AbstractThe biosynthesis of Pd nanoparticles supported on microorganisms (bio‐Pd) is achieved via the enzymatic reduction of Pd(II) to Pd(0) under ambient conditions using inexpensive buffers and electron donors, like organic acids or hydrogen. Sustainable bio‐Pd catalysts are effective for C‐C coupling and hydrogenation reactions, but their industrial application is limited by challenges in controlling nanoparticle properties. Here, using the metal‐reducing bacterium Geobacter sulfurreducens, it is demonstrated that synthesizing bio‐Pd under different Pd loadings and utilizing different electron donors (acetate, formate, hydrogen, no e− donor) influences key properties such as nanoparticle size, Pd(II):Pd(0) ratio, and cellular location. Controlling nanoparticle size and location controls the activity of bio‐Pd for the reduction of 4‐nitrophenol, whereas high Pd loading on cells synthesizes bio‐Pd with high activity, comparable to commercial Pd/C, for Suzuki–Miyaura coupling reactions. Additionally, the study demonstrates the novel synthesis of microbially‐supported ≈2 nm PdO nanoparticles due to the hydrolysis of biosorbed Pd(II) in bicarbonate buffer. Bio‐PdO nanoparticles show superior activity in 4‐nitrophenol reduction compared to commercial Pd/C catalysts. Overall, controlling biosynthesis parameters, such as electron donor, metal loading, and solution chemistry, enables tailoring of bio‐Pd physicochemical and catalytic properties.

AbstractAll weather, high‐efficiency, energy‐saving anti‐icing/de‐icing materials are of great importance for solving the problem of ice accumulation on outdoor equipment surfaces. In this study, a composite material with energy storage, active electro‐/photo‐thermal de‐icing and passive super‐hydrophobic anti‐icing properties is proposed. Fluorinated epoxy resin and MWCNTs/PTFE particles are used to prepare the top multifunctional anti‐icing/de‐icing layer, which exhibited super‐hydrophobicity with water contact angle greater than 155° and conductivity higher than 69 S m−1. The super‐hydrophobic durability of the top layer is verified through tape peeling and sandpaper abrasion tests. The surface can be heated by applying on voltage or light illumination, showing efficient electro‐/photo‐thermal and all‐day anti‐icing/de‐icing performance. The oleogel material at the bottom layer is capable to absorb energy during heating process and release it during cooling process by phase transition, which greatly delayed the freezing time and saved energy. The icing test of single ice droplet, electro‐/photo‐thermal de‐icing and defrosting tests also proved the high efficiency and energy saving of the anti‐icing/de‐icing strategy. This study provided a new way to manufacture multi‐functional materials for practical anti‐icing/de‐icing applications.

AbstractA complex electromagnetic environment is a formidable challenge in national defense areas. Microwave‐absorbing materials are considered as a strategy to tackle this challenge. In this work, lightweight, flexible, and thermal insulating Carbon/SiO2@CNTs (CSC) aerogel is successfully prepared coupled with outstanding microwave absorbing performance, through freeze‐drying and high‐temperature annealing techniques. The CSC aerogel shows a strong reflection loss (−55.16 dB) as well as wide effective absorbing bandwidth (8.5 GHz) in 2–18 GHz. It also retains good microwave absorption properties under tension and compression. Radar cross‐sectional (RCS) simulation result demonstrates the CSC processing a strong reduction ability of RCS compared with a metal plate. Further exploration shows amazing flexibility and good thermal insulation properties of CSC. The successful preparation of this composite aerogel provides a broad prospect for the design of microwave‐absorbing materials.

AbstractThe photocatalytic environmental decontamination ability of carbon nitride (g‐C3N4, CN) typically suffers from their inherent structural defects, causing rapid recombination of photogenerated carriers. Conjugating CN with tailored donor–acceptor (D–A) units to counteract this problem through electronic restructuring becomes a feasible strategy, where confirmation by density functional theory (DFT) calculations becomes indispensable. Herein, DFT is employed to predirect the copolymerization modification of CN by benzene derivatives, screening benzaldehyde as the optimal electron‐donating candidate for the construction of reoriented intramolecular charge transfer path. Experimental characterization and testing corroborate the formation of a narrowed bandgap as well as high photoinduced carrier separation. Consequently, the optimal BzCN‐2 exhibited superior photocatalytic capacity in application for tetracycline hydrochloride degradation, with 3.73 times higher than that of CN. Besides, the BzCN‐2‐based photocatalytic system is determined to have a toxicity‐mitigating effect on TC removal via T.E.S.T and prefers the removal of dissociable TC2− species under partial alkalinity. This work provides insight into DFT guidance for the design of D–A conjugated polymer and its application scenarios in photocatalytic decontamination.

AbstractThe atomically dispersed Fe‐N4 active site presents enormous potential for various renewable energy conversions. Despite its already remarkable catalytic performance, the local atomic microenvironment of each Fe atom can be regulated to further enhance its efficiency. Herein, a novel conceptual strategy that utilizes a simple salt‐template polymerization method to simultaneously adjust the first coordination shell (Fe‐N3S1) and second coordination shell (C–S–C, a structure similar to thiophene) of Fe‐N4 isolated atoms is proposed. Theoretical studies suggest that this approach can redistribute charge density in the MN4 moiety, lowering the d‐band center of the metal site. This weakens the binding of oxygenated intermediates, enhancing oxygen reduction reaction (ORR) activity when compared to only implementing coordination shell regulation. Based on the above discovery, a single Fe atom electrocatalyst with the optimal Fe‐N3S1‐S active moiety incorporated in nitrogen, sulfur co‐doped graphene (Fe‐SAc/NSG) is designed and synthesized. The Fe‐SAc/NSG catalyst exhibits excellent alkaline ORR activity, exceeding benchmark Pt/C and most Fe‐SAc ORR electrocatalysts, as well as superior stability in Zn–air battery. This work aims to pave the way for creating highly active single metal atom catalysts through the localized regulation of their atomic structure.

AbstractCarbon‐defect engineering in single‐atom metal‐nitrogen‐carbon (M─N─C) catalysts by straightforward and robust strategy, enhancing their catalytic activity for volatile organic compounds, and uncovering the carbon vacancy‐catalytic activity relationship are meaningful but challenging. In this study, an iron‐nitrogen‐carbon (Fe─N─C) catalyst is intentionally designed through a carbon‐thermal‐diffusion strategy, exposing extensively the carbon‐defective Fe─N4 sites within a micro‐mesoporous carbon matrix. The optimization of Fe─N4 sites results in exceptional catalytic ozonation efficiency, surpassing that of intact Fe─N4 sites and commercial MnO2 by 10 and 312 times, respectively. Theoretical calculations and experimental data demonstrated that carbon‐defect engineering induces selective cleavage of C─N bond neighboring the Fe─N4 motif. This induces an increase in non‐uniform charges and Fermi density, leading to elevated energy levels at the center of Fe d‐band. Compared to the intact atomic configuration, carbon‐defective Fe─N4 site is more activated to strengthen the interaction with O3 and weaken the O─O bond, thereby reducing the barriers for highly active surface atomic oxygen (*O/*OO), ultimately achieving efficient oxidation of CH3SH and its intermediates. This research not only offers a viable approach to enhance the catalytic ozonation activity of M─N─C but also advances the fundamental comprehension of how periphery carbon environment influences the characteristics and efficacy of M─N4 sites.

AbstractOptimizing the electrode/electrolyte interface structure is the key to realizing high‐voltage Li‐metal batteries (LMBs). Herein, a functional electrolyte is introduced to synergetically regulate the interface layer structures on the high‐voltage cathode and the Li‐metal anode. Saccharin sodium (NaSH) as a multifunctional electrolyte additive is employed in fluorinated solvent‐based electrolyte (FBE) for robust interphase layer construction. On the one hand, combining the results of ex‐situ techniques and in‐situ electrochemical dissipative quartz crystal microbalance (EQCM‐D) technique, it can be seen that the solid electrolyte interface (SEI) layer constructed by NaSH‐coupled fluoroethylene carbonate (FEC) on Li‐metal anode significantly inhibits the growth of lithium dendrites and improves the cyclic stability of the anode. On the other hand, the experimental results also confirm that the cathode‐electrolyte interface (CEI) layer induced by NaSH‐coupled FEC effectively protects the active materials of LiCoO2 and improves their structural stability under high‐voltage cycling, thus avoiding the material rupture. Moreover, theoretical calculation results show that the addition of NaSH alters the desolvation behavior of Li+ and enhances the transport kinetics of Li+ at the electrode/electrolyte interface. In this contribution, the LiCoO2ǁLi full cell containing FBE+NaSH results in a high capacity retention of 80% after 530 cycles with a coulombic efficiency of 99.8%.

AbstractDouble‐borylated multiple‐resonance (MR) skeletons are promising templates for high performance, while the chemical design space is relatively limited. Peripheral segments are often used to decorate/fuse MR skeletons and modulate the photophysics but they can also cause unwanted spectral broadening. Herein, a narrowband MR emitter ICzDBA by fusing an MR‐featured donor segment indolocarbazole into a double‐borylated MR skeleton is developed. In ICzDBA, the nitrogen atom located away from the core benzene ring can also contribute to the generation of the overall MR‐featured distribution through the long‐range conjugation effect, along with the other boron/nitrogen atoms on the phenyl center. Thus, ICzDBA in toluene displays a narrowband emission peaking at 507 nm with a full width at half maximum of merely 20 nm (0.09 eV). Moreover, organic light‐emitting diode devices using ICzDBA emitter exhibit ultrapure green emission with Commission Internationale de l'Eclairage (CIE) coordinates of (0.27, 0.70) and a high external quantum efficiency of 32.5%. These results manifest the importance of MR characters of peripheral decorations/fusions in preserving the narrowband features of MR skeletons, which provides a solution for further expanding MR structures with well‐maintained narrowband characters.

AbstractMost mechanochromic luminescent compounds are crystalline and highly hydrophobic; however, mechanochromic luminescent molecular assemblies comprising amphiphilic molecules have rarely been explored. This study investigated mechanochromic luminescent supramolecular fibers composed of dumbbell‐shaped 9,10‐bis(phenylethynyl)anthracene‐based amphiphiles without any tetraethylene glycol (TEG) substituents or with two TEG substituents. Both amphiphiles formed water‐insoluble supramolecular fibers via linear hydrogen bond formation. Both compounds acquired water solubility when solid samples composed of supramolecular fibers are ground. Grinding induces the conversion of 1D supramolecular fibers into micellar assemblies where fluorophores can form excimers, thereby resulting in a large redshift in the fluorescence spectra. Excimer emission from the ground amphiphile without TEG chains is retained after dissolution in water. The micelles are stable in water because hydrophilic dendrons surround the hydrophobic luminophores. By contrast, when water is added to a ground amphiphile having TEG substituents, fragmented supramolecular fibers with the same molecular arrangement as the initial supramolecular fibers are observed, because fragmented fibers are thermodynamically preferable to micelles as the hydrophobic arrays of fluorophores are covered with hydrophilic TEG chains. This leads to the recovery of the initial fluorescent properties for the latter amphiphile. These supramolecular fibers can be used as practical mechanosensors to detect forces at the mesoscale.

AbstractOwing to the high economic efficiency and energy density potential, manganese‐based layer‐structured oxides have attracted great interests as cathode materials for potassium ion batteries. In order to alleviate the continuous phase transition and K+ re‐embedding from Jahn‐Teller distortion, the [Mn‐Co‐Mo]O6 octahedra are introduced into P3‐K0.45MnO2 herein to optimize the local electron structure. Based on the experimental and computational results, the octahedral center metal molybdenum in [MoO6] octahedra proposes a smaller ionic radius and higher oxidation state to induce second‐order JTE (pseudo‐JTE) distortion in the adjacent [MnO6] octahedra. This distortion compresses the [MnO6] octahedra along the c‐axis, leading to an increased interlayer spacing in the K+ layer. Meanwhile, the Mn3+/Mn4+ is balanced by [CoO6] octahedra and the K+ diffusion pathway is optimized as well. The proposed P3‐K0.45Mn0.9Co0.05Mo0.05O2 cathode material shows an enhanced cycling stability and rate performance. It demonstrates a high capacity of 80.2 mAh g−1 at 100 mAh g−1 and 77.3 mAh g−1 at 500 mAh g−1. Furthermore, it showcases a 2000 cycles stability with a 59.6% capacity retention. This work presents a promising solution to the challenges faced by manganese‐based layered oxide cathodes and offers a deep mechanism understanding and improved electrochemical performance.

AbstractVanadium‐based polyanionic materials are promising electrode materials for sodium‐ion batteries (SIBs) due to their outstanding advantages such as high voltage, acceptable specific capacity, excellent structural reversibility, good thermal stability, etc. Polyanionic compounds, moreover, can exhibit excellent multiplicity performance as well as good cycling stability after well‐designed carbon covering and bulk‐phase doping and thus have attracted the attention of multiple researchers in recent years. In this paper, after the modification of carbon capping and bulk‐phase nitrogen doping, compared to pristine Na3V2(PO4)3, the well optimized Na3V(PO3)3N/C possesses improved electromagnetic induction strength and structural stability, therefore exhibits exceptional cycling capability of 96.11% after 500 cycles at 2 C (1 C = 80 mA g−1) with an elevated voltage platform of 4 V (vs Na+/Na). Meanwhile, the designed Na3V(PO3)3N/C possesses an exceptionally low volume change of ≈0.12% during cycling, demonstrating its quasi‐zero strain property, ensuring an impressive capacity retention of 70.26% after 10,000 cycles at 2 C. This work provides a facial and cost‐effective synthesis method to obtain stable vanadium‐based phosphate materials and highlights the enhanced electrochemical properties through the strategy of carbon rapping and bulk‐phase nitrogen doping.

Published: March 2024

AbstractAlthough there are various advancements in biomedical in the past few decades, there are still challenges in the treatment of brain diseases. The main difficulties are the inability to deliver a therapeutic dose of the drug to the brain through the blood‐brain barrier (BBB) and the serious side effects of the drug. Thus, it is essential to select biocompatible drug carriers and novel therapeutic tools to better enhance the effect of brain disease treatment. In recent years, biomimetic nanoparticles (BNPs) based on natural cell membranes, which have excellent biocompatibility and low immunogenicity, are widely used in the treatment of brain diseases to enable the drug to successfully cross the BBB and target brain lesions. BNPs can prolong the circulation time in vivo, are more conducive to drug aggregation in brain lesions. Cell membranes (CMs) from cancer cells (CCs), red blood cells (RBCs), white blood cells (WBCs), and so on are used as biomimetic coatings for nanoparticles (NPs) to achieve the ability to target, evade clearance, or stimulate the immune system. This review summarizes the application of different cell sources as BNPs coatings in the treatment of brain diseases and discusses the possibilities and challenges of clinical translation.

AbstractNanoformulations with endogenous/exogenous stimulus‐responsive characteristics show great potential in tumor cell elimination with minimal adverse effects and high precision. Herein, an intelligent nanotheranostic platform (denoted as TPZ@Cu‐SnS2‐x/PLL) for tumor microenvironment (TME) and near‐infrared light (NIR) activated tumor‐specific therapy is constructed. Copper (Cu) doping and the resulting sulfur vacancies can not only improve the response range of visible light but also improve the separation efficiency of photogenerated carriers and increase the carrier density, resulting in the ideal photothermal and photodynamic performance. Density functional theory calculations revealed that the introduction of Cu and resulting sulfur vacancies can induce electron redistribution, achieving favorable photogenerated electrons. After entering cells through endocytosis, the TPZ@Cu‐SnS2‐x/PLL nanocomposites show the pH responsivity property for the release of the TPZ selectively within the acidic TME, and the released Cu2+ can first interact with local glutathione (GSH) to deplete GSH with the production of Cu+. Subsequently, the Cu+‐mediated Fenton‐like reaction can decompose local hydrogen peroxide into hydroxyl radicals, which can also be promoted by hyperthermia derived from the photothermal effect for tumor cell apoptosis. The integration of photoacoustic/computed tomography imaging‐guided NIR phototherapy, TPZ‐induced chemotherapy, and GSH‐elimination/hyperthermia enhanced chemodynamic therapy results in synergistic therapeutic outcomes without obvious systemic toxicity in vivo.
