However, the impact of chiral selectivity on α-syn aggregation and its regulatory mechanisms remain ambiguous. In this work, it is synthesized chiral carbon nanodots (CNDs), including L-CNDs, D-CNDs, and DL-CNDs, and found that D-CNDs exhibited the most potent inhibitory effect on α-syn aggregation. ¹H-¹⁵N heteronuclear single quantum coherence nuclear magnetic resonance spectroscopy revealed that CNDs primarily interact with α-syn through electrostatic interactions, with D-CNDs specifically targeting key aggregation-prone residues, thereby disrupting β-sheet formation and reducing fibril assembly. In contrast, L-CNDs and DL-CNDs exhibited limited inhibitory effects, attributed to their weak affinity for the non-amyloid-β component region. Moreover, CNDs efficiently crossed the blood-brain barrier, and D-CNDs significantly reduced α-syn accumulation, alleviated neuronal damage, and ameliorated cognitive function. This work underlines the critical role of chirality in modulating α-syn aggregation and provides a novel strategy for developing enantiomer-selective inhibitors for PD therapy.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2500557"},"PeriodicalIF":10.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075215","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}

Nonetheless, the growth of Zn dendrites and side reactions, resulting in degraded cycling stability, poses a substantial obstacle to the practical implementation of AZIBs. Herein, it is demonstrated that creatinine (Cre), a metabolite derived from muscle, serves as a multifunctional electrolyte additive that enhances the performance of AZIBs. Both experimental and theoretical analyses reveal that Cre, when used as an electrolyte additive, fulfills three key roles: it disrupts the solvation structure of Zn2+ by carbonyl group; it forms a water-deficient electric double layer, thereby reducing the likelihood of interfacial water decomposition; and it promotes the deposition of Zn2+ on the (002) planes, facilitating the uniform deposition. The Zn||Zn symmetric cell utilizing a 1 M ZnSO4 electrolyte with the addition of 0.3 M Cre exhibits stable cycling for 900 h under the condition of 1 mA cm-2 and 1 mAh cm-2, representing an over 11-fold increase in lifespan.

This study proposes a novel hybrid metal-based ink formulation pathway and develops a particle-free Ag-Cu hybrid metal-organic decomposition (MOD) ink. When sintering under N2 the in situ formed Ag and Cu nano-particulates during the sintering process self-regulate into a unique vertical compositional gradient with Cu dominant on top and the majority of Ag existing beneath. Highly conductive (1.88 ± 0.7 × 106 S m-1) metallic patterns are fabricated by single-step inkjet printing at low temperature (<150 °C) on both rigid and cellulose fiber substrates.

Strengthening the adsorption ability of the electrocatalyst is crucial to promoting water dissociation in the alkaline HER, whereas too-intense adsorption will poison the active sites. Herein, the adsorption ability of NiFeP is modulated by nonmetal F doping for an efficient and durable alkaline HER. F incorporation in NiFeP (NiFePF) tailors the electronic structure of Ni, Fe, and P, optimizing the adsorption of *OH/*H on the active sites. The balanced *OH/*H adsorption facilitates the water dissociation and hydrogen evolution of NiFePF, exhibiting the smaller overpotential of 233 mV at 100 mA cm-2. Furthermore, NiFePF achieves 1 A cm-2 at an overpotential of only 231 mV under 30 wt% KOH. The balanced *OH/*H adsorption ability in NiFePF facilitates the desorption of *OH and alleviates the poisoning active center, limiting the surface hydroxylation of NiFePF to a few nanometers. This enables NiFePF to remain stable for 360 h, demonstrating its commercial potential.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2500199"},"PeriodicalIF":10.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075213","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, existing mechanical self-assembly fabrication strategies for micro-nano surface patterns face challenges in microfabrication compatibility and industrial repeatability. Here, a microfabrication-compatible light-controlled mechanical self-assembly is proposed for programmable and industrially standardized micro-nano surface patterning. By introducing light-controlled high spatial resolution soft-constraint boundaries and surface instability-induced mechanical self-assembly into film/substrate systems, a develop-free and industrially standardized manufacturing process with microfabrication compatibility is demonstrated. Moreover, trans-scale patterns spanning from 5 to 1000µm, 2D highly-ordered patterns, and dynamic patterns mimicking Chinese pandas eating bamboo are achieved. Design criteria for programmablely fabricating trans-scale patterns and the mechanical mechanism of orderliness evolutions in 2D self-assembly under arbitrary exposure angles are explained. Furthermore, by applying the highly-ordered micro-nano patterns, a new self-adaptive wideband gas detection system based on tunable micro-gratings is developed and methane is detected. This study can advance strategies for programmable surface micro-nano patterns and lay the foundation for the applications of surface functional devices.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2500319"},"PeriodicalIF":10.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075221","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}

In this study, the impact of dielectric screening is investigated on hot carrier dynamics in monolayer MoS2 using transient absorption microscopy. The results demonstrate that a high dielectric constant (high-κ) metal-oxide substrate effectively suppresses the Coulomb potential, reducing carrier scattering and recombination while significantly enhancing hot carrier diffusion length and coefficient compared to a conventional quartz substrate.

This study addresses these limitations by developing thin-film OECTs (TF-OECTs) using solid electrolytes with significantly reduced ionic liquid concentrations and introducing a doped organic semiconductor film (DOSCF) as an interlayer between the gate and electrolyte. This strategy enables TF-OECTs to achieve film-like mechanical properties while maintaining high performance, including a maximum transconductance (gm) of 5.05 mS, operational voltages below 1 V, and exceptional stability over 1000 switching cycles. The devices also exhibit superior flexibility, enduring over 2000 bending cycles with minimal performance degradation. Their potential is demonstrated in ferric ion sensing, achieving an ultralow detection limit of 15 nm with a high selectivity of 0.7 mA dec-1, and in neuromorphic computing, where they emulate synaptic behaviors and achieve a 96.7% image recognition accuracy after training with artificial neural networks (ANN).
