Hydrogen is attractive as an abundant source for clean and renewable energy. However, due to its highly flammable nature in a range of concentrations, the need for reliable and sensitive sensor/monitoring technologies has become acute. Here a solid-state hydrogen sensor based on solution-processable p-type semiconductor copper thiocyanate (CuSCN) i...

Ozone (O3) is one of the main indoor as well as environmental air pollutant, thus its detection is of great importance. As a result, plenty of materials have been tested as O3 gas sensing elements, over the last fifty years. In this work, the gas sensing performance of Copper (I) Thiocyanate (CuSCN) powder against O3, is presented. The structure of...

Al-doped NiO (NiO:Al) has attracted the interest of researchers due to its excellent optical and electrical properties. In this work, NiO:Al films were deposited on glass substrates by the radio frequencies (rf) sputtering technique at room temperature and they were tested against ozone gas. The Oxygen content in (Ar-O2) plasma was varied from 2% t...

Al-doped Nickel oxide (Al:NiO) nanostructured thin films, prepared by RF sputtering technique, were tested for NO2 gas detection. The films were deposited on alumina substrates with thicknesses ranging between 52 nm and 167 nm, while the at.% of Al was varied from 5.0% to 6.7%. The effect of the thickness on the morphological, structural and optica...
