Here, we developed core–shell nanocapsules composed of a cationized lactoferrin core and an alendronate polymer shell. By tuning the size of these nanocapsules and leveraging the alendronate shell, we enabled precise delivery of small interfering RNA targeting the Semaphorin 4D gene (siSema4D) to specific bone sites. This strategy integrates the antiresorptive drug alendronate with siSema4D, efficiently inhibiting osteoclast (OC) differentiation and bone resorption, while promoting osteogenesis to restore the balance between osteoblasts (OBs) and OCs. Moreover, encapsulating siSema4D within the nanocapsules helps to mitigate immunological cascades, thereby reversing the inflammatory microenvironment and restoring immune homeostasis and providing insights into the immunomodulatory effects of Sema4D in osteoporosis therapy. In both ovariectomized and senile osteoporotic mouse models, local intramuscular administration of core–shell nanocapsules effectively rectified the imbalance between the skeletal and immune systems, significantly enhancing the overall efficacy of osteoporosis treatment. Our findings underscore the therapeutic promise of addressing the multifaceted osteoporotic microenvironment through targeted interventions.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"27 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the Fe 3d and O 2p orbital hybridization was optimized by controlling the content of amorphous NiFe(OH)x (a-NiFe(OH)x), which was grown in situ on crystalline NiFe2O4 (c-NiFe2O4) using an ultrasonic reduction method. The results of electron energy loss spectroscopy (EELS) and X-ray absorption spectra (XAS) revealed that the Fe–Oa orbital hybridization in a-NiFe(OH)x is effectively strengthened by jointing with the adjacent oxygen (Oc) in c-NiFe2O4, which is further confirmed by the higher antibonding orbital energies based on density functional theory (DFT) calculations. The resultant Oa–Fe–Oc at the composite interface leads to balanced adsorption and desorption energies. Accordingly, the optimal composite with strong Fe 3d-O 2p hybridization results in enhanced OER performance, and the overpotential is 150 mV, lower than that of the pristine sample. This work represents a promising approach to orbital hybridization via the introduction of an amorphous phase to construct highly efficient catalysts.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"16 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermally regenerative electrochemical cycle (TREC) is a promising approach for low-grade heat harvesting with high energy conversion efficiency. Here, we achieved co-optimization of temperature coefficient (−3.96 mV K−1), specific charge capacity (theoretical, 97.36 Ah L−1) and specific heat capacity in TREC by applying a thermosensitive slurry electrolyte system, in which Fe(CN)64−-based thermosensitive crystallization were incorporated into the Fe(CN)63−/4− solution. We demonstrated an electrically assisted TREC system with Fe(CN)63−/4− catholyte and an Ag/AgCl anode, and a charging-free TREC system with Fe(CN)63−/4− catholyte and I3−/I− anolyte. Both two systems perform high absolute heat-to-electricity energy conversion efficiency of 4.42% and 2.51%, respectively, in the absence of heat recuperation. This study provides a general approach of electrolyte design aimed at enhancing temperature coefficient and specific charge capacity, while simultaneously optimizing specific heat capacity, thereby facilitating the development of more efficient TREC systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"35 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite many works concentrating on the A- and X-site mixing effects, a comprehensive study on the effects of B-site mixing on the structural and dynamic properties of MA-based perovskites is still absent. In this work, we investigate the structural and dynamic properties of mixed lead–tin halide perovskites MAPb1–xSnxBr3 using a multitechnique experimental approach including differential scanning calorimetry, dielectric spectroscopy, and nuclear quadrupole resonance experiments. We map the phase diagram of this system, which reveals that B-site mixing slightly stabilizes the cubic phase and affects the MA cation dynamics and ordering, although the observed effects are less prominent compared with A- and X-site mixing. Our results provide insights into the complex interplay of structural and dynamic properties in mixed-metal perovskites contributing to their potential optimization for photovoltaic applications.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"52 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PFAS have caused potential risks because of their persistence and bioaccumulation, consequently causing possible harm to human health and ecosystems. The fabrication of novel sensing technologies represents the game-changing strategy that can address current limitations of the conventional chromatographic techniques. This review highlights cutting-edge improvements in PFAS nano-sensor engineering, emphasizing molecular chemistry advancements in optical, electrochemical, aptamer-based, and immune-based nanosensors. Insights into tried-and-tested tactics by receiving an in-depth examination of each nano-sensor's detecting approach at the molecular level are elucidated. Potential mechanisms of interaction between PFAS and emerging nanomaterials are presented, encompassing fluorophilic interactions, electrostatic interactions, ion-bridging interactions with divalent cations, hydrophobic interactions, π-π bonds, hydrogen bonds, ionic exchange, and Van der Waals forces, in conjunction with materials such as single-atom supported nanomaterials, carbon dots, graphene, and metallic nanostructures. Using an integrated approach, the review explores current difficulties and potential in PFAS nano-sensor manufacture. Notably, it describes critical sensor development objectives and goes into what challenges were experienced during the process, thus facilitating the transfer of the most promising nano-sensor technologies into the industrial practice.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"23 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nano-state interfacial products Mg2Si and MgO adhered to the SiC surface, facilitating load transfer. The Al4C3 and Mg₃₂(Al,Zn)₄₉ are present near SiC, the brittleness of Al4C3 reduces the composite plasticity. After adding 1 wt.% SiC, the yield strength (YS), ultimate tensile strength (UTS) and elongation (El) of AZ91 alloy increased to 250 MPa, 350 MPa and 15.1%, respectively.
