2024年8月2日 · FTIR, EDS, SEM, and XRD analyses show that the synthesised CZF@CQDs photocatalyst has been successfully made, and TGA analysis demonstrates the high stability of the nanocomposite at high ...

2024年4月1日 · SEM allows researchers to investigate the morphology and structural features of CQDs with high resolution [172]. SEM characterization of CQDs involves scanning a focused electron beam across the sample's surface and detecting the associated signals, which include secondary electrons, backscattered electrons, and distinctive X-rays, to provide a ...

2023年11月18日 · In this paper, we introduce eleven PbS CQD samples: a PbS CQD with d ~ 3.6 nm (sample A), eight CQDs with d ~ 4.8 nm (samples B, D, F, G, H, I, J, and K), and two CQDs with d ~ 8.7 nm (samples...

2 天之前 · The SEM-EDX analysis confirmed the presence of N elements in CQDs, while FTIR detected C N band, both of which contributed to the excellent fluorescence properties of CQDs. Similarly, Smrithi et al. [ 111 , 112 ] employed HT processes to synthesize CQDs from Cucurbita pepo with a QY of 12.19 %.

2022年1月20日 · The SEM images of date palm leaf-derived hydrochar shown their sphere-shaped nature with 0.5–2 µm diameter. We investigated the cytotoxic behavior of CQDs using human mesenchymal stem cells (hMSCs) as an in vitro model with MTT assay and acridine orange/ethidium bromide (AO/EB) dual staining.

2 天之前 · CQDs controllably release amine monomers at the reaction interface, enabling the COF layer to nucleate and grow slowly, resulting in a highly ordered and uniform membrane structure. The resulting COF‒membrane composite membranes, ... (SEM, Hitachi S-4500) and atomic force microscopy (AFM, Bruker Multimode 8) were used to characterize the ...

2024年11月15日 · In the present investigation, novel TiO 2 /CQDs nanocomposites were effectively synthesized utilizing carbon quantum dots (CQDs) sourced from readily available four varieties of waste banana peels as a precursor characterized by distinct quantum yields.

In this work, we applied ε-poly (L-lysine) carbon quantum dots (PL-CQDs) aqueous solution as a potential root canal flushing agent to study its inhibitory effect on planktonic E. faecalis and their biofilms and performed flushing tests on isolated teeth.

通过扫描电子显微镜（sem），透射电子显微镜（tem），傅立叶变换红外光谱（ftir），拉曼光谱和x射线光电子能谱（xps）表征了所得cqds / ppy复合电极的形貌和组成。此外，以cqds / ppy复合材料为电极，用聚乙烯醇/ licl凝胶电解质隔开，制备了新型柔性asss器件。

为此本文研究将0D 碳量子点 （CQDs）与2D MXene 结合，作为混合光热材料，增强光吸收和光热转化能力，同时使用羧甲基纤维素钠(CMC)/聚丙烯酰胺（PAM） 水凝胶 作为水输运的底物材料，降低水蒸发焓。
