Published: January 2025

AbstractDentin hypersensitivity (DH), caused by the exposure of dentin tubules, is a common complaint of dental patients. Although occlusion of the exposed tubules is the primary treatment approach, the complex oral environment, and multiple simultaneous requirements often hinder its implementation. In this study, strawberry‐shaped hemispheric Janus particles (JPs) are synthesized, and their use in the treatment of DH is evaluated in vitro and in an animal model. The hemispheric side of the JPs is modified with polymers of quaternary ammonium salts (QASs) to form a superhydrophobic coating with antibiofilm properties, while the flat side is modified with catechol groups able to form strong bonds with dentin. Even after 1 h of ultrasonication or 1000 rounds of thermal cycling, the dentin tubules are completely occluded by the JPs. Moreover, biofilm formation is not observed, and the area of living bacteria is less than 1% compared to the blank control and sodium fluoride (NaF)‐treated groups. In a rat model, the dentin tubules in the fixed specimens are completely occluded at day 3, much earlier than the occlusion obtained with commonly used NaF. These results demonstrate that JPs can provide a novel approach to the treatment of DH.

Published: January 2025

AbstractMoiré materials exhibit diverse quantum properties such as superconductivity and correlated topological phases, making them ideal for studying strongly correlated systems. While moiré materials are typically formed by stacking 2D materials with interlayer interaction dominated by weak van der Waals (vdW) forces, constructing moiré covalent superlattices by fluorinating twisted bilayer graphene becomes possible. With first principles calculations, it is demonstrated that fluorination of twisted bilayer graphene (TBG) can induce covalent bonds between adjacent layers, transforming the vdW‐dominated interactions. This results in enhanced modulation of the electronic structure, with abundant flat bands across the spectrum. The findings suggest that covalent moiré superlattices offer new platforms for exploring correlated quantum phenomena and moiré covalent chemistry.

AbstractMultispectral infrared imaging can acquire spectral information that is not attainable from single band photodetectors. While emerging nanomaterials such as colloidal quantum dots and 2D materials are heavily studied to realize dual‐band photodetectors by stacking them vertically, no device has yet demonstrated high detectivity with high response speeds. In this work, bias‐tunable, two‐terminal dual‐band photodetectors are demonstrated that can cover short‐wavelength and mid‐wavelength infrared at 300 K. A metamorphic barrier is developed to connect short and mid‐wave infrared back‐to‐back diodes while simultaneously providing photocarrier trap states for dislocation‐assisted photoconductive gain for mid‐infrared detection. The high specific detectivity of 3.8 × 1010 Jones and rapid response speeds of ≈2 µs are achieved in the mid‐wavelength infrared channel by precise control of metamorphic barrier and absorber thickness. This device is fully compatible with readout integrated circuits, making it a promising candidate for next‐generation multispectral infrared imaging.

AbstractImmediate hemostasis and effective treatment are foremost for acute intervention in traumatic brain injury (TBI), but the therapeutic tools and professional treatment methods are often lacking at the scene. Self‐gelling powders formed by the self‐assembly of pure molecular drugs can quickly deliver hemostatic and therapeutic effects without complications from chemical modifications or additional carriers. However, no clinical drugs have been reported as a self‐gelling powder for this purpose. Here, a self‐gelling powder is self‐assembled from sodium aescinate (SA), a drug already approved for treating trauma. To generate SA self‐gelling powder (SA self‐gel‐P), SA powder is heated and cooled in an alkaline solution to form a hydrogel, then freeze‐dried and ground. The obtained SA self‐gel‐P has a good hydrophilicity. When sprayed onto the bleeding site after TBI, it rapidly absorbed blood and formed a gel through intermolecular hydrogen bonding, facilitating effective in situ sealing and rapid hemostasis. Furthermore, the formed hydrogel released SA over a long period, which helped reduce neuronal death, improve integrity of the blood‐brain barrier, reduce brain edema, alleviate neuroinflammation, and ultimately promote recovery of neurofunction without significant toxic side effects. This self‐gelling powder may serve as a powerful auxiliary tool for the pre‐hospital treatment of TBI.

AbstractFerroptosis is a newly identified type of regulated cell death characterized by iron‐dependent lipid peroxidation. Among the main ferroptosis‐suppressing systems, the dihydroorotate dehydrogenase (DHODH)‐ ubiquinone axis is closely related to mitochondria and energy metabolism, implying that the axis protects cells from oxidative stress damage via the maintenance of redox homeostasis. However, ferroptosis initiation requires a suitable oxidative environment and a breakthrough in redox homeostatic limitations by ferroptosis‐suppressing systems. Hence, the nanoparticles are rationally engineered to achieve efficient ferroptosis induction by releasing dual‐release free iron and disrupting ferroptosis‐suppressing systems. Atovaquone (ATO)‐loaded hollow mesoporous etching zeolitic imidazolate framework‐67 double‐coated iron oxide/calcium phosphate (Fe3O4/CaP) is conjugated with polyethylene glycol. The external double‐coated Fe3O4/CaP structure enhances the efficiency of multiple reactive oxygen species (ROS) generation promoting oxidative stress. Still, it achieves free iron dual‐release to increase the content of unstable iron pools for igniting the ROS storm and lipid peroxidation spark. The release of ATO not only affects the energy metabolism of the mitochondrial respiratory chain by binding to complex III but also downregulates DHODH to restrict the ubiquinol system to disrupt the ferroptosis‐suppressing systems. Therefore, the design of this composite nanomedicine provides an approach for inducing ferroptosis and a theoretical basis for clinical ferroptosis anti‐tumor trials.

AbstractBio‐based polyethylene furandicarboxylate (PEF) plays a vital role in high‐performance packaging material for plastic replacement. However, the poor toughness blocks its practical applications. Copolymerization modification can enhance the toughness of PEF but inevitably causes a decrease in strength and barrier properties. Although nanofillers can enhance the overall performance of PEF, the intrinsic incompatibility between inert inorganic nanomaterials and PEF leads to poor reinforcement effects. Herein, a polydopamine (PDA) nanosheets/poly(ethylene‐co‐1,4‐cyclohexanedimethylene 2,5‐furandicarboxylate) (PECF) (denoted as PDAP) composite polyester is developed through the regulation of molecular and interface structures. The strategy realizes the in situ entanglement of nanofillers with the PECF chain segments through interface hydrogen bonding. The structure enhancement by molecular copolymerization and the interface enhancement by reinforcements promote crystallization, orientation, and bridging of composite systems, respectively. Benefiting from this multi‐scale, multi‐dimensional, and multi‐component synergistical design, the resultant PDAP integrates high strength (85 MPa), high toughness (111%), and excellent gas barrier properties (i.e., O2 0.016 barrer, CO2 0.013 barrer, and H2O 1.4×10−14 g cm cm−2 sPa) that are much higher than bio‐based materials and most engineering plastics. Interestingly, such the PDAP also shows superior physical recyclable, UV‐shielding, and solvent‐resistant properties, making it promising competitive for plastic replacement for high‐performance and multifunctional packaging materials.

AbstractStimuli‐responsive programmable materials exhibit remarkable potential for smart applications due to their ability to attain multi‐stable states through structural adaptability upon guest molecule removal or exchange. However, achieving designability remains challenging, particularly in maintaining the crystallinity for single‐crystal‐to‐single‐crystal (SCSC) transformations and ensuring tunable activation. In this study, it is demonstrated that programmable SCSC transformations between an empty monoclinic framework and an empty triclinic framework can be manipulated through the stimuli combining various activations and guest molecules. Reversible empty framework switching is facilitated by MeOH adsorption and heating‐induced SCSC transformations, whereas H2O adsorption alone cannot directly induce structural transformation. Instead, the empty monoclinic framework must first adsorb N,N‐Dimethylformamide (DMF) molecules to form a new DMF‐adsorbed framework and subsequently undergoes H2O adsorption and mild activation to yield the empty triclinic framework. These interconvertible frameworks differ in their photothermal conversion performance and selectively cause discoloration of CuSO4·5H2O due to dehydration. Photothermal temperatures ultimately induce the transformation to the empty monoclinic framework, attaining temperatures up to 640 K within 15 s under 808 nm laser irradiation (1.7 W cm−2). Potential energy calculations and single‐crystal data reveal that the programmable structural adaptability is driven by the varying affinities of pore environments for different guest molecules.

AbstractThe anomalous Hall effect (AHE) occurs in magnetic systems and also unexpectedly in non‐magnetic materials adjacent to magnetic insulators via the heterointerface interactions. However, the AHE in heterostructures induced by the magnetic proximity effect remains quite weak, restricting their practical device applications. Here, a large intrinsic AHE with a resistivity of 114 nΩ cm at 5 K in noncoplanar magnetic heterostructures of Cr5Te6/Pt is reported. This is the record‐high AHE value among all the magnetic insulators/heavy metal heterostructures. A reversal of the AHE signal occurs due to the reconstruction of Berry curvature at the Fermi level, which is verified by the first‐principles calculations. Topological spin textures at the interface are directly visualized via high‐magnetic‐field magnetic force microscopy, which accounts for the large AHE, as confirmed by the atomic simulations. These findings open a new avenue for exploring the large AHE in heterointerfaces and facilitate the potential applications in topological spintronic devices.

AbstractImage processing has become a quintessential data‐intensive computational task, and leveraging sensors with real‐time image processing has been focused for the development of photodetectors. However, managing responsivity normally needs an additional gate voltage, which seriously limits the application in the resource‐constrained edge computing. Here, a bias‐dependent photodiode (BD‐PD) with a semi‐gate interconnecting drain based on a 2D MoS2/CIPS heterojunction is proposed, exhibiting the ability to autonomously manage photo‐electrical characteristics without any additional gate voltage. Density functional theory validates that the formation of a type‐I band alignment in MoS2 channel is bias‐dependent due to the bias synchronizing the semi‐gate, inducing an anomalous bias‐depended current that the dark current is reduced while photocurrent is increased as the bias increases. The high photodetection performances are exhibited including an ultra‐high photo‐to‐dark current ratio over 106, a detectivity of 8×1014 Jones, and a responsivity of 3454 A W−1 at a bias of 3 V, respectively. Moreover, it is demonstrated that the bias‐dependence of the BD‐PD can obviously improve image preprocessing and optical communication. This work provides a promising platform for the application of neuromorphic optoelectronics.

AbstractThe composite solid‐state electrolyte, composed of polyvinylidene fluoride (PVDF) polymer and garnet, exhibits great promising in solid‐state batteries. However, the dehydrofluorination of PVDF induced by the garnet narrows its voltage window and deteriorates the electrode‐electrolyte interface, inhibits ion transport. Here, a coordination interphase is constructed on garnet fillers via in situ polymerization of cyanoethyl cellulose (CEC) to stabilize the organic/inorganic interface. La atoms in garnet coordinating with C≡N groups of CEC, creating a Lewis basic environment that facilitates the linking of adjacent C≡N groups to form conjugated C═N sequences, thereby forming a 5‐nm ultrathin polycyanethyl cellulose (PCEC) layer on the garnet surface. The interaction between PCEC and garnet triggers the strong Li+ ion adsorption, thus producing a fast Li+ ion migration pathway through the garnet/PCEC interface. Consequently, the composite electrolyte demonstrates a high room‐temperature ionic conductivity of 5.6 × 10−4 S cm−1, a high cutoff voltage of up to 4.8 V versus Li+/Li, and excellent stability against lithium metal. Using this electrolyte, a practical 560 mAh Li|LiNi0.9Co0.05Mn0.05O2 solid‐state lithium metal pouch cell achieves superior weight and volume energy densities of up to 408 Wh kg−1 and 733 Wh L−1, respectively.

AbstractWith the rapid advancement of 2D material‐based optoelectronic devices, significant progress is made in the development of all‐optical logic devices, synaptic biomimetic devices, and multidimensional detection systems. As entering to the high‐speed information era, there is an urgent demand for complex, compact, multifunctional, low‐energy, and high‐speed intelligent sensing chips. Examining the evolution of current technologies reveals a parallel in the advancement of bipolar response mechanisms‐from simple positive and negative responses to more intricate inhibition‐promotion dynamics with persistent characteristics. This evolution significantly broadens their applications in biomimetic devices. Moreover, compared to unipolar responses, complex bipolar responses offer greater flexibility in adaptation and a unique one‐to‐one mapping with high‐dimensional information parameters such as polarization, phase, and spectrum, positioning them as promising candidates for breakthroughs in multidimensional detection and resolution. In this review, design strategies are comprehensively explored for various bipolar responses in 2D materials, highlighting their deep applications and progress in advanced fields. It is aimed for this review to provide a broad overview of bi‐directional response mechanisms, offering inspiration for designing the next generation of intelligent sensing chips.

AbstractRegulating metal‐support interactions enables rational design of catalysts with enhanced performance in Fenton‐like oxidation reactions. Here, a novel oxygen‐doped, stalactite‐like g‐C3N4 supported FeOCl (FeOCl‐OCN) is successfully synthesized. Due to the modulation of O doping to the work function (Φ) of g‐C3N4 support, a delicate built‐in electric field (BIEF) oriented from OCN to FeOCl is constructed. Driven by large work function difference (ΔΦ = 3.235 eV), the interfacial charge transfer manipulates electron redistribution to achieve a rearrangement of structural Fe(II)/Fe(III). Based on theoretical calculations and mechanism insight, the interaction between FeOCl and OCN exhibits a stronger binding ability to peroxymonosulfate (PMS) and reduces the energy barriers for *O formation, therefore favoring a higher yield of singlet oxygen (1O2) and high‐valent iron‐oxo (Fe(IV)═O)− species. As a result, the FeOCl‐OCN/PMS system demonstrates a nonradical‐dominated pathway, delivering high activity (k
obs = 0.250 min−1), robust tolerance to pH variation and resistance, and excellent stability.

AbstractAlloy electrodes, beneficial from excellent stability, are considered suitable for industrial applications, hence exploring alloy catalysts with low reaction barriers will bring innovative scientific understanding and enormous economic benefits. Recently, material informatics emerges as an efficient method in the research and development of new materials through diverse candidates, however, collecting a large amount of material characterization and simulation data still faces numerous difficulties. To tackle this issue, combining the topological structure of materials, the convolutional neural network framework developed in this article first achieves the density of states prediction of active sites on the alloy surface, based on which the adsorption energy of different reactants is obtained. Benefited by electronic structure, this model exhibits excellent predictive performance with a mean absolute error of 0.124 eV, and transferability with fast convergence under dozens transferred data to complete the extension for high entropy alloys and reactants. Based on this massive predictive data, high entropy alloy catalysts with excellent low reaction barrier have been discovered, and several catalytic theories, like scaling relations, d‐band center theory, high‐entropy effects and synergistic catalysis, have been validated and improved.

AbstractUnsatisfying preparation controllability, mechanical properties, ionic conductivities, and working voltage windows limit the practical applications of solid polymer electrolytes (SPEs) in lithium‐metal batteries. Herein, a 3D printing strategy combined with zwitter molecule modification is proposed to efficiently solve the problems of SPEs with a polyvinylidene fluoride‐hexafluoropropylene (PH) matrix. The electron‐donating property resulting from the carboxyl groups of aspartate acid (Asp) induces the cis‐conformation change of polyvinylidene fluoride, which enhances the Li+ transport and anion immobilization on polymer chains. In addition, the amphoteric functional groups of Asp simultaneously promote the lithium salt dissociation and Li+ desolvation with N,N‐dimethylformamide, thus leading to the formation of stable Li3N/LiF‐enriched interphases between electrodes and electrolyte. Moreover, the 3D printing technology increases the continuity and uniformity of the SPE membrane, further increasing the ionic conductivity and mechanical properties. As a result, the SPE exhibits high ionic conductivity (1.20 × 10−4 S cm−1), large transfer number (0.68), wide electrochemical window (4.6 V), and good tensile strength (≈110 MPa), endowing the half cells with good cycling performance over 2000 h with a low overpotential of 40 mV. Furthermore, high‐energy densities (492 Wh kg−1 and 1303 Wh L−1) are delivered by a pouch cell with the SPE, indicating good application prospects.
