The engineered binding protein β-wrapin AS69 binds monomers of Parkinson-disease-associated α-synuclein (αS), yet achieves inhibition at substoichiometric concentration. The substoichiometric activity was not attributed to the binding protein per se, but to its 1:1 complex with αS, in which AS69 sequesters αS residues 30–60 into a globular protein fold, whereas other αS parts remain intrinsically disordered regions (IDRs). Here, we investigate AS69-αS fusion constructs that form the AS69:αS complex by intramolecular folding and expose different IDRs. We find that not only the globular part of the complex but also αS IDRs are critical for substoichiometric inhibition, which is achieved by interference with primary and secondary fibril nucleation. The effects in vitro are reproduced in cellular seeding assays, indicating that secondary nucleation drives seeding in aggregate biosensing.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"10 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226024","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, the technoeconomic prospects of comprehensive conversion of hydrogen to ammonia and ammonia to hydrogen (H2-NH3-H2) are unclear, and the approach to ammonia-to-hydrogen conversion has not yet reached the full commercialization stage. In this work, we perform a technoeconomic analysis of a H2-NH3-H2 conversion system, including synthesis, storage and transportation, and ammonia-to-hydrogen conversion, where we particularly compared thermal ammonia cracking with ammonia electrolysis. We find that ammonia electrolysis has a significant economic advantage thanks to its low energy consumption and capital cost. With this as motivation, we develop an energy-efficient and durable ammonia electrolyzer with an energy consumption of 0.84 kWh Nm−3 H2 and a continuous operation for 317 h at 100 mA cm−2. In addition, we also innovate a tandem cell to produce hydrogen without any electric power supply by coupling fuel-cell and electrolysis technologies.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"7 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226025","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}

The development of non-invasive multi-modality probes targeting PE for apoptosis detection holds great promise. Here, we develop a dual-modality imaging probe, duramycin-Fluc-AuNRs (DFA), for detecting apoptosis in tumor cells. DFA is created by linking duramycin peptide and firefly luciferase (Fluc) recombinant protein to gold nanorods (AuNRs). Duramycin exhibits high affinity for PE, while Fluc produces a robust bioluminescence signal, and AuNRs enhance imaging resolution through photoacoustic conversion. The DFA probe demonstrates low toxicity in both cells and mice, showcasing its potential for in vivo applications. In A549 and 4T1 cell lines, the bioluminescence signal of the DFA probe increases with the degree of doxorubicin (Dox)-induced apoptosis. At the mouse level, mice with Dox-triggered apoptosis exhibit higher bioluminescence and photoacoustic imaging signals. Thus, this dual-modality bioluminescence/photoacoustic imaging platform holds significant potential for detecting cellular apoptosis and providing high-performance imaging information.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"2 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226026","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}

Nevertheless, the development of high-performance hydrogels continues to be a significant challenge due to the inherent trade-off between conductivity and deformation adaptability. Here, a novel strategy is demonstrated for the preparation of intrinsically conductive reticulated polymer-based hydrogels (allylated hydroxyethyl cellulose-PEDOT:PSS/PAM hydrogel [AHEC-PP/PAM]) with mechanical robustness and perceptual sensitivity. The conductive reticulated component, AHEC-PP, is obtained by an ingenious polymerization involving AHEC and EDOT and demonstrates favorable dispersion and stability, with the treatment of H2SO4 and the charge regulation of PSS. The AHEC-PP/PAM hydrogel has a tensile strength of 0.69 MPa, a fracture strain of 1,273%, a broad sensing range, and a high gauge factor of 7.86. The synergistic performance enables integration into smart wearable electronic devices for the detection of motion signals, electronic skin, and advanced human-machine interaction.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"11 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226027","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 these materials generally have lower latent heat than materials with a solid-to-liquid phase transformation, their significantly higher thermal conductivity enables rapid thermal charging/discharging. Here, we show that this property makes them particularly promising for thermal energy storage applications requiring highly dynamic operation. A numerical analysis (using an experimentally validated numerical model) has revealed that some materials with solid-to-solid phase transformations offer an excellent capacity-power trade-off for thermal energy storage applications compared to the corresponding conventional phase change materials. While most conventional phase change materials generally offer higher thermal capacity due to larger latent heat, some metallic materials with solid-state transformation (e.g., Ni-Ti-based alloys, Mn-Co-Ga-B alloys) exhibit up to 10 times higher thermal output powers. These results highlight a significant potential of caloric solid-state materials to outperform traditional latent thermal storage systems for certain applications.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"451 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226028","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, their feasibility has not been conclusively demonstrated, partly due to inconsistent preparation and benchmarking. Here, we verify the catalytic activity of lanthanum single atoms for pollutant degradation by a rigorous benchmarking protocol that considers the contributions of adsorption, catalytic activity of supports, and leached ions. The reaction rate constant increases linearly with lanthanum loading up to 9 wt %, illustrating the viability of synchronously realizing high specific activity and maximized atom utilization. In addition, we show that the synergetic activation of peroxymonosulfate (PMS) and oxygen to produce multiple reactive oxygen species (ROS) is responsible for the catalytic performance, revealing the previously ignored contributions of air in catalytic systems. We anticipate that this protocol will aid in the development of SACs to realize their full prospects.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"28 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225804","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}
