Organic light-emitting transistors (OLETs), which integrate dual functionalities of current amplification from organic field-effect transistor (OFET) and light emission from organic light-emitting diode (OLED) within a single device, have emerged as a promising display technology with simplified circuitry and reducing power consumption. Over the past two decades, substantial progress has been achieved in OLET device architectures, efficiencies, and multifunctional applications. In particular, new lateral area-emission OLETs, featuring a stacked OFET-OLED architecture, intrinsically form a microcavity that offers great potential for effective spectral narrowing. In this Perspective, we summarize these impressive advances in the OLET field with a specific emphasis on narrow-band-emission OLETs based on laterally stacked device geometry. We further discuss prospective strategies for simultaneously enhancing efficiency and spectral narrowing, thereby advancing OLETs toward practical high-definition, low-power display applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73319"},"PeriodicalIF":26.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147855509","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, we establish a helical photonic confinement strategy by embedding NIR-emissive Au13 nanoclusters into chiral nematic mesoporous silica (CNMS). Precise matching between the chiral photonic bandgap and cluster emission yields strongly enhanced NIR-CPL with a glum of -0.4, enabling direct discrimination of left- and right-handed circularly polarized emission in the NIR region. This system realizes the first high-contrast, CPL-resolved near-infrared (night-vision) imaging based on intrinsic cluster emission, without external polarization optics. The Au13 clusters undergo reversible assembly-disassembly within helical nanochannels, allowing controllable NIR-CPL switching and handedness inversion. Mechanistic studies confirm that the CPL enhancement originates from chiral photonic propagation modulation rather than intrinsic emitter chirality. This helical-confinement principle is extendable to multicolor metal clusters, offering a general route toward high-efficiency CPL materials.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73316"},"PeriodicalIF":26.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147830971","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}

This internally activated reactivity enables the rapid formation of graphitic aerogel monoliths with multilevel architecture-macroporous frameworks decorated with microtubular arrays and nanoscale features-within seconds in a single process. As energy storage electrodes, these hierarchically structured aerogels exhibit a tenfold enhancement in gravimetric capacitance (∼162 F g-1) relative to salt-free counterparts.

While ASMR holds immense potential for multi-state memory and logic operations, achieving stable performance across a broad range of conditions and realizing diverse multi-state functionalities remain key challenges. Here, we report the demonstration of multi-state ASMR signals in a Fe3GaTe2/InSe/Fe3GaTe2 vdW heterostructure, effectively operating up to 320 K. Intriguingly, the conventional three-state ASMR undergoes a unique temperature-induced shape reversal, which is precisely correlated with the temperature-dependent crossover of the coercive fields of the two Fe3GaTe2 layers. Through adapted measurement configurations, an unconventional four-state ASMR, featuring distinct high, intermediate-1, intermediate-2, and low resistance states, has been obtained, holding significant promise for enhancing multi-state memory density. Crucially, the device exhibits superior signal stability across wide variations in bias current (0.01-100 µA) and magnetic field angle (0°-360°). Programmable prototype devices demonstrating highly distinguishable states are also presented. The junction resistance of our devices is only a few kiloohms owing to the perfect Fermi level alignment between Fe3GaTe2 and InSe, making them highly compatible with complementary metal-oxide-semiconductor circuits.

Within this structure, the rigid polystyrene (PS) segments immobilize the phosphors and facilitate charge-transfer-mediated OURTP, resulting in high phosphorescence efficiency (Φ = 54.9%, τ = 6.26 s). Concurrently, the polyisoprene (PI) segment ensures outstanding elasticity, endowing the material with ultra-stretchability (2380.5% strain) and fatigue resistance (withstanding 600% strain over 40 cycles).

Although aqueous tin-air batteries (SnABs) offer high theoretical energy density and intrinsic safety, their commercialization faces significant challenges due to high charging overpotential and limited cycle life, primarily caused by sluggish oxygen evolution reaction (OER) kinetics. Here, a hydrogen-aided Sn-air battery (Sn-HAB) is reported, which replaces the sluggish OER with an efficient hydrogen oxidation reaction (HOR) at the cathode during charging, substantially reducing the overpotential. Moreover, a tinophilic brass mesh (BM) substrate is introduced to regulate Sn deposition, enabling a dense and dendrite-free morphology at 100 mA cm-2. As a result, the Sn-HAB operates from 0 to 1000 mA cm- 2, achieving a charging voltage of 1.0 V (versus 2.5 V for SnABs at 100 mA cm- 2) and a cycle life exceeding 900 cycles-nearly 20 times longer than conventional SnABs. An anode-free (without bulk Sn) configuration maintains stable operation for over 800 cycles, and ampere-hour-level cells demonstrate scalability. This work overcomes the rate and efficiency limitations of SnABs, establishing a pathway toward safe, low-cost aqueous energy storage systems.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73309"},"PeriodicalIF":26.8,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147830994","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}

Conventional research primarily elucidates the mechanism through which materials facilitate bone formation by initially modulating macrophages and subsequently encouraging the osteogenic differentiation of stem cells, while largely overlooking the proactive regulatory influence of stem cells on immune cells. Consequently, investigating the capacity of materials to concurrently attract stem cells and modulate innate immune infiltration, while establishing a tissue microenvironment response mechanism, holds substantial importance for the development of next-generation tissue regeneration materials. This study introduces a sea urchin-inspired immune instructional ionic flux (SUIF) platform, characterized by a radial mesoporous structure that employs B─O bond dissociation/dissolution rates and Sr2 + slow-release mechanisms to create a \"fast-slow biphasic\" ionic flow release, thereby establishing a dynamic alkaline ionic flow microenvironment. Within this microenvironment, 5B5Sr-SUIF recruits MSCs and stimulates MSCs to enhance the expression of miR-466m-5p, thereby obstructing the nuclear translocation of NF-κB in macrophages.

Through DFT calculations and transition-state analysis, we demonstrate that doping with P and Se stabilizes the Cu3 clusters, enhances *CO adsorption, and lowers the energy barrier for the rate-determining *CO + *CHO → *COCHO C─C coupling step to 0.84 and 0.92 eV, respectively. Thermodynamic analysis reveals a preference for ethylene formation over ethanol, with overpotentials as low as 0.33 and 0.10 V for P- and Se-doped systems. Electronic structure analysis shows that first-shell substitution with P or Se creates charge-asymmetric sites, strengthens *CO and *CHO binding, and shifts antibonding Cu─CO states to higher energies, thereby promoting efficient C─C coupling. Electrochemically, the Se-modified catalyst delivers a remarkable ethylene Faradaic efficiency of ∼54% at 250 mA cm-2, and maintains stable performance for 30 h under flow-cell conditions.

This approach constructs silylated carbon dots (Si-CDs) with dual-emission centers covalently locked within a rigid silica matrix. The aminosilane precursor serves as a multifunctional building block, simultaneously acting as the carbon source, electron donor, and molecular bridge, which synergistically enhances intersystem crossing while effectively suppressing non-radiative decay. The resulting ultra-small nanoparticles (7-9 nm) exhibit exceptional aqueous RTP performance, including a long lifetime of 859 ms and a high quantum yield of 29.3%. More importantly, we pioneer the concept of programmable time-dependent phosphorescence (TDP), enabling on-demand, dynamic color evolution (e.g., from red to blue) through precise kinetic control. This intelligent temporal color coding, attributed to the synergy between charge-transfer modulation and matrix confinement, opens a new dimension for optical information security.

However, their performance, particularly at high electrode loading, is fundamentally constrained by insufficient electronic conduction-an intrinsic but largely overlooked limitation. Here, we develop a crystallinity-engineered, highly conductive 3D graphitic carbon tube grid (3D-GCTG) using a 3D nickel nanorod grid (3D-NiNRG) as both structural template and catalytic framework. A central advance lies in elucidating and resolving structural collapse and granulation in 3D-NiNRG during catalytic graphitization, enabling a fully interconnected, well-graphitized carbon network with a predefined 3D microstructure. A direct comparison between two carbon tube grids with identical structures and thicknesses but different crystallinities unambiguously reveals the crystallinity-enabled enhancement in frequency response. This synergistic ion-electron transport allows the 3D-GCTG to function as a load-tolerant electrode, effectively decoupling areal capacitance from phase angle. In a two-electrode configuration, the 3D-GCTG maintains a phase angle below -80° at 120 Hz even at 40 µm, delivering a high areal capacitance of 3.77 mF cm-2, a 3.6-fold improvement over the previously reported non-graphitized counterpart.
