Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Looking into the Prechamber of a Lean-Burn Gas Engine.

open access: yesJSME International Journal Series B, 1997
Quartz prechamber models have been installed in a constant volume test rig (CVR) for the investigation of prechamber mixing processes. Planar laser induced fluorescence of acetone has been used for a 2-dimensional visualization of flow structure and quantitative analysis of mixture formation.
