Herein, tailored hydrophobic metal-organic frameworks (MOFs) are employed as interfacial layers between perovskite absorbers and hole transport layers (HTLs). The tailored MOFs feature abundant carboxylic acid groups capable of bonding with Pb<sup>2+</sup> and organic cations, which can effectively passivate interface defects and suppress non-radiative recombination. Meanwhile, the MOF interfacial layers optimized the energy level alignment between the perovskite and the HTL, further facilitating carrier transportation. Specifically, the CsFAMA-based PSCs with a bandgap of 1.63 eV attained power conversion efficiency (PCE) of 23.06% upon modification with MOFs. Additionally, the MOFs-treated FA-based PSCs with a bandgap of 1.55 eV achieved a remarkable PCE of 24.81%, accompanied by an outstanding fill factor of 84.3% and a minimal open-circuit voltage loss of merely 0.386 V. Furthermore, the integration of the MOF interfacial layer substantially improved the moisture stability of the PSCs. The unencapsulated CsFAMA PSCs modified with MOFs retained 91.2% of their initial efficiency after 2500 h of aging under ambient conditions with 40% relative humidity (RH). This work underpins the commercialization of PSCs with diverse bandgaps.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"193 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678860","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}

In autoimmune diseases like rheumatoid arthritis (RA), targeted mRNA delivery provides a potential intervention to modulate immune responses. However, achieving specific and efficient in vivo modulation of immune regulators, such as the inhibitory Fc gamma receptor, FcγRIIB, on B cells remains challenging. In this study, lipid polymer nanoparticles (LPNs) formulated with AMB-POC18 lipidoid and poly(ethylene glycol)-<i>block</i>-polylactide (PEG-PLA) are engineered to deliver FcγRIIB mRNA (mFcγRIIB) specifically to splenic B cells for RA treatment. Protein corona analysis indicated that selective adsorption of complement C3 on the LPNs' surface facilitated their targeted delivery to the spleen, enhancing transfection efficiency in B cells following intravenous administration. In a collagen-induced arthritis mouse model, mFcγRIIB/LPNs effectively upregulated FcγRIIB expression in splenic B cells, significantly reducing autoimmune responses and alleviating RA symptoms. Further mechanistic studies elucidated that increased FcγRIIB expression suppressed B cell activation via the FcγRIIB/Lyn/SHP-1 signaling pathway. This work underscored the potential of the spleen-targeted mRNA delivery system for RA therapy, providing a precise and targeted approach to modulate B cell activity and mitigate autoimmune diseases.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"12 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673686","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}

This is due to the involvement of macromolecules that control biomineralization. Even though the interactions of these biopolymers with solid mineral phases are intensely studied, not much is known about their involvement in the preceding steps of intracellular transport of the mineral building blocks. In this work, the model system of coccolith calcite crystallization is utilized to address the role of mineral-associated polysaccharides in the transport of calcium ions. State-of-the-art cryo-electron tomography is used to image in situ ion-rich dense phases in the wild-type and in two mutant strains, defected in coccolith production. The results show that the abundance and solubility of the calcium-rich condensates need to be finely tuned for proper crystallization. When the native macromolecular assemblage is compromised, calcium is still present in the calcifying fluid as a solute, but this is not sufficient for coccolith development. These results suggest that biomineralizing systems achieve superior regulation of crystallization due to the use of dense macromolecule-rich phases.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"99 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678410","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}

By leveraging the high piezoelectric coefficient of PVDF-TrFE and the conductivity of PEDOT:PSS, the actuators exhibit stable performance with precise inkjet printing deposition and optimized waveform parameters. The fabrication process integrates inkjet printing and standard lithography, enabling monolithic integration for high-performance actuation and multifunctional sensing. The PVDF-TrFE-based actuators achieve low-voltage operation (as low as 50 V), efficient energy transfer, and mechanical stability. Enhancing the beta phase of PVDF-TrFE resulted in a deflection of ≈600 µm and vortex generation, crucial for lift in aerial robotic applications. Durability tests confirmed minimal performance degradation after 2,300 actuation cycles. Beyond mechanical deflection, the actuators exhibit sound detection and strain sensing capabilities. Experimental evaluations validated their ability to differentiate sound frequencies, detect muscle strain, and replicate bio-inspired flight dynamics. A preliminary proof of concept for a double-wing structure demonstrated lift generation at low voltages and resonant frequencies. The results indicate that these piezoelectric actuators are well-suited for miniaturized robotic applications, particularly in aerial locomotion and multifunctional sensing, opening new possibilities for innovations in micro-robotics, wearables, and aerial robotics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"22 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678414","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}
