The European Spallation Source (ESS) is a European Research Infrastructure Consortium (ERIC), based around what will be the world’s most powerful neutron source. Located in Lund, Sweden, the facility will produce its first neutrons in 2020 and will begin a user programme in 2023. The Deuteration and Macromolecular Crystallisation (DEMAX) platform, part of the Scientific Activities Division, is comprised of chemical and biological deuteration and crystallisation. The chemical deuteration laboratory (DEULAB) at the ESS, housed in Medicon Village, focuses on the synthesis of novel, complex, deuterated small molecules for European neutron users, in collaboration with the other Deuteration Network (DEUNET) partner institutions. The biological deuteration and crystallisation laboratory of ESS is co-housed with the Lund Protein Production Platform (LP3), within Lund University.
Hanna Wacklin-Knecht coordinates the DEUNET, and works in the DEMAX platform developing methods for lipid deuteration and purification from biological cell cultures. Anna Leung is a synthetic chemist in the DEMAX platform, developing methods of chemical and enzymatic synthesis which can be used to produce deuterated small molecules such as lipids, surfactants and monomers for neutron scattering experiments. With the help of Oliver Bogojevic, now pursuing a PhD at the University of Aarhus in Denmark, ESS has developed methods for enzyme-assisted synthesis of chain-deuterated phospholipids. Jenny Andersson (Lund University) joined DEMAX as a post doc in March 2021 to work on lipid purification and analysis for investigations of antimicrobial peptides. Jia-Fei Poon (Lund University/ESS) works on the synthesis of novel surfactants for use in food and medical applications.
Zoë Fisher is the DEMAX group leader and works in the areas of biological deuteration and macromolecular crystallisation, producing partially or perdeuterated macromolecules for neutron scattering.

The D-lab assists external users wishing to make their own deuterated biological molecules for use in neutron scattering experiments. The L-Lab provides a number of hydrogenous and deuterated lipids, purified from natural extracts of yeasts and bacteria.
Giovanna Fragneto is the head of the SMSS and LSS (Large Scale Structures) groups. Her research focuses on the structural characterization and fluctuations of model biological membranes using neutron and X-ray reflectometry with aim of understanding phenomena at cell surfaces. Examples include the interaction of membranes with peptides, proteins, drugs or drug delivery systems. Krishna Batchu is the scientist responsible for L-Lab activities within the Partnership for Soft Condensed Matter (PSCM) initiative – a joint effort between the ILL and the European Synchrotron Radiation Facility (ESRF). ILL member of staff involved in lipid production and characterisation include instrument scientists Anne Martel, Lionel Porcar, Sylvain Prevost, Bruno Demé from the LSS group, scientist Michael Haertlein and technician Valerie Laux from the D-Lab, and students Giacomo Corucci, Andreas Santamaria, Moritz Frewein from LSS and SMSS.
