Three student research papers suggest that amino acids and a bone mineral called hydroxyapatite may help control the breakdown of magnesium implants. These findings, published in scientific journals, come from the research group of Elsebeth Schröder at the Division of Quantum Device Physics. It is uncommon for a bachelor's thesis to be published in a scientific journal, and even rarer for three such theses from the same research group to be published within three months. To celebrate this achievement, Schröder invited all three student teams to a cake party at the Department of Microtechnology and Nanoscience. Alva Limbäck, along with Olof Hildeberg, John Bolin, and Amanda Goold, published an article titled "A density functional theory study of amino acids on pristine Mg(0001) and with sparse alloying elements" in Applied Surface Science in August. Their study investigated how amino acids such as glycine, proline, and hydroxyproline—naturally present in collagen—might help form a protective layer on the surface of magnesium implants. The results suggest that these amino acids can contribute to creating a protective surface coating, particularly when magnesium contains small amounts of other metals. In another study, Miranda Naurin, Sally Aldhaim, Moltas Elliver, Ludwig Hagby, and Didrik Nilsson published "Toward an understanding of magnesium in a biological environment: A density functional theory study" in AIP Advances. Their work focused on how biological molecules interact with the implant surface and how these interactions may influence the degradation process. They examined how magnesium and magnesium hydroxide interact in a biological environment, noting that magnesium hydroxide does not bind strongly to the magnesium surface and can move relatively freely across it. They also found that the bond between different magnesium hydroxide layers is stronger than the bond between the hydroxide and the magnesium surface itself, suggesting that magnesium hydroxide tends to detach in clusters rather than dissolving layer by layer. Anthony Veit Berg, Ablai Forster, Tim Hansson, Alex J. Jernstedt, and Emmy Salminen published "First-principles study of the influence of hydroxyapatite on magnesium surfaces" in Physical Chemistry Chemical Physics. Their study examined how hydroxyapatite, a mineral naturally found in bones and teeth, binds to the surface of magnesium-based implants. They studied both pure magnesium and magnesium containing small amounts of calcium or zinc, finding that both calcium and zinc generally strengthened the interaction between hydroxyapatite and magnesium, although the effect depended on where the surface was doped. All three groups used density functional theory (DFT) simulations in their studies, a computational method used to model the electronic structure of materials. The students attribute the success of the publications to a combination of strong scientific results, effective teamwork, and dedicated supervision. Several of the students are now pursuing master's studies, and many are planning careers in industry after graduation. The experience of publishing scientific research appears to have sparked a growing interest in academia among the students.
