Hypersonic phonon propagation in one-dimensional surface phononic crystal / Graczykowski, Bartlomiej (Institut Català de Nanociència i Nanotecnologia) ; Sledzinska, Marianna (Institut Català de Nanociència i Nanotecnologia) ; Kehagias, Nikolaos (Institut Català de Nanociència i Nanotecnologia) ; Alzina, Francesc (Institut Català de Nanociència i Nanotecnologia) ; Reparaz, Juan Sebastián (Institut Català de Nanociència i Nanotecnologia) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia)
Hypersonic, thermally activated surface acoustic waves propagating in the surface of crystalline silicon patterned with periodic stripes were studied by Brillouin light scattering. Two characteristic directions (normal and parallel to the stripes) of surface acoustic waves propagation were examined exhibiting a distinctive propagation behavior. [...]

(Institut Català de Nanociència i Nanotecnologia)
Hydrogel materials offer many advantages for chemical and biological sensoring due to their response to a small change in their environment with a related change in volume. Several designs have been outlined in the literature in the specific field of hydrogel-based optical sensors, reporting a large number of steps for their fabrication. [...]

7 p, 1.5 MB In-line metrology for roll-to-roll UV assisted nanoimprint lithography using diffractometry / Kreuzer, Martin (Institut Català de Nanociència i Nanotecnologia) ; Whitworth, Guy L. (Institut Català de Nanociència i Nanotecnologia) ; Francone, Achille (Institut Català de Nanociència i Nanotecnologia) ; Gomis Bresco, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Kehagias, Nikolaos (Institut Català de Nanociència i Nanotecnologia) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia)
We describe and discuss the optical design of a diffractometer to carry out in-line quality control during roll-to-roll nanoimprinting. The tool measures diffractograms in reflection geometry, through an aspheric lens to gain fast, non-invasive information of any changes to the critical dimensions of target grating structures. [...]

The idea of developing magnetic molecular materials into real functional electronic devices with low-cost and scalable techniques appeared with the emergence of the field several years ago. Today, even though great advances have been done with this aim, the promise of a functional device working at the micro-/nanoscale and at room temperature has unfortunately not completely materialized yet, as their use still strongly depends on the fabrication methodology of a robust device that can be handled and integrated without compromising their functionality.

Diferentes funcionalidades pueden ser obtenidas en diversas superficies a través de topografía en lugar de química, inspirándose en la naturaleza. El principal objetivo de esta tesis es la investigación de la litografía de nanoimpresión (NIL) como una técnica de fabricación factible para modificar superficies y así alterar sus propiedades físicas, utilizándolas para aplicaciones superhidrofóbicas y oleofóbicas. [...]
Different surface functionalities can be achieved by means of topography instead of chemistry, based on inspirations from nature. The main objective of this thesis is the investigation of Nanoimprint Lithography (NIL) as a feasible fabrication technique to modify both organic and inorganic surfaces to alter their physical properties and utilize them for superhydrophobic and oleophobic applications.
