This review explores various AM techniques that utilize liquid resin specifically for fabricating products aimed at treating water and wastewater. Various research studies were retrieved from Scopus and Google Scholar databases, with a time range from 2014 to 2025. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted for selecting the studies; out of 552 studies, 223 were fully examined and used in this study, and the selected studies were determined based on its relevancy to wastewater treatments, resin-based AM, and how it is being utilized to remediate water pollutants. It also highlights recent advancements in 3D-printable resin-based functional materials for removing pollutants, including dyes, heavy metals, oil, and pharmaceuticals. Additionally, the integration of these 3D-printed structures with other chemical compounds to enhance their functionalities is discussed. While 3D-printed resin-based structures demonstrate significant versatility and effectiveness, the adoption of AM in wastewater treatment has lagged compared to other sectors due to various technical and environmental challenges. Key concerns include the potential leaching of toxic resin components into the environment and the scalability of AM-based treatment systems. Despite these issues, the ability to customise and functionalize resin materials offers promising avenues for creating multifunctional structures tailored for pollutant remediation. This review highlights not only the strengths of resin-based AM, particularly in enabling durable and adaptable designs, but also the pressing challenges that must be addressed. A balanced understanding of these factors is essential for optimizing resin-based AM techniques and accelerating their integration into sustainable water and wastewater treatment solutions.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"45 ","pages":"Article e01525"},"PeriodicalIF":8.6,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605536","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}

ERAM's durability was assessed via laboratory mechanical tests, service life predictions, and field observations. A comprehensive lifecycle cost and carbon emissions analysis was conducted across multiple pavement schemes, considering complete lifecycle stages and data variability. Results show that ERAM with 60 % RAP substitution achieves a fatigue endurance limit of 191 με, substantially exceeding the field tensile strain of 53 με. Based on mechanical-empirical models, ERAM is predicted to have a service life of 27–29 years, about 170 % that of GRAM. With enhanced durability and higher RAP content, ERAM reduces annual lifecycle costs and carbon emissions by 10 % and 30 % compared to EAM and GRAM, respectively.

Water electrolysis to produce hydrogen is an ideal clean energy choice because of its high energy density and zero carbon emissions. However, fresh water, which accounts for less than 3 % of the worlds water supply is a high demand resource for people's livelihood. Seawater on the other hand, accounts for more than 70 % of the earth, making it much desirable as a source of hydrogen. For seawater to produce hydrogen, a more efficient, stable and longer-lasting catalyst would need to be developed. This would avoid chlorine evolution, a ‘competition’ reaction during oxygen evolution reaction (OER), which accelerates the corrosion process suppressing the lifespan of the catalyst. High entropy materials (HEM), a potential promising catalyst candidate, are able to reach much lower OER overpotentials and higher corrosion resistance due to their tunable electronic structures. In this work, we used a pulsed laser irradiation scanning on mixed salt solutions (PLMS) method to produce a six element, high entropy ceramic nanoparticles as an OER catalyst for efficient and stable work in seawater environments (Yang et al., 2021). The (AlCoCrFeMnNi)O high-entropy ceramic (HEC) we proposed demonstrate a great performance in the seawater environment. The onset voltage of oxygen-evolution can reach as low as to 1.47 <em>V vs.</em> reversible hydrogen electrode (RHE), and in terms of stability, our catalyst can operate for 1000 h under 100 mA/cm². Furthermore, to understand the mechanism behind our (AlCoCrFeMnNi)O HEC, the <em>in-situ</em> X-ray absorption spectroscopy (XAS) measurement and <em>In-situ</em> extended X-ray absorption fine structure (EXAFS) are carried out in this work with varying applied voltages for OER. Co, Mn, and Ni identified as the active sites of OER and these three elements work intimately together, each with different reaction routes, including the adsorbate evolution mechanism (AEM) and lattice oxygen-participated mechanism (LOM). While Al, Cr, and Fe are not directly linked to the catalytic activity, they do play important roles to stabilize the high entropy structure throughout the whole reaction. Finally, a computational model was created using a 2x1x2 supercell to study various atom distributions. This study utilizes DFT calculations, geometry optimization, and electron density mapping.

Spin polarization assists in enhancing charge transport and reduced recombination rate in PEC systems by leveraging the spin degree of freedom of electrons. The unique electronic configuration of Co³⁺ and Co²⁺ in ZnCo₂O₄ (ZCO) provides a foundation for spin polarization due to the splitting of Co 3d orbitals into e_g and t_2g energy levels, thereby exhibiting distinct spin states. Upon external perturbations such as laser irradiation and an applied bias voltage, these spin polarized electrons can facilitate efficient charge separation. This study, thus, aims at providing the first of its kind analysis of p-type ZCO semiconductors as a photoelectrocatalyst. The spin-to-charge effects on photocurrent density were analyzed using 405 and 808 nm lasers. We observe that under an applied bias potential and simulated solar light exposure, the photocurrent density increases proportional to the porosity and rising calcination temperature of ZCO.

This study aims to systematically assess the feasibility of multifunctional asphalt mixture (MAM) containing SS and carbon fiber (CF) for crack monitoring and self-healing. Firstly, the MAM was prepared by incorporating SS and CF into the asphalt mixture. Then, the conductive, thermal, microwave heating, self-healing, and road properties of the MAM were comprehensively evaluated through a series of laboratory experiments to determine the optimal combination formula of SS and CF. Based on this, the crack of the MAM was monitored by the digital image correlation (DIC) technique and digital acquisition and recording system (DARS) to evaluate the ability of the MAM to sense the damage evolution. Finally, the effect of different healing moments on the healing efficiency of the MAM was investigated. The results show that the incorporation of SS and CF can significantly improve the conductive properties of asphalt mixture, providing the necessary electrical basis for the MAM to achieve the crack monitoring function. The MAM containing SS and CF exhibits excellent microwave heating efficiency and acceptable microwave heating uniformity, which contributes to improving the self-healing properties of asphalt mixture. Based on the multi-index optimization results, a combination formula of 50 % SS replacement and 0.15 wt% CF is recommended that could achieve ideal comprehensive performance. The cracks in MAM can be monitored in real time through the variation of the electrical signals, and efficient healing can be achieved by adopting microwave heating at the microcrack stage (i.e., crack size &lt;400 μm).
