Damage characterization in waveguides with ultrasonic shear waves [PDF]

, 2015
Damage can be viewed as a continuum discontinuity. In order to identify and quantify damage, the present study investigates the dependence of reflection and transmission coefficients from a discontinuity in a waveguide using a finite element model.

Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

Advanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.
