Dynamic Chiral Folding for Arene-Perfluoroarene Force Driven Clamping.

Peptide folding provides a feasible protocol to design intelligent chiral supramolecular systems toward sensing, recognition, and many other advanced functions. Here we conjugated dual short peptide arms on the aromatic core in a spatially close manner, allowing for intramolecular folding. Through controlling the aromatic core skeleton and appended luminophores, efficient chirality transfer to terminal pyrenes was realized. The through-space transferred chirality exhibited ultrahigh sensitivity toward solvent environments. Micropockets within dipeptides would accommodate the solvents specifically to initiate the chiroptical inversion expressed in the ground-state circular dichroism and the circularly polarized luminescence at photoexcited states. The dynamics also were depicted on the selective binding of guests through arene-perfluoroarene interactions. We successfully constructed a dynamic peptide-based clamp that could control the endo- and exo-type arene-perfluoroarene complexation. This work inspires the design and fabrication of peptide-based chiroptical materials with adaptability to external fields.

Broad Tuning of Paper Microfluidic Properties by Covalent Surface Modification for Precise Flow Control and Sensing.

In an effort to innovate on-site sensing platforms for a wide range of analytes in different matrices, microfluidic paper-based devices (μPADs) are promising candidates to bring the lab to the sample, as they allow passive, capillary-action-driven flow. Their use, however, is somewhat limited by the fact that the integration of advanced functionality and flow control is difficult. Although recent progress in this area has led to the development of on/off-valving and timing control of flow by changing the chemical and physical properties of paper, precise control over flow in paper microfluidics remains challenging. Here, we propose the use of a simple covalent modification of cellulose paper to tune its surface properties, thereby introducing a broad range of functionality and applicability. For this purpose, fatty acyl chlorides with different chain lengths were used as hydrophobic reagents to change the surface properties. The modified paper was characterized by FTIR-ATR, static water contact angle measurements, and capillary flow properties (permeability, maximum flow distance, and flow rate). The produced papers were then applied in several proof-of-concept devices to demonstrate their potential in sensing and actuating for improved on-site analysis. We demonstrate how precisely modified paper can be used for surface tension measurements and multistep valving based on its wickability for solutions of varying surface tensions, for the determination of ethanol concentration in water by monitoring the maximum flow distance in a 3D-printed device, and for the optimization of on-paper liquid-liquid extraction via fine-tuned control of capillary flow rates.

Cobalt ferrite nanoparticles: The physics, synthesis, properties, and applications

Spinel cobalt ferrite (CoFe2O4, CFO) nanoparticles (NPs) are a major focus of fundamental science and technological innovation due to their distinctive mix of magnetic, electrical, and chemical characteristics. CFO NPs have outstanding chemical stability, modest saturation magnetism (∼80 emu/g), a high Curie temperature (∼793 K), and significant magnetocrystalline anisotropy. These characteristics, further improved by cation substitution and surface functionalization, enable a wide range of applications. This review provides a comprehensive analysis of CFO NPs, covering their synthesis methods, physicochemical characterization, surface modifications, and diverse applications. We compare the environmental impact, scalability, yield, and particle size control of a variety of synthesis techniques, including co-precipitation, hydrothermal, sol-gel route, combustion method, microemulsion, thermal decomposition, electrochemical synthesis, polyol method, and green synthesis methods. The sustainable alternative of green synthesis, which employs plant- and microbe-mediated biosynthesis, is becoming increasingly important in the biomedical and environmental sectors. Furthermore, we explore advanced surface functionalization techniques that employ monomeric, inorganic, and polymeric stabilizers to improve the biocompatibility and stability of CFO NPs. The effects of cation substitution (such as transition metals and rare-earth dopants) on the physicochemical and magnetic properties of CFO NPs are examined in detail, addressing challenges like cost and stability in real-world applications. Moreover, the present review provides a detailed discussion correlating structural, morphological, magnetic, dielectric, optical, and electrical properties of CFO with synthesis methods and modifications. The traditional energy storage and conversion applications of CFO are comprehensively discussed. Additionally, the review highlights magnetic applications, biomedical applications (e.g., MRI contrast agents, magnetic hyperthermia, and biosensors), the role of CFO in electronics and optoelectronics, purification and catalysis applications, as well as advances in electromagnetic technologies. Emerging applications, including their roles in quantum computing, nanorobotics, tissue engineering, and bioimaging, are also discussed, emphasizing the cutting-edge potential of CFO NPs in multifunctional technologies. The objective of this review is to critically evaluate recent advancements, challenges, and future research directions to bridge the divide in understanding CFO NPs. This systematic evaluation establishes a strong foundation for researchers, allowing them to investigate novel applications of CFO NPs in both current and emerging technological domains.

Prefrontal cortex activity during binocular color fusion and rivalry: an fNIRS study

IntroductionUnderstanding how the brain processes color information from both the left and right eyes is a significant topic in neuroscience. Binocular color fusion and rivalry, which involve advanced cognitive functions in the prefrontal cortex (PFC), provide a unique perspective for exploring brain activity.MethodsThis study used functional near-infrared spectroscopy (fNIRS) to examine PFC activity during binocular color fusion and rivalry conditions. The study included two fNIRS experiments: Experiment 1 employed long-duration (90 s) stimulation to assess brain functional connectivity, while Experiment 2 used short-duration (10 s) repeated stimulation (eight trials), analyzed with a generalized linear model to evaluate brain activation levels. Statistical tests were then conducted to compare the differences in brain functional connectivity strength and activation levels.ResultsThe results indicated that functional connectivity strength was significantly higher during the color fusion condition than the color rivalry condition, and the color rivalry condition was stronger than the Mid-Gray field condition. Additionally, brain activation levels during binocular color fusion were significantly greater, with significant differences concentrated in channel (CH) 12, CH13, and CH14. CH12 is located in the dorsolateral prefrontal cortex, while CH13 and CH14 are in the frontal eye fields, areas associated with higher cognitive functions and visual attention.DiscussionThese findings suggest that binocular color fusion requires stronger brain integration and higher brain activation levels. Overall, this study demonstrates that color fusion is more cognitively challenging than color rivalry, engaging more attention and executive functions. These results provide theoretical support for the development of color-based brain-computer interfaces and offer new insights into future research on the brain's color-visual information processing mechanisms.

Modeling and analysis of driving behavior at intersections considering the signal countdown provided by vehicle navigation systems

Vehicle navigation systems provide drivers with real-time remaining signal time information from a significant distance away from intersections, enabling them to adjust their driving behaviors proactively. The advanced navigation function has established a new paradigm for driving behavior and traffic flow. This study first examines the alterations in driving behavior resulting from the signal countdown of vehicle navigation systems (SCVNS) and integrates these effects into the car-following model. Second, the study investigates the modifications in driving behavior induced by SCVNS using the full velocity difference (FVD) model, focusing on its implications for traffic efficiency, safety and environmental impact. Finally, the study quantifies the influence of key parameters in the model on traffic flow and validates the effects of SCVNS across different car-following models. The results indicate that SCVNS enables vehicles to adjust their driving behavior proactively, enhancing traffic efficiency at intersections and reducing the risk of rear-end collisions, although it may slightly increase emissions. Additionally, the effects of SCVNS are validated across various car-following models.

IDOM: Statistical analysis of dissolved organic matter characterized by high‐resolution mass spectrometry

AbstractDissolved organic matter (DOM) contains thousands of molecules and is key for biogeochemical cycles in aquatic and terrestrial ecosystems by interacting with microbes. Over the last decade, the study of DOM has been advanced and accelerated with the developments of instrumental and statistical approaches. However, it is still challenging in statistical analyses, data visualization, and theoretical interpretations largely due to the complexity of molecular composition and underlying ecological mechanisms. In this study, we developed an R package iDOM with functions for the basic and advanced statistical analyses and the visualization of DOM derived from Fourier transform ion cyclotron resonance mass spectrometer (FT‐ICR MS). The package could handle various data types of DOM, including molecular compositional data, molecular traits, and uncharacterized molecules (i.e., dark matter). It could integrate explanatory data, such as environmental and microbial data, to explore the relationships between DOM and abiotic or biotic drivers. To illustrate its use, we presented case studies with an example dataset of DOM and microbial communities under experimental warming. We included case studies of basic functions for the calculation of molecular traits, the assignment of molecular classes, and the compositional analyses of chemical diversity and dissimilarity. We further showed the case studies with advanced functions to quantify DOM assembly processes, assess the effects of dark matter on molecular interactions, analyze the ecological networks between DOM and microbes, and explore their response to warming. The source code and example dataset of iDOM are publicly available on https://github.com/jianjunwang/iDOM. We expect that iDOM will serve as a comprehensive pipeline for DOM statistical analyses and bridge the gap between chemical characterization and ecological interpretation in a theoretical framework.

Geometrical design of 3D superconducting diodes

The design of advanced functionality in superconducting electronics usually focuses on materials engineering, either in heterostructures or in compounds of unconventional quantum materials. Here we demonstrate a different strategy to bespoke function by controlling the 3D shape of superconductors on the micron-scale. As a demonstration, a large superconducting diode effect is engineered solely by 3D shape design of a conventional superconductor, ion-beam deposited tungsten. Its highly efficient diode behavior appears from its triangular cross-section when vortices break time-reversal and all mirror symmetries. Interestingly reciprocity is observed at four low-symmetry field angles where diode behavior would be expected. This can be understood as a geometric mechanism unique to triangular superconductors. Geometry and topology induce a rich internal structure due to the high-dimensional tuning parameter space of 3D microstructures, inaccessible to the conventional 2D design strategies in thin films.

Self‐Assembly of Silver Nanoclusters by Cooperative Acetylene Bonding with Mutual Pyridyl Coordination

The controlled supramolecular alignment of atomically precise metal nanoclusters is a promising method to unlock unprecedented properties and advanced functions beyond those of the individual monomeric nanoclusters. Conventional protocols for the construction of such assemblies require the use of two or more types of ligands for protecting and interconnecting the nanoclusters, respectively. Herein, a strategy is demonstrated for the hierarchical self‐assembly of an alkyne‐protected silver nanocluster into a 3D network in the crystalline lattice based on cooperative silver···acetylene coordination and silver···pyridyl coordination by a bifunctional ligand with a simple design. The bent ligand L produces a Cl@Ag14L12 monomer with a helical conformation resembling that of organic tripodal ligands, which assembles into a 3D network as evident from a single‐crystal X‐ray diffraction analysis. The monomeric and network structures are further characterized using grazing‐incidence small‐angle X‐ray scattering, atomic force microscopy, X‐ray photoelectron spectroscopy, and X‐ray absorption fine structure, in addition to photoluminescence with a microsecond lifetime in the solid state, exhibiting the success of the strategy toward the design of self‐assembled 3D supramolecular arrangements of atomically precise metal nanoclusters using a single, simple ligand.

Intelligent control of robotic X-ray devices using a language-promptable digital twin.

Natural language offers a convenient, flexible interface for controlling robotic C-arm X-ray systems, making advanced functionality and controls easily accessible.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name). Author 1 Given name: [Benjamin D.] Last name [Killeen]. Also, kindly confirm the details in the metadata are correct. However, enabling language interfaces requires specialized artificial intelligence (AI) models that interpret X-ray images to create a semantic representation for language-based reasoning. The fixed outputs of such AI models fundamentally limits the functionality of language controls that users may access. Incorporating flexible and language-aligned AI models that can be prompted through language control facilitates more flexible interfaces for a much wider variety of tasks and procedures. Using a language-aligned foundation model for X-ray image segmentation, our system continually updates a patient digital twin based on sparse reconstructions of desired anatomical structures. This allows for multiple autonomous capabilities, including visualization, patient-specific viewfinding, and automatic collimation from novel viewpoints, enabling complex language control commands like "Focus in on the lower lumbar vertebrae." In a cadaver study, multiple users were able to visualize, localize, and collimate around structures across the torso region using only verbal commands to control a robotic X-ray system, with 84% end-to-end success. In post hoc analysis of randomly oriented images, our patient digital twin was able to localize 35 commonly requested structures from a given image to within mm, which enables localization and isolation of the object from arbitrary orientations. Overall, we show how intelligent robotic X-ray systems can incorporate physicians' expressed intent directly. Existing foundation models for intra-operative X-ray image analysis exhibit certain failure modes. Nevertheless, our results suggest that as these models become more capable, they can facilitate highly flexible, intelligent robotic C-arms.

Strain-Assisted Large-Scale 1T-MoS2 Synthesis and its Optical Synaptic Flash Memory Application.

2D transition-metal dichalcogenides (TMDCs) have attracted attention as promising materials for next-generation devices owing to their versatile electronic and optical properties. The phase variety of TMDCs provides strategic opportunities for performance enhancement. Herein, a novel method is proposed to synthesize wafer-scale 1T phase MoS₂ and, simultaneously, induce a phase transition via a plasma-assisted metal-sulfidation process and spontaneous internal strain. With thicker MoS2 layers, the strong internal strain during synthesis suppresses the undesirable phase transition from the metastable 1T phase to the 2H phase, ensuring stabilization of the 1T phase. Furthermore, as-synthesized 1T-MoS₂ shows remarkable electrical properties owing to the narrow bandgap (0.4eV) of its semi-metallic state. As a result, the 1T-phase MoS₂ floating gate (1T-FG) flash memory demonstrates a wider memory window, a higher on/off ratio, and improved stability compared to the 2H-phase MoS₂ floating gate (2H-FG) flash memory. A 5 × 5 array structure is constructed to validate large-scale integration. Notably, under light irradiation, a single 1T-FG memory enables carrier trapping in the floating gate, even in the off state. This study introduces a facile phase control strategy and provides insights into advanced nonvolatile memory and optoelectronic synaptic functionalities.

Enhancing cost efficiency and promoting sustainable development of rapeseed in China: the role of scale operations and management

IntroductionEnhancing cost efficiency and minimizing production expenses are pivotal for the long-term sustainability of China’s rapeseed industry. This study takes a comprehensive approach by integrating the Cobb–Douglas production function model with an advanced cost function model to empirically assess the influence of farm operation scale on the cost efficiency of rapeseed cultivation. Results reveal a non-linear relationship between the scale of operation and the average cost per mu: as the operational scale expanded, the average cost per mu initially decreased, then increased. Furthermore, economies of scale exhibit regional and topographical heterogeneity.MethodsDrawing on a robust dataset from 3,144 farmers across 14 key rapeseed-producing provinces in China, spanning from 2018 to 2021, our analysis uncovers a nuanced relationship between operational scale and production costs.Results and discussionThe findings indicate that as the scale of operation increases, the unit production cost initially declines, reaching a critical threshold before rising again, reflecting shifts in the production cost structure. This pattern is mirrored in the average cost efficiency loss per kilogram of rapeseed, which also shows an initial decrease followed by a subsequent increase. An analysis of regional heterogeneity reveals that in the eastern plains, the expansion of farm scale effectively curtails the excessive use of labor and seed inputs, leading to greater cost efficiency. Moreover, the findings also reveal that cost efficiency losses are consistently lower in the eastern regions compared to their central and western counterparts, and similarly, plains regions outperform non-plains regions in terms of cost efficiency. These insights offer valuable implications for policymakers and agricultural stakeholders aiming to optimize production practices and enhance the economic sustainability of rapeseed farming in China.

Adoption of Large Language Model AI Tools in Everyday Tasks: Multisite Cross-Sectional Qualitative Study of Chinese Hospital Administrators.

Large language model (LLM) artificial intelligence (AI) tools have the potential to streamline health care administration by enhancing efficiency in document drafting, resource allocation, and communication tasks. Despite this potential, the adoption of such tools among hospital administrators remains understudied, particularly at the individual level. This study aims to explore factors influencing the adoption and use of LLM AI tools among hospital administrators in China, focusing on enablers, barriers, and practical applications in daily administrative tasks. A multicenter, cross-sectional, descriptive qualitative design was used. Data were collected through semistructured face-to-face interviews with 31 hospital administrators across 3 tertiary hospitals in Beijing, Shenzhen, and Chengdu from June 2024 to August 2024. The Colaizzi method was used for thematic analysis to identify patterns in participants' experiences and perspectives. Adoption of LLM AI tools was generally low, with significant site-specific variations. Participants with higher technological familiarity and positive early experiences reported more frequent use, while barriers such as mistrust in tool accuracy, limited prompting skills, and insufficient training hindered broader adoption. Tools were primarily used for document drafting, with limited exploration of advanced functionalities. Participants strongly emphasized the need for structured training programs and institutional support to enhance usability and confidence. Familiarity with technology, positive early experiences, and openness to innovation may facilitate adoption, while barriers such as limited knowledge, mistrust in tool accuracy, and insufficient prompting skills can hinder broader use. LLM AI tools are now primarily used for basic tasks such as document drafting, with limited application to more advanced functionalities due to a lack of training and confidence. Structured tutorials and institutional support are needed to enhance usability and integration. Targeted training programs, combined with organizational strategies to build trust and improve accessibility, could enhance adoption rates and broaden tool use. Future quantitative investigations should validate the adoption rate and influencing factors.

Hyaluronic acid as a versatile building block for the development of biofunctional hydrogels: In vitro models and preclinical innovations.

Hyaluronic acid (HyA) is a non-sulphated linear polysaccharide found abundantly in the extracellular matrix, known for its biocompatibility and versatility in tissue engineering. Chemical modifications of HyA, including methacrylate, acrylate, click chemistry, norbornene, or host-guest chemistry, are necessary for the formation of stable hydrogels with tuneable biophysical characteristics. These modifications enable precise control over stiffness, swelling, degradation, and advanced functionalities such as shear-thinning, self-healing, and injectability. Functionalisation further enhances hydrogel bioactivity, enabling controlled cell adhesion, modulation of cell behaviour, hydrogel degradation, and release profiles, as well as inflammation modulation or bacterial growth inhibition. These are achieved by conjugating proteins, peptides, antibodies, or reactive chemical groups. HyA hydrogels find broad applications both in vitro and in vivo. In vitro, HyA-based hydrogels can support the development of models to understand fundamental processes in health and mechanisms behind disease progression, serving as highly tuneable extracellular matrix mimetics. As therapeutic interventions, injectable or implantable HyA-based hydrogels have been developed to repair a range of tissues, including cartilage, bone, muscle, and skin defects. However, issues remain to be addressed before widespread adoption of HyA-based hydrogels as clinical options. Future innovations for HyA hydrogels include its establishment as an enabling technology for the delivery of novel therapeutics, with a particular focus on immunomodulatory molecules, and the development of more dynamic, tissue-mimetic HyA-based hydrogels.

In Situ Control of Reactive Mesogens Alignment During 3D Printing by Two-Photon Lithography.

Photopolymerizable liquid crystals, also known as reactive mesogens, are leading candidates for additive manufacturing of smart microdevices via two-photon lithography (TPL). While substantial advancements are made toward innovative applications, precise control of molecular alignment during fabrication, essential for tailoring complex optical and mechanical responses, remains a significant challenge. Current solutions require elaborate multi-step procedures or customized setups to achieve 2D or 3D alignment patterns. Herein, the deterministic effect of TPL on the orientation of mesogenic moieties is reported, under optimized printing conditions. Specifically, a single-step simple method is developed for aligning the nematic director in situ, with sub-diffraction-limited resolution, during 3D printing. Based on the conventional TPL workflow, the "director-tuning mode" (DiTuM) relies on the anisotropic photopolymerization reaction occurring along the print path at low laser scan speeds (≈0.1mms-1). A TPL-induced "easy axis" arises for the mesogenic moieties, programmable in direction and strength, and competes with the initial alignment to create potentially convolute 3D director fields. The method holds considerable promise for 3D/4D printing, enabling advanced functionalities, and offers a robust platform for anti-counterfeiting applications, leveraging the unique optical signatures generated by complex microstructures.
