    In this study, the contact formation of aluminum containing silver metallization pastes for boron emitters was investigated. Model pastes with varied glass composition (PbO-containing and PbO-free) and Al content were ...
  • Busch, Jan; Schmidt, Maurice; Nyhuis, Peter (2015)
    The change of conditions for production companies in high-wage countries is characterized by the globalization of competition and the transition of a supplier´s to a buyer´s market. The companies need to face the challenges ...
  • Tornow, Alexander; Raatz, Annika; Dröder, Klaus (Amsterdam : Elsevier, 2014)
    Battery systems of electric vehicles suffer from low energy densities as well as high masses and geometrical complexity. The absence of standards for battery cells and peripheral components in combination with large and ...
