Infrared spectroscopy (FTIR) is a well-established analytical tool able to retrieve chemical properties of material based on their intrinsic vibrational signatures. High chemical sensitivity in a label-free environment combined to low-cost operation feature FTIR as a versatile and accessible multidisciplinary tool. In the past few decades, the implementation of FTIR in synchrotron facilities allowed for an unprecedented sensitivity for micro-scale chemical imaging due to the superior spectral irradiance of those light sources in the energy range from near-IR up to THz. Moreover, the improved brightness of synchrotrons made feasible new spectral-imaging modalities such as ultra-broadband IR nano-spectroscopy, a unique technique able to unveil chemistry and optics of materials in the nanoscale.

The MIRCA workshop aims to bring a quick update on the latest developments in the theme of IR ultra-microscopy as well as it targets to provide guidance to professors, researchers and students on sample requirements, data processing tools and sample preparation procedures related to those new experimental modalities. After the series of talks we expect the attendants to be motivated to identify potential scientific cases that could benefit from those new capabilities that will be available in the IMBUIA beamline, the new IR station to be installed in the SIRIUS accelerator.

Invited Speakers

Dr. Hans Bechtel

Beamline Scientist at the infrared beamlines in the Advanced Light Source (ALS) – Berkeley/USA.

PhD in Physical Chemistry at the Stanford University, Dr. Hans Bechtel has made seminal contributions in advanced synchrotron infrared spectral imaging, including 3D infrared tomography and scattering Near-Field Optical Microscopy using synchrotron infrared. From chemistry of living cells up to the properties of polaritons in polar crystals, Dr. Bechtel has contributed to outstanding recent discoveries as ultra-resolved mapping of catalytic reactions on single nano-particles and infrared vibrational nanocrystallography.

Dr. Carol Hirschmugl

Professor of Physics at the University of Wisconsin at Milwaukee, principal Investigator at the Synchrotron Radiation Center, and Director of the Laboratory for Dynamics and Structure at Surfaces

Carol Hirschmugl received her BSc in Physics from State University of New York at StonyBrook in 1987 and her Applied Physics PhD from Yale University in 1994. She then received an Alexander von Humboldt grant to do research at Fritz Haber Institut, Berlin, from 1994 to 1996. In 1996, she was awarded the University of California President’s Postdoctoral Fellowship to work at Lawrence Berkeley National Laboratory. Since 1997, Hirschmugl has been at the University of Wisconsin-Milwaukee, where she is a professor at the Physics Department and the Director of the Laboratory for Dynamics and Structure at Surfaces. She studies the surface physics of adsorbates on epitaxial and bulk oxide systems, focusing on environmentally and technologically relevant problems.


Dr. Ferenc Borondics

Principal beamline scientist at the SMIS infrared spectromicroscopy beamline in the Soleil Synchrotron – Paris/France.

PhD in Inorganic Chemistry at the Eötvös Loránd University (Budapest/Hungary), Dr. Ferenc Borondics has built a solid career in vibrational spectroscopy with relevant contributions in the fields of condensed matter physics, optics, advanced spectroscopy methods and nanoscience. Lately, he is leading a project on the implementation of synchrotron infrared nanospectroscopy via photo-thermal expansion and is one of the main contributors for the developing of new open-source tools for infrared spectral-imaging data.


Dr. Victoria Beltran

Chemist – Postdoctoral researcher at the French National Centre for Scientific Research | CNRS · IPANEMA

PhD in Analytical Chemistry in Polytechnic University of Catalonia (Spain) in collaboration with the Restoration Center of Movable Goods of Catalonia (Spain) centred in the study of organic coatings in paintings and altarpieces by means of vibrational spectroscopies. Postdoctoral project focused in the study of varnishes from historical musical instruments by infrared spectroscopy and synchrotron based research in Ipanema (France), a laboratory for the development of advanced methodologies of material characterization in archaeology, paleo-environments, paleontology and cultural heritage.

This is a satellite event to the 28th edition of the Annual Users Meeting (RAU).
