Feature film : Mesoporous alumina thin films synthesized with a polymeric template have more than 50% porosity, a narrow pore‐size distribution, high accessibility, and high thermal stability up to 900°C. The inorganic network is composed of sintered nanocrystalline γ‐Al 2 O 3 particles, and the pores are ellipsoidal with a face‐centered cubic mesostructure (see image).
