Cracking behavior and mechanism of gibbsite crystallites during calcination
, 2019 Cracking is one of the major contributors to the breakage of gibbsite particles during calcination, which generates superfine particles causing detrimental effects to the quality of product in the downstream smelter grade alumina production.

Data fusion of gamma and x‐ray spectra via Common Dimensions for soil erosion characterization
Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.Abstract This study explores the synergistic application of energy dispersive x‐ray fluorescence (EDXRF) and gamma‐ray spectrometry (GRS) raw spectra to characterize soil redistribution. The evaluation employs Common Dimensions (ComDim), a multiblock non‐supervised machine‐learning technique, to identify shared latent patterns across nuclear and atomic
