Quinoline-Based Amide Foldamers with One-Handed Chirality Induced by an Asymmetric Plane

Abstract A quinoline-containing cyclophane derivative with planar chirality was rationally designed and synthesized based on [2.2]paracyclophane (PCP) and used as a structural unit to induce the absolute one-handed helical conformation of quinoline foldamers. 1H NMR, X-ray crysta...

Constitutive Model and High Temperature Rheological Behavior of PEEK

Accurately characterizing the mechanical behavior of polyether ether ketone (PEEK) under low strain rate conditions and over a wide temperature range is essential for predicting the mechanical performance of PEEK and PEEK-based composites. In this study, PEEK grade ZYPEEK®-330G w...

Radical Passivation to Incubate Closed Pore Structure and Surface Functionalities of Hard Carbon for High‐Efficiency Sodium Storage

ABSTRACT Biomass‐derived hard carbon anodes receive remarkable prospects for use in sodium‐ion battery technology. However, precise regulation of carbon crystallites is extremely critical yet formidable, which seriously retards its scale‐up industrialization. Herein, a versatile...

Asymmetric interactions in the Hawk–Dove game enhance evolutionary complexity and resource utilization efficiency

The Hawk–Dove game is one of the most important theoretical models in evolutionary game theory. To reveal the coupling effects of symmetric and asymmetric interactions on the Hawk–Dove game, we investigate the evolutionary dynamics of a newly constructed Hawk–Dove game composed o...

MACF1 condensates serve as molecular rheostats translating mechanical stress into bone adaptation

Bone dynamically maintains homeostasis through mechanotransduction, a process essential for skeletal integrity and frequently disrupted in disease. Yet how bone cells decode mechanical cues into adaptive responses remains poorly understood. Here, we identify MACF1, a cytoskeletal...

Photo-downregulation of SIRT4 mitigates aging in mice by enhancing H3K9ac via fatty acid metabolism

Abstract As organisms age, mitochondrial metabolic activity declines, and disrupted gene expression regulation mediated by histone acetylation induces the emergence of senescent physiological phenotypes in tissues. In this study, we found that periodic exposure to red light signi...

Deuterium Magnetic Resonance Imaging Tracking of Deuterium Gas Releasing from Microneedle Patches for Wound Healing as a Stable Isotope Analogue of Hydrogen Gas Therapy

Abstract Hydrogen gas therapy has attracted considerable attention for the treatment of oxidative stress-related diseases owing to its excellent biosafety, selective antioxidant activity, and anti-inflammatory effects. However, its small molecular size, rapid diffusion, and short...

Cooperative Shunt Photocatalysis of Pt Single Atoms and Nanoparticles for Efficient Methanol Conversion to Hydrogen and Formaldehyde

ABSTRACT Photocatalytic methanol dehydrogenation requires not only charge separation but, more critically, synchronized and rapid consumption of photogenerated electrons and holes—an unmet challenge in conventional Pt‐based photocatalysts. Here we report a photocatalytic platform...

Radar-vision-V2X fused perception based intelligent control mechanism for service-oriented traffic signals

Traditional traffic signal systems lack the capability to perceive vehicle types and real-time traffic flow dynamics, particularly in identifying priority levels for emergency vehicles. To address this, an intelligent traffic flow decision-making and scheduling system based on ra...

Propagation-physics-guided channel augmentation and temporal–spectral fusion for domain-robust underwater acoustic target recognition

Underwater acoustic target recognition (UATR) is essential for ocean-intelligence sensing, but deep learning-based models often suffer from performance degradation under ocean acoustic domain shift. This problem arises because ship-radiated noise recorded under different propagat...

Harnessing hydrogel technology for advanced periodontitis therapy: A multifunctional approach to oral health restoration

Periodontitis is a bacterially driven inflammatory disease that can lead to tooth mobility and tooth loss. Conventional non-surgical therapy, antibiotics, and surgery may be limited by residual subgingival biofilms, antimicrobial resistance, and variable clinical outcomes. This r...
