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.en1438-165620151014201424Wiley-VCH Verl.PhysikTechnikJournal Article10.1002/adem.201500118Other
