Hailed as the ‘anti-Instagram’ or ‘anti-TikTok’, the app eschews filters, performance, influencers, and sponsored content in favor of authenticity. While curated authenticity has long been a hallmark of internet culture, BeReal seems to employ authenticity not as a performance strategy but as a value, tapping into criticisms of the inauthentic. Through the walkthrough method of social media app analysis, I employ ethnographic research tenets to analyze how BeReal forwards a different type of authenticity to its users from its discourse, design, interface, and features. The findings are two-fold: First, BeReal privileges authenticity-as-realness instead of authenticity-as-performance, using spontaneity and timed posting windows to severely limit the time one can craft a post. Second, BeReal acts as a panopticon, because the omnipresent possibility of posting means users are always already aware of the potential. Authenticity-as-realness is not uncomplicated; it relies much more heavily on neoliberal self-monitoring and panopticism to be ready for anything, as opposed to a finely tuned and intricately crafted performance with lighting, makeup, and editing. This indicates considerations of authenticity are changing on social media platforms, putting performance at odds with panopticism.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"18 1","pages":"1183 - 1198"},"PeriodicalIF":11.7,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87140184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By this term, the authors refer to a material process implying the chronic use of graphic editors, semi-automatic keywording allowing complex and dynamic proto-classifications, and access to the images via search engines. The algorithmization of microstock imagery also goes along with the exploitation of producers’ labour, so that the authors recognize in it a form of digital labour. Moreover, the term ‘algorithmization’ is meant to underline that this material process has symbolic effects on the image contents as well as on people’s expectations and imaginaries of these contents. The paper analyses, in particular, the case study of microstock images depicting artificial intelligence (AI). By producing hundreds of thousands of visual representations of AI that spread via the Web and beyond it, algorithmized microstock imagery also produces its own symbolic conditions of possibility, that is, the expectations and imaginaries that contribute to the success of AI beyond its concrete effectiveness. The paper is structured into three sections. In the first section, the authors account for the existing literature on stock imagery. They contend that this literature focuses too much on the symbolic message, and too little on the material processes of production of these images. In the second section, the authors describe an empirical analysis they conducted on Shutterstock images depicting AI. In the third section, they distinguish three forms of digital labour and show that microstock imagery entertains resemblances to and differences from each form. They contend that despite its peculiarities, microstock image production is a paradigmatic form of digital labour due to its convergence towards algorithmization. In the conclusion, the authors show how, for microstock images depicting AI, the algorithmic loop of microstock imagery is complete.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"27 1","pages":"1226 - 1242"},"PeriodicalIF":11.7,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82080661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review presents the major applications of low-temperature plasma for biomass conversion in terms of (i) pretreatment of biomass, (ii) chemo fractionation of biomass into value-added chemicals, and (iii) synthesis of heterogeneous catalyst for further chemo-catalytic conversion. The pretreatment of biomass is the first and foremost step for biomass upgrading to facilitate raw biomass transformation, which reduces the crystallinity, purification, and delignification. The chemo-catalytic conversion of biomass involves primary reactions to various kinds of target products, such as hydrolysis, hydrogenation, retro-aldol condensation and so on. Finally, recent researches on plasma-assisted chemo-catalysis as well as heterogeneous catalysts fabricated <i>via</i> low-temperature plasma at relatively mild condition were introduced. These catalysts were reported with comparable performance for biomass conversion to other state-of-the-art catalysts prepared using conventional methods.</p><h3>Graphical Abstract</h3>\u0000 <div><figure><div><div><picture><source><img></source></picture></div></div></figure></div>\u0000 </div>","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"10 1","pages":""},"PeriodicalIF":11.7,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10449751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10081441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the uncontainable dendrite growth during the repeated charging process, deteriorates the battery performance, reduces the battery life and more importantly, raises safety concerns. With their unique properties, two-dimensional (2D) materials, can be used to modify various components in metal batteries, eventually mitigating the dendrite growth, enhancing the cycling stability and rate capability, thus leading to safe and robust metal anodes. In this paper, we review the recent advances of 2D materials and summarize current research progress of using 2D materials in the applications of (i) anode design, (ii) separator engineering, and (iii) electrolyte modifications by guiding metal ion nucleation, increasing ion conductivity, homogenizing the electric field and ion flux, and enhancing the mechanical strength for safe metal anodes. The 2D material modifications provide the ultimate solution for obtaining dendrite-free metal anodes, realizes the high energy storage application, and indicates the importance of 2D materials development. Finally, in-depth understandings of subsequent metal growth are lacking due to research limitations, while more advanced characterizations are welcome for investigating the metal deposition mechanism.

The monument in question, namely, the recently reconstructed and rescaled Atatürk, His Mother and Women’s Right Monument in İzmir, Turkey serves as an exemplary case for examining the reproducibility of monuments within both physical and digital environments. Its significance lies not only in the ongoing political and scholarly debate revolving around the decision of local municipality to undertake its reconstruction, but also in its growing popularity in social media as a consequence of this debate. The analyses of digital reproductions of the monument in the paper are twofold: The first gives insights into the effects of digital reproductions on the aura and authenticity of the monument in locative media. The second focuses on how the local municipality and individual users instrumentalize these productions to perform official and mundane rituals and aestheticize not only their own political agendas but also their everyday life.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"316 1","pages":"1243 - 1261"},"PeriodicalIF":11.7,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78382134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
