DOI:
https://doi.org/10.3365/KJMM.2024.62.2.142
Abstract
In the modern era, advanced industrial and process technologies in various fields are known to produce harmful gases. These gases typically leak at low concentrations, but continuous exposure can cause serious harm to health and safety. Since human sensory organs cannot detect these risks or leaking hazardous gases, there has.....

https://doi.org/10.3365/KJMM.2023.61.6.414
Abstract
Dihydrogen sulfide (H
2
S) gas has a flammable nature and is one of the most toxic and dangerous gases. Even small concentrations can be fatal to humans. Herein, we investigated the H
2
S gas-sensing features of commercial pristine cerium oxide (CeO
2
) and gadolinium (Gd)-doped CeO
2
(GDC) nanoparticles. First, the sensing materials.....

https://doi.org/10.3365/KJMM.2019.57.11.732
Abstract
To attain high life standards, it is important to develop high-performance non-toxic gas sensors for public safety, environmental pollutant control, industrial processes, etc. Because reports on single element semiconductor-coated semiconducting metal oxides for sensing applications are rare, we synthesized SnO

nanowires and coated them with a 5 nm-thick or 10.....

DOI:
https://doi.org/10.3365/KJMM.2017.55.7.492
Abstract
Pt-functionalized RGO samples were prepared and subsequently irradiated with 2-MeV electron beams (e-beams). The effect of e-beam dose on the structural, electrical, and gas sensing properties of the samples was investigated. E-beam irradiation was found to induce significant microstructural changes in the Pt-functionalized RGO. Measurements of NO
