This electrolyte not only maintains good elasticity but also significantly enhances mechanical strength, demonstrating robust fatigue resistance. By integrating this electrolyte with ammonium molybdate-doped polypyrrole electrodes, a stretchable/compressible supercapacitor is assembled. The resultant supercapacitor exhibits a remarkable specific capacitance retention of 64.5% after 1000 stretch-release cycles under 200% tensile deformation and 68.7% after 1000 compression-release cycles under 80% compression deformation.

However, in vivo detection of PCMT remains challenging. Here, we report the aspartate isomerization-regulated in situ assembly of peptides into supramolecular probes within living cells for PCMT detection in bladder cancer. The peptide consists of alternating hydrophobic and hydrophilic residues and contains an isoAsp residue as a kinked site to prevent the facial amphiphilicity of the peptide. Exposure to PCMT converts isoAsp to Asp within the peptide, thereby promoting its assembly into nanofibers. Incorporation of 7-nitro-2,1,3-benzoxadiazole (NBD) into the nanofibers enables PCMT detection based on hydrophobicity-dependent fluorescence of NBD units. Both cellular and animal studies confirm the capability of supramolecular probes for efficient detection of PCMT. Our finding demonstrates an efficient strategy for regulating peptide assembly in living systems and thus provides a new tool for creation of biomedical agents in the future.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"15 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518351","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 this work, we propose a lattice reconstruction strategy combining polyvinylpyrrolidone-assisted wet chemistry and calcination to prepare the aluminum-modified LiNi0.83Co0.11Mn0.06O2 (ANCM). Our method offers distinct advantages in tailoring birth defects (residual alkali and rocksalt phase), reducing Li vacancies and oxygen vacancies, exhibiting gradient Ni concentration distribution, suppressing the Li/Ni intermixing defects, lowering the lattice strain before and after recycling, and inhibiting the microcracks. The ANCM constructs robust crystal lattices and delivers an initial discharge capacity of 155.3 mAh/g with 89.2% capacity retention after 200 cycles at 5 C.

Typically, these pyroelectric charges are considered unstable and dissipate quickly through interactions with the external environment. Consequently, the pyroelectric effect has been largely overlooked in ferroelectric field-effect transistors. In this work, we leverage the van der Waals interface of hBN to achieve a substantial and long-term electrostatic gating effect in graphene devices via the pyroelectric properties of a ferroelectric LiNbO3 substrate. Upon cooling, the polarization change in LiNbO3 induces high doping concentrations of up to 1013 cm-2 in the adjacent graphene. Through a combination of transport measurements and noncontact techniques, we demonstrate that the pyroelectric charge accumulation, as well as its enhancement in electric fields, are responsible for this unexpectedly high doping level. Our findings introduce a novel mechanism for voltage-free electrostatic gating control with long retention.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":""},"PeriodicalIF":9.6,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143513994","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}

The self-assembly process was governed by polyvalent hydrogen bonding interactions between the amphiphilic Tween-20 and tiopronin-capped NPs, with the amphipathic nature of Tween-20 primarily dictating the transformation from 1D to 3D structures. Notably, the NP size influences the assembly process, with the 2 nm particles demonstrating a well-regulated, pH-stable, and reversible assembly capability.

Integration of HE-5 into all-solid-state batteries (ASSBs) with NCM83 cathodes and a Li–In anode enables outstanding electrochemical performance, sustaining 70% capacity retention over 1600 cycles at a 4 C rate. Moreover, the high configurational entropy stabilizes the electrolyte’s structure at elevated voltages, enabling stable operation at 5.0 V without significant degradation.
