The paper "High aspect ratio grating microfabrication by Pt assisted chemical etching and Au electroplating” by Dr. Lucia Romano & coauthors has been highlighted in the "Women in Engineering Materials" Virtual Issue published on Advanced Engineering Materials. This Virtual Issue draws attention to outstanding works within Materials Science created under the lead of women as principal investigators.
Congratulations to Lucia and the x-ray optics design and fabrication team!
With the Virtual Issue "Women in Engineering Materials", the editorial team of Advanced Engineering Materials would like to demonstrate the high impact women have within the research published in this journal and that gender does not matter when it comes to great research output.
“The main challenge in grating-based X-ray interferometry – Lucia said – is the fabrication of high aspect ratio gratings (periodic microstructures). In this paper, we demonstrated a new fabrication approach based on the use of platinum with a double function, as metal catalyst for MacEtch of silicon substrates and as seed layer for gold electroplating. It has been a long and challenging project but the final results are very promising, the route to a new microfabrication technology is definitely opened”.
