Chemical covalent attachment of molecules over conductive electrodes and the control of the properties of the nanoscale junction is the state-of-art for molecular electronics and molecular electrochemistry. In the present proposal we suggest to measure the time-dependent electronic features as accessed by impedance methods for fundamental studies and applications of different types of nan…
A detailed study of the gas sensor response of sensor devices based on 1D nanostructures is proposed in this project. For this, different stoichiometries of tin oxide (SnO2, SnO and Sn3O4) nanobelts, synthesized by the carbothermal reduction method, will be used as sensor elements. The materials will be characterized by X-ray diffraction (XRD), high-resolution transmission (TEM) and scann…
The research topic of this project - the design, fabrication and characterization of nanostructured thin films fabricated with methods of "soft chemistry" - for flexible and/or printable electronics, mobile, using low power operation - is booming, which should produce patents and scientific publications of high impact, helping to increase the competitiveness of research and visibility of …
The detailed study regarding the formation of nanocomposites with high photoelectrochemical activity for hydrogen (H2) evolution as well as the reduction of carbon dioxide (CO2) in high added value compounds (CO, CH4, CH3OH, HCOOH, ethanol) is proposed. Since environmental and energy problems are among the most challenging issues facing the humanity nowadays, the development of efficient …
Conventional water and wastewater treatments, and even sophisticated systems such as reverse osmosis utilized to produce water for hemodialysis are not able to prevent the contamination by organic compounds. This poses serious risks for the environment and/or human health, therefore it is necessary to develop supplementary techniques for water purification. Photocatalysis and photoelectro…
In this research project, a detailed study of the gas sensor performance of field-effect transistor (FET) devices based on 1D semiconducting nanostructures is proposed. For this, different stoichiometries of tin oxide (SnO2, SnO and Sn3O4) and copper oxide (CuO and Cu2O) nanostructures will be used as channel/sensor elements in order to understand the influence of electrical signal modula…
In this research project we propose to conduct a study in order to understand the mechanisms of transport and solid-gas interactions that occur on the surface of SnO, Sn3O4 and SnO2 nanostructures, prepared in different devices. In order to obtain a better understanding of the phenomena involved, we chose to study individually and collectively (single and multiples), the nanobelts of each…

The detailed study on the photo(electro)catalytic activity for hydrogen evolution (H2), the reduction of carbon dioxide (CO2) into high added value compounds (CO, CH4, CH3OH, HCOOH, ethanol), as well as the electrochemical advanced oxidation processes (EAOPs) to remove organic pollutants from wastewaters are proposed in this research. The effectiveness of these methodologies is based on t…
In this research project, a comprehensive phenomenological investigation of the conduction mechanisms associated with the gas sensing performance of field-effect transistors (FET) based on one-dimensional (1D) semiconducting metal oxide (SMOx) nanostructures is proposed. For this, FET devices with the channel/sensing element composed of single or multiple tin oxide (SnO2, SnO and Sn3O4) a…
The main motivation for this project is to explore the gas sensor response and transport mechanism of tin oxide-based nanostructures through the solid-gas interactions study on individuals SnO, Sn3O4 and SnO¬2 nanobelts, with different diameters, against oxidizing and reducing gases. SnO2-based sensors are already well established in the literature, but thermodynamically less stable oxide…
