2024年4月23日 · We report here a general sustainable strategy for the design of highly defective and ultra-small tetravalent MOFs (Zr, Hf) crystals (ca. 35% missing linker, 4–6 nm). Advanced characterizations have...

Porous nanocrystals of metal–organic frameworks (MOFs) offer greater bioavailability, higher surface-to-volume ratios, superior control over MOF membrane fabrication, and enhanced guest-sorption kinetics compared to analogous bulk phases, but reliable synthesis of uniformly sized particles remains an outstanding challenge.

2022年2月18日 · Various characterization techniques such as FTIR, FE-SEM, XRD, TGA, and DLS characterization techniques are used to analyze the chemical composition, surface morphology, crystal structure and crystallinity, thermal stability, and particle size distribution of the MOFs, respectively.

2019年8月23日 · Through the combined use of DLS analysis in solutions and microscopic analysis of the solvent-free products, we found that only two kinds of molecular assemblies formed in the zinc MOF...

2025年3月29日 · The dynamic light scattering (DLS) test was used to investigate the hydrodynamic diameter and particle size distribution of the metal–organic framework (CuBT) and the composite (Fe 3 O 4 @PVP@CuBT) in a liquid (Table 4, Fig. 8). DLS analysis showed that the MOF and composite have average particle diameters of 1025.8 and 870.3 nm, respectively.

电镜看到的是纳米颗粒的更直接的二维化的尺寸，而dls检测的是水动力学半径，水动力学半径的检测因为检测的范围包括了纳米颗粒表层的水分子，一般都会偏大。

2021年8月15日 · An ultrasensitive DLS immunosensor platform was developed through the MOF-assisted burst release of AuNPs in combination with GISG strategy for scattering signal amplification. The as-prepared MOF@AuNP can be readily decomposed in weak alkaline solution to release the numerous small-sized AuNPs and reduce the background light scattering signal.

2020年1月1日 · Metal ions and some organic linkers are arranged in regular way by coordinate linkage to form metal organic frameworks (MOFs) in proper solvent, temperature, and atmospheric condition. MOFs have several unique characteristics which highlighted, over others, organic polymers and inorganic compounds.

2022年8月1日 · Herein, with porous Cu-based metal–organic framework (Cu-MOF) as the precursor, we report a convenient partial in-situ vulcanization strategy to construct CuS@Cu-MOF nanocomposites as multifunction nanoagents for maximizing anti-cancer efficacy.

2024年4月27日 · 研究团队在2D绝缘体上合成了一种2D kagome结构 MOF，并使用扫描隧道显微镜（STM）和光谱学揭示了MOF的电子能隙约为200 meV，与动态平均场理论（DMFT）预测的莫特绝缘体一致。
