Article Comparative Study of ZnO Thin Films Doped with Transition Metals (Cu and Co) for Methylene Blue Photodegradation under Visible Irradiation
Vallejo, William (BarranquillaSede Norte, 2020-05-11)We synthesized and characterized both Co-doped ZnO (ZnO:Co) and Cu-doped ZnO (ZnO:Cu) thin films. The catalysts’ synthesis was carried out by the sol–gel method while the doctor blade technique was used for thin film ...

Design, characterization and quantum chemical computations of a novel series of pyrazoles derivatives with potential anti-proinflammatory response
Burboa-Schettino, Pia (BarranquillaQuímicaSede Norte, 2020-06-24)The synthesis and characterization of the full family of 11 pyrazoles were performed by means of UV–Vis, FTIR, 1 H NMR, 13C NMR, two-dimensional NMR experiments and DFT simulations. As pyrazoles are known for showing ...

TiO2 thin films sensitization with natural dyes extracted from Bactris guineensis for photocatalytic applications: Experimental and DFT study
Diaz-Uribe, Carlos (BarranquillaQuímicaSede Norte, 2020-03-11)TiO2 thin films, sensitized by an anthocyanins-rich extract of a common species found in the Colombian Caribbean region (Bactris guineensis fruits), were used for the photocatalytic degradation of methylene blue. The ...
