1. Development and production of heterostructured thin films with unique properties for highly effective detection of hazardous gases AP22785922
This project focuses on developing advanced gas sensors based on zinc oxide (ZnO) and its heterostructures to detect hazardous gases such as NOx, COx, NH3, H2S, and SOx. ZnO layers will be synthesized using methods like electrospinning, hydrothermal synthesis, and SILAR. At the same time, substrates such as silicon and ITO will be utilized, along with gold-interdigitated electrodes (IDE) fabricated via magnetron deposition. The research aims to optimize the structural, electrical, and optical properties of ZnO and ZnO/MOS (metal oxide semiconductor) composites, improving their sensitivity, selectivity, and stability. Comprehensive characterization will analyze crystal structure, band gap, thickness, and conductivity. Gas sensitivity studies will evaluate operating temperatures and response times for detecting toxic compounds. Additionally, heterostructured ZnO/MOS composites with enhanced sensor properties will be developed to achieve high-performance detection. The project will culminate in the design and testing of an Arduino-based sensor platform for real-time gas monitoring, demonstrating its practical application in environmental safety. This work aims to create a working prototype of a reliable, selective, and highly sensitive gas sensor for monitoring air quality and detecting harmful gases in diverse industrial and environmental settings.

Development of highly sensitive MOS based nano-film gas sensors 021220CRP0122
Project’s goal is to synthesize novel miniaturized gas sensors based on polycrystalline
MOS and to improve their morphological and electrical properties, as well as to increase the sensitivity and
response time to toxic gases. Also, an appropriate MOS gas sensor is aimed to be integrated within Li-ion
battery pack for early diagnosis of cell failure and thermal runaway.
