In this experiment, performed at the Nanoscopium beamline at SOLEIL synchrotron, we explored a novel approach to X-ray imaging by using a X-ray diffuser to generate a pseudo-thermal light source with tunable coherence. By conducting the experiment at a synchrotron, we were able to harness a bright X-ray beam to study how partially coherent light interacts with structured objects. This allowed us to take the first steps toward demonstrating lensless imaging techniques that could work with partially incoherent light sources, opening new possibilities for high-resolution imaging in more accessible settings.

We sincerely thank the entire SOLEIL team for their invaluable support and for providing such a welcoming and collaborative atmosphere throughout the experiment!

A distinguished delegation organized by the Austrian Embassy visited the Instituto Superior Técnico (IST) this week with the aim of exploring potential collaborations and partnerships. The visit was led by Austrian Research Centers GmbH (ARC), Austria’s largest research center dedicated to applied research and development outside the university sector. This initiative marks a significant step towards strengthening the research and innovation ties between Austria and Portugal.

The primary goal of the visit was to gain a comprehensive understanding of IST’s organizational structure, including its dynamic educational environment and extensive research activities. This foundational knowledge is crucial for establishing future partnerships. The delegation focused on identifying areas of convergence between IST’s capabilities and the interests of Austrian enterprises, with the aim of fostering collaborative opportunities.

During the visit, the delegation sought to pinpoint synergies between IST’s research strengths and the strategic interests of Austrian businesses. By identifying these common areas, the delegation aims to pave the way for joint research and innovation projects. This initiative is expected to lead to strategic partnerships that leverage the strengths of both Austrian and Portuguese institutions.

A significant aspect of the visit was the initiation of a proactive and constructive dialogue between IST and the Austrian business entities. The discussions aimed to create an environment conducive to developing strategic partnerships and collaborative research initiatives. The dialogue focused on leveraging each institution’s strengths to foster innovation and address common challenges in the industry.

The delegation comprised several high-profile individuals from Austria’s research and industrial sectors:

• Michael Auer: Managing Director of the Austrian Institute for Packaging (OeIV)
• Bernhard Ecker: Journalist from Trend PRESS
• Iris Filzwieser: President of Austrian Cooperative Research (ACR) and CFO of Mettop GmbH
• Wolfgang Haidinger: Department for Research, Technology, and Innovation at the Federation of Austrian Industry (IV)
• Peter Hofer-Hauser: Deputy Managing Director of the Austrian Foundry Institute (OGI)
• Rita Kremsner: Deputy Managing Director of ACR and the visit organizer
• Hartmuth Schröttner: Senior Scientist at the Centre for Electron Microscopy (ZFE)
• Christa Zengerer: Managing Director of the Austrian Foundry Institute (OGI)
• Daniel Zins: Department of Innovation & Digital Transformation at the Austrian Economic Chamber (WKO)

This visit represents a critical step towards fostering closer research and innovation ties between Austria and Portugal. By encouraging collaborations between IST and Austrian entities, both countries can benefit from shared knowledge, resources, and technological advancements. The proactive dialogue and the identification of synergies during the visit are expected to lead to impactful joint initiatives.

As the delegation concluded its visit, the groundwork for future partnerships and collaborative projects was effectively laid. The potential collaborations between IST and Austrian research and industrial entities promise to drive innovation and contribute significantly to the technological and industrial advancement of both nations. The visit not only highlighted the mutual benefits of such collaborations but also underscored the commitment of both countries to advancing research and development through strategic partnerships.

NanoXCan team gathered in Hannover, at the Rathaus, with international experts on IDI to discuss the potential of the technique for the NanoXCan X-ray microscope. The workshop was complemented by a 2 day work meeting of the project team. 

Pablo Claveria from IST today participated in the epp team’s Journal Club by reviewing the F. Frost et al PRL paper “Imaging via Correlation of X-Ray Fluorescence Photons”. It was followed by a live demonstration of varying speckle size at the VOXEL lab.

Mariana Cunha da Silva has been working on Spectral Broadening and post-compression, at the Voxel lab in IST.

During this experiment Mariana mentioned that in order to achieve pulses in the very limit of temporal duration requires not only an ultrashort laser system, such as the ones available in the laboratories of the GoLP team but also a post-compression installation, an extra set of equipment that broadens the spectrum allowing, after, the temporal compression of the pulse. 

Here we see how the pulse spectrum changes while propagating inside a Hollow Core Fiber, a thin cylindrical piece of glass filled with a noble gas, in this case, Argon.
