However, they suffer from rapid oxygen activity fading, commonly related to bonding interactions between the transition metals and oxygen, while receiving limited attention on the role of Li ions. Here, we demonstrated the protective role of Li ions in maintaining oxygen orbital symmetry to improve oxygen redox reversibility. The orbital symmetry breaking induced by Li ion migration leads to a disproportionation of oxygen during charging. This results in some oxygen becoming overoxidized and labile, compromising the structure and cycling stability. This mechanism is validated through experiments on P3-Na0.6Li0.2Mn0.8O2 and other layered manganese-based cathodes, as well via dynamic simulations. Finally, employing P2-Na0.75Li0.25Mn0.75O2, we propose a design strategy for stabilizing Li ions via electrostatic field disordering, enhancing the capacity retention over 150 cycles from 46 % to 72 %. The insights open an avenue towards the rational design of high-performance manganese-based cathodes.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, guided by theoretical predictions on the merits of plasmon-coupling metal nanoparticles within dielectric matrices, Rum@pSiO2 nanoreactors, where clustered Ru nanoparticles confined in a porous SiO2 shell, are rationally designed. This architecture features enhanced plasmon-energy harvesting, intensified electromagnetic field confinement, and optimized photothermal management. Consequently, the as-designed Rum@pSiO2-2 nanoreactor achieved a remarkable CH4 production rate of 8.75 mol gRu-1 h-1 with near-100 % selectivity at 250 °C under irradiation in photo-thermal CO2 methanation, surpassing surface-supported Rum/pSiO2 and isolated Ru1@pSiO2 catalysts by 3.2- and 2.6-fold, respectively. Notably, it delivered a CH4 yield of 2.26 L gcat-1 h-1 under natural sunlight, even on a winter day (outdoor temperature: -4-6 °C).

By explicitly incorporating space group symmetry, CrystalFormer greatly reduces the effective complexity of crystal space, which is essential for data-and compute-efficient generative modeling of crystalline materials. Leveraging the prominent discrete and sequential nature of the Wyckoff positions, CrystalFormer learns to generate crystals by directly predicting the species and coordinates of symmetry-inequivalent atoms in the unit cell. We demonstrate the advantages of CrystalFormer in standard tasks such as symmetric structure initialization and element substitution over widely used conventional approaches. Furthermore, we showcase its plug-and-play application to property-guided materials design, highlighting its flexibility. Our analysis reveals that CrystalFormer ingests sensible solid-state chemistry knowledge and heuristics by compressing the material dataset, thus enabling systematic exploration of crystalline materials space. The simplicity, generality, and adaptability of CrystalFormer position it as a promising architecture to be the foundational model of the entire crystalline materials space, heralding a new era in materials discovery and design.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accumulating evidence shows that cancer processes are not only related to genetics and environment but also to chronic stress. For patients with cancer, the disease process induces prolonged psychological and physical stress, including fear and pain, which makes chronic stress common in patients. Chronic stress, in turn, regulates different components of the primary tumor and tumor microenvironment through a wide variety of stress mediators. Furthermore, studies indicate that chronic stress increases tumor burden and mortality in patients with different types of cancer, while the management of chronic stress can alleviate disease burden and extend patient survival. Therefore, a deeper understanding of the role and mechanism of chronic stress in cancer is necessary for developing new strategies for cancer treatment beyond traditional treatment approaches. Herein, we explored the different sources of chronic stress, the molecular mechanisms through which chronic stress affects cancer development and progression, and the stress mediators involved. We discussed the multiple impacts of chronic stress on cancer, as well as the currently available intervention strategies. We also highlighted the prospects and challenges of chronic stress management in the clinical treatment of cancer.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 carried out the vertical observations of aerosols, clouds, and precipitation at the MQ, where the dual-radar active remote sensing technique is integrated with precipitation observation for the first time. It is found from the observational study that during the Indian summer monsoon, aerosols from South Asia have a distinct activation effect on the cloud-precipitation process over the MQ. Under dynamic lifting, the increase in aerosols, which inhibits and delays weak precipitation over the MQ, instead intensifies the development of clouds over the MQ, leading to heavy precipitation on the north slope. The synergy of the MQ thermal-dynamic driving mechanism and the aerosol activation effect can trigger the deep convection in the precipitation process on the north slope of the MQ. Cloud development is more intense with the aerosol activation effect, and the diurnal cycle of convective clouds in the vertical change over the MQ presents a lag response to changing aerosols. From the perspective of climate impact on interannual variations, it can also be found that the frequency of light rain over the MQ present the significantly decreased trend, while the frequency of moderate to heavy precipitation on the north slope has a significantly increased trend, revealing the differentiated changes in the precipitation on the south and north slopes of the MQ under the influence of the aerosol activation effect on the cloud-precipitation process.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
