The continuous growth and the risk of rupture of AAAs threaten patients' health. Despite positive outcomes in preclinical studies, no pharmacological approach is proven effective in stabilizing and reversing the progression in the clinic. Insufficient local drug concentration, dynamic aorta environment, and unique anatomical characteristics attenuate the efficacy of systemic administration. To overcome the gap between laboratory and clinic, nanomedicine strategies are applied in a wide range of studies to optimize the in vivo behavior of the drugs. The emerging nano-delivery technologies are shown to have the potential to improve the efficacy of drugs against AAA through diverse mechanisms. Herein, the composition and characteristics of the AAA environment are summarized, followed by the review of multiple AAA-targeted nano-scale therapeutic strategies, which are classified according to the utilized AAA properties and the targeting mechanism. Additionally, the future of developing novel AAA therapeutic strategies is being envisioned and discussed. These technologies are expected to be the last piece of the puzzle to solve the lack of effective pharmacological methods for treating AAA.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2402268"},"PeriodicalIF":10.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092440","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}

Herein, an angular deposition technique is employed to harness capillary and Marangoni flows to fabricate CNC photonic films with spatially tunable structural colors spanning from red to blue. A crucial relation between the substrate angle, the development of color zones, film coverage and film thickness is discovered. The color range of the photonic films can be shifted by tuning the size distribution of CNC particles is also demonstrated. As the CNC particles and tactoids are deposited on the substrate, a central deformation line emerged with tilted and folded domains, which is a consequence of Marangoni flow-induced deformation of the tactoids at the early stages of deposition. Further in the process, well-aligned domains emerged at the bottom of the substrates, indicating the simultaneous kinetic onset of multiple gelation processes which depend on size segregation across different color zones. Such insights allow us to tune the color domains using angular deposition and manipulate the kinetic arrest phase transition to produce more uniform and homogeneous films.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401966"},"PeriodicalIF":10.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092398","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}

Besides, the lower intensity associated to collective vibrational modes and their low frequency makes their study a demanding task. In this sense, nanographenes are promising materials that can be synthesized with tailored shapes and sizes-including edge substituents-, offering a great platform for studying collective vibrational modes. Here, femtosecond impulsive vibrational spectroscopy, Raman spectroscopy, and density functional theory calculations are combined to investigate for the first time low-frequency vibrational motions in two dibenzo[hi,st]ovalene (DBOV) nanographenes. The systematic study of mesityl-substituted DBOV (DBOV-Mes) and its chloro-functionalized derivative (Cl-DBOV-Mes) demonstrates that collective vibrational modes supported by DBOV derivatives can be altered with edge substitution, while optoelectronic properties are preserved.

Incorporating transition metal (TM) into phosphorus to form TM phosphides and combining them with low-dimension materials represents effective strategy for enhancing the electrochemical performances. Herein, a 3D network FeP@MXene composite anode is proposed with exhibiting a high reversible capacity of 444.1 mAh g-1 at current density of 500 mA g-1 after 500 cycles for lithium-ion batteries. The study reveals that the exceptional cycling stability originates from the synergistic combination of high specific surface area and a structural design buffering volume expansion. Specifically, Prussian blue (PB) derived cubic structures are uniformly dispersed within a 3D interwoven network of MXene nanosheets. Notably, the pseudocapacitive dominated fast lithium storage kinetics of this active material induces uniformly incomplete lithium intercalation during the initial cycles. This mechanism effectively circumvents the severe capacity decay observed in conventional metal phosphides, which arises from heterogeneous lithium intercalation induced severe volume fluctuations.

Neuroinflammation is a key factor affecting patient outcomes both acutely and chronically. Traditional diagnostic tools, such as computed tomography imaging and the Glasgow Coma Scale, are limited in detecting molecular changes, particularly related to neuroinflammation. Small extracellular vesicles (sEVs) are cell-specific vesicles that enable cell-to-cell communication and are involved in TBI pathology. In this study, brain-specific sEVs are isolated by targeting brain-associated markers, sodium/potassium-transporting ATPase subunit beta-2 (ATP1B2) and excitatory amino acid transporter 2 (EAAT2), and employed surface-enhanced Raman spectroscopy to profile inflammation-associated cytokine chemokine (C-C motif) ligand 2 (CCL2) bound to single sEV, allowing for blood-based monitoring of neuroinflammation. This approach enabled the direct assessment of neuroinflammation in both human TBI samples and a controlled cortical injury in a rat model. This study found elevated brain-specific sEVs with enhanced CCL2 in TBI samples compared to non-TBI cohorts. The results suggest that the TBI diagnostic platform can detect an increased level of brain-specific sEVs carrying neuroinflammatory signals in TBI clinical samples with high specificity and sensitivity, offering potential as a precise diagnostic tool for TBI diagnosis.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401931"},"PeriodicalIF":10.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092453","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 development of a robust, selective, as well as recyclable, non-noble catalyst that can be powered by visible light and uses water as proton source to accomplish this important reaction remains a key challenge. Here the first demonstration of a cobalt single-atom catalyst supported on carbon-nitride (Co-CN) as an all-in-one photocatalyst for the semi-hydrogenation of acetylene to ethylene is reported using water as the proton source, offering advantages over current hydrogenation technologies. Carbon nitride hosts the individual catalytic active sites of cobalt thus combining photosensitizer and cocatalyst in one unit, in line with first-principles modelling. Under visible light irradiation, Co-CN reduces acetylene to ethylene with stable activity for over 40 days of continuous operation, ≥99.9% selectivity, and provides means for coupling organic upgrading to produce valuable oxidation products. The heterogeneous Co-CN can be easily recovered and reused repeatedly without loss of catalytic activity and structural integrity. Thereby, the integrated and recyclable platform overcomes the need of coupling a separate photosensitizer to a catalyst, and using noble metal catalysts with an external H2 gas feed.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2500527"},"PeriodicalIF":10.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092447","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}

However, their commercialization is hindered by stability issues, such as ion migration, defect-induced degradation, and nonuniformity of the solution process over large areas, particularly at the perovskite/hole-transporting layer (HTL) interface. To address these challenges, chemical vapor deposition (CVD) is employed to introduce an ultrathin, uniform parylene-D layer at the perovskite/HTL interface. Parylene-D, containing additional chlorine functional groups compared to parylene-C, supports bidentate chelation, enabling effective interaction with uncoordinated Pb2⁺ and perovskite surface defects. This passivation layer significantly reduces nonradiative recombination and suppresses ion migration without affecting the morphology or electrical properties of large-area perovskites. The optimized parylene-D treatment yields PSCs with 23.75% efficiency and enhanced open-circuit voltage and fill factor. Stability tests demonstrate that the parylene-D-treated devices retain their initial efficiency after 1500 h under 10% relative humidity at room temperature and maintain 80% efficiency after 1200 h at 65 °C in a nitrogen environment. Furthermore, the scalability of this approach is validated by fabricating a large-area module (25 cm2 aperture area), achieving module and active area efficiencies of 19.44% and 20.59%, respectively. These results highlight the potential of parylene-D passivation via CVD as a practical and scalable strategy to enhance PSC performance and stability.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2500395"},"PeriodicalIF":10.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144101011","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}
