    • It should be mentioned that Ruben et al.3 reported molecular-level visualization of the structure of particulate silica and organic AGs by high-resolution TEM, which involved painstaking preparation of vertical Pt-C replicas. This state-of-the-art replication technique is, however, very labor intensive and, hence, is not suitable for convenient analysis of AG morphology

    • Low-density AGs are notoriously known for their poor mechanical properties, related to the fact that their elastic modulus decreases highly superlinearly with decreasing monolith density, with an exponent of ∼3-4.9

    • Note that the morphology revealed by LVSEM for cross-sections, prepared by the fracture of AG monoliths, is attributed to the pore structure rather than to an artifact of sample preparation because (i) similar pore structures were revealed for both cross-sections and exterior surfaces of the same AG monolith and (ii) electron microscopy findings correlate well with SAXS data, as discussed in the text
