Ongoing research grant (most recent)
Resistive gas sensors based on metal oxides in the form of thin or thick films are the devices most used and studied for the control of toxic and flammable gases in technological processes and open environment. Although a significant amount of work is being devoted to this field of research, efforts are being made in order to find materials that exhibit best surface and bulk properties ...

The process of addition of dopants has been widely used in the processing of new materials. The incorporation of atoms or ions of certain elements in a host matrix has led to obtain new materials with new properties and applications. In nanocrystalline materials, the process of doping has been considered of fundamental importance to stabilize certain crystalline phases and modify the ma...

This research project proposes to develop a new dimension in the relationship between the morphology and physical properties and possible applications related to the different morphologies of nanostructured CuAlO2 phase. We expect through this study clearly describe the process of formation of different morphologies of nanostructured CuAlO2 phase and thus provide the basic knowledge on ...
The zinc oxide (ZnO)compound was the first material in the form of thin films being applied as gas sensor. Although a significant amount of work about the use of ZnO as a gas sensor has been published in recent years, the sensitivity and selectivity increasing with respect to detection of certain types of gases and their use at a temperature closer to ambient remain goals to be achieved...

The process of doping has been widely used for the modification of physical and chemical properties of different materials and may lead to obtain new materials having new properties and applications. In nanocrystalline materials, the doping process has been also considered essential for stabilizing certain crystalline phases. The hydrothermal synthesis method has allowed the synthesis o...
Perovskite materials include a wide group of compounds whose structure in its simplest form can be represented by chemical formula ABO3. One major advantage that the perovskite structure shows is the high degree of flexibility in accommodating a wide variety of atoms in A and B sites, allowing greater control of chemical and physical properties of the material and maintaining its basic ...
