In the present work, we used self-assembled colloidal monolayers as lithographic structures for the conformation of ordered Si submicrometer pillars by reactive ion etching. We explored different discharge conditions to optimize the Si pillar geometry. Selected structures were further decorated with gold by conventional sputtering, prior to colloidal monolayer lift-off. The resulting structures consist of a gold crown, that is, a cylindrical coating on the edge of the Si pillar and a cavity on top. We analysed the Au structures in terms of electronic properties by using X-ray absorption spectroscopy (XAS) prior to and after post-processing with thermal annealing at 300 °C and/or interaction with a gold etchant solution (KI). The angular dependent analysis of the plasmonic properties was studied with Fourier transformed UV-vis measurements. Certain conditions were selected to perform a surface enhanced Raman spectroscopy (SERS) evaluation of these platforms with two model dyes, prior to confirming the potential interest for a well-resolved analysis of filtered blood plasma.The Gaelic Athletic Association (GAA) is a major stakeholder in promoting smoke-free policies in Ireland. Several GAA clubs have adopted smoke-free policies, and there is a growing interest among other GAA clubs to also become smoke-free. As such, the purpose of this study is to explore the process of how GAA clubs adopt, implement, and enforce smoke-free policies in order to discover best practices that other clubs could replicate. Representatives from 15 smoke-free clubs were interviewed regarding how their club became smoke-free. Interview data were analyzed, in which four major themes emerged (1) process (planning a smoke-free policy, communicating the policy to the community, providing smoking cessation resources),
