The Radiation Surface Science and Engineering Laboratory (RSSEL) group headed by Prof. J.P. Allain focuses on the design of self-organized nanostructures with two techniques he has pioneered: directed irradiation synthesis (DIS) and directed plasma nanosynthesis (DPNS). Both approaches are used to enable multi-functional and multi-scale properties at surface and interfaces of dissimilar material systems (e.g. polymer and metals, ceramics and biomaterials). RSSEL research themes include: advanced functional biointerfaces, advanced fusion interfaces, multi-scale computational irradiation surface science, nanostructured functional materials, sustainable nanomanufacturing, and in-situ, in-operando diagnostics.
