Structural Modulation in Viologen‐Based Ionic Porous Organic Polymers for Catalytic Non‐Redox CO2 Fixation
Authors: Lodh Tapolabdha , Shreeraj G. , Patra Abhijit 
Published: January 2025

AbstractThe rational design of metal‐free, porous, and heterogeneous catalysts with large specific surface areas for efficient CO2 capture and utilization has remained a significant challenge. In this study, two structurally distinct viologen‐based novel ionic porous organic polymers (iPOPs) featuring a triazine core are developed, employing different polymerization methods to modulate their porosity and catalytic properties. The alkyne‐linked SC‐iPOP, synthesized through Sonogashira polycondensation, exhibits high porosity (specific BET surface area: 616 ± 9 m2 g−1) over BHC‐iPOP with secondary amine linkages fabricated by Buchwald‐Hartwig polymerization. SC‐iPOP demonstrates superior catalytic efficiency in the metal‐free cycloaddition of CO2 with epoxides to form cyclic organic carbonates under atmospheric pressure and solvent‐free conditions, with excellent recyclability. This enhanced catalytic performance, compared to BHC‐iPOP, is attributed to the high porosity of SC‐iPOP and the presence of abundant CO2‐philic ionic active sites. The current study emphasizes the role of structural modifications in designing efficient porous catalysts for metal‐free CO2 fixation.
The Impact of Technological Diversification on Innovation Performance: The Moderating Effects From an Agency Perspective
Authors: Zhan Xinrui , Liu Yunqing , Zhao Xingxin 
Published: January 2025

ABSTRACTIn the rapidly advancing digital era, technological diversification (TD) emerges as a pivotal strategy to enhance firms' innovation performance. This study explores the nonlinear dynamics of TD and innovation performance, positing an inverted U‐shaped relationship and examining the moderating effects of governance mechanisms—management shareholding, board size, board meeting frequency, and analyst coverage—from the perspectives of incentive mechanism design, internal control, and external regulation. Using a comprehensive panel dataset of 11,036 firm‐year observations from 1438 Chinese listed manufacturers (2012–2020), we employ Tobit regression to validate our hypotheses. Our findings confirm the inverted U‐shaped relationship between TD and innovation performance, which is significantly moderated by governance mechanisms that mitigate agency costs. The results withstand a battery of robustness checks and address endogeneity concerns. By integrating agency theory into the analysis of TD, this study provides a novel perspective and actionable strategies for firms to optimize TD within sustainable boundaries, ultimately achieving long‐term innovation growth.

ABSTRACTThis paper aims to address an interesting open problem, posed in the paper “Singular Optimal Control for a Transport‐Diffusion Equation” of Sergio Guerrero and Gilles Lebeau in 2007. The problem involves studying the null controllability cost of a transport–diffusion equation with Neumann conditions, where the diffusivity coefficient is denoted by and the velocity by . Our objective is twofold. First, we investigate the scenario where each velocity trajectory originating from enters the control region in a shorter time at a fixed entry time. By employing Agmon and dissipation inequalities, and Carleman estimate in the case is the gradient of a time‐dependent scalar field, we establish that the control cost remains bounded for sufficiently small and large control time. Secondly, we explore the case where at least one trajectory fails to enter the control region and remains in . In this scenario, we prove that the control cost explodes exponentially when the diffusivity approaches zero and the control time is sufficiently small for general velocity.

AbstractBackgroundNovel motion‐compensated treatment techniques on the MR‐linac can address adverse intra‐fraction motion effects. These techniques involve beam gating or intra‐fraction adaptations of the treatment plan based on real‐time magnetic resonance imaging (MRI) performed during treatment. For quality assurance (QA) of these workflows, a multi‐purpose motion platform is desirable. This platform should accommodate various phantoms, enabling multiple QA workflows.PurposeThis study aims to evaluate the new IBA QUASAR Motion MR Platform for use in the 1.5 T MR‐linac.MethodsThe motion platform was assessed for several magnetic resonance (MR) characteristics, including spurious noise generation and B0&B1 homogeneity. In addition, the motion platform's motion accuracy and beam attenuation were assessed. An application was shown with a ScandiDos Delta4 Phantom+ MR demonstrating patient‐specific plan QA of gated treatments using time‐resolved dosimetry that includes motion based on a patient's respiratory motion trace.ResultsAll MR characterization measurements were within the set tolerances for MRI QA. The motion platform motion accuracy showed excellent agreement with the reference, with a standard deviation of the amplitude of 0.01 mm (20 kg load) for the motor's self‐estimated positions and 0.22 mm (no load) for the images acquired with the electronic portal imager. Beam attenuation was found to be 11.8%. The combination of the motion platform and Delta4 demonstrated motion‐included dosimetry at high temporal and spatial resolutions. Motion influenced the measured dose in non‐gated treatments by up to −20.1%, while gated deliveries showed differences of up to −1.7% for selected diodes.ConclusionThe motion platform was found to be usable in a 1.5 T magnetic field, and for all MR characterization experiments, no influence from the motion platform was observed. This motion platform enables to perform motion‐included QA, with a measurement device of choice.

AbstractObjectiveAdvances in the treatment of human papillomavirus (HPV)‐associated oropharyngeal squamous cell carcinoma (OPSCC) include transoral robotic surgery (TORS) and proton beam therapy (PBT). This study aims to improve understanding of the treatment toxicities associated with adjuvant PBT following TORS for OPSCC.Study DesignA retrospective review.SettingAn academic tertiary care center in Baltimore, Maryland.MethodsPatients undergoing TORS followed by adjuvant PBT from 2017 to 2023 were reviewed.ResultsForty‐seven patients with HPV‐associated OPSCC underwent TORS followed by adjuvant PBT. Forty‐one (87.2%) patients were male. The median age at first radiation fraction was 61.7 years. Forty‐one (87.2%) identified as white and 6 (12.8%) as African American. Most patients had T1 (23 [48.9%]) or T2 (22 [46.8%]), N1 (41 [87.2%]) disease. The majority (98.3%) of acute toxicities were grade 1 or 2, with only 1 (2.1%) patient developing grade 3 toxicities. Three (6.4%) patients required a feeding tube for nutrition during adjuvant proton radiation treatment. The 3 patients who required feeding tubes during radiation also required postoperative nasogastric tubes for a median of 16 days, compared with 3 days for all other patients (Mann–Whitney U, P = .02). The most common chronic toxicities included xerostomia, dysphagia, dysgeusia, and lymphedema, which decreased over time.ConclusionHPV‐associated OPSCC treated with TORS followed by adjuvant PBT demonstrated a favorable toxicity profile with mostly grade 1 or 2 acute toxicities. Feeding tube requirement during adjuvant PBT was low at 6.4%. Many chronic toxicities appeared to decrease in frequency with time from radiation, although further study is required.
Assessing the benefits of digital game‐based learning with Minecraft in children, adolescents and young adults: A broad systematic review

Published: January 2025

AbstractMinecraft is a popular digital game‐based learning (DGBL) tool used in learning environments around the world. With increasing emphasis on evidence‐informed practice and policymaking in educational systems, this paper systematically reviews the evidence base behind the use of Minecraft in improving academic, cognitive, motivational‐affective and social outcomes. We searched seven databases and other secondary sources up until February 2024. Pre‐post intervention studies that evaluated the use of Minecraft (randomised, non‐randomised and single‐group studies) in children, adolescents and young adults were included. Twenty‐nine studies satisfied our inclusion criteria. Studies primarily investigated Minecraft as a tool to improve cognitive (n = 7) and academic (n = 16) outcomes. Studies reported positive effects on spatial thinking (n = 2), creativity (n = 3), critical thinking (n = 1), mathematics (n = 5), science (n = 4) and language (n = 2). However, all studies included in this review had a medium or high risk of bias. Therefore, while Minecraft demonstrates good potential in improving these outcomes, effects need to be replicated in more rigorous studies. Suggestions for future research are discussed. This review provides timely evidence for educators, school leaders and policymakers regarding the use of DGBL with Minecraft.
A bibliometric and systematic review of literature on teacher educators during the times of neoliberal internationalisation
Authors: Nguyen Ngan Thi Lan 
Published: January 2025

AbstractThe neoliberal internationalisation of teacher education affects the professional lives of teacher educators in various ways. However, a comprehensive understanding of research on teacher educators during the times of neoliberal internationalisation has not been synthesised. This study reviews the literature on teacher educators within the context of neoliberal internationalisation through a combination of bibliometric and systematic approaches. Bibliometric data analysis with Biblioshiny in R and VOSviewer was employed to examine the literature's intellectual structure and research foci of 84 documents downloaded from the Scopus database. Additionally, the same documents were analysed thematically to enrich data from the bibliometric study. Firstly, findings revealed an imbalance in knowledge production and citation within the intellectual structure of literature. Secondly, seven themes from the word co‐occurrence network presented seven professional duties of teacher educators during neoliberal internationalisation including (1) teaching for social justice, (2) fostering global consciousness of student teachers and sustainability in internationalisation, (3) engaging in professional learning, (4) providing global competence education for student teachers, (5) addressing the technification of teacher education accelerated by the COVID‐19 pandemic, (6) integrating research into teaching, and (7) promoting (multi)cultural awareness in language teacher education. The complexity of teacher educators' professional lives calls for support and collaboration from stakeholders to enhance their resilience under the increasing influence of neoliberal internationalisation.
Untwisting Strategy of MOF Nanosheets in Ultrathin Film Membrane for High Molecular Separation Performance

Published: January 2025

AbstractOriented 2D metal‐organic framework (MOF) membranes hold considerable promise for industrial separation processes. Nevertheless, the lattice misalignment caused by the twisted stacking of 2D nanosheets reduces the in‐plane pore size and exerts a significant impact on the membrane separation performance. Precisely regulating the stacking pattern of oriented 2D MOF membranes remains a significant challenge. Here, a scalable scrape‐coating technique supplemented by a vapor untwisting strategy is proposed to directly construct non‐twisted and ultrathin Zr‐BTB membranes (Zr‐BTB‐M) on polyvinylidene fluoride (PVDF) substrates. The Zr‐BTB nanosheets are induced to undergo lattice reorganization during the coating process, resulting in highly overlapped lattices and the largest in‐plane pore channels. The exceptional butyl acetate selective adsorption capacity of non‐twisted Zr‐BTB, combined with its provision of highly ordered vertical penetrating pathways, significantly enhances molecular transport. After facile polydimethylsiloxane (PDMS) coating, the pervaporation separation index of the PDMS/Zr‐BTB‐M/PVDF membrane is found to be 9.74 times higher than that of conventional PDMS/PVDF membranes, paving the way for innovative, high‐efficiency, energy‐saving membrane separation technologies.

AbstractAs the age of the Internet of Things (IoTs) unfolds, along with the rapid advancement of artificial intelligence (AI), traditional von Neumann‐based computing systems encounter significant challenges in handling vast amounts of data storage and processing. Bioinspired neuromorphic computing strategies offer a promising solution, characterized by features of in‐memory computing, massively parallel processing, and event‐driven operations. Compared to traditional rigid silicon‐based devices, flexible neuromorphic devices are lightweight, thin, and highly stretchable, garnering considerable attention. Among the materials utilized in these devices, transition metal carbides/nitrides (MXenes) are particularly noteworthy materials with their excellent flexibility, exceptional conductivity, and hydrophilicity, which confer remarkable properties upon these devices. Herein, a comprehensive discussion is provided on the applications of MXenes in flexible memory and neuromorphic devices. This review covers the basic principles and device structures of memory and neuromorphic devices, common parameters and emerging materials of flexible devices, as well as the common synthesis, functionalization methods, and distinct properties of MXenes. The remaining challenges and future opportunities of MXenes in relevant devices are also presented. This review can serve as a valuable reference and lay a cornerstone for the practical and feasible implementation of MXenes in flexible memory and neuromorphic technologies.

AbstractLithium‐carbon dioxide (Li‐CO₂) batteries have attracted much attention due to their high energy density, low cost, and carbon sequestration. However, the sluggish conversion kinetics between CO₂ and the discharge product lithium carbonate (Li₂CO₃) have hindered their practical applications. Herein, a flower‐like photosensitive metal–organic framework (FJU‐115‐NS) has been employed as a cathodic electrocatalyst for Li‐CO₂ batteries. The FJU‐115‐NS with well‐ordered micropores and abundant exposed catalytic sites can effectively facilitate lithium ion transport and catalyze the Li₂CO₃ formation/decomposition, leading to improved battery performance. At a current density of 200 mA g⁻¹, the FJU‐115‐NS battery exhibits a substantial discharge capacity of 31579.34 mA h g⁻¹, a low overpotential of 1.31 V, and stable operation over 3200 h. Importantly, under light irradiation, the charging voltage significantly dropped from 4.45 V (without light) to 3.43 V at a high current density of 2 A g⁻¹. Additionally, the cell demonstrated an exceptionally low overpotential of just 0.45 V at a current density of 200 mA g⁻¹, highlighting its enhanced efficiency under light‐assisted conditions. This work provides valuable guidance for developing light‐assisted MOF catalysts to upgrade the longevity and energy efficiency of Li‐CO₂ batteries.

Published: January 2025

AbstractThe unique optical, electrical, and thermal properties of 1D nanowires have sparked significant interest in growing high‐quality 1D materials. Nanowire arrays and aligned growth offer scalability and maintain anisotropic properties, making them promising for research and applications. However, mass‐producing high‐quality nanowire arrays remains a challenge. A strategy is proposed for growing nanowire arrays based on homogeneous precursor as the substrate. Both calculations and experiments demonstrate that using a self‐assembly micro‐platform in advance facilitates epitaxial growth via chemical vapor deposition (CVD) to achieve highly oriented nanowire arrays. This is attributed to changes in crystallographic disregistry and adhesion energy. For instance, SnTe nanowire arrays are successfully grown using this method, with significantly lower thermal conductivity (≈5.5 W m−1 K−1 at 300 K) compared to the bulk material (≈9.1 W m−1 K−1 at 300 K), making them ideal for thermoelectric applications. The research lays the foundation for the tunable growth of IV–VI nanowire arrays and opens up possibilities for innovative thermoelectric nano–micro devices.

Published: January 2025

ABSTRACTAdolescence and pregnancy involve elevated levels of hormones (e.g., estrogen, androgen) during which exposure to endocrine disruptors could have long‐term developmental and reproductive toxicity (DART) effects. Therefore, the use prevalence and abuse liability of electronic nicotine delivery systems (ENDS) among adolescents and youth, and during pregnancy, raises concerns about possible exposure to endocrine disruptors. In addition, endocrine disruptors have adverse effects on wildlife and environmental health. While many studies focus on carcinogenicity and mutagenicity of tobacco products, research efforts screening chemicals in tobacco products for endocrine disruption potential are few. In this study, we curated 5179 chemicals in tobacco and tobacco smoke, 2803 flavor chemicals, and 156 e‐liquid chemicals from literature or openly available databases. We screened the chemicals for endocrine bioactivity using new approach methodologies (NAMs) developed through US Environmental Protection Agency's Endocrine Disruptor Screening Program. The specific NAMs, estrogenic and androgenic pathway models, identified 137 tobacco chemicals, 34 flavor chemicals, and three e‐liquid chemicals (Veratraldehyde, (2E)‐3‐Phenylprop‐2‐enal, and 2′‐Acetonaphthone) as “active,” indicating potential endocrine bioactivity. Further, among the tobacco chemicals with endocrine bioactivity potential, 48 were environmentally persistent, 29 bioaccumulative, and 19 both persistent and bioaccumulative. Our findings document many chemicals in tobacco products with potential endocrine bioactivity, which raises concerns for both human and environmental health. These results also underscore the importance of DART potential of tobacco products and flavors. Overall, our study characterizes the endocrine bioactivity potential of tobacco and flavor chemicals and provides a list of chemicals to consider in future ecological and health risk assessments.
Cultivating the Genius Within: A Conceptual Framework for Black Feminist Text Selection
Authors: Griffin Autumn A. , Ferguson Latrice , Crawford Angela , Thomas Ebony Elizabeth 
Published: January 2025

AbstractTeachers' choices as they select texts have long been explored and considered by researchers. However, within such scholarship, there is limited research about how teachers, particularly Black women teachers, navigate the gauntlet of whitewashed standards, hegemonic curriculs, and dehumanizing school spaces to select texts that affirm students and support their learning. This paper asks what choices one experienced Black woman teacher makes in selecting texts in response to her students' identities and her own learning experiences. Drawing on Black Feminist scholarship, this article focuses on how memory, self‐reflection, personal experiences, and a desire for equity are all a part of selecting culturally relevant texts. Moreover, we illustrate that Black women teachers see text selection as a part of larger care practices and community building within their classrooms.
Better Together: Integrating Content‐Area Curriculum in the Primary Literacy Classroom
Authors: Ryan Allison , Lipp Jamie R. 
Published: January 2025

AbstractIntegrating content‐area and literacy instruction in primary‐grade classrooms creates authentic and engaging opportunities for students to build background knowledge and literacy skills. Furthermore, when students engage in meaningful dialogue about content‐area topics they can discuss complex ideas and use content‐specific vocabulary. These authentic conversations, combined with hands‐on experiences and children's literature, build a strong foundation for students to become successful readers and writers. Existing and current literature highlights knowledge building and its impacts on literacy achievement, often supported through integrated instruction. The subsequent experiences in a first‐grade classroom confirm this impact, yielding promising results. However, there continues to be a need for more research and professional development opportunities to ensure equitable, accessible, and effective implementation for all learners.
Mandatory Initial Mediation Session: Evaluating the Effects of Compulsion in Dispute Resolution—The Case of North Macedonia
Authors: Kamilovska Tatjana Zoroska , Rakočević Milka 
Published: January 2025

Abstract
Since the adoption of the first Law on Mediation in 2006 until today, various regulatory measures have been undertaken for the promotion and stimulation of mediation in North Macedonia. The mediation model has undergone multiple changes given that the practical experience has consistently indicated that the results of its application are minor. Amendments to the Civil Procedure Act from 2015 introduced a mandatory initial mediation session in commercial disputes up to a certain value as a promising solution in the context of its further promotion. The reasons for this legislative solution were quite poorly explained. The absence of specific indicators for the need of a mandatory initial mediation session in commercial disputes mobilized resistance among many business entities but also among the members of the legal profession. A small number of comparative experiences from EU countries, as well as the initial organizational problems with its implementation in our country, have raised doubts about the perspective of this solution. It seems that several years after the introduction of a certain extent of compulsion in the system of dispute resolution regarding particular commercial disputes is quite a solid time to assess the success of this solution so far, but also to estimate whether such a solution has a long-term potential of reviving mediation in our country and creating a culture of using mediation on a purely voluntary basis.
