Published: September 2021

AbstractTo improve both thermal stability and friction durability of flexible electronic films with nano‐Ag, a series of flexible films with dendric nano‐Ag embedded into high thermally stable 2‐adamantane containing poly(aryl ether ketone) (2‐ADMPEK, PAEK) substrates are prepared in this work. These films are named as PAEK‐dnAg. The dendric nanostructure of Ag conductive layer performs excellent conductivity with sheet resistance as low as 0.3959 Ω ◻−1. The wide‐angle X‐ray diffraction and scanning electron microscope (SEM) results show dendric nano‐Ag layer well incorporated to PAEK substrates. The results of thermal stability, hydrolysis–oxidation test, adhesion test, and friction durability indicate the PAEK substrate can effectively protect dendric nanosilver conductive layer from heat, harsh oxidation, and friction. The SEM images further show the dendric embedded structure can remain almost unchanged after high temperature (400 °C) heating in air, water boiling oxidation for 12 h, 2500‐cycle 3M tape peeling test, and harsh friction with sanding paper under 5 N, which should lead to the excellent durability of PAEK‐dnAg samples in harsh condition. Thus, PAEK‐dnAgs may show great potential in flexible electronic films application for harsh condition such as high temperature, hydrothermal environment or high friction.

AbstractWith the advancement of nanotechnology and electroactive materials, conventional textiles have transformed into a versatile wearable electronic platform that will inevitably escalate the development of next‐generation flexible electronics. Integration of nanoscale conductive particles such as polymers, metals, or nanocarbons into different structural textile design has simplified the way of personal interactive communications and portable sensing by distributing superior stretchability and functionality in a smart textile device. However, for the real‐life application, it is crucial to recognize the functional reliability of wearable textile electronics. This review comprehensively summarizes the recent progress in electronic textiles (e‐textiles) using different electroactive materials and textile architectures for numerous wearable applications. The first section highlights different textile architectures used in e‐textiles and their various properties. Various electroactive polymers from carbon, metal, and conductive polymers, including their electromechanical properties and wash durability, are then discussed. Subsequently, progress in textile‐based energy harvesting and storage, personal thermal management, flexible sensing, electrocardiography (ECG), electromagnetic interference shielding are presented. Finally, the remaining challenges regarding the current materials and processing strategies are pointed out, and practical strategies to fully realize e‐textile systems are suggested.

Published: September 2021

AbstractWe describe a series of air‐stable NiIII complexes supported by a simple, robust naphthyridine‐based ligand. Access to the high‐valent oxidation state is enabled by the CF3 ligands on the nickel, while the naphthyridine exhibits either a monodentate or bidentate coordination mode that depends on the oxidation state and sterics, and enables facile aerobic oxidation of NiII to NiIII. These NiIII complexes act as efficient catalysts for photoinduced C(sp2)−H bond trifluoromethylation reactions of (hetero)arenes using versatile synthetic protocols. This blue LED light‐mediated catalytic protocol proceeds via a radical pathway and demonstrates potential in the late‐stage functionalization of drug analogs.

Published: September 2021

AbstractDie Öl/Wasser‐Grenzfläche z. B. in Emulsionen wird oft durch Tenside stabilisiert. Folglich bestimmt die Koexistenz von Öl, Wasser und Tensid an der Öl/Wasser‐Grenzfläche die makroskopischen Eigenschaften wie Oberflächenspannung oder die Stabilität von Emulsionen. Wir zeigen mit der oberflächensensitiven Summenfrequenzspektroskopie (SFG), dass die Adsorption eines anionischen Tensids an die Öl/Wasser‐Grenzfläche die Stärke des elektrisches Felds an der Grenzfläche erhöht. Mit zunehmender Grenzflächenbedeckung nimmt die Ordnung der Ölmoleküle an der Grenzfläche durch die Interkalation der aliphatischen Ketten des Tensids und den Ölmolekülen zu. Bei hinreichend hohen Tensidkonzentrationen erreicht die Grenzflächenladung einen Maximalwert, gleichzeitig stellt sich eine geordnete Konformation der Ölmoleküle an der Grenzfläche ein. Dies führt zu einer signifikanten Abnahme der Grenzflächenspannung und ermöglicht eine verbesserte Emulsionsstabilität.

AbstractSynthetic photoelectrochemistry (PEC) is receiving increasing attention as a new frontier for the generation and handling of reactive intermediates. PEC permits selective single‐electron transfer (SET) reactions in a much greener way and broadens the redox window of possible transformations. Herein, the most recent contributions are reviewed, demonstrating exciting new opportunities, namely, the combination of PEC with other reactivity paradigms (hydrogen‐atom transfer, radical polar crossover, energy transfer sensitization), scalability up to multigram scale, novel selectivities in SET super‐oxidations/reductions and the importance of precomplexation to temporally enable excited radical ion catalysis.

Published: September 2021

AbstractA cooperative OSDA strategy is demonstrated, leading to novel high‐silica FAU zeolites with a large potential for disruptive acid catalysis. In bottom‐up synthesis, the symbiosis of choline ion (Ch+) and 15‐crown‐5 (CE) was evidenced, in a form of full occupation of the sodalite (sod) cages with the trans Ch+ conformer, induced by the CE presence. CE itself occupied the supercages along with additional gauche Ch+, but in synthesis without CE, no trans was found. The cooperation, and thus the fraction of trans Ch+, was closely related to the Si/Al ratio, a key measure for FAU stability and acidity. As such, a bottom‐up handle for lowering the Al‐content of FAU and tuning its acid site distribution is shown. A mechanistic study demonstrated that forming sod cages with trans Ch+ is key to the nucleation of high‐silica FAU zeolites. The materials showed superior performances to commercial FAU zeolites and those synthesized without cooperation, in the catalytic degradation of polyethylene.

Authors: Sahu Dhananjay , Sahu Raj Kumar , Patra Karali 
Published: September 2021

AbstractThe effects of solid fillers on optical, electrical, mechanical, and electromechanical actuation behavior of VHB 4910 elastomer is inadequate, possibly due to readiness as a foam tape that makes the filler reinforcement a challenging work. VHB 4910 is modified by filling graphene oxide (GO) particles to realize the influences on material behavior towards actuator applications. The elastomer samples are ultrasonicated, swollen then thermochemically cured in GO dispersed; deionized‐water, trimethylolpropane trimethylacrylate (TMPTMA) and toluene to prepare three different filled‐elastomers. Material modification is confirmed by analyzing optical micrograph, and FTIR spectra. Whereas, dielectric constant and Young's modulus are assessed to ensure the feasibility of modified elastomers for electromechanical actuation strain. Amongst the three, GO‐TMPTMA filled‐elastomer samples are considered to test electromechanical actuation using an in‐house designed diaphragm actuator. Results showed enhanced in‐plane actuation performance and electrical breakdown strength, dependent on the curing time and prestrain. This work may strengthen the future strategies of making VHB 4910‐composite for dielectric elastomer actuator based electromechanical devices.

Published: September 2021

AbstractThe detection of changes in the reactive oxygen species (ROS)/reactive sulfur species (RSS) couple is important for studying the cellular redox state. Herein, we developed a 1,8‐naphthalimide‐based fluorescence probe (NI) for the reversible detection of bisulfite (HSO3−) and hydrogen peroxide (H2O2) in vitro and in vivo. NI has been designed with a reactive ethylene unit which specifically reacts with HSO3− by a Michael addition reaction mechanism, resulting in the quenching of yellow fluorescence at 580 nm and the appearing of green fluorescence at 510 nm upon excitation at 500 nm and 430 nm, respectively. The addition product (NI−HSO3) could be specifically oxidized to form the original C=C bond of NI, recovering the fluorescence emission and color. The detection limits of NI for HSO3− and NI−HSO3 for H2O2 were calculated to be 2.05 μM and 4.23 μM, respectively. The reversible fluorescence response of NI towards HSO3−/H2O2 couple can be repeated for at least five times. NI is reliable at a broad pH range (pH 3.0–11.5) and features outstanding selectivity, which enabled its practical applications in biological and food samples. Monitoring the reversible and dynamic inter‐conversion between HSO3− and H2O2 in vitro and in vivo has been verified by fluorescence imaging in live HeLa cells, adult zebrafish and nude mice. Moreover, NI has been successfully applied to detect of HSO3− levels in food samples.

AbstractObjectivesTo evaluate and compare characteristics and clinical outcomes of percutaneous coronary intervention (PCI) among target vessel types in patients with a prior coronary artery bypass graft (CABG) surgery.BackgroundPatients with a prior CABG often require repeat revascularization with PCI. Graft PCI has been associated with worse outcomes compared to native vessel PCI, yet the optimal PCI strategy in prior CABG patients remains unknown.MethodsWe stratified prior CABG patients who underwent PCI at a tertiary‐care center between 2009 and 2017 by target vessel type: native vessel, venous graft, and arterial graft. The primary outcome of major adverse cardiac events (MACE) was a composite of all‐cause death, myocardial infarction, stent thrombosis, or target vessel revascularization up to 1 year post‐PCI.ResultsPrior CABG patients (n = 3983) represented 19.5% of all PCI interventions during the study period. PCI was most frequently performed on native vessels (n = 2928, 73.5%) followed by venous (n = 883, 22.2%) and arterial grafts (n = 172, 4.3%). Procedural success and complications were similar among the groups; however, slow‐ and no‐reflow phenomenon was more common in venous graft PCI compared to native vessel PCI (OR 4.78; 95% CI 2.56–8.95; p < 0.001). At 1 year, there were no significant differences in MACE or in its individual components.ConclusionsTarget vessel choice did not appear to affect MACE at 1 year in a large cohort of patients with prior CABG undergoing PCI. Whether PCI of surgical grafts versus native arteries truly results in similar outcomes warrants further investigation in randomized controlled trials.
Role of the Supporting Electrolyte Ions and Additives on the Electron Transport Properties of Electrografted Films Bearing Ferrocenyl Moieties

Published: September 2021

AbstractThe electrochemical oxidation of 6‐ferrocenylheptanoate was used to modify the surface of glassy carbon electrodes with thin films bearing ferrocene molecules. These films grow layer by layer and behave as surface redox catalyst during the electrografting. The electrografted films have a structure with pinholes or channels, whose existence was deduced from the redox behavior of the film in acetonitrile solution containing different supporting electrolytes and organic additives. The electron transport through this film requires the presence of the electrolyte anions in the film channels. However, the voltametric feature of the grafted films is sensitive to the electrolyte cation size. The supporting electrolyte anions inside the film channels stabilize the ferrocenium species during the film oxidation. However, the presence of the cations is required to keep the inner charge balance. The inclusion of both anions and cations inside the grafted film determines the surface coverage obtained from the voltammetric experiments.

Function of chromatin modifier Hmgn1 during neural crest and craniofacial development
Authors: Ihewulezi Chibuike , Saint‐Jeannet Jean‐Pierre 
Published: September 2021

SummaryThe neural crest is a dynamic embryonic structure that plays a major role in the formation of the vertebrate craniofacial skeleton. Neural crest formation is regulated by a complex sequence of events directed by a network of transcription factors working in concert with chromatin modifiers. The high mobility group nucleosome binding protein 1 (Hmgn1) is a nonhistone chromatin architectural protein, associated with transcriptionally active chromatin. Here we report the expression and function of Hmgn1 during Xenopus neural crest and craniofacial development. Hmgn1 is broadly expressed at the gastrula and neurula stages, and is enriched in the head region at the tailbud stage, especially in the eyes and the pharyngeal arches. Hmgn1 knockdown affected the expression of several neural crest specifiers, including sox8, sox10, foxd3, and twist1, while other genes (sox9 and snai2) were only marginally affected. The specificity of this phenotype was confirmed by rescue, where injection of Hmgn1 mRNA was able to restore sox10 expression in morphant embryos. The reduction in neural crest gene expression at the neurula stage in Hmgn1 morphant embryos correlated with a decreased number of sox10‐ and twist1‐positive cells in the pharyngeal arches at the tailbud stage, and hypoplastic craniofacial cartilages at the tadpole stage. These results point to a novel role for Hmgn1 in the control of gene expression essential for neural crest and craniofacial development. Future work will investigate the precise mode of action of Hmgn1 in this context.

Published: September 2021

AbstractThe dentate gyrus not only gates the flow of information into the hippocampus, it also integrates and processes this information. Mossy cells (MCs) are a major type of excitatory neuron strategically located in the hilus of the dentate gyrus where they can contribute to this processing through networks of synapses with inhibitory neurons and dentate granule cells. Some prior work has suggested that MCs can form excitatory synapses with other MCs, but the role of these synapses in the network activity of the dentate gyrus has received little attention. Here, we investigated synaptic inputs to MCs in mouse hippocampal slices using a genetically encoded hybrid voltage sensor (hVOS) targeted to MCs by Cre‐lox technology. This enabled optical recording of voltage changes from multiple MCs simultaneously. Stimulating granule cells and CA3 pyramidal cells activated well‐established inputs to MCs and elicited synaptic responses as expected. However, the weak blockade of MC responses to granule cell layer stimulation by DCG‐IV raised the possibility of another source of excitation. To evaluate synapses between MCs as this source, single MCs were stimulated focally. Stimulation of one MC above its action potential threshold evoked depolarizing responses in neighboring MCs that depended on glutamate receptors. Short latency responses of MCs to other MCs did not depend on release from granule cell axons. However, granule cells did contribute to the longer latency responses of MCs to stimulation of other MCs. Thus, MCs transmit their activity to other MCs both through direct synaptic coupling and through polysynaptic coupling with dentate granule cells. MC–MC synapses can redistribute information entering the dentate gyrus and thus shape and modulate the electrical activity underlying hippocampal functions such as navigation and memory, as well as excessive excitation during seizures.

AbstractIssue AddressedIncreasing physical activity of adolescent girls is a key priority for health promotion, as their physical activity levels are generally lower than boys. This study aims to understand the experiences of adolescent girls who play Australian Football League Women's (AFLW) football and to explore girls’ pathways to playing football. Understanding how AFLW and gender norms/stereotypes influence girls’ experiences and self‐perceptions was a key focus.MethodsA qualitative description design and purposive sampling were used. Six adolescent girls aged 11‐17 that play football in urban Victoria, Australia participated. Short interview survey questions covering demographic and football pathway information were administered prior to online one‐on‐one interviews. Interviews lasted 30‐45 minutes. Questions were framed broadly, open‐ended and non‐directive (some using image prompts). Data were analysed using thematic analysis.ResultsThe results cover four themes: (a) Self‐perception—participants presented with positive self‐perceptions, (b) Social support—a supportive team and exposure to women playing football, and family support/involvement, were encouraging factors in pathways to playing football, (c) AFLW role models—were positive influences on participants’ experience and self‐perceptions and (d) Influence of gender norms/stereotypes—participant self‐perceptions displayed conforming and non‐conforming features of gender norms/stereotypes. Participants reported exposure to sexist commentary about girls in sport through social media and peers but instead of being discouraged, most used it as motivation or empowerment, while others were dismissive.ConclusionsFindings suggest increased media coverage of AFLW players may be beneficial. Education programs/initiatives which i) involve AFLW role models and ii) encourage family friendly club environments and team bonding spaces are recommended.So what?Findings indicate that adolescent girls can thrive in their football experience, which could increase feelings of empowerment and foster positive self‐perceptions, contributing to overall health. Further research in this area is recommended to expand on and strengthen our study findings.

Published: September 2021

AbstractAs a developing country, Pakistan reports a high burden of fungal diseases, of which cutaneous mucormycosis remains a prominent infection, presenting as a highly invasive disease with significant mortality. Apart from a high population of at‐risk individuals, multiple factors have precipitated an increment in mucormycosis cases in the country following the COVID‐19 pandemic. These include increased use of corticosteroids, immunosuppression following the viral infection, prolonged stays in the intensive care unit and sub‐optimal laboratory testing available in the country. This article aims to assess the potential implications of a mucormycosis epidemic on a healthcare system already strained under the COVID‐19 pandemic, and provides subsequent recommendations to weather the dual challenge of two deadly pathogens.
