Published: October 2024

AbstractAimBear‐related trauma is a significant concern in Japan. This study identified trauma patterns, outcomes, and therapeutic approaches for bear‐related injuries treated.MethodsThis retrospective observational study used medical records from Akita University Hospital, focusing on patients with bear‐related trauma in 2023. Demographic data, injury details, treatment procedures, and outcomes were extracted.ResultsThe study included 20 patients (median age: 74.5 years, 65% males). Most injuries occurred in human habitats, mainly in autumn, with the face being the most affected area (90%). Three patients required emergency transfusions and tracheal intubation. Emergency surgery was performed in 52.6% of patients, and 42.1% were admitted to the intensive care unit. All patients survived with a median hospital stay of 17 days. However, 15.8% of patients had significant sequelae, such as blindness. Despite prophylactic antibiotics, wound infections occurred in 21.1% of patients, particularly in deep wounds that were not adequately washed under general anesthesia.ConclusionsBear‐related trauma often results in severe upper‐body injuries that require prompt medical intervention. These findings highlight the need for improved preventive measures and strategies for initial treatment and long‐term care.

Published: October 2024

AbstractChlorine (Cl2) is one of the most important commodity chemicals that has found widespread utility in chemical industry. Most Cl2 is currently produced via the chlorine evolution reaction (CER) at the anode of chlor–alkali electrolyzers, for which platinum group‐metal (PGM)‐based mixed metal oxides (MMOs) have been used for more than half a century. However, MMOs suffer from the use of expensive and scarce PGMs and face selectivity problems due to the parasitic oxygen evolution reaction. Over the last decade, the field of CER catalysis has seen dramatic advances in both the theory and discovery of new catalysts. Theoretical approaches have enabled a fundamental understanding of CER mechanisms and provided catalyst design principles. The exploration of new materials has led to the discovery of CER catalysts other than MMOs, including non‐PGM oxides, atomically dispersed single‐site catalysts, and organic molecules, with some of which following novel reaction pathways. This minireview provides an overview of the recent advances in CER electrocatalyst research and suggests future directions for this revitalized field.

AbstractDirectly converting CO2 in flue gas using artificial photosynthetic technology represents a promising green approach for CO2 resource utilization. However, it remains a great challenge to achieve efficient reduction of CO2 from flue gas due to the decreased activity of photocatalysts in diluted CO2 atmosphere. Herein, we designed and synthesized a series of dual metallosalen‐based covalent organic frameworks (MM‐Salen‐COFs, M: Zn, Ni, Cu) for artificial photosynthetic diluted CO2 reduction and confirmed their advantage in comparison to that of single metal M‐Salen‐COFs. As a results, the ZnZn‐Salen‐COF with dual Zn sites exhibits a prominent visible‐light‐driven CO2‐to‐CO conversion rate of 150.9 μmol g−1 h−1 under pure CO2 atmosphere, which is ~6 times higher than that of single metal Zn‐Salen‐COF. Notably, the dual metal ZnZn‐Salen‐COF still displays efficient CO2 conversion activity of 102.1 μmol g−1 h−1 under diluted CO2 atmosphere from simulated flue gas conditions (15 % CO2), which is a record high activity among COFs‐ and MOFs‐based photocatalysts under the same reaction conditions. Further investigations and theoretical calculations suggest that the synergistic effect between the neighboring dual metal sites in the ZnZn‐Salen‐COF facilitates low concentration CO2 adsorption and activation, thereby lowering the energy barrier of the rate‐determining step.

AbstractFiber zinc‐air batteries are explored as promising power systems for wearable and portable electronic devices due to their intrinsic safety and the use of ambient oxygen as cathode material. However, challenges such as limited zinc anode reversibility and sluggish cathode reaction kinetics result in poor cycling stability and low energy efficiency. To address these challenges, we design a polydopamine‐based all‐in‐one gel electrolyte (PAGE) that simultaneously regulates the reversibility of zinc anodes and the kinetics of air cathodes through polydopamine interfacial and redox chemistry, respectively. The intrinsic catechol and carboxylate groups in PAGE regulate the transport and solvation structure of Zn2+, facilitating dendrite‐free zinc deposition with a lamellar stacking morphology. Additionally, the oxidation of redox‐active catechol groups in PAGE replaces the sluggish oxygen evolution reaction on the air cathode and reduces the energy barrier for charging, enabling fiber zinc‐air batteries to achieve a significantly improved energy efficiency of 95 % and a longer lifespan of 40 hours. Further integration into self‐powered electronic textiles underscores its potential for next‐generation wearable systems.

AbstractAiming at numerous defects at SnO2/perovskite interface and lattice mismatch in perovskite solar cells (PSCs), we design a kind of three‐dimensional (3D) molecular glue (KBF4‐TFMSA), which is derived from strong intramolecular hydrogen bonding interaction between potassium tetrafluoroborate (KBF4) and trifluoromethane‐sulfonamide (TFMSA). A remarkable efficiency of 25.8 % with negligible hysteresis and a stabilized power output of 25.0 % have been achieved, in addition, 24.57 % certified efficiency of 1 cm2 device is also obtained. Further investigation reveals that this KBF4‐TFMSA can interact with oxygen vacancies and under‐coordinated Sn(IV) from the SnO2, in the meantime, FA+ (NH2−C=NH2+) and K+ cations can be well fixed by hydrogen bonding interaction between FA+ and BF4−, and electrostatic attraction between sulfonyl oxygen and K+ ions, respectively. Thereby, FAPbI3 crystal grain sizes are increased, interfacial defects are significantly reduced while carrier extraction/ transportation is facilitated, leading to better cell performance and excellent stabilities. Non‐encapsulated devices can maintain 91 % of their initial efficiency under maximum‐power‐point (MPP) tracking while continuous illumination (~100 mW cm−2) for 1000 h, and retain 91 % of the initial efficiency after 1000 h “double 60” damp‐heat stability testing (60 °C and 60 %RH (RH, relatively humidity)).

Published: October 2024

AbstractChiral catalysts for asymmetric catalysis represent a crucial research focus in chemistry and materials science. However, a few cases about chiral‐dependent photocatalysts primarily focus on plasmonic noble metals. Particularly, developing chiral nano‐catalysts that can be driven by mechanical energy remains in the blank stage. Herein, organic polymer‐based enantiomers, chiral polar polyimide (PI) microspheric nano‐assembly are synthesized as novel bifunctional catalysts for asymmetric photocatalysis and piezocatalysis. The PI catalyst enantiomers present enantioselectivity towards left‐ and right‐circularly polarized light, demonstrating chiral‐dependent H2O2 photoproduction. Interestingly, enantioselectivity of the catalyst reverses under irradiation of different bands, presenting tunability in the interaction between chiral catalysts and circularly polarized light. For the first time, enantioselective piezocatalytic behavior is demonstrated by the chiral polar PI catalysts. They show remarkable chiral preference for asymmetric Diels–Alder reaction and enantioselective conversion of tyrosine substrates under ultrasonic vibration. The findings provide a new perspective into exploring metal‐free chiral catalysts and their asymmetric catalysis applications across multiple energy forms.

Published: October 2024

AbstractMultimodal upconversion and downshifting circularly polarized luminescent materials hold significant potential for optical anticounterfeiting applications due to their exceptional chiroptical properties. However, constructing these materials within a single emitter remains challenging. In this study, a conceptual model of multimodal upconversion/downshifting circularly polarized luminescence (CPL) is realized within a single nanoparticle. A new type of nanoparticles with multilayer core–shell architecture is fabricated, capable of delivering upconversion/downshifting luminescence, when excited by a 980 nm laser. Utilizing a co‐assembly strategy, multimodal upconversion/downshifting CPL emission, covering a broad emission range from ultraviolet (UV) to the second near‐infrared (NIR‐II) region, can be realized at the supramolecular level. These chiroptical properties closely follow the chirality of host matrix and are strongly dependent on the distribution mode of nanoparticles within the matrix films. The multimodal upconversion/downshifting CPL behavior enabled cutting‐edge encryption applications including optical anticounterfeiting and information encryption. This work introduces a novel approach to designing multimodal upconversion/downshifting CPL materials and opens new avenues for the development of chiroptical functional materials.
An exploration of the cognitive and affective processes for anaesthetists when performing an emergency front of neck airway*
Authors: Kidd L. R. , Wegrzynek P. , Newell C. , Wainwright E. 
Published: October 2024

SummaryEmergency front of neck airway (eFONA) is a potentially lifesaving but very high‐stress procedure. We explored the cognitive and affective processes involved via semi‐structured interviews with 17 UK anaesthetists who had attempted eFONA within the previous two years. Thematic analyses generated two meta‐themes: ‘Making the decision is the hardest part; the doing is easier’ and ‘What helps make the decision?’. We found concerns around scrutiny, lack of a flat hierarchy, unfamiliarity with the situation and the lack of a model for transitioning to eFONA. Culture change, using a shared mental model, priming and emotional disengagement, assisted with eFONA decision‐making. Conclusions and implications for practice are presented.

ABSTRACTA reciprocating hydrogen compressor status monitoring system for predictive maintenance is developed based on HHT (Hilbert−Huang Transform) with multiple functions, strong applicability, and high accuracy to address the problem of difficulty in identifying fault signals and failure to provide advance warning before faults occur in the reciprocating hydrogen compressor state monitoring system. Design framework of monitoring system is confirmed, and function modules are designed based on LabView platform. HHT is applied to monitor the status of reciprocating hydrogen compressor based on LabView platform. A reciprocating hydrogen compressor is selected as research object, status monitoring analysis is carried out. Five working states of reciprocating hydrogen compressor are collected, which conclude normal state, filler malfunction, cross‐head malfunction, air valve malfunction, and piston rod malfunction. HHT is carried out for five signals, and results show that HHT marginal spectrum of five signals has different characteristics. Based on comparison results, precision of HHT ranges from 0.757 to 0.784, recall of HHT ranges from 0.738 to 0.766, F1‐score of HHT ranges from to 0.788 to 0.804, HHT has better performance than other two methods. Proposed monitoring system designed in this study provides a comprehensive and efficient online monitoring and data analysis solution for reciprocating hydrogen compressors, which can achieve fault prediction of reciprocating hydrogen compressor, reduce failure rate, and effectively improve the reliability of the compressor oil injection system.
End Group Effects on Anion Binding in Tetraglycine Peptide: A Computational Study

Published: October 2024

AbstractThe importance of anions in various processes has led to a search for molecules that can effectively recognize and interact with these anions. This study explores how the tetraglycine [(Gly)4] peptide in its zwitterionic, neutral, and terminally capped forms acts as a receptor for H2PO4− and HSO4− anions within the framework of supramolecular host‐guest chemistry. Using molecular dynamics (MD) simulations, we obtained the conformations of the receptor‐anion complexes. Density functional theory (DFT), quantifies the complexes’ interaction energies in both gas and solvent phases. Proton transfer within the zwitterionic complex with H2PO4− anion alters peptide charge distribution, affecting its conformation and binding site arrangement, as analysed by quantum mechanics/molecular mechanics (QM/MM) methods. Symmetry‐adapted perturbation theory (SAPT) and noncovalent interactions analysis highlight the role of electrostatic interactions in these receptor‐anion complexes. It emphasizes the key interactions such as N−H⋅⋅⋅⋅O and O−H⋅⋅⋅O=C between the peptide backbone and anions and elucidates the molecular recognition mechanism driven by crucial noncovalent interactions. The termination of the peptide's end groups modulates anion binding sites from the backbone to the charged N‐terminal, resulting in distinct binding sites. Our findings provide insights for designing peptides tailored to function as anion receptors in diverse supramolecular chemistry applications.
Understanding teacher ethico‐political identity formation from a Foucauldian perspective
Authors: Carswell Desmond , Conway Paul F. 
Published: October 2024

AbstractIn recent years, we have seen an increased politicisation and objectification of what teachers should know, what teachers should do and who teachers should be while they are doing it. While evident across the continua of teacher education, such politicised constructions are particularly acute at initial teacher education. Given such attention to constructing what has been described as a ‘preferred’ teacher identity, this paper explores how prospective teachers construct themselves in ethico‐political terms (i.e., how prospective teachers construct the relationship that they have with themselves and how they account for themselves in that regard). Informed by a Foucauldian perspective and using a composite case that draws on interview data (photovoice and semi‐structured interviews) from a small sample (n = 4) of prospective Irish primary school teachers at various stages during their final semester of initial teacher education, this paper addresses ethico‐political identity in terms of substance, authority sources, self‐practices and telos. Findings illuminate prospective teacher ethico‐political identity as: (i) substance as the basis for nascent teacher practical knowing‐in‐action and pedagogical sensitivities; (ii) temporally organised authority sources; (iii) dynamic and interrelated self‐practices; and (iv) telos as a form of identity prolepsis that emphasises three major valuational endpoints. The paper concludes by contemplating the generativity of an ethico‐political conceptualisation of teacher identity (re)formation for teacher education purposes in terms of its conceptual, contextual, critical and reflective utility.
Does green imprinting affect green entrepreneurial behaviors? The application of imprinting theory and stimulus‐organism‐response theory
Authors: Zhou Jian , Wu Zexin 
Published: October 2024

AbstractGreen entrepreneurship has become pivotal for mitigating resource wastage and safeguarding the ecological environment within the framework of green economic development. Scholars have paid scant attention to investigating the transformation and advancement of green imprinting in shaping individual green entrepreneurial behaviors. In this study, we address this gap by integrating imprinting theory and the stimulus‐organism‐response (SOR) theory, constructing a comprehensive mediating moderation model encompassing green imprinting, green entrepreneurial intentions, green entrepreneurial behaviors, and green self‐efficacy. Through an empirical examination of 331 valid questionnaire responses, we identify two distinct dimensions of green imprinting. Both positive and negative green imprinting exert a notable influence on green entrepreneurial behaviors, with green entrepreneurial intentions serving as a mediating factor between green imprinting and actual entrepreneurial behaviors. Our research carries substantial theoretical and practical implications, enriching our comprehension of the mechanisms underlying green imprinting and providing guidance for entrepreneurs engaged in green business ventures.

AbstractIn this study, the binding behavior of β‐sitosterol with lysozyme (LZM) was elucidated by surface plasmon resonance (SPR), computational molecular docking and molecular dynamics simulation studies. Chicken egg white lysozyme (CEWLZM) served as a model protein. Tri‐N‐acetylchitotriose (NAG3) was used in the redocking experiments to generate precise binding location of the protein. β‐sitosterol displayed a slightly better binding energy (−6.68±0.04 kcal/mol) compared to NAG3. Further molecular dynamics simulations and MMPBSA analysis revealed that residues Glu35, Gln57‐Asn59, Trp62, Ile98, Ala107 and Trp108 contribute to the binding energy. Then, 2.5 mg/mL CEWLZM, 1X PBS buffer (pH 7.4) as running and coupling buffers, 30 μL/min as flow rate were applied for SPR analysis. Serial β‐sitosterol injections (20–150 μM) were performed through SPR sensor surface. According to SPR binding study, KD value for β‐sitosterol‐CEWLZM binding interaction was calculated as 71.34±9.79 μM. The results could provide essential knowledge for nutrition, pharmaceutical science, and oral biology.

AbstractAlthough the nutritional and health benefits of Rumex species are well known, little is known about the chemical composition and pharmacological activities of Rumex balcanicus Rech. fil. (Polygonaceae), an endemic plant of the Balkan Peninsula. To the best of our knowledge, this paper represents the first attempt to comparatively analyse phenolic composition, as well as in vitro pharmacological activites of dry hydromethanol extracts of R. balcanicus fruit (RBF), leaf (RBL) and root (RBR), collected in Serbia. The maximum total phenolic content was found in RBF (386.6 mg GAE/g). The RBF was characterized by high amounts of miquelianin (28.8 mg/g) and procyanidin B1 (28.1 mg/g). The RBL was the richest in quercitrin (18.4 mg/g) and miquelianin (15.0 mg/g), while nepodin (54.1 mg/g) and procyanidin B2 (40.6 mg/g) were the major compounds in RBR. The RBF exhibited significant antioxidant activity, evaluated by DPPH (IC50=4.9 μg/mL), ABTS (IC50=0.8 μg/mL) and FRAP (5.9 mmol Fe2+/g) assays. Moreover, RBF showed strong α‐glucosidase inhibitory activity (IC50=1.8 μg/mL), in addition to notable anti‐α‐amylase, anti‐acetylcholinesterase and anti‐tyrosinase activities. Molecular docking analysis predicted miquelianin and procyanidin B2 as the greatest inhibitors of these enzymes. Overall, R. balcanicus fruits stood out as the most promising plant material worth further research.

AbstractThe genera Geranium and Erodium (Geraniaceae) have been documented to possess diverse ethnopharmacological uses, including diabetes mellitus. Relevant to their ethnopharmacological use, the current study aimed to evaluate the α‐glucosidase, α‐amylase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) enzyme inhibitory activity of ethanol extracts from 46 samples belonging to thirty‐one species of Geranium (20) and Erodium (11) collected throughout Türkiye. The majority of the extracts displayed a marked α‐glucosidase and α‐amylase inhibitory activity. Besides, 23 extracts out of 46 exhibited a concentration‐dependent inhibitory effect over 50 % towards AChE. The highest AChE inhibition was found in G. subcaulescens collected from Konya with an IC50 value of 4.73±2.96 μg/mL. E. somanum, E. leucanthum, and E. sipthorpianum exhibited the most potent α‐glucosidase inhibitory activity, while E. birandianum and E. pelargoniiflorum were the most active extracts against AChE and BChE, respectively. Three extracts that had inhibitory activity over 50 % against four of the enzymes were selected and proceeded to RP‐HPLC analysis. Geraniin and ellagic acid were identified as major compounds in the active extracts. Most species screened in the current study were examined for the first time against α‐glucosidase, α‐amylase, AChE, and BChE.
