Synchrotron light: A success story over six decades

Giorgio Margaritondo

Synchrotron radiation research continues to be a major factor in the progress of science and technology, as it has been for more than half a century. We present different aspects of its history, starting with an unconventional approach: a fictional version ...

From closed testaments to books: Virtual X-ray Reading as an alternate digitization technology for fragile documents

Giorgio Margaritondo, Demetri Psaltis, Fauzia Albertin

In recent years, research and technology made considerable progress in increasing the speed and the safety of the entire digitization process of ancient collections. Despite this, imaging ancient, fragile or un-opened documents remains a formidable challen ...

Q&A: Why use synchrotron x-ray tomography for multi-scale connectome mapping?

Giorgio Margaritondo

To understand how information flows and is used in the human brain, we must map neural structures at all levels, providing visualizations similar to those of Google Earth for continents, countries, cities, and streets. Unfortunately, the imaging and proces ...

The relativistic foundations of synchrotron radiation

Giorgio Margaritondo

Special relativity (SR) determines the properties of synchrotron radiation, but the corresponding mechanisms are frequently misunderstood. Time dilation is often invoked among the causes, whereas its role would violate the principles of SR. Here it is show ...

Ancient administrative handwritten documents: virtual x-ray reading

Giorgio Margaritondo, Frédéric Kaplan, Fauzia Albertin

A method for detecting ink writings in a specimen comprising stacked pages, allowing a page-by-page reading without turning pages The method compris- es steps of taking a set of projection x-ray images for different positions of the specimen with respect t ...

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 ...

Ancient administrative handwritten documents: X-ray analysis and imaging

Giorgio Margaritondo, Frédéric Kaplan, Fauzia Albertin

Handwritten characters in administrative antique documents from three centuries have been detected using different synchrotron X-ray imaging techniques. Heavy elements in ancient inks, present even for everyday administrative manuscripts as shown by X-ray ...

Gold nanoparticles as multimodality imaging agents for brain gliomas

Giorgio Margaritondo

Background: Nanoparticles can be used for targeted drug delivery, in particular for brain cancer therapy. However, this requires a detailed analysis of nanoparticles from the associated microvasculature to the tumor, not easy because of the required high s ...

X-ray-induced Cu deposition and patterning on insulators at room temperature

Giorgio Margaritondo, Ying Chen

X-ray irradiation is shown to trigger the deposition of Cu from solution, at room temperature, on a wide variety of insulating substrates: glass, passivated Si, TiN/Ti/SiO2/Si and photoresists like PMMA and SU-8. The process is suitable for patterning and ...
