AbstractDeveloping efficient oxygen electrocatalysts with low cost, high catalytic activity, and robust stability remains a formidable challenge for rechargeable zinc–air batteries (ZABs). Herein, highly dispersed ultrasmall PtPdFeCoNi high‐entropy alloy nanoparticles with a size of ≈ 2 nm and randomly distributed multimetallic single atoms spatially immobilized on the 3D hierarchically ordered porous nitrogen‐doped carbon skeleton (denoted as PtPdFeCoNi/HOPNC) are successfully synthesized via ultra‐rapid Joule heating process. The spatial immobilization on 3D HOPNC skeleton is the key to the high dispersion of multi‐active sites of oxygen electrocatalysts, and the formed hierarchical pore structure is conducive to the successful construction of the rapid mass transfer channel. As a result, the as‐prepared PtPdFeCoNi/HOPNC exhibits a positive half‐wave potential of 0.866 V versus RHE for oxygen reduction reaction (ORR), a low overpotential of 310 mV at 10 mA cm−2 for oxygen evolution reaction (OER), and low Tafel slopes for both ORR and OER. Furthermore, ZAB using PtPdFeCoNi/HOPNC as bifunctional oxygen catalysts exhibits excellent rate performances and superior cycling stability, surpassing that of a commercial Pt/C‐RuO2 mixture. The spatial immobilization strategy of HOPNC provides a new idea for the design and synthesis of efficient catalysts for various applications.

AbstractPassive radiative cooling, as a cooling technique with no energy input, can continuously radiate heat into the supercooled universe. However, the continuous cooling effect tends to cause the problem of nighttime overcooling. Moreover, non‐renewable radiative cooling materials and energy‐intensive processing methods lead to increased carbon emissions and resource consumption. Therefore, there is an urgent need to develop a renewable and environmentally friendly self‐adaption radiative cooling thermal management material. In this paper, a high‐performance self‐adaption thermal management wood composite aerogel material is designed and prepared by in situ growth of multi‐scale silicon dioxide on wood. The constructed passive radiative cooling material has a sub‐ambient cooling effect of up to 13.5 °C and 20.2 °C during daytime in winter and summer, respectively. Meanwhile, it has a certain thermal insulation performance (2.0 °C above ambient) due to low thermal conductivity (0.063370 ± 0.000329 W m−1 k−1) at night in winter. In addition, the material is also suitable for fog–water harvesting (fog–water harvesting rate of 59.27 ± 0.76 mg min−1) due to its hydrophobicity. This work can significantly promote the practical application of passive radiative cooling materials.

Published: October 2024

AbstractAchieving amorphous polymers with ultralong room‐temperature phosphorescence (RTP), tunable organic afterglow, and reversible photoactivation behavior is highly desirable for practical applications but challenging. Herein, simple positional isomers with three carboxyl groups located in the ortho, meta, and para positions of the triphenylamine skeleton are designed and synthesized. By physically blending with the poly(vinyl alcohol) matrix, these isomers show ultralong RTP properties, among which the meta‐isomer has the longest RTP lifetime (620.1 ms). Theoretical calculations reveal that the more efficient intersystem crossing, the slower radiative decay rate of the lowest triplet excitons, and stronger intermolecular hydrogen‐bonding interactions should be responsible for the superior RTP property of meta‐isomer. Furthermore, the tunable organic afterglow is readily realized via a triplet‐to‐singlet energy transfer process. More impressively, the meta and para isomers exhibit reversible photoactivated ultralong RTP properties after embedding into the rigid poly(methyl methacrylate) matrix. Finally, amorphous and flexible polymer films prepared from these positional isomers show potential applications in advanced anti‐counterfeiting and multilevel encryption through subtly combining ultralong RTP lifetime, tunable organic afterglow, and reversible photoactivation behavior.

Published: October 2024

AbstractBurn wound healing is a dynamic and interconnected process, with the complex status of the extracellular matrix (ECM) potentially leading to bacterial infections, drug resistance, or even fatality. However, it remains a grand challenge to assemble a skin‐like material showing similar biological properties as healthy ECM to accelerate burn healing. In this study, the ECM composition is closely mimicked and adaptive multifunctional artificial dermis is developed by leveraging Ag─S bonds, supramolecular interactions among recombinant proteins, Ag+, and hyaluronic acid (HA). The artificial dermis exhibits long‐lasting broad‐spectrum antibacterial activity, achieved though controlled Ag+ release via Ag─S bonds, supramolecular interactions, and recombinant protein‐guided multi‐level assembly, reaching a steady plateau of 83.7% in the later stage. It is found that inflammation is reduced by downregulating IL‐6 and TGF‐β expression. Furthermore, the epidermal growth factor (EGF) within the recombinant proteins stimulates Col1α, ELN, and CD31 upregulation, facilitating ECM remodeling. These adaptive multifunctional artificial dermis effectively address wound infections, accelerate collagen deposition, promote re‐epithelialization, and enhance angiogenesis in infected wounds, highlighting their potential to revolutionize burn wound treatment and offering a promising avenue to holistic care.

Published: October 2024

AbstractZeolite imidazole‐based framework (ZIF‐67), a notable class of metal–organic frameworks (MOFs), shows promise in activating peroxymonosulfate (PMS) for pollutant degradation due to its uniformly distributed cobalt ions. However, its nanoparticle form and the elution of cobalt ions during use cause challenges in recycling and the risk of secondary pollution. In this study, a magnetic core‐shell hydrogen‐bonded organic framework (HOF) on the MOF (HOF‐on‐Fe3O4/ZIF‐67) is successfully prepared. The porous HOF shell not only protects the active sites and mitigates cobalt ion leaching but also reduces mass transfer limitations, ensuring sustained catalytic performance. The magnetic Fe3O4 core enhances electron transfer between cobalt ions, boosts catalytic efficiency, and facilitates easy separation and recycling. This core‐shell structure effectively activates PMS, achieving 100% removal of Rhodamine B, a model wastewater dye, within 10 min (Rh B = 50 mg L−1, HFZ = 150 mg L−1, PMS = 1.5 mm, pH = 7, room temperature). Furthermore, under the protection of the HOF shell, cobalt ion leaching is minimized to a negligible value (0.14 mg L−1) after 5 cycles of use. The research provides fresh perspectives into the development of core‐shell composite materials with improved performance and recyclability in wastewater treatment.

AbstractThe practical implementation of aqueous Zn‐ion batteries presents formidable hurdles, including uncontrolled dendrite growth, water‐induced side reactions, suboptimal Zn metal utilization, and intricate Zn anode manufacturing. Here, large‐scale construction of a highly oriented ZnO(002) lattice plane on Zn anode (ZnO(002)@Zn) with thermodynamic inertia and kinetic zincophilicity is designed to address such problems. Both theoretical calculations and experiment results elucidate that the ZnO(002)@Zn possesses high Zn chemical affinity, hydrogen evolution reaction suppression, and dendrite‐free deposition ability due to the abundant lattice oxygen species in ZnO(002) and its low lattice mismatch with Zn(002). These features synergistically promote ion transport and enable homogeneous Zn deposition. Consequently, the ZnO(002)@Zn anode displays a stable and prolonged cycling lifespan exceeding 500 h even under a larger depth of discharge (85.6%) and realizes an impressive average Coulombic efficiency of 99.7%. Moreover, its efficacy is also evident in V2O5‐cathode coin cells and pouch cells with not only high discharge capacity but also exceptional cycling stability. This integrated approach presents a promising avenue for addressing the challenges associated with Zn metal anodes, thereby advancing the prospects of aqueous Zn‐ion battery technologies.

AbstractThe design and fabrication of materials that can concurrently respond to light and gas within the dual‐modal recognition domain present a significant challenge due to contradictory structural requirements. This innovative strategy introduces a type‐I heterojunction, combining the properties of Sb2Te3 and WSe2 nanosheets, to overcome these obstacles. The heterojunction is prepared through a precise stacking approach to create a single‐side barrier on the valence band and a near‐zero offset on the conduction band. The resulting Sb2Te3/WSe2 heterojunction demonstrates unparalleled performance, showcasing the best integrated photoelectric and gas sensing performance in a single device to date. Based on the above features, the heterojunction successfully integrates visual and olfactory sensing performance, achieving the first biomimetic visual‐olfactory dual‐mode recognition in a single device. This simulation increased the accuracy of distinguishing electric and fuel‐powered cars from ≈50% to ≈96%. This work introduces a novel approach to creating efficient, self‐powered sensing materials, paving the way for next‐generation biomimetic dual‐model devices with broad applications in environmental protection, medical care, and other fields.

AbstractElectromagnetic (EM) wave pollution and thermal damage pose serious hazards to delicate instruments. Functional aerogels offer a promising solution by mitigating EM interference and isolating heat. However, most of these materials struggle to balance thermal protection with microwave absorption (MA) efficiency due to a previously unidentified conflict between the optimizing strategies of the two properties. Herein, this study reports a solution involving the design of a carbon‐based aerogel called functional carbon spring (FCS). Its unique long‐range lamellar multi‐arch microstructure enables tunable MA performance and excellent thermal insulation capability. Adjusting compression strain from 0% to 50%, the adjustable effective absorption bandwidth (EAB) spans up to 13.4 GHz, covering 84% of the measured frequency spectrum. Notably, at 75% strain, the EAB drops to 0 GHz, demonstrating a novel “on‐off” switchability for MA performance. Its ultralow vertical thermal conductivity (12.7 mW m−1 K−1) and unique anisotropic heat transfer mechanism endow FCS with superior thermal protection effectiveness. Numerical simulations demonstrate that FCS outperforms common honeycomb structures and isotropic porous aerogels in thermal management. Furthermore, an “electromagnetic‐thermal” dual‐protection material database is established, which intuitively demonstrates the superiority of the solution. This work contributes to the advancement of multifunctional MA materials with significant potential for practical applications.

AbstractTwo near‐infrared (NIR) emissive π‐conjugated covalent organic frameworks (COFs) pTANG1 and pTANG2 are synthesized using Knoevenagel condensation of trioxaazatriangulenetricarbaldehyde (TATANG) with benzene‐ and biphenyldiacetonitriles, respectively. The morphology of the COFs is affected by the size of TATANG precursor crystals. Donor–acceptor interactions in these COFs result in small bandgaps (≈1.6 eV) and NIR emission (λmax = 789 nm for pTANG1). pTANG1 can absorb up to 9 molecules of water per unit cell, which is accompanied by a marked quenching of the NIR emission, suggesting applications as humidity sensors. p‐Doping with magic blue significantly increases the electrical conductivities of the COFs by up to 8 orders of magnitude, with the room temperature conductivity of pTANG1 reaching 0.65 S cm−1, the highest among reported C═C linked COFs. 1H NMR relaxometry, temperature‐dependent fluorescence spectroscopy, and DFT calculations reveal that the higher rigidity of the shorter phenylene linker is responsible for the more extended conjugation (red‐shifted emission, higher electrical conductivity) of pTANG1 compared to pTANG2.

AbstractA bottleneck in the development of new anti‐cancer drugs is the recognition of their mode of action (MoA). Metabolomics combined with machine learning allowed to predict MoAs of novel anti‐proliferative drug candidates, focusing on human prostate cancer cells (PC‐3). As proof of concept, 38 drugs are studied with known effects on 16 key processes of cancer metabolism, profiling low molecular weight intermediates of the central carbon and cellular energy metabolism (CCEM) by LC‐MS/MS. These metabolic patterns unveiled distinct MoAs, enabling accurate MoA predictions for novel agents by machine learning. The transferability of MoA predictions based on PC‐3 cell treatments is validated with two other cancer cell models, i.e., breast cancer and Ewing's sarcoma, and show that correct MoA predictions for alternative cancer cells are possible, but still at some expense of prediction quality. Furthermore, metabolic profiles of treated cells yield insights into intracellular processes, exemplified for drugs inducing different types of mitochondrial dysfunction. Specifically, it is predicted that pentacyclic triterpenes inhibit oxidative phosphorylation and affect phospholipid biosynthesis, as confirmed by respiration parameters, lipidomics, and molecular docking. Using biochemical insights from individual drug treatments, this approach offers new opportunities, including the optimization of combinatorial drug applications.
Hydroxypropyl Cellulose‐Based Meter‐Long Structurally Colored Fibers for Advanced Fabrics
Authors: Qin Qinan , Xu Yan 
Published: October 2024

AbstractStructurally colored fibers are attractive alternatives to chemically colored fibers due to their rich optical properties, color stability, and environmental friendliness. However, the fabrication of structurally colored fibers using cost‐effective raw materials with the possibility to scale up remains challenging. Here, a simple and scalable approach is developed to fabricate continuous meter‐long structurally colored fibers exhibiting brilliant structural colors across the visible spectrum and helix orientation‐dependent polarization states. The fibers are fabricated by extrusion of concentrated aqueous solutions of chemically crosslinked hydroxypropyl cellulose (HPC). The wavelengths and polarization states can be tuned by solution concentration, relaxation time, and collector's surface energy. The HPC‐based structurally colored fibers display excellent optical stability to mechanical straining, repeated drying/water impregnation, and prolonged heating at 150 °C. It is demonstrated that the HPC‐based structurally colored fibers can be woven into structurally colored fabrics with wavelength‐ and polarization‐coded optical patterns. The current work presents a strategy to tune the chiral nematic order, which constitutes an important step toward mass production of structurally colored fibers with stable and rich optical properties using easily available raw materials.

AbstractHost mitochondria undergo fission and fusion, which bacteria often exploit for their infections. In this study, the underlying molecular mechanisms are aimed to clarify through which Listeria monocytogenes (L. monocytogenes), a human bacterial pathogen, manipulates mitochondrial dynamics to enhance its pathogenicity. It is demonstrated that L. monocytogenes triggers transient mitochondrial fission through its virulence factor listeriolysin O (LLO), driven by LLO's interaction with Mic60, a core component of the mitochondrial contact site and the cristae organizing system (MICOS). Specifically, Phe251 within LLO is identify as a crucial residue for binding to Mic60, crucial for LLO‐induced mitochondrial fragmentation and bacterial pathogenicity. Importantly, it is that Mic60 affect the formation of F‐actin tails recruited by L. monocytogenes, thereby contributing to intracellular bacterial infection. Mic60 plays a critical role in mediating changes in mitochondrial morphology, membrane potential, and reactive oxidative species (ROS) production, and L. monocytogenes infection exacerbates these changes by affecting Mic60 expression. These findings unveil a novel mechanism through which intracellular bacteria exploit host mitochondria, shedding light on the complex interplay between hosts and microbes during infections. This knowledge holds promise for developing innovative strategies to combat bacterial infections.

AbstractAntimony sulfide (Sb2S3) has attracted much attention due to its great prospect to construct highly efficient, cost‐effective, and environment‐friendly solar cells. The scalable close‐spaced sublimation (CSS) is a well‐developed physical deposition method to fabricate thin films for photovoltaics. However, the CSS‐processed absorber films typically involve small grain size with high‐density grain boundaries (GBs), resulting in severe defects‐induced charge‐carrier nonradiative recombination and further large open‐circuit voltage (VOC) losses. In this work, it is demonstrated that a chemical bath deposited‐Sb2S3 seed layer can serve as crystal nuclei and mediate the growth of large‐grained, highly compact CSS‐processed Sb2S3 films. This seed‐mediated Sb2S3 film affords reduced defect density and enhanced charge‐carrier transport, which yields an improved power conversion efficiency (PCE) of 4.78% for planar Sb2S3 solar cells. Moreover, the VOC of 0.755 V that is obtained is the highest reported thus far for vacuum‐based evaporation and sublimation processed Sb2S3 devices. This work demonstrates an effective strategy to deposit high‐quality low‐defect‐density Sb2S3 films via vacuum‐based physical methods for optoelectronic applications.

AbstractThe electrocatalytic conversion of carbon dioxide (CO2) into valuable multicarbon (C2+) compounds offers a promising approach to mitigate CO2 emissions and harness renewable energy. However, achieving precise selectivity for specific C2+ products, such as ethylene and ethanol, remains a formidable challenge. This study shows that incorporating elemental boron (B) into copper (Cu) catalysts provides additional adsorption sites for *CO intermediates, enhancing the selectivity of desirable C2+ products. Additionally, using a nickel single‐atom catalyst (Ni‐SAC) as a *CO source increases local *CO concentration and reduces the hydrogen evolution reaction. In situ experiments and density functional theory (DFT) calculations reveal that surface‐bound boron units adsorb and convert *CO more efficiently, promoting ethylene production, while boron within the bulk phase of copper influences charge transfer, facilitating ethanol generation. In a neutral electrolyte, the bias current density for ethylene production using the B‐O‐Cu2@Ni‐SAC0.05 hybrid catalyst exceeded 300 mA cm−2, and that for ethanol production with B‐O‐Cu5@Ni‐SAC0.2 surpassed 250 mA cm−2. This study underscores that elemental doping in Cu‐based catalysts not only alters charge and crystalline phase arrangements at Cu sites but also provides additional reduction sites for coupling reactions, enabling the efficient synthesis of distinct C2+ products.
