Abstract Increasing demand for energy globally, with the building sector being a significant contributor to consumption, is major issue. To address this, efforts are made make buildings more efficient, including lowering heating, ventilation, and air conditioning decrease demand. Phase change material (PCM) functions as latent heat storage that absorbs while transforming its phase from solid liquid then releases when it transforms state. Integrating PCM into materials can considerably enhance their density. In this study, potential of using fly ash cenosphere—capric acid (CeCA) composite in concrete evaluated. The mechanical, durability thermal properties CeCA blended were investigated. Furthermore, CeCA‐concrete enhanced auxiliary cementitious substance, namely ground granulated blast furnace slag (GGBS). optimal proportion was determined ensure balance compressive strength conductivity. results indicated lowered an increase percentage CeCA. conductivity specimen by 33.14% at 25% incorporation CeCA, resulting improved performance. GGBS has mechanical performance CeCA‐Concrete. found be +40% GGBS, which had greater efficiency than control similar findings validated field emission scanning electron microscopy analysis specimen.

Phase change materials (PCMs) are that exhibit thermal response characteristics, allowing them to be utilized in the biological field for precise and controllable temperature regulation. Due considerations of biosafety spatial limitations within human tissue, amount PCMs used medical applications is relatively small. Therefore, researchers often augment with various enhance their performance increase practical value. The dispersion nanoparticles modify thermophysical properties has emerged as a mature concept. This paper aims elucidate role nanomaterials addressing deficiencies enhancing PCMs. Specifically, it discusses methods stabilization mechanisms PCMs, well effects on such conductivity, latent heat, specific heat capacity. Furthermore, explores how nano-additives contribute improved conductivity underlying enhanced heat. Additionally, potential biomedical fields proposed. Finally, this provides comprehensive analysis offers suggestions future research maximize utilization applications.

Carbon fiber (CF) is one of the conductive fillers with best electrical conductivity, but it expensive and difficult to disperse in cement matrix, which limits application development CF cement-based composites. Therefore, this paper took slurry content 1.0 % as control group, proposed use low-cost graphite (G) nano-carbon black (NCB) instead some CFs prepare The synergistic enhancement effect between different was explored reduce cost materials while maintaining conductivity. results showed that resistivity decreased first, then increased, increased increase proportion particle filler CF. 125.65 Ω·cm when G replaced 20 CF, 140.66 NCB 30 122.05 were close group (122.35 Ω·cm). purpose reducing without affecting conductivity achieved.
