Based on existing studies, we identified that the heat sinks used in wearable thermoelectric coolers (WTECs) are predominantly bulky, which limits their practicality and comfort. To address this issue, propose use of phase-change composite materials (PCCMs) due to inherent flexibility thermal properties. Through comprehensive theoretical analysis, numerical simulations, experimental validation, successfully optimized design a WTEC.
The rapid advancement of flexible electronics and wearable sensors has heightened demands for stretchable structures that excel in conformability, dynamic motion adaptability, stability under cyclic stretches, antidistortion properties, holding significant commercial value. Traditional designs have often compromised the fill factor to achieve in-plane stretchability by incorporating electrodes with or prestrained architectures. In this article, we introduce a novel bidirectional spiral-hinge...
In order to investigate the enhancing effect of basalt fiber (BF) on toughness asphalt, BF modified asphalt and mixture were prepared. Strip tensile test was performed study anti-cracking ability asphalt. The investigated using MTS system. SEM conducted explore mechanism BF. results showed that ultimate stress peaked when content reached 0.4% by weight mixture. Composite materialization self-healing force led capacity
This study investigated the purifying effect of tourmaline-modified asphalt on automobile exhaust. Six types concrete were prepared, aiming to achieving excellent exhaust-purifying performance. The slabs exhaust was emulated indoors through using an exhaust-gas analyzer and a self-made air purifier chamber in cooling process specimens. Then, influence laws rate slabs, dosage tourmaline, method tourmaline being added upon performance studied systematically. mechanism analyzed thermoelectric...
Three novel asphalt modifiers with pollutant emission reduction effects and new emissions measurement equipment compatible several preexisting production systems are developed in this paper. The of various modifier, binder type, gradation hot mix (HMA) on evaluated the lab through a comprehensive experimental design. Furthermore, road performances monitored to evaluate modified HMA mixture for production. With increasing modifier content, performance is improved markedly, maximum 70.5%....
In order to investigate the effect of nano polymer materials on UV aged performance asphalt binder, a PA modifying agent was selected prepare modified asphalt. Under radiation, rheological properties studied. With extension ageing time, microstructure variation characterized by using focused ion beam scanning electron microscope (FIB-SEM).

The purpose of this study was to characterize and evaluate the effects UV radiation on rheological physicochemical properties ASA polymer-modified asphalt. conventional (penetration, softening point, ductility, Brookfield viscosity) asphalt were tested. Based rheology, effect different irradiation times high-temperature performance systematically characterized, thermogravimetric analyzer (TGA) used analyze asphalt, micromorphological characteristics ASA-modified under characterized by...
The purpose of this study is to improve the evaluation accuracy cooling effect road coatings using a new data processing method based on Grubbs and linear regression exclude abnormal values accuracy. Five kinds pavement are developed as main objects study, whose performances could fulfil requirement current asphalt pavement. We have also selected optimal variable for coatings. It found in that correlation coefficients different effects' formulas remained around 0.99, suggesting there...
Abstract To clarify the effect of Hindered amine light stabilizer (HALS) on ultraviolet (UV) aging behavior asphalt binder, evolution history and characteristics UV induced micro-structure modified were characterized. Scanning Electron Microscope (SEM) Atomic Force (AFM) used to analyze microscopic morphology stabilizer-modified during aging. By defining in joints by UV, identification classification typical are proposed. On this basis, an evaluation method based process was proposed...
