Optical coherence tomography measurement of capillary filling in porous silicon

The use of nanoporous structures with known morphology allows studying the properties of fluids in conditions of strong spatial confinement. Alternatively, the capillary filling of nanoporous structures with simple fluids provides information on their morphology. When a liquid enters the porous structure there is an increase in the optical path of the porous layer, and measuring this optical path as a function of position and time allows evaluating the filling dynamics of the pores. In this work, we determined the capillary filling dynamics of nanostructured porous silicon (PS) by optical coherence tomography. The high spatial resolution of this technique allows one not only to follow the position of the liquid front as a function of time but also to resolve in detail the filling fraction profile of the liquid front inside the PS matrix. Moreover, these profiles contain information about the pore size distribution in the PS structure. Therefore, we show how the determination and analysis of the filling fraction profile along the advancing liquid front can be used as a method to study the pore size distribution inside PS structures.Fil: Sallese, Marcelo Daniel.

Digital holographic microscopy implementation for capillary filling measurements in nanoporous materials

We report the implementation of lensless off-axis digital holographic microscopy as a non-destructive optical analyzer for nano-scale structures. The measurement capacity of the system was validated by analyzing the topography of a metallic grid with ≈ 150 nmthick opaque features. In addition, an experimental configuration of self-reference was included to study the dynamics of the capillary filling phenomena in nanostructured porous silicon. The fluid front position as a function of time was extracted fromthe holograms, and the typical square root of time kinematics was recovered. The results shownare in agreement with previous works on capillary imbibition in similar structures and confirm a first step towards unifying holographic methods with fluid dynamics theory to develop a spatially resolved capillary tomography system for nanoporous materials characterization.Fil: Budini, Nicolas.

Development of a simple method based on LIBS for evaluation of neutron production targets made of hydrogen isotopes

In the present work we propose a fast and simple method, based on Laser Induced Breakdown Spectroscopy (LIBS), to evaluate Neutron Production Targets. Targets of interest consist of hydrogen (particularly deuterium or tritium) contained in a titanium matrix. The method aims to evaluate the relative content of hydrogen within the titanium matrix, in order to determine if the target is “accepted” or “rejected” according to this content. Several deuterium targets have been fabricated (TiDx), with different deuterium concentrations, and different techniques have been used to characterize their surfaces. Optical Coherent Tomography has been used to characterize the size and shape of LIBS holes, in order to determine LIBS depth of analysis. Grazing Incidence X-ray Diffraction has been used to determine a range for deuterium relative content. Elastic Recoil Detection Analysis (ERDA) is proposed for future LIBS calibration, since it provides a single value for relative content, has a depth of analysis similar to LIBS and also allows to distinguish between different isotopes. ERDA first results are reported in comparison with LIBS results.Fil: Gaviola, Pedro A.. Comisión Nacional de Energía Atómica; Argentina. Universidad Nacional de San Martín.
