Biotin‐Engineered Phenothiazine Photosensitizer Boosts Type I Photodynamic Therapy via Singlet‐Excited‐State Electron Transfer

Comprehensive Summary Type II‐dominant photosensitizers often suffer from reduced photodynamic efficacy under tumor hypoxia. We report a biotin‐modified phenothiazine photosensitizer termed DHU‐Blue‐7, which converts type II methylene blue (MB)‐like photosensitization into a type...

Enhanced tidal level forecasting: A hybrid CEEMDAN-LSTM framework with Bayesian optimization

Accurate tidal forecasts are crucial for preventing flood disasters and saltwater intrusion caused by high tides. To this end, this study proposes a hybrid CEEMDAN–LSTM–BO framework to improve tidal forecast accuracy. First, the Complete Ensemble Empirical Mode Decomposition with...

Multimodel fuzzy predictor-based distributed game-theoretic formation control of underactuated autonomous surface vehicles

This paper investigates a distributed game-theoretic formation control problem for underactuated autonomous surface vehicles (ASVs) with potentially conflicting individual objectives. A distributed game-theoretic formation control framework is developed, in which formation coordi...

Does physical climate risk affect executive pay? Empirical evidence from the extreme heat weather

Purpose This study aims to examine the impact of extreme heat on executive compensation and further investigate how executives’ risk aversion moderates this relationship. Design/methodology/approach This study draws on a sample of Chinese A-share listed firms on the Shanghai and...

Urban- and Block-Scale Road Network Quality from the Perspective of Walking Needs: Research Progress and Future Directions

Road transport is indispensable to urban functioning. As people-centered development and community-oriented planning have gained prominence, pedestrian environments and road network quality have received increasing attention. Existing reviews, however, generally examine either ci...

Experimental identification and robust optimization of spindle–bearing systems with reliability constraints

Effective vibration control and dynamic behavior management in the presence of parameter uncertainties are critical for high-speed motorized spindles. Although traditional robust design optimization minimizes dynamic response variability, it lacks explicit control over failure pr...

Photothermal‐Modulated Electrohydrodynamic Jet Printing of Flexible and Recyclable Photocatalytic Devices for Visible‐Light‐Driven Water Purification

ABSTRACT Powder‐based heterojunction photocatalysts suffer from aggregation, difficult recovery, and secondary pollution, limiting their practical applications in water remediation. Here, we develop a photothermal‐modulated electrohydrodynamic jet printing (PME‐Jet) strategy assi...

Hydrogen-Bond-Mediated Molecular Interface Engineering for High-Performance CO2 Separation Mixed-Matrix Membranes

Abstract Metal-organic framework (MOF)-based mixed-matrix membranes (MMMs) are promising for CO2 separation but remain limited by poor filler–polymer compatibility and compromised molecular sieving at high filler loadings. Herein, we developed a hydrogen-bond-mediated molecular i...

Field Investigation of the Lateral Melting Rate of Ice Layers

Under global warming, lateral melting plays an increasingly important role in heat exchange between ice and water. However, field-based observations of its depth-dependent behavior remain limited, hindering the development of reliable parameterizations. To address this, we perfor...

RASR: Retinex-Guided Adaptive One-Step Diffusion for Low-Light Image Super-Resolution

Low-light image super-resolution aims to recover normal-light high-resolution images from dark low-resolution observations captured by image sensors, in which illumination attenuation, sensor noise, blur, and low resolution are entangled, making it more challenging than conventio...

Ti3C2Tx Nanosheets-Modified Phase Change Microcapsules with Thermally Induced Heat Transport Switching for Battery Thermal Management and Thermal Runaway Propagation Mitigation

Abstract Microencapsulated phase change materials for battery thermal regulation require efficient heat transport during normal operation and thermal resistance during thermal runaway propagation. MXene modified inorganic phase change microcapsules (IPCM/MXene) were prepared by i...

Modeling Impact of Crack Density on the Performance of the Microporous Layer in PEMFCs

Abstract The crack density (CD) of the microporous layer (MPL) has a positive impact on the water management and electrochemical performance for PEMFCs. As there is still a lack of strategies for designing optimal CD under varying relative humidity (RH) for enhancing MPL performa...

Performance trade-offs of free-piston engine generator through trajectory optimization and segmented trajectory-tracking strategy: Stability, indicated thermal efficiency and net generation efficiency

Free-piston engine generators eliminate the crankshaft connecting rod mechanism of conventional internal combustion engines, offering the advantage of a variable motion trajectory, but suffering from poor operational stability and weak disturbance rejection. Therefore, this paper...
