A review on prognostics and health monitoring of proton exchange membrane fuel cell
Fuel cell technology can be traced back to 1839 when British scientist Sir William Grove discovered that it was possible to generate electricity by the reaction between hydrogen and oxygen gases. However, fuel cell still ...
Surface Morphology Evolution Mechanisms of InGaN/GaN Multiple Quantum Wells with Mixture N2/H2-Grown GaN Barrier
Surface morphology evolution mechanisms of InGaN/GaN multiple quantum wells (MQWs) during GaN barrier growth with different hydrogen (H2) percentages have been systematically studied. Ga surface-diffusion rate, stress ...
An analytical model for the identification of the threshold of stress intensity factor range for crack growth
The value of the stress intensity factor (SIF) range threshold (∆K_th ) for fatigue crack growth (FCG) depends highly on its experimental identification. The identification and application of ∆K_(th )are not well established ...
