We have successfully initiated the utilization of waste rubber bands into triboelectric nanogenerator (TENG) technology by an economic, simple, and eco-friendly chemical processing of waste rubber bands to fabricate a high-performance negative tribo-layer. Due to the strong triboelectrification between the waste human hair film and the waste rubber band film of complementary surface structures, a powerful electrical output of 7.24 KV and 196.44 μA, along with a high output power density of 28,459.43 μWcm<sup>−2</sup>, was generated from a fabricated bio-TENG with dimensions of 5 × 10 cm<sup>2</sup>, which represents a significant improvement over the recent advances in waste material-based TENGs. The lightweight and flexible rubber band-based negative side of the TENG device is capable of efficiently harvesting friction with natural hair and human finger tapping with significant selectivity, thereby exhibiting excellent prospects in self-powered smart human health monitoring. By realizing the systematic utilization of slowly degradable waste materials in TENG devices, we not only solve a problem in waste management systems and mitigate serious environmental issues but also pave the way for developing large-scale, cost-efficient, green self-charging power cells and self-powered modern health care applications.

This study introduces a precise colour imitating strategy for champagne satin silk combining the extract of invasive <em>Eupatorium adenophorum</em> (EAE) with metal mordant. Importantly, a referable approach based on mathematical simulation is developed for controllable mordant dyeing process. Research found that the main components in the EAE are two flavonoids (marigold glycoside and 4′-methyl ether marigold glycoside). The stability of EAE is well remained in water under heating below 100 °C for up to 60 min which lays fundamental in its application on textiles. In terms of the mordant types, the silk dyed with EAE/Ti<sup>4+</sup> exhibits much closer colour hue to the targeted champagne colour than those with EAE/Al<sup>3+</sup> or EAE/Fe<sup>3+</sup>. The <em>a*</em> and <em>b*</em> value dots are well distributed along with the fitting line indicating their good linear relationship. Such result demonstrates the stable colour hue of EAE/Ti<sup>4+</sup> dyed silk, and the colour saturation is manageable by altering the concentration of EAE/Ti<sup>4+</sup> couple during dyeing. Based on the established relationship between the EAE/Ti<sup>4+</sup> concentration and <em>K/S</em> value, a theoretical mordant dyeing condition (EAE for 72.38 % owf and Ti<sup>4+</sup> for 0.81 g/L) is generated to achieve the target <em>K/S</em> value. After washing, the silk dyed with EAE (100 % owf) and Ti<sup>4+</sup> ion (0.4 g/L) restricts the <em>K/S</em> variation from 57 % to 16 % compared with the case without mordant. However, over loading of Ti<sup>4+</sup> ions reversely reduces the fastness. Additionally, the UPF of treated satin silk exceeds 98. In general, this study establishes a new method for colour imitation of synthetic dyed silk using invasive plant extract, which pushes forward the development of natural dyeing and functionalization techniques.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"43 ","pages":"Article e01292"},"PeriodicalIF":8.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigates the workability, compressive strength and alkali-silica reaction (ASR) of Portland cement (PC) and alkali-activated cement (AAC) mortars containing NS and recycled sand (RS). Compared to NS, the higher water absorption characteristic of RS leads to the decrease flowability of fresh mortars. The compressive strength of AAC mortar containing RS is comparable to that of AAC containing NS, while the compressive strength of PC mortar containing RS presents obvious decrease. Pore structure analysis shows that the use of RS has negative impact on the densification of microstructure. This is more obvious in the PC system, which is one of the reasons for the decrease of strengths. It can be found that, with the use of RS, the lower alkalinity and less available calcium in pore solution are beneficial for the mitigation of ASR in PC system. While the soluble aluminum species contributes to the rapid formation of gel layer covered on the RS surface in AAC system, and thereby inhibiting the further dissolution of silica from NS and controlling of ASR expansion.
