“…PEG-coated SPIONs showed 2θ peaks at 31.35°, 35.35°, 45.1°, 57.15°, 63.07° and 74.5°. The peaks are consistent with peaks of magnetite in the literature matching with the Joint Committee on Powder Diffraction Standards (JCPDS) 19-0629 [33]. Unloaded PCNDs showed a characteristic broad peak between 15° and 35° of PGS polymer center at 23.5° similar to peaks reported for the PGS elastomer in the literature [22,34] (Table 2).…”

Recently, dual-mode imaging systems merging magnetic resonance imaging (MRI) and ultrasound (US) have been developed. Designing a dual-mode contrast agent is complex due to different mechanisms of enhancement. Herein, we describe novel phase change nanodroplets (PCNDs) with perfluoropentane encapsulated in a pre-polyglycerol sebacate (pre-PGS) shell loaded with polyethylene glycol (PEG)-coated iron oxide nanoparticles as having a dual-mode contrast agent effect. Iron oxide nanoparticles were prepared via the chemical co-precipitation method and PCNDs were prepared via the solvent displacement technique. PCNDs showed excellent enhancement in the in vitro US much more than Sonovue® microbubbles. Furthermore, they caused a susceptibility effect resulting in a reduction of signal intensity on MRI. An increase in the concentration of nanoparticles caused an increase in the MR contrast effect but a reduction in US intensity. The concentration of nanoparticles in a shell of PCNDs was optimized to obtain a dual-mode contrast effect. Biocompatibility, hemocompatibility, and immunogenicity assays showed that PCNDs were safe and non-immunogenic. Another finding was the dual-mode potential of unloaded PCNDs as T1 MR and US contrast agents. Results suggest the excellent potential of these PCNDs for use as dual-mode contrast agents for both MRI and US.

It is well known that a layered structure can improve charge transfer and is a favorable catalyst material. Most of them are metal oxides, and some metal hydroxides and carbonates have also been proved to have good catalytic performance. Generally, the preparation method is to prepare the precursor and then calcinate them to get metal oxides. Through literature review and repeated experiments, it is found that cationic membrane electrosynthesis with CeCl3·7H2O as a raw material may be able to prepare metal oxides in one step. Furthermore, whether Fe, which is also a variable metal, can also form metal oxides in one step is investigated. Therefore, in this study, CeO2, Fe3O4, and Fe2O3 nanomaterials with the hierarchical structure are prepared by cationic membrane electrolytic synthesis at room temperature. The composition and microstructure of the nanomaterials are studied using XRD, FTIR, XPS, and SEM. Finally, the electrochemical hydrogen evolution performance of the samples is simply tested.
