Understanding the False Positive of Modified Martensitic Steels in Sweet & Sour Service Conditions Using a Point Defect Model Perspective by Martinez, Alan

“…Electrochemical tests were performed using a 1L autoclave holding 35 bar of CO2 gas with and without H2S at temperatures varied from 25 °C to 150 °C in salt brine solutions with a pH of 3.5. The point defect model approach is used in conjunction with potentiodynamic polarization and chronoamperometry to observe changes in cation vacancy diffusivity that contribute to strengthening and instability. …”

Tailoring the defects of sub-100 nm multipodal titanium nitride/oxynitride nanotubes for efficient water splitting performance by Eid, Kamel

“…XPS, XPS imaging, Auger electron spectra, and positron annihilation spectroscopy disclosed that the high nitridation rate induced the generation of a mixture of Ti-nitride and oxynitride with various vacancy-type defects, including monovacancies, vacancy clusters, and a few voids inside TiOxNTs. These defects decreased the bandgap energy to 2.4 eV, increased visible-light response, and enhanced the incident photon-to-current collection efficiency (IPCE) and the photocurrent density of TiONxNTs by nearly 8 times compared with TiO2NTs, besides a quick carrier diffusion at the nanotube/electrolyte interface. …”
