Brain micro-vasculature imaging: An unsupervised deep learning algorithm for segmenting mouse brain volume probed by high-resolution phase-contrast X-ray tomography

Alessandra Patera, Anne Bonnin, Marco Stampanoni

High-throughput synchrotron-based tomographic microscopy at third generation light sources allows to probe cm-sized samples at micrometer-resolution. In this work, we present an approach to image a full mouse brain. With Indian-ink as a contrast agent, it ...

Sub-trabecular strain evolution in human trabecular bone

Goran Lovric, Alessandra Patera

To comprehend the most detrimental characteristics behind bone fractures, it is key to understand the material and tissue level strain limits and their relation to failure sites. The aim of this study was to investigate the three-dimensional strain distrib ...

Is desiccation tolerance and avoidance reflected in xylem and phloem anatomy of two coexisting arid-zone coniferous trees?

Alessandra Patera

Plants close their stomata during drought to avoid excessive water loss, but species differ in respect to the drought severity at which stomata close. The stomatal closure point is related to xylem anatomy and vulnerability to embolism, but it also has imp ...

Form - function relationships in dragonfly mandibles under an evolutionary perspective

Alessandra Patera

Functional requirements may constrain phenotypic diversification or foster it. For insect mouthparts, the quantification of the relationship between shape and function in an evolutionary framework remained largely unexplored. Here, the question of a functi ...

Microstructural degradation of silicon electrodes during lithiation observed via operando X-ray tomographic imaging

Alessandra Patera

Due to their high theoretical capacity compared to that of state-of-the-art graphite-based electrodes, silicon electrodes have gained much research focus for use in the development of next generation lithium-ion batteries. However, a major drawback of sili ...

Imaging samples larger than the field of view: the SLS experience

Goran Lovric, Alessandra Patera, Marco Stampanoni

Volumetric datasets with micrometer spatial and sub-second temporal resolutions are nowadays routinely acquired using synchrotron X-ray tomographic microscopy (SRXTM). Although SRXTM technology allows the examination of multiple samples with short scan tim ...

Virtual reading of a large ancient handwritten science book

Giorgio Margaritondo, Frédéric Kaplan, Alessandra Patera, Fauzia Albertin, Marco Stampanoni

We present a fundamental development step of a new technique to read and digitize ancient handwritten documents. Chemical analysis by x-ray fluorescence and x-ray tomography enabled us to decipher words and drawings from inside a closed, 200-pages 18 th ce ...
