However, conventional gel polymer electrolytes (GPEs) face performance limitations at extreme temperatures. Current strategies focus on liquid component optimization but involve complex formulations and fail to meet extreme-environment requirements. This study develops a hydrogen bond-reinforced composite GPE (SA-GPE) by coincorporating Al2O3 nanoparticles and SSZ-13 zeolite into the PVDF-HFP matrix, forming a 3D interpenetrating network. The abundant surface hydroxyl groups on SSZ-13 and Al2O3 establish a robust multihydrogen-bond network with fluorine atoms (-F) in PVDF-HFP polymer chains. This interaction enhances the mechanical strength and thermal stability and effectively suppresses gel degradation at high temperatures while preventing polymer chain rigidification at low temperatures. Moreover, the hydrogen-bonding network ensures homogeneous filler dispersion, significantly inhibiting particle aggregation during cycling and maintaining structural integrity. Additionally, the filler-polymer interface facilitates rapid Li+ transport, and the Lewis acidic sites on Al2O3 promote lithium salt dissociation. The microporous structure of SSZ-13 confines PF6- mobility, further boosting Li+ transference. The SA-GPE demonstrates improved Li+ transference number (0.71), high ionic conductivity (2.38 mS/cm) even under -20 °C, and stable Li plating/stripping for 1000 h at 0.5 mA cm-2. When paired with LiFePO4, full cells maintain 92% capacity after 1000 cycles at room temperature and deliver excellent performance under extreme conditions (-20 °C-50 °C). This work provides a practical strategy for developing safe, wide-temperature-operable LMBs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"44 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209278","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 two-dimensional (2D) heterojunction-based devices face critical challenges. For instance, metal-semiconductor contacts can induce Schottky barriers and Fermi level pinning, which hinder carrier transport and degrade overall performance. To address these issues, this work proposes a vertical van der Waals heterojunction design, employing graphene (Gr) as the top electrode, tantalum nickel sulfide (Ta2NiS5) with a narrow-bandgap and anisotropy as the bottom electrodes, and molybdenum disulfide (MoS2) as the main light-absorbing layer. This architecture engineers reverse built-in electric fields at Ta2NiS5/MoS2 and MoS2/Gr interfaces and replaces Schottky contacts with ohmic-like transport, leveraging Ta2NiS5's anisotropy and interfacial asymmetry to integrate multiple functions. Under 660 nm light illumination (249.24 mW/cm2), it achieves a high photocurrent density of 171 mA/cm2 and an on/off ratio of 3.7 × 104. Under 808 nm light illumination, a self-powered anisotropy ratio of 6.03 is realized. It exhibits excitatory postsynaptic currents (EPSC) under 1064 nm light illumination with an ultralow energy consumption of 82 fJ, alongside bidirectional synaptic weight modulation via bias polarity and light pulse (duration, intensity, and number) control. This integrated design paves the way for advancing multifunctional optoelectronic devices in next-generation integrated systems and artificial intelligence applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"98 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209279","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, 2D perovskites (PEA)2MAn-1SnnI3n+1 are successfully prepared by introducing large phenylethylamine (PEA) cations. The effect of the dimensional structure on the photoelectric performances of (PEA)2MAn-1SnnI3n+1 is investigated. The electrical performances of (PEA)2MAn-1SnnI3n+1 photoelectric transistors are significantly improved by regulating the dimensional microstructure of the perovskites.

The standard deviation of performance parameters across 6 batches is less than 0.1 exhibiting a high level of consistency in device performance from batch to batch and good reproducibility. When stored in an N2 glovebox for 15 days, the electron mobility of the device remained at 5.96 cm2·V-1·s-1, confirming their good long-term reliability. Additionally, the photoelectrically controlled metal-oxide-semiconductor (MOS) inverter is constructed by connecting the (PEA)2MA6Sn7I22 photoelectric transistor with a resistor, thus enabling logic values to be converted via photoelectric control at a low on-power consumption of 18 μW. The gain of the inverter was still maintained at 30 under varying test conditions, exhibiting remarkable stability.

This study proposes an optical metasurface architecture consisting of nanodisks made from magneto-optical hyperbolic metamaterials, which enables detection of single chiral molecules. The nanodisks are engineered from alternating layers of metallic and magneto-optical dielectric materials, forming two-dimensional gratings that eliminate the need for traditional prism coupling. When phase-matching conditions are met, incident light couples into bulk plasmon-polariton modes ─whose resonantly enhanced and localized electromagnetic fields are highly responsive to changes in the surrounding medium. Chiral sensing is enabled by applying a magnetic field in the polar configuration, which induces differences in the reflection of left- and right-handed circularly polarized light, producing a measurable magnetic circular dichroism (MCD) signal. Two complementary MCD-based sensing strategies are demonstrated: refractometric detection of achiral analytes and chiroptical sensing of chiral molecules. The refractometric approach achieves an MCD sensitivity of S = 245 nm·RIU-1, while the chiroptical method enables detection at ultralow concentrations, with MCD peak values of |MCDp| = 4.71°, |MCDp| = 2.41°, and |MCDp| = 2.36°, corresponding to concentration ratios of four, two, and one molecule per unit cell, respectively.

Here, we demonstrate a virtual graphene/PbTe/Si heterojunction photodetector fabricated by magnetron sputtering, offering a scalable and cost-effective route to high-performance optoelectronic devices. The device exhibits a bias-tunable photoresponse governed by quantum tunneling at the PbTe/Si interface. At ±3 V biases, the photocurrent differs by nearly 2 orders of magnitude under low light intensities, whereas a symmetric response with less than 5% variation is observed at high light intensities. Exploiting this nonlinear response, we establish a dual-mode optical communication scheme, where plaintext is transmitted at high intensities and encrypted inverse codes are generated under low intensities. This built-in encoding functionality enables a simple yet effective strategy for secure optical communication without complex external circuits. Moreover, the CMOS-compatible fabrication process ensures seamless integration with existing silicon photonic platforms, highlighting the potential of this approach for future large-scale on-chip optical communication technologies.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"10 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209307","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 work, we report on the vanadium carbide-nickel hexacyanoferrate (V2CTx-NiHCF) composite electrodes with calciation charge storage capacity up to 140 mAh g-1 in concentrated (5 M) calcium-ion electrolyte, that is an order of magnitude higher than in dilute (1 M) electrolyte at a current density of 0.5 A g-1. The suppressed activity of water in the concentrated electrolyte enables anodic stability of V2CTx MXene while unlocking the redox storage capacity of both V2CTx and NiHCF. Further, the rate performance of V2CTx-NiHCF composite electrode is found to be 50% superior to that of the NiHCF electrode in 5 M calcium(II) bis(trifluoromethylsulfonyl)imide [Ca(TFSI)2] electrolyte. The charge storage dynamics of V2CTx-NiHCF composite electrodes are analyzed using 3D Bode analysis.

Although piezoelectric ceramics have excellent piezoelectric properties, their poor flexibility limits their application range. In the quest for better wearing comfort, nanocomposite polymers using elastomers as polymer matrices are rapidly emerging. However, there still exists a challenge to achieve uniform dispersion of nanofillers in the polymer matrix due to their significant difference in surface energy. In this work, a novel thermoplastic polyamide elastomer (TPAE) based nanocomposite with strong interfacial strength and uniform dispersion was proposed, which was achieved through incorporating γ-aminopropyltriethoxysilane (KH550)-functionalized BaTiO3 nanoparticles (KH550@BTO) into in situ polycondensation of TPAE for flexible piezoelectric nanogenerators (PENGs) with sensing capability. The PENGs not only possessed excellent mechanical properties (elongation at break ∼ 400%) but also exhibited good piezoelectric behavior (VOC ∼ 19 V, ISC ∼ 121 nA). Moreover, the PENGs exhibited excellent durability, stability (6000 cycles without degradation), and rapid response time (∼21 ms), which was superior to those of most reported BTO-based nanocomposites. Based on the performance, the PENG could be used to monitor human motions after the assembly of wireless wearable devices, and different badminton serving postures were further recognized by the assistance of machine learning. This work provides an innovative approach for the preparation of soft piezoelectric nanocomposites, which is helpful for self-powered and wireless flexible sensors with better performance and more comfortable use in human motion monitoring and recognition.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"17 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209282","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 general, calcium oxalates are pathological biominerals found in kidney stones and as microcalcifications (MCs) in breast and thyroid cancers. In breast cancer MCs, COD crystals are exclusively associated with benign lesions, and we have recently shown that they suppress breast precancer progression in vitro. Here, we studied the influence of synthetic calcium oxalate crystals─both COD and calcium oxalate monohydrate (COM)─with different morphologies and properties on crystal–cell interactions. We found that the less negatively charged crystals exhibited a greater tendency to aggregate and, as aggregates, attach better to cells, particularly to the cells of an invasive breast cancer cell line. We did not find any association between crystallinity, surface area, and solubilities of the crystals and attachment to cells. The crystal types that did attach efficiently to the cells, namely, COD with a thin or thick bipyramidal morphology, had the greatest impact on cell phenotype and functionally delayed cell growth, most probably through contact inhibition. Notably, in terms of morphology and size, these crystals resembled COD MCs found in benign breast tissues, suggesting that they are involved in a mechanism of tumor suppression.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"62 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203938","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}
