Thermal buckling of composite laminates with elastic boundaries
Authors: Changfu Hu , Weicheng Gao 
Published: January 2025

AbstractThe investigation of thermal buckling in composite laminates holds significant theoretical and practical implications. For the commonly encountered rectangular thin plate structures in engineering, this study aims to explore their buckling characteristics under thermal loads in arbitrary elastic boundary conditions. To achieve this, a method based on the principle of minimum potential energy for calculating the buckling load during elastic instability is presented. Initially, transverse constraint springs and rotational constraint springs are set at the four boundaries of the plate structure model, with the stiffness values of these two types of elastic springs designated to simulate arbitrary elastic boundary conditions. The improved Fourier series is employed to address potential discontinuities in the boundary derivatives of displacement functions that may arise with the classical Fourier series form. Subsequently, the potential energy expression for the rectangular plate system is established. By combining this with the principle of minimum potential energy, a system of linear equations is derived through partial differentiation of the unknown Fourier coefficients. Finally, the critical buckling load and other parameters of the rectangular plate are obtained, with reasonable values for the spring stiffness under different boundary conditions provided. The critical buckling temperatures derived from the proposed method are compared with those obtained via finite element analysis. The results indicate that the buckling loads obtained using this method align closely with those from finite element analysis, affirming the validity and convergence of the research methodology.Highlights

Published: January 2025

AbstractThe purpose of this study is to develop green composites prepared from bio‐derived polybenzoxazine (PBz) and glass fiber (GF). The effects of GF contents (22.7, 30.6, 39.8, 50.7, and 63.8 vol%) on mechanical, thermal and surface properties, self‐healing behavior and UV‐protection property were evaluated. Flexural properties, thermal stability and flame resistant of the composite samples was substantially improved by the presence of GFs, while the thermal expansion and water contact angle was progressively reduced with the GF content. The self‐healing efficiency assessed through self‐healing percentage under flexure content confirm that the composite samples showed good self‐healing performance with the self‐healing percentage within 59.5–83.8. In addition, reinforcing GF also exhibits an enhanced ultraviolet shielding efficiency of the composite samples closed to 100%. Based on the composite's mechanical and thermal properties, self‐healing efficiency, flame resistant and UV‐protection property, its potential usage is suggested in advanced application such as structural materials with associated requirements of significant self‐healing, self‐extinguishing and ultraviolet‐shielding property.Highlights
Green GF/bio‐derived polybenzoxazine composites was successfully developed.

Published: January 2025

AbstractThe study investigates the effects of graphene oxide/zinc oxide (GO‐ZnO) nanohybrids, combined with Mentha longifolia essential oil, on the mechanical, UV resistance, antibacterial, and rheological properties of polylactic acid (PLA). GO‐ZnO nanohybrids were prepared at ZnO‐to‐GO ratios of 1:1 and 2:1 and incorporated into PLA at various concentrations. The addition of GO‐ZnO significantly enhanced the tensile strength and modulus of PLA composites due to strong interactions between PLA and the functionalized nanohybrids. Hydrolytic degradation tests revealed accelerated PLA degradation with GO‐ZnO, attributed to the catalytic effects of ZnO. Rheological analysis showed reduced elasticity with higher nanohybrid content, attributed to thermal degradation. UV absorption tests demonstrated improved UV protection with GO‐ZnO and essential oil. Antibacterial tests indicated higher inhibition percentages against E. coli and Listeria, highlighting a synergistic antibacterial effect of the hybrid system. These findings suggest PLA/GO‐ZnO/oil composites are promising candidates for antibacterial packaging applications.Highlights

Published: January 2025

AbstractA series of dithioazaspiroacrylamide monomers containing sulfur atoms in the cyclic structure and having high refractive indices have been synthesized. Transparent polymer films were obtained from these monomers. The refractive indices of monomers and polymers obtained from them were measured (  = 1.52–1.67) and their Abbe numbers were also measured (VD = 26–55). The glass transition temperatures of polymers were measured Tg = 45–155°C. Polymers consisting of spirocyclic unbranched units showed the highest refractive indices and high transparency, which seems promising for use in photolithography, holography, elements of polymer, and waveguide optics.Highlights

ABSTRACTEncapsulation is a critical topic to ensure the successful implementation of perovskite photovoltaics. Recently, vacuum lamination has been shown as a promising approach that combines compatibility with current industrial processes in conventional photovoltaic (PV) manufacturing and suitability to achieve good results with perovskites. Here, we explore some of the attractive encapsulation materials in terms of their ability to prevent moisture ingress, withstand elevated temperatures, and have suitable mechanical properties to avoid thermomechanical issues. We utilized the previously suggested concept of the “perovskite test,” an optical test with simple sample fabrication, for evaluating encapsulation quality and validated the findings with the full solar cell stack. Unsurprisingly, encapsulants without an edge sealant showed insufficient protection from moisture. Ionomer in combination with butyl edge seal showed the best barrier properties; however, this stack led to rapid delamination of the cell layers in thermal cycling tests. Configuration with only edge sealant does not have such an issue in principle (no mechanical stress applied), but an absence of the polymer in the stack is unfavorable in terms of optical design and sometimes showed perovskite degradation that we assign to trapped moisture in the butyl itself. Polyolefin with butyl edge sealant is not free of degradation but showed the most promising compromise by passing the damp heat test and showing fewer issues in the thermal cycling experiments. In general, our material study and optimization presented in this manuscript show that a holistic approach is needed when choosing an optimal encapsulation scheme for perovskite devices.

Published: January 2025

AbstractObjectiveTo review and synthesize existing evidence on the effect of mirror therapy (MT) on motor and functional recovery and the effect of unimanual and bimanual MT in individuals with subacute stroke.MethodologyPubMed, Physiotherapy Evidence Database, Cochrane, and Airiti Library were searched for relevant studies. Randomized and pilot randomized controlled trials comparing MT with sham MT or conventional therapy were included. Three researchers independently reviewed eligible studies for study design, participants' characteristics, intervention, and outcome measures and assessed study quality. The Physiotherapy Evidence Database scale was used to evaluate the methodological quality of included studies, and the Cochrane Risk of Bias Tool was used to assess the risk of bias.SynthesisFifteen studies with 546 participants were included. An overall effect of MT was found for motor impairment (effect size [95% confidence interval]: 0.473 [0.274–0.673], p < .001), motor function (0.266 [0.059−0.474], p = .012), and activities of daily living (ADL) (0.461 [0.25–0.671], p < .001), compared with controls. There was a significant difference in motor impairment (0.39 [0.134–0.647], p = .003), motor function (0.298 [0.003–0.593], p = .048), and ADL (0.461 [0.157–0.766], p = .003) in favor of bimanual MT compared with controls. No significant effect was found for unimanual MT.ConclusionMT, specifically bimanual MT, is an effective intervention for improving motor recovery, motor function, and ADL in individuals with subacute stroke, whereas unimanual MT does not show significant benefits in these areas.
Quantifying Permafrost Degradation Processes: Real‐Time Analysis Using Environment‐Based Particle Image Velocimetry and Weather Data

Published: January 2025

ABSTRACTWe present an innovative approach to understanding permafrost degradation processes through the application of new environment‐based particle image velocimetry (E‐PIV) to time‐lapse imagery and correlation with synchronous temperature and rainfall measurements. Our new approach to extracting quantitative vector movement from dynamic environmental conditions that can change both the position and the color balance of each image has optimized the trade‐off between noise reduction and preserving the authenticity of movement data. Despite the dynamic polar environments and continuous landscape movements, the E‐PIV provides the first quantitative real‐time associations between environmental drivers and the responses of permafrost degradation mechanism. We analyze four event‐based datasets from an island southwest of Tuktoyaktuk, named locally as Imnaqpaaluk or Peninsula Point near Tuktoyaktuk, NWT, Canada, spanning a 5‐year period from 2017 to 2022. The 2017 dataset focuses on the interaction during a hot dry summer between slope movement and temperature changes, laying the foundation for subsequent analyses. In 2018, two datasets significantly expand our understanding of typical failure mechanisms in permafrost slopes: one investigates the relationship between slope movement and rainfall, while the other captures an overhang collapse, providing a rare quantitative observation of an acute landscape change event. The 2022 dataset revisits the combination of potential rain and air temperature‐related forcing to explore the environment–slope response relationship around an ice wedge, a common feature of ice‐rich permafrost coasts. These analyses reveal both a direct but muted association with air temperatures and a detectable delayed slope response to the occurrence of rainfall, potentially reflective of the time taken for the warm rainwater to infiltrate through the active layer and affect the frozen ground. Whilst these findings also indicate that other factors are likely to influence permafrost degradation processes, the associations have significant implications given the projections for a warmer, wetter Arctic. The ability to directly measure permafrost slope responses offers exciting new potential to quantitatively assess the sensitivity of different processes of degradation for the first time, improving the vulnerability components of hazard risk assessments, guiding mitigation efforts, and better constraining future projections of erosion rates and the mobilization of carbon‐rich material.
A bibliometric analysis of the SCOPUS‐indexed research on written peer feedback
Authors: Saeli Hooman , Rahmati Payam , Koltovskaia Svetlana 
Published: January 2025

AbstractThe present study aimed to explore the major patterns in the available scholarship on peer feedback in the writing classroom. In doing so, a bibliometric approach was utilised, where a nearly exhaustive search was conducted on the SCOPUS‐indexed documents on peer feedback. After compiling a database, the scholarship on peer feedback was divided into three timelines: 2000–2010, 2011–2020 and 2021–2024. The subsequent analysis highlighted the salient research trends in the number of documents published on the topic of peer feedback, the most prolific authors and venues (e.g., academic journals), the most influential institutions and countries, and the most highly researched topics. The results, for example, showed a substantial increase in the number of documents published on peer feedback. The higher number of documents on peer feedback in recent years is probably caused by the increasing attention paid to such notions as learner autonomy, learner engagement with feedback, and more learner‐centred methods of providing feedback.
Context and implicationsRationale for this study: This study is the first bibliometric analysis of peer feedback research, providing a comprehensive overview of trends and developments in peer feedback research over the past three decades.Why the new findings matter: Our findings provide quantitative insights into research trends on peer feedback in second language writing studies.Implications for researchers and practitioners: Our research findings indicate a steady growth in peer feedback studies over the past three decades. We believe future research will likely focus on digital and multimodal peer feedback, driven by the ubiquity of digital platforms. Researchers should explore how these platforms can enhance peer feedback practices and improve learner engagement. Additionally, we recommend that researchers conduct empirical studies within multimodal spaces, focusing on learners as both providers and receivers of feedback. These studies can offer practical insights that can be directly applied by teachers to improve feedback practices in the classroom.
Autoethnography in medical education: Ethical and legal considerations
Authors: Seah K. T. Matthew 
Published: January 2025

AbstractFor medical educators, autoethnography as a research methodology provides a means of active engagement in reflective practice, ranging from teaching and educational innovation to interactions with patients and colleagues. In this way, they may benefit from the systematic reflexivity required, improve their interactions with the people around them, as well as demonstrate ongoing personal development and improve their skillset as an educator. On a wider level, autoethnography has the potential to study a culture or a phenomenon as it is directly and personally experienced by the author, thereby providing unique insight into medical education theories and/or the patient‐physician relationship. As autoethnography often examines sensitive issues, hidden aspects of our lives or untold stories, it is clear that autoethnography poses several ethical and moral challenges which must be considered when the relevant research is planned. In this essay, I will discuss some of the ethical considerations of autoethnography which are relevant in the medical education context, and highlight potential legal considerations of these published personal reflections. To do this, I will discuss issues of validity with autoethnography, ownership of the stories, the tension between authenticity and anonymity, ethics of representation of study participants and relevant legal issues which may impact the use of autoethnography in the healthcare setting.
Context and implicationsRationale for this study: Autoethnography as a research methodology provides a means of active engagement in reflective practice, and should lend itself to research in medical education and healthcare research.Why the new findings matter: As this is a relatively new methodology in the context of medical education, there are several challenges to adoption and researchers should be aware of some of the ethical and legal considerations.Practical implications: This article aims to highlight some of the issues for researchers who are considering autoethnography as a research methodology in the healthcare setting.
Molecular and cellular regulators of embryo implantation and their application in improving the implantation potential of IVF‐derived blastocysts
Authors: Liu Chunyan , Fukui Emiko , Matsumoto Hiromichi 
Published: January 2025

AbstractBackgroundIn vitro fertilization (IVF) and embryo transfer (ET) are widely used in reproductive biology. Despite the transfer of high‐quality blastocysts, the implantation rate of IVF‐derived blastocysts remains low after ET.MethodsThis article provides a comprehensive review of current research on embryo implantation regulators and their application to improve the implantation potential of IVF‐derived blastocysts.Main FindingsThe in vivo mouse model revealed selective proteolysis immediately after expression in activated blastocysts, that is, degradation of ERα expression in activated blastocysts regulated by the ubiquitin‐proteasome pathway, followed by completion of blastocyst implantation. Treatment of blastocysts to induce appropriate protein expression during in vitro culture prior to ET is a useful approach for improving implantation rates. This approach showed that combined treatment with PRL, EGF, and 4‐OH‐E2 (PEC) improved the blastocyst implantation rates. Furthermore, arginine and leucine drive reactive oxygen species (ROS)‐mediated integrin α5β1 expression and promote blastocyst implantation.ConclusionFindings based on analysis of molecular and cellular regulators are useful for improving the implantation potential of IVF‐derived blastocysts. These approaches may help to elucidate the mechanisms underlying the completion of the blastocyst implantation, although further investigation is required to improve the success of implantation and pregnancy.
Observer‐Based Containment Control for Linear Parameter‐Varying Multi‐Agent Systems
Authors: Liu Yanjie , Li Zhi 
Published: January 2025

ABSTRACTThis paper investigates the observer‐based containment control problem of linear parameter‐varying (LPV) multi‐agent systems (MASs) with zero or nonzero leaders' inputs under both fixed and switching directed communication topologies. The corresponding distributed observer‐based containment control protocols are proposed for the system. The containment control problem of open‐loop LPV MASs is transformed into the stability problem of the closed‐loop systems. The sufficient conditions for the stability of the closed‐loop system are derived in terms of linear matrix inequalities (LMIs) to realize the containment control of LPV MASs. Finally, simulation examples are presented to demonstrate the effectiveness of the proposed protocols.
