Multiple‐Text Comprehension and Evaluation: The Influence of Reading Goal, Belief Consistency, and Argument Type
Authors: Savvidou Sylvia M. , Diakidoy Irene‐Anna , Mason Lucia 
Published: August 2024

ABSTRACTThe present study examined how argument type (science based vs. personal case based), belief consistency (belief consistent vs. inconsistent) and reading goals (read to evaluate vs. read to learn) influence comprehension and trustworthiness evaluations for claim‐conflicting multiple texts. Undergraduates read four conflicting texts about the effects of vegan nutrition and completed four corresponding single‐text comprehension and trustworthiness tasks before completing a multiple‐text comprehension task. The results indicated better memory for personal case‐based texts that capitalized on everyday life experiences and emotions than science‐based texts in the multiple‐text comprehension task. Reading to evaluate benefitted memory only for the belief‐inconsistent personal text and contributed to lower trustworthiness ratings for all texts in comparison to reading to learn. The present study's findings highlight the importance of factors pertaining to argument quality, namely argument type, in comprehension and trustworthiness judgments.
Practical measures of science teacher learning: Conceptualizing organizational functions and affordances
Authors: Anderson Eleanor R. , Richards Jennifer 
Published: August 2024

AbstractIn this paper, we build on a growing body of research on practical measurement for educational improvement, contributing a conceptualization of the organizational functions of measurement in processes of persistence and change. Our work is grounded in theoretical understandings of micro‐institutional change that foreground processes of reproduction and disruption of organizational categories, priorities, assumptions, and practices. Drawing together measurement discourses from multiple fields of study, we identify four metaphors for organizational functions that measures can serve: carriers, windows, exercises, and drivers. We propose a conceptual framework illustrating relationships and pathways among these functions as they operate in context. We then apply the framework in the context of co‐designing three practical measures of science teacher learning in a large urban district, illustrating varied pathways through which the practical measures seemed to function, and documenting their respective affordances and constraints in driving reproduction and/or disruption in the organization's work to support science teacher learning. This line of work extends prior research on practical measurement through its focus on measures of science teacher learning and its attention to how practical measures can function to shape broader processes of organizational transformation and stability. This paper is part of the special issue on Teacher Learning and Practice within Organizational Contexts.

Authors: Donkor Mary , Kong Yusheng , Manu Emmanuel K. 
Published: August 2024

AbstractThis study examines the quest for environmental sustainability in Africa by analyzing the roles of natural resource abundance, governance quality, and government expenditure. It explores the relationships between these variables, employing the N‐shaped hypothesis across 42 African countries from 1986 to 2020 grouped into resource‐rich and resource‐poor countries. Utilizing the Lewbel 2SLS modeling technique, the research evaluates how these factors interact and impact carbon and nitrous emissions in the region. The findings reveal distinct patterns: resource‐poor countries exhibit an N‐shaped relationship between natural resource abundance and emissions. In contrast, resource‐rich countries show such patterns between government expenditure and carbon emissions. Moreover, in resource‐rich countries, higher natural resource abundance, government expenditure, and governance effectiveness tend to increase carbon emissions but decrease nitrous emissions. Conversely, in resource‐poor economies, carbon emissions decrease with natural resource abundance and governance quality but increase with government expenditure and effectiveness. Additionally, regulatory quality positively correlates with nitrous emissions across all contexts. The study's insights offer valuable guidance for policymakers aiming to foster environmental sustainability, emphasizing tailored strategies based on the diverse impacts of natural resources, governance, and government spending across different economic contexts.

AbstractThe nanoconfinement approach for constructing ultra‐small nanoparticles has been effectively utilized in the development of non‐precious metal catalysts. Herein, the catalyst precursor was prepared by host‐guest assembly method, using PCN‐222 as the host and 1,1′‐bis(diphenylphosphino) ferrocene (DPPF) as the guest. After calcination, the sub‐2 nm iron oxide nanoparticles within a phosphorus‐nitrogen co‐doped carbon matrix (Fe3O4@P/N‐CDCM) was obtained. Benefiting from the nanoconfinement effect, the sub‐2 nm Fe3O4 nanoparticles were uniformly dispersed on the P/N‐CDCM matrix. As a representative application, Fe3O4@P/N‐CDCM‐600 showed remarkable catalytic activity in the reduction of various nitroaromatic compounds. Under ambient conditions, the efficient reduction of nitro compounds in aqueous solution led to excellent conversion rates (96–99 %) and selectivity (99 %) within 45 minutes. Additionally, the catalyst maintained high efficiency over 5 cycles without experiencing a noticeable decrease in activity. This work provides an innovative and cost‐effective strategy for fabricating highly dispersed non‐precious metal nanoparticles.

Published: August 2024

AbstractBacterial infections tend to cause a series of cytopathic reactions and have become a major threat to human life. Among them, phenolic compounds are widely used as a natural antibacterial derivative for antifouling and antibacterial applications. In this study, four phenolic hydroxyacrylamide monomers have been successfully prepared using capsaicinoid derivatives as inspiration (named as OHABA, PHABA, AHMA, and AMTHBA, respectively) and the chemical structures were confirmed by FT‐IR, 1H‐NMR, 13C‐NMR. The minimum inhibitory concentration (MIC) assay and plate antibacterial assay were measured to explore the antibacterial properties of the monomer. The results showed that four capsaicin derivatives exhibited antibacterial activity, and the antibacterial properties of the four monomers from strong to weak were PHABA, OHABA, AHMA and AMTHBA. The best antibacterial activity was PHABA (MIC for E. coli: 1.6 mg/mL, bacteriostasis rate: 82.46 %, MIC for S. aureus: 1.6 mg/mL, bacteriostasis rate: 69.58 %). Both the cluster effect of monomers and the spatial distribution of phenolic hydroxyl groups in the structure of derivatives affect the antibacterial properties.

Published: August 2024

AbstractA new metallohybrid silsesquioxane (S) was synthesized herein from copper and ferricyanide via a cyanide bridge to produce a new electroactive hybrid material (SCuH), which was then characterized by spectroscopic and microscopic techniques and cyclic voltammetry. The voltammetric behavior of SCuH employing a graphite paste electrode indicates a well‐defined redox couple with formal potential Eθ′=0.76±0.01 V. The electrode exhibited high sensitivity to nitrite and was successfully tested for nitrite detection. The linearity of the analytical curve was 2.0×10−4 mol L−1 − 1.0×10−3 mol L−1, with a limit of detection of 2.65×10−5 mol L−1, and sensitivity amperometric value of 57.63 mA/mol L−1. These findings suggest that this material displays exceptional potential for application in electrochemical sensors designed for nitrite detection.

Published: August 2024

AbstractStaphylococcus epidermidis is a particular concern due to its high resistance to most antibiotics. We designed and synthesised a series of nitrofuran derivatives based on the chemical structure of nitrofurantoin. Among these derivatives, compared to nitrofurantoin, the nitrofuran derivatives with n‐alkyl groups did not effectively inhibit S. aureus with minimum inhibitory concentrations (MIC) values ranging from 16 to >128 μM, while these with benzyl groups displayed potent antibacterial activity against S. aureus with MIC values ranging from 4 to 16 μM. It suggests benzyl groups play an important role in the nitrofuran derivatives against S. aureus. The nitrofuran derivatives with benzyl groups also displayed potent antibacterial activity against S. epidermidis with MIC values ranging from 2 to 8 μM. Especially, compound 20 exhibited MIC 2 μM (0.814 μg/mL) against S. epidermidis. The CC50s of compound 20 in 293 T cells and LX‐2 cells were 3.131 μg/mL and 30.51 μg/mL, respectively. While at 128 μg/mL of compound 20, no obvious red blood cell rupture was observed. It showed minimal cytotoxicity and hemolytic activity. These findings suggest that compound 20 could function as a potential antibacterial agent for treating Urinary tract infections (UTIs) caused by S. epidermidis.

Published: August 2024

AbstractVideo‐rate atomic force microscopy (AFM) is used to record the near‐surface nanostructure and dynamics of one pure ionic liquid (IL), 1‐hexyl‐3‐methylimidazolium tris(pentafluoroethyl)trifluorophosphate (HMIM FAP), and a locally‐concentrated IL comprising HMIM FAP with the low viscosity diluent 1,1,2,2‐tetrafluoroethyl 2,2,2‐trifluoroethyl ether (TFTFE), on highly oriented pyrolytic graphite (HOPG) and Au(111) electrodes as a function of potential. Over the potential range measured (open‐circuit potential ± 1 V), different near‐surface nanostructures are observed. For pure HMIM FAP, globular aggregates align in rows on HOPG, whereas elongated and worm‐like nanostructures form on Au(111). For 2:1 (wt:wt) HMIM FAP:TFTFE, larger and less defined diluent swollen IL aggregates are present on both electrodes. Long‐lived near‐surface nanostructures for HMIM FAP and the 2:1 (wt:wt) HMIM FAP:TFTFE persist on both electrodes. 2:1 (wt:wt) HMIM FAP:TFTFE mixture diffuses more rapidly than pure HMIM FAP on both electrodes with obviously higher diffusion coefficients on HOPG than on Au(111) due to weaker electrostatic and solvophobic interactions between near‐surface aggregates and Stern layer ions. These outcomes provide valuable insights for a wide range of IL applications in interface sciences, including electrolytes, catalysts, lubricants, and sensors.

AbstractPlatinum‐Ruthenium (PtRu) bimetallic nanoparticles are promising catalysts for methanol oxidation reaction (MOR) required by direct methanol fuel cells. However, existing catalyst synthesis methods have difficulty controlling their composition and structures. Here, a direct Joule heating method to yield highly active and stable PtRu catalysts for MOR is shown. The optimized Joule heating condition at 1000 °C over 50 microseconds produces uniform PtRu nanoparticles (6.32 wt.% Pt and 2.97 wt% Ru) with an average size of 2.0 ± 0.5 nanometers supported on carbon black substrates. They have a large electrochemically active surface area (ECSA) of 239 m2 g−1 and a high ECSA normalized specific activity of 0.295 mA cm−2. They demonstrate a peak mass activity of 705.9 mA mgPt−1 for MOR, 2.8 times that of commercial 20 wt.% platinum/carbon catalysts, and much superior to PtRu catalysts obtained by standard hydrothermal synthesis. Theoretical calculation results indicate that the superior catalytic activity can be attributed to modified Pt sites in PtRu nanoparticles, enabling strong methanol adsorption and weak carbon monoxide binding. Further, the PtRu catalyst demonstrates excellent stability in two‐electrode methanol fuel cell tests with 85.3% current density retention and minimum Pt surface oxidation after 24 h.

Published: August 2024

AbstractEnergy storage has become increasingly crucial, necessitating alternatives to lithium‐ion batteries due to critical supply constraints. Aqueous multivalent metal‐ion batteries (AMVIBs) offer significant potential for large‐scale energy storage, leveraging the high abundance and environmentally benign nature of elements like zinc, magnesium, calcium, and aluminum in the Earth's crust. However, the slow ion diffusion kinetics and stability issues of cathode materials pose significant technical challenges, raising concerns about the future viability of AMVIB technologies. Recent research has focused on nanoengineering cathodes to address these issues, but practical implementation is limited by low mass‐loading. Therefore, developing effective engineering strategies for cathode materials is essential. This review introduces the 3D printing‐enabled structural design of cathodes as a transformative strategy for advancing AMVIBs. It begins by summarizing recent developments and common challenges in cathode materials for AMVIBs and then illustrates various 3D‐printed cathode structural designs aimed at overcoming the limitations of conventional cathode materials, highlighting pioneering work in this field. Finally, the review discusses the necessary technological advancements in 3D printing processes to further develop advanced 3D‐printed AMVIBs. The reader will receive new fresh perspective on multivalent metal‐ion batteries and the potential of additive technologies in this field.

Published: August 2024

AbstractApplication of an aqueous Zn‐ion battery is plagued by a water‐induced hydrogen evolution reaction (HER), resulting in local pH variations and an unstable electrode–electrolyte interface (EEI) with uncontrolled Zn plating and side reactions. Here, 4‐methyl pyridine N‐oxide (PNO) is introduced as a redox non‐innocent additive that comprises a hydrophilic bipolar N+–O− ion pair as a coordinating ligand for Zn and a hydrophobic ─CH3 group at the para position of the pyridine ring that reduces water activity at the EEI, thereby enhancing stability. The N+–O− moiety of PNO possesses the unique functionality of an efficient push electron donor and pull electron acceptor, thus maintaining the desired pH during charging/discharging. Intriguingly, replacing ─CH3 (electron pushing +I effect) by ─CF3 group (electron pulling ─I effect), however, does not improve the reversibility; instead, it degrades the cell performance. The electrolyte with 2 m ZnSO4 + 15 mm PNO enables symmetric cell Zn plating/stripping for a remarkable > 10 000 h at 0.5 mA cm−2 and exhibits coulombic efficiency (CE) ≈99.61% at 0.8 mA cm−2 in Zn/Cu asymmetric cell. This work showcases the immense interplay of the electron push–pull of the additives on the cycling.

AbstractIncreasing climate‐related extreme weather events and conflicts hinder safe water sanitation for vulnerable populations. In developing areas, centralized water systems are impractical due to high costs and poor infrastructure. Thus, technologies utilizing renewable energy like solar and mechanical energy for water treatment hold promise. It is critical to develop photocatalysts and piezoelectric/triboelectric catalysts that capture solar energy as well as mechanical energy to generate disinfectants to maximize energy utilization. The latest advancements in principles, materials, and processes utilizing solar and mechanical energy for water disinfection are highlighted in this review. First, we elucidate both direct and indirect mechanisms of sunlight‐mediated water disinfection, discuss the evolution of photocatalysts from simple UV absorption to visible‐light utilization, and even near‐infrared light exploitation to enhance solar spectrum utilization efficiency. Furthermore, we delve into the fundamental principles of piezoelectricity and triboelectricity relying on mechanical energy conversion as well as summarize the development of piezo/triboelectric catalysts from being driven by high‐frequency energy to utilizing low‐frequency mechanical energy from the environment. Finally, challenges and directions for efficient systems are outlined to inspire rational design strategies and accelerate the production of superior catalytic systems applicable across a broad range.

ABSTRACTAluminum oxide nanoparticles (Al2O3 NPs) are among the most extensively utilized nanoparticles in nanotechnology and that have negative impacts on the environment. Therefore, the intention of this work is to investigate the protective and therapeutic effects of curcumin in nanoform (Cur NPs) against Al2O3 NPs induced kidney toxicity, oxidative stress, DNA damage, and changes in necrosis factor alpha (TNFα) and proliferating cell nuclear antigen (PCNA) expressions in male rats. Fifty healthy adult male were divided into five groups [G1, control; G2, received 50 mg/kg/day for 4 weeks of Cur NPs orally; G3, received 6 mg/kg BW orally for 4 weeks of Al2O3 NPs; G4, (Cur NPs + Al2O3 NPs) received Cur NPs and Al2O3 NPs at a dose similar to G2 and G3, respectively for 4 weeks; G5, (Al2O3 NPs + Cur NPs) received Al2O3 NPs at a dose similar to G3 for 4 weeks then received Cur NPs at a dose similar to G2 for another 4 weeks]. Current results revealed that Al2O3 NPs induced a significant elevation in serum urea, creatinine, chloride, calcium, kidney malondialdehyde (MDA), DNA damage, injury, TNFα and PCNA expressions and a significant depletion in serum potassium, kidney superoxide dismutase (SOD), glutathione (GSH) as compared to control. On the other hand, treatments of Al2O3 NPs with Cur NPs induced modulation in all altered parameters and improved kidney functions and structure, with best results for the Al2O3 NPs + Cur NPs than Cur NPs + Al2O3 NPs. In conclusion, Cur NPs has the capacity to mitigate the renal toxicity induced by Al2O3 NPs in male albino rats.
