Dopant-Level Cobalt as an Electronic Promoter Stabilizes NiOOH for the Efficient Electrochemical Oxidation of 5-Hydroxymethylfurfural (HMF) to 2,5-Furandicarboxylic Acid (FDCA)

Abstract The electrochemical oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a promising route to biobased polymers using Ni-based hydroxide anodes. Although Co incorporation enhances performance, its mechanistic role in HMF oxidation remains un...

Geometry-engineered heat sinks for enhanced cooling performance in immersion-cooled servers

This study introduces a novel geometry-engineered dual-CPU heat sink framework for single-phase immersion liquid cooling (SPILC) servers, addressing the limitations of uniform designs that ignore the distinct thermal-hydraulic conditions of upstream and downstream CPUs. The origi...

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

ABSTRACT Dark current density ( J D ) fundamentally limits the noise characteristics and detectivity of organic photodetectors (OPDs), arising primarily from reverse‐bias carrier injection and trap‐mediated leakage pathways in donor‐acceptor (D‐A) bulk‐heterojunction (BHJ) active...

Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

ABSTRACT Phosphoric acid (PA)‐related challenges, including PA loss, redistribution, and flooding, critically limit the performance and long‐term durability of high‐temperature proton exchange membrane fuel cells (HT‐PEMFCs) based on PA‐doped membrane electrode assemblies. Althou...

Three-Year Outcomes of Drug-Eluting Stents, Drug-Coated Balloons, and Non-Drug-Eluting Devices in Native Femoropopliteal Artery Disease: An Analysis of the K-VIS ELLA Registry

Background: Although drug-eluting devices have demonstrated improved efficacy in femoropopliteal artery (FPA) disease, evidence on their long-term clinical outcomes in realworld practice remains limited.Methods: Using data from the multicenter Korean Vascular Intervention Society...

Drug Survival of Omalizumab and Factors Associated With Discontinuation in Chronic Urticaria

Importance Omalizumab is a recommended second-line therapy for chronic urticaria (CU), yet clinical evidence regarding long-term drug survival and determinants of discontinuation remains limited. Understanding drug survival patterns may inform clinical decision-making and patient...

Predicting clinical dementia rating scores from neuropsychological testing: a machine learning study in a large clinical cohort

To reduce variability of Clinical Dementia Rating (CDR) assessments taken from raters and informants, quantitative and reproducible approaches to support consistent interpretation are needed. We developed multiclass classification models of CDR global and regression models of CDR...

Differential Diagnosis of Lung Cancer Using Artificial Intelligence-Based Extracellular Vesicle Analysis: A Pilot Study

Abstract In cancer diagnosis, liquid biopsy is a minimally invasive method, yet its diagnostic performance is constrained by insufficient sensitivity and restricted blood biomarkers. Therefore, the use of additional invasive methods is unavoidable to identify cancer-specific info...

Genetic mutations driving ciprofloxacin resistance in laboratory-evolved Salmonella Typhimurium

ABSTRACT Ciprofloxacin resistance in Salmonella Typhimurium is a significant public health concern, and the mechanisms by which the resistance evolves are poorly defined. Here, by serial passaging under antibiotic selection, we isolated ciprofloxacin-resistant S . Typhimurium mut...

Predicting the status of 35 sustainable development goal indicators in Indian villages: a semi-supervised machine learning approach for precision public policy

Background National and district-level monitoring of the Sustainable Development Goals (SDGs) in India obscures substantial inequalities at finer geographic resolutions, such as villages. While villages are central to service delivery and local governance, village-level estimates...

Anion‐Transferring Electrolyte Enables In Situ Construction of Uniform LiF‐Rich Interphases for Long‐Cycling Lithium–Sulfur Batteries

ABSTRACT Stabilizing electrode/electrolyte interphases is crucial for high‐performance lithium–sulfur batteries; however, simultaneously fabricating robust interphases on both the lithium anode and sulfur cathode is challenging. Here, we report an anion‐transferring functional el...
