A source-to-sea decision-support framework for wet-weather wastewater load management: evidence from Jiaozhou Bay

Coastal concentration compliance can overlook increased wastewater throughput during wet weather. We developed a source-to-sea decision-support framework using 2019–2022 wastewater, river, and marine observations from Jiaozhou Bay, China. The analysis combined source-record audit...

Mode-Dependent Differential-Algebraic Kinematic Modeling of a Four-Wheel Wall-Climbing Robot on Cylindrical Inner Surfaces

Multi-wheel wall-climbing robots operating on cylindrical inner surfaces are subject to configuration-dependent wheel-surface contacts and nonholonomic rolling constraints, making planar differential-drive or fixed-contact kinematic models insufficient when the active contact top...

Design of a load-responsive mechanical pressure limiter for overload protection in hydraulic actuators

To improve the overload protection performance of hydraulic actuators under dynamic load variations, a load-responsive mechanical pressure-limiting device is proposed with a wheel loader as the application background. The device integrates a pressure-sensitive element, a pressure...

Dual Porphyrin Sensitized Photocatalytic System for Visible‐Light‐Driven CO 2 Reduction

Dye‐sensitized photocatalysis offers a powerful strategy for combining the molecular selectivity of transition‐metal catalysts with the robustness and charge‐separation capabilities of semiconductor materials. Herein, we report a dual porphyrin–sensitized TiO 2 platform for visib...

Molecular π‐Conjugation Engineering Enables Flexible and Water‐Resistant Organic RTP Materials for Wearable Applications

ABSTRACT Organic room‐temperature phosphorescence (RTP) materials for flexible and aquatic applications are limited by triplet exciton instability under deformation and environmental perturbation. Here, molecular π‐conjugation engineering is integrated with polymer‐matrix confine...

Effect of wave-induced motion on the energy harvesting performance of a floating solar-powered AUV

This paper proposes a novel concept of a solar-powered autonomous underwater vehicle (AUV) featuring a foldable solar wing panel. The design enables energy harvesting during surface floating operations. We investigate the time-varying energy harvesting characteristics due to the...

Research on Innovative Strategies of AIGC Empowering Corporate New Media Communication——Taking the Official WeChat Account "High-speed Rail Sifang" as an Example

Against the backdrop that AIGC has comprehensively reshaped the logic of media production, new media operated by state-owned enterprises engaged in high-end equipment manufacturing have long been plagued by practical bottlenecks, including low efficiency of content production, di...

Short-Term Stable Catchment-Level Metabolic Structure in Urban Wastewater Revealed by Untargeted Metabolomics

Background: Urban wastewater integrates chemical signals from human activities and provides a composite biochemical representation of the communities it serves. However, whether wastewater metabolomes exhibit stable spatial organization at the catchment scale remains insufficient...

Elucidating the source and metabolic impact of 2‐phenylethanol on Lactiplantibacillus pentosus 1 using a fish broth fermentation model

Abstract BACKGROUND The quality of traditional fermented sour fish is shaped by metabolic interactions between core microbiota dominated by lactic acid bacteria (LAB) and yeasts. 2‐Phenylethanol (2‐PE) is a characteristic metabolite and quorum‐sensing molecule of Saccharomyces ce...

Spatially Decoupled Electron and Lithium Storage at Fe/Solid Electrolyte Interphase Interfaces

ABSTRACT Extra lithium storage in transition‐metal nanoparticles remains debated because interfacial reactions are difficult to distinguish. Using Fe/C as a model anode, we combine in situ electron paramagnetic resonance (EPR) and magnetometry to resolve two concurrent storage pr...

Defect-engineered high-entropy spinel ferrite nanofibers via Joule heating for superior microwave absorption

Abstract Spinel ferrites with exceptional magnetic permeability, optimal impedance matching, and robust chemical stability have attracted considerable attention in high-performance electromagnetic wave (EMW) absorption applications, yet their insufficient dielectric dissipation a...

Multi-Objective Energy-Efficient Train Timetable Optimization in Urban Rail Transit via a Hybrid DRL-NSGA-III Framework

Urban rail transit systems face a pronounced contradiction between escalating traction energy consumption and passenger service quality under the carbon peaking and carbon neutrality goals. This study proposes a hybrid optimization framework offline combining deep reinforcement l...

Pore and mineral controls on petrophysical anomalies in undercompacted mudstones

Abstract In mudstones, undercompaction inhibits grain rearrangement, preserving pores and generating anomalous petrophysical responses. These anomalies typically manifest in geophysical exploration as abnormal acoustic and resistivity logs. However, the microstructural difference...
