The developed SnO₂/NiO/rGO sensor towards 50 ​ppm NO₂ gas demonstrates an excellent gas-sensing response of 14.8 ​at 23 ​°C, which is 3.03 times that of NiO/rGO sensor (4.89) and 6.49 times that of NiO sensor (2.28), respectively. The developed SnO₂/NiO/rGO sensor exhibits faster response/recovery speed (12.7/32.8 ​s @5 ​ppm), with extra-low theoretical detection limit of 0.15 ​ppb at room temperature. More fascinatingly, our sensors indicate great sensitivity, outstanding repeatability and long-term stability for longer than 7 weeks. Additionally, it also suggests that 1 ​°C and 1 % relative humidity have the same effect on the SnO₂/NiO/rGO sensor signal as approximately 13 ​ppb and 7.0 ​ppb NO₂ gas change, respectively. Such excellent properties are mainly attributed to the large surface-to-volume ratio, which provides active sites to NO₂ gas spread, adsorption and diffusion on material surface in redox reaction. Moreover, the ternary heterojunctions formed by NiO, rGO and SnO₂ may serve as highly conductive channels to accelerate carrier transfer and abundant oxygen vacancies to reduce the adsorption energy for O₂ and NO₂ gas, thus further improving performance of the sensors.</div></div>","PeriodicalId":33573,"journal":{"name":"Nano Materials Science","volume":"8 1","pages":"Pages 36-48"},"PeriodicalIF":17.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146057509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional CSP entails the addition of liquid phases as a solvent to achieve material densification through the dissolution-precipitation mechanism. However, it is difficult to realize for materials with low solubility. To address this challenge, a universal cold sintering method without the addition of liquid phases has been proposed in this work. The addition of a special polyester-polymer assisted the densification of insoluble ceramics, and hydroxyapatite (HA) and Al₂O₃ were successfully sintered below 100 ​°C, achieving 95–100 ​% densities in a short time (5–20 ​min). This achievement can be attributed to the low glass transition temperature and the abundance of active sites (C=O) of the polyester-polymer. The denser ceramics exhibited enhanced mechanical properties, with the compression strength of polymer-assisted CSP HA increasing by 147.3 ​% compared to the nanoparticles. Additionally, serving as an advanced bone substitute material, HA underwent quantitative analysis using the CCK-8 method and assessed the impact of polymer presence on cell proliferation and cytotoxicity.

However, the emission full width at half maximum (FWHM) of CIS-based QDs typically extends to ∼140 ​nm, fundamentally limiting their use in high-color-purity light emitting. Herein, we report the rationally-designed CIS QDs with high efficiency and narrowband emission by chemical stoichiometry and gradient shell engineering, based on precisely controlling the dynamic growth and stoichiometric ratio. It is found that the accurate control on the growth kinetics and stoichiometry during the nucleation process of CIS QDs could enhance the crystallinity through gradual and organized crystalline growth, which effectively mitigates the formation of In_Cu substitutional and Cu vacancies, thus suppressing the defect emission. Furthermore, the introduced InS_x/Zn_xGa_1-xS gradient shell on the surface of QDs cores could reduce the strain within interface, thereby eliminating the non-radiative recombination caused by the surface defects resulted from interface strain. As a result, a remarkable PLQY of 89% is achieved for the QDs.
