AbstractAn urgent challenge to the development of rechargeable Zn–air batteries (RZABs) is the highly active, durable, and low‐cost catalysts for oxygen reduction reaction and oxygen evolution reaction (ORR and OER). Herein, a carbon‐based monolithic catalyst is designed via anchoring P‐modified MnCo2O4 inverse spinel nanoparticles on biomass‐derived carbon (P‐MnCo2O4@PWC). The introduction of surface P atoms regulates the electronic structures and valences of metal atoms by adjusting the coordination fields by (P‐O)δ– and Metal‐P. The optimization of the adsorption behavior of key intermediates facilitates the activation and conversion of reaction species. The monolithic structure is beneficial to the construction of a three‐phase interface for efficient mass transfer and high electrical conductivity. The P‐MnCo2O4@PWC catalyst displays outstanding bifunctional catalytic properties with a thin ΔE (the difference between the OER potential at 10 mA cm–2 and the ORR halfwave potential) of 0.66 V. The RZAB with P‐MnCo2O4@PWC as cathode delivers an exceptional peak power density (160 mW cm–2) and remarkable cycle life (over 1200 cycles), overcoming those with noble metal counterparts. This research provides a promising general surface‐phosphorization way to the design of carbon electrocatalysts and the high‐value utilization of biomass.

Published: July 2024

AbstractBacterial infections, especially those from drug‐resistant strains, pose a significant threat to healing diabetic skin injuries, with current treatments being intricated and often unsatisfactory. Inspired by octopuses, a biomimetic material using α‐cyclodextrin (α‐CD) and polyethylene glycol (PEG) assembled with graphene oxide end‐capped polyrotaxanes (GO‐PR) is developed, where α‐CD mimics the flexible tentacles of an octopus. Further, α‐CD is cationically modified with polyethyleneimine (PEI) to resemble octopus suction cups, creating GO‐PRP, which effectively captures and adheres to bacteria. Importantly, to emulate an octopus's ink defense, GO‐PRP is used as a carrier for nitric oxide (NO), resulting in GO‐PRP/NONOate. Utilizing the photothermal conversion of GO, near‐infrared light exposure triggers rapid heating and NO release, providing efficient antibacterial activity and biofilm dispersion, significantly reducing inflammation in diabetic skin injuries in type I rats. During wound healing, sustained NO release promotes vascular endothelial growth factor production and blood vessel regeneration, enhancing collagen formation and shortening the healing time for diabetic skin infections. Thus, octopus‐inspired GO‐PRP/NONOate emerges as a novel biomaterial for treating drug‐resistant bacterial infections in diabetic wounds in the biomedical field.

AbstractPhotocatalytic water splitting for hydrogen production represents a crucial approach for obtaining green energy through artificial solar energy utilization, offering a sustainable method for energy generation that helps mitigate energy shortages and protect the environment. Among the numerous photocatalytic materials, covalent organic frameworks (COFs) have garnered significant attention and intensive study from researchers due to their distinctive benefits, such as porosity, pre‐design capability, and tunability at the atomic level. Significant advancements are made in the development of materials, enhancement of performance, and comprehension of mechanisms. In this review, recent advancements in COF‐based photocatalytic water splitting are spotlighted, both in half‐reactions and overall reactions, with a particular emphasis on the rational design of COF structures to regulate the materials' optical and electrical properties, as well as the fundamental processes of photocatalysis. Drawing from current research in this field, the existing challenges, and potential opportunities are also discussed for future development.

Published: July 2024

AbstractOne of the hallmarks of tissue repair is the production of reactive oxygen species (ROS), which modulate processes such as cell proliferation. Although several attempts have been made to manipulate ROS levels to increase tissue repair, the lack of techniques able to remotely manipulate the redox homeostasis with spatio–temporal fashion has hindered its progress. Herein, a new approach for tuning the ROS levels using magnetic nanoparticles (MNPs) that act as nanoheaters when exposed to an alternating magnetic field is presented. Two manganese–iron oxide (MnxFe3−xO4) MNPs (with a low and a high Mn2+ content) are designed and probed for the possibility of modulating the ROS balance by magneto–thermal stimulation in the invertebrate model organism Hydra vulgaris, able to fully regenerate. By evaluating the expression of selected genes involved in the maintenance of ROS homeostasis and proliferation pathways, a biphasic modulation of the ROS levels played by the MNPs is found. While MNPs with a lower Mn2+ content are able to positively modulate the regeneration potential under magnetostimulation, MNPs with a higher Mn2+ content cause a different redox imbalance, negatively affecting the regeneration dynamic. This innovative approach reveals a novel way of manipulating redox homeostasis that can advance in the field of tissue engineering.
Magneto‐Ionic Control of Coercivity and Domain‐Wall Velocity in Co/Pd Multilayers by Electrochemical Hydrogen Loading

Published: July 2024

AbstractMagneto‐ionics, as the electrochemical reconfiguration of magnetic materials at low gating voltages, is a highly energy‐efficient alternative to control magnetism. For the fastest magneto‐ionic concept based on hydrogen, fundamental mechanisms are currently under debate, mainly because quantitative compositional information inside the magnetic materials upon gating is lacking. Using the electrochemical hydrogen loading of Co/Pd multilayers with perpendicular anisotropy, this study demonstrates that the hydrogen concentration inside the magnetic material determines its magnetic properties. Hydrogen concentrations up to a maximum of (0.24 ± 0.01) hydrogen atoms per metal atom can be set deterministically by voltage and are quantified via flow‐cell coulometry. With increasing hydrogen concentration, a continuous increase in coercivity of up to 15% and a decrease in magnetic domain‐wall velocity by an order of magnitude are observed using in situ MOKE microscopy. This enables the voltage‐controlled stop‐and‐go of domain walls. These magneto‐ionic effects can be explained by an increasing perpendicular anisotropy with increasing hydrogen content in Co/Pd multilayers, which is supported by theory. Importantly, the approach should be transferable to other ionic systems, such as lithium‐ or oxygen‐based ones, where it can uncover the yet hidden effects of ionic concentration on the magnetic properties and guide the design of functional magneto‐ionic devices.

Published: July 2024

AbstractThe Russian invasion of Ukraine in February 2022 had profound consequences for the global economy. As both countries are major commodity exporters, the food value chain was also affected. This study investigates the impact of the invasion on stock prices, profitability and sentiments of agribusinesses along the food supply chain by using an event study, financial data, and a sentiment analysis of annual reports. Overall, the findings show that firms in the food value chain were negatively impacted, with regional and sector‐specific differences. Agribusiness firms in Europe and Japan were more negatively impacted by the war than those in the United States. Stock prices of Brewers, Packaged Food and Meats, Soft drinks, and Tobacco firms were negatively impacted by the invasion, while other sectors experienced no or little impact on stock prices. Fertilizers and Agrochemicals firms overall achieved a higher profitability in 2022 compared to previous years. [EconLit Citations: G01, G12, E44, Q01].

AbstractDie Hydrostannylierung der wichtigen Basischemikalie weißer Phosphor (P4) ermöglicht in einer Eintopf‐Reaktion und sogar auf katalytischem Weg die Synthese nützlicher P1‐Produkte. Bisher ist das mechanistische Verständnis dieser Methode jedoch mangelhaft, was die Nutzung für weitere Reaktionen einschränkt. Mit Hilfe von sterisch anspruchsvollen Zinnhydriden, zeitaufgelösten 31P‐NMR‐Experimenten und DFT‐Rechnungen geben wir nun fundierte Einblicke in den Mechanismus der P4‐Hydrostannylierung und beschreiben die Identifikation und Isolierung bisher unbekannter Reaktionsintermediate. Die Ergebnisse erlauben Rückschlüsse zur Kinetik der Reaktion und liefern praktische Hinweise für zukünftige Arbeiten auf dem Gebiet der P4‐Aktivierung.

Published: July 2024

AbstractAlthough aversive responses to sensory stimuli are common in autism spectrum disorder (ASD), it remains unknown whether the social relevance of aversive sensory inputs affects their processing. We used functional magnetic resonance imaging (fMRI) to investigate neural responses to mildly aversive nonsocial and social sensory stimuli as well as how sensory over‐responsivity (SOR) severity relates to these responses. Participants included 21 ASD and 25 typically‐developing (TD) youth, aged 8.6–18.0 years. Results showed that TD youth exhibited significant neural discrimination of socially relevant versus irrelevant aversive sensory stimuli, particularly in the amygdala and orbitofrontal cortex (OFC), regions that are crucial for sensory and social processing. In contrast, ASD youth showed reduced neural discrimination of social versus nonsocial stimuli in the amygdala and OFC, as well as overall greater neural responses to nonsocial compared with social stimuli. Moreover, higher SOR in ASD was associated with heightened responses in sensory‐motor regions to socially‐relevant stimuli. These findings further our understanding of the relationship between sensory and social processing in ASD, suggesting limited attention to the social relevance compared with aversiveness level of sensory input in ASD versus TD youth, particularly in ASD youth with higher SOR.

AbstractAlthough environmental, social, and governance (ESG) have been recognized for its overall impact on firm efficiency, research on the effects of the three main and multiple sub elements of ESG, especially in the airline industry, has been lacking. Thus, we analyze the impacts of overall ESG, its three main elements, and each sub elements of ESG on the firm efficiency of 29 suppliers, partners, and customers of Japan Airlines over the period of 2013–2022. First, we employ a two‐stage hierarchical network data envelopment analysis (DEA) technique that assesses the interrelationships and interdependencies among the supply chain players in contributing toward achieving their respective operating and profitability efficiencies. Second, we run ordinary least squares regression analyses with 5000 bootstrap replications and determine that overall ESG and its three main elements are positively linked with firm efficiencies. The sub elements of ESG have different impacts on firm efficiencies. That is, resource use and environmental innovation under the Environmental element and human rights and product responsibility under the Social element show significantly positive associations with firm efficiencies. All Governance sub elements positively affect firm efficiencies. The outcomes of this study will be valuable for managers at Japan Airlines and other policymakers within its supply chain because it highlights the importance of focusing on the three main and sub elements of ESG and employing the accurate firm efficiency measurement method when interrelationships and interdependencies of decision‐making units exist.

AbstractObjectiveDistress during SARS‐CoV‐2 outbreak affected also cancer patients' well‐being. Aim of this study was to investigate patient' reactions and behavior (flexible‐adaptive vs. inflexible‐maladaptive) during the SARS‐CoV‐2 outbreak.MethodsA cross‐sectional survey was designed with a self‐report questionnaire, “the ImpACT questionnaire,” developed for the study. Regression analysis was performed on data.ResultsFour hundred and forty five cancer patients from 17 Italian regions participated in the study. 79.8% of participants were female (mean age of 58 years). 92.6% of participants reported feeling vulnerable to COVID‐19 contagion; 75.6% reported helpless, 62.7% sad, 60.4% anxious, and 52.0% anger. Avoidance of thinking about coronavirus is the principal maladaptive behavior that emerged. Participants who reported feeling anxious were more likely to have fear of staff being infected with COVID‐19 (OR = 3.01; 95% CI = 1.49–6.30) and to have disrupted sleep due to worry (OR = 2.42; 95% CI = 1.23–4.83). Younger participants reported more anxiety (OR = 0.97; 95% CI = 0.94–1.00); men reported feeling calm more than women (OR = 2.60; 95% CI = 1.27–5.43).ConclusionsMajority of cancer patients reported serious concerns regarding SARS‐CoV‐2 infection; reliable information and psychological support must be offers to respond to these needs.
Student‐generated metaphor in research supervision: An arts‐based method
Authors: Ramsey‐Wade Christine E. , Cott Matthew J. 
Published: July 2024

AbstractPrevious research has highlighted the impact and importance of the use of client‐generated metaphor in psychotherapy (Cott, 2020). While researching this topic, we began to incorporate student‐generated metaphor into the research supervision process. This was found to enhance the supervision relationship, providing a quick and immediate insight into the supervisee's lived experience and pastoral needs at each stage of the research journey. This work developed into an arts‐based research supervision method, which reduced the power differential in the supervisory relationship, and made space for the supervisee to communicate their learning experience on their own terms. In this paper, we will set out the rationale for using student‐generated metaphor in research supervision and share further student feedback on this process, including future ideas for research and practice. We argue that theory and research on research supervision often neglect its pastoral component, and that providing excellent pastoral support to postgraduate researchers is key. The paper will conclude by making the case that the use of student‐generated metaphor in research supervision can be a simple and effective way to bring the supervisory relationship into focus.

AbstractResearch interest in examining Elaeagnus angustifolia’s potential as a source of anti‐inflammatory and antioxidant agents has grown as a result of the plant's endorsement as a rich source of bioactive chemicals with promising anti‐inflammatory and antioxidant activity. In this study, zinc oxide (Fe0.25‐ZnO) bimetallic nanoparticles (E.ang‐Fe0.25‐ZnO NPs) were synthesized using an aqueous extract of Elaeagnus angustifolia. Synthesized Fe0.25‐ZnO nanoparticles were characterized by FTIR and XRD. The anti‐inflammatory and antioxidant activities were investigated in LPS‐stimulated RAW 264.7 macrophages using RT‐PCR and ELISA techniques for antioxidant‐ and inflammation‐related genes. The concentration of 39.6 μg/ml of E.ang‐Fe0.25‐ZnO NPs demonstrated a significant anti‐inflammatory activity by suppressing the mRNA levels of TNF‐α and IL‐6 by 88.3 %±1.9 and 93.6 %±0.1, respectively, compared to LPS‐stimulated cells. This was confirmed by the significant reduction of TNF‐α and IL‐6 secretion levels from 95.2 and 495.6 pg/ml in LPS‐stimulated cells to 5.6 and 26.5 pg/ml in E.ang‐Fe0.25‐ZnO treated group. In addition, E.ang‐Fe0.25‐ZnO NPs nanoparticles treatment significantly enhanced the expression of antioxidant‐related genes, SOD and CAT. Together, our results proved that phyto‐mediated Fe0.25‐ZnO nanoparticles using Elaeagnus angustifolia have great potential in biomedical applications such as anti‐inflammatory and antioxidant.

AbstractThree previously undescribed protoilludane‐type sesquiterpene aryl esters, armillanals A−C (1–3), along with seven known ones (4–10) were obtained from Armillaria gallica Marxm. & Romagn. Compounds 1 and 2 were a rare class of sesquiterpenes featuring the Δ2(3) and Δ12(13)‐protoilludane skeleton. Their structures were established by extensive spectroscopic methods. Based on electronic circular dichroism (ECD) calculations, the absolute configurations of three new compounds (1–3) were determined. The anti‐inflammatory activity of compounds 1–10 was screened and compound 3 could dose‐dependently decrease the level of lactate dehydrogenase, showing IC50 value of 4.525 μM.

AbstractThis study investigates the integration of ZnO nanoparticles into the MIL‐100(Fe) framework using atomic layer deposition (ALD) at atmospheric pressure, varying ALD cycles from 0.5 to 2. The goal is to enhance the photocatalytic efficiency of MIL‐100(Fe) in water splitting under ultraviolet light. Among the composites, the ZnO/MIL‐100(Fe) synthesized with a 1‐cycle ALD process stands out, demonstrating superior hydrogen evolution rates (8465 μmol g−1 h−1) and improved durability, surpassing the base MIL‐100(Fe) in repeated photocatalytic water splitting (PWS) trials. Comprehensive characterization using various analytical techniques, including BET analysis, DRS, EDS, SEM, TEM, XRD, FT‐IR, Raman, and PL, sheds light on the structural, chemical, and optical properties of the MIL‐100(Fe)/ZnO materials, confirming successful ZnO deposition within the MIL‐100(Fe) structure. Furthermore, the enhancement in photocatalytic activity is associated with increased absorption intensity and reduced trap sites, implying improved charge carrier dynamics and separation. The inclusion of ZnO not only reduced the bandgap of composites, but also influences the photoluminescence characteristics significantly, leading to a reduction in non‐radiative recombination and enhancing the availability of photogenerated electrons for photocatalytic reactions. Specifically, the increased photoluminescence intensity observed with ZnO/MIL‐100(Fe) composites indicates a higher defect density, which corresponds to more active sites for photocatalysis.

AbstractA series of fluorescent carbazole‐coumarins exhibiting good photoluminescence quantum yields and thermally activated delayed fluorescence (TADF) properties have been designed and synthetized using computer‐aided density functional theory calculations. The TADF characteristics of the carbazole‐coumarins were systematically explored both in solution and in the solid state, utilizing poly(methyl methacrylate) (PMMA) as a matrix. The study revealed that the introduction of carbazole units onto the coumarin benzene ring led to compounds with thermally induced reverse intersystem crossing and delayed fluorescence. The study further demonstrated the potential utility of these compounds in practical applications by incorporating them into a Cmr‐PMMA‐based sensor for molecular oxygen detection. The resulting sensor exhibited promising performance, highlighting the adaptability and efficacy of the synthesized TADF‐carbazole‐coumarin compounds for reversible molecular oxygen sensing.

Published: July 2024

Abstract1D nanomaterials have attracted great attention due to their outstanding anisotropic and linear structures. A facile method is developed to fabricate 1D copper metal–organic framework nanowires (Cu‐MOF‐NW) through steam‐assisted conversion from Cu‐MOF precursors. During the steam‐assisted conversion, Cu‐MOF precursor gradually dissolves in methanol steam, and then recrystallized into Cu‐MOF‐NW, which shows high aspect ratio of about 600 and identical crystal structure of MOF‐74. As‐prepared Cu‐MOF‐NW with multiscale porous structure can effectively remove cationic dyes even in dye mixture. Moreover, Cu‐MOF‐NW, as an ideal template, is calcined to form Cu nanoparticle‐doped carbon nanofiber with maintaining its 1D morphology, which shows excellent electrocatalytic activity for the non‐enzymatic sensing of glucose.
