Gas sensors have been increasingly essential in the areas of health and safety. Resistive gas sensors based on nanostructured metal semiconductor oxides (MOXs) stand out due to their high sensitivity and stability. Their main disadvantage lies in their selectivity, sensitivity to moisture, and relatively high operating temperatures. The formation of nanoheterostructures has allowed to obt…
Gas sensor devices display a variety of applications, ranging from environmental monitoring to healthcare. The main attractive of these devices, in the healthcare, is the possibility of performing noninvasive diagnosis of some diseases. Diabetes is a lifelong condition that may cause death and seriously affects the quality of life of a rapidly growing number of peoples. Acetone is a selec…
In past decades, semiconducting metal oxides (MOXs) have been extensively investigated, attracting great attention due to their interesting applications in electronic devices, heterogeneous catalysis, gas sensors, and energy generation. Among the MOXs exhibiting potential properties as sensing layer, n-type semiconductors, more specifically ZnO and SnO2, stand out. Although a significant …
Resistive gas sensors are increasingly being used in our daily lives. Semiconducting metal oxides (MOXs) are an important class of multifunctional materials in the field of materials physics. Among these MOXs applied as resistive sensors for toxic gases, the WO3 and SnO2 compounds have exhibited potential performance. Although promising, the relatively high operating temperatures (>150oC)…
Great efforts have been directed to the development of portable and easy-to-operate gas sensing devices that allow the efficient monitoring of small concentrations of toxic species in a quantitative and selective way. Resistive gas sensors based on semiconducting metal oxides (SMOx) stand out due to their good sensitivity and fair stability. Despite being promising, the operating temperat…
Nowadays, the high agricultural productivity is related to use of the fertilizers, mainly the fertilizer nitrogen which are essentials for large crops, such as corn and rice. The main challenge in this area consists to improve the harnessing of the fertilizers, due the large losses of the nitrogen through volatilization process. This process consists in the oxidation of these sources on t…
The development of efficient sensor devices could make air pollution monitoring more accessible and may be vital in accelerating much-needed reductions in air pollution. Gas sensors based on metal oxides (MOXs) have drawn attention due to their performance in detecting various analytes, especially harmful species. The traditional gas sensors are based on SnO2, In2O3, and WO3, which have c…
Gas detection is important for controlling industrial, and vehicle emissions, agricultural residues, and environmental control. In last decades, several semiconducting oxides have been used to detect dangerous or toxic gases. The excellent gas sensing performance of these gas sensor devices have observed at high temperatures (~250oC), which forbids the use for the detection of flammable a…
