Synthesis of Bi4O5I2 coupled with Sb2WO6 boosts the photocatalytic degradation of tetracyclines under simulated sunlight

For this study, a Sb2WO6/Bi4O5I2 composite material was successfully prepared via a precipitation-calcination method. The Sb2WO6/Bi4O5I2 heterostructure enhanced the light absorption and facilitated the separation of charge carriers. Under simulated sunlight exposure, the removal rates of tetracycline (TC) and doxycycline hyclate (DOX·HCl) reached 88.2% and 83.9%, respectively, over an optimized SWB2 composite (theoretical mole ratio of Sb2WO6: BiOI was 1.5:10). Further, the total organic carbon (TOC) removal rates were 37.6% and 33.7%, respectively. The experiments explored various parameters including catalyst dosage, initial concentrations of TC and DOX·HCl, solution pH, and common inorganic ions. The TC and DOX·HCl degradation pathways were speculated. Furthermore, SWB2 demonstrated remarkable stability and cyclability under simulated sunlight. Trapping experiments and electron paramagnetic resonance (EPR) tests revealed that •O2- played a major role as a free radical in the photocatalytic process, while h+ and •OH also had significant contributions. Based on in-situ XPS, trapping experiments, EPR test, band bending analysis, and SPV tests, the formation of S-scheme heterojunction between Sb2WO6 and Bi4O5I2 was inferred. This study provides insights into the design strategy of S-scheme heterojunctions between Aurivillius-type compounds and bismuth-rich halide bismuth oxide, which is informative for the development of advanced environmental remediation concepts.

‘If I Do Not Satisfy My Present Inclination in Writing, It is Very Probable I May Haunt you’: Astral Projection in Bluestocking Letters (1740–1770)

ABSTRACT This article examines the concept of ‘astral projection’ in the letters of the Bluestocking intellectuals Elizabeth Montagu (1718–1800), Elizabeth Carter (1717–1806), and Catherine Talbot (1721–1770). By this term, I am referring to episodes in their correspondence in which they imaginatively project themselves into the physical presence of the letter’s reader, or deploy images of death and haunting to poetically bridge social distance. Exploring this concept through the frameworks of Susan Lanser’s engagement with Bluestocking Queerness, as well as the concept of material remediation of affect drawn from Sarah Ahmed and others, I would like to address this technique as a device for the affective bridging of distance, as well as exploring the central case study of Elizabeth Montagu’s use of astral projection in her letters to Scottish Enlightenment philosopher, Henry Home, Lord Kames, in which astral projection is utilised to bridge not just physical distance, but the barriers of social status, and Montagu’s own outsider status from Scottish Enlightenment philosophical circles. Ultimately, I argue that astral projection acts as a synecdoche for the familiar letter as a uniquely transformative textual space, in which meanings of all kinds are renegotiated and redefined, including the meaning of distance and separation.

Remediation of Heavy Metal Pollution in Soil by Biochar

Soil is an important resource for human survival and life, but with the economy and society developing, industrial pollution, agricultural chemicals, domestic sewage, and so on have entered the soil, causing serious soil heavy metal pollution. Soil pollution has concealment and hysteresis. Pollutants in soil are not easy to diffuse and dilute as in water and atmosphere, so they are easy to accumulate in soil and exceed the standard. Due to the demand for environmental protection, the restoration of soil is imminent. Under anoxic conditions, the solid material of the raw material after high-temperature pyrolysis is biochar. It is a soil improvement and adsorption material with high porosity and strong adsorption capacity, so it is widely used in soil remediation of heavy metal pollution. The essential concepts of biochar remediation of soil heavy metal pollution and the factors influencing biochar remediation of heavy metal polluted soil are therefore reviewed in this work and this paper also expounds on the advantages of biochar compared with other remediation methods such as phytoremediation and physical remediation.

Soil-Water Comprehensive Treatment Theory of Urban Fringe

Urban fringe is an active expanding belt, the environment of the urban fringe is complex and frangible. Previous studies have focused on the landscape spatial pattern changes, the spatial-temporal variability of soil pollutants and the land management and policy issues, etc., but it is lack of the theory and practice study of land & water comprehensive remediation in urban fringe areas. This article is taking the Shichuan River as an example. And establish a new concept of comprehensive remediation with soil purification as the key, and with water treatment as the link, meanwhile it will keep clear water with pure land. Form land organic rearrangement theory for different types of land utilization.

“No one believes we dated” - lesbian YouTube as a tool for Rhetorical Citizenship

ABSTRACT This paper investigates how lesbians utilize YouTube to make themselves into rhetorical citizens and how YouTubers use hypermediation and mediated authenticity to achieve an authentic sense of a virtual community among the lesbian minority group. I review the concepts of rhetorical citizenship, mediated authenticity and remediation. Furthermore, I analyze two videos by lesbian YouTubers, focusing on the stylistic features while applying the theory of mediated authenticity. The paper concludes that, through the platform of YouTube, some lesbians have the opportunity to acquire rhetorical agency—and become rhetorical citizens through participation in democracy. Through the use of authenticity puzzles, the lesbian YouTubers manage to create a sense of community and encourage lesbian viewers to actively participate—and unite them in shared experiences they can relate to such as shared cultural codes. Although lesbian YouTubers today play a big part in giving lesbians representation and reducing minority stress, there is a long way to go before lesbians have achieved the diverse representation they need to attain access to rhetorical citizenship through the platform of YouTube. Until BIPOC lesbians get more visibility, one will not be able to claim that lesbians have gained the full potential of rhetorical citizenship through YouTube.

Addressing human rights abuses at mega-sporting events-A shared responsibility in theory and practice.

Mega-sporting events (MSEs) have great potential to promote human rights and be a force for good, not only in the host country or city where the event takes place, but also beyond. At the same time, these events are regularly linked to human rights abuses and this opinion piece provides an overview of MSE-related adverse human rights impacts and discusses how the governance of these events enables these impacts to occur in the context of bidding for, preparing, and delivering these events. At the core of this discussion the paper presents a shared responsibility approach and argues that if applied in a preventative and retrospective way and including the concept of collaborative remedy, it can help address these adverse impacts. This is followed by a reflection on the feasibility of this approach, by considering to what extent current developments in the evolving sport and human rights movement are going in that direction and the paper finishes with a brief discussion on the importance of making the current changes sustainable and how research and education are key elements of this endeavour.

Video Art in the Southern Cone. Festivals, archives, and remediation of the analogue past

This article examines the challenges faced by physical and digital archives dedicated to video art in the Southern Cone, focusing on accessibility, preservation, and dissemination. To map such a complex situation, firstly, it identifies four influential Latin American video art festivals, including the Festival Franco-Chileno de Video Arte, the Festival Franco-Latinoamericano de Video Arte, Videobrasil and Buenos Aires Video, which promoted the production, circulation, and dissemination of audiovisual arts in the last two decades of the 20th century. Secondly, the article explores three regional initiatives – UMATIC, Açervo online Associação Cultural Videobrasil, and ARCA – that, since the mid-2000s, have carried out tasks of valuation and making accessible video art collections related to the aforementioned festivals. Drawing on Bolter and Grusin’s concept of remediation, it is proposed that these three initiatives be interpreted as remediation projects, as they are concerned with reshaping old media formats and multiplying media through hypermediation. The understanding of these projects also relies on the concept of “anomic archive”, which refers to the idea of a documentary archive constructed through an intentional process of collecting and sharing knowledge beyond traditional institutions. Finally, the article approaches digital archives as a means of accessing primary sources, proposing a reflection on the opportunities and risks posed by these remediation projects.

Scrolling back: Remediation within and through digital memory work

Abstract This article explores how the concept of remediation is part of digital memory work performed by young women on Instagram. While remediation has been used to make sense of the ways sites of memory are represented across time and through different media, mnemonic media practices and forms are remediated in digital memory work. This article draws on interviews, observations of Instagram activities, and focus group data to analyse how other media practices and forms are integrated into digital memory work on Instagram and mobilised by young women to make sense of their mnemonic use of the platform. The analysis focuses on how practices of digital memory work use direct remediation of material objects and remediation of the functionality of mnemonic media practices. It addresses how the comparisons participants make to other mnemonic media practices reveal how digital memory work involves negotiation of personal and public, private and professional, and the authentic and staged. In addition, it grapples with the way that sharing happy experiences and moments to produce a ‘highlight reel’ or ‘hall of fame’ in postfeminist digital culture has valuable and potentially harmful implications.

Research Progress and Prospects of Spinel Ferrite Nanostructures for the Removal of Nitroaromatics from Wastewater

Spinel ferrite nanostructures have played significant roles in the development of materials science and technology. Spinel ferrite nanostructures possess not only promising magnetic properties but also high resistivity, stability, and low eddy current losses. The recent progress in the utilization of spinel ferrite nanostructures for water remediation is reviewed with special emphasis on the adsorption, transformation, degradation, and catalytic reduction of nitroaromatics. Then, the structure–property relationships and design considerations of spinel ferrite nanostructures for catalytic applications are discussed in detail. Insights into the details of the various removal processes on the model spinel ferrite nanostructures are provided with a basic concept of nitroaromatics remediation. Subsequently, reaction kinetics and mechanisms are classified and their advantages and disadvantages are described. Lastly, challenges and future perspectives of spinel ferrite nanostructures for their practical applications are presented. With further advancement, spinel ferrites have potential to be practically utilized for a wide range of applications such as water treatment plants.

Coupled microscale zero valent iron-autotrophic hydrogen bacteria dechlorination system is not always superior to its standalone counterparts: A sustainable remediation perspective

The coupling of microscale zero-valent iron with autotrophic hydrogen bacteria (mZVI-AHB) are often believed to show greater potential than the single abiotic or biotic systems in remediating chlorinated aliphatic hydrocarbon-contaminated groundwater. However, our understanding of the remediation performance of this system under real field conditions, especially by incorporating the concept of sustainable remediation, remains limited. In this study, the performances of the mZVI, H2-AHB, and mZVI-AHB systems in dechlorinating groundwater containing complex electron acceptors were compared by evaluating their removal efficiency (RE), reaction products, and electron efficiency (EE), using trichloroethylene (TCE) as the target contaminant and NO3− and SO42− as the coexisting natural electron acceptors. Ultimately, which of these systems had TCE removal superiority was dependent on the coexisting electron acceptor. mZVI-AHB and mZVI resulted in more complete dechlorination, whereas H2-AHB exhibited higher N2 selectivity in reducing NO3−. Regardless of the coexisting electron acceptor, the mZVI-alone system showed the highest EE. Finally, the sustainability concerns and applicability of the three systems were evaluated on the basis of their TCE RE, complete dechlorination ratio, N2 selectivity, EE, and cost, which were integrated into a comparison of overall benefits. Our findings provide comprehensive and insightful information on the factors that determine remediation scheme selection in real practice.

Great Patriotic War in Soviet and Post-Soviet Cinematography: Problems of Remediation

The article is devoted to the representations of the Great Patriotic War in Soviet and postSoviet cinematography. The study presents the comparative analysis of the heroic narrative dating back to wartime propaganda and most clearly manifested in post-war film epics, as well as the tragic narrative, which is inextricably linked with the ‘lieutenant’ prose of the Thaw-era. The changes in the images of the Soviet cinema in the Russian war films of the 2000s are considered. It is proved that these changes, found in modern series and remakes, are critically evaluated by both academic circles and youth audience. On the basis of discussions held in ten focus groups the main critical attitudes are analyzed. Particular attention is paid to the problem of remediation which consists in the predominance of visual images only outwardly copying popular Soviet films, without independent reflection on the specificity and the meaning of military experience. It is noted that the concept of remediation makes it possible to shift the focus from dissatisfaction with individual parts of films about the Great Patriotic War to the general problem of changing the media regime in modern society and to start analyzing the mechanisms of its functioning.

Remediar la cultura impresa: reacciones a la revolución digital en Facsímil (2014), El sistema del tacto (2018), Scout (2016) y Leñador (2013)

The aim of this article is to read four works from the recent Chilean literary field as a series of reflections on print culture. These novels start from the premise that print has been profoundly affected by the digital revolution. In the first part of the article, I develop a theoretical model to understand the effect of digital on print based on the concepts of remediation, materiality, and practices of print culture. I propose that the digital revolution produced a liberation and tension in the printed culture that the four novels I study reflect, and they do so from the questioning of the functions that print has historically had. Facsímil (2014), El sistema del tacto (2018), Scout and Leñador, are novels aware of their status as a physical object, and therefore use their materiality to reflect, intervene and comment on the role printed book plays in the contemporary world. The article seeks to show that printed culture in Chile is in a moment of paradigmatic change and that literature is an exceptional starting point to understand it.

Orchestrated Action of AMPK Activation and Combined VEGF/PD-1 Blockade with Lipid Metabolic Tunning as Multi-Target Therapeutics against Ovarian Cancers.

Ovarian cancer is one of the most lethal gynecological malignancies worldwide, and chemoresistance is a critical obstacle in the clinical management of the disease. Recent studies have suggested that exploiting cancer cell metabolism by applying AMP-activated protein kinase (AMPK)-activating agents and distinctive adjuvant targeted therapies can be a plausible alternative approach in cancer treatment. Therefore, the perspectives about the combination of AMPK activators together with VEGF/PD-1 blockade as a dual-targeted therapy against ovarian cancer were discussed herein. Additionally, ferroptosis, a non-apoptotic regulated cell death triggered by the availability of redox-active iron, have been proposed to be governed by multiple layers of metabolic signalings and can be synergized with immunotherapies. To this end, ferroptosis initiating therapies (FITs) and metabolic rewiring and immunotherapeutic approaches may have substantial clinical potential in combating ovarian cancer development and progression. It is hoped that the viewpoints deliberated in this review would accelerate the translation of remedial concepts into clinical trials and improve the effectiveness of ovarian cancer treatment.

Changing the ownership of ideas: Multimedial accomplishment of collaborative reflection in an organizational workshop

Reflecting on work processes together with one's co-workers is becoming increasingly important in workplaces. This study examined collaborative reflection in the organizational context through analyzing a case of a complex workplace setting where an enterprise social media platform, talk-in-interaction, and handwriting were used to engage participants in the process of reflection. Drawing on the concept of remediation, the results show that collaborative reflection is interactionally accomplished through a multimedial activity chain, in which the ownership of presented ideas is transformed from individual ideas into shared views of the team. The study shows in detail how the process of collaborative reflection evolves in workshop activities and how both traditional and digital media are used to support the process.

Dual-wastes derived biochar with tailored surface features for highly efficient p-nitrophenol adsorption

In line with the concept of green sustainable development and efficient wastewater remediation, it is urgent to fabricate biochar-based sorbents with high-efficiency for pollutant removal. Herein, mixed bio-waste of shrimp shell and rice husk was simultaneously employed to prepare composite biochar with enriched surface functional groups for p-nitrophenol adsorption. Batch experiments were conducted to study the adsorption performance under different conditions, by which excellent adsorption capacity in a wide pH range (3–10) was revealed. The pseudo-second-order kinetic model was suitable for p-nitrophenol sorption kinetic, and the maximum sorption capacity of 636.42 mg/g based on the Langmuir isotherm model could be achieved. The main adsorption mechanisms of p-nitrophenol on biochar were the adsorption (chemisorption and physical adsorption) and pore-filling. By virtue of tailored surface chemistry features and high-efficiency, the composite biochar prepared from shrimp shell and rice husk might be a potential candidate for water body remediation via adsorption process.

List of relevant sustainability indicators in remediation processes and their validation by stakeholders

Sustainable remediation designed to assess the environmental, social, and economic impacts and benefits of remediation processes is increasingly being recognized in the traditional management of contaminated sites. However, there are difficulties with some aspects of its design in terms of practical implementation. Therefore, this study aimed to develop a complete list of indicators for sustainable remediation and to validate these indicators with different stakeholders. We selected and categorized 63 sustainable remediation indicators based on a systematic literature review and surveyed experts around the world via email to validate them. The participating experts were characterized according to their country of origin to analyze the relationships in the obtained validations. Based on the perceptions of these experts, the list of indicators was rearranged, considering in addition to the traditional sustainability tripod, also the categories of integration. In addition, the weighting for all indicators was determined using the Likert scoring scale and average ranking. The results indicated the comprehensive knowledge of the research participants about the concepts of sustainable remediation. There was also a greater importance given to environmental and social indicators than economic ones, but the difference was not significant, indicating that we are closer to achieving a balance between the dimensions of sustainability. However, it can be said that there is a big concern with respect to social issues, as when the hypothetical scenarios of contaminated sites to be remedied were analyzed, Scenario 1, which involves a site located in an urban center surrounded by a large population, obtained the highest number of indicators with the highest scores. It can therefore be concluded that this study provides an extensive list of validated indicators, categorized and weighted, that is ready to be used in the context of sustainable remediation, thus reinforcing the discussion about a future standardization of a list of indicators focused on this theme.

Intergenerational struggles and technological dramas of the neobakala music scene

In late modernity, Western societies undergo profound processes of change that lead to tensions between different social actors, which sometimes occur in intergenerational terms. This article explores these tensions in the field of music through the neobakala scene, which is composed of adults who have created a nostalgic discourse to establish a hierarchy with other musical scenes created by youngsters. The concepts of nostalgia and generation, therefore, will be key in articulating this text but both will be critically approximated, since the two assume a presence of memory in their constitution (that is not always backed by evidence). In this sense, this article, which also explores the past of the neobakala scene, claims memory as a field on its own, differentiated from nostalgia and as a source of criticism of it. On the other hand, in the analysis of this nostalgia, the neobakala scene and the same intergenerational struggles that occur in this late modernity, this article will pay special attention to the role of changes. To this end, the article will resort to the concept of remediation and, above all, that of technological drama, which will allow us to observe a process of reintegration in which the neobakala subversive past ends up aligning itself with power in a context of expansion of digital technologies.
