Published: February 2025

AbstractSpecific regulation of the tumor microenvironment (TME) is a potential strategy for tumor therapy. Although many TME‐responsive nanozymes have been developed for tumor therapy, the limited substrates affect the therapeutic effect. In this study, cerium single‐atom nanozymes (Ce SAs) are prepared by immobilizing cerium (Ce) using zeolitic imidazolate framework‐8 (ZIF‐8) as a precursor. The reversible conversion between Ce3+ and Ce4+ endows Ce SAs with multiple enzyme‐like activities, such as peroxidase (POD)‐like activity, oxidase (OD)‐like activity, catalase (CAT)‐like activity, glucose oxidase (GOD)‐like activity, and glutathione peroxidase (GSH‐Px)‐like activity. All of the above enzyme activities give Ce SAs cascade self‐circulation properties and can be used for tumor therapy in the TME. In addition, the prepared Ce SAs also have photothermal properties, which can achieve photothermal therapy (PTT) of tumor cells under 808 nm near‐infrared (NIR) irradiation. Combining the cascade self‐cycling enzyme‐like activities and the photothermal properties of Ce SAs, this synergistic therapy makes Ce SAs have attractive efficacy in tumor treatment.

AbstractHydrogen peroxide (H2O2) is an environmentally friendly and efficient oxidant with diverse applications in the chemical industry, medicine, energy, and environmental protection. While the anthraquinone oxidation process has traditionally dominated industrial H2O2 production, its complexity and high pollution levels present significant challenges. In response, alternative methods such as electrochemical, photochemical, and photoelectrochemical pathways have emerged, providing greener and more sustainable solutions. These innovative approaches leverage only water, oxygen, and solar or electrical energy, positioning them as viable substitutes for the energy‐intensive anthraquinone process. This review delves into the latest advancements in H2O2 production through the twoelectron oxygen reduction reaction (2e−ORR), twoelectron water oxidation reaction (2e−WOR), and the synergistic two‐channel pathway (2e−ORR + 2e−WOR) in (photo)electrochemical systems, focusing on reaction pathways. It discusses underlying mechanisms, evaluation parameters, and the design of high‐performance catalysts for on‐site H2O2 production in environmental applications. Recent developments in advanced (photo)electrocatalysts over the past five years are highlighted, including key design strategies that enhance catalytic performance. The review also addresses future challenges and prospects in catalyst design and practical environmental applications of (photo)electrochemical systems for H2O2 production, serving as a valuable reference for researchers in the field.

AbstractAir pollution has emerged as a global challenge, posing significant threats to public health and human well being. This issue has garnered substantial attention from researchers focused on developing environmentally friendly and sustainable materials. This study synthesizes bacterial cellulose (BC)‐derived aerogels based on plant polysaccharides and BC using a directional freeze‐drying technique, followed by surface modification with methyltrimethoxysilane (MTMS). The physicochemical characteristics of these BC‐derived aerogels are thoroughly investigated to elucidate the interaction mechanisms between plant polysaccharides and bacterial cellulose at the molecular level, and their capabilities for particulate matter filtration are explored. The results demonstrate that incorporating plant polysaccharides and MTMS into BC aerogels results in synergistic mechanical properties characterized by a unique combination of softness and rigidity. Notably, sodium alginate shows the highest affinity for bacterial cellulose and MTMS, leading to optimal reinforcement effects. An oriented honeycomb structure forms internally within the aerogels, potentially reducing pressure drop. Furthermore, these aerogels exhibit a “fiber+pore” multi‐filtration mechanism, achieving up to 97% filtration efficiency specifically for PM2.5 particles. These findings suggest bacterial cellulose‐derived aerogels could be a sustainable alternative for mitigating air pollution.

Published: February 2025

AbstractPolymetallic MOFs heterostructural composites enhance their usage in a range of sensing domains by combining two or more different MOFs to produce a new MOF‐on‐MOF integrated module. As its widespread utilization of flavomycin (Fla), there are currently complications with agricultural residue and the environment, consequently, a highly sensitive, portable technology for identification will be required to handle environmental monitoring in real‐time. In this work, the structural characterization and characteristics of the two‐layer MOF‐on‐MOF heterostructure are investigated using the epitaxial growth method. Electrons migrate from the Fe metal center to the organic ligand primarily as a result of hydrogen bonding between Fla and the surface of Fe‐MOF and energy transfer amongst the Fe atoms and NH2‐MIL‐101 (Eu). The synergistic impact of NH2‐MIL‐101(Eu) and Fe‐MOF improves the sensitivity and accuracy of detection, which has a 4.8 nm detection limit, enabling the high sensitivity detection of Fla. Likewise, we put together a handheld sensing platform incorporating aerogel and sensing materials that can meet the expectations of real‐time monitoring and multiple actual sample detection, and fluorescent MOFs materials offer an innovative viewpoint on the application of creating flexible sensors, enabling a new method of visualization for food safety and environmental early alerting.

AbstractInspired from helical structures in nature, liquid crystal elastomer (LCE) fiber actuators are developed for soft robotics and smart wearables. However, the facile development of robust LCE yarn actuators remains challenging due to the lightly cross‐linked networks of LCE with the inherently poor mechanical properties. Here, the bionic helical yarn actuator is constructed through integrating the shape‐morphing LCE fiber as the actuation phase and the highly ordered orientation biomass bacterial cellulose (BC) macrofibers as the reinforcement phase by a facile twisting and two‐step cross‐linking strategy. Thanks to the 3D nanofiber network inside BC macrofibers and biomimetic helical structure, the mechanical strength (43.9 MPa) and the creep phenomenon of the resulted yarn have been significantly improved, which are obviously better than the reported LCE fiber actuators (1.4–30.8 MPa). The designed LCE/BC helical yarn actuators demonstrate high work capacity (304.1 J kg−1) and reliable reusability. As a proof‐of‐concept, this work constructs micro rolling device with customizable speed, soft gripper for grasping and moving heavy objects and passive micro motor with a speed of 7.7 rad s−1. The findings of this work are expected to provide insights into the development of high‐performance and durable smart yarn actuators through biomimetic engineering strategies.

Published: February 2025

AbstractThe interactions between supramolecular nanofibers and proteins are crucial for functional biomaterials while there is lack of direct method to interpret supramolecular nanofiber‐protein interactions. In parallel to the single‐component system, here it is demonstrated that the deconvolution of time‐resolved photoluminescence (PL) is valid to depict the dynamic self‐assembly process of two‐component systems including co‐assembly and nanofiber‐protein complexes. For a model assembling tetrapeptide FFKY, the effects on the fluorescence lifetime of its fluorescent hydrogelator co‐assembling with a non‐fluorescent derivative allowed to quantify the assembly parameters of non‐fluorescent hydrogelators. Additionally, this method is readily extended to determine the assembly parameters of a disease‐related amyloid core sequence KLVFF. Finally, this method is used to monitor the nanofiber‐protein complexes. The changes in the self‐assembly process indicated the selective interaction between supramolecular nanofiber and specific proteins. Overall, the time‐resolved PL served as an adequate methodology for the investigation of nanofiber‐protein interactions in vitro under highly dynamic and non‐equilibrated conditions.

AbstractThe development of platinum group metal‐free catalysts for the oxygen reduction reaction (ORR) is critical to advancing sustainable energy conversion technologies. Manganese (Mn)‐based catalysts, known for their reduced toxicity and promising durability, have traditionally exhibited lower ORR activity compared to state‐of‐the‐art iron‐nitrogen‐carbon (Fe‐N‐C) catalysts. In this study, a highly efficient Mn‐N‐C‐S catalyst is presented, engineered through a sulfur‐mediated high‐shell coordinated doping strategy, that markedly enhances ORR activity and stability. The Mn‐N‐C‐S catalyst achieves a record‐high half‐wave potential of 0.94 V in alkaline media, among the highest values reported for Mn‐based catalysts. Additionally, in acidic media, it exhibits a half‐wave potential of 0.80 V, placing it among the top‐performing M‐N‐C catalysts. The catalyst also demonstrates a high peak power density of 0.82 W cm−2 in H2‐O2 fuel cells and 0.264 W cm−2 in Zn‐air batteries, outperforming previously reported Mn‐based catalysts. Both experimental findings and theoretical computations suggest that the high‐shell S‐doping can increase the spin density of Mn sites, strengthen Mn‐N bonds, and thereby improve the durability of Mn‐N4 sites. This work underscores the effectiveness of high‐shell sulfur doping and paving the way for their deployment in the cathodes of fuel cells and metal‐air batteries.

AbstractAs an emerging photovoltaic material, antimony selenosulfide (Sb2(S,Se)3) has attracted considerable attention and research enthusiasm. However, the current solution‐processed Sb2(S,Se)3 layers suffer from severe unfavorable energy band structure problems attributed to the vertical gradient‐variable Se/S atomic ratio, making it a challenging and prospective subject. Herein, a novel and convenient alkali metal Cs+‐induced Se/S atomic ratio variation strategy has been developed for the first time to regulate Sb2(S,Se)3 energy band structure through hydrothermal‐processed CdS nanorod‐arrays (NAs)/Sb2(S,Se)3 bulk heterojunction (BHJ) films. The Cs+‐induced regulation strategy narrows Se‐elemental concentration gradient distribution adjusting effectively Se/S atomic ratio in longitudinal CdS‐NAs/Sb2(S,Se)3 BHJ films. This generates a favorable energy band structure, contributing to rapid charge separation and extraction of photogenerated carriers of CdS‐NAs/Sb2(S,Se)3 BHJ. Meanwhile, the Cs+‐induced Se/S ratio variation not only passivates the defect‐state concentration and enhances crystal size of CdS‐NAs/Sb2(S,Se)3 film, bust also extend the carrier lifetime for Sb2(S,Se)3 BHJ photovoltaic devices. The resulting Cs‐Sb2(S,Se)3 BHJ photovoltaic devices exhibit an impressing power conversion efficiency (η) of 8.23%, the highest one currently available for Sb2(S,Se)3 BHJ solar cells. This study will undoubtedly facilitate the development of efficient Sb2(S,Se)3 BHJ devices, and other similar inorganic semiconductor photovoltaic devices.

AbstractMetal halide perovskite nanocrystals (PeNCs) have emerged as promising materials for next‐generation light‐emitting diodes (PeLEDs) due to their outstanding optical properties. However, synthesis challenges such as rapid crystallization often introduce defects that degrade device performance. Herein, a dual‐ligand approach employing trioctylphosphine oxide (TOPO) and phenylphosphinic acid (PPIA) is introduced to coordinate Pb2⁺ ions, effectively slowing the crystallization process and minimizing defect formation. The obtained PeNCs exhibit a high photoluminescence quantum yield (PL QY) of 93%. Additionally, the PPIA ligand enhances electrical conductivity via π‐electron resonance, enabling more efficient charge transport in FAPbBr3 films. As a result, the optimized PeLEDs achieve a peak external quantum efficiency (EQE) of 24.2% and a luminance of 32 840 cd m−2, significantly outperforming the control devices, which exhibit an EQE of 12.1% and a luminance of 1577 cd m−2. Furthermore, the operational lifetime of the optimized PeLEDs is 5.3 times longer than that of the control devices. These findings offer a promising pathway for advancing the performance and stability of PeLEDs.

AbstractThe continuous advancement of electronic devices, driven by trends toward miniaturization, reduced weight, higher integration, and multifunctionality, imposes stringent requirements on the performance of electromagnetic wave (EMW) absorbing materials. Traditional EMW absorbers, such as metals, face significant drawbacks, including high density and rigidity, which limit their broader application in EMW absorption. To overcome these issues, cellulose is employed as the matrix, incorporating nickel ferrite (NiFe2O4) nanocrystals and carbon nanotubes (CNTs) as functional fillers. The ferrite/CNT/cellulose aerogels (NCCAs) are fabricated through ionic crosslinking and room‐temperature drying techniques. The results show that the porous structure of NCCA enhances multiple scattering and energy dissipation pathways for EMWs, while CNTs provide excellent electrical dissipation. The content of NiFe2O4 nanocrystals strongly influences the aerogel's saturation magnetization and the electromagnetic parameters of the NCCAs, primarily owing to their superior dielectric and magnetic loss properties. Notably, when the content of NiFe2O4 nanocrystals is 4% of the cellulose mass, the NCCA achieves the lowest reflection loss of −66.53 dB at 16.11 GHz, and lower than most reported ferrite‐based EMW absorbers. This work provides valuable insights and guidance for the design of novel aerogel‐based EMW absorbers with lightweight properties, strong absorption intensities, and broad absorption frequency bands.
Image Traceable Privacy Protection Scheme Based on Blockchain and Homomorphic Encryption
Authors: Li Tian , Zhang Qiu‐Yu , Wu Guo‐Rui 
Published: February 2025

ABSTRACTIn the blockchain environment, applications involving image sharing and transmission encounter challenges related to security, encryption efficiency, robustness, and susceptibility to image tampering and misuse. To address these concerns, we propose a privacy protection scheme for image traceability that leverages blockchain technology alongside homomorphic encryption. Initially, images are encrypted using homomorphic techniques combined with block technology. Subsequently, feature extraction is performed through Lifting Wavelet Transform (LWT) and Singular Value Decomposition (SVD), while provenance information is losslessly embedded into a zero‐watermark image generated via dynamic S‐boxes. Upon uploading to the blockchain, smart contracts and the Interplanetary File System (IPFS) are employed to regulate the transaction of images for enhanced traceability. Finally, a smart contract is utilized to detect any potential tampering of the images. Experimental results indicate that this scheme facilitates efficient distribution and computation of private data in ciphertext form during encryption/decryption operations. The zero‐watermarking algorithm demonstrates robust anti‐attack capabilities as well as resilience against various threats, effectively addressing both tamper detection and traceability issues for encrypted images while ensuring privacy protection during secure storage.

ABSTRACTIn this study, the effect of microwave treatment time (0, 30, 60, 90, and 120 seconds) on the physicochemical and functional properties of buckwheat (Fagopyrum esculentum L.) starch (containing 30% moisture content) isolated using the alkaline extraction method was investigated. X‐ray diffractometry and Fourier transform infrared absorbance ratio of 1047/1022 cm−1 showed that microwaves cleave and disrupt the amylopectin molecules, resulting in a less ordered structure and relative crystallinity in buckwheat starch. Apparent amylose content, water absorption capacity, and color values (a* and b*) increased significantly (p ≤ 0.05), whereas oil absorption capacity, light transmittance, swelling power, solubility index, syneresis, color value (L*), and whitening index reduced with increasing the treatment time (p ≤ 0.05). Microwave treatment also reduced buckwheat starch's pasting properties (peak, trough, breakdown, and final viscosities).

AbstractThe incorporation of recycled aggregates (RA) into ultra‐high‐performance concrete (UHPC) for sustainable construction offers a compelling solution for recycling waste construction materials while meeting high‐performance requirements. As a newly developed construction material, UHPC lacks performance data related to temperature. To address this knowledge gap, this study investigates the effect of high‐temperature exposure on the performance of UHPC incorporating recycled aggregates (RA) and steel fibers (SF). Five exposure temperatures (25, 200, 400, 600, and 800°C) were selected to simulate thermal conditions associated with structural fire scenarios. Specimens were prepared with five different mix proportions, varying the RA replacement rates (0%, 25%, 50%, 75%, and 100%) and SF content (0%, 1%, 1.5%, and 2%). After thermal exposure, a series of tests were conducted to evaluate physical properties (density, porosity, and color changes) and mechanical properties (compressive strength and stress–strain behavior). Additionally, X‐ray diffraction was used to analyze microstructural changes, detecting phase transformations and thermal decomposition products. The results indicate that the temperature has a significant impact on both physical and mechanical properties. As the temperature rises, apparent density decreases, porosity increases, and color changes provide visual cues for estimating fire temperatures. Compressive strength initially rises, peaking at 400°C with a 10%–30% enhancement, but declines sharply beyond this threshold. Higher SF content and lower RA replacement rates mitigate mechanical degradation, with optimal performance observed at 300°C and 2% SF content. X‐ray diffraction analysis reveals that the microstructure deteriorates progressively with increasing temperature, as phase transformations and microcracks reduce material density. A predictive model for the stress–strain relationship at high temperatures is proposed, considering the combined effects of temperature, RA content, and SF inclusions. This study provides critical insights into the thermal performance of UHPC with RA, offering a scientific foundation for practical engineering applications in fire‐resistant structures.
