We introduce a droplet memristor in which applied voltage drives a non-conductive liquid crystal droplet to penetrate into a microwell, blocking the ionic conduction path and increasing the resistance. Our system exhibits switchable excitatory and inhibitory features, modulated by altering the polarity of the ionic surfactants at the liquid-liquid interface. We find that memory effects are proportional to the voltage amplitude and inversely proportional to the scanning frequency, consistent with predictions by Newton’s dynamic theory. We emulate adaptive learning akin to biological synapses and demonstrate that low-temperature-induced phase changes in droplets reduce the handwriting recognition accuracy in droplet artificial neuron networks, promising in-sensing computing capabilities. The droplet memristor can benefit from the diverse liquid properties to extend the functionalities and applications in future neuromorphic computing.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"3 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While extensive studies on energy transfer dynamics within individual light-harvesting complexes (LHCs) have been conducted, the inter-protein transfers crucial for understanding the overall efficiency of these systems have remained experimentally elusive. This arises mainly because the spectral signatures of the subunits are often remarkably similar, complicating the identification of energy transfer pathways among them. This study bridges this gap by utilizing ultrafast transient absorption spectroscopy, under conditions with and without singlet-singlet annihilation, on the photosystem II (PSII) LHCII-CP24-CP29 subcomplex and on its constituents. Our findings reveal rapid equilibration within monomeric complexes, contrasted by six-times slower equilibration in the LHCII trimer and eight-times slower equilibration in the LHCII-CP24-CP29 subcomplex, highlighting the inter-complex energy transfer as the rate-limiting step in excitation delivery to the RC.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"2 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we develop a framework utilizing deep learning to analyze vast molecular dynamics (MD) data to reveal the molecular-level transport properties in electrolyte films. This framework contains physical feature analysis and selection based on MD simulations, surrogate model training, structure-transport relationship analysis, and structure discovery. This framework is then applied to explore oxygen transport in fuel cells, which allows the transport properties and their relationships to the structural characteristics of electrolyte films to be revealed, and thus, the critical features limiting oxygen transport are identified. Accordingly, increasing the catalyst surface hydrophilicity and suppressing the electrolyte film density fluctuation are favorable for oxygen transport. Moreover, this framework is transferable to revealing similar molecular-level transport phenomena in electrolyte films that widely exist in other electrochemical energy devices.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"2 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinically, low drug-delivery efficiency, frequent administration, hormone complications, and antibiotic resistance remain the major unsolved challenges. Here, we introduce a chlorogenic acid (CGA)-conjugated CL material based on gelatin methacrylate via cryogelation(cGelMA/CGA-CL) to strengthen the prevention and treatment of BK. The cGelMA/CGA-CL features a highly moist, macroporous, adjustable structure for sustained release of CGA and is favorably biocompatible to cells, providing antimicrobial protection against opportunistic pathogens and inhibiting excessive ocular inflammatory responses through the JAK2-STAT1/STAT2 signaling pathway. Furthermore, the cGelMA/CGA-CL effectively alleviates the symptoms of BK with immunoregulation of macrophage recruitment and anti-inflammatory factor release in a mouse model of BK. The cGelMA/CGA-CL offers a promising candidate for the prevention and treatment of BK, which may significantly reduce the risk of infection for CL wearers.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"21 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toward future energy, we propose this perspective and introduce a groundbreaking paradigm for a versatile energy AI, termed artificial general intelligence for energy (AGIE). AGIE is designed to address a spectrum of energy-related issues with flexibility, drawing upon information such as energy parameters, equipment images, and expert voice feedback. The applications of AGIE are diverse, ranging from energy diagnostics and operational optimization to offering advice on energy policies. By incorporating human-in-the-loop interactions and leveraging domain knowledge, AGIE has the capacity to assimilate the habits of energy users. Through continuous reinforcement learning, it aspires to establish a new paradigm of explainable reasoning, paving the way for the development of credible energy robots with attributes similar to human understanding. We anticipate that AGIE-enabled applications will lead to new approaches in energy usage and the consideration of serious technical and societal challenges ranging from data integration to privacy and security concerns, environmental impacts, and constraints in hardware and software. Addressing these issues is crucial for realizing the full potential of generalist energy intelligence, leading to enhanced energy efficiency and contributing to the resolution of global energy problems.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"45 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we propose a charge replenishment-assisted S-scheme mechanism that combines a compatible host catalyst with a luminescence phosphor semiconductor capable of long-term storage of photogenerated electrons. Stored electrons can replenish the host photocatalyst, depleting the low-oxidizing holes, thus prolonging the charge-separated state. The concept is demonstrated in a core-shell-structured SrGa2O4:Cu2+/g-C3N4 (SGO/CN) photocatalyst, where stored electrons with a lifetime of up to several hours can continuously consume holes in the CN. The well-defined core-shell structure, abundant interfacial Sr-N bonds, and staggered band alignment between SGO and CN are crucial for this S-scheme interfacial charge transfer, which contributes to the enhanced CO2-to-CO transformation activity and selectivity. This S-scheme heterojunction, incorporating a charge-storing material as an excess electron reservoir, offers a promising template for designing efficient photocatalytic systems.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"18 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, we have systematically studied fluorine substitutions in the aromatic side chains of HCl-binding pseudopeptidic cages. Interconnected factors like chloride binding, protonation, lipophilicity, and conformation and diffusiveness of the cages can impact their ability to transport HCl through the aqueous-lipid interphase, as demonstrated by robust experimental (X-ray, nuclear magnetic resonance [NMR], fluorescence) and theoretical results. The fine-tuning of these properties allows the modulation of their pH-dependent cytotoxicity against cancer cells, from essentially non-cytotoxic at pH 7.5 (like the extracellular surroundings of healthy tissues) to highly toxic in slightly acidic microenvironments (like those around solid tumors). Thus, a distal fluorine substitution produces a big impact on the physicochemical and biological properties of the cages, improving their selectivity as potential therapeutic ionophores.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"61 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
