Published: October 2024

AbstractVarious strategies are developed to engineer aligned hierarchical architectures in polymer hydrogels for enhanced mechanical performance. However, chain alignment remains impeded by the presence of hydrogen bonds between adjacent chains. Herein, a facile sacrificial micelle‐assisted‐alignment strategy is proposed, leading to well‐aligned, strong and tough pure chitosan hydrogels. The sacrificial sodium dodecyl sulfate micelles electrostatically interact with the protonated chitosan chains, enabling chain sliding and alignment under uniaxial forces. Subsequently, sacrificial micelles can be easily removed via NaOH treatment, causing the reforming of H‐bond in the chain networks. The strength of the pure chitosan hydrogels increases 140‐fold, reaching 58.9 ± 3.4 MPa; the modulus increases 595‐fold, reaching 226.4 ± 42.8 MPa. After drying‐rehydration, the strength and modulus further rise to 70.3 ± 2.4 and 403.5 ± 76.3 MPa, marking a significant advancement in high‐strength pure chitosan hydrogel films. Furthermore, the designed multiscale architectures involving enhanced crystallinity, well‐aligned fibers, strong interfaces, robust multilayer Bouligand assembly contribute to the exact replica of lobster underbelly with impact resistance up to 6.8 ± 1.0 kJ m−1. This work presents a promising strategy for strong, tough, stiff and impact‐resistant polymer hydrogels via well‐aligned hierarchical design.

AbstractEndometriosis is a prevalent gynecological condition characterized by chronic pelvic pain, dysmenorrhea, and infertility, affecting ≈176 million women of reproductive age worldwide. Current treatments, including pharmacological and surgical interventions, are often associated with significant side effects and high recurrence rates. Consequently, there is an urgent need for innovative and safer therapeutic approaches. In this study, an injectable magnetic hydrogel nanosystem is developed designed for the dual‐purpose magnetothermal and anti‐inflammatory treatment of endometriosis. This hydrogel incorporates Fe3O4 nanoparticles alongside an anti‐inflammatory peptide. Upon magnetic activation, the Fe3O4 nanoparticles induce a localized hyperthermic response, raising the temperature of endometriotic lesions to 63.3 °C, effectively destroying endometriotic cells. Concurrently, the thermally responsive hydrogel facilitates the controlled release of the anti‐inflammatory peptide, thus modulating the inflammatory milieu. The biocompatibility and complete in vivo degradability of the hydrogel further enhance its therapeutic potential. The in vivo studies demonstrated that this injectable magnetic hydrogel system achieved a 90% reduction in the volume of endometriotic lesions and significantly decreased inflammatory markers, offering a promising non‐invasive treatment modality for endometriosis. By integrating precise lesion ablation with the modulation of the inflammatory microenvironment, this system represents a novel approach to the clinical management of endometriosis.

AbstractMg metal anode‐based battery is a more sustainable, lower cost, and higher energy density alternative to Li‐ion. However, this battery chemistry also faces several challenges associated with the high charge density of Mg2+, including achieving high reversibility and low voltage hysteresis for Mg metal plating/stripping. While significant improvements are achieved in last decades, they involve rather complex electrolyte formulations and/or Mg salts difficult to produce, and the use of unpractical substrates such as platinum. Here, significant improvement in terms of Mg plating kinetics is achieved in electrolytes containing commercial magnesium bis(trifluoromethanesulfonyl)imide salt (Mg(TFSI)2) by using titanium substrate with similar crystal structure and lattice parameter as Mg leading to lower nucleation overpotential. Low salt concentration electrolyte and addition of dibutyl magnesium (Mg(butyl)2) also enable the formation of thinner interphase, richer in solvent based decomposition products, further improving Mg plating kinetics. This work highlights the complex role of Mg(butyl)2, often considered as a simple drying agent, and how it impacts ion solvation favoring the mobility of electroactive cationic species, paving the way toward better electrolyte design with improved cation transference number.

AbstractTriboelectric nanogenerator (TENG), as a new technique for energy capture, has unique advantages in harvesting high‐entropy energy. In view of the wind‐induced vibration characteristics of power transmission lines, the symmetric elastic bistable triboelectric nanogenerator (EB‐TENG) is introduced in this work. The core component of the EB‐TENG is the elastic bistable cantilever beam structure, which is designed by introducing an elastic perturbation structure to the conventional cantilever beam. This beam results in several sub‐resonance frequencies in addition to the natural frequencies, which broadens the frequency band of the EB‐TENG. In addition, the EB‐TENG adopts a symmetrical cantilever beam to ensure effective harvesting of vibration energy, even in situations of self‐tilting and external tilting vibration. The experimental outcomes confirm that the EB‐TENG can significantly harvest vibration energy in the 7–60 Hz frequency range and delivers the maximum peak power of 2.846 mW, which meets the major vibration frequency range of power transmission lines under the action of breeze. Finally, self‐powered strategy based on EB‐TENG online monitoring devices (such as tower obstruction lights, temperature and humidity sensors, and line high temperature wireless alarms) is constructed. This work helps promote the application of in‐situ self‐powered monitoring based on TENG in smart transmission lines.

ABSTRACTIntroductionUniversity students experienced significant changes in their routines with the implementation of remote learning during Covid‐19 pandemic, including increase in sedentary behavior (SB) time and ultra‐processed foods (UPF's) consumption, which may have influenced changes in body mass index (BMI).ObjectiveTo evaluate the association between the variation in SB time and UPF's consumption with the variation in BMI, before and during the pandemic, in university students.MethodsThis is a cross‐sectional study, conducted between November 2020 and February 2021, with students from a public university of Southeast of Brazil, who answered an online questionnaire with questions regarding to the period before and during the pandemic. SB was assessed through questions about time spent on TV and electronic devices. A score of the frequency of UPF's consumption was estimated based on the Brazilian Food Guide. Self‐reported information on height and body mass was used to calculate BMI.ResultsThe sample comprised 3390 university students, with an average age of 28.7 (± 10.0) years. Among them, 65.4% were undergraduates, and 66.9% were women. SB time, UPF score, and BMI increased significantly during the pandemic, compared to the previous period. In this population, there was a significant association between increased SB time (β = 0.06; SE = 0.01; p < 0.001) and UPF score (β = 0.08; SE = 0.01; p < 0.001) with an increase in BMI.ConclusionChanges in SB time and UPF score were associated with an increase in BMI before and during the COVID‐19 pandemic in students from a Brazilian University.

AbstractIntroductionDiagnosis of empty nose syndrome (ENS) relies on the ENS six‐item questionnaire (ENS6Q) with a score of ≥11, followed by a “positive” cotton test yielding seven‐point reduction from baseline ENS6Q score via cotton placement to the inferior meatus (IM). Given the intricacies of diagnosing ENS and the propensity for false positives with the standard cotton test, we modified the classic single‐step cotton test into a four‐part Stepwise Empty Nose Syndrome Evaluation (SENSE) cotton test to reduce bias and evaluate the placebo effect.MethodsIndividuals diagnosed with ENS underwent the SENSE test, a single‐blinded, four‐step, office‐based cotton test, without topical anesthesia or decongestants. Conditions included: (1) placebo/no cotton placed; (2) complete cotton‐blockade of nasal vestibule; (3) cotton placed medially against the nasal septum; and (4) cotton placed laterally in the IM (site of inferior turbinate tissue loss). With each condition, patients completed an ENS6Q.ResultsForty‐eight ENS patients were included. Twenty‐nine percent demonstrated a placebo effect (p < 0.001), 40.4% had a positive response to complete cotton‐blockade (p < 0.001), 64.4% to septum‐placed cotton, and 79.1% to IM‐placed cotton (p < 0.001), corresponding to a mean ENS6Q reduction of 11.9 points (p < 0.001). Notably, the mean difference in ENS6Q scores between septum and IM placement was 1.7 (p < 0.001).ConclusionsThe SENSE test offers further insight into subtleties of nasal breathing experienced by ENS patients. The placebo effect can be prominent and important to consider with individual patients. While most ENS patients prefer any intranasal cotton placement over baseline, blinded testing reveals these patients can accurately discriminate minimal changes in nasal aerodynamics.

Published: October 2024

AbstractThe development of bifunctional photogenerated carrier‐assisted electrocatalytic (PCA‐EC) electrodes that operate with stability at large current‐density remains a significant challenge. Herein, we demonstrate a simple sputtering‐deposition process to synthesize a novel MnWO4/FeCoNi Mott‐Schottky heterojunction coating and deposit it on a pure Ti substrate to prepare high‐performance PCA‐EC electrodes, which exhibits enhanced light absorption range/intensity and rapidly separated photogenerated electron‐hole pairs. This design allows photogenerated electrons to directly participate in the hydrogen evolution reaction (HER), while the strong oxidation of photogenerated holes significantly reduces the defect formation energy of active metals, thereby facilitating the rapid reconstruction of highly active Ni(FeCo)OOH/MnOOH species for the oxygen evolution reaction (OER). As expected, the as‐prepared electrode demonstrates the overpotentials of 64 mV for the HER and 204 mV for the OER at 10 mA cm−2 under illumination. Benefiting from the stable interface with Fe/Co/Ni‐O−Mn/W bonding units, the dual‐electrode photoassisted electrolytic cell achieves long‐term stability at current densities of 500 and 1000 mA cm−2. This work provides detailed insights into the enhancement mechanism of PCA‐EC and contributes to the development of photo‐assisted water splitting electrodes for large current‐density applications.

Published: October 2024

AbstractPhotoelectrochemical (PEC) water splitting represents a promising approach for harnessing solar energy and transforming it into storable hydrogen. However, the complicated 4‐electron transfer process of water oxidation reaction imposes kinetic limitations on the overall efficiency. Herein, we proposed a strategy by substituting water oxidation with the oxidation of ethylene glycol (EG), which is a hydrolysis byproduct of polyethylene terephthalate (PET) plastic waste. To achieve this, we developed and synthesized BiVO4/NiCo‐LDH photoanodes capable of achieving a high Faradaic efficiency (FE) exceeding 85 % for the oxidation of EG to formate in a strongly alkaline environment. The reaction mechanism was further elucidated using in situ FTIR spectroscopy. Additionally, we successfully constructed an unassisted PEC device for EG oxidation and hydrogen generation by pairing the translucent Mo : BiVO4/NiCo‐LDH photoanode with a state‐of‐the‐art Cu2O photocathode, resulting in an approximate photocurrent density of 2.3 mA/cm2. Our research not only offers a PEC pathway for converting PET plastics into valuable chemicals but also enables simultaneous hydrogen production.

ABSTRACTThe primary objective of this study was to explore the synthesis of novel dihydrocyclopenta[b]pyrrole derivatives with a high degree of efficiency. The work utilized a nanocatalyst composed of Ag/Fe3O4@MWCNTs in a multicomponent reaction including vinilydene aldehydes, ethyl 2‐amino‐4‐dioxo‐4‐arylbutanoates, and alkyl bromides. The reaction was carried out in aqueous solution at ambient temperature, leading to the formation of novel chemicals. The produced compounds exhibit antioxidant activity as a result of the evaluation processes performed on their NH group. Furthermore, an evaluation was performed on the antibacterial effectiveness of newly produced pyridines using a disk diffusion technique, utilizing two different strains of Gram‐negative bacteria. Significantly, the substances that were evaluated shown inhibitory effects on the development of Gram‐positive bacteria as well. This method has several benefits, including quick response times, high product yields, and easy separation of catalyst and product through simple procedures.

AbstractDutch secondary education is a multi‐tiered system, and many students are placed in a single track in the first year (seventh grade) of secondary education. As part of the placement procedure, all sixth‐grade students take an end of primary school test. Although these standardised attainment tests (SATs) are considered high‐stakes tests, the predictive accuracy of many of these SATs has not been studied comprehensively. In the current study, three SATs commonly used in The Netherlands (CET, IEP and R8) were compared on their predictive accuracy of educational attainment in ninth grade. The predictive accuracy was also investigated for particular track recommendations, using multiple cohorts of population data, each of around 160,000 students. For the two most recent cohorts, CET was overall a more accurate predictor of educational attainment in ninth grade than R8, which in turn was a more accurate predictor than IEP. All three attainment tests had only mediocre to acceptable predictive power overall. Furthermore, all three tests had very poor predictive power for certain single‐track recommendations. For these track recommendations, many students attained a lower or higher educational level in ninth grade. This study is the first to compare the predictive accuracy of these SATs. While statistical noise is normal when using tests, since different tests are used that vary widely in predictive accuracy, there is much more noise than is acceptable. As long as the predictive accuracy is poor to mediocre, these SATs should not have a large role to play in the Dutch placement procedure for secondary education.

AbstractProfessional learning for quality teaching is a lifelong enterprise. Nevertheless, it entails a considerable cost with varying outcomes. Drawing on Snyder's hope theory and Pantic's teacher agency, this paper aims to present a model aimed at deepening our understanding of teachers' intentions and competencies in inclusive education. The model formulates a professional learning cycle tailored to address their unique needs. This study draws on data from a larger qualitative dominant mixed‐methods study exploring 18 teachers' professional learning experience with the inclusionEd online platform. The process involved a pre‐training online survey and interviews and employed multiple strategies for data analysis. Descriptive statistics were used for pre‐training survey data to assess teacher‐participants' attitudes towards inclusion and efficacy levels in this area. Subsequently, using Snyder's hope theory and Pantic's teacher agency, we deductively analysed interview data. The quantitative results showed that teacher‐participants had positive beliefs about inclusive education with high efficacy. However, qualitative data analysis uncovered a misalignment between their stated beliefs and enacted beliefs, revealing diverse pathways to both success and challenges in their implementation of inclusive practices. The qualitative analysis, combined with the preliminary survey findings, unveiled the fluidity of hope and identified the influences on shifting hope and maintaining a positive stance. We offer an illustration of teacher professional learning pathways. Understanding how these pathways might be used to increase the value and outcomes of professional learning programmes is discussed. This study concludes with a discussion of theoretical and practical implications and directions for future research.

AbstractBei gekrümmten Stahlbetonbauteilen resultieren aus den Stahlzugkräften der Bewehrung radial gerichtete Umlenkspannungen im Beton, die das Abplatzen der Betondeckung und das Herausziehen der Bewehrungsstäbe provozieren können. Zur Untersuchung der Aufnahme dieser Umlenkkräfte durch den Beton wurde an der FH Münster der Einfluss von verschiedenen Parametern auf die Ausbruchkräfte von Bewehrungsstäben ermittelt. Dabei wurde sowohl der Einfluss von unterschiedlichen Stabdurchmessern (16, 20, 25, 28 und 32 mm) als auch der Einfluss der Interaktion zwischen mehreren Bewehrungsstäben bei zwei unterschiedlichen Betonrezepturen untersucht. Das Ergebnis dieser Versuche ist, dass größere Bewehrungsstabdurchmesser sowie eine höhere Betongüte i. A. höhere Bruchlasten generierten.

AbstractLanthanum oxide was successfully synthesized by hydrothermal method by varying the reaction time such as 6, 12, and 24 h. In XRD, study confirms the presence of a hexagonal structure, and the phase remains the same at different times; the main goal is to assess the average crystallite size of prepared La2O3 nanoparticles, which was found in the range of 6 to 8 nm. An interesting observation from the XRD data was the apparent increase in crystalline nature as the synthesis time was extended. The UV–Vis spectroscopic studies show a change in the band gap when the reaction time is changed. The morphology analysis shows that the image revealed that the particles formed were agglomerated and formed a spherical shape, with diameters ranging between 35 and 86 nm. When tested for photocatalytic activity, the La2O3 nanoparticles show a degradation of methylene blue dye when the time varies. Remarkably, the nanoparticles synthesized exhibited a profound ability to degrade the dye, with an efficiency rate hitting as high as 89% under halogen light illumination.
