Abstract2D transition metal dichalcogenide (TMD) gradient alloys hold great promise for electronic and optoelectronic applications, benefiting from their structural and compositional diversity as well as potential multifunctionalities. However, critical challenges remain in the controlled synthesis and unexplored uses of 2D TMD gradient alloys compared to single‐composition 2D TMDs. Herein, a “Face‐to‐Face” general synthesis strategy, which enables large‐area, uniform, and highly reproducible preparation of multiple types of 2D TMD gradient alloys in a single configuration through precise control on precursor supply, and the spatial confinement effect is reported. The synthesized single‐layer Mo1‐xWxS2 gradient alloy features a graded energy band and an alloyed region with moderate intrinsic sulfur vacancies, which is beneficial to achieving the high photo‐synaptic response. Optoelectronic synaptic devices utilizing the unique properties of 2D gradient alloys demonstrate various neuromorphic behaviors, such as outstanding‐index 161% paired‐pulse facilitation, stimuli‐dependent transition from short‐term plasticity to long‐term plasticity, emulation of the brain‐like learning processes, and simulation of neuromorphic vision on artificial neural network for handwritten digit recognition with over 95.6% accuracy. The present general synthesis method of 2D gradient alloys and their great potential as high‐performance optoelectronic synapses may open new frontiers for the 2D TMD family.

AbstractHyperglycemia exacerbates bacterial infections, disrupts angiogenesis, and perpetuates chronic inflammation in the wound. Therefore, the effective management of diabetic wounds necessitates a synergistic approach that integrates local wound microenvironment remodeling with systemic hyperglycemia regulation. Herein, an unprecedented hierarchical cobalt pyrophosphate/DNA (Co2PPi/DNA) nanocomposite is reported for this purpose. Unlike the stereotypical assembly of either enzymatically polymerized ultralong nucleic acids with Mg2PPi nanosheets at low assembly ratios or commercial homo‐oligonucleotides devoid of biofunctionalities in the presence of metal ions, this study represents the first demonstration on coordination‐driven high‐efficiency co‐assembly of biofunctional hetero‐oligonucleotides and non‐Mg2PPi nanosheets, specifically glucagon receptor (GCGR) aptamer and Co2PPi nanosheets. To improve the bioavailability of nanocomposites, a dissolvable microneedle patch is applied for their wound delivery. Thereafter, nanocomposites dissociate in the wound for sustained release of Co2+ ions and GCGR aptamer, from which Co2+ ions eliminate colonized bacteria and promote angiogenesis through stabilizing HIF‐1α, meanwhile, aptamer after circulating to liver reduces blood glucose levels by binding to hepatocyte GCGR. Importantly, this hypoglycemic effect promotes antibacterial and pro‐angiogenic efficacy and alleviates the inflammatory responses. This work highlights significant advancements in the coordination of biofunctional hetero‐oligonucleotides into a versatile nanocomposite architecture to remodel local pathological microenvironment facilitated by systemic factor regulation.

AbstractHeteroatom‐bridged dual‐atom catalysts (DACs), featuring more flexible active sites and intermetallic interaction, provide an opportunity for sustainable environmental remediation. Herein, an innovative oxygen‐bridged Co‐Cu DAC supported on nano‐alumina (CoOCu‐DAC) is fabricated using a straightforward two‐step process. The as‐prepared catalyst significantly enhances both decontamination kinetics and peroxymonosulfate (PMS) utilization efficiency by 1–3 orders of magnitude toward monoethanolamine (MEA, pKa = 9.5) compared to Co single‐atom catalyst (Co‐SAC) and bulk metal catalysts, and largely outperforms previously reported systems. In‐situ ATR‐FTIR and theoretical investigations reveal that the secondary introduction of Cu plays multiple important roles: it activates lattice oxygen to trigger key proton transfer (PT) of MEAH+ via nucleophilic attack at the interface and subsequently favors deprotonated MEA as an efficient electron donor to accelerate electron transfer (ET) by enhancing orbital overlaps for the co‐activation of O2 and PMS. Such a stepwise proton‐coupled electron transfer (PCET)‐enhanced catalytic pathway mediated by CoOCu‐DAC is fundamentally different from common route identified in Co‐SAC‐involved Fenton‐like system. The established binary QSAR further substantiates the universality of PCET‐enhanced strategy toward versatile nitrogen‐containing organic compounds. This study offers a new perspective for sustainable water decontamination and other related areas of catalysis based on rationalized design of multifunctional catalysts at atomic level.

AbstractCurrent challenges in tissue engineering include creation of extracellular environments that support and interact with cells using biochemical, mechanical, and structural cues. Spatial control over these cues is currently limited due to a lack of suitable fabrication techniques. This study introduces Xolography, an emerging dual‐color light‐sheet volumetric printing technology, to achieve control over structural and mechanical features for hydrogel‐based photoresins at micro‐ to macroscale while printing within minutes. A water‐soluble photoswitch photoinitiator system and a library of naturally‐derived, synthetic, and thermoresponsive hydrogels for Xolography are proposed. Centimeter‐scale, 3D constructs with positive features of 20 µm and negative features of ≈100 µm are fabricated with control over mechanical properties (compressive moduli 0.2 kPa–6.5 MPa). Notably, switching from binary to grayscaled light projection enables spatial control over stiffness (0.2–16 kPa). As a proof of concept, grayscaled Xolography is leveraged with thermoresponsive hydrogels to introduce reversible anisotropic shape changes beyond isometric shrinkage. Xolography of viable cell aggregates is finally demonstrated, laying the foundation for cell‐laden printing of dynamic, cell‐instructive environments with tunable structural and mechanical cues in a fast one‐step process. Overall, these innovations unlock unique possibilities of Xolography across multiple biomedical applications.

AbstractEfficient magnetization control is a central issue in magnetism and spintronics. Particularly, there are increasing demands for manipulation of magnetic states in van der Waals (vdW) magnets with unconventional functionalities. However, the electrically induced phase transition between ferromagnetic‐to‐antiferromagnetic states without external magnetic field is yet to be demonstrated. Here, the current‐induced magnetic phase transition in a vdW ferromagnet Fe5GeTe2 is reported. Based on magneto‐transport measurements and theoretical analysis, it is demonstrated that transition in the interlayer magnetic coupling occurs through vertical voltage drop between layers induced by current which is attributed to high anisotropy of the resistivity caused by the vdW gaps. Such magnetic phase transition results in giant modulation of the longitudinal magnetoresistance from 5% to 170%. The electrical tunability of the magnetic phase in Fe5GeTe2 with current‐in‐plane geometry opens a path for electric control of magnetic properties, expanding the ability to use vdW magnets for spintronic applications.

AbstractGem‐difluoroethylene moiety holds pivotal roles in drug research owing to its unique ability as a bioisostere of the carbonyl group. Here, magnesium‐mediated reductive defluorinative cross‐electrophile coupling of α‐trifluoromethyl styrene with carbon‐centered electrophiles was developed. This method featured readily accessible reagents, mild conditions, and wide substrate scope, enabling the efficient production of gem‐difluoroallyl carboxylic acid and ketones. The establishment of this protocol will offer a general alternative for the acquisition of gem‐difluoroethylene compounds.

AbstractAspartate (Asp) metabolism‐mediated antioxidant functions have important implications for neonatal growth and intestinal health; however, the antioxidant mechanisms through which Asp regulates the gut microbiota and influences RIP activation remain elusive. This study reports that chronic oxidative stress disrupts gut microbiota and metabolite balance and that such imbalance is intricately tied to the perturbation of Asp metabolism. Under normal conditions, in vivo and in vitro studies reveal that exogenous Asp improves intestinal health by regulating epithelial cell proliferation, nutrient uptake, and apoptosis. During oxidative stress, Asp reduces Megasphaera abundance while increasing Ruminococcaceae. This reversal effect depends on the enhanced production of the antioxidant eicosapentaenoic acid mediated through Asp metabolism and microbiota. Mechanistically, the application of exogenous Asp orchestrates the antioxidant responses in enterocytes via the modulation of the RIP3‐MLKL and RIP1‐Nrf2‐NF‐κB pathways to eliminate excessive reactive oxygen species and maintain mitochondrial functionality and cellular survival. These results demonstrate that Asp signaling alleviates oxidative stress by dynamically modulating the gut microbiota and RIP‐dependent mitochondrial function, providing a potential therapeutic strategy for oxidative stress disease treatment.

Published: January 2025

AbstractAccurate, non‐invasive, and wearable measurement of arterial pressure pulse waveforms is crucial for cardiovascular healthcare, yet remains challenging due to the lack of effective sensors and mounting methods. This study introduces highly sensitive, flexible PZT piezoelectric sensors and an optimized mounting method for accurate radial pulse waveform measurement in natural wrist positions. The sensors incorporate a PZT thin film directly fabricated on a flexible substrate with easily produced parallel‐plate electrodes, requiring no poling treatment. The high‐quality PZT films exhibit low charge leakage, enabling measurement even at 1 Hz. To ensure comfort and accuracy, a foam pad is used for optimal sensor mounting and investigate how its stress–strain properties affect pulse detection. The optimized sensor device captures waveforms closely matching those from a high‐accuracy capacitive force sensor. Despite smaller size and lower mounting load, the sensors show four times the sensitivity of polyvinylidene fluoride sensors and successfully detect age‐related changes in waveforms. Additionally, a deep learning model is developed to enable calibration‐free conversion of sensor signals to blood pressure (BP), achieving a mean absolute error of 5.82 and 4.60 mmHg for systolic and diastolic BP. These results highlight the potential of this technology for effective cardiovascular monitoring in daily life.

AbstractThe slow reaction kinetics of hydrogen oxidation reaction (HOR) on existing catalysts in alkaline hinders the commercialization of anion exchange membrane fuel cells (AEMFCs). In this work, a Cu‐incorporated NiW alloy (Cui‐NiW) without any platinum group metal (PGM) is designed and evaluated in both liquid cells and AEMFCs. This catalyst enabled the achievement of an electrochemical surface area‐normalized exchange current density of 70 µA cm−2 and robust stability, outperforming most PGM‐free catalysts. Furthermore, the incorporation of Cu into other systems such as NiMo and NiV using the same method also showcased excellent HOR activity and durability. The fuel cells assembled with Cui‐NiW as the anode and Pt/C or Fe‐N‐C as the cathode delivered peak power densities of 480 and 340 mW cm−2, respectively. Experimental and theoretical studies reveal that the incorporated Cu is chemically inert but enhances the overall oxidation resistance of the catalysts. Moreover, it weakens hydrogen adsorption and promotes the adsorption of hydroxide ions, thereby enhancing the HOR activity significantly. These results may open a door for rational design of high‐performance and durable PGM‐free HOR catalysts.
Oscillating microbubbly flows generated by a fluidic oscillator: Flow behavior and mass transfer characteristics
Authors: Zheng Longyun , Qi Ao , Guo Kai , Liu Chunjiang , Wen Xin 
Published: January 2025

AbstractIn this study, a Coanda‐swept fluidic oscillator is used to generate oscillating microbubbly flows. Flow behavior measurements show that the generated microbubbly flows have periodic sweep characteristics. Massive microbubbles are generated by shear‐off‐induced breakup, dynamic erosion breakup, and wall‐fluid‐shear‐induced breakup within the fluidic oscillator. Mass transfer measurements show that the generated microbubbly flows have a higher interfacial area (a) and volumetric liquid‐side mass transfer coefficients (kL) than the other comparison groups. Furthermore, the energy efficiency is assessed in terms of kL per energy consumption (η) and energy consumption per a (ξ). For the fluidic oscillator group, the highest kLa is 0.089 s−1, corresponding to (η = 0.63 m3/(kW·s), ξ = 2.6 J/m2, a = 785 m2/m3). Although it has been reported that higher kLa is typically associated with lower energy efficiency, the results indicate that the fluidic oscillator is a promising microbubble generator.

Published: January 2025

AbstractIn this study, an innovative strategy is proposed to design porous ionic liquids (PILs) using lipophilicity differences, defined as type III‐B PIL, which overcomes the traditional size‐effect limitations in PIL design. An SBA‐15 confined high‐entropy single‐atom catalyst (HESAC@SBA‐15) with an oleophobic internal surface was engineered as the porous framework and oleaginous 1‐butyl‐3‐methylimidazolium tetrafluoroborate as the organic guest for constructing a novel type PIL (PILS‐B). This type of PILS‐B combines the exceptional gas storage capacity of PILs with the high catalytic activity of HESAC@SBA‐15. Additionally, the mesoporous structure of SBA‐15 enhances mass transfer during reactions, thereby improving catalytic efficiency. Using the aerobic oxidation of aromatic sulfur compounds in fuel oils as a model reaction, PILS‐B achieved a desulfurization efficiency of >99%. This strategy expands the variety of porous frameworks and organic guests for PIL design, showcasing the potential of PILs as effective and stable catalysts with broader applications in catalysis.

Published: January 2025

ABSTRACTThis paper explores the experiences of young people in Queensland, Australia, under child protection orders who leave approved out‐of‐home care placements (e.g., foster; residential care) to stay in unapproved locations (e.g., sleeping on the streets; staying with friends, family/kin, or strangers). This phenomenon is commonly referred to as ‘self‐placing’. Young people who self‐place are at increased risk of homelessness, exploitation, contact with the justice system, and disconnection from support services, including education and health care. We argue that this disconnection from formal support impedes their access to transition care planning and support—factors internationally recognised as essential for enhancing outcomes for care leavers. Our paper draws on qualitative interviews with 11 young people with experience of self‐placing and focus group data involving 26 statutory child protection practitioners and 17 specialist non‐government practitioners. We describe the ways in which self‐placing was perceived to shape young people's access to, and practitioners' ability to provide, transition planning and support. We identify ongoing gaps and examples of good practice to inform more robust transition from care policies that are responsive to the needs of this marginalised cohort.
Homelessness and Housing Instability Among Care Leavers in Australia: Exploring Housing Pathways and Best Practice Housing Models
Authors: Zhao Yujie , Waugh Jacinta 
Published: January 2025

ABSTRACTA significant proportion of young people exiting Out‐of‐Home Care (OOHC) encounter substantial challenges in securing housing, often leading to homelessness within a few months after leaving care. All Australian jurisdictions have now approved extended care programs up to 21 years; however, none of them currently offer these young people guaranteed accommodation options. This study aims to explore the factors underlying poor housing outcomes among care leavers and to develop a best practice model that complements the extended care framework in Australia, thereby addressing or ameliorating homelessness issues among these young adults. A scoping review of 18 scholarly articles and seven grey literature reports supplemented by ancestral search forms the basis of a thematic analysis. This analysis reveals factors contributing to negative and positive housing outcomes for young people related to OOHC transitional processes in Australia and Organisation for Economic Co‐operation and Development (OECD) nations. It includes evaluations of the implementation of extended care and of housing programs in these countries. By analysing current extended care policies in each jurisdiction, as well as literature featuring good post‐care housing practices both locally and internationally, five key principles have been identified for a best practice model.
