Improved Traffic Flow Efficiency during Yellow Interval at Signalized Intersections Using a Smart Countdown System by Hussain, Qinaat

“…Results from a binary logistic regression model showed that the probability of crossing during the change interval significantly increased for the G-LED condition compared to the control condition, while it decreased in the F-green condition. Furthermore, the experiment disclosed that the odds of crossing the intersection (without red-light running) for the proposed smart advanced warning system (G-LED) were 29.67 and 2.58 compared to the F-green and the control conditions, respectively. …”

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. …”
