- Abstract
Extension professionals often communicate program outcomes to external stakeholders using impact statements. We developed and evaluated four impact statements for the Expanded Food and Nutrition Education Program (EFNEP). We drafted the statements after conducting literature reviews for core content areas of EFNEP that include diet quality, food resource management, physical activity, and food safety. Subsequently, we evaluated the statements by facilitating expert panels made up of subject matter experts and communication professionals(n=14) from 12 Land-grant Universities. These impact statements aim to support EFNEP and other Extension professionals when communicating program value with key external stakeholders.

4. The Basic Course in Communication: A Critical Intercultural and Participatory Approach
- Author
-
Chelsea Slack
- Abstract
This paper advocates for using critical intercultural and participatory pedagogy as the basis for an introductory communication course. Communication programs are often concerned with the basics -- teaching students to communicate effectively through writing and speaking. Yet the methods for teaching these two classic competencies diverge widely, with some instructors opting for a more traditional approach and others taking a more modern one. A divide also exists in the way today's students are viewed by educators in secondary and, in particular, post-secondary educational institutions. Where some teachers see lamentable shortcomings of millennials and Gen Z, others see infinite possibilities in these students. Either way, colleges and universities are dealing with a generation of students that is more diverse, connected, tech-savvy, and socially aware than ever before. This paper explores the advantages of using critical intercultural pedagogical practices -- practices which are necessarily cooperative, multimodal, and participatory -- to reach the students of today.

Refaei, Brenda, Kumar, Rita, Wahman, M. Lauren, and Peplow, Amber Burkett
- Abstract
A cross-disciplinary team of composition, communication, and library faculty used lesson study to investigate interdisciplinary instructional strategies to improve students' use of quoting in their writing. The team developed a three-class lesson plan to introduce the concept of quoting, practice the concept, and allow students to reflect on their use of quotations in their writing. We collected a pre and post quiz to measure students' understanding before and after the lesson, students' practice paragraphs, students' reflections, and students' final course research assignments. These samples were analyzed by the research team. Our evidence suggests that students can articulate how a quote from a source should be integrated into their writing by describing how they would use a signal phrase and quotation marks, but they have difficulty in applying this complex skill in their own writing even after focused instruction on how to use quotes.

9. Thematic Analysis of Marketing Messages in UK Universities' Prospectuses
- Author

Mogaji, Emmanuel and Yoon, Hyunsun
- Abstract
Purpose: Prospective students are exposed to abundant choices, and they are eagerly searching for information to select the best universities for themselves. Likewise, prospectuses are regularly produced by universities to meet this information needs; the purpose of this paper is to examine the key marketing messages used in their prospectuses. Design/methodology/approach: The 2017 undergraduate prospectuses of 121 universities in the UK (out of the 134 members of University UK) were thematically analysed using NVivo10. Findings: Messages were predominantly about the location, the course, student experience, credibility and career progression. They are framed in an appealing way, filled with facts and figures, images of beautiful buildings and smiling students, testimonials of facilities and experiences that form a sense of compatibility and belonging. Research limitations/implications: This study provides insights for the higher educational institutions to enhance their future marketing communications strategies in terms of effectively differentiating one university from another by highlighting the predominantly used appeals among 121 prospectuses and the need for adopting a more consistent approach between the clearing period and non-clearing period in terms of designing the prospectuses. This study has considered only the print platform, and therefore future studies should also look at social media and university websites in the context of the integrated marketing communications. Practical implications: Accurate and coherent narratives should be provided, taking into consideration the diverse nature of target audience. Universities need to realise that they can be held responsible for the promises presented in their prospectuses. Using the city appeal by many universities may be challenging, as there is need to attract students not just to the city itself, but to the university's campus. Originality/value: Having a significantly larger sample than any other previous studies in this field, the empirical evidence provided in this paper is rich and in-depth, thanks to the size and age of the sample as well as the integrated and combined methodological approach. Five keys themes with sub-themes, descriptions and examples were provided, suitable for future research in higher education marketing.

- Abstract
The aim of this study is to conduct a situational analysis of the benefits and drawbacks of returning to face-to-face courses in the Leveling Courses of the Universidad de las Fuerzas Armadas ESPE Sede Latacunga during the post-COVID-19 era. This will be done by comparing the virtual study mode in 2022 to the face-to-face mode in 2023. The results of this analysis will assist higher education institutions in creating interventions that promote resilience in students who are transitioning from high school to undergraduate education and reducing dropout rates. The study employs prospective methods that include historical-logical empirical methods and a review of relevant documents. The findings of the study indicate that face-to-face attendance has a positive impact on students' classroom experience. The study also highlights the need for a paradigm shift in higher education based on this experience. The proposed solution involves updating the curricula, embracing the expanded use of information and communication technology (ICT), enhancing students' soft skills, improving pedagogical training, and reinforcing hybridization to provide a defense against constant crises.

- Abstract
This paper seeks to gain insights into teachers' perceptions, and readiness to integrate information and communication technology (ICT) tools in mathematics instruction. A mixed-methods approach was employed, involving surveys and interviews with a sample of high school mathematics teachers. The study involved 90 mathematics teachers working in three senior high schools in Kumasi metropolis in Ghana. The study revealed that teachers generally hold positive perceptions of the benefits of ICT tools in mathematics teaching. They strongly agree that ICT tools enhance students' understanding of mathematical concepts and improve their engagement and motivation in mathematics classes. Teachers also recognize the potential of ICT tools in promoting problem-solving skills and providing opportunities for differentiation and personalized learning. However, opinions regarding student-centered learning, exploration, and creativity through ICT tools were more varied, suggesting a need for further investigation and support in these areas. In addition teachers expressed the need for continuous training on specific tools, curriculum alignment, and assessment methods.

We report herein a facile and generalized approach to the modification of solid surfaces with polymer brushes under ambient conditions: filter paper‐assisted surface‐initiated Cu0‐mediated controlled radical polymerization (PSI‐CuCRP). The polymerization solution wetted filter paper is sandwiched between a copper plate and an initiator‐modified substrate, which allows the creation of a surface‐initiated polymerization (SIP) “band‐aid” so that everyone can perform the surface grafting selectively with good control over the quality of the polymer brushes employing low concentration and microliter amounts of the monomer solution. The versatility of this method is demonstrated by grafting different homo‐, block‐, and multicomponent polymer brushes by using the same activation system and reaction conditions, the polymerization process can be precisely controlled to yield uniform polymers and show high chain‐end functionality which is exemplified by in situ tetra‐copolymerization. The combination of photolithography and paper cutting enables to prepare arbitrary three‐dimensional patterned polymer brushes on the surface., A facile and generalized approach is reported for the modification of solid surfaces with polymer brushes under ambient conditions: filter paper‐assisted surface‐initiated Cu0‐mediated controlled radical polymerization. A surface‐initiated “band‐aid” of the monomer solution wetted filter paper covered with a thin copper plate allows to perform the surface grafting selectively with polymer brushes.

This work reports on fully integrated “sample‐in‐signal‐out” microfluidic paper‐based analytical devices (μPADs) relying on bioluminescence resonance energy transfer (BRET) switches for analyte recognition and colorimetric signal generation. The devices use BRET‐based antibody sensing proteins integrated into vertically assembled layers of functionalized paper, and their design enables sample volume‐independent and fully reagent‐free operation, including on‐device blood plasma separation. User operation is limited to the application of a single drop (20–30 μL) of sample (serum, whole blood) and the acquisition of a photograph 20 min after sample introduction, with no requirement for precise pipetting, liquid handling, or analytical equipment except for a camera. Simultaneous detection of three different antibodies (anti‐HIV1, anti‐HA, and anti‐DEN1) in whole blood was achieved. Given its simplicity, this type of device is ideally suited for user‐friendly point‐of‐care testing in low‐resource environments.

Halide perovskite quantum dots (PQDs) are promising materials for diverse applications including displays, light‐emitting diodes, and solar cells due to their intriguing properties such as tunable bandgap, high photoluminescence quantum yield, high absorbance, and narrow emission peaks. Despite the prosperous achievements over the past several years, PQDs face severe challenges in terms of stability under different circumstances. Currently, researchers have overcome part of the stability problem, making PQDs sustainable in water, oxygen, and polar solvents for long‐term use. However, halide PQDs are easily degraded under continuous irradiation, which significantly limits their potential for conventional applications. In this study, an oleic acid/oleylamine (traditional surface ligands)‐free method to fabricate perovskite quantum dot papers (PQDP) is developed by adding cellulose nanocrystals as long‐chain binding ligands that stabilize the PQD structure. As a result, the relative photoluminescence intensity of PQDP remains over ≈90% under continuous ultraviolet (UV, 16 W) irradiation for 2 months, showing negligible photodegradation. This proposed method paves the way for the fabrication of ultrastable PQDs and the future development of related applications., Solid‐state perovskite quantum dot papers are fabricated using a unique vacuum filtration growth method without a purification process. The bonding between cellulose nanocrystals and perovskite quantum dots makes the hybrid structure stable, and record high UV stability and thermal stability are achieved for perovskite quantum dot papers.

Soengas-Pérez, Xosé, Rodríguez-Castro, Marta, and Campos-Freire, Francisco
- Abstract
The audiences of generalist television's newscasts reflect that the viewers' interests and loyalties are constantly changing. Research shows that several elements influence the success of programs and formats, but in this paper, we draw attention to the factors that determine the credibility of newscasts. We also want to know how pluralism is safeguarded in newscasts, as we consider that credibility and pluralism are two intertwined values that influence one another. As credibility is a subjective value, it is required to find new information criteria that is suitable and of the utmost rigor. The main aim is to delve into whether there is a consensus on the basic parameters for the definition, identification, and assessment of credibility of nationwide public service media in Spain. Moreover, we are also interested in whether audience figures can be used to determine the degree of trust of newscasts. The analysis brings forward the observations of researchers, scholars and media professionals that offer a vision on the different approaches that integrate the multiple aspects affecting news consumption and interpretation. We conclude that credibility is a concept composed of multidimensional components, resulting from a process where different filters condition fact perception. That is why a story can have different meanings, related to the different point of views of citizens.

Following the fast spread of the coronavirus (Covid-19) across Europe and North America in March 2020, many people started stockpiling commodities like toilet paper. Despite the high relevance for public authorities to adequately address stockpiling behavior, empirical studies on the psychological underpinnings of toilet paper stockpiling are still scarce. In this study, we investigated the relation between personality traits, perceived threat of Covid-19, and stockpiling of toilet paper in an online survey (N = 996) across 22 countries. Results suggest that people who felt more threatened by Covid-19 stockpiled more toilet paper. Further, a predisposition towards Emotionality predicted the perceived threat of Covid-19 and affected stockpiling behavior indirectly. Finally, Conscientiousness was related to toilet paper stockpiling, such that individuals higher in Conscientiousness tended to stockpile more toilet paper. These results emphasize the importance of clear communication by public authorities acknowledging anxiety and, at the same time, transmitting a sense of control.

Rimanelli, Marco and Gurba, Krzysztof
- Abstract
Among recent e-Learning Pedagogical Strategies, gaming and crisis-simulation games are increasingly used in recent years in university-learning and Blended-courses as an out-of-context effective tool for role-playing and education, especially in Law Schools and Business Schools. Gaming covers several sub-fields (war-games; Law School Mock-Trials; Tailor-made educational games in Business; playing commercials-off-the-shelf games; programming and code-learning; games to promote social inclusion of marginalized groups; Model U.N. and crisis-simulations) and are recently enhanced by the impact of using multi-modality and on-line education to apply several concurrent modes of presentation/communications, which are now being applied also in Political Sciences and Communications courses. In recent years, the much-touted future role of the Net-Generation of children and youth who grew-up with computer games should find a natural educational outlet in gaming, but this has been limited to the entertainment field, rather than university education, or in computer coding and programming, where gaming (both on-line and face-to-face) has only marginal effects, due to students' inability to grasp theoretical concepts, poor preparation or poor motivation. Thus, despite already existing methods of gamification in education, its promise as a didactic method in schools and universities is still at its beginnings. This paper analyzes as case-studies the emerging impact of gaming simulations in Political Sciences Blended-courses at Saint Leo University, USA and in Communications courses at the Pedagogical University of Kraków, Poland.

H. Koga, N. Namba, T. Takahashi, M. Nogi, Y. Nishina. Renewable Wood Pulp Paper Reactor with Hierarchical Micro/Nanopores for Continuous‐Flow Nanocatalysis. ChemSusChem 2017, 10, 2560. https://doi.org/10.1002/cssc.201700576., Continuous-flow nanocatalysis based on metal nanoparticle catalyst-anchored flow reactors has recently provided an excellent platform for effective chemical manufacturing. However, there has been limited progress in porous structure design and recycling systems for metal nanoparticle-anchored flow reactors to create more efficient and sustainable catalytic processes. In this study, traditional paper is used for a highly efficient, recyclable, and even renewable flow reactor by tailoring the ultrastructures of wood pulp. The “paper reactor” offers hierarchically interconnected micro- and nanoscale pores, which can act as convective-flow and rapid-diffusion channels, respectively, for efficient access of reactants to metal nanoparticle catalysts. In continuous-flow, aqueous, room-temperature catalytic reduction of 4-nitrophenol to 4-aminophenol, a gold nanoparticle (AuNP)-anchored paper reactor with hierarchical micro/nanopores provided higher reaction efficiency than state-of-the-art AuNP-anchored flow reactors. Inspired by traditional paper materials, successful recycling and renewal of AuNP-anchored paper reactors were also demonstrated while high reaction efficiency was maintained.

31. Smoke and Mirrors: 2021 Garth Boomer Address and Reflection

- Abstract
The power of the coloniser within colonial Australia is clear when we consider how central to the teaching and learning and schooling in Australia is the privileging of Standard Australian English. Prior to 1788, the peoples and the lands of this country were abound with languages. That was until the coloniser exerted their power and insisted on a supposedly monolingual society despite being an amalgamation of various Englishes. Quintessential to maintaining the status quo and assumed power of the coloniser is subject English. I want to query the privileged positioning of subject English and its role in privileging the dominant norm. The subject content, the privileging of the coloniser's language, the silencing of Indigenous voices, even the naming of the subject -- all work to maintain the status quo. In a world where technology auto-corrects and predicts our writings, where 'new' ways of communicating such as emojis are becoming prevalent, where the written word is reduced to memos, text messages and emails, where the evolution of language is studied and yet, the consistent message is that you must excel in Standard Australian English. There has never been a 'pure' English nor a standard Australian English in colonial Australia. Our curriculum makes this explicit when we ask students to explore the evolution of language. In this paper, I share the script from my Garth Boomer address provided in 2021 where I wanted to extend the provocation, I raised in 2019 -- why is Standard Australian English the only means of communication privileged in the Australian Curriculum? And be so bold to ask: could (or should) subject English be renamed? Why not Languages, literacy and communication as found in the Welsh Curriculum or how about, simply, Language Arts?

- Abstract
Conflicts based on race and ethnicity have been documented in CSD programs. The purpose of this paper is to discuss a racially based conflict that occurred in a speech-language pathology graduate program at a Historically Black University and how the program director, the university's chief diversity officer, the program faculty, and students worked together to address it. The paper discusses, in detail, the racially based conflict and the specific steps that the program took to address the conflict and to maintain a racially inclusive atmosphere in the program. Details of five specific activities that were used are discussed. The paper concludes with ten suggestions for other programs who may experience racially based conflicts among students.

Lauren Trejo and Sarah M. Ginsberg
- Abstract
This qualitive study examined four communication sciences and disorders (CSD) graduate students' experiences with feedback from CSD faculty members to understand how it affected their relationships with faculty. Review of the literature revealed the importance and impact of feedback; however, it offered little research examining feedback within the field of CSD. Graduate CSD students who completed their undergraduate degrees in CSD were interviewed to reflect on feedback experiences they received from faculty during their undergraduate and graduate education. The students were also presented with two mock papers with differing feedback styles and were asked their reactions to the feedback. It was discovered that feedback received directly contributed to faculty's overall perceived approachability, with more imbalanced critical feedback increasing the perception of unapproachability towards faculty members. Additionally, the feedback modality, language used, and balance of positive and negative comments strongly influenced participant's perception of the feedback being given as an inherently pleasant or unpleasant.

We demonstrate, for the first time, the multiplexed determination of microbial species from whole blood using the paper‐folding technique of origami to enable the sequential steps of DNA extraction, loop‐mediated isothermal amplification (LAMP), and array‐based fluorescence detection. A low‐cost handheld flashlight reveals the presence of the final DNA amplicon to the naked eye, providing a “sample‐to‐answer” diagnosis from a finger‐prick volume of human blood, within 45 min, with minimal user intervention. To demonstrate the method, we showed the identification of three species of Plasmodium, analyzing 80 patient samples benchmarked against the gold‐standard polymerase chain reaction (PCR) assay in an operator‐blinded study. We also show that the test retains its diagnostic accuracy when using stored or fixed reference samples.

Drew T. Ashby-King, Melissa A. Lucas, and Lindsey B. Anderson
- Abstract
Feedback is a foundational communicative aspect of the teaching/learning processes in introductory communication courses as students seek to improve their presentational speaking skills throughout the term. Drawing on 1,673 qualitative questionnaire responses, this paper explores how students used and interpreted instructor feedback. Through our thematic analysis of a randomly selected subset of 335 responses, we identified two tensions in how students used and interpreted instructor feedback: (1) feedback as a process vs. a product and (2) feedback as integrated into the course structure vs. a justification for a grade. Theoretically, this research extends Feedback Intervention Theory by highlighting the importance and nuance of this communicative process in educational settings. Pedagogically, our findings emphasize the need for discursive opportunities that facilitate the co-construction of meaning surrounding the feedback provided in the introductory communication course.

- Abstract
Feedback is identified in the works of researchers as an essential element for improving the learning process of students. Research shows that lecturer's feedback creates value when it provides not only appraisal information but also links to further learning. This type of feedback affects the learner's information behaviour, i.e., encourages searching for additional information and using it in the learning process. The paper aims to analyze the peculiarities of students' information behaviour during feedback. The research object is investigated from an information science perspective, using theories of information behaviour. An exploratory quantitative survey of 111 Communication BA students from Vilnius University, Lithuania, was conducted. The results of the study revealed the characteristics of feedback inspired by information behaviour: the feedback provided by the lecture is the primary source of information; feedback promotes individual information search; timely feedback encourages proactive information behaviour.

Way Kiat Bong and Weiqin Chen
- Abstract
The use of information and communications technology (ICT) in higher education institutions has increased in the past 20 years. While ICT has brought many benefits to students and faculty, research shows that it also creates barriers and challenges for students with disabilities due to the inaccessibility of digital tools and learning materials. Faculty members play an important role in inclusive higher education. Previous studies have emphasised the need to train faculty about digital accessibility to achieve inclusion in higher education. This systematic literature review aims to study existing work on increasing the faculty members' competence in providing accessible and inclusive digital learning materials and environments to students in higher education. Sixteen peer-reviewed papers were included and analysed. Most trainings included topics on disability and awareness, legislation, and methods of producing accessible digital materials and providing inclusive digital learning environments. While surveys and interviews were mostly used to evaluate training outcomes, there was a lack of objective data and commonly accepted instrument for evaluation. Good practices and further research opportunities are identified. This study has implications for researchers and higher education institutions that are interested in research and practice on increasing general competence in digital accessibility and inclusive education.

40. The Notion of 'Information' in Genetics: A Pragmatic Model
- Author

Martina Blecic
- Abstract
In this paper I suggest a pragmatic model for the notion of 'information' used in molecular biology in the description of protein synthesis. Discarding any ontological commitments of the term 'information', I propose a view of information based on an analogy with communication. This view could at least supplement the existing information-metaphor that should be updated for two reasons: (i) the concept of information it presupposes, and (ii) the origin of the metaphor itself. Besides, the metaphorical nature of the notion of 'information' is still often overlooked, which leads to a false sense of understanding of the underlying genetic phenomena it should describe. The advantages of a model based on communication, as it is seen by the field of pragmatics, is twofold: (i) it provides a rather simple analogy between human communication and basic genetic processes, and (ii) it supplies the tools for the understanding of the non-literal use of the term 'information'.

- Abstract
The shift from specialised studio environments to standardized classroom learning has changed the shape of Communication Design education today. As networked learning and augmented digital classrooms continue to dominate higher education, the purpose of this paper is to examine the impact of a repertoire of learning spaces on students' engagement within contemporary Communication Design studio learning. This study proposes educators and learning space coordinators employ a methodological framework, known as a Methods Process Model (MPM), to empower students to form their own strategies for learning in conventional studio and generic classroom spaces. This paper discusses the findings from two case studies in the UK and Australia.

- Abstract
The purpose of this paper is to describe the influence of political knowledge on the political behavior of highly educated Muslim society in addressing political issues. This research used cohort-based quantitative method through data collection, interviews, and documentation. To collect information from respondents, this research used questionnaire to reveal their political knowledge levels and behaviors. Interviews towards respondents were also conducted to directly confirm the information in the questionnaire. This paper presents information that highly educated Muslims cannot always be invited to dialogue-based solely on political knowledge in understanding and responding to political issues but must be invited to understand through thinking channels outside of knowledge. There is another dimension that shapes the political attitudes of highly educated Muslims in Indonesia, in this case, the religious doctrine which is more dominant than knowledge. Thus, knowledge is not the main factor in controlling people's actions and attitudes, but only a small part of the accumulation of factors.

With the rapid development of information technology, scientific social networks (SSNs) have become the fastest and most convenient way for researchers to communicate with each other. Many published papers are shared via SSNs every day, resulting in the problem of information overload. How to appropriately recommend personalized and highly valuable papers for researchers is becoming more urgent. However, when recommending papers in SSNs, only a small amount of positive instances are available, leaving a vast amount of unlabelled data, in which negative instances and potential unseen positive instances are mixed together, which naturally belongs to One-Class Collaborative Filtering (OCCF) problem. Therefore, considering the extreme data imbalance and data sparsity of this OCCF problem, a hybrid approach of Social and Content aware One-class Recommendation of Papers in SSNs, termed SCORP, is proposed in this study. Unlike previous approaches recommended to address the OCCF problem, social information, which has been proved playing a significant role in performing recommendations in many domains, is applied in both the profiling of content-based filtering and the collaborative filtering to achieve superior recommendations. To verify the effectiveness of the proposed SCORP approach, a real-life dataset from CiteULike was employed. The experimental results demonstrate that the proposed approach is superior to all of the compared approaches, thus providing a more effective method for recommending papers in SSNs.

Advanced carbon materials are important for the next-generation of energy storage apparatus, such as electrochemical capacitors. Here, the physical and electrochemical properties of carbonised filter paper (FP) were investigated. FP is comprised of pure cellulose and is a standardised material. After carbonisation at temperatures ranging from 600 to 1700 °C, FP was contaminant-free, containing only carbon and some oxygenated species, and its primary fibre structure was retained (diameter ≈20–40 μm). The observed enhancement in conductivity of the carbonised FP was correlated with the carbonisation temperature. Electrochemical capacitance in the range of ≈1.8–117 F g−1 was achieved, with FP carbonised at 1500 °C showing the best performance. This high capacitance was stable with >87 % retained after 3000 charge–discharge cycles. These results show that carbonised FP, without the addition of composite materials, exhibits good supercapacitance performance, which competes well with existing electrodes made of carbon-based materials. Furthermore, given the lower cost and renewable source, cellulose-based materials are the more eco-friendly option for energy storage applications.

- Abstract
This paper is derived from a field study in the framework of my doctoral dissertation, in which we analyze life stories (Bertaux, 2005) of young people who have discontinued their studies at the University of Buenos Aires (UBA) in four courses with a high rate of dropout between the years 2005-2015: Computer Engineering, Anthropological Sciences, Chemical Sciences and Communication Sciences. With that goal in mind, seventy-five interviews were conducted with fifty-nine people: sixteen key informants and forty-three young people who discontinued their university studies between 2005 and 2015. In this paper we present one aspect of the analysis: the reconstruction of the symbolic framework of the discontinuation experience from the perspective of its protagonist, and how this outlines specific types of discontinuation.

Carbonaceous materials, especially with graphite‐layers structure, as anode for potassium‐ion batteries (PIBs), are the footstone for industrialization of PIBs. However, carbonaceous materials with graphite‐layers structure usually suffer from poor cycle life and inferior stability, not to mention freestanding and flexible PIBs. Here, a freestanding and flexible 3D hybrid architecture by introducing carbon dots on the reduced graphene oxide surface (CDs@rGO) is synthesized as high performance PIBs anode. The CDs@rGO paper has efficient electron and ion transfer channels due to its unique structure, thus enhancing reaction kinetics. In addition, the CDs provide abundant defects and oxygen‐containing functional groups, which can improve the electrochemical performance. This freestanding and flexible anode exhibits the high capacity of 310 mAh g−1 at 100 mA g−1, ultra‐long cycle life (840 cycles with a capacity of 244 mAh g−1 at 200 mA g−1), and excellent rate performance (undergo six consecutive currents changing from 100 to 500 mA g−1, high capacity 185 mAh g−1 at 500 mA g−1), outperforming many existing carbonaceous PIB anodes. The results may provide a starting point for high‐performance freestanding and flexible PIBs and promote the rapid development of next‐generation flexible batteries., A freestanding and flexible 3D hybrid architecture by introducing carbon dots on the reduced graphene oxide surface is synthesized as a high‐performance potassium‐ion battery anode. It may provide a starting point for high‐performance freestanding and flexible potassium‐ion battery and promote the rapid development of next‐generation flexible batteries.
