Femtosecond laser micromachining with extended depth of focus by using diffractive lenses
Torres Peiró, Salvador; González Ausejo, Jennifer; Mendoza-Yero, Omel; Mínguez-Vega, Gladys; Lancis, Jesús Elsevier (2014-06-01)We show that a simple diffraction focusing element can alleviate mechanical tolerances in ultrafast laser microprocessing. In particular, we experimentally demonstrate that, in comparison with a conventional refractive ... -
Modification of Nafion Membranes with Polyaniline to Reduce Methanol Permeability
González Ausejo, Jennifer; Cabedo, Luis; Gamez-Perez, Jose; Mollá, S.; Giménez Torres, Enrique; Compañ, Vicente Electrochemical Society (2015)The modification of Nafion membranes with polyaniline (PAni) has been studied as an alternative for reducing methanol crossover in direct methanol fuel cells (DMFC). The modification has been performed by directly polymerizing ... -
