AbstractChromium oxychloride (CrOCl), a van der Waals antiferromagnetic insulator, has attracted significant interest in 2D optoelectronic, ferromagnetic, and quantum devices. However, the bottom–up preparation of 2D CrOCl remains challenging, limiting its property exploration and device application. Herein, the controllable synthesis of 2D CrOCl crystals by chemical vapor deposition is demonstrated. The combination reaction of precursors together with the space‐confined growth strategy, providing stable and stoichiometric growth conditions, enable a robust synthesis of high‐crystallinity CrOCl nanosheets with regular rhombus‐like morphology and uniform thickness. By tuning the growth temperature from 675 to 800 °C, the thickness of CrOCl nanosheets can be continuously modulated from 10.2 to 30.8 nm, with the domain size increasing from 16.9 to 25.5 µm. The as‐grown CrOCl nanosheets exhibit significant structural/optical anisotropy, ultrahigh insulativity, and superior air stability. Furthermore, a MoS2/CrOCl heterostructure with single‐mirror symmetry stacking and ultrastrong interfacial coupling is built to realize interfacial symmetry breaking, a novel interface phenomenon that converts MoS2 from isotropy to anisotropy. Consequently, the MoS2/CrOCl heterostructure device achieves polarization‐sensitive photodetection and bulk photovoltaic effect, which are nonexistent in high‐symmetry 2D materials. This work paves the way for the future exploration of CrOCl‐based 2D physics and devices via symmetry engineering.

AbstractThe significant contact resistance at the metal‐semiconductor interface is a well‐documented issue for organic thin‐film transistors (OTFTs) that hinders device and circuit performance. Here, this issue is tackled by developing three new thiol carbazole‐based self‐assembled monolayer (SAM) molecules, namely tBu‐2SCz, 2SCz, and Br‐2SCz, and utilizing them as carrier‐selective injection interlayers. The SAMs alter the work function of gold electrodes by more than 1 eV, making them suitable for use in hole and electron‐transporting OTFTs. Scanning tunneling microscopy analysis indicates that 2SCz and Br‐2SCz form highly ordered molecular rows, resulting in work function values of 4.86 and 5.48 eV, respectively. The latter value is higher than gold electrodes modified by the commonly used pentafluorobenzenethiol (≈5.33 eV), making Br‐2SCz promising for hole injection. Conversely, tBu‐2SCz appears disordered with a lower work function of 4.52 eV, making it more suitable for electron injection. These intriguing properties are leveraged to demonstrate hole‐ and electron‐transporting OTFTs with improved operating characteristics. All‐organic complementary inverters are finally demonstrated by integrating p‐ and n‐channel OTFTs, showcasing the potential of this simple yet powerful contact work function engineering approach. The present study highlights the versatility of thiol carbazole SAMs as carrier injecting interlayers for OTFTs and integrated circuits.

AbstractSkeletal muscles represent a role model in soft robotics featuring agile locomotion and incredible mechanical robustness. However, existing actuators lack an optimal combination of actuation parameters (including actuation modes, work capacity, mechanical strength, and damage repair) to rival biological tissues. Here, a biomimetic structural design strategy via multilevel relaxations (α/β/γ/δ‐relaxation) modulation is proposed for mechanical robust and healable actuator materials with muscle‐like diastole and contraction abilities by orientational alignment of dendritic polyphenol‐modified nano‐assembles in eutectogels. The anisotropic hierarchical micro‐nanostructures assembled by supramolecular interaction mimic the relative slippage of actin filaments and myosin in muscles, ensuring bistable actuation through rapid thermal α‐relaxation and expansion. Furthermore, kinetically active secondary β/γ/δ‐relaxation at reconfigurable interfaces can conquer the limited self‐healing ability of fixed‐orientation polymeric chains. The obtained artificial muscle exhibits high output actuation, robust mechanical properties (tensile strength of 33.5 MPa), and desired functional, mechanical self‐healing efficiency (89.7%), exceeding typical natural muscles in living systems. The bionic micro‐nano design strategy achieves bottom‐up cooperative relaxation modulation to integrate all‐round performance of natural muscles, which paves the way for substantial advancements in next‐generation intelligent robotics.

AbstractUnder the guidance of the carbon peaking and carbon neutrality goals, the urgency for green ecological construction and the depletion of nonrenewable resources highlight the importance of the research and development of sustainable new materials. Cellulose nanofiber (CNF) is the most abundant natural nanoscale building block widely existing on Earth. CNF has unique intrinsic physical properties, such as low density, low coefficient of thermal expansion, high strength, and high modulus, which is an ideal candidate with outstanding potential for constructing sustainable materials. In recent years, CNF‐based structural material has emerged as a sustainable lightweight material with properties very different from traditional structural materials. Here, to comprehensively introduce the assembly of structural materials based on CNF, it starts with an overview of different forms of CNF‐based materials, including fibers, films, hydrogels, aerogels, and structural materials. Next, the challenges that need to be overcome in preparing CNF‐based structural materials are discussed, their assembly methods are introduced, and an in‐depth analysis of the advantages of the CNF‐based hydrogel assembly strategy to fabricate structural materials is conducted. Finally, the unique properties of emerging CNF‐based structural materials are summarized and concluded with an outlook on their design and functionalization, potentially paving the way toward new opportunities.

AbstractZn0 dendrite formation during repeated plating/stripping processes limits the practical use of Zn‐metal anodes in reliable and affordable energy storage. Traditional methods, including dendrite suppression and dendrite regulation, fail under demanding performance conditions due to Zn2+ diffusion limitations and concentration gradients. Here, using an in situ pre‐zincation approach, a Li2ZnxTi3‐xO8 (LZTO, 0<x<3) layer with uniform ion channels is introduced. This layer acts as an ionic sieve, reviving Zn0 dendrite into Zn2+ through redox reactions and enhancing Zn2+ diffusion kinetics. Experiment and simulation results reveal that Zn2+ migrates along the (111) crystal plane of LZTO through the successive replacement of Zn atoms in tetrahedral positions, with a high transference number of 0.796. LZTO@Zn performs better in coin cells at high currents (e.g., 50 mA cm−2) and operates at higher Zn utilization (300 h at 56.98% Zn utilization), with four times the lifespan at −40 °C and six times longer in alkaline electrolytes compared to bare Zn. Pouch cells with LZTO@Zn anodes operate in a low N/P ratio (6.9) and lean electrolyte (E/C is 20 µL mA h−1), achieving enhanced cycling stability. The findings indicate the significance of ion sieves with ordered ion channels in mitigating Zn0 dendrites and promoting rapid Zn2+ transport.

AbstractTraditional imaging systems struggle in weak or complex lighting environments due to their fixed spectral responses, resulting in spectral mismatches and degraded image quality. To address these challenges, a bioinspired adaptive broadband image sensor is developed. This innovative sensor leverages a meticulously designed type‐I heterojunction alignment of 0D perovskite quantum dots (PQDs) and 2D black phosphorus (BP). This configuration enables efficient carrier injection control and advanced computing capabilities within an integrated phototransistor array. The sensor's unique responses to both visible and infrared (IR) light facilitate selective enhancement and precise feature extraction under varying lighting conditions. Furthermore, it supports real‐time convolution and image restoration within a convolutional autoencoder (CAE) network, effectively countering image degradation by capturing spectral features. Remarkably, the hardware responsivity weights perform comparably to software‐trained weights, achieving an image restoration accuracy of over 85%. This approach offers a robust and versatile solution for machine vision applications that demand precise and adaptive imaging in dynamic lighting environments.

AbstractElectrical stimulation enhances cellular activity, promoting tissue regeneration and repair. However, specific cells and maintaining a stable energy supply are challenges for precise cell electrical stimulation therapy. Here, force‐electric conversion hydrogel microspheres (Piezo@CR MPs) is devloped to induce specific stem cell aggregation and promote chondrogenic differentiation through localized electrical stimulation. These MPs contain barium titanate (BT) nanoparticles embedded in hyaluronic acid methacrylate hydrogel MPs, with a polydopamine (pDA) coating bound to stem cell recruitment peptides (CR) via π‐π conjugation and electrostatic forces. Piezo@CR MPs convert pressure (ultrasound) into electrical stimulation, directing BMSCs for colonization and chondrogenesis. In vitro, directionally migrated stem cells almost covered the Piezo@CR MP surface, generating up to 451 mV of electrical output that enhanced chondrogenic differentiation. In a rabbit osteochondral defect model, Piezo@CR MPs promoted cartilage regeneration, nearly resembling native cartilage. In a rat osteoarthritis model, they reduced cartilage degeneration and improved behavioral outcomes. Additionally, Piezo@CR MPs promoted cartilage regeneration by driving the influx of extracellular calcium and activating the p38 mitogen‐activated protein kinase (MAPK) pathway. In conclusion, Piezo@CR MPs offer a new approach for precise cell type electrical stimulation therapy in treating of cartilage injuries and degeneration.

Published: December 2024

AbstractCellular differentiation is controlled by intricate layers of gene regulation, involving the modulation of gene expression by various transcriptional regulators. Due to the complexity of gene regulation, identifying master regulators across the differentiation trajectory has been a longstanding challenge. To tackle this problem, a computational framework, single‐cell Boolean network inference and control (BENEIN), is presented. Applying BENEIN to human large intestinal single‐cell transcriptome data, MYB, HDAC2, and FOXA2 are identified as the master regulators whose inhibition induces enterocyte differentiation. It is found that simultaneous knockdown of these master regulators can revert colorectal cancer cells into normal‐like enterocytes by synergistically inducing differentiation and suppressing malignancy, which is validated by in vitro and in vivo experiments.

Authors: Uddin Mohammad Burhan , Wang Zhishan , Yang Chengfeng 
Published: December 2024

AbstractSignificant advances in the development of new cancer therapies have given rise to multiple novel therapeutic options in chemotherapy, radiotherapy, immunotherapy, and targeted therapies. Although the development of resistance is often reported along with temporary disease remission, there is often tumor recurrence of an even more aggressive nature. Resistance to currently available anticancer drugs results in poor overall and disease‐free survival rates for cancer patients. There are multiple mechanisms through which tumor cells develop resistance to therapeutic agents. To date, efforts to overcome resistance have only achieved limited success. Epitranscriptomics, especially related to m6A RNA modification dysregulation in cancer, is an emerging mechanism for cancer therapy resistance. Here, recent studies regarding the contributions of m6A modification and its regulatory proteins to the development of resistance to different cancer therapies are comprehensively reviewed. The promise and potential limitations of targeting these entities to overcome resistance to various anticancer therapies are also discussed.

AbstractThe clinical efficacy of immune checkpoint blockade (ICB) therapy is significantly compromised in the metabolically disordered tumor microenvironment (TME), posing a formidable challenge that cannot be ignored in current antitumor strategies. In this study, TME‐responsive nanoparticles (HMP1G NPs) loaded with 1‐methyltryptophan (1‐MT; an indoleamine 2,3‐dioxygenase 1 [IDO1] inhibitor,) and S‐nitrosoglutathione (GSNO; a nitric oxide donor) is developed to enhance the therapeutic efficacy of 1‐MT‐mediated ICB. The HMP1G NPs responded to H+ and glutathione in the TME, releasing Mn2+, GSNO, and 1‐MT. The released Mn2+ catalyzed the production of abundant reactive oxygen species and nitric oxide from hydrogen peroxide and GSNO, and the generated nitric oxide, synergistically with 1‐MT, inhibited the accumulation of kynurenine mediated by IDO1 in the tumor. Mechanistically, HMP1G NPs downregulated tumor cell‐derived IDO1 via the aryl hydrocarbon receptor/signal transducer and activator of transcription 3/interleukin signaling axis to improve kynurenine/tryptophan metabolism and immunosuppression. In a murine breast cancer model, treatment with HMP1G NPs elicited effective antitumor immunity and enhanced survival outcomes. This study highlights a novel nano‐platform that simultaneously improves metabolism and enhances ICB efficacy to achieve a new and efficient antitumor strategy.

AbstractOxygen evolution reaction (OER) is an indispensable anode reaction for sustainable hydrogen production from water electrolysis, yet overreliance on metal‐based catalysts featured with vibrant d‐electrons. It still has notable gap between metal‐free and metal‐based electrocatalysts, due to lacking accurate and efficient p‐band regulation methods on non‐metal atoms. Herein, a molecular modularization strategy is proposed for fine‐tuning the p‐orbital states of series metal‐free covalent organic frameworks (COFs) for realizing OER performance beyond benchmark precious metal catalysts. Optimized combination of benzodioxazole/benzodiimide‐based building blocks achieves an impressive applied potential of 1.670 ± 0.004 V versus reversible hydrogen electrode (RHE) and 1.735 ± 0.006 V versus RHE to deliver enhanced current densities of 0.5 and 1.0 A cm−2, respectively. Moreover, it holds a notable charge transfer amount (stands for a long service life) within operation period that outperforms all reported metal‐free electrocatalysts. Operando differential electrochemical mass spectrometry (DEMS) with isotope labeling identifies the adsorbate evolution mechanism (AEM). A variety of spectroscopic techniques and density functional theory (DFT) calculations reveal that the p‐band center of these catalysts can be shifted stepwise to optimize the oxygen intermediate adsorption and lower the reaction energy barrier. This work provides a novel perspective for enhancing the electrocatalytic performance of metal‐free COFs.

AbstractRestricted and repetitive behavior (RRB) is a primary symptom of autism spectrum disorder (ASD), which poses a significant risk to individuals' health and is becoming increasingly prevalent. However, the specific cellular and neural circuit mechanisms underlying the generation of RRB remain unclear. In this study, it is reported that the absence of the ASD‐related protein Neuroligin 1 (NLGN1) in dopamine receptor D2‐expressing medium spiny neurons (D2‐MSNs) in the dorsal striatum is associated with the duration and frequency of self‐grooming and digging behaviors. The Nlgn1‐deficient D2‐MSNs are hyperactivated, which correlates with excessive self‐grooming and digging behaviors. Inhibiting the activity of D2‐MSNs reduces the duration and frequency of these RRBs. Furthermore, it is demonstrated that the generation of self‐grooming and digging behaviors depends on distinct patterns of D2‐MSN activity. Finally, through single‐nucleus RNA sequencing (sn‐RNAseq) and protein detection verification, it is revealed that the overactivation of protein kinase C (PKC) in Nlgn1‐deficient mice contributes to excessive repetitive behaviors and increased neuronal excitability. In this study, potential mechanisms are proposed for the generation of self‐grooming and digging behaviors, as well as suggest possible treatments and interventions ASD.

AbstractThis study reveals the mechanisms behind the ultralow lattice thermal conductivity κL in β‐Zn4Sb3 single crystals through inelastic neutron scattering (INS). Analyzing phonon behaviors and the interaction between acoustic phonons and rattling modes, the first experimental evidence of avoided crossing in β‐Zn4Sb3 is provided. The rattler‐phonon avoided crossings contribute to the low κL in a β‐Zn4Sb3 single crystal, enhancing the thermoelectric figure‐of‐merit (zT). TEM characterizations of the β‐Zn4Sb3 single crystal with intrinsic and ultralow κL reveal a grain‐boundary‐free structure with uniformly dispersed rotation moiré fringes that contribute to low lattice thermal conductivity while maintaining a uniform elemental distribution. Additionally, the significant impact of crystallinity control coupled with dilute doping on boosting thermoelectric performance, with single‐crystalline single leg outperforming their polycrystalline counterparts is demonstrated. Notably, the conversion efficiency η of the undoped β‐Zn4Sb3 single leg achieves 1.4% under a temperature gradient of 200 K.

Published: December 2024

AbstractMicrobes regulate many dimensions of plant performance with multiscale implications for plant fitness, competition, coexistence, and ecosystem functioning. Yet, this fascinating and diverse arena of study has been limited to a few thematic areas, ecosystems, and regions. In particular, despite growing evidence that microbes may be critical players in the dynamics of plant communities in tropical and subtropical ecosystems, these regions remain poorly represented in studies of plant–microbe interactions. Such geographical gaps limit our ability to draw general inferences to comprehend how microbial effects on plant community dynamics may vary with context and, by extension, respond to global environmental change. In this special section of the American Journal of Botany, we bring together a diverse set of research on plant–microbe interactions from tropical and subtropical ecosystems. These papers explore intraspecific variation of soil microbial communities, the context dependency of host‐specific assembly of microbial communities on plants, and the new and exciting frontier of the microbiome of epiphytic plants. We hope that this compilation will fuel deeper forays into the many dimensions of plant–microbe interactions in megadiverse tropical and subtropical forests.
