AbstractTriboelectric nanogenerators (TENGs) have gained significant attention for ability to convert mechanical energy into electrical energy. As the applications of TENG devices expand, their safety and reliability becomes priority, particularly where there is risk of fire or spontaneous combustion. Flame‐retardant materials can be employed to address these safety concerns without compromising the performance and efficiency of TENGs. The primary focus of this review is on flame‐retardant materials, including polymers, biomaterials, liquid polymers, aerogels, and carbon‐based materials. The fundamental properties of these materials for TENG applications are elucidated. The characteristics of each material type are described, along with their potential to boost the safety and performance of TENGs. The importance of flame retardancy in advancing TENG technology can be projected from its usage in wearable electronics, self‐powered sensors, and smart textiles. Current challenges such as material compatibility, fabrication complexity, and environmental concerns are addressed, along with proposed strategies for overcoming them. This review underscores the significance of flame‐retardant materials in strengthening the functionality and safety of TENG devices, paving the way for their widespread adoption across various industries.

AbstractStructural diversity of biomolecules leads to various supramolecular organizations and asymmetric architectures of self‐assemblies with significant piezoelectric response. However, the piezoelectricity of biomolecular self‐assemblies has not been fully explored and the relationship between supramolecular structures and piezoelectricity remains poorly understood, which hinders the development of piezoelectric biomaterials. Herein, for the first time, the piezoelectricity of vitamin‐based self‐assemblies for power generation is systematically explored. X‐ray diffraction studies revealed that vitamin molecules can self‐assemble into different supramolecular structures, which exhibited tunable piezoelectric coefficients ranging from 3.8 to 42.8 pC N−1 by density functional theory (DFT) calculations. Notably, vitamin B7 D‐biotin (D‐BIO) self‐assemblies exhibited superior piezoelectricity due to low crystal symmetry and high polarization of supramolecular arrangements. The D‐BIO assemblies‐based piezoelectric nanogenerator (PENG) produced output voltages of ≈0.8 V under a mechanical force of 47 N, showing high mechanical durability after 5400 pressing‐releasing cycles and high stability of at least three months. The PENG‐based wearable sensor successfully detected bending motions of human limbs. Furthermore, the PENG‐based insole converted biomechanical energy into stable electrical energy upon foot movement, illuminating 12 light‐emitting diodes (LEDs). This work fills knowledge gaps in piezoelectricity of vitamin‐based self‐assemblies, providing paradigms for realizing high‐performance piezoelectric biomaterials through supramolecular engineering.

AbstractMechanical information is a medium for perceptual interaction and health monitoring of organisms or intelligent mechanical equipment, including force, vibration, sound, and flow. Researchers are increasingly deploying mechanical information recognition technologies (MIRT) that integrate information acquisition, pre‐processing, and processing functions and are expected to enable advanced applications. However, this also poses significant challenges to information acquisition performance and information processing efficiency. The novel and exciting mechanosensory systems of organisms in nature have inspired us to develop superior mechanical information bionic recognition technologies (MIBRT) based on novel bionic materials, structures, and devices to address these challenges. Herein, first bionic strategies for information pre‐processing are presented and their importance for high‐performance information acquisition is highlighted. Subsequently, design strategies and considerations for high‐performance sensors inspired by mechanoreceptors of organisms are described. Then, the design concepts of the neuromorphic devices are summarized in order to replicate the information processing functions of a biological nervous system. Additionally, the ability of MIBRT is investigated to recognize basic mechanical information. Furthermore, further potential applications of MIBRT in intelligent robots, healthcare, and virtual reality are explored with a view to solve a range of complex tasks. Finally, potential future challenges and opportunities for MIBRT are identified from multiple perspectives.

AbstractAnode‐free sodium batteries (AFSBs) hold great promise for high‐density energy storage. However, high‐voltage AFSBs, especially those can stably cycle at a wide temperature range are challenging due to the poor electrolyte compatibility toward both the cathode and anode. Herein, high‐voltage AFSBs with cycling ability in a wide temperature range (−20–60 °C) are realized for the first time via a sole‐solvent high‐entropy electrolyte based on the diethylene glycol dibutyl ether solvent (D2) and NaPF6 salt. The sole‐solvent high‐entropy electrolyte with unique solvent‐ions effect of strong anion interaction and weak cation solvation enables entropy‐driven electrolyte salt disassociation and high‐concentration contact ion pairs, thus simultaneously forming stable anion‐derived electrode–electrolyte interphases on cathode and anode. Moreover, the wide liquid range of D2 further extends the temperature extremes of the battery. Consequently, ampere‐hour (Ah)‐level anode‐free sodium pouch cells with cyclability in a wide temperature range of −20–60 °C are realized. Impressively, the pouch cell achieves a leadingly high cell‐level energy density of 209 Wh kg−1 and a high capacity retention of 83.1% after 100 cycles at 25 °C. This work provides inspirations for designing advanced electrolytes for practical AFSBs.

Published: January 2025

AbstractA base‐mediated one‐pot, two‐step, four‐component reaction has been developed to synthesize imidazole‐4(2H)‐ones, utilizing commercially available amino acid esters, aldehydes, alkynes, and amino alcohols. Control experiments and isolation of the intermediate revealed the mechanistic details. This four‐component reaction proceeds via imine formation, followed by the nucleophilic addition of alkyne to form a propargylamine precursor. Subsequently, the propargylamine precursor under undergoes base‐mediated conversion into 1‐azadiene, followed by in situ ketene formation to generate (allylideneamino)prop‐1‐en‐1‐one. The nucleophilic addition of amino alcohol and subsequent intramolecular cyclization provides imidazole‐4 (2H)‐ones exclusively.

Published: January 2025

AbstractAn electrochemical protocol for the alkylation of imines was developed by using easily available alkyl halides as the alkyl sources, graphite felt (GF) as anode and zinc plate as cathode. Various substituted imines, alkyl bromides and alkyl iodides were suitable for this reaction and a series of α‐branched amines were obtained in moderate to good yields. This method provides a green way for the addition of imines to avoid the need for metal reagents, chemical oxidants and reductants, which makes it has a good application prospect in drug synthesis.

Published: January 2025

AbstractIsomer discrimination is of paramount importance across various sectors, including pharmaceuticals, agriculture, and the food industry, owing to their unique physicochemical characteristics. Because of their extremely similar characteristics, traditional analytical methods fail or encounter severe limitations in isomer discrimination. To overcome this grand challenge, a novel sensing strategy is proposed based on surface‐enhanced Raman scattering (SERS) substrates (i.e., plasmonic platforms) combined with machine learning algorithms. These plasmonic platforms exhibit exceptional signal uniformity across wide regions and sensitivity, enabling the discrimination of structural isomers (hydroquinone, resorcinol, pyrocatechol), geometric isomers ((Z/E)‐stilbene, (Z/E)‐resveratrol), and optical isomers (R/S‐ibuprofen). Notably, for the analysis of optical isomers, 1‐naphthalenethiol is employed as a probe to facilitate specific isomer orientation on the surface of the plasmonic platform through, for the first time, π–π interactions. The integration of machine learning methodologies, such as Partial Least Squares Regression and Artificial Neural Networks, significantly enhances both quantitative analysis and classification accuracy, achieving detection limits as low as 2 × 10⁻⁸ m. Validation with commercially available ibuprofen samples shows excellent agreement with traditional circular dichroism results, highlighting the method's robustness and precision. The strategy provides a versatile, ultrasensitive, and reliable solution for isomer discrimination, with broad applications in pharmaceuticals, environmental monitoring, and clinical diagnostics.

AbstractRheumatoid arthritis (RA) is a common chronic systemic autoimmune disease that often results in irreversible joint erosion and disability. Methotrexate (MTX) is the first‐line drug against RA, but the significant side effects of long‐term administration limit its use. Therefore, new therapeutic strategies are needed for treating RA. Here, dual‐targeting biomimetic carrier‐free nanomaterials (BSA‐MTX‐CyI nanosystem, BMC) is developed for synergistic photo‐chemotherapy of RA. Bovine serum albumin (BSA), which has high affinity with SPARC (secreted protein acidic and rich in cysteine) in the RA joint microenvironment, is selected as the hydrophilic end and coupled with MTX and the phototherapeutic agent CyI to self‐assemble into BMC. In vitro and in vivo experiments revealed that BMC accumulated significantly at the joint site in collagen antibody‐induced arthritis mice and could be specifically recognized and taken up by folate receptors in proinflammatory M1 macrophages. Upon near‐infrared laser irradiation, CyI exerted photodynamic and photothermal effects, whereas MTX not only inhibited cell proliferation but also increased cell sensitivity to reactive oxygen species, enhancing the apoptotic effect induced by CyI and achieving synergistic photo‐chemotherapy. Moreover, BMC could induce macrophages to reprogram into anti‐inflammatory M2 macrophages. This study provides innovative approaches for RA treatment via macrophage apoptosis and re‐polarization.

AbstractPhotothermal catalysis, a frontier in heterogeneous catalysis, combines light‐driven and thermally enhanced chemical reactions to optimize energy use and reaction efficiencies at catalytic active sites. By leveraging photothermal conversion, this approach links renewable energy sources with industrial chemical processes, offering significant potential for sustainable applications. This review categorizes photothermal catalysis into three types: light‐driven thermocatalysis, thermally enhanced photocatalysis, and photo‐thermo coupling catalysis. Each category is analyzed, emphasizing mechanisms, performance factors, and the role of advanced materials such as plasmonic nanoparticles, semiconductors, and hybrid composites in enhancing light absorption, thermal distribution, and catalytic stability. Key challenges include achieving uniform thermal and photonic energy distributions within catalytic reactors and developing accurate performance evaluation metrics. Applications such as CO₂ reduction, ammonia synthesis, and plastic upcycling highlight the environmental and industrial relevance of this technology. The review identifies limitations and suggests innovations in materials design and energy‐storing mechanisms to enable continuous catalytic processes. Future directions emphasize photothermal catalysis's potential to transform sustainable energy systems and advance green chemical production. This synthesis aims to guide research and foster practical adoption of photothermal technologies at an industrial scale.
Staging an Experience of Cultural Heritage Preservation: Consumers' Willingness to Pay for Heirloom Rice in the Philippines
Authors: Britwum Kofi , Demont Matty 
Published: January 2025

ABSTRACTThe Cordillera Administrative Region in the Philippines is home to terraced rice embedded in centuries of cultural heritage. However, weak market incentives threaten sustained production, jeopardizing indigenous communities' cultural heritage and the in situ biodiversity of rice genetic resources. Demand‐side policy interventions have been proposed to address these challenges. Drawing on the experience economy, we staged an experience with urban consumers, offering them the opportunity to participate in cultural heritage preservation through purchasing heirloom rice. Participants first self‐selected into white or brown rice market segments as a benchmark. Subsequently, each market segment was invited to (i) identify their preference between their benchmark and heirloom rice, and (ii) bid to upgrade their non‐preferred to their preferred rice through a Becker‐DeGroot‐Marschak (BDM) mechanism. The sample was randomly split between a control group and two “experience treatment” groups exposed to gain‐ or loss‐framed narratives about rice terrace preservation. Results reveal that a subset of consumers in each market segment switched to heirloom rice. White rice consumers were more reluctant to transition to heirloom rice, although they responded positively to the gain‐framed narrative, paying the highest price premiums for heirloom rice (PhP 92.55 or US $2.03 per kilogram). Brown rice consumers were more willing to switch but willing to pay lower premiums for heirloom rice, altogether suggesting the need for a segmented marketing strategy. Highlighting nutritional benefits and quality is crucial, but positioning heirloom rice within a gastronomic system that showcases its use in specific dishes and occasions is equally important for enhancing consumer appeal.

ABSTRACTEfficient photosensitizers are crucial for the success of photodynamic therapy (PDT). Herein, we reported two [3+2+1] coordinated organometallic Iridium (III) complexes (labeled as Ir‐C1 and Ir‐C4). Ir‐C1/C4 can generate both type I and type II reactive oxygen species (ROS). In vitro experiments, Ir‐C1/C4 show low biotoxicity and high phototoxicity of half‐maximal inhibitory concentration values of 14 nM and 33 nM on rectal cancer cell line HCT116, respectively. Western blot analysis revealed that the Ir‐C1/C4 activated ferroptosis, apoptosis, and inhibiting autophagy simultaneously. Proteomics analysis demonstrated that the photosensitizers destroyed the endoplasmic reticulum (ER), blocking the signal transmission and material transfer between the ER and other tissues of the cell, especially the ER to Golgi vesicle‐mediated transport. Ir‐C1/C4 can achieve better antitumor performance than commercial photosensitizer Chlorin e6 and the ferroptosis activator RSL3 at lower concentrations. The low biotoxicity and high phototoxicity make them ideal candidates for PDT. The findings provide new insights into the design of photosensitizers for metal complexes and have significant implications for the development of PDT and related drugs.

AbstractPhotodynamic therapy (PDT) has emerged as a promising targeted treatment for cancer. However, current PDT is limited by low tissue penetration, insufficient phototoxicity (toxicity with light irradiation), and undesirable cytotoxicity (toxicity without light irradiation). Here, we report the discovery of cyanine‐carborane salts as potent photosensitizers (PSs) that harness the near‐infrared (NIR) absorbing [cyanine+] with the inertness of [carborane−]. The implementation of [cyanine+] [carborane−] salts dramatically enhance cancer targeting of the PSs and decrease cytotoxicity. We characterize the cellular uptake of the cyanine‐carborane PSs, organelle localization, generation of reactive oxygen species (ROS) with the ability to cogenerate multiple ROS species, suppression of pro‐metastatic pathways, and activation of apoptotic pathways. We further demonstrate the ability of optimized PSs to eliminate tumors in vivo using an orthotopic mouse model of breast cancer. These newly developed [cyanine+] [carborane−] salt PSs introduce a potent therapeutic approach against aggressive breast cancer while decreasing side effects.

AbstractUnderstanding the chemistry of the inert actinide oxo bond in actinyl ions AnO22+ is important for controlling actinide behavior in the environment, during separations, and in nuclear waste (An=U, Np, Pu). The thioether calixarene TC4A (4‐tert‐butyltetrathiacalix[4]arene) binds equatorially to the actinyl cation forming a conical pocket that differentiates the two trans‐oxo groups. The ‘ate’ complexes, [A]2[UO2(TC4A)] (A=[Li(DME)2], HNEt3) and [HNEt3]2[AnO2(TC4A)] (An=U, Np, Pu), enable selective oxo chemistry. Silylation of the UVI oxo groups by bis(trimethylsilyl)pyrazine occurs first at only the unencapsulated exo oxo and only one silylation is needed to enable migration of the endo oxo out of the cone, whereupon a second silylation affords the stable UIV cis‐bis(siloxide) [A]2[U(OSiMe3)2(TC4A)]. Calculations confirm that only one silylation event is needed to initiate oxo rearrangement, and that the putative cis dioxo isomer of [UO2(TC4A)]2− would be stable if it could be accessed synthetically, at only 23 kcal.mol−1 in energy above the classical trans dioxo. Calculations for the transuranic cis[AnO2(TC4A)]2− (An=Np, Pu) are at higher energies, 30–35 kcal.mol−1, retaining the U complexes as the more obvious target for a cis‐dioxo actinyl ion. The aryloxide (OAr) groups of the macrocycle are essential in stabilizing this as‐yet unseen uranyl geometry as further bonding in the TC4A U‐OAr groups stabilizes the U=O ‘yl’ bonds, explaining the stability of the putative cis[UO2(TC4A)]2− in this ligand framework.

AbstractThe synthesis of metal–organic frameworks (MOFs) with diverse geometries has captivated considerable interest due to their manifestation of novel and extraordinary properties. While much progress has been made in shaping regular polyhedral single‐crystal MOFs, the creation of more complex, topologically intricate nanostructures remains a largely unexplored frontier. Here, we present a refined site‐specific anisotropic assembly and etching co‐mediation approach to fabricate a series of hierarchical MOF nanohybrids and single‐crystal MOFs. This approach yields ZIF‐8&mSiO2 nanohybrids with diverse topologies, alongside derived single‐crystal MOF nanoparticles exhibiting intricate morphologies such as hexapods, nested nanocages, and octopods. Our method involves the selective growth of six mSiO2 nanoplates on the {100} facets of ZIF‐8 nanocubes, forming the cubic‐shaped ZIF‐8&mSiO2 nanohybrids, with the concurrent etching of the {110} facets of initial ZIF‐8 nanocubes. By fine‐tuning this balance between the growth and etching, we achieved precise morphological control, transforming cubic nanohybrids into intricate hexapods nanohybrids. Additionally, secondary epitaxial growth of homo‐ or hetero‐MOFs on these hybrids led to ZIF‐8&mSiO2&MOF composites with six mSiO2 inlays. Finally, selective alkaline etching of the mSiO2 compartments result in single‐crystal MOF nanoparticles with unprecedented and sophisticated morphologies, such as hexapods, nested nanocages, octopods. This work advances the field of MOF nanostructure design, opening new avenues for the development of sophisticated, multifunctional materials.
