Thus, the discovery of non-eluting polymers that immobilize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) upon contact provides an opportunity to develop new coating materials for better infection control. Here, virion-binding polymers are discovered from an existing monomer library via experimental high-throughput screening. Among them, poly([2-diethylamino] ethyl acrylate) (pDEAEA) demonstrates dual functions: binding virions strongly and its speed to inactivate adsorbed SARS-CoV-2. Computational models are built based on the experimental screening data. Polymers that are predicted to be pro-adsorption by the virtual screening are poly(1-{4-[5-(4-methoxyphenyl)-1H-pyrazol-3-yl]piperidin-1-yl}prop-2-en-1-one) (pMPPPP), poly(1-(6-isobutyloctahydropyrrolo[3,4-d]azepin-2[1H]-yl)-2-methylprop-2-en-1-one) (piBOHPAMP), and poly(N-(3-((1-benzylpiperidin-4-yl)oxy)propyl)acrylamide) (pBPOPAm), and these are found to adsorb virions. However, due to limitations in the diversity of structures in the training set, the computational models are unable to predict the adsorption of virions for all polymer structures. Summarily, these findings indicate the utility of the methodology to identify coating polymers that effectively immobilize SARS-CoV-2, with potential practical applications (e.g., water and air filtration).","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"53 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225987","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}

However, many passivation techniques in solar cells involve high temperatures and cost. Here, we report a low-cost and easy-to-implement sulfurization treatment as a surface passivation strategy. By treating p-type c-Si (p-Si) wafers with (NH4)2S solution, sulfur can be introduced onto the surface and passivate the dangling bonds by forming an Si–S bond. Sulfurization also contributes to a higher negative fixed charge at the p-Si/Al2O3 interface and, thus, better field-effect passivation. Due to the improved passivation, sulfurization effectively enhances hole selectivity, evidenced by the substantially improved open-circuit voltage and efficiency of solar cells. Eventually, by employing sulfurization in hole-selective contacts, remarkable efficiencies of 19.85% and 22.01% are attained for NiOx- and MoOx-based passivating contact c-Si solar cells, respectively. Our work highlights a promising sulfurization strategy to enhance surface passivation and hole selectivity for dopant-free c-Si solar cells.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"7 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225990","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}

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}

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.

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.

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.

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}
