NaAlO2 showed the highest activity while Ca(OH)2 exhibited enhanced performance at low amounts. The yield was correlated with point impact energy rather than total energy. The catalyst and impact energy must be optimized for efficient conversion.Polycarbonate (PC) is an engineering plastic that combines high optical transparency with outstanding mechanical toughness. The unique properties of this material have led to its extensive use in automotive, medical and optical applications 1,2 . Even so, PC is categorized as \"Other\" (Code 7) in the ASTM International resin identification code system 3 , and dedicated recycling streams for post-consumer PC are less established than those for commodity plastics such as polyethylene terephthalate and high density polyethylene 2 . While the use of other polymers or the development of bio-based PC has attracted increasing attention as a sustainable alternative to PC 4,5 , such materials often do not exhibit the physicochemical characteristics required for practical applications. Accordingly, the search for effective, sustainable PC recycling strategies has become a priority.The chemical recycling of plastics has a notable advantage over mechanical recycling in that high-quality recycled materials can be obtained regardless of the degree of degradation [6][7][8] . Because the carbonate linkages in PC are susceptible to transesterification, this material can be depolymerized into bisphenol A (BPA) and dimethyl carbonate (DMC) using alcohols. Methanol is most commonly employed for the depolymerization of polyesters and PC because the small molecular size and high reactivity of this alcohol facilitate transesterification reactions 1,9 .

{"title":"Visible-Light Photoactivated Carbon Dots for Antiviral Applications: From Photophysical Mechanisms to Functional Surfaces","authors":"Plinio Innocenzi","doi":"10.1039/d6cc06372a","DOIUrl":"https://doi.org/10.1039/d6cc06372a","url":null,"abstract":"Photoactivated carbon dots (C-dots) are a promising class of antiviral nanomaterials capable of inactivating viruses through light-driven oxidative processes. Unlike conventional antiviral drugs, which target specific viral proteins and can therefore be affected by viral mutation and resistance, photoactivated C-dots operate through multi-target mechanisms. These involve the generation of reactive oxygen species (ROS) that cause oxidative damage to viral envelopes and proteins. However, the extraordinary structural diversity of C-dots has often obscured the relationship between their physicochemical properties and antiviral performance. This review discusses antiviral C-dots considering the interplay between virus–nanomaterial interactions, electronic structure, and photochemistry. The primary focus is on visible-light-activated C-dots and surfaces, not on clinical photodynamic therapy. Attention is given to how surface charge, functional groups, and multivalent effects regulate nanoparticle–virus association, while the nature of the electronic states, ranging from molecular-state-dominated systems to hybrid core–surface architectures and graphenic nanoparticles, governs excited-state dynamics and ROS generation pathways. The review also discusses visible-light-responsive systems and the central role of triplet-state engineering and singlet-oxygen production in efficient viral inactivation. Representative case studies illustrate how distinct electronic architectures can be designed to promote either broad-spectrum oxidative activity or efficient singlet-oxygen-mediated photochemistry. The article also discusses the transition from colloidal suspensions to the fabrication of functional antiviral surfaces. By linking antiviral activity to fundamental photophysical and interfacial processes, this article provides a framework for rationally designing next-generation visible-light-activated antiviral materials and self-disinfecting surfaces.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"14 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
