AbstractCarbonaceous materials have been considered the most promising anode in sodium‐ion batteries (SIBs) due to their low cost, good electrical conductivity, and structural stability. The main challenge of carbonaceous anodes prior to their commercialization is low initial coulomb efficiencies, derived from a lack of an efficient technique to reveal a fundamental comprehension of sodium storage mechanisms. Here, the direct observation of quasi‐Na metallic clusters in carbonaceous anodes during cycling through in situ XRD is reported. By means of such a technique, a strong self‐adsorption behavior forming quasi‐Na metallic clusters is detected within a rationally designed highly defective ultrathin carbon nanosheets (HDCS) anode. Such a self‐adsorption and crystalline system transformation mechanism in HDCS brings capacity retention about 100% after 1000 cycles at 1 A g−1. This work provides a new principle for designing high‐performance carbon anodes for SIBs.

Published: November 2024

AbstractThe field of technical textiles has grown significantly during the last two decades, with a focus on functionality rather than aesthetics. However, the advancement of NanoFusion technology provides a novel potential to combine better functionality and aesthetic value in textile finishes. NanoFusion incorporates nanoparticles into textile treatments to improve waterproofing, stain resistance, durability, and breathability. This is performed without affecting the textile's visual appeal or aesthetics and may even improve them. This textile finishing revolution is expected to impact industries such as athletics, outdoor clothing, car upholstery, and luxury fashion. It offers cutting‐edge functionality while maintaining style and design integrity. Furthermore, the use of nanoparticle textile coatings opens up new opportunities for personalization and modification. Manufacturers and designers can now experiment with different color combinations, patterns, and textured finishes while maintaining performance characteristics. NanoFusion technology has the potential to transform the textile industry by providing hitherto unattainable levels of performance and aesthetics. This study reviews the current state of the art in nanofinishes for garment textiles, focusing on their many varieties, techniques, mechanisms, and applications. In addition, it addresses significant concerns such as sustainability and the environmental footprint, paving the way for a new era in textile manufacturing.

AbstractThe collective rotations of oxygen octahedra play an important role in determining the physical properties of functional perovskite oxides. The epitaxial strain can serve as an effective means to modify the oxygen octahedral symmetry (OOS), i.e., oxygen octahedral rotation or tilt (OOR/OOT). However, the strain‐OOS coupling that may alter the details of the OOS, thereby the physical properties, has not been fully understood. In this work, it is demonstrated that epitaxial strain can not only induce a structural phase transition but also precisely tune the degree of OOR. The correlated metal CaNbO3, which is orthorhombic, is studied by growing as epitaxial thin films. By imposing epitaxial strain, it is found that the film undergoes a structural phase transition from orthorhombic to tetragonal upon fully straining (i.e., from a+b−b− to a0a0c−). In unstrained films, the octahedral rotation along the c‐axis is as large as 15.7° that can be tuned to 6.6° by strain. This finding offers a general approach to manipulating OOR/OOT via strain engineering in complex oxide heterostructures.
Bi‐Stable Metamaterials with Intrinsic Memory for Selective Wave Filtering Based on Frequency and Amplitude

Published: November 2024

AbstractAnalytical, numerical, and experimental methods are used to investigate the utility of metamaterials in controlling harmonic waves based on both their amplitude and frequency. By programming the metamaterials to support bi‐stable configurations (i.e., two stable phases), the required conditions are elucidated for a transition wave (i.e., a topological soliton) to nucleate due to harmonic excitation, causing a phase change within our metamaterial. As each of these phases has its own unique transmission frequency range, such phase change is harnessed to control harmonic waves based on both their amplitude and frequency. As a demonstration of principle, a low/high‐pass filter is shown by tuning the same metamaterial to change phase; from transmission to attenuation and vice versa. In addition, phase transitions taking place while preserving the metamaterial's state of attenuation or transmission are shown. Such materials can continue their functionality (i.e., either attenuation or transmission of waves) while keeping a record of extreme events that can cause their transition (i.e., have memory). These metamaterials can be useful in the next generations of advanced and functional acoustic devices.

Published: November 2024

AbstractHydrogel‐derived implants have proven value in bone tissue regeneration, and current efforts have concentrated on devising strategies for producing functional implants with desired structures and functions to improve therapeutic outcomes. Herein, a novel black phosphorus (BP) tagged responsive strontium (Sr) hydrogel particles are presented for bone defect repair. By applying microfluidic technology, Sr and carboxymethyl chitosan, and BP are integrated into poly(N‐isopropyl acrylamide) (pNIPAM) hydrogel matrix to generate such microparticles called pNBCSMs. Upon exposure to near‐infrared irradiation, the pNBCSMs experience volume shrinkage and provoke the extrusion of the incorporated Sr, ascribed to the photothermal conversion ability of BP and the thermosensitivity of pNIPAM. In vitro and in vivo experimental results reveal that pNBCSMs subjected to near‐infrared light display superior anti‐inflammatory, anti‐apoptotic, bacterial inhibitory, as well as osteogenesis‐promoting effects, thereby effectively improving defective cranial bone repair. These features suggest that the proposed pNBCSMs can be promising candidates for bone repair.

Published: November 2024

AbstractA theoretical study of an antiferromagnetically coupled spin system, specifically , characterized by a slightly distorted equilateral triangle configuration is presented. Using the Heisenberg model with exchange and Dzyaloshinskii–Moriya interactions, g‐factors, and an external magnetic field, three quantum machines are investigated using this system as the working substance, assuming reversible processes. For the magnetocaloric effect (MCE) is significant at low temperatures (1K) under a perpendicular magnetic field (). Although only the compound is considered, since the compound behaves quite similarly. How MCE influences the Carnot machine, which operates as a heat engine or refrigerator when varying the external magnetic field is analyzed. In contrast, the Otto and Stirling machines can operate as heat engines, refrigerators, heaters, or thermal accelerators, depending on the magnetic field intensity. The results indicate that enhanced MCE broadens the operating regions for these machines, with the Otto and Stirling machines primarily functioning as refrigerators and accelerators. The corresponding thermal efficiencies are also discussed for all operating modes.

AbstractThe sluggish reaction kinetics of the anodic oxygen evolution reaction (OER) and the inadequate catalytic performance of non‐noble metal‐based electrocatalysts represent substantial barriers to the development of anion exchange membrane water electrolyzer (AEMWE). This study performed the synthesis of a three‐dimensional (3D) nanoflower‐like electrocatalyst (CFMO) via a simple one‐step method. The substitution of Co with Fe in the structure induces a localized oxide path mechanism (LOPM), facilitating direct O−O radical coupling for enhanced O2 evolution. The optimized CFMO‐2 electrocatalyst demonstrates superior OER performance, achieving an overpotential of 217 mV at 10 mA cm−2, alongside exceptional long‐term stability with minimal degradation after 1000 h of operation in 1.0 M KOH. These properties surpass most of conventional noble metal‐based electrocatalysts. Furthermore, the assembled AEMWE system, utilizing CFMO‐2, operates with a cell voltage of 1.65 V to deliver 1.0 A cm−2. In situ characterizations reveal that, in addition to the traditional adsorbate evolution mechanism (AEM) at isolated Co sites, a new LOPM occurred around the Fe and Co bimetallic sites. First‐principles calculations confirm the LOPM greatly reduced the energy barriers. This work highlights the potential of LOPM for improving the design of non‐noble metal‐based electrocatalysts and the development of AEMWE.

AbstractHigh dark current density (Jd) severely hinders further advancement of near‐infrared organic photodetectors (NIR OPDs). Herein, we tackle this grand challenge by regulating molecular crystallinity and aggregation of fully non‐fused ring electron acceptors (FNREAs). TBT‐V‐F, which features fluorinated terminals, notably demonstrates crystalline intensification and a higher prevalence predominance of J‐aggregation compared to its chlorinated counterpart (TBT‐V‐Cl). The amalgamation of advantages confers TBT‐V‐F‐based OPDs with lower nonradiative energy loss, improved charge transport, decreased energetic disorder, and reduced trap density. Consequently, the corresponding self‐powered OPDs exhibit a 40‐fold decrease in Jd, a remarkable increase in detectivity (D*sh), faster response time, and superior thermal stability compared to TBT‐V‐Cl‐based OPDs. Further interfacial optimization results in an ultra‐low Jd of 7.30×10‐12 A cm−2 with D*sh over 1013 Jones in 320–920 nm wavelength and a climax of 2.2×1014 Jones at 800 nm for the TBT‐V‐F‐based OPDs, representing one of the best results reported to date. This work paves a compelling material‐based strategy to suppress Jd for highly sensitive NIR OPDs, while also illustrates the viability of FNREAs in construction of stable and affordable NIR OPDs for real‐world applications.

Published: November 2024

AbstractConstructing catalysts that simultaneously contain single atom/metal nanocluster active sites is a promising strategy to enhance the original catalytic behavior and accelerate the catalysis involving multi‐electron reactions or multi‐intermediates. Herein, the pyrolysis‐free synthetic method is developed to integrate single atoms and nanoclusters towards highly satisfactory catalytic performances for both acidic and alkaline hydrogen electrocatalysis. The controllable pyrolysis‐free strategy allows the precise modulation of the active centers, realizing the optimization of the adsorption energy and the regulation of the synergistic active components. Specially, the as‐prepared catalysts with hybrid single‐atom/nanocluster sites exhibited superior catalytic activities for hydrogen evolution in both acidic and alkaline media with low over‐potentials at −10 mA cm−2 of 25 mV and 8.6 mV, respectively, combining with outstanding durability towards high current density and methanol poisoning. This work developed a universal synthetic strategy for the single atom/nanocluster synergy systems and addressed the superiority of hybrid single‐atom/nanocluster sites.

Published: November 2024

AbstractCucurbalsaminones B (1) and C (2) are two abeo‐cucurbitane triterpenoids with a unique 5/6/3/6/5‐fused ring system and exhibit potent multidrug resistance (MDR)‐reversing activity. Herein, we report the first synthesis of these two natural products, both of them were accomplished in 14 steps from commercially available inexpensive resource compound lanosterol. Key features of this synthesis include a biomimetic tandem Wagner–Meerwein type lanostane‐to‐cucurbitane rearrangement followed by a bioinspired photochemical oxa‐di‐π‐methane (ODPM) rearrangement to complete the skeleton construction and an Eosin Y photoinduced Barton‐McCombie deoxygenation to realize the challenging oxidation state adjustment of the sterically hindered C11 position.

Published: November 2024

AbstractThe monolithic integration of III‐V semiconductors on Si emerges as a promising approach for realizing photonic integrated circuits. However, the performance and reliability of epitaxially grown devices on Si are hampered by the threading dislocation density (TDD) generated during the growth. In this study, the efficiency of a structure, combining III‐Sb‐based insertion layers and thermal annealing is evaluated, on the reduction of the emerging TDD in GaSb buffer layers grown on Si(001) substrates by molecular beam epitaxy. the impact of the thickness, composition, and number of the insertion layers is extensively explored. Then a detailed study of the annealing cycles with different conditions is conducted. A record TDD in the low 107 cm−2 for a 2.25 µm GaSb buffer grown on Si(001) is ultimately demonstrated.

Published: November 2024

AbstractDifferences in cognitive abilities affect search behaviors, but this has mostly been observed in laboratory experiments. There is limited research on how users search for information in real‐world, naturalistic settings and how real‐world search behaviors relate to cognitive abilities. In this study, we investigated a wide range of behavioral data captured from real‐life search tasks, their association with users' cognitive abilities, and the potential for automatically inferring cognitive abilities from these data. Furthermore, we aimed to determine the data quantity and monitoring duration needed to effectively estimate cognitive abilities from naturalistic behavior. Twenty individuals with βvarying cognitive abilities participated in the experiments in which their everyday search behavior was continuously recorded for 14 days. Their cognitive ability was evaluated through standard tests conducted individually. Data consisted of over 800 h of monitoring, including 2022 queries extracted from 1,442,447 screen frames and associated operating system logs. Using these data, naturalistic search behaviors were associated with cognitive abilities, and predictive models were trained. The results showed that lower selective attention was found to be associated with longer dwelling on selected search results. Faster psychomotor speed and higher fluid intelligence were found to be associated with a greater amount of text read on selected pages. Predictive models exhibited small error rates in predicting cognitive abilities.

Published: November 2024

AbstractA novel adaptive distributed estimation algorithm is developed for dynamic average consensus problem. The algorithm enables a group of agents to accurately track the average value of signals that are available locally to each agent. Unlike most of existing approaches that rely on error transformation techniques, our algorithm employs an adaptive‐gain based barrier function to simultaneously meet prescribed performance specifications of transient and steady state. It is both simple and easy to implement and is not dependent on bounded reference signals and their derivatives. Additionally, it can operate under less strict assumptions than those that assume absolute bounds on the signals. Simulation results are presented to demonstrate the effectiveness of the developed algorithm.

AbstractAdvanced coatings for improving the electro‐chemo‐mechanical stability of high‐capacity, layered Ni‐rich oxide cathode materials play an important role in modern battery technology. Vanadium‐based protective coatings are particularly promising owing to their ability to provide high ionic conductivity and their intrinsic robustness. In addition, diminishing or eliminating residual lithium through surface coating shows great promise in mitigating capacity loss and addressing associated challenges. Herein, we report on a strategic exploration of a facile coating approach for Ni‐rich LiNixCoyMn1−x−yO2 (NCM851005, 85 % Ni content) utilizing polyoxovanadate. Specifically, TBA3H3[V10O28] was applied due to its solubility in non‐aqueous media, avoiding H2O‐induced side reactions and achieving a more uniform surface coverage. The cycling performance of NCM851005 before and after modification was tested in conventional Li‐ion cells, as well as in all‐solid‐state batteries with a lithium thiophosphate superionic electrolyte. Our findings highlight the potential of polyoxovanadate‐derived protective coatings for improving the cyclability of Ni‐rich cathodes.

ABSTRACTA key contemporary challenge is enhancing the value of agro‐industrial byproducts. Cellulose, the most abundant renewable resource, offers significant industrial potential due to its versatile properties. Produced in its pure form by various bacteria, cellulose is increasingly utilized in microscale and nanoscale fibers for composite reinforcement. In this study, cellulose microfibers were derived from palm sprout fibers through a series of treatments like pretreatment, high‐pressure hydrolysis in an autoclave, and bleaching. These fibers were then characterized using techniques such as UV spectroscopy, FTIR, SEM, and XRD. The study evaluated the antibacterial properties of the treated cellulose microfibers against both gram‐positive Staphylococcus aureus (07%) and gram‐negative Escherichia coli (10%), finding higher effectiveness against E.coli. Additionally, the microfibers exhibited a lower EC50 value of 0.101 mg/mL, suggesting that although the microfiber extract is effective, the standard antioxidant is somewhat more potent. Adsorption studies revealed that the cellulose microfibers followed the Langmuir isotherm model, with a high determination coefficient of 0.998, and reached maximum dye adsorption for RB 160 within 120 min. In this adsorption study, 50 mg of dye was removed. These results indicate that the treated cellulose microfibers are a promising biosorbent for improving dye removal processes.
Validated Spectrofluorometric Assay for Folic Acid Determination in Pure and Pharmaceutical Forms via Basic Fuchsin Fluorescence Quenching
Authors: Qader Aryan Fathulla 
Published: November 2024

ABSTRACTA simple, specific, sensitive, rapid, and cost‐effective spectrofluorometric method for quantifying folic acid has been developed using basic fuchsin as a fluorescence quenching agent. This method relies on the quenching effect of folic acid on the inherent fluorescence of basic fuchsin, facilitated by their interaction in Britton–Robinson buffer solution at pH 9, leading to the formation of an ion‐associated complex. The decrease in fluorescence intensity of basic fuchsin was measured at 730 nm, with excitation at 365 nm. The method demonstrated a linear relationship (R2 = 0.9977) between the quenching fluorescence intensity (ΔF) and folic acid concentration over the range of 4–20 μg/mL, with a detection limit of 0.17 μg/mL. The method showed no significant interference from common excipients found in pharmaceutical tablets. The results obtained were in good agreement with those from high‐performance liquid chromatography, with no significant differences in precision or accuracy. This spectrofluorimetric method was successfully applied to determine the folic acid content in various commercial pharmaceutical tablets.
Biodiversity risk and firm performance: Evidence from US firms
Authors: Bach Thang Ngoc , Hoang Khanh , Le Thanh 
Published: November 2024

AbstractBiodiversity loss is considered as a critical global challenge with significant implications for ecosystems, economies, and societies. While the importance of biodiversity conservation is widely acknowledged, the extent to which biodiversity risk impacts firm performance remains an under‐explored area of research. This paper examines how biodiversity risk affects firm performance using a new measure of firm‐level biodiversity risk generated from textual analysis of firms' 10‐K reports. Our multivariate analysis shows that biodiversity risk significantly hinders performance of firms in the United States during the 2001–2021 period. The finding holds well after controlling various confounding factors, using alternative variable measurements, model specifications, and correcting for endogeneity problems in the biodiversity risk‐firm performance nexus. Besides decreasing sales growth and profitability, biodiversity risk increases in the cost of goods sold, as explained by the Cobb–Douglas production function. Interestingly, we find that the effect is stronger for firms in biodiversity‐sensitive industries, weaker for firms with more product innovation, and remains insignificant for firms with top‐tier performance. Our study provides policy and practical implications for businesses to mitigate biodiversity risk in this contemporary era of ecological degradation.
