However, the mechanisms linking concentration, conformation, and nanoparticle stabilization in full‐length reflectins remain poorly understood. Here, coarse‐grained molecular dynamics simulations of Doryteuthis pealeii reflectin A2 (RfA2) across five concentrations are combined with dynamic light scattering (DLS) and circular dichroism (CD) measurements. The simulations reveal rapid initial protein aggregation followed by slower structural maturation, during which interprotein interaction energy and contact networks continue to evolve. A simulation‐derived concentration‐dependent crossover separates multi‐cluster vs single‐cluster regimes and DLS shows larger assemblies at higher experimental concentrations. The simulations further delineate region‐specific secondary‐structure reorganization and CD demonstrates concentration‐sensitive structural changes with a distinct secondary‐structure redistribution. Moreover, the simulations predict concentration dependence in the contribution of intermolecular contact network reorganization; the L1, L3, and L5 linker regions supplied many of these contacts, with L3 providing the dominant contribution. Overall, these findings establish a molecular‐level framework where concentration governs RfA2 self‐assembly and continued conformational and intermolecular reorganization during maturation, providing insight into sequence‐ and assembly‐level principles regarding iridophore optical function and reflectin‐based materials design.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"20 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374423","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 employ host‐guest encapsulation to functionalize otherwise underutilized pore space of macrocycle‐based MOFs by introducing an organic salt guest, N‐(2‐trimethylammonioethyl)pyridinium dibromide (PyBr) within the cage‐like units of resorcinarene‐based uranium‐organic frameworks (UOF‐1D and UOF‐2D). While maintaining the host framework well, such a modification creates a Br − /N + ‐rich pore microenvironment in as‐synthesized PyBr@UOF‐1D and PyBr@UOF‐2D. The resulting materials exhibit gas‐phase iodine uptakes of up to 3.50 g·g −1 , markedly exceeding those of the pristine frameworks, free guests, and physical mixtures. Spectroscopic analyses and calculations show that confinement enriches iodine around guest sites, where Br − polarizes I 2 and promotes polyiodide/polyhalide formation, while N + electrostatically stabilizes the resulting anions. The enhanced capture originates from improved pore utilization through cooperative confinement and guest‐derived binding interactions. Its successful application to both 1D and 2D UOFs demonstrates the adaptability of guest‐engineered pore microenvironments across distinct architectures, offering a route toward target‐specific separations.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"18 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374432","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}

Here, a multi‐modulation strategy via thickness‐confined Mo‐VO 2 /CNTs composite films is adopted to resolve these issues. By controlling the in‐situ growth on flexible CNTs films, Mo‐VO 2 with an appropriate thickness can partially allow IR information transmission of CNTs. The high‐conductivity CNTs scaffold effectively pulls down the radiative baseline, escaping the “extreme‐emissivity trap”, while Mo 6+ ‐induced band modulation and interfacial charge redistribution optimize the modulation amplitude (Δε) to 0.335 (0.795–0.460). Crucially, the CNTs network provides the massive free‐electron reservoir required to overcome shielding deficiency of VO 2 , elevating EMI shielding performance to an exceptional 62–76 dB. Furthermore, leveraging Joule heating effect as a compensatory dimension, the composite films enable active IR camouflage across extreme thermal mismatches (60 C–75°C). This work integrates desirable baseline IR optical modulation with highly efficient electromagnetic protection, redefining the design paradigm of advanced protective materials.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"11 4 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374433","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}

Nevertheless, the insufficient electrical conductivity of NiO x and the limited number of binding sites on its surface lead to incomplete monolayer coverage, resulting in substantial interfacial charge losses that constrain efficiency improvements. To address these issues, we introduce hydroxyl‑rich sodium gluconate (SG) into the NiO x solution. Gluconate anions from SG modulate the electronic properties of NiO x , thereby enhancing its conductivity. Meanwhile, the abundant hydroxyl groups along the SG backbone furnish additional hydrogen‐bonding sites for the subsequent adsorption of the SAM, promoting the formation of a compact and well‐ordered interfacial molecular layer. This dense SAM not only suppresses leakage currents but also optimizes the energetic cascade at the heterojunction, ultimately enabling the resulting IPSCs to achieve a power conversion efficiency of 26.24%. During maximum‐power‐point operation under ISOS‑L‑1 protocol, the optimized device preserves 91.6% of the starting output after 1000 h.

Here, we develop a co‐assembly strategy by incorporating two bisphosphonic acid molecules with distinct linker structures, denoted S1 and S2, into the widely used carbazole‐based SAM [4‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)butyl] phosphonic acid (MeO‐4PACz). Compared with S1, S2 exhibits improved conformational compatibility with MeO‐4PACz. The S2/MeO‐4PACz pair also features stronger hydrogen bonding and π–π interactions. In addition, S2 possesses a larger molecular dipole and adsorbs more favorably on indium tin oxide. These molecular attributes promote more continuous and spatially uniform coverage. They also strengthen substrate anchoring and homogenize the interfacial potential distribution. The resulting S2‐based co‐assembled SAM (Co‐SAM) provides favorable energy‐level alignment, facilitates hole extraction, and suppresses nonradiative recombination. It also reinforces the buried interface against cyclic thermal stress. Residual stress accumulation is alleviated, interfacial morphology is preserved, and perovskite phase degradation is retarded. Consequently, inverted perovskite solar cells (PSCs) based on the S2 Co‐SAM achieve a power conversion efficiency of 27.01% and retain 92.8% of their initial efficiency after 500 temperature cycles between −40°C and 85°C.

By leveraging the intrinsic learning capability of organic electrochemical diodes (OECDs), multiple logic functions are realized within a single diode‐resistor configuration. The channel conductance of each OECD is dynamically modulated by the polarity and frequency of the input voltage, enabling seamless reconfiguration to execute custom logic operations (e.g., AND/OR and XOR/unknown).

This Review frames PEMWE anode degradation as a multilevel interfacial stability problem. It first defines the near‐surface stability window of Ir/Ru active sites through valence evolution, hydroxylation, lattice‐oxygen participation, reconstruction and metal dissolution. It then shows how this window is reshaped in MEAs by catalyst‐layer percolation, ionomer distribution, pore architecture, porous transport layer (PTL)/catalyst‐layer contact, membrane contamination, metal migration and dynamic operating stresses. Layered diagnostic strategies are summarized to trace macroscopic performance decay back to specific interfacial instability pathways. Future directions are discussed in terms of standardized evaluation, realistic operating environments and data‐driven materials‐interface‐device optimization.
