Shared services: an ecosystem serving science

There are a number of shared services on the campus, serving the laboratories. These entities, which are less in the limelight on a day-to-day basis, are nevertheless necessary for the smooth running of the campus and play a major role in the results obtained by the laboratories, which are responsible for scientific publications.

Some services cannot be provided unilaterally by the laboratories, in particular because of the very high cost of certain analytical instruments or the highly specialised skills required to operate them. It is also important to emphasise the important work carried out by the technical, administrative and operational teams linked to the campus. These services are briefly described below, and the people involved can be found HERE:

How the campus works

The Valais campus is fortunate to be housed in recent, high-quality buildings provided by the State of Valais. However, the extremely complex environment in which most of the laboratories operate requires technical, administrative, security and operational services to be provided on a daily basis in these buildings. The central services of the Valais campus include these various trades, without which the campus would come to a standstill. From managing ventilation and toxic gas evacuation problems to installing new laboratories and managing alarms, the team in place manages an impressive array of different tasks. They often work in the shadows, but their existence is quickly brought to the fore whenever something stops working or needs improving.

Electron microscopy (CIME)

The CIME is a central electron microscopy platform dedicated to research in solid state physics, materials science and life sciences. It brings together most of EPFL’s electron microscopy equipment and an experienced team. This organisation makes it possible to offer a wide range of observation techniques while limiting the investment required.

CIME offers anyone interested in electron microscopy – researchers, EPFL students, staff from other universities or private laboratories – access to the methods best suited to their needs.

CIME also carries out its own research and development activities, in order to maintain a high level of expertise and keep in touch with users.

Analysis laboratories (GR-CEL)

The Central Environmental Laboratory (CEL) carries out research and provides services in the fields of environmental analytical chemistry and molecular biology. Headed by Florian Breider, the CEL brings together laboratory technicians, apprentices and senior researchers. Its work focuses mainly on the fate of micro-pollutants and nano- or micro-plastics in aquatic and terrestrial environments, the development of cutting-edge analytical methods for detecting organic and inorganic pollutants, and the role of micro-organisms in natural and man-made environments.

The CEL provides services, teaching, training and technical support to all the research groups associated with the Institute of Environmental Engineering (IIE), as well as to employees of the ENAC faculty and other EPFL schools.

X-ray diffraction and surface analysis platform (ISIC-XRDSAP)

EPFL’s X-ray diffraction and surface analysis platform provides researchers with a wide range of techniques for studying materials. It enables the crystalline structure, chemical composition and surface properties of a wide range of samples to be examined.

Our services cover standard analyses, accessible to all users, as well as more complex experiments defined according to the specific needs of projects. The team also offers support in choosing the most appropriate methods, particularly for people unfamiliar with these techniques.

The main activities include X-ray diffraction (to determine the structure and microstructure of materials, their phases or textures), reflectometry (to measure the thickness of thin layers), as well as surface analyses using electronic spectroscopy (XPS, UPS, Auger) and Raman spectroscopy. These approaches provide detailed information on the composition, chemical state, atomic organisation and evolution of samples over time.

Mass spectrometry and elemental analysis platform (ISIC-MSEAP)

EPFL’s mass spectrometry and elemental analysis platform (ISIC-MSEAP) offers a wide range of technologies for analysing small organic molecules, large biomolecules and metallic elements.

Thanks to the diversity of its ionisation and detection techniques, the platform offers very high-precision analyses of the composition, structure and interactions of the substances studied. It also has recognised expertise in ‘Top-Down’ proteomics (direct analysis of intact proteins) and in ‘Native’ mass spectrometry, used to study protein complexes in their natural form.

The platform provides services and scientific support to research groups at ISIC and EPFL, as well as to external academic and industrial partners. Users can access the instruments after specific training, or entrust their samples to the team as part of an analysis service or research collaboration.

Shops

Laboratories are in constant need of equipment, from simple lab coats to more complex chemical reagents. Specialists are on hand at the Valais campus to supply them with exactly what they need, on time.

There are two shops. One is attached to the SB faculty, via ISIC, and is located in building I17. The other, more recent, is attached to the ENAC faculty and is located in the ALPOLE building. The warehousemen are also responsible for receiving all incoming goods and parcels, managing the security of the various materials received and dealing with their disposal. They are an essential link in the scientific chain.

Mechanical and electronic workshops

In order to carry out their experiments, laboratories need equipment that is sometimes ‘made to measure’. The mechanical and electronics workshops are there to provide it. From the part used to wedge a laser to the chassis supporting a reversible oxide battery, our workshop specialists are there to be creative and deliver quality results. They have a wide range of machines at their disposal, including milling machines, lathes, laser engravers and welding stations. They play an integral part in the design of the parts by discussing them with the researchers, and are responsible for their production. They are the magic hands in the laboratories, enabling experiments of all kinds to be carried out.

They are organised on two sites, one workshop attached to the SB faculty, via ISIC, and is located in building I17. The other, more recent, is attached to the ENAC faculty and is located in the ALPOLE building. These two workshops are complementary and mutually supportive, forming an integral part of the Valais campus ecosystem.

IT services

All the laboratories at Sion make extensive use of IT tools to process the data collected in the field or for purely computational modelling. IT specialists are on campus to support them in all these digital aspects. From the installation of workstations for new arrivals to the very specific coding of platforms used by laboratories, the range of their services is very wide.
