ABSTRACT

En las últimas décadas los avances en la investigación enfermera han supuesto un incremento del consumo, la generación y producción científica, pero todavía son necesarios cambios importantes para una "cultura de la investigación enfermera". El objetivo general es realizar un análisis de la literatura sobre la investigación enfermera desde los conocimientos y motivaciones, barreras y limitaciones y perspectivas de futuro hacia la investigación. Se puede concluir con los datos recientes que existen déficits sobre los conocimientos y motivaciones de los/as enfermeros/as hacia la investigación y que las barreras y limitaciones en la investigación de los cuidados requieren de estrategias y propuestas de cambio para el futuro de la ciencia enfermera.

ABSTRACT

Nanotechnology allows the synthesis of nanoscale catalysts, which offer an efficient alternative for fuel cell applications. In this laboratory experiment, the student selects a cost-effective anode for fuel cells by comparing three different working electrodes. These are commercially available palladium (Pd) and glassy carbon (GC) electrodes, and a carbon paste (CP) electrode that is prepared by the students in the laboratory. The GC and CP were modified with palladium nanoparticles (PdNP) suspensions. The electrodes efficiencies were studied for ethanol oxidation in alkaline solution using cyclic voltammetry techniques. The ethanol oxidation currents obtained were used to determine the current density using the geometric and surface area of each electrode. Finally, students were able to choose the best electrode and relate catalytic activity to surface area for ethanol oxidation in alkaline solution by completing a critical analysis of the cyclic voltammetry results. With this activity, fundamental electrochemical concepts were reinforced.
