Abstract (english): 
Researchers show that mechanical metamaterials based on ceramic inverse opaline structures with densities in the range of 330-910 kgm-3 are suitable as photonic crystals and have better stiffness- and compressive strength-to-weight ratios as compared to microfabricated optimized strut-based structures. The stiffness- and compressive strength-to-weight ratios are also lower than carbon nanoframes fabricated by interference lithography. Pure silica inverse opal structures and silica inverse opals whose pores have been internally coated by a thin TiO2 layer have been fabricated and their structural and mechanical behavior has been investigated.
