Here, by analyzing the temperature-dependent Raman peak profiles of highly ordered ferroelectric domains in HOIPs, a framework to systematically investigate the dimensionality (n)-dependent phonons that are critical to ferroelectric behaviour is established. By tracking phonon evolution across the ferroelectric-to-paraelectric phase transition in HOIPs with different n, characteristic modes associated with the ferroelectric symmetry-breaking process are identified. Notably, in the ferroelectric phase of (BA)2(MA)2Pb3Br10 (n = 3), these modes exhibit a redshift compared to those in (BA)2(MA)Pb2Br7 (n = 2), reflecting a reduced energy barrier for ferroelectric switching. Density functional theory (DFT) calculations further correlate these modes with their spectral signatures in Raman spectroscopy, particularly highlighting zone-boundary modes that diminish upon transitioning to the paraelectric phase. Polarized Raman mapping further reveals adjacent ferroelectric domains with orthogonal polarization orientations, directly linking phonon activity to domain configuration. This work elucidates the role of phonons in HOIP ferroelectricity, offering insights for tailoring domain-related properties in ferroelectric devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2419685"},"PeriodicalIF":27.4,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232764","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}

While intense terahertz fields drive metal-insulator transitions and ferroelectricity via soft phonon modes, recent theory suggests that twisted light with orbital angular momentum (OAM) offers a distinct route to manipulate ferroelectric order and stabilize topological excitations including skyrmions, vortices, and Hopfions. Control of ferroelectric polarization in quasi-2D CsBiNb2O7 (CBNO) is demonstrated using non-resonant twisted ultra-violet (UV) light (375 nm, 800 THz). Combining in situ X-ray Bragg coherent diffractive imaging (BCDI), twisted optical Raman spectroscopy, and density functional theory (DFT), three-dimensional (3D) ionic displacements, strain fields, and polarization changes are resolved in single crystals. Operando measurements reveal light-induced strain hysteresis under twisted light-a hallmark of nonlinear, history-dependent ferroelastic switching driven by OAM. Discrete, irreversible domain transitions emerge as the topological charge ℓ is cycled, stabilizing non-trivial domain textures including vortex-antivortex pairs, Bloch/anti-Bloch points, and merons. These persist after OAM removal, indicating a memory effect. Competing mechanisms are discussed, including multiphoton absorption, strain-mediated polarization switching, and defect-wall interactions. The findings establish structured light as a tool for deterministic, reversible control of ferroic states, enabling optically reconfigurable non-volatile devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2415231"},"PeriodicalIF":27.4,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232762","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 white plasmonic metasurfaces emulate the cooling effects of clouds, reducing substrate temperatures by a relative -10 °C under standard solar illumination through backscattering. In contrast, transitioning to a grey state with a nanocomposite absorber suppresses backscattering and enables efficient light trapping, resulting in a relative +10 °C temperature increase compared to conventional black absorbers. These findings introduce a novel approach to localized thermal management, distinct from traditional passive cooling strategies that rely on high-emissivity materials. The metasurfaces' low-emissivity properties and visible appearance open opportunities in advanced camouflage, stealth technologies, and thermal energy solutions.

Herein - for the first time - micro- and macro-sized photocatalytically active 3D printed objects are introduced via a dual-function photoresin using a ruthenium(II) complex containing monomer as both a photoinitiator for the 3D printing process and as the active photocatalyst within the printed structure. The approach leverages the spatial and temporal control afforded by light-induced 3D printing techniques during both one- and two-photon printing to precisely position the photocatalyst within intricate geometries using a pentaerythritol triacrylate (PETA) based resin. The successful incorporation of ruthenium(II) complexes is demonstrated via time-of-flight secondary-ion mass spectrometry (ToF-SIMS) into desired sections of 3D-printed objects. The one- and two-photon fabricated architectures show photocatalytic activity in the C─H arylation of activated aryl bromides. The potential of tailored catalytically active 3D objects is exemplified by one of the microscale designs.

However, reaction heterogeneity during cycling compromises their rate capability and cycle life. While this nonuniformity is commonly attributed to sluggish charge transport, it is demonstrated here that the thermodynamic properties of the electrode material play an equally critical role. Through combined X-ray fluorescence microscopy and absorption near-edge structure spectroscopy, reaction distributions in LiFePO4 (LFP) and LiNi0.6Mn0.2Co0.2O2 (NMC) thick electrodes with matched porosity and tortuosity are compared. LFP electrodes develop pronounced depth-oriented state-of-charge (SOC) gradients that worsen with increasing discharge rates, whereas NMC maintains much more uniform SOC distributions under such conditions. This difference originates from their distinct SOC dependence of equilibrium potentials and is quantifiable through a dimensionless \"reaction uniformity\" number. Intriguingly, LFP thick electrodes also exhibit lateral SOC variations that strengthen during slow discharge. The enhanced reaction uniformity in NMC correlates with better active material utilization and slower capacity fade than LFP, highlighting electrode thermodynamics as a key design consideration for thick electrodes.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2502299"},"PeriodicalIF":27.4,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232765","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}

An ideal robot electronic skin should offer full-body coverage, multiplexing, stretchability, and multifunctionality, but integration is challenging due to the robot's elongated structure. This work presents a stretchable electronic armor (E-armor) with a 3D crosslinked structure that enables 300 mm full coverage while accomplishing multiplexed simultaneous tactile and strain sensing through bioinspired artificial synapse mechanisms. The E-armor integrates 48 tactile sensing points through bilayer co-electrode strategy, reducing wiring while combining triboelectric encoding intelligence with innovative stretchable triboelectric interlinked films (TIFs) to form a triboelectric artificial synapse that generates digitally encoded signal pairs upon contact. A convolutional neural network and long short-term memory network (CNN-LSTM) deep learning framework achieve 99.31% accuracy in identifying multi-point tactile signals. A sodium alginate/polyacrylamide/sodium chloride (SA/PAM/NaCl) conductive hydrogel serves as a strain sensing element, providing excellent stretchability and biocompatibility, and allowing precise inference of bending angles at 12 strain sensing edges. A compliance control strategy coordinates tactile and strain signals to autonomously adjust continuum robot postures while ensuring smooth operation.
