Refraction beats attenuation in breast CT
Michał Rawlik, Alexandre Pereira, Simon Spindler +17
For a century, clinical X-ray imaging has visualised only the attenuation properties of tissue, which fundamentally limits the contrast, particularly in soft tissues like the breas…
High aspect ratio arrays of Si nano-pillars using displacement Talbot lithography and gas-MacEtch
Z. Shi, K. Jefimovs, M. Stampanoni +1
Structuring Si in arrays of vertical high aspect ratio pillars, ranging from nanoscale to macroscale feature dimensions, is essential for producing functional interfaces for many a…
High aspect ratio silicon structures by Displacement Talbot lithography and Bosch etching
Konstantins Jefimovs, Lucia Romano, Joan Vila-Comamala +6
Despite the fact that the resolution of conventional contact/proximity lithography can reach feature sizes down to ~0.5-0.6 micrometers, the accurate control of the linewidth and u…
Towards Sub-micrometer High Aspect Ratio X-ray Gratings by Atomic Layer Deposition of Iridium
Joan Vila-Comamala, Lucia Romano, Vitaliy Guzenko +3
X-ray grating interferometry is an excellent technique for X-ray phase contrast imaging and X-ray wavefront sensing with applications in materials science, biology and medical diag…
High aspect ratio metal microcasting by hot embossing for X-ray optics fabrication
Lucia Romano, Joan Vila-Comamala, Matias Kagias +4
Metal microstructured optical elements for grating-based X-ray phase-contrast interferometry were fabricated by using an innovative approach of microcasting: hot embossing technolo…
Effect of Isopropanol on Gold Assisted Chemical Etching of Silicon Microstructures
Lucia Romano, Joan Vila-Comamalab, Konstantins Jefimovs +1
Wet etching is an essential and complex step in semiconductor device processing. Metal-Assisted Chemical Etching (MacEtch) is fundamentally a wet but anisotropic etching method. In…
Anisotropic de Gennes narrowing in confined fluids
Kim Nygard, Johan Buitenhuis, Matias Kagias +3
The collective diffusion of dense fluids in spatial confinement was studied by combining high-energy (21 keV) x-ray photon correlation spectroscopy and small-angle x-ray scattering…
