Light scattering and absorption properties of dust particles retrieved from satellite measurements [PDF]
, 2008 We use the radiative transfer model and chemistry transport model to improve our retrievals of dust optical properties from satellite measurements. The optical depth and absorbing optical depth of mineral dust can be obtained from our improved retrieval ...

Alkali-Activated Metakaolins: Mineral Chemistry and Quantitative Mineral Composition
Minerals, 2022 The reaction products resulting from the alkali-activation of metakaolin are impacted by the composition of the initial kaolin, and amount of alkali-activated kaolinite and water. The present study focused on analyzing these parameters on the metakaolins calcined at 800 °C from three kaolins, and the metakaolins’ alkali activation for 2, 3 and 28 days.
