Herein, the adjustable property of organic ligands is exploited in metal–organic frameworks (MOFs) to develop a hierarchical composite electrolyte, incorporating heterogeneous and spatially confined MOF nanofillers into a poly-1,3-dioxolane matrix. The defect-engineered University of Oslo-66 MOFs (UiO-66d) with tailored Lewis acidity can separate ion pairs and optimize Li⁺ migration through weakened solvation effects, thereby enhancing ion conductivity by over sixfold (0.85 mS cm⁻¹@25 °C). At the lithium anode side, a densified University of Oslo-67 MOFs (UiO-67) layer with conjugated π electrons facilitates anion participation in the solvation sheath, promoting anion reduction and thereby forming LiF/Li₃N-dominated solid electrolyte interphase for isotropic Li deposition. The as-assembled Li||LiFePO₄ full cell delivers superior cycling stability with 92.7% of capacity retained over 2000 cycles at 2 C. Notably, the developed electrolyte demonstrates excellent compatibility with high-voltage cathodes, achieving 80% capacity retention with LiNi_0.5Co_0.2Mn_0.3O₂ over 630 cycles. This work provides valuable insights into decoupling transport and interfacial challenges in solid-state lithium batteries, paving the way for advanced battery technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"70 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901794","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}

However, their polymorphic and prone to aggregation characteristics present challenges in both their production and practical application. Here, mutant recombinant spidroins are reported forming hydrogels rapidly and controllably at 37 °C and with visible light irradiation. In the mutant spidroins phenylalanine residues (F) are systematically substituted by tyrosine residues (Y) in repeat motifs of (GGX), which contributes to the self‐assembly of <jats:italic>β</jats:italic>‐sheet and further formation of amyloid‐like nanofibrils. As expected, micellar/globular spidroins solution converts to spidroins hydrogel composed of nanofibrils network and subsequently further crosslinked by di‐tyrosine. The conformation transformation process is verified by spectroscopy, transmission electron microscopy (TEM), and molecular dynamics simulation. Furthermore, the spidroin hydrogels are used as bioink and biomimetic cellular scaffolds according to their good biocompatibility, shear thinning properties, and nanofibril network structure. The findings reveal the structural transformation mechanism of spidroins and expand their applications in biomedical engineering.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886963","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}

Compared to natural lipase, the obtained CDs not only exhibit superior catalytic activity (2.85 times increase in V<jats:sub>m</jats:sub>) but also have a broader range of substrate concentrations (0–8.0 m<jats:sc>m</jats:sc>) and substrate types (fatty ester, aromatic ester, phosphate ester), along with simpler catalytic conditions and superior stability.

The results of theoretical calculations and comparative experiments demonstrate that the adsorption sites of CDs are located on the nitrogen atoms of the polycyclic dipeptide. Furthermore, a membrane integrated with CDs (membrane‐catalyst) is constructed, through which the instantaneous hydrolysis of esters can be realized.

Herein, highly selective sites are developed for photoreduction CO<jats:sub>2</jats:sub> to HCOOH and CO based on asymmetrically coupling different ratios of Ni and Co loaded on crystalline carbon nitride (CCN) by an alloying synthesis strategy, which is confirmed by high‐resolution transmission electron microscopy (HRTEM) imaging, X‐ray diffraction (XRD) patterns, and X‐ray photoelectron spectroscopy (XPS) spectra. In situ Fourier transform infrared spectra suggest that the key intermediate *OCHO to HCOOH pathway prefers to form on Ni sites, while *COOH to CO pathway tends to generate on Co sites, and the characteristic peaks intensity of the two key intermediates are stronger with the synergistic effects of NiCo bimetallic, further verified by the theory calculations.

Nevertheless, the computing capacity of RC systems is limited by the material‐dependent physical dynamics of reservoir devices. In this study, an efficient neuromorphic reservoir device with adjustable reservoir states, achieved through the development of an electrically tunable three‐terminal charge trap memory, is introduced. This device utilizes molybdenum disulfide (MoS<jats:sub>2</jats:sub>) as the channel material and a perhydropolysilazane‐based charge trap layer. Notably, the absence of a tunneling layer in the device structure enables dynamic resistive switching, characterized by outstanding endurance and an excellent memory window. Furthermore, by implementing a simple input decay and refresh scheme, a reconfigurable neuromorphic device capable of multiple feature extraction and functioning as an artificial synapse is developed. The device's efficacy is validated through device‐to‐system‐level simulations within a hardware‐based wide RC (WRC) system, resulting in an improved recognition rate in the MNIST hand‐written digit recognition task from 87.6% to 91.0%, a testament to the enhanced computing capacity.

This underscores the urgent necessity for the development of effective carbon anti-oxidation strategies. This comprehensive review initially explores the complex mechanisms underlying the oxygen reduction/oxygen evolution reactions (ORR/OER) and the prevalent issue of carbon corrosion in carbon-based materials.

Understanding the underlying molecular scale mechanisms is then also crucial for biomimetic applications. In this study, it is illustrated how the effective integration of physically‐based machine learning with scientific interpretations can lead to significant physical insights and enhance the predictive power of an existing microstructure‐inspired model. A symbolic data modeling technique, known as Evolutionary Polynomial Regression (EPR), is employed, which integrates regression capabilities with the genetic programming paradigm, enabling the derivation of explicit analytical formulas for deducing structure‐function relationships emerging across different scales, to investigate the impact of protein primary structures on supercontraction. This analysis is based on recent multiscale experimental data encompassing a diverse range of scales and a wide variety of different spider silks. Specifically, this analysis reveals a correlation between supercontraction and the repeat length of the MaSp2 protein as well as the polyalanine region of MaSp1. Straightforward microstructural interpretations that align with experimental observations are proposed. The MaSp2 repeat length governs the cross‐links that stabilize amorphous chains in dry conditions. When hydrated, these cross‐links are disrupted, leading to entropic coiling and fiber contraction. Furthermore, the length of the polyalanine region in MaSp1 plays a critical role in supercontraction by restricting the extent of crystal misalignment necessary to accommodate the shortening of the soft regions. The validation of the model is accomplished by comparing experimental data from the Silkome database with theoretical predictions derived from both the machine learning and the proposed model. The enhanced model offers a more comprehensive understanding of supercontraction and establishes a link between the primary structure of silk proteins and their macroscopic behavior, thereby advancing the field of biomimetic applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"20 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886967","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}
