Along with high sensitivity in detecting gas, the response and recovery times of semiconductor gas sensors are of considerable importance for real life applications. In most cases, the recovery time is more than the response time. At the same time, water vapor present in the ambient, is chemisorbed on the tin oxide, SnO2 surface and the water molecules dissociate into hydroxyl species, which ac...

the aim of this research is preparation of sno2 nanowires by means of thermal chemical reaction vapor transport deposition (tcrvtd) method from sno powders. the morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (fe-sem), eds, and xrd. the xrd diffraction patterns reveal that the sno2 nanowires have...

Due to their highly reversible capacity, tin-sulfide-basedmaterials have gained attention as potential anodes for sodium-ion and lithium-ion batteries. Nevertheless, the performance of tin sulfide anodes is much lower than that of tin oxide anodes. The aim of the present investigation is to improve the electrochemical performances of SnS anodes for sodium-ion batteries using conventional organi...

This paper is aimed at selectivity investigation of gas sensors, based on chemically modified nanocrystalline tin dioxide in the detection of CO and ammonia mixtures in air. Sol-gel prepared tin dioxide was modified by palladium and ruthenium oxides clusters via an impregnation technique. Sensing behavior to CO, NH3 and their mixtures in air was studied by in situ resistance measurements. Using...

Miniaturized electronic noses to rapidly detect and differentiate trace amount of chemical agents are extremely attractive. Use of tin oxide nanoparticles as sensing elements has been proved to significantly improve both the response time and the sensitivity of gas sensors or electronic noses. In this paper, we report the synthesis of pure tin oxide nanoparticles using a simple, convenient, and...

Lithium-Sulfur (Li-S) batteries as the next-generation battery system have an ultrahigh theoretical energy density. However, limited conversion of polysulfides in sulfur cathodes deteriorates performance Li-S batteries. In this study, we develop a novel titanium nitride (TiN) catalyst for via atomic layer deposition (ALD). The synthesized ALD-TiN shows controllable ultrafine particle size (<2 n...

Abstract The steady state responses of chemical sensors like the tin-oxide and composite conducting polymer sensors exhibit power law dependency on the vapor concentration. In this research, it is shown that linearization of measured (raw) sensor signals by an inverse power scaling improves class separability in feature space, hence the classification efficiency of electronic noses based on the...

Carbon-coated, carbon nanotube (CNT)/tin(oxide) spongy coaxial nanostructures, CNT/Sn(O(2))@C, with large areal mass loadings have been developed by employing a three-dimensional CNT sponge as a backbone. The freestanding spongy coaxial nano-architecture demonstrates exceptional electrochemical characteristics of tin-based anode materials with appropriate structural engineering for energy stora...

The atomic layer deposition sALDd of tin oxide thin films has been examined using in situ quartz crystal microbalance sQCMd and Fourier transform infrared sFTIRd techniques. The SnOx films were deposited using sequential exposures of SnCl4 and H2O2 at temperatures from 150 to 430 °C. The linear growth of the tin oxide ALD films was observed by both the mass gain during QCM measurements and the ...
