New CZM for Interfacial Crack Growth [PDF]
Mathematical Problems in Engineering, 2017 The cohesive zone model (CZM) has been widely used for numerical simulations of interface crack growth. However, geometrical and material discontinuities decrease the accuracy and efficiency of the CZM when based on the conventional finite element method (CFEM).

Modulation of Oxygen Vacancies on Cu/ZnO by Promoter for Higher Alcohol Synthesis From Syngas. [PDF]
ChemistryOpenOxygen vacancy (Ov) formation is modulated by promoter incorporation. Additional metal atoms are inserted into ZnO tetrahedral sites in CZA and CZG, thereby promoting vacancy growth. In contrast, a CuCr2 bimetallic phase is produced in CZC, suppressing ZnO defects. Enhanced Ovs promote ethanol formation.
