The ability of self-healing concrete (SHC) to successfully heal fractures without the assistance of humans has received much attention since it increases operational life and lowers maintenance expenses. This paper reviews various techniques and technologies of autogenous and autonomous self-healing concrete. Much more attention is given to the autonomous SHC, including the encapsulation materials, capsule geometries, and healing agents. This is due to its accuracy for healing locations and better healing capabilities compared to the uniform hydration of autogenous SHC. Polymeric materials have shown great potential in both capsules and healing agents. Because they can meet the unusual demands of capsules, which include being flexible when mixing concrete and becoming brittle when cracks develop, the healing agent's viscosity must be low enough to allow it to flow out of the capsules and fill tiny cracks. In contrast, if the viscosity is too low, the healing agent will either seep out of the fracture or be absorbed by the pores of the concrete matrix. Additionally, some projects have been cited to demonstrate the feasibility of self-healing concrete in the construction industry.","PeriodicalId":87352,"journal":{"name":"Recent progress in materials","volume":"16 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140442442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular was focused on Nanoassemblies such as vesicles, micelles and lipidic Nanoparticles; and incorporating as well insights from other types of Nanomaterials that could afford to develop new organized systems. It should be noted that in these cases the term organized system was used for all types of molecular assembling and Supramolecular systems that formed structures within the Nanoscale. By this manner the incorporation of Opto-electronic active materials permitted to develop very important photo-physical phenomena with high impact perspectives within technology and Life Sciences. Thus, it was leaded to discuss the participation of Carbon based chemical structures incorporated in different confined molecular media to develop i) Electron Transfer (ET) processes; ii) Reaction Electron Transfers (RET); iii) Catalysis; iv) Quantum emissions; v) Fluorescence Resonance Energy Transfer (FRET); vi) non-classical Light; and vii) Nano-Optics. Therefore, it was intended to present the most important physical and chemical phenomena where they could participate as functional high electronic conjugated chemical structures.","PeriodicalId":87352,"journal":{"name":"Recent progress in materials","volume":"10 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140479088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, per- and polyfluoroalkyl substances (PFAS), which pose potential risks to the environment and human health, commonly exist in landfill leachate due to their wide application in various industrial and consumer products. Therefore, removing UVQS and PFAS from landfill leachate is crucial. In this work, the advances in removing UVQS and PFAS from landfill leachate in the last decade are reviewed to find a standard treatment for both contaminants to lower the costs and space required for the leachate treatment process. The benefits and drawbacks of biological, physical, chemical, and electrochemical treatments were examined. Physical, chemical, and electrochemical treatments showed advantages over biological treatments but higher energy and/or material costs. The global analysis indicated that similar technologies, such as adsorption or osmosis, can be used as effective methods to remove UVQS and PFAS from landfill leachate and suggested that both types of pollutants could be eliminated simultaneously with a single treatment based on one of these two technologies.","PeriodicalId":87352,"journal":{"name":"Recent progress in materials","volume":"2 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139602477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Design and synthesis of highly pure materials such as Graphene, Carbon Nanotubes, fullerenes, and other Carbon-based allotropes were shown. They presented their most important and promising properties concerning new studies and developments in photonics. Carbon-based Quantum dots, semiconductors, and higher sized Nanoplatforms allowed us to discuss fundamental studies and perspectives within varied applications. In this context, relevant developments from literature related to electron transfer within various targeted processes, where energy and light transfers occurred through different optical active materials and platforms, were highlighted and discussed. Therefore, many approaches that tuned the desired Optical active properties were shown. Thus, Hybrid materials from single Quantum and Nanoplatforms towards modified substrates were incorporated within varied media such as colloidal dispersions, solid devices, and waveguides. Moreover, Heterojunctions and applications such as energy harvesters and emitter devices were also presented. This manner highlighted varied topics of Photonics' leading current status, perspectives, and implications in Nanophotonics, Quantum photonics, and Optical lenses. Further views and commentaries about Green Photonics were presented as well.","PeriodicalId":87352,"journal":{"name":"Recent progress in materials","volume":"103 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139154906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
