Journal ArticleDOI
Room temperature alcohol sensing by oxygen vacancy controlled TiO2 nanotube array
TL;DR: In this paper, an electrochemical anodization in the mixed electrolyte comprising NH4F and ethylene glycol with selective H2O content was used to synthesize TiO2 nanotubes, having diameters of 50-70nm and lengths of 200-250nm.
Journal ArticleDOI
Stoichiometry, Length, and Wall Thickness Optimization of TiO2 Nanotube Array for Efficient Alcohol Sensing.
TL;DR: Judicious variation of H2O content in the mixed electrolyte comprising ethylene glycol and NH4F resulted into the desired variation of stoichiometry and the underlying sensing mechanism was correlated with the experimental findings on the basis of structural parameters of the nanotubes.
Journal ArticleDOI
Low temperature acetone detection by p-type nano-titania thin film: Equivalent circuit model and sensing mechanism
TL;DR: In this paper, a nanocrystalline anatase p-type TiO2 thin film was deposited by sol-gel method on thermally oxidized p-Si (2-5-Ω) substrates.
Journal ArticleDOI
New Approach in Designing Resonance Cavity High-Gain Antenna Using Nontransparent Conducting Sheet as the Superstrate
TL;DR: In this article, a resonance cavity antenna (RCA) employing nontransparent solid metal sheet as superstrate is proposed for the first time, and the proposed configuration is much advantageous in terms of design, simplicity, structural stability, fabrication, and cost without compromising in gain, efficiency, and bandwidth.
Journal ArticleDOI
Highly Repeatable Low-ppm Ethanol Sensing Characteristics of p-TiO 2 -Based Resistive Devices
TL;DR: In this paper, a highly sensitive, relatively low-temperature ethanol sensor based on sol-gel derived anatase TiOpotion 2 (ATI 2 ) thin film was presented.
