Owing to their excellent optoelectronic properties and deposition via simple solution process, metal halide perovskites possess unique potential for developing halide perovskite-based LEDs (PeLEDs) with superior photoluminescence efficiencies leading to external quantum efficiencies beyond 20% for PeLEDS. However, the limited durability, high operative voltages, and challenges of scale-up are persisting barriers in achieving required technology readiness levels. To build up the existing knowledge and raise the device performance this review provides a state-of-the-art study on the properties, film and device fabrication, efficiency, and stability of PeLEDs. In terms of commercialization, PeLEDs need to overcome materials and device challenges including stability, ion migration, phase segregation, and joule heating, which are discussed in this review. We hope, discussions about the strategies to overcome the stability issues and enhancement the materials intrinsic properties towards development more stable and efficient optoelectronic devices can pave the way for scalability and cost-effective production of PeLEDs.</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":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10575846/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41187766","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}

Although mid-turbinate sampling is an alternative, it has a lower diagnostic yield than NP sampling. Nasal wash (NW) has a similar diagnostic yield to NP sampling, but is cumbersome to perform. In this study, we introduce a 3D printed fluidic swab (3DPFS) that enables easy NW sampling for COVID-19 testing with improved diagnostic yield. The 3DPFS comprises a swab head, microchannel, and socket that can be connected to a syringe containing 250 µL of NW solution. The 3DPFS efficiently collects nasal fluid from the surface of the nasal cavity, resulting in higher sensitivity than CS for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This was confirmed by both reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and lateral flow assays (LFA) in virus-spiked nasal samples and clinical samples. Additionally, users reported greater comfort when using the 3DPFS compared to CS. These findings suggest that the 3DPFS can improve the performance of COVID-19 testing by facilitating efficient and less painful nasal sample collection.</p></div>","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"10 1","pages":""},"PeriodicalIF":11.7,"publicationDate":"2023-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10505115/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10359322","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}

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}
