Nano- & Micro-Joining

Following the trends of miniaturization, diversification and functionalization, there is an urgent need for novel joining concepts to integrate, package and assemble a high number of micro- and nano-scale devices at ever-lower temperatures. To address these demands, we conduct research on nano-structured materials and explore the potential of using nano-effects for nano-/microjoining technologies. Our lab is renowned for its pioneering work on the development of nano-structured brazing fillers and its use of reactive nanomultilayers for room-temperature joining processes (→ our services).  Together with our international partners, we are actively shaping the field of Nano-/Microjoining as a new scientific discipline and technology.


  • Diffusion, wetting, nucleation, (pre)melting and (metastable) phase formation at reacting surfaces and interfaces in nanostructured materials and coating systems ( Advanced Joining)

  • Interfacial design and fabrication of nano-structured fillers, reactive nanomultilayers and nano-thermites by physical vapour deposition and chemical synthesis techniques

  • Synthesis of nanoparticle-based pastes and mechanisms of nanopaste sintering for joining

  • Real-time in-situ monitoring of microstructural evolutions and reactions kinetics at reacting interfaces in nano-materials by laboratory- and synchrotron-based techniques (e.g. in-situ XRD, XAS, TEM, SEM, HAXPES/XPS and AES)

  • Development of new joining procedures for integrating, packaging and assembling micro- and nano-scale devices
