DOI: 10.1007/s11665-018-3793-9
Abstract: The coarse columnar grain layer generated on top of electroforming deposits leads to low surface strength and poor global performance of deposits. Here, we introduce a particle abrasive-induced surface self-nanocrystallization process, which is a part… read more here.

DOI: 10.1080/22797254.2017.1328646
Abstract: ABSTRACT This work seeks to implement surface indicators of porphyry copper deposits (PCDs) at known source regions and to apply these indicators to recognize high- and low-potential mineralization through remote sensing in other areas. Thirty… read more here.
