Interfacial Coupling Redirects Biaxial Deformation toward Diffusion-Suppressing Phase Reconstruction in Equimass Poly(3-hydroxybutyrate- co -4-hydroxybutyrate)/Poly(lactic acid) Blends

Abstract Combining poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB) with poly(lactic acid) (PLA) offers a biodegradable route to balance deformability, stiffness, and optical clarity, but interfacial instability can compromise structural integrity during biaxial deformation....

Enhanced photocatalytic removal of tetracycline hydrochloride and Cu2+ by the integrated CoFe2O4/g-C3N4 composite and rotating magnetic field system

The widespread occurrence of antibiotics and heavy metals in aquatic environments poses significant risks to ecosystems and human health, yet conventional treatment methods often suffer from incomplete mineralization and limited removal efficiency. An integrated CoFe 2 O 4 /g-C 3...

Rapid Identification of Fritillaria Bulbus Botanical Origins and Adulteration by Thermal‐Assisted Plasma Ionization Time‐of‐Flight Mass Spectrometry Coupled With Chemometrics

ABSTRACT Fritillaria Bulbus (FB) is a valuable traditional Chinese medicine with diverse pharmacological activities. Due to economic incentives, high‐quality FBs are frequently adulterated with morphologically similar counterfeit species in commercial markets. A rapid analytical...

CSPT-SleepNet: An Automatic Sleep Staging Framework Integrating Center-Driven Sequence Supervision and Multimodal Pyramid Token Encoding

Background: Automatic sleep staging is fundamental to sleep architecture analysis and the diagnosis of sleep disorders. Sleep staging requires jointly modeling complementary information across modalities, multi-scale physiological features, and temporal relationships across conse...

Adaptive Influence-Based Borrowing Framework for Improving Treatment Effect Estimation in RCTs Using External Controls

Randomized controlled trials (RCTs) often suffer from limited sample sizes due to high costs and lengthy recruitment periods, compromising precision in treatment effect estimation. External real-world control data offer a valuable opportunity for augmentation, but naïve integrati...

Controlled assembly of MoSe2/N-doped carbon nanoflower spheres via coordination-induced precursor for superior sodium-ion storage

Molybdenum diselenide (MoSe 2 ) suffers from poor conductivity and structural degradation for sodium storage, which hinders its electrochemical performance. Herein, a coordination-induced precursor strategy is proposed to construct three-dimensional MoSe 2 /nitrogen-doped carbon...

Considerable Anisotropy Magnetoresistance by Oxygen-Mediated Spin State Manipulation in a Highly Textured Multilayer for Ultrasensitive Sensor Application

Spin state manipulation in anisotropy magnetoresistance (AMR) materials is key to improving their transport property for constructing highly sensitive and direction-resolvable magnetic sensors. Currently, the mainstream strategy of tuning the transport property focuses on the mod...

Electrochemical Sensor Based on Laser-Induced Graphene for Cortisol Detection in Physiological Media

As a key biomarker for regulating stress levels, timely detection of cortisol can provide an immediate indication of a person’s current stress status and serve as a valuable reference for preventing related diseases. In this study, a laser-induced graphene (LIG)-based electrochem...

Temporal Data Leakage Inflates Machine Learning Performance in Compostable PBAT/PLA Polymer Biodegradation Modeling

Abstract This study quantifies how evaluation protocol choice, not model architecture, governs apparent machine learning (ML) performance in poly(butylene adipate-co-terephthalate)/polylactic acid (PBAT/PLA) composite biodegradation modeling. Seven regression architectures spanni...

Global-Scale Diagnoses of Tropical Cyclone Maximum Wave Heights from 5 Km GPM Retrievals and Their Implications for Reanalysis Bias

Tropical cyclone (TC) inner-core maximum wave height (MWH) measurements are virtually absent, forcing reliance on reanalyses such as ERA5. Using a GPM-retrieved dynamic MWH product on a 5 km pixel grid, 165 global TC–GPM overpass cases of tropical-storm intensity and above, drawn...

Identifying potential biomarkers associated with sebum production, pore enlargement, and comedones using transcriptomic approaches

The molecular mechanisms underlying skin pore issues—excessive sebum secretion, pore enlargement, and comedone formation—remain poorly defined. We collected skin samples from four groups—dry skin without enlarged pores (DNEP), oily skin without enlarged pores (ONEP), oily skin wi...

RiMS-FiLM: Non-Destructive Multimodal Screening for Fixed-Budget Re-Inspection Prioritization of Maize Kernels

Rapid, non-destructive prioritization of maize kernels can help allocate limited re-inspection capacity in post-harvest quality control. Existing deep learning approaches mainly optimize overall classification accuracy and do not explicitly address which samples should be inspect...

One-Pot Ketone Functionalization of EPDM toward Recyclable and Creep-Resistant Elastomers Cross-Linked with Biobased Amines

Abstract Introducing dynamic covalent networks into conventional ethylene-propylene-diene monomer (EPDM) rubber offers a promising strategy for developing thermally reprocessable elastomers; however, it requires the introduction of reactive functionalities onto the chemically ine...

Background Roasting is a crucial refining process for Fenghuang Dancong (FHDC) tea, imparts diverse aroma profiles to the final products. Yashixiang (YS) tea is the most popular FHDC variety among consumers. Methods This study identified the aroma-active compounds (AACs) of YS te...

Lewis Acidic Zn/S-1 Zeolite Enables Direct Dehydrogenative Aromatization of Long-Chain Olefins

Abstract Aromatics, as essential chemical feedstocks, are predominantly derived from nonrenewable petroleum resources. With the rapid advancement of syngas–to–olefins (STO) technology, Fischer–Tropsch (F–T) olefin aromatization has emerged as a promising alternative route for aro...

Fueling service initiative: how AI assimilation shapes employees' proactive service behavior through AI crafting

Purpose Artificial intelligence (AI) is fundamentally reshaping how employees engage in service work. However, few studies have examined how AI assimilation (i.e. the extent to which AI technology is integrated and routinized in work activities and processes) affects employees' p...

Unraveling umami and kokumi: taste characteristics and molecular mechanisms of milk-derived peptides

Although taste-active peptides have been isolated from enzymatic hydrolysates of defatted high-protein milk powder, their sensory properties, processing stability, and receptor-binding mechanisms remain largely unexplored. In this study, we synthesized milk-derived taste- active...

Corporate social responsibility and credit spreads: evidence from family firms in China

This paper examines the relationship between corporate social responsibility (CSR) and the credit spreads of corporate bonds issued by Chinese family firms. Drawing on signaling theory, we argue that CSR serves as a credible signal to reduce information asymmetry, thereby lowerin...
