Replacing OER with low‐potential organic oxidation provides an effective route to reduce cell voltage while enabling value‐added chemical synthesis. Here, a nanostructured Au electrocatalyst is developed from recycled electronic waste via a corrosion‐template–assisted electrodeposition strategy. Co(OH) <jats:sub>2</jats:sub> nanoarrays grown on nickel foam act as a sacrificial template to regulate galvanic displacement between chloride‐coordinated Au(III) species and metallic Ni, inducing polycrystalline Au nucleation with tailored surface structures. Subsequent electrodeposition precisely controls Au size and dispersion, resulting in a substantially enlarged electrochemically active surface area. In alkaline media, the Au electrode selectively drives aldehyde oxidation of 5‐hydroxymethylfurfural to 5‐hydroxymethyl‐2‐furoic acid at potentials well below those required for OER, while enabling concurrent anodic hydrogen evolution and stable low‐voltage bipolar hydrogen production. In a flow‐electrolysis configuration, current densities of ∼0.6 A cm <jats:sup>−2</jats:sup> are sustained at a low cell voltage of ∼1.2 V for over 200 h. By decoupling low‐potential aldehyde oxidation from high‐potential deep oxidation in a tandem electrolyzer, stepwise electrochemical upgrading from HMF to FDCA is achieved with reduced overall energy input.

Although atomistic calculations can evaluate migration barriers directly, simple descriptors can greatly facilitate screening large materials spaces and gaining mechanistic insight. However, existing descriptors often show limited transferability across mobile‐ion chemistries and material classes. Here, we generate a diverse dataset of ion‐migration barriers spanning Li‐, Na‐, K‐, and Mg‐ion conductors across oxides, sulfides, and halides, and use it to systematically benchmark descriptors. From this analysis, we devise distance contraction, ∆ <jats:italic>d</jats:italic> , a simple local geometric descriptor that measures the largest contraction of mobile‐ion–neighbor distances relative to their equilibrium values along a migration pathway. This quantity captures the dominant short‐range repulsion penalty associated with ion migration and consistently distinguishes low‐ from high‐barrier pathways across chemistries. Using ∆ <jats:italic>d</jats:italic> in a high‐throughput screening workflow, we recover many known fast‐ion conductors and identify previously unexplored candidates, with fast‐ion transport validated by nudged elastic band calculations and ab initio molecular dynamics simulations.

Inspired by the active‐site chemistry of native GPX, we designed dichalcogenide‐hybrid mesoporous silica nanoparticles (MSNs) as inorganic–organic nanozymes with tunable sulfur and selenium environments. Structure–activity analysis showed that GPX‐like performance is governed by chalcogen composition, chalcogen density, and spatial proximity of S/Se within the framework, which together regulate reversible disulfide/diselenide redox cycling and substrate access. Among the materials tested, the diselenide–hybrid framework exhibited the highest activity, with improved selectivity and biocompatibility relative to the disulfide‐hybrid analogue, and conventional metal‐based GPX mimics. Mechanistic studies indicated efficient glutathione‐dependent detoxification of peroxides and lipid peroxides through catalytically active chalcogen intermediates. In vivo, the optimized diselenide‐hybrid material protected against acetaminophen‐induced and rifampicin‐induced liver injury, reduced oxidative stress and inflammation, restored antioxidant capacity, and improved survival. It also alleviated steatosis and metabolic dysfunction in metabolic dysfunction‐associated steatotic liver disease (MASLD) models. These findings establish dichalcogenide–hybrid frameworks as effective GPX‐like nanozymes and a promising platform for the treatment of oxidative stress‐associated liver diseases.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"89 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218753","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}

However, the role of these specific vibrations, commonly known as chiral phonons, in driving ultrafast spin dynamics has not yet been explored experimentally. Here, using broadband terahertz emission spectroscopy, we demonstrate that the non‐magnetic ferroelectric generates signals consistent with a ultrafast spin current after excitation with an ultrafast laser pulse, which we attribute to a chiral phonon–induced spin Seebeck effect. We suggest that the transient heating creates an non‐equilibrium phonon distribution, resulting in a net angular momentum and magnetization perpendicular to the thermal gradient, which is converted into a terahertz electromagnetic pulse via an inverse spin‐Hall effect in a thin metal overlayer. The emitted field reverses sign upon flipping the sample orientation or replacing Pt with W, consistent with spin‐current generation. Polarization‐resolved measurements reveal controllable terahertz ellipticity, indicating an additional polarization‐dependent ultrafast response. Our results establish chiral phonons as a route for generating ultrafast spin currents in non‐magnetic materials as well as providing a pathway toward terahertz sources with switchable handedness.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"88 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218755","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}

In this study, steady‐state and transient absorption spectroscopy are employed to disentangle the spectral signatures and excited‐state dynamics of interacting and noninteracting Y6 in solution and thin films. By controlling aggregation in dilute solution, we identify localized Frenkel‐type excitons (LE) on noninteracting Y6 and aggregate excitons (AE) on intermolecular interacting Y6. The AEs exhibit strongly fluence‐dependent lifetimes (30–200 ps) governed by singlet–singlet annihilation, whereas localized excitons decay monoexponentially on a nanosecond timescale. Furthermore, long‐lived polaronic states are observed to form on aggregated Y6 within tens of picoseconds and persist into the nanosecond regime. Comparison with thin‐film measurements reveals similar processes with an additional ultrafast energy transfer from noninteracting chromophores to aggregated domains. These results establish a consistent framework for assigning transient absorption features in Y6 and suggest that, in neat films of Y6, the pairwise formation of polarons arises from an Onsager‐like autoionization process of delocalized excitons in domains of interacting Y6 with moderate yield. This provides central insight into charge‐generation mechanisms in Y6‐based photovoltaic systems.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"44 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218773","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}

TVP of native proteins such as collagen is attractive because it preserves native bioactive motifs that regulate cell–matrix signaling. However, direct TVP of collagen remains challenging because dityrosine crosslinking, driven by visible‐light‐activated Ru(II)bpy <jats:sub>3</jats:sub> <jats:sup>2+</jats:sup> /sodium persulfate (SPS), lacks an effective inhibitory mechanism. This results in near‐immediate crosslinking upon light exposure, leading to an insufficient nonlinear threshold response that fails to suppress background curing. Here, we introduce vitamin C (L‐ascorbic acid) as a biocompatible redox regulator to overcome this limitation. We demonstrated that vitamin C established a photo‐redox threshold by suppressing Ru(III) accumulation and scavenging persulfate radicals within the Ru/SPS system, thereby delaying dityrosine crosslinking until vitamin C depletion. This threshold generated the nonlinear response required for TVP, enabling high‐fidelity volumetric printing of collagen. Post‐printing construct densification (∼53% shrinkage) further improved feature resolution (80 µm positive; 120 µm negative) and yielded mechanically stable and highly stretchable hydrogels (up to 180% strain). Collagen resin with vitamin C supported both cell seeding post‐printing and cell‐laden printing with high cell density and viability, enabling the rapid biofabrication of cell‐instructive 3D microenvironments.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"7 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218745","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}

Fundamentally, HER is a parasitic cathodic reaction competing with Mn electrodeposition and may accompany Mn corrosion. Its kinetics are influenced by the interfacial water environment within the electric double layer (EDL).

Consequently, the Mn anode exhibits a markedly enhanced Coulombic efficiency of 93%.
