Pre‐Intercalated Cation Optimizing Proton Topochemistry for High‐Performance Aqueous Zinc‐Ion Batteries

ABSTRACT Cation pre‐intercalated oxides have been widely explored as cathode materials for aqueous zinc‐ion batteries (AZIBs). Although the influence of intercalants on the material structure and Zn 2+ storage capacity has been adequately studied, an in‐depth understanding of the...

Agency-structure: Tourists' sustainable food journey

This study integrates visual and qualitative methodologies within a longitudinal framework to examine how agency and structure shape tourists' sustainable healthy food consumption before, during, and after holidays. Pre-holiday food practices are influenced by intergenerational k...

Public Health and Optimal Trade Policy: The Role of Immigration

ABSTRACT We determine the optimal tariff in the presence of immigration and public health provision in a factor‐abundance‐driven trade model, and we prove two results. First, ceteris paribus , a higher value of immigrant output, a more efficient or cheaper public health service,...

Aero‐breakup of droplets: Recent progress and outlook

Abstract Aero‐breakup of droplets is a classic academic topic in fluid mechanics that describes the process of droplets breaking into multiple smaller ones or fine mists in an air flow. An in‐depth understanding of the aero‐breakup of liquid droplets is essential for the applicat...

Dynamic analysis and optimal design of a pendulum rotary tuned mass damper for bidirectional control of rotational and translational vibrations

This paper proposes a novel pendulum rotary tuned mass damper (PRTMD), which primarily consists of a mass sphere, a rigid rod, a rigid ring, and a torsional spring. The proposed damper can simultaneously provide both rotational and translational control capabilities to the contro...

Interaction of physical fitness and resting state functional connectivity on global cognitive function in older adults with mild cognitive impairment

Background Mild cognitive impairment (MCI) represents a prodromal stage of Alzheimer's disease. Physical fitness, including cardiorespiratory fitness and muscular strength, is associated with cognitive function in older adults. Resting-state functional connectivity (rsFC) is also...

Real-time hydrogen gas explosion prediction from fuel cell vehicles by physics-informed graph neural network

Hydrogen fuel cell vehicles (HFCVs) generate electricity from hydrogen via electrochemical reactions and offer an efficient, environmentally friendly pathway to the dual‑carbon targets. Nevertheless, hydrogen leakage can rapidly mix with air to form large flammable vapor clouds....

Study on performance enhancement and heat transfer regulation simulation of phosphogypsum-based phase change cementitious material

Phosphogypsum-based building materials hold great promise as a key method for managing solid waste. However, their limited thermal storage capacity restricts their widespread application in engineering. In this study, microcapsule phase change materials (MPCMs) were introduced to...

Bridging Autonomous Driving and Electric-Mobility Systems: From Technical Interfaces to Cross-System Validation

Road-transport electrification and driving automation increasingly connect vehicle actions with charging services and urban electricity demand. This review combines two Web of Science Core Collection result sets with abstract-level term analysis and a structured synthesis of tech...

Transit-oriented built environment, accessibility and the intra-urban geography of innovation in Hong Kong

This study examines the relationship between transit-oriented development (TOD) and innovation outcomes at the intra-urban scale, using Hong Kong as an example. Patent data are applied to measure the level of innovation activities at the neighbourhood scale and further differenti...

How Instrumental and Expressive Ties Shape Team Resilience in Digitally Mediated Construction Projects: The Moderating Role of Communication Visibility

Abstract Construction projects often operate in dynamic environments where team resilience is vital for survival. Although social ties provide the structural potential for adaptation, the specific mechanisms that translate these connections into resilient performance, particularl...

Regret aversion and anchoring effects in advanced parking information system adoption: The behavioral economics of parking choices

Advanced parking information systems (APISs) aim to alleviate urban parking challenges by providing real-time information and reservations. Their effectiveness, however, depends on how drivers respond to these services when they coexist with uncertain current parking options. Thi...

A geometry-aware Bi-level reduced-order model for state-field reconstruction and exergy-flux evaluation in closed wet cooling towers

Tube-bundle geometry governs the coupled airflow, evaporation, heat transfer, and pressure loss in closed wet cooling towers, making repeated computational fluid dynamics (CFD) simulations costly for design under uncertain ambient conditions. This study develops a geometry-aware...

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...

On the significance of absolute and convective instabilities in transitional hypersonic compression ramp flows

In real-life tunnel or flight environments, the laminar–turbulent transition of compression ramp flows can be initiated by absolute and/or convective instabilities. Currently, the relative significance of the two instabilities in such flows remains unclear. This paper addresses t...
