relies on amyloid-beta positron emission tomography (Aβ-PET), but its clinical use is limited by cost and accessibility. We developed a language-enhanced generative framework to synthesize Aβ-PET images from T1-wei...

Electron transfer kinetics and molecular structural basis of dissolved black carbon as an electron shuttle

Dissolved black carbon (DBC) serves as a crucial electron shuttle in various biogeochemical cycles owing to its highly mobile and redox-active nature. Prior work on DBC electron-shuttling has focused on thermodynamic metrics—electron donating capacity (EDC) and electron accepting...

stDSVA: spatial transcriptomics deconvolution with a semi-supervised framework and cell type variation analysis

Spatial transcriptomics (ST) integrates transcriptomic profiling with tissue architecture, enabling the investigation of spatial heterogeneity in gene expression within intact tissues. However, due to the limited resolution of many current ST platforms, computational deconvolutio...

Improving Quantum-ChemicalPrediction of 19F NMR Chemical Shifts via Machine Learning

Abstract 19F nuclear magnetic resonance (NMR) spectroscopy is widely used for structural elucidation of fluorinated molecules, but reliable prediction of 19F chemical shifts remains challenging because quantum-chemical calculations are computationally demanding and their accuracy...

Bridging the GapBetween Laboratory Catalyst Researchand Practical Water Electrolyzer Commercialization

Abstract Water electrolyzers are key technologies for enabling a carbon-neutral society by facilitating sustainable hydrogen production. Despite extensive efforts to develop highly active catalysts, a persistent gap remains between catalyst performance evaluated in rotating disk...

Persistent Shelf‐to‐Basin Export of Bioavailable Dissolved Organic Carbon in the Arctic Ocean

Abstract Microbial carbon demand often exceeds local primary production in the oligotrophic central Arctic Ocean. Whether shelf‐derived dissolved organic carbon (DOC) provides a persistent carbon subsidy to reconcile this imbalance remains unclear. Here, we combine amino acid‐bas...

Occupational identity, competence dimensions, and psychological well-being among Chinese public security personnel: a cross-sectional path analysis

Police personnel are exposed to substantial occupational stress, yet less is known about how occupational identity and different dimensions of occupational competence are associated with psychological well-being. This study examined the direct associations of occupational cogniti...

STELT: A spatiotemporal deep learning framework for diffusion-ordered NMR spectroscopy reconstruction with artifact suppression

Diffusion Ordered NMR Spectroscopy (DOSY) is a powerful technique for studying mixtures by probing the diffusion behavior of mixed compounds and enabling their identification and separation in mixture samples. The performance of DOSY generally relies on the adopted reconstruction...

Aero-DETR: a frequency-adaptive sparse-interaction network for UAV-assisted aircraft surface defect detection

Abstract Aircraft surface defect inspection is critical for aviation safety but remains challenging because defects in unmanned aerial vehicle (UAV) imagery are often small, low-contrast, and multi-scale. We construct the aircraft UAV defect inspection dataset (AUDID), containing...

Sensitive andReproducible SERS Profiling of Tumor-DerivedEVs via Uniform Microfluidic Nanobowl Arrays for Pancreatic CancerManagement

Abstract Tumor-derived extracellular vesicles (EVs) are promising liquid biopsy biomarkers, yet their clinical translation is hindered by the trade-off between enhancement and reproducibility of SERS-based detection. Here, we present a microfluidic SERS platform integrating plasm...

Separation and recovery of Ni 2+ by foam separation using soapberry extract

Abstract BACKGROUND Foam separation is a low‐energy method for recovering dilute metal ions, but its practical use is often limited by reliance on synthetic surfactants. This study evaluated soapberry extract (SE), a biodegradable natural surfactant, for the separation and recove...

Drivers of CO 2 Reduction in OECD : Financial Structure and FDI via MMQR

ABSTRACT The study analyzes the response of disaggregated level foreign direct investment (FDI) and financial structure on the CO 2 intensity of 30 high energy‐consuming OECD countries. To this end, the study applies the Method of Moment Quantile Regression (MMQR) to the data bet...

Tailoring MicrophaseSeparation through Backbone SubstituentModulation in Poly(biphenyl alkylene) Anion Exchange Membranes

Abstract Anion exchange membrane (AEM) water electrolysis serves as an attractive approach for cost-effective hydrogen generation. However, achieving AEMs with both high ionic conductivity and robust alkaline stability remains challenging. Herein, a series of ether-free quaterniz...

Endothelial cell-microglia crosstalk mediates heart failure-associated synaptic loss and cognitive impairment in male mice

Cognitive impairment affects 30%–80% of patients with heart failure, yet the mechanisms beyond reduced brain blood flow remain poorly defined. Here we show that circulating factors released during heart failure trigger senescence of brain blood-vessel endothelial cells, which in...
