The localized surface plasmon resonance (LSPR) of Ag NPs not only promotes the deoxygenation of GO to form a superhydrophobic surface but also repairs the conjugated structure of GO via hot electron transfer, reducing its defect density by 21%. The resulting Ag NPs@rGO composite exhibits strong solar‐spectrum absorption (93.8%) and high photothermal conversion efficiency (89.7%). When coated on a polyurethane (PU) sponge, the material rapidly heats to 81°C within 60 s under 1 sun irradiation, significantly reducing the viscosity of crude oil and achieving an adsorption capacity of 47.2 g/g, six times higher than that of conventional carbon‐based sponges. Remarkably, the sponge maintains stable adsorption performance over 36 absorption‐desorption cycles and demonstrates exceptional chemical/mechanical durability.

Unfortunately, inflammation remains poorly controlled and prone to relapse, even after removing the initial plaque biofilm. The unique metabolic properties of mitochondria in the periodontal microenvironment provide a promising target for novel therapeutic strategies against periodontitis. Here, we integrate metabolomics and network biology to elucidate the potential role of nuclear factor E2‐related factor 2/mitochondrial transcription factor (Nrf2/TFAM) in regulating mitochondrial metabolism in periodontitis. Based on this discovery, it is crucial to develop an innovative nanomedicine capable of effectively modulating the mitochondrial metabolism in periodontitis. Recently, itaconate (ITA), a key metabolite linking mitochondrial metabolism and inflammation, has emerged as a powerhouse in regulating immunity through Nrf2; however, its limited permeability hinders its application in biological systems. Therefore, we synthesize ITA‐based nano cocktail (INC) with cell permeability and improved biological functions. At the cellular level, INC activates Nrf2/TFAM to remodel mitochondrial metabolism and regulate macrophage immune homeostasis. In mouse models of periodontitis, INC successfully reprograms mitochondrial metabolism within the gingiva, leading to an improved inflammatory microenvironment. Our study elucidates the role of INC in modulating mitochondrial metabolism, thereby offering an innovative therapeutic strategy for the management of periodontitis and other clinical conditions resulting from mitochondrial abnormalities.","PeriodicalId":510850,"journal":{"name":"SmartMat","volume":"6 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/smm2.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous research has predominantly focused on modulating the physical properties of the channel materials to enhance synaptic performance, the role of ion dynamics in influencing device characteristics remains underexplored. Effective regulation of ion dynamics is crucial for improving state retention and achieving long‐term plasticity (LTP) in these devices. In this study, we propose a strategy to modulate the interactions between polymer semiconductors and ions in solid‐electrolyte‐based artificial synapses. Our findings indicate that the interplay between semiconductors and doping counterions significantly influences ion transport dynamics, thereby affecting the electrochemical doping and dedoping processes in OECTs. Notably, by suppressing the dedoping process, we achieved enhanced synaptic performances, with devices retaining 64% of the peak current after a retention time of 1000 s. Through the judicious selection of anions and optimization of their interactions with polymer semiconductors, we effectively controlled the dedoping process in OECTs, leading to improved state retention. These insights provide a novel perspective on tuning ion‐polymer semiconductor interactions for the development of high‐performance synaptic devices, advancing neuromorphic computing applications.","PeriodicalId":510850,"journal":{"name":"SmartMat","volume":"6 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/smm2.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147912070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, in contrast, we introduce a hydrophilic glycol chain‐modified photocrosslinker (DtFGDA) for the direct photolithography process and blend it with various representative hydrophobic conjugated polymers. The precise patterning of blended films by direct photolithography is achieved while tremendous enhancements of OECTs performance are attained, with maximum six orders of magnitude higher transconductance, significantly decreased hysteresis, and lower threshold voltage. Through spectroelectrochemical characterization, surprisingly, no obvious variations in polaron absorption peaks are observed in all conjugated polymer/crosslinker blends. An ionic‐electronic separated conduction mechanism, which is never reported in OECTs before, is further proposed based on the characterization of the transmission electron microscope, wherein ions primarily migrate within the crosslinker while holes transport within the semiconducting polymer.

Steering COR selectivity toward specific types of C 2+ products, such as liquid products with high energy density, remains a challenge. In this study, we developed a Cu/Zn bimetallic catalyst composite and demonstrated enhanced selectivity toward liquid products as compared to reference CuO and Cu‐based catalysts, approaching 60% at a high current density of 300 mA/cm 2 . Our investigation highlights that the introduction of Zn promoted the emergence of a Cu/Zn heterojunction interface during COR.
