Nanostructured ZnO on cotton fabrics – A novel flexible gas sensor & UV filter
Dinesh Kumar Subbiah,Ganesh Kumar Mani,K. Jayanth Babu,Apurba Das,John Bosco Balaguru Rayappan +4 more
TL;DR: In this paper, the surface of carbon cellulosic fabric was modified by solgel and sputter seed layer-coated sol-gel techniques, which showed a maximum UV protection factor (UPF) of 378.
Journal ArticleDOI
Nanostructured Cerium-doped ZnO thin film – A breath sensor
Arockia Jayalatha Kulandaisamy,Vignesh Elavalagan,Prabakaran Shankar,Ganesh Kumar Mani,Ganesh Kumar Mani,K. Jayanth Babu,John Bosco Balaguru Rayappan +6 more
TL;DR: In this article, thin film based chemi-resistive Cerium-doped ZnO sensors were developed for detecting acetone and ethanolamine, which are the notable biomarkers of diabetes mellitus and carcinoma respectively.
Journal ArticleDOI
Growth and characterization of spray pyrolysis deposited copper oxide thin films: Influence of substrate and annealing temperatures
TL;DR: In this paper, the effect of substrate and annealing temperatures on the structural, morphological, optical and electrical properties of spray-deposition copper oxide thin films was investigated and the films were deposited on glass substrates using 0.05 m of cupric acetate precursor at the substrate temperatures of 523, 623 and 723 K.
Journal ArticleDOI

TL;DR: In this article, the effect of gold concentration in Au@TiO2 nanocomposites on their sensing properties was evaluated by XRD, XPS and SEM methods and then tested as gas sensing devices towards a number of volatile compounds.
Journal ArticleDOI
Heptazine based organic framework as a chemiresistive sensor for ammonia detection at room temperature
Nidhi Sharma,Neha Sharma,Parthasarathy Srinivasan,Sunil Kumar,John Bosco Balaguru Rayappan,Kamalakannan Kailasam +5 more
TL;DR: In this article, a heptazine based microporous polymer sensor for the detection of ammonia at room temperature and under ambient conditions was demonstrated for the first time, which demonstrated an enhanced response (166 at 70% RH and 47 at 84% RH) towards 50 ppm of ammonia with response and recovery times of 65 and 9 s.
