AbstractAll‐solid‐state lithium–sulfur (Li/S) batteries are promising next‐generation energy‐storage devices owing to their high capacities and long cycle lives. The Li2S active material used in the positive electrode has a high theoretical capacity; consequently, nanocomposites composed of Li2S, solid electrolytes, and conductive carbon can be used to fabricate high‐energy‐density batteries. Moreover, the active material should be constructed with both micro‐ and nanoscale ion‐conduction pathways to ensure high power. Herein, a Li2S–Li2O–LiI positive electrode is developed in which the active material is dispersed in an amorphous matrix. Li2S–Li2O–LiI exhibits high charge–discharge capacities and a high specific capacity of 998 mAh g−1 at a 2 C rate and 25 °C. X‐ray photoelectron spectroscopy, X‐ray diffractometry, and transmission electron microscopy observation suggest that Li2O–LiI provides nanoscale ion‐conduction pathways during cycling that activate Li2S and deliver large capacities; it also exhibits an appropriate onset oxidation voltage for high capacity. Furthermore, a cell with a high areal capacity of 10.6 mAh cm–2 is demonstrated to successfully operate at 25 °C using a Li2S–Li2O–LiI positive electrode. This study represents a major step toward the commercialization of all‐solid‐state Li/S batteries.

Published: May 2023

AbstractThe low conductivity of sulfur and the shuttle effect of lithium polysulfides (LiPSs) are the two intrinsic obstacles that limit the application of lithium–sulfur batteries (LSBs). Herein, a sulfur vacancy introduced NiCo2S4 nanosheet array grown on carbon nanofiber (CNF) membrane (NiCo2S4‐x/CNF) is proposed to serve as a self‐supporting and binder‐free interlayer in LSBs. The conductive CNF skeleton with a non‐woven structure can effectively reduce the resistance of the cathode and accommodate volume expansion during charge–discharge process. The bonding between CNF matrix and NiCo2S4 nanosheet is enhanced by in situ growth, ensuring fast electron transfer. Besides, the sulfur vacancies in NiCo2S4 enhance the chemisorption of LiPSs, and the highly active sites at vacancies can accelerate the LiPSs conversion kinetics. LSB paired with NiCo2S4‐x/CNF interlayer achieved improved stability in 500 cycles at 0.2 C and long life of 3000 cycles at 3 C. More importantly, a high areal capacity of 9.69 mAh cm−2 is achieved with a sulfur loading of 10.8 mg cm−2 and a low electrolyte to sulfur (E/S) ratio of 4.8. This work provides insight into the sulfur vacancy in catalysis design for LiPSs conversion and demonstrates a promising direction for electronic defect engineering in material design for LSBs.

Published: May 2023

AbstractReactive oxygen species (ROS)‐mediated biological catalysis involves serial programmed enzymatic reactions and plays an important part against infectious diseases; while the spatiotemporal control of catalytic treatment to break the limitations of the disease microenvironment is challenging. Here, a novel spatiotemporal catalytic microneedles patch (CMSP‐MNs) integrated with dual‐effective Cu2MoS4 (CMS) and polydopamine (PDA) nanoparticles (NPs) for breaking microenvironment restrictions to treat wound infections is designed. Since CMS NPs are loaded in the needles, CMSP‐MNs can catalytically generate diverse ROS to cause effective bacterial inactivation during bacterial infection process. Besides, PDA NPs are encapsulated in the backing layer, which facilitate ROS elimination and oxygen production for solving hypoxic problems in wound microenvironment and alleviating the expression of inflammatory factors during the inflammation process. Based on these features, it is demonstrated through cell and animal experiments that these nanozymes‐integrated MNs patches can realize selective regulation of ROS level with bacterial inactivation and inflammatory treatment, resulting in minimized side effects of over‐production ROS and effective anti‐infected treatment. It is believed that the presented MNs can provide a new therapeutic strategy with spatiotemporal adjustable catalytic properties in biomedical areas.
Tunable Afterglow and Self‐Trapped Exciton Emissions in Zr (IV)‐Based Organic–Inorganic Metal Halide Hybrids by Metal‐Ion Doping

Published: May 2023

AbstractLow‐dimensional hybrid metal halide (LDHMH) materials have attracted considerable attention owing to their intriguing optical properties. To the best of the knowledge, this is the first study to successfully demonstrate both self‐trap exciton (STE) and afterglow emissions in Zr‐based LDHMH materials. The obtained pure (Ph3S)2ZrCl6 crystals showed near‐ultraviolet phosphorescence and a green afterglow owing to the organic cation Ph3S+, while the Bi‐doped and Sb‐doped crystals exhibited both STE and afterglow emissions. However, the Te‐doped crystals showed only a broad yellow STE emission owing to the [TeCl6]2− octahedron. In addition, all the crystals showed good stability. Notably, Sb‐doped crystals produced white light, which can be adjusted between cold white and warm white using different excitations. Finally, this strategy for both STE and afterglow emissions can be applied to other LDHMH materials for optical applications.
Electrochemistry of Titanium Carbide MXenes in Supercapacitor
Authors: Jiang Tingting , Wang Yichen , Chen George Z. 
Published: May 2023

AbstractNovel electrode materials are always explored to achieve better performance of supercapacitors. Titanium carbide MXenes, Ti3C2Tx, are one of the very promising candidates for electrode materials in supercapacitors due to their unique structural and ion storage properties as 2D materials. Their large specific surface area, adjustable functionalized surface terminals, high electrical conductivities, hydrophilicity, and high Faradaic capacitance, also known widely but confusingly as pseudocapacitance, are highly desirable for making high‐performance electrodes with increased dis‐/charging rates and capacities. Herein, some selective electrochemical considerations of Ti3C2Tx MXenes for uses in supercapacitors are critically reviewed and assessed, aiming at a better fundamental understanding of the electrochemical basics and processes in Ti3C2Tx MXene‐based electrode materials for supercapacitor applications.

Published: May 2023

AbstractThe development of new materials for electromagnetic interference (EMI) shielding is an important area of research, as it allows for the creation of more effective and high‐efficient shielding solutions. In this sense, MXenes, a class of 2D transition metal carbides and nitrides have exhibited promising performances as EMI shielding materials. Electric conductivity, low density, and flexibility are some of the properties given by MXene materials, which make them very attractive in the field. Different processing techniques have been employed to produce MXene‐based materials with EMI shielding properties. This review summarizes processes and the role of key parameters like the content of fillers and thickness in the desired EMI shielding performance. It also discusses the determination of power coefficients in defining the EMI shielding mechanism and the concept of green shielding materials, as well as their influence on the real application of a produced material. The review concludes with a summary of current challenges and prospects in the production of MXene materials as EMI shields.

Authors: Béke Ferenc , Csenki János T. , Novák Zoltán 
Published: May 2023

AbstractSynthesis and applications of fluoroalkyl and fluoroalkenyliodonium salts are summarized in this account article, focusing preferably to the reagents designed in our laboratory in the last decade. Among these reagents trifluoroethyl(aryl)iodonium salts have been used most frequently to build carbon‐carbon and carbon‐heteroatom bonds in simple nucleophilic substitutions and through transition metal catalyzed coupling reactions. Iodonium salts equipped with unsaturated fluorinated function showed diverse reactivity due to their electron deficient character, and these molecular motifs enable cycloadditions and nucleophilic additions to prepare fluorinated carbo‐ and heterocyclic molecules. Beyond the overview of existing transformations, with the presented collection, we aim to inspire future developments of iodonium reagents and their application in organic synthesis.

Published: May 2023

AbstractShared book reading is a common and effective way to support vocabulary knowledge. However, it is not the only pedagogy for supporting this learning goal. We propose a “toolbox” of activities that teachers can use to foster vocabulary acquisition in young children. We first discuss the science behind why these activities are effective (they are active, engaging, meaningful, socially interactive, iterative, and joyful), and then give examples of playful learning experiences that have been effectively used in classroom vocabulary interventions. Finally, we offer ways in which these activities can be easily adapted to help educators reach vocabulary‐teaching goals in their own classrooms.

ABSTRACTObjectiveTo review the evidence on the effect of mode of delivery on perinatal outcome of fetuses born before 32 weeks' gestation.MethodsMEDLINE, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), the
ClinicalTrials.gov registry and gray literature sources were searched, starting from the year 2000 to reflect contemporary practice in perinatal care. Non‐randomized or randomized studies that included singleton fetuses without chromosomal abnormality or major congenital defect delivered vaginally or via Cesarean section were eligible for inclusion in the analysis. Primary outcomes were neonatal death, defined as death in the first 28 days of age, and survival to discharge. Secondary outcomes were other adverse perinatal events. The ROBINS‐I tool was used to assess the risk of bias. The overall quality of evidence for the outcomes was assessed according to GRADE. Summary odds ratios (ORs) with 95% CIs were calculated, and random‐effects models were used for data synthesis. Subgroup analysis was performed for delivery before 28 weeks, delivery between 28 and 32 weeks and according to fetal presentation at delivery.ResultsA total of 27 retrospective studies (22 887 neonates) were included in the systematic review and meta‐analysis, all of which reported on singleton pregnancies. Among cases born before 28 weeks, vaginal delivery significantly increased the risk of neonatal death of fetuses with any type of presentation (n = 1496) (OR 1.87 (95% CI, 1.05–3.35); I2 = 65%, very low quality of evidence) and of fetuses with breech presentation (n = 733) (OR 3.55 (95% CI, 2.42–5.21); I2 = 21%, moderate quality of evidence). The odds of survival to discharge were significantly decreased among fetuses with breech presentation delivered before 28 weeks (n = 646) (OR 0.36 (95% CI, 0.24–0.54); I2 = 21%, low quality of evidence). Among breech fetuses born between 28 and 32 weeks, vaginal delivery increased the odds of perinatal death (intrapartum and neonatal) (n = 1581) (OR 3.06 (95% CI, 1.47–6.35); I2 = 0%, high quality of evidence). In non‐cephalic fetuses born between 24 and 32 weeks, vaginal delivery decreased the odds of survival to discharge (n = 1030) (OR 0.28 (95% CI, 0.19–0.40); I2 = 0%, moderate quality of evidence). No significant effect on mortality of mode of delivery was observed in cephalic fetuses at any gestational age.ConclusionsThis systematic review and meta‐analysis suggests that vaginal delivery in severe preterm birth is associated with an increased risk of neonatal and perinatal death in breech fetuses, while no significant association was observed for cephalic fetuses. © 2023 The Authors.

Emerging themes and factors influencing the prices of biotherapeutics
Authors: Gandhi Sonia , Kashiramka Smita , Rathore Anurag S. 
Published: May 2023

AbstractThe high prices of biotherapeutics remain an area of concern for various national and international agencies working toward developing strategies for monitoring, evaluating, and managing the prices of medicines to promote equitable access. This paper deploys a unique study design to identify emerging themes and determine the elements influencing the price of biotherapeutics specifically biosimilars. This review is based on a bibliometric and qualitative synthesis approach to generate a new line of thinking for future studies. The findings enable knowledge assimilation for policy decisions. The results indicate that while the factors like market share, market competition, and pricing policies are extensively explored by researchers, the factors such as innovation capability, product development costs, and local factors like regulatory ecosystem can be further examined as potential influencers of prices. Further, pricing frameworks and regulations designed for generic drugs cannot be replicated to estimate the prices of biotherapeutics. As a result, policymakers must take the necessary actions to construct innovative pricing frameworks for this class of products that are in conformity with national policies, regulations, market dynamics, and economics. Moreover, studies on incentives and profit margins associated with the last‐mile delivery and accessibility of high‐cost biotherapeutics are essential for their efficient adoption.
From Unheard to Meaningful: When Music Takes Over in Film
Authors: Windisch Anna K. , Tieber Claus , Powrie Phil 
Published: May 2023

AbstractThis introduction lays out the focus of the book on moments in film when ‘unheard melodies’ become heard and meaningful. These filmic instances where music ‘takes over’ and the surreal often becomes the accepted filmic reality are examined in reference to two recent theoretical approaches: ‘musical moments’ (Amy Herzog) and ‘crystal songs’ (Phil Powrie). Divided up into four parts, the book’s chapters apply these two differing but overlapping theoretical concepts to their case studies and discussions. What the Musical Moment Can Do—Theoretical Approaches covers the books’ theoretical foundation by Herzog and Powrie themselves. Part two, How the Musical Moment was Created—Musical Numbers in Silent and Early Sound Cinema, discusses the history of musical numbers from silent to early sound cinema. Then, Musical Dis/Placements—Musical Moments in Global Cinema focuses on the varied manifestations of musical numbers through case studies of different national cinemas. And finally, From Romance to Dystopia looks at the social and political dimensions of musical moments embedded in contemporary cinema, with the goal of evoking further discussions of this rich and foundational filmic element.
Can You Hear the Love Tonight? Creating Cinematic Romance with Diegetic Songs
Authors: Hettich Katja 
Published: May 2023

AbstractThis chapter argues that ‘romance’ as a film genre is best conceived of as an affective experience provided not only by narrative but also by stylistic means. Against this background, it explores a particular type of musical moment in non-musical films: scenes that portray, reflect and shape conceptions of romantic love and create various forms of cinematic romance through the diegetic use of popular songs. Drawing from research on the physical and psychological effects of listening to music, the chapter points out in which aspects songs are placed in a special relationship with romance. Based on the assumption that diegetic song moments can be considered as communicative acts, it proposes starting points for analysing different forms of diegetic song moments. Using examples from films of the last decades, it shows how different narrative set-ups, ways of integrating diegetic songs, performance styles and diegetic audiences influence the shape of cinematic romance.
Musical Moments as Narrative and Emotional Catalysts in Three Silent Films by Jacques Feyder
Authors: Nasta Dominique 
Published: May 2023

AbstractAs many studies have shown, the link between cinema, psychology and music played an important role both theoretically and practically during the French avant-garde of the 1920s in the work of Delluc, Epstein, Gance, Grémillon or L’Herbier. Jacques Feyder’s three films for the Franco-Russian production company Albatros—Visagesd’enfants (1925), Gribiche (1926) and Les Nouveaux Messieurs (1928)—demonstrate his unprecedented mastery of the ‘musical moment’ both in its relationship to stories involving painful situations experienced by young children and in the way it rhythms emotion and affect. Feyder’s mise en scène and spectacular crosscutting techniques crystallise them, yoking the musical moment to a dream, or a mental image, or a simple celebration in a realist pseudo-documentary décor. This chapter elucidates these musical moments using theories related to subliminal auditory perception, deferred time intervals and baseline affective charges: the latter occur in Feyder’s silent films for which no original pre-existing accompaniment is known.
The Afterlife of Continental Romance: Musical Moments in Ichikawa Kon’s Passion Without End (1949) and Fragrance of the Night (1951)
Authors: Yamazaki Junko 
Published: May 2023

AbstractTwo early post-war Japanese films Hateshinaki jōnetsu (Passion without End, 1949) and Ieraishan (Fragrance of the Night, 1951), both directed by Ichikawa Kon, are romantic melodramas featuring popular songs known as ‘continental melodies’ (tairiku merodei) produced by Hattori Ryōichi and performed by transnational celebrity Yamaguchi Yoshiko. The revival of her wartime songs in post-war Japan is often regarded as part of an imperial nostalgia, hence with deep suspicion. However, two of her songs ‘Soshū yakyoku’ (‘Suzhou Serenade’) and ‘Ieraishan’ (‘Fragrance of the Night’), featured in Passion without End and Fragrance of the Night, respectively, form musical moments that highlight the tension between the sensorial appeal of the doomed romance rooted in the imperial past and the disbelief in the sustainability of such romance in early post-war Japan.

Authors: Brouwer Aleid Elizabeth , Mariotti Ilaria 
Published: May 2023

AbstractThe COVID-19 pandemic has accelerated the rise of remote working worldwide and less central areas have become more and more attractive for these workers. Consequently, remote workers started working from home, in new working spaces, and from everywhere. These changes have affected workers’ wellbeing, and cities, peripheral are rural areas. The chapter explores why people decided to keep working remotely even after the pandemic restrictions were cancelled. Furthermore, we give an empirical snapshot of the actual situation of remote workers and how this has and will change geographical patterns. The impact of remote working on wellbeing is described, according to the literature, and some thoughts on how remote working affects the future of coworking spaces and hybrid spaces are presented.
Acceleration of Remote Work and Coworking Practices in Estonia During the COVID-19 Pandemic

Published: May 2023

AbstractEstonia is a country with a small economy and a high level of digitalization that was more ready for remote work during the COVID-19 pandemic than many other countries. This paper shows how a small and flexible society with its institutions reacted to turbulent times and what developments it has brought along. We use data from Statistics Estonia and other public sources, as well as previous qualitative studies on coworking spaces in Estonia. We conclude that employees’ preferences towards hybridity and remote practices and the readiness of employers to meet them, supported by the high pre-pandemic level of digitalization and developed ICT sector, could improve the revitalization of rural and deprived regions and reduce the socioeconomic disparities across Estonia.

Authors: Belvončíková Eva , Danko Lukáš , Rafaj Oliver 
Published: May 2023

AbstractOperation of the coworking spaces (CSs) all over the world was strongly impacted by the COVID-19 pandemic, including those in Slovakia. The capital city’s CSs and coworking spaces localised in non-metropolitan eastern part confirmed decline in co-worker presence that have also influenced financial aspect of the coworking spaces stability and resilience. Even though there have been several possibilities of national and local grants from public authorities, this support was not widely used and no CSs decided to contact the owners of premises in order to get rent deferrals and/or rent discounts. The pandemic also caused switch of physical events into online activities and activate those spaces located in the eastern part of the country as the number of the events in these spaces overall increased. Even the community spirit inside the CSs transformed to community events decreased due to the adaptation of government measures, cooperation outside individual CSs have strengthen and lead to establishing of formalised coworking association in Slovakia. In spite of the difficult situation the CSs have to face, many of them realised the need of adaptation and invested in ICT devices, change of already not sufficient marketing strategies but also see business opportunities as several new coworking spaces have started to operate. All these aspects point at the fact that flexible work arrangement coworking spaces offer could help to solve global economic crisis.
