In this context, thiol engineering is one of the most widely explored sensing strategies for Hg(II) ions. However, the development of efficient 2D thiol-based photonanozymes for the selective detection of Hg(II) remains relatively underexplored. To address this, we have developed L-cysteine-functionalized borophene nanosheets (L-Cys@BNS) as a nanozyme for the selective colorimetric detection of Hg(II). The L-Cys@BNS acts as an efficient light-driven peroxidase-mimic nanozyme for the oxidation of 3,3′,5,5′-Tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H2O2). Upon interaction with Hg(II), the selective thiol-binding of L-cysteine results in a concentration-dependent change in TMB oxidation, yielding a visible colorimetric response. The developed sensor exhibits good linearity (R2 = 0.9877) within the range of 0-50 ppb. The limit of detection was 2.45 ppb, and the limit of quantification (LOQ) was 7.42 ppb, along with satisfactory recovery in real water (88.89~106.24%). The spin-polarized Density Functional Theory (DFT) reveals that the borophene nanosheets (BNS) after functionalization with L-cysteine provide accessible thiol sites for mercury binding. DFT calculations further revealed that Hg(II) coordinates strongly to the thiolate sulfur of L-Cys@BNS, forming an S–Hg–Cl complex with a calculated S–Hg bond length of 2.36 Å. This coordination was accompanied by Hg–Cl bond elongation from 2.29 to 2.43 Å, while electronic-structure analysis supported S–Hg interactions and indicated that electronic states remained available at the Fermi level. Therefore, this work demonstrated that L-Cys@BNS provides an effective photonanozyme-based platform for selective Hg(II) detection, with the underlying sensing mechanism supported by its electronic-structure characteristics.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"56 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, local polarization heterogeneity is regulated through moderate Sr substitution while preserving a dominant Pbam antiferroelectric framework. Atomic displacement analysis reveals locally varying correlations between antipolar and polar-like configurations, with weakly correlated transitional regions that disrupt collective switching and broaden the field-induced polarization response. The enhanced dielectric diffuseness (γ = 1.68 for x = 0.01) is consistent with the increased polarization heterogeneity. Consequently, Pb 0.97 La 0.02 Sr 0.01 (Zr 0.6 Sn 0.4 ) 0.97 Ta 0.02 O 3 achieves a recoverable energy density of 12.87 J cm -3 and an efficiency of 85.7% at 720 kV cm -1 , together with excellent cycling/frequency stability and further releasing 9.67 J cm -3 at 600 kV cm -1 within 113 ns.

Lead-free ternary copper halides of the Cs–Cu–I system combine nontoxicity and air stability with bright luminescence arising from self-trapped excitons. In solution processing, the lack of solvent orthogonality makes it difficult to stack CsCu2I3 and Cs3Cu2I5 layers within a single device. Here, we adapt the molten salt evaporation concept, previously developed for lead-halide perovskite photovoltaics, to the Cs–Cu–I system through a vacuum molten salt deposition strategy. Premixed CsI and CuI form a homogeneous molten source that mitigates the disparate volatilities of the two precursors and enables compositionally coupled evaporation. Phase-selective X-ray diffraction, X-ray photoelectron spectroscopy, and optical characterization confirm that the 1:2 and 3:2 sources yield the targeted one-dimensional (1D) CsCu2I3 and 0D Cs3Cu2I5 films, respectively. Because the process is solvent-free, the two phases can be deposited sequentially between transparent PDMS spacers to form an encapsulated PDMS/CsCu2I3/PDMS/Cs3Cu2I5/PDMS core, and adding a spatially patterned, unencapsulated Cs3Cu2I5 dynamic layer on top yields an integrated label that combines three independent security primitives. First, macroscopic transparency provides physical stealth, revealing nothing to the naked eye. Second, spectral gating with 325 nm excitation and a 510 nm long-pass filter unmasks the yellow CsCu2I3 pattern beneath the intense blue Cs3Cu2I5 emission. Third, moisture triggers a reversible 0D-to-1D phase conversion of the dynamic layer that executes a localized bit-flip in the optical code. A standalone unencapsulated Cs3Cu2I5 film and the integrated label remain stable for 200 days in ambient air, the dynamic layer withstands 20 hydration–dehydration cycles, and the encapsulated core withstands 20 days of water immersion. By combining solvent-free, phase-selective deposition with multistimulus optical encoding, this work provides a lead-free multilayer platform for optical encryption.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"17 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226007","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}

Simple-cubic (sc) structures are considered energetically unfavorable in elemental solids and have previously been confirmed only in polonium. Here, we report the direct observation of a previously unrecognized sc-Ag formed under far-from-equilibrium conditions. Using electron beam irradiation inside a high-resolution transmission electron microscope as a trigger, we induced the radiolytic decomposition of silver iodide (AgI) and tracked the in situ formation of silver crystals in real time. Continuous imaging revealed that sc-Ag formation strongly depends on the polymorph of the precursor and occurs selectively from metastable γ-AgI. The sc-Ag exhibited unusually high chemical reactivity, undergoing gradual oxidation into silver oxide under high-vacuum conditions where conventional fcc-Ag remains stable. These findings demonstrate that irreversible crystal formation pathways can kinetically stabilize crystal structures inaccessible under near-equilibrium conditions and extend a previously inaccessible structural limit of metallic bonding.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"29 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226545","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}

Herein, we go beyond this conventional paradigm by introducing a Ca2+-formed band structure modulation in the host lattice to dramatically boost the NIR-II emission of lanthanide-doped nanoparticles. Rational doping of Ca2+ ions restructures the energy levels, enabling the probe to efficiently capture excitation energy and channel it toward NIR-II-emitting lanthanide activators. This Ca2+-induced band structure modulation mechanism not only enhances the absorption cross section but also accelerates energy transfer to the NIR-II-emitting states. As a result, the designed nanoprobes exhibit excellent photostability and a high quantum yield. In vivo bioimaging demonstrates that the resulting nanoprobes enable deep-tissue visualization with an improved signal-to-background ratio.
