The researches performed by the chemical area of the Department of Engineering and Applied Sciences refer to the topics of organic chemistry, inorganic chemistry and structural characterization, photocatalysis and textile chemistry.
In the following, the main present research activities are described.
Synthesis and characterization of simple and functionalized azahelicenes for applications in the fields of sensors, organometallics, DNA intercalation, physico-chemical studies of spectroscopic properties.
We investigate the structure-properties correlation in solid state inorganic materials. In particular, we have a long time expertise with perovskites, one of the most frequent structural class in functional oxides. The physico-chemical properties of perovskites oxides, such as colossal magnetoresistance, ionic conductivity, dielectric properties and superconductivity, are used in a wide variety of applications. Currently, we are investigating the La1-xSrxFe1-yMyO3 system, where M is a transition metal, a promising cathode material for solid oxide fuel cells (SOFCs).
The research activity focuses on the development of new photocatalysts, which use the energy of photons to catalyze a chemical reaction. In particular, we study solid photocatalysts for degradation of organic pollutants mainly in liquid phase. Photocatalytic materials are prepared by means of sol-gel synthesis and characterized by spectroscopic techniques as XRD, FT-IR, DRS, etc. In addition, our interest is to realize lab-scale photoreactors for wastewater treatments.
The goal of the research is to increase the properties of the polymer surfaces. The study is focused on the synthesis, via sol-gel, and characterization of inorganic nanoparticles and hybrid thin films with controlled composition, size and morphology for the treatment of the polymer surfaces. The main results are polymer surfaces with flame retardant9, water/oil repellent, photocatalytic and halochromic properties. In particular, through these surface treatments, technical fabrics and wearable sensors are studied and developed.
