Optimized n-Butanol Sensing Performance of ZnCeO2 and ZnCuCeO2 Nanocomposites at Room Temperature

Published in ECS Journal of Solid State Science and Technology

ZnCeO2 and ZnCuCeO2 nanocomposites (NCs) were successfully synthesized using a simplistic co-precipitation method. The structural, morphological, and optical properties of the nanocomposites were thoroughly characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy, Raman spectroscopy, scanning electron microscopy, and ultraviole...

Review—MOS-Based Benzene, Toluene, Ethylbenzene, and Xylene Gas Sensors

Published in Journal of The Electrochemical Society

Gas sensing technology has evolved over the last 50 years but there has been a lacuna to understand the sensing mechanism. The understanding becomes even more complicated when gases like Benzene, Toluene, Ethyl Benzene, and Xylene (BTEX) are sensed using conventional gas sensors. BTEX gases have inert chemical behaviour, making it difficult to dete...

First-principles exploration of N- and Pd-doped graphene as CO and NO2 gas sensor for operation status evaluation in AIS...

Published in Physica Scripta

To evaluate the operation status of air insulated switchgears (AIS), this work purposes N- and Pd- embedded graphene (N- and Pd-graphene) as potential gas sensors upon two typical faults gases (CO and NO2) from the first-principles simulations. It is found that the N and Pd atoms can be stably trapped on the C-vacancy of the C-defected graphene wit...

Synthesis and Properties of Eu and Ni Co-Doped ZnS Nanoparticles for the Detection of Ammonia Gas

Published in ECS Journal of Solid State Science and Technology

Zinc sulfide nanoparticles were synthesized successfully via chemical co-precipitation, both in undoped form and co-doped with Europium (Eu) and Nickel (Ni). All prepared samples exhibited cubic zinc blende structure as confirmed by X-ray diffraction (XRD). The average particle size ranged from 3 to 6 nm for both pure and (Eu, Ni) co-doped ZnS, wit...

Room-temperature highly sensitive triethylamine detection by few-layer Nb2CT x MXene nanosheets

Published in Nanotechnology

MXene, a class of two-dimensional materials that are emerging as rising stars in the field of materials, are receiving much attention in sensing. Ti3C2T x MXene, the most maturely researched MXene, is widely used in energy, biomedical, laser, and microwave shielding applications and has also been expanded to gas sensing and wearable electronics app...

Carbon nanowall-based gas sensors for carbon dioxide gas detection

Published in Nanotechnology

Carbon nanowalls (CNWs) have attracted significant attention for gas sensing applications due to their exceptional material properties such as large specific surface area, electric conductivity, nano- and/or micro-porous structure, and high charge carrier mobility. In this work, CNW films were synthesized and used to fabricate gas sensors for carbo...
