However, the large bandgap, inherent brittleness, poor environmental stability, and weak interfacial adhesion interaction between perovskites and substrates hinder the application of near-infrared (NIR) wearable devices. Herein, a universal strategy to enhance the performance and mechanical stability of flexible perovskite NIR photodetector arrays is demonstrated through a combination of mussel-inspired self-assembled monolayer (SAM) bridging interface and precise modulation of the nano-array size, which enables to significantly increase interfacial adhesion, crystallinity, crystallographic orientation, and reduce mechanical stresses of perovskite single-crystal arrays. Moreover, inserting paddle-wheel metal–organic cluster ligands lead to an unprecedented small bandgap of 1.04 eV, enhanced lattice rigidity, and environmental stability for 2D perovskite. The flexible perovskite NIR photodetector arrays with superior mechanical robustness and record NIR performance are revealed with a maximum response wavelength of 1050 nm, a responsivity of 1.66 A W−1, detectivity of 6.19 × 1012 Jones, high fidelity imaging, and extra-long environmental stability.

Current methods such as natural decomposition, composting, and incineration are limited by significant carbon dioxide emissions and resource waste. Here, an efficient electrocatalytic conversion approach is presented to transform PLA waste into high-value chemicals, particularly potassium acetate (AA-K). By combining experimental and theoretical calculation, a high-performance catalyst Ni(Co)OOH is developed, which exhibits a current density of 403 mA cm⁻2 at 1.40 V (vs RHE) with 96% Faraday efficiency for AA-K in the electrooxidation of potassium lactate (LA-K, the product of PLA degradation in KOH). Through in situ spectroscopy techniques and density functional theory calculations, the structural regulation of the catalyst, and reaction pathways of the electrooxidation are elucidated. Further experiments demonstrate the superior catalytic performance of the Ni(Co)OOH catalyst in an industrial-scale tandem system. In 2 h of electrolysis, 320 g of PLA waste produces 232 L of H₂, yielding 1200 g of AA-K with 97% purity after neutralization and drying. The system demonstrates high conversion efficiency (approaching 97%) for diverse real PLA waste forms, including powder, cups, fibers, and cloth. This research provides a scalable and sustainable approach for PLA waste upcycling.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"3 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401637","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 molecularly functionalized cellulose hydrogel, exemplifying our approach, shows favorable water uptake of 0.86–1.32 g g−1 at 15–30% relative humidity (RH), along with efficient desorption, releasing 95% of captured water at 60 °C.

Here, the grid-like multilocular spheres derived from TCOP with abundant redox active sites and unique structures are fabricated via a molecular twist-induced regulation strategy, of which the number and size of cavities can be finely modulated by changing the conformers of the twisted unit and the Ostwald ripening time. The unique structure of the as-fabricated TCOP results in unprecedented high specific capacitance (8412 F g−1 at 1 A g−1) and enables the as-assembled supercapacitor with an ultra-high energy density of 675 Wh kg−1 in redox-active electrolyte (KI-mixed H2SO4), much better than all reported aqueous supercapacitors thus far. It is found that the high electro-activity is due to the synergistic effect of the enhanced accessibility of active sites and the enhanced interaction of the abundant active sites with the redox-active electrolytes.

The hydrogel is composed of Au─MoS2─phenylboronic acid nanozyme and insulin-loaded nitroimidazole-modified sodium alginate hypoxia-sensitive microcapsules and penylboronic-acid-modified chitosan. It utilizes glucose as a sacrificial agent to generate antibacterial reactive oxygen species by recognizing the hyperglycemia environment, and releasing insulin for blood glucose regulation for up to 12 h with the help of the enzyme-like catalysis-generated hypoxia environment. In a normoglycemia environment, the hydrogel switches the enzyme-like activity to supply oxygen, inhibiting further insulin release. The hydrogel achieves ≈3 times the wound recovery rate of commercial dressings through blood glucose regulation and improved wound microenvironment.

Further, these sensors often struggle to distinguish between isomers and homologs, as these compounds usually have similar physical and chemical properties, yielding nearly identical sensor responses. Even the mammalian olfactory systems consisting of a large variety of receptor cells and efficient neuron networks sometimes fail in this task. The bottleneck stems from the inability to extract the fingerprints of these compounds and the inefficiency of signal processing. To address these limitations, a material-device-algorithm co-design strategy is proposed that integrates an organic field-effect transistor (OFET) array with in-sensor reservoir computing (RC) and the k-nearest neighbors (KNN) algorithm. Organic semiconductors diversify responses to different gases, while RC efficiently extracts spatiotemporal features with lower training costs and reduced energy overhead. This synergy achieves 100% classification accuracy for eight gases and 99.04% accuracy for a library of 26 gases, including mixtures, isomers, and homologs—among the highest reported accuracies.

Here, a simple strategy is introduced that utilizes charge repulsion between graphene oxide (GO) and engineered bacteria to induce liquid crystal formation, enabling their layer-by-layer self-assembly on a polyethersulfone membrane. The interlayer pressure flattens the bacteria, removing interlayer water and forming a densely packed structure. This compression decreases the spacing between functional groups, leading to a robust hydrogen bonding network and a significant enhancement in mechanical properties (12.42 times tensile strength increase). Notably, the pressure preserves the activity of the super uranyl-binding protein of engineered bacteria, which selectively coordinates with uranyl (UO22+) through high-affinity coordination bonds, enabling recognition and sieving of target ions. The membrane demonstrates near 100% rejection of UO22+, K/U, and V/U selectivity of ≈140 and ≈40, respectively, while maintaining long-term stability.
