Published: September 2024

AbstractAqueous all‐organic batteries (AAOBs) have emerged as a hot topic but their development was plagued by limited choices of anode materials, generally facing an intractable trade‐off between low potential and high stability. Here, we propose a novel π‐electron bridge engineering strategy to explore a class of 2D dioxin‐bridged redox covalent organic polymer (RCOP) as trade‐off‐breaking anodes for high‐voltage AAOBs. By establishing a tunable RCOP platform, we perform theoretical study to scrutinize how bridge units between active sites affect the electrode potential and redox activity for the first time. We discover that compared to common pyrazine bridge, the weakened conjugation and strong electron donor character of the proposed dioxin bridge can induce elevated LUMO level and enriched π‐electron populations in active sites, heralding a low electrode potential and enhanced redox activity. Besides, the nonaromaticity‐induced molecular flexibility of dioxin bridge mitigates intermolecular stacking for sufficient active sites exposure. To experimentally corroborate this, a new dioxin‐bridged 2D RCOP (D‐HATN) and its pyrazine‐bridged analogue (P‐HATN) are synthesized for proof‐of‐concept demonstration. D‐HATN displays excellent compatibility with Na+/Zn2+/NH4+/H3O+ and obviously lower redox potentials in various dilute electrolytes compared to P‐HATN and most reported organic anodes, while featuring rapid Grotthuss‐type proton conduction and unprecedented durability in acid – 91.8 % capacity retention after 20000 cycles. Thus, the D‐HATN‐involved all‐organic proton battery delivers an average output voltage of 0.75 V, which can be further elevated to 1.63 V with alkaline‐acidic hybrid electrolyte design, affording markedly‐increased specific energy.

Published: September 2024

AbstractSulfur dots (SDs) have emerged as promising photoluminescence (PL) materials owing to their intrinsic merits such as abundant electronic effects, outstanding biocompatibility and available photocatalytic activity. Typically based on quantum confinement effects, SDs are reported usually confined emission in blue‐to‐green region. However, it is challenging to achieve their broad emission tunability in the visible region, restricted by inherent band gap of bulk sulfur (ca. 2.79 eV). Herein, we present white‐light‐emitting SDs achieved by surface charge engineering that hybridizes the surface of SDs with oleylamine. The resulting SDs exhibit broadband emissions (full width at half maximum of 187 nm) with PL quantum yields of up to 12.1 % and Commission International de I'Eclairage color coordinates of (0.27, 0.32). Detailed experimental and theoretical analysis reveal that the strong orbital coupling between oleylamine and sulfur on the hybrid surfaces of the SDs causes electron delocalization, leading to the generation of low‐energy charge transfer (CT) states. These CT states are highly sensitive to sulfur‐oleylamine hybrid structures, which complicate the transition dynamics and promote multi‐energy emissions, accounting for efficient white‐light emission. The demonstration of white‐light SDs based on surface charge engineering is an important step towards the development of sulfur‐based PL materials.
Two‐Dimensional Supramolecular Polymorphism in Cyanine H‐ and J‐Aggregates

Published: September 2024

AbstractWe designed a new cyanine dye 1, with two pedant rod‐like groups, capable of forming two distinct two‐dimensional (2D) supramolecular polymorphs in methylcyclohexane; an H‐type aggregate (Agg‐H2) and a J‐type aggregate (Agg‐J). Importantly, these two polymorphs were not accessed through polymerization events, and instead through the thermal transformation of a third particle‐like polymorph (Agg‐H1) formed by the anti‐cooperative assembly of 1. While Agg‐H2 is generated upon cooling the solution of Agg‐H1 by a thermoreversible polymorph transition, the Agg‐J was obtained through a hidden pathway by combining sonication and cooling to the Agg‐H1 solution. This is the first report on the obtention of H‐ and J‐type cyanine polymorphs that in turn could be isolated in solid‐state to render two new 2D photoactive materials. This paper unveils new strategies for designing 2D supramolecular polymers using calamitic residues, but also undercovers relevant aspects of pathway complexity and polymorph transitions that might be crucial for developing novel photonic systems

AbstractThis study aimed to evaluate the potential of ethanolic extract of propolis on the secondary lesions of the liver, renal, and pancreatic that were derived by primary colorectal cancer, and comparison of the ethanolic extract of propolis with the vitamin E. The groups included the control, ethanolic extract of propolis, vitamin E, dimethylhydrazine, dimethylhydrazine + ethanolic extract of propolis, and dimethylhydrazine + vitamin E. After 13 weeks of treatment, the blood and tissue samples were taken from all the rats, and alanine transaminase, aspartate transaminase, alkaline phosphatase, uric acid, creatinine, blood urea nitrogen, insulin, amylase, and lipase indices along with the tissue pathological examination of the kidney, liver, and pancreas were evaluated. Ethanolic extract of propolis effectively alleviated the colorectal cancer‐induced secondary lesions in the liver by significantly lowering the alanine transaminase significantly. Ethanolic extract of propolis significantly decreased uric acid in rats; and also significantly elevated the pancreatic insulin. In addition, inflammation and cell necrosis indices in all these tissues were significantly reduced when ethanolic extract of propolis was consumed compared to the dimethylhydrazine group. It seemed ethanolic extract of propolis showed high antioxidant, anticancer, and anti‐inflammatory potentials, and can be used practically to reduce the side lesions of colorectal cancer.

Published: September 2024

AbstractNanotechnology, which involves manipulating matter at the atomic and molecular scales to produce structures and devices ranging from 1 to 100 nm, is increasingly being applied in agriculture. Nanoscale materials possess distinct optical, electrochemical, and mechanical properties that enable the smart, targeted delivery of pesticides, fertilizers, and genetic materials to plants, as well as rapid sensing and on‐site monitoring of plant health, soil fertility, and water quality in a digital format. This review explores the application of nanotechnology in agriculture, examining the challenges and benefits related to all aspects of crop production, with a particular focus on regulatory issues. Key findings indicate that nanotechnology can improve crop production and reduce the environmental footprint of agriculture through precise input management. However, several critical issues need to be addressed, including the limited knowledge of the long‐term environmental impacts associated with agricultural nanotechnology and the ambiguity of current regulations. This underscores the need for further research to elucidate its impact on soil, water, and environmental and human health, to inform evidence‐based regulations. © 2024 The Author(s).

Published: September 2024

AbstractWhile existing literature has extensively examined the correlation between social media usage and body dysmorphic disorder (BDD) in adolescents, research on this relationship among adults remains limited. Thus, this study sought to explore the association between social media engagement and BDD in adults. A sample of 222 participants completed a questionnaire comprising various scales to assess the influence of social media usage and time spent on these platforms on body dissatisfaction. The results revealed a positive correlation between social media usage and symptoms of body dissatisfaction, as well as low self‐esteem. Notably, increased time spent on social media emerged as a significant predictor of body dissatisfaction. Moreover, a significant link was observed between self‐esteem and Appearance‐Related Consciousness concerning image uploads on social media platforms. Image‐centric platforms like Snapchat and Instagram exhibited higher levels of body dissatisfaction. Interestingly, gender differences in these associations were not identified.

The circuit solution gives particular consideration to the loss of matching the output matching network. In pulse conditions, the PA can reach a maximum saturated output power of 43 dBm (20 W) with typical gain values of 18 dB and power‐added efficiency of 21%. The output power at −1 dB gain compression () is 40.2 dBm, and the power density is up to 3.36 W/mm in the active periphery under the drain voltage of 24 V. The chip is compact with an area of 5.6 × 3.7 mm2. This PA achieves higher output power in comparison to the reported PA MMIC.

Published: September 2024

AbstractThis article introduces a new, low cost and complexity, wideband Ku/K‐band combined low‐noise amplifier (LNA) Filter designed for large satellite phased array systems in advanced 22 nm Fully Depleted Silicon on Insulator Technology. The LNA achieves the required 20 dB gain through a two‐stage configuration using the cascode configuration. To effectively reject the transmitter (TX) signal, the LNA integrates 4 distributed parallel LC notch filters. Measured IP1dB at 29 GHz (TX band) demonstrates a 25 dB increase compared to IP1dB at 19 GHz (RX Band), with a remarkable 15 dB enhancement over the LNA without the filter. The 1‐dB gain bandwidth spans from 16 to 21 GHz, representing a 27% fractional bandwidth. Over the entire bandwidth, input/output return losses exceed 10 dB, maintaining a low noise figure (NF) of less than 3.5 dB. Inclusion of two filters at the input and middle of the first stage results in approximately 0.6 dB of increase in NF when compared to the LNA without the filter.

AbstractRespiratory motion‐induced image blurring and artifacts can compromise image quality in dynamic contrast‐enhanced MRI (DCE‐MRI) of the liver. Despite remarkable advances in respiratory motion detection and compensation in past years, these techniques have not yet seen widespread clinical adoption. The accuracy of image‐based motion detection can be especially compromised in the presence of contrast enhancement and/or in situations involving deep and/or irregular breathing patterns. This work proposes a framework that combines GRASP‐Pro (Golden‐angle RAdial Sparse Parallel MRI with imProved performance) MRI with a new radial sampling scheme called navi‐stack‐of‐stars for free‐breathing DCE‐MRI of the liver without the need for explicit respiratory motion compensation. A prototype 3D golden‐angle radial sequence with a navi‐stack‐of‐stars sampling scheme that intermittently acquires a 2D navigator was implemented. Free‐breathing DCE‐MRI of the liver was conducted in 24 subjects at 3T including 17 volunteers and 7 patients. GRASP‐Pro reconstruction was performed with a temporal resolution of 0.34–0.45 s per volume, whereas standard GRASP reconstruction was performed with a temporal resolution of 15 s per volume. Motion compensation was not performed in all image reconstruction tasks. Liver images in different contrast phases from both GRASP and GRASP‐Pro reconstructions were visually scored by two experienced abdominal radiologists for comparison. The nonparametric paired two‐tailed Wilcoxon signed‐rank test was used to compare image quality scores, and the Cohen's kappa coefficient was calculated to evaluate the inter‐reader agreement. GRASP‐Pro MRI with sub‐second temporal resolution consistently received significantly higher image quality scores (P < 0.05) than standard GRASP MRI throughout all contrast enhancement phases and across all assessment categories. There was a substantial inter‐reader agreement for all assessment categories (ranging from 0.67 to 0.89). The proposed technique using GRASP‐Pro reconstruction with navi‐stack‐of‐stars sampling holds great promise for free‐breathing DCE‐MRI of the liver without respiratory motion compensation.
From top to deep: An integrated multidisciplinary approach for the study of a transformative landscape of Savatra ancient city

Published: September 2024

AbstractIn this study, a combined workflow of computational methodologies is introduced to explore the transformative landscape of the ancient city of Savatra (Central Anatolia Region, Türkiye), which faces long‐term risks stemming from natural and anthropogenic threats. Emphasis was placed on regional and local scale landscape analysis, employing aerial and ground‐based remote‐sensing techniques to unravel past settlement patterns and understand the impact of environmental factors, topography and natural resources on both the location of Savatra and spatial organization of its features. On a regional scale, the influence of hydrological conditions, slope and aspect on the landscape was determined through the employment of Geographical Information System (GIS)‐based analysis of digital elevation models (DEMs). At a more local scale, the utilization of the Unmanned Aerial Systems‐derived DEM and geophysical survey helped identify potential archaeological features and also assessed the risk posed to these features. Furthermore, the incorporation of 3D GIS analysis, integrating 3D point cloud representations of the ground‐penetrating radar volume and DEM, provided essential insight into the state of preservation of the buried features. The collaborative application and joint interpretation of these methodologies yielded a wide range of clues and explanations, unravelling the complex palimpsest of past activities. This research not only serves as foundation for future studies specifically for Savatra, but also provides a preliminary remote sensing–based exploration blueprint to other yet to be studied archaeological sites.
Crosslinking Behavior of Ethylene‐Vinyl Acetate Copolymer Encapsulants in Dependence of the Additive Composition

Published: September 2024

ABSTRACTThe three‐dimensional crosslinking of encapsulants in photovoltaic (PV) modules significantly defines their thermomechanical properties and is usually initiated using peroxides and crosslinking accelerators. However, it has been shown that excess peroxides lead to undesirable side reactions such as browning, which is directly linked to the PV module power losses. Therefore, the encapsulant formulation should be adjusted accordingly, on the one hand, keeping the peroxide concentration possibly low and, on the other hand, enabling a sufficiently high gel content (GC). This work investigates the basic interaction of the crosslinking peroxide Luperox TBEC and the crosslinking accelerator Perkalink 301 (TAIC) with differential scanning calorimetry (DSC), to address this issue. In addition, their reaction potential with the antioxidant butylhydroxytoluene (BHT) is investigated. It is shown that stabilizing additives can have an influence on the peroxide crosslinking process, which can affect the resulting crosslinking state and require optimization of the lamination conditions. The additive content of commercial PV encapsulants is quantified using pyrolysis gas‐chromatography mass spectrometry (PY‐GCMS). Subsequently, a number of films with different TBEC and TAIC contents are produced, and their GC is analyzed as a function of the additive concentrations and lamination conditions. A range of formulations leading to a GC > 75% was identified which can be used as a guidance for encapsulant manufacturers.
School‐based motivational interviewing: Change and sustain talks during goal setting

Published: September 2024

AbstractThe student check‐up (SCU) is a brief school‐based motivational interviewing intervention developed to promote academic‐related behavioral changes and to increase accessibility to mental health services. Despite published randomized controlled trials demonstrating SCU's effectiveness in promoting student self‐efficacy in academic efforts, the SCU's impact on student grade outcome has been inconsistent across studies. This study examines whether student participants' written statements that represent change talk and sustain talk predict differences in post‐treatment grade outcomes and whether these effects are moderated by students' pre‐treatment academic achievement. In addition, we examine whether change and sustain statements mediate the relationship between study sites and grade outcomes. A two‐level linear regression controlling for pre‐treatment grades indicated that as the frequency of change statements increases, students' post‐treatment grades in English Language Arts decrease (B = −0.62, p = .03), suggesting that “the more” is not always “the merrier” when it comes to evoking change statements related to academic goals that require multiple behavioral changes for attainment.

ABSTRACTNatural antioxidants have been shown to be effective against atherosclerosis. Ginkgo flavone aglycone (GA) has strong antioxidant properties and can protect against endothelial damage. However, the mechanisms by which GA protects against atherosclerosis remain largely unexplored. This study hopes to find the anti‐atherosclerotic mechanism of GA. ApoE−/− mice fed a high‐fat diet were used for modeling atherosclerosis. The efficacy of GA on mice with atherosclerosis was evaluated based on the following indicators: Oil Red O staining, Masson staining, lipid content, and apoptosis. Transmission electron microscopy, Western blot, immunofluorescence staining, and propidium iodide staining were used to analyze the effects of GA on ox‐LDL‐treated human aortic endothelial cells. GA activated Nrf2 by promoting the nuclear translocation of Nrf2, thereby inhibiting endothelial pyroptosis. GA prevented endothelial pyroptosis suppressed oxidative stress, and inhibited the development of atherosclerosis in ApoE−/− mice fed high‐fat diets. At the cellular level, GA suppressed ox‐LDL‐induced pyroptosis of HAECs by reducing reactive oxygen species (ROS) levels and inhibiting NLRP3 inflammasome. Furthermore, siRNA targeting Nrf2 or ML385, an Nrf2 inhibitor, reversed these effects. GA liberated Nrf2 from Keap1 sequestration, enhanced the nuclear translocation of Nrf2 and the transcription of downstream antioxidant proteins, reinforced the antioxidant defense system, and inhibited oxidative stress, thereby preventing endothelial cell pyroptosis, and attenuating the progression of atherosclerosis. This study indicated that GA mitigated endothelial pyroptosis by modulating Keap1/Nrf2 interactions, shedding light on the potential mechanisms underlying the protective effects of natural antioxidants against atherosclerosis.

Published: September 2024

ABSTRACTUnderstanding invertebrate and fish responses to altered streamflows is important for water management that balances ecological function and societal needs. We studied the impacts of a significant water diversion on a stream food web, including benthic biofilms, benthic macroinvertebrates (BMI), and drifting macroinvertebrates. In the dry season, drift flux (number of aquatic individuals or biomass/s) and drift concentration (individual/m3) were lower below the diversion than above. Drift concentration (biomass/m3) was slightly higher below the diversion, due to the presence of large Trichopterans. All measures of drift dropped to nearly zero at the end of the dry season below the diversion, when streamflows were reduced by > 90% below the diversion relative to above, representing a significant loss of food resources for trout. Simultaneously, native Rainbow Trout (Oncorhynchus mykiss) switched from drift to benthic foraging 1 month earlier below the diversion as drift and water velocities declined. The ecology of the benthos was not as impacted by the diversion: BMI densities were higher below the diversion, while benthic biofilm densities were similar at the two sites. The taxonomic composition of BMI was also similar between the sites, but fewer Ephemeroptera entered the drift below the diversion. Overall, the late season decrease in drift below the diversion despite the similar or higher benthic production suggests that streamflows influence food availability for trout even in the absence of benthic responses. Reduced streamflows, due to water diversions as studied here, or due to climate change, will likely reduce food resources and growth opportunities for fishes.
