Our work focuses on unique molybdenum oxide-based porous capsules which allow to study nanoscaled cation separation and dynamics, and model cells with respect to (i) trans-membrane cation transport across the pores and (ii) design and fine-tuning of the cavity, so as to provide hydrophilic or hydrophobic conditions, by attachment of appropriate ligands to the oxidomolybdenum framework. We intend to supplement the work accomplished in the bygone two-and-a-half years by extending and refining the interior equipment of the capsules, and by rarefying, through multinuclear NMR, the methodological aspects of the investigation and the analysis of the dynamics of intracellular incidents, including guest exchange within the cavity and intra/extra-"cellular" exchange of organic building blocks (ligands). Furthermore, it is intended to study new phenomena, e.g. dynamical exchange equilibria within the capsules.

我们的工作集中在独特的氧化钼多孔胶囊上，它允许研究纳米尺度的阳离子分离和动力学，并建立关于(I)跨膜阳离子跨孔传输和(Ii)腔的设计和微调的细胞模型，以便通过将适当的配体连接到氧化钼骨架来提供亲水或疏水条件。我们打算补充过去两年半完成的工作，扩展和改进胶囊的内部设备，并通过多核核磁共振揭示调查的方法学方面和细胞内事件的动力学分析，包括腔内的客体交换和有机构件(配体)的细胞内/细胞外交换。此外，它还打算研究新的现象，例如胶囊内的动态交换平衡。
