Graphical Abstract
  • prepared by solgel synthesis. Dikin et al. and Ni et al. studied SiO2 nanowires (NWs) grown at high temperature with the vapor–liquid–solid method, by using resonance and the three-point bending methods, respectively [13][14]. Houmadi et al. investigated the mechanical properties of SiO2 nanotubes (NTs
  • ), which were prepared by solgel synthesis using organic NT templates, by using three point bending [15]. The differences of the values of the Young’s modulus measured by the listed methods were approximately 40%, which can probably be attributed to peculiarities of the measurement techniques. The effect

  • a ligand loss of the microtemplate [83]. In this way, the nanoparticles are not able to develop into a full-grown zeolite. Instead, they form assemblies by edge-sharing (Figure 7a), similar to the case in solgel synthesis [155], resulting in interparticle mesoporosity. The drawback in this

  • usually the inverse miniemulsion technique has to be applied. Here, water soluble precursor compounds (e.g., Ti- or Si-glycolates, Zr or Ce-salts) for solgel synthesis and, if desired, templating surfactants, such as CTAB, are dissolved in water, acting as the dispersed phase. After miniemulsification
