An e-HMS-PDMS silica gel nanoparticle coating was prepared using a two-step electron beam irradiation (EBI) process, consisting of (i) grafting of two organic groups onto thiol-functionalized hollow mesoporous silica (HMS-SH) with 10 MeV EBI and (ii) curing of polydimethylsiloxane (PDMS) onto silicone rubber using the HMS hybrid materials prepared in step i as an additive with 200 keV EBI. The tuneable grafting of functional groups and the surface properties of the silica, which was embedded in the PDMS layer, allowed us to precisely control the hydrophilicity of the PDMS layer by means of altering the grafting gradient of the silica and the loading ratio of the monomers. A diverse range of vinyl-structured monomers can be used in this method, and the selection of suitable monomers is vital in determining the physical properties of the coating layer. The hydrophilicity of the coating can be linearly controlled within a specific range (50° to 155°) by using suitable monomers, allowing for the design of surfaces with specific hydrophilic and hydrophobic requirements.</p><p>Keywords: Electron beam irradiation; Nanoparticle composite coating; Hydrophilicity/hydrophobicity; Thiol-ene click reaction.</p>","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 3","pages":" 458-468"},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/im/d4im00015c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140882908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Carboxylic ligands to enhance material recovery from construction waste to produce CaCO3 for carbon utilization†","authors":"Jonah M. Williams, Diandian Zhao, Ning Zhang, Shiho Kawashima and Aaron J. Moment","doi":"10.1039/D4IM00025K","DOIUrl":"10.1039/D4IM00025K","url":null,"abstract":"<p>The decarbonization of the built environment is a pressing issue to achieve CO<small>₂</small> reduction targets in the concrete industry. Carbon mineralization of construction and demolition waste (C&amp;DW) is an attractive pathway to capture of CO<small>₂</small> as stable carbonates which can be re-utilized and upcycled in a circularized fashion through the creation of new building blocks. Material recovery from the C&amp;DW is often performed in hydrometallurgical leaching using acidic media; however, this process is often hindered by solubility issues and passivation. To ensure high recoveries of these elements, ligands can be used to enhance dissolution. Carboxylic acids are used in conventional hydrometallurgical mineral processing, such as leaching, floatation, and solvent extraction, and are desired due to their affordability and stability. In this study, we explore the dissolution of waste cement pastes in acidic conditions under the presence of four carboxylic acid ligands: formate, acetate, glutamate, and citrate. The leaching kinetics are categorized and the pseudo-rate constants are established, demonstrating the advantages of these agents to enhance reaction rates in the general order of citrate ⋙ formate &gt; acetate &gt; glutamate &gt; control. The characterization of the post-extraction reactor residue (PERR) revealed a significant increase in Si-content. Finally, the leachate was carbonated to produce calcium carbonate, which was characterized for its use based on morphology and size. Glutamate demonstrated distinct advantages compared to other ligands, with a dual function of not only improving leachability of cement but promoting and stabilizing vaterite during crystallization. Overall, this study motivates the use of sustainable ligands to enhance material recovery during the dissolution of alkaline wastes for carbon mineralization.</p><p>Keywords: Carbon mineralization; Material recovery; Leaching; Ligands; Carboxylic acids; Calcium carbonates; Carbon capture utilization and storage.</p>","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 1","pages":" 69-86"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/im/d4im00025k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140835917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The channels present within the catalyst layer of MEAs exhibit a disordered configuration, which consequently give rise to low efficiency in mass transportation.

We synthesized TiN nanorod arrays on the ITO surface by a seed-assisted hydrothermal reaction and nitriding treatment, and coated the catalyst uniformly on the TiN support by ultrasonic spraying. Then the double-side ordered MEA was fabricated by transfer printing, and achieved a peak power of 678.30 mW cm<small>⁻²</small> with a cathode platinum loading of 0.2 mg cm<small>⁻²</small> at 80 °C and anode saturated humidity.
