AbstractFlexible and wearable sensors show enormous potential for personalized healthcare devices by real‐time monitoring of an individual's health. Typically, a single functional material is selected for one sensor to sense a particular physical signal while multiple materials will be selected for multi‐mode sensing. Vertically aligned nanocomposites (VANs) have recently demonstrated various material combinations and novel coupled multifunctionalities that are hard to achieve in any single‐phase material alone, including multiphase multiferroics, magneto‐optic coupling, and strong magnetic and optical anisotropy. Integrating these novel VANs into wearable sensors shows enormous potential in multi‐mode sensing owing to their multifunctional nature. In this work, the transfer of VANs onto polydimethylsiloxane as a novel flexible chemical and pressure sensor is demonstrated. For this demonstration, the classical BaTiO3 ‐Au VAN with combined plasmonic and piezoelectric properties is used to demonstrate a multi‐sensing mechanism. A thin water‐soluble buffer of Sr3Al2O6 serves as a buffer layer for the epitaxial growth and transfer process. The electrical output based on the piezoelectric responses and identifying 4‐mercaptobenzoic acid by surface‐enhanced Raman spectroscopy reveal great potential for free‐standing VANs in a wearable multifunctional sensing platform.

AbstractCatalytic seawater electrolysis is a valuable renewable energy generation process. However, it is restricted by the intricate and corrosive ionic nature of seawater which hinders oxygen evolution reaction (OER), one of the reactions governing seawater electrolysis. Herein, we introduce an effective approach that not only withstands, but also harnesses the potential of complex ions in seawater to enhance the efficiency and durability of OER. Unlike conventional strategies that address adverse effects through catalyst surface modification, we found that seawater actively facilitates the reconstruction of catalysts with high‐spin sites. In situ characterizations suggest that the selective adsorption of Cl− from seawater on high‐spin Co sites in alkaline seawater accelerates catalyst reconstruction, contributing to the rapid formation of high‐valence Co, which enhances OER activity. The resulting reconstructed wrinkled nanosheets also create additional active Co sites and accelerate electrolyte transport. As a result, we achieve an overpotential as low as 377 mV at a current density of 1 A cm−2, showcasing nearly 100% oxygen evolution efficiency in alkaline seawater. Notably, our approach achieves a remarkable current density of 2.13 A cm−2 prior to the onset of the chlorine evolution reaction, underscoring its potential for efficient and sustainable seawater electrocatalysis.

AbstractCurrent biodegradable materials are facing many challenges when used for the design of implantable devices because of shortcomings such as toxicity of crosslinking agents and degradation derivatives, limited cell adhesion, and limited immunological compatibility. Here, a class of materials built entirely of stable protein is designed using a simple protocol based on salt‐assisted compaction of albumin, breaking with current crosslinking strategies. Salt‐assisted compaction is based on the assembly of albumin in the presence of high concentrations of specific salts such as sodium bromide. This process leads, surprisingly, to water‐insoluble handable materials with high preservation of their native protein structures and Young's modulus close to that of cartilage (0.86 MPa). Furthermore, these materials are non‐cytotoxic, non‐inflammatory, and in vivo implantations (using models of mice and rabbits) demonstrate a very slow degradation rate of the material with excellent biocompatibility and absence of systemic inflammation and implant failure. Therefore, these materials constitute promising candidates for the design of biodegradable scaffolds and drug delivery systems as an alternative to conventional synthetic degradable polyester materials.

AbstractRenal ischemia/reperfusion injury (IRI) is a common form of acute kidney injury. The basic mechanism underlying renal IRI is acute inflammation, where oxidative stress plays an important role. Although bilirubin exhibits potent reactive oxygen species (ROS)‐scavenging properties, its clinical application is hindered by problems associated with solubility, stability, and toxicity. In this study, BX‐001N, a synthetic polyethylene glycol‐conjugated bilirubin 3α nanoparticle is developed and assessed its renoprotective effects in renal IRI. Intravenous administration of BX‐001N led to increase uptake in the kidneys with minimal migration to the brain after IRI. Peri‐IRI BX‐001N administration improves renal function and attenuates renal tissue injury and tubular apoptosis to a greater extent than free bilirubin on day 1 after IRI. BX‐001N suppressed renal infiltration of inflammatory cells and reduced expression of TNF‐α and MCP‐1. Furthermore, BX‐001N increases renal tubular regeneration on day 3 and suppresses renal fibrosis on day 28. BX‐001N decreases the renal expressions of dihydroethidium, malondialdehyde, and nitrotyrosine after IRI. In conclusion, BX‐001N, the first Good Manufacturing Practice‐grade synthetic bilirubin‐based nanomedicine attenuates acute renal injury and chronic fibrosis by suppressing ROS generation and inflammation after IRI. It shows adequate safety profiles and holds promise as a new therapy for renal IRI.

AbstractMutual acquisition of phase‐stability and controllable phase‐transition becomes a predominant criterion of phase‐change materials for the practical long‐term energy storage but seems contradictory always. Here a strategy combining coordination and hydrogen bonds hierarchically to create a supercooled liquid in a core–shell coordination structure is reported, addressing that demand successfully. This new material is composed of a Mn‐methylurea complex (MM) core and the hierarchically bonded erythritols shell. MM glass core with a viscosity of 108 Pa·s determines its thermal phase‐stability. As discovered, the ingenious ligand‐exchange between erythritol and Cl− ion coordinated with MM core accounts for this effectively reversible phase‐transition. This can be triggered by a small shear‐stress of 10 Pa within tens of seconds, exhibiting good practicability. Thermodynamics and kinetics of phase‐transition are explored.

AbstractThe epitaxial growth of molybdenum disulfide (MoS₂) on sapphire substrates enables the formation of single‐crystalline monolayer MoS₂ with exceptional material properties on a wafer scale. Despite this achievement, the underlying growth mechanisms remain a subject of debate. The epitaxial interface is critical for understanding these mechanisms, yet its exact atomic configuration has previously been unclear. In this study, a monolayer single‐crystalline MoS₂ grown on a sapphire substrate is analyzed, decisively visualizing the atomic structure of the epitaxial interface and elucidating its role in epitaxial growth from an atomic perspective. The findings reveal that the interface consists of a periodic molecular MoO3 interlayer, van der Waals epitaxially grown on a single Al‐terminated sapphire surface. Additionally, it is discovered that MoO3 coverage enhances surface interactions and introduces a unique atomic arrangement with 1‐fold symmetry at the sapphire surface, thereby facilitating the unidirectional alignment of MoS₂. This discovery provides valuable insights into the growth mechanisms leading to single‐crystalline MoS₂ formation, and suggests pathways for quantitatively monitoring and controlling growth dynamics, for the improvement of material quality and process repeatability, applicable for single‐crystalline MoS₂ or potentially other transition metal dichalcogenides epitaxially grown on sapphire.

AbstractComputed tomography (CT) imaging has emerge as an effective medical diagnostic technique due to its rapid and 3D imaging capabilities, often employing indirect imaging methods through scintillator materials. Arraying scintillators that can confine light scattering to enable high‐resolution CT imaging remains an area of ongoing exploration for emerging perovskite scintillators. Here an anti‐scattering cesium lead bromide (CsPbBr3) scintillator array embedded within a polyurethane acrylate matrix for CT imaging using a cost‐effective solution‐processed method is reported. Due to the large refractive index contrast between the scintillator and matrix, photon propagation can be well confined within the CsPbBr3 scintillator array to significantly suppress the light scattering and enhance the light collection efficiency by nearly two times compared to the monolithic film. Furthermore, the scintillator array exhibits low‐dosage and high‐resolution CT imaging capability by reconstructing a 3D tooth image with a good spatial resolution of 20.1 lp cm−1 at a low effective dose of 0.22 mSv. This work highlights that the CsPbBr3 scintillator array is a highly promising candidate for CT imaging.

AbstractElectrocatalytic biomass conversion offers a sustainable route for producing organic chemicals, with electrode design being critical to determining reaction rate and selectivity. Herein, a prediction‐synthesis‐validation approach is developed to obtain electrodes for precise biomass conversion, where the coexistence of multiple metal valence states leads to excellent electrocatalytic performance due to the activated redox cycle. This promising integrated foam electrode is developed via acid‐induced surface reconstruction to in situ generate highly active metal (oxy)hydroxide or oxide (MOxHy or MOx) species on inert foam electrodes, facilitating the electrooxidation of 5‐hydroxymethylfurfural (5‐HMF) to 2,5‐furandicarboxylic acid (FDCA). Taking nickel foam electrode as an example, the resulting NiOxHy/Ni catalyst, featuring the coexistence of multivalent states of Ni, exhibits remarkable activity and stability with a FDCA yields over 95% and a Faradaic efficiency of 99%. In situ Raman spectroscopy and theoretical analysis reveal an Ni(OH)2/NiOOH‐mediated indirect pathway, with the chemical oxidation of 5‐HMF as the rate‐limiting step. Furthermore, this in situ surface reconstruction approach can be extended to various metal foams (Fe, Cu, FeNi, and NiMo), offering a mild, scalable, and cost‐effective method for preparing potent foam catalysts. This approach promotes a circular economy by enabling more efficient biomass conversion processes, providing a versatile and impactful tool in the field of sustainable catalysis.

AbstractAmong the spectral features of photovoltaic materials, the large molar extinction coefficients and low band‐tailing absorption ensure efficient photon utilization and reduced energy loss. Non‐fullerene acceptors (NFAs), such as ITIC and Y6, significantly propel photovoltaic performance due to their strong absorption and steep band edges. The frontier orbitals of ITIC and Y6 mainly distribute on central conjugated backbones while little on electron donor and terminal acceptor segments, indicating a more localized electronic signature rather than a charge transfer state. The single crystal structures of ITIC and Y6 indicate that the π‐conjugated backbones appear homogeneous carbon‐carbon bond lengths, and the calculated atomic charge distribution demonstrates that the carbon atoms of π‐conjugated backbones carry alternating positive and negative partial charges, revealing soliton‐like electronic structural characteristics in these molecules. Inspired by cyanine dyes, these soliton‐like features are considered to be the origin of ITIC and Y6 strong and tailless absorption spectra. Further analysis shows that the introduction of an acceptor group (benzothiadiazole) induces more extensive soliton waves in the conjugated backbones (Y6) compared to ITIC, resulting in stronger absorption and steeper band edge. The analysis suggests that soliton‐type NFA materials are expected to provide new insight for designing high‐performance organic photovoltaic materials.

AbstractHalide perovskite solar cells are approaching commercialization, with solution processing emerging as a key method for large‐scale production. This study introduces a significant advancement: using non‐toxic solvents like water and alcohol in perovskite precursor inks facilitated by the protic ionic liquid methylammonium propionate (MAP). MAP effectively dissolves perovskite precursors such as lead acetate and methylammonium iodide, enabling the first stable water‐based perovskite precursor ink suitable for one‐step slot‐die coating. This new ink formulation contrasts with conventional dimethylformamide (DMF) and dimethylsulfoxide (DMSO)‐based inks, as evidenced by in‐situ grazing incidence wide‐angle X‐ray scattering (GIWAXS), which revealed an intermediate‐free liquid‐to‐solid transition. In‐situ mass spectrometry also showed that organic molecules evaporate during annealing, resulting in a crystalline perovskite phase. Optimization of the solvent mixture to H2O/IPA/MAP enabled successful slot‐die coating, yielding perovskite solar cells with an efficiency of up to 10%. This eco‐friendly ink reduces toxicity and environmental impact compared to DMF‐based inks, offering a longer shelf life and the possibility of using the ink in ambient conditions. This pioneering work represents the first report of a water‐based green ink formulation for one‐step thin film coating at room‐temperature conditions by slot‐die coating, highlighting its potential for sustainable commercial applications.

AbstractPhotoreforming waste plastics into valuable products is a promising approach, but it requires efficient, eco‐friendly photocatalysts and a deeper understanding of catalytic mechanism. We have developed a B‐doped g‐C3N4 nanotube catalyst with well‐defined structure for photoreforming poly(ethylene terephthalate) (PET) into valuable chemicals and H2. This catalyst achieved a H2 evolution rate of 3240 μmol gcatal−1 h−1, outperforming previous cadmium‐free catalysts. It also oxidized PET to higher‐value organic acids via a hole oxidation mechanism. Experimental and theoretical calculations showed that B atom doping not only greatly increased the catalyst's active sites, but also significantly accelerated the electron–hole separation and transfer rate, optimized the adsorption and activation behavior of the substrate. Using concentrated sunlight, we achieved a H2 evolution rate of 475 μmol gcatal−1 h−1 for real‐world PET in seawater. Techno‐economic analysis suggests processing 50,000 tons of waste plastic annually could yield a profit of $7.45 million.

AbstractPrecisely manipulating asymmetric coordination configurations and examining electronic effects enable to tunethe intrinsic oxygen reduction reaction (ORR) activity of single‐atom catalysts (SACs). However, the lackof a definite relationship between coordination asymmetry and catalytic activity makes the rational design of SACs ambiguous. Here, we propose a concept of “asymmetry degree” to quantify asymmetric coordination configurations and assess the effectiveness of active moieties in Fe‐based SACs. A theoretical framework is established, elucidating the volcanic relationship between asymmetry degree and ORR activity by constructing a series of Fe‐based SAC models doped with non‐metal atoms (B, P, S, Se, and Te) in the first or second coordination sphere, which aligns with Sabatier principle. The predicted ORR activity of Fe asymmetric active moieties is then experimentally validated using asymmetry degree. The combined computational and experimental results suggest that single‐atom moiety with a moderate asymmetry degree exhibits optimal intrinsic ORR activity, because breaking the square‐planar symmetry of FeN4 can alter the electronic population of the Fe 3d‐orbital, thereby optimizing the adsorption‐desorption strength of intermediates and thus enhancing the intrinsic ORR activity. This fundamental understanding of catalytic activity from geometric and electronic aspects offers a rational guidance to design high‐performance SACs with asymmetric configurations.

ABSTRACTThe therapeutic potential of plant‐derived proanthocyanidins (PACs) interacting with mammalian collagen is extensive, notably in strengthening specialized extracellular matrix like the dentin matrix, crucial for reparative dental treatments. This study unveils an additional facet of PACs beyond their recognized chemical and biomechanical advantages in fibrillar collagen: specific tannins possess an inherent capability to influence collagen mineralization. By leveraging the degree of polymerization (DP) of PAC oligomers binding directly to type‐I collagen, selective control over in vitro mineralization is achieved. Tetrameric PACs (DP = 4) exhibit minimal barriers to extrafibrillar mineralization, whereas dimers (DP = 2) effectively hinder nucleation/growth of surface minerals, potentially favoring intrafibrillar mineralization pathways. Additionally, our investigation highlights that bound PACs facilitate the infiltration of mineral precursors within collagen fibrils without relying on conventional process‐directing agents. These findings underscore the promising utility of oligomeric PACs as a new class of plant‐derived process‐directing agents (PPDAs) with compelling mineral activities. While our primary focus is exploring mineralization through diverse PAC structures, establishing a translatable collagen mineralization model remains one long‐term goal of this line of research.

ABSTRACTCoolant, a general term for all chemical substances that produce a cooling effect without strong medicinal properties. Currently reported coolants are generally used as additives directly in food and daily chemicals. Here we pioneered a responsive nanoscale formulation to improve the application limitations of coolants. The cooling agent consists of 1,3‐propanediol, high‐substituted hydroxypropyl cellulose(H‐HPC), and three coolants, utilizing H‐HPC as the polymer shell that encapsulates and releases the coolants. It has long‐lasting release properties and can be released immediately upon contact with water through the vesicle structure formed by H‐HPC. The cooling agent has a particle size between 20 and 60 nm, a pH between 6.16 and 7.28, a refractive index between 1.400 and 1.500, a viscosity between 1500 and 3000 mPa s, and a good stability without precipitation and delamination after centrifugation. Meanwhile, the cold stimulation neuron test shows the excellent performance of longer duration and better effect than menthol cooling sensation. Its good formulation application shows a better application prospect in cosmetics and light chemical industry.
