The structure of epitaxial V2O3 films and their surfaces : a medium energy ion scattering study [PDF]

, 2012
Medium energy ion scattering, using 100 keV H+ incident ions, has been used to investigate the growth of epitaxial films, up to thicknesses of ~200 Å, of V2O3 on both Pd(111) and Au(111). Scattered-ion energy spectra provide a measure of the average film

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.
