ABSTRACT
The objective of the research was to design a model that potentiates information management skills supported by the use of technological tools in vocational middle school students of public institutions in the municipality of Ponedera Atlántico. The research was developed under the positivist paradigm, with the hypothetical deductive method and with a projective type of research. The population consisted of 358 vocational middle school students from the city of Ponedera Atlantico. The data collection technique used was a survey whose instrument was a questionnaire, which was subjected to expert validity and structural validity. The analysis of the information was carried out by means of statistical analysis, with the purpose of verifying the hypothesis proposed.

ABSTRACT
This study investigates the efficiency of Bi2O3-ZnO nanocomposites in the photodegradation of two endocrine disruptors: polybrominated diphenyl ether (PBDE) and benzophenone (BP). Bi2O3 particles coated on ZnO (ZNRs) were synthesized through the integration of a hydrothermal technique with a chemical precipitation method. The synthesized nanocomposites were extensively characterized using X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and UV–Vis absorption studies........

ABSTRACT
In order to remove the Al+3 and Cu+2 metals from an chemical industry wastewaters adsorption technology was used with a nanocomposite namely graphene oxide (GO)/ zinc oxide (ZnO) nanocomposite produced under laboratory conditions. The functionalization of GO with zinc oxide nanoparticles (ZnO) improved the adsorption capacity of aluminum (Al+3) and copper (Cu+2). FT-IR spectra of GO, ZnO and GO/ZnO exhibited maximum absorption bands at 3401 1/cm 1842 1/cm and 1197 1/ cm corresponding to the stretching OH-groups and C=O bonds. The GO doped with ZnO nanoparticles exhibited good performances compared to both separete ones...........
