The Universitat de València hosted the European Focused Ion Beam Network (EU-FIB.net) 2025 Workshop, a four-day international event co-organized by the Institute of Molecular Science (ICMol) and the EU-FIB.net network. The workshop brought together leading experts from Europe and beyond to discuss the latest developments in Focused Ion Beam (FIB) processing and its applications in science and technology.

Held at the Marie Curie Auditorium in the 1 SC building (2nd floor) of the Parc Científic de la Universitat de València in Paterna, the workshop featured a rich program of scientific talks and a lively poster session, providing a platform for exchanging ideas and fostering new interdisciplinary collaborations between academia, industry, and research institutions.

Attendance and programme at a glance: the workshop brought together 107 participants and featured 64 scientific contributions spanning invited, tutorial, industry, oral, and poster sessions.

The opening session featured Rosa Córdoba (ICMol, Universitat de València), local organizer of the event; Gregor Hlawacek (HZDR), EU-FIB.net coordinator; and Pedro Carrasco, director of the Parc Científic de la Universitat de València.

Throughout the four days, renowned invited speakers presented cutting-edge results in key areas such as nanofabrication, materials science, advanced microscopy, and scientific instrumentation development. Among them were:

●      Frédéric Adamski (Safran Tech, France), expert in microstructural characterization of metal alloys.

●      Frances Allen (University of California, Berkeley, USA), researcher specializing in electron and ion beam microscopy for atomic-scale studies.

●      Alex Belianinov (Sandia National Laboratories, USA), pioneer in combining machine learning with advanced microscopy techniques.

●      Daniel Bothner (University of Tübingen, Germany), research group leader in hybrid quantum systems with superconducting microwave circuits.

●      Shane Cybart (University of California, Riverside, USA), specialist in superconducting devices and director of the UCR Quantum Engineering Center.

●      Olivier De Castro (LIST, Luxembourg), senior scientist in charged particle optics and instrumentation development.

●      Alexandra Fraczkiewicz (CEA-Leti, France), head of the sample preparation group at PFNC’s nanocharacterization platform.

●      Arnaud Houël (Orsay Physics, France), expert in ion source development and FIB technology.

●      Christoph Kastl (Technical University of Munich, Germany), researcher using focused helium-ion beams to engineer van der Waals materials at the atomic scale.

●      Jonathan Gabriel Piccirillo (CNB-CSIC, Spain), developer of cryoFIB-SEM workflows for correlative microscopy.

●      Emeline Raguin (Max Planck Institute, Germany), group leader investigating skeletal tissue formation using FIB-SEM and cryo-microscopy.

●      Elina Zhakina (Max Planck Institute, Germany), postdoctoral researcher focused on 3D superconducting nanostructures for next-generation quantum technologies.

In addition, two invited tutorial speakers delivered in‑depth tutorials complementing the scientific talks.

●      Jack Donoghue (University of Manchester, UK), How to destroy your sample and learn everything you can while doing so. 3D FIB-SEM: A Tutorial.

●      Markus Osenberg (Helmholtz-Zentrum Berlin, Germany), Correlated machine learning assisted FIB tomography on functional materials.

The Evaluation Committee recognised outstanding student contributions with the following awards:

• Best Oral Presentation – 1st Place: Marine Laurencich (Orsay Physics).

• Best Oral Presentation – 2nd Place: Alix Tatiana Escalante Quiceno (Instituto de Nanociencia y Materiales de Aragón, INMA).

• Best Poster (joint winners): Jyoti Verma (Helmholtz‑Zentrum Dresden‑Rossendorf, HZDR) and Juan Ignacio Ocaña (Instituto de Nanociencia y Materiales de Aragón, INMA).

The EU-FIB.net 2025 Workshop not only showcased state-of-the-art advances in Focused Ion Beam technologies but also set the stage for future breakthroughs at the intersection of nanofabrication, quantum science, and advanced microscopy. By bringing together leading voices from academia, industry, and research institutions, the event fostered a vibrant exchange of knowledge and ideas that will continue to shape the field in the years to come. With the European Focused Ion Beam Network and ICMol at the forefront of this initiative, the workshop highlighted Europe’s commitment to driving innovation and strengthening global collaborations in FIB science and technology.
