“…The mean values of Zeta potential in IPA and DCM exceeded −25, which was much larger than those in MeOH and DMSO with the values of −16.80 ± 0.73 and −7.52 ± 0.51 respectively, and indicated a better stability. The PDI values in four solutions were between 0.6–1.0, where the value in DMSO was the smallest while in IPA was the largest [ [41] , [42] , [43] , [44] ]. In summary, although the dispersibility of the OpiCa1-PEG-PLGA nanomicelles by thin film dispersion method in IPA needed further improvement, it had the smallest particle size and the best stability, making it a candidate nanoparticle for further research.…”

Crystal structure is closely related to the function of materials, and understanding of crystal structure is essential not only in the scientific field but also in the industrial field for applications of materials. We introduce the extended unit cell (EUC) model with two vectors to effectively represent complex nanoparticle structures such as twinning and multiple twinning. This model overcomes the limitations of conventional single-and two-phase analyses in capturing such structures. Furthermore, the local atomic distribution in Ir−Pd bimetallic NPs was investigated in detail, and it was found that Ir and Pd are at sites represented by a single vector while suggesting the localized presence of Ir at sites where the vector changes. Such a detailed observation of local atomic distribution is difficult to represent by conventional two-phase analysis, highlighting the great advantage of our proposed EUC model. This study not only aims to enhance the understanding of nanoparticle structures and their properties for catalysis but also proposes a methodology that significantly reduces computational costs by simplifying the representation of complex structures. It is particularly suitable for catalytic applications requiring precise structural control.
