Published: February 2025

AbstractHoneycomb composites show excellent properties with higher specific stiffness and strength compared with traditional composites. This work designed and manufactured a novel three‐dimensional honeycomb composite with an integrated honeycomb core structure through three‐dimensional woven fabricating technology. The influences of boundary effects, hole size and sample width of honeycomb core composites were respectively investigated through experimental and numerical methods. The results show that the rise of free wall number at the edges caused compressive properties to decrease in the weft direction but increase in warp and out of plane directions. The strength of multi free wall samples (2 main bodies) only reaching 93.6% of the few free wall samples (3 main bodies). The mechanisms of hole size affecting the compressive properties include many complicated factors such as structural scale‐law and curing defects. Finally, the decrease of compressive strength along the weft direction with the rise of width was also due to the earlier buckling failure of the honeycomb wall. The investigation of this work benefits to the design and application of the proposed honeycomb composites in many special fields.Highlights

AbstractThis paper presents the development of a high‐performance silk‐based polymer composite with enhanced thermal conductivity and electromagnetic interference (EMI) shielding capabilities. This composite achieved significantly improved thermal and electrical properties by incorporating 3‐(aminopropyl)triethoxysilane (APTES)‐functionalized reduced graphene oxide (rGO) and silver nanoparticles (AgNPs) into a silk nanofiber (SNF) matrix. The APTES surface treatment enhanced the chemical bonding between the filler–filler and filler–matrix interfaces, resulting in enhanced compatibility and dispersion, as well as the formation of effective conductive networks. Furthermore, the incorporation of AgNPs facilitated conductive bridging between the rGO sheets and the SNF matrix, thereby enhancing the continuity of thermal and electrical pathways. By employing an aerogel intermediate layer in conjunction with hot‐pressing techniques, a dense and compact structure with continuous conductive pathways was created. Owing to this synergistic approach, the SNF/f‐rGO@Ag composite achieved a high through‐plane thermal conductivity of 4.23 W/m·K and an EMI shielding effectiveness (EMI SE) of 59.1 dB. These properties render the composite well‐suited for applications in advanced electronic devices that require efficient thermal management and robust EMI shielding.Highlights
APTES surface functionalization improves filler dispersion and compatibility.
f‐Ag acts as a bridge between f‐rGO themselves and the SNF matrix.
Aerogel intermediate contributes to the formation of continuous conduction pathways
SNF/f‐rGO@Ag composite achieved 4.23 W/m·K through‐plane thermal conductivity.
EMI shielding effectiveness of SNF/f‐rGO@Ag reached 59.1 dB, outperforming benchmarks.

Published: February 2025

ABSTRACTInterpersonal teacher behavior can be described with the Interpersonal Circumplex on the dimensions of communion (warmth, sensitivity) and agency (initiative, control). In an observational study, we investigated whether a teacher's interpersonal behavior in dyadic interactions with a student is complementary to the student's communion and scholastic competence: Does the teacher act communal to the extent that the student behaves communal, and does the teacher act more agentic the less competent the student is? In 39 primary and secondary schools, we conducted direct classroom observations for two teacher‐student dyads each (78 dyads). Using Structural Summary Method, we found as expected that teacher communion was positively associated with student communion, to the detriment of students who have not yet learned to behave in a communal manner. Further, results showed a negative association between teacher agency and student competence, suggesting that teachers engaged in adaptive teaching. Results further showed that weak teacher communion was related to low student competence. We discuss the implications for teacher education and training, namely that teachers should be trained to prevent falling into patterns of dysfunctional, non‐communal behavior when confronted with a particular set of student characteristics and behaviors.

Published: February 2025

ABSTRACTJob burnout is becoming a major threat to teachers' work. Previous studies revealed that teachers' professional identity and job burnout are negatively related. This study explored the mediating effects of career satisfaction and work engagement in the relationship between teachers' professional identity and job burnout. Investigation materials included the Chinese version of the Teachers' Professional Identity Scale, Career Satisfaction Scale, Utrecht Work Engagement Scale, and Professional Quality of Life Scale. The cross‐sectional design was conducted in this study with 3147 teachers from kindergarten, primary, and secondary schools in Zhejiang Province, China. The PROCESS macro plug‐in SPSS21.0 was used for mediating effect analysis. These results indicated that teachers' professional identity, career satisfaction, and work engagement have significant, positive correlations with each other and significant negative correlations with job burnout. Meanwhile, results showed that career satisfaction and work engagement played parallel and sequentially mediating roles in the relationship between teachers' professional identity and burnout. These findings indicate that a high level of professional identity plays an important role in strengthening career satisfaction and increasing work engagement, which may effectively help teachers reduce job burnout.

AbstractBACKGROUNDWheat powdery mildew is an airborne multi‐cycle disease caused by Blumeria graminis f. sp. tritici. This disease can cause severe yield reduction or total crop loss. Fluopyram is a succinate dehydrogenase inhibitor (SDHI) used for the prevention and control of gray mold, powdery mildew, and downy mildew in fruits and vegetables.RESULTSWe used fluopyram to treat wheat seeds and demonstrated excellent control of powdery mildew. Fluopyram treatment did not affect wheat seed germination. After seed treatment, the residual amounts of fluopyram in harvested wheat grains and in soil were lower than the maximum residue limit (MRL, 0.07 mg kg−1). We explored the mechanism of action of fluopyram on wheat powdery mildew using eukaryotic reference transcriptome analysis. The differentially expressed genes (DEGs) in wheat plants treated with fluopyram were mostly enriched in the photosynthesis pathway. SPAD (soil–plant analysis development) value measurements showed a significant increase in chlorophyll content after treatment. The enzyme activity of chitinase and the relative expression levels of related genes (Cht3 and Cht4) were significantly up‐regulated, indicating that the defense response of wheat was activated.CONCLUSIONFluopyram seed treatment is expected to be developed for the control of wheat powdery mildew. The research in this study will provide important theoretical basis for controlling wheat powdery mildew caused by Blumeria graminis f. sp. tritici in the field. © 2025 Society of Chemical Industry.

Published: February 2025

ABSTRACTIn recent years, immunotherapy has become a novel antitumor strategy in addition to traditional surgery, radiotherapy, and chemotherapy and has exhibited promising results in clinical applications. Despite significant breakthroughs in immunotherapy, such as immune checkpoint blockade and CAR‐T cell therapy, it remains necessary to develop more efficacious, safer, and cheaper immunotherapeutic drugs due to factors including small reaction populations, acquired resistance, adverse side effects, and high costs. Natural killer (NK) cells are preeminent cytotoxic lymphocytes of the innate immune system that act as the first line of defense against tumors and synergistically enhance the adaptive immune response of T lymphocytes. Therefore, boosting the antitumor function of NK cells is an important direction in the development of immunotherapy. For decades, various immunotherapies such as adoptive cell therapy, antibody drugs, cytokines supplement, and chemical immunomodulators have been developing rapidly to improve the function of NK cells. Compared to biological immunotherapy, immunomodulators derived from natural products have outstanding advantages of low immunogenicity, multi‐targeting, and cost‐effectiveness. Currently, increasing attention is being focused on discovering NK cell‐stimulating agents from natural products, such as polysaccharides, alkaloids, terpenoids, saponins, phenolics, and quinones. This review aims to categorize and summarize the comprehensive research progress on these natural products, discuss their potential molecular mechanisms in regulating NK cells, and explore their clinical applications as standalone treatments or in combination with conventional chemotherapy regimens.

AbstractArtificially aligned or positioned functional materials are essential building blocks for modern devices and nanoelectronics. Since the emergence of 2D materials, the vertical stacking/integration of exotic materials has garnered increasing attention. However, controlling homostructures, e.g. identical materials conjoined with varying crystalline orientations, magnetism, or strain states, along the lateral direction remains challenging. Leveraging on the freestanding thin film growth techniques, the concept of twisted lateral homostructures has been introduced, enabling precise control over the lateral alignment of crystalline directions. Here, using La0.7Sr0.3MnO3, a classic strongly correlated material, the precise manipulation of epitaxial strain alongside the homojunction is demonstrated. This leads to a precisely controllable lateral homostructure composed of polymorphic ferromagnetic and antiferromagnetic La0.7Sr0.3MnO3 regions. It is further identified that the interactions between the ferromagnetic and antiferromagnetic regions of La0.7Sr0.3MnO3 lead to unconventional ultrafast spin dynamics and magnetotransport behavior. The results provide a promising platform for developing novel emergent phenomena and functionalities in the twisted lateral homostructures.

AbstractThe accelerated demand for electrochemical energy storage urges the need for new, sustainable, and lightweight materials able to store high energy densities rapidly and efficiently. Development of these functional materials requires specialized techniques that can provide a close insight into the electrochemical properties at the nanoscale. For this reason, the electrochemical scanning microwave microscopy (EC‐SMM) enabling local measurement of electrochemical properties with nanometer spatial resolution and sensitivity down to atto‐Ampere electrochemical currents is introduced. Its power is demonstrated by studying NiCo‐layered double hydroxide flakes, revealing active site locations and providing atomistic insights into the catalytic process. EC‐SMM's spatial resolution of 16 ± 1 nm allows detailed analysis of edge effects in this 2D material, including localized electrochemical impedance spectroscopy and cyclic voltammetry. Coupled with advanced numerical modeling of diffusion and migration dynamics at the material interface, the findings elucidate the previously hypothesized processes responsible for localized enhancements in electrochemical activity, while pinpointing essential parameters for tuning the thermodynamics of ion intercalation and optimizing surface adsorption.

ABSTRACTOne of the main downsides of enzyme immobilization, aside from a noticeable reduction of enzyme activity, is the difficulty in detecting and tracking migration and biodistribution of the nanocarrier toward the target site. The intrinsic fluorescence property of carbon nanospheres (CNSs) makes them useful for tracking and localization. This research aims to prepare a set of nanosystems based on pristine CVD‐produced CNSs (CNS0%), functionalized CNSs (CNS3%), and size‐reduced CNSs (s‐CNS) subjected to a procedure for α‐amylase enzyme immobilization, to later evaluate their biological activity. These structures have been characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, Raman and fluorescence spectroscopy, and thermogravimetric analysis. Results showed that surface functionalization and nanoplatform size play an important role in boosting enzymatic activity. Moreover, all the samples demonstrated high thermal stability and fluorescence even after attaching α‐amylase to their surface which can provide great functionality for a variety of applications.

ABSTRACTWater quality parameters (WQPs) are an important aspect of a significant role in addressing the issue of aquatic animals and human health hazards. There is increasing concern that some microplastics (MPs) are being disadvantaged and directly affected by aquatic organisms and potential health risks. Research has consistently shown that physiochemical parameters are lacking in the Surma River. This study examines the seasonal fluctuations in water toxicology and the effects of MPs on freshwater ecosystems in the Surma River. Data were gathered from three locations during the monsoon, winter, and summer seasons of 2023–2024 at 4‐month intervals. The analysis revealed concerning WQPs, water quality index (WQI), and pollution index values, indicating serious threats to aquatic life. FTIR microscopy detected MPs, with fibers being the most common (55%), followed by fragments (28%), films (10%), and foam (6%). The highest pH recorded was 8.44 at Station 1 during the summer, while the lowest pH fell to 7.02 in winter. Station 3 exhibited the lowest WQPs, reaching a minimum of 0.15 in winter. The monsoon season showed the most pronounced changes, with heightened pollution levels due to flooding, which diminished habitat suitability. The presence of MPs adds complexity to water quality by introducing harmful pollutants that accumulate in fish, threatening both aquatic ecosystems and human health. These results highlight the critical need for robust water quality management strategies and further research into the ecological and health effects of MPs in freshwater environments. This study enhances our understanding of the seasonal variations in water toxicity and the contribution of MPs to water pollution.

AbstractLeptotrombidium rupestre, a chigger species, is a potential vector of scrub typhus. Based on field surveys in southwest China between 2001 and 2022, this paper retrospectively reports the distribution and host selection of L. rupestre in the region for the first time. A total of 4675 L. rupestre were identified from 28 species of rodents and other sympatric small mammal hosts in 23 out of 114 survey sites, and it was mainly distributed in higher latitudes (31–33° N) and altitudes (3000–3500 m), especially in western Sichuan, an important focus of scrub typhus. Among four orders of hosts, 96.15% (4495/4675) of L. rupestre were found on the order Rodentia. At species level of hosts, 40.49% of L. rupestre (Cr = 40.49%, 1893/4675) came from the vole Alexandromys oeconomus in Cricetida of Rodentia, with high prevalence (PM = 91.67%), mean abundance (MA = 157.75 chiggers/per examined vole) and mean intensity (MI = 172.09 chiggers/per infested vole), indicating an obvious host‐preference. L. rupestre was of aggregated distribution among different individuals of the hosts. The occurrence of L. rupestre in western Sichuan may increase the potential risk of the focus persistence of scrub typhus in the region. The present study enriches scientific information on this potential vector species and will contribute to the surveillance and control of scrub typhus in the future.

Different growth response of mountain rangeland habitats to inter-annual weather fluctuations
Authors: Oriani Fabio , Aasen Helge , Schneider Manuel K. 
Published: February 2025

Abstract
Monitoring mountain rangelands is crucial for ensuring the sustainability of pastoral land use. In this study, we employ satellite image analysis to investigate how the seasonal growth patterns in the mountain rangeland ecosystem respond to inter-annual variations in weather conditions along the elevation profile. Our analysis covers nine key habitats in mountain rangelands surrounding the Swiss National Park, southeastern Swiss Alps from 2000 to 2800 m of elevation. Using the Normalized Difference Vegetation Index (NDVI) to track the growth pattern from 2016 to 2023 reveals that inter-annual weather fluctuations affect all habitats, leading to variations of 15–20% in the growth curve, with more significant impacts observed in the first half of the growing season. When comparing growth among habitats, wet and mesic pastures tend to exhibit greater growth compared to dry habitats within the elevation range of 2000–2400 m above sea level, while all habitats show a similar growth above 2400 m. Additionally, the presented statistical analysis at the landscape scale supports the existence of growth dynamics previously observed at the plot scale: that snow persistence influences the beginning of growth in pastures, but this effect is partially compensated by rapid growth following late snow melt. Conversely, in the second half of the season, growth is controlled by the onset of snow in autumn. These results demonstrate the potential of the joint application of earth observation and spatial statistics, not only to monitor the regional response to climate trends and variability, but also to differentiate inter-annual and inter-habitat responses of growth dynamics.
