HfO2 is a prospective high-k replacement for SiO2 for future integrated circuits. We study energetic of amorphous and nanocrystalline hafnium oxide by high temperature oxide melt solution calorimetry to establish critical sizes where phase stability switches by surface energy terms.
The heating of soil during fires may result in organic matter loss. The ratio of combustion enthalpy of soil organic matter to the alpha-beta quartz transition enthalpy can be used to compare heated and unheated soil. This eliminates the need to weigh samples and is insensitive to differences in water content between heated and unheated soils, making possible in-situ applications in field sites.READ MORE
