      In situ observation of rapid reactions in nanoscale Ni-Al multilayer foils using synchrotron radiation 

      Fadenberger, K.; Gunduz, Ibrahim Emre; Tsotsos, Chrysostomos; Kokonou, Maria; Gravani, S.; Brandstetter, Stefan; Bergamaschi, Anna; Schmitt, Bernd; Mayrhofer, Paul H.; Doumanidis, C. C.; Rebholz, Claus (2010)
      The observation of rapid reactions in nanoscale multilayers present challenges that require sophisticated analysis methods. We present high-resolution in situ x-ray diffraction analysis of reactions in nanoscale foils of ...

      Investigations on the self propagating reactions of nickel and aluminum multilayered foils 

      Gunduz, Ibrahim Emre; Fadenberger, K.; Kokonou, Maria; Rebholz, Claus; Doumanidis, C. C. (2008)
      The self-propagating reaction of nickel-aluminum thin film multilayers with a bilayer thickness of 43 nm was investigated using high-speed optical camera and infrared thermometry. The results indicate a two-stage reaction ...

      Synthesis of reactive Al/Ni structures by ball milling 

      Hadjiafxenti, Anastasia; Gunduz, Ibrahim Emre; Tsotsos, Chrysostomos; Kyratsi, Theodora; Doumanidis, C. C.; Rebholz, Claus (2010)
      Material systems that exhibit self-propagating exothermic reactions (SPER) can be potentially used for nano/microscale heater purposes in thermal nanomanufacturing applications. We propose that ball milling (BM) is a simple ...

      Underwater Robotic Welding of Lap Joints with Sandwiched Reactive Multilayers: Thermal, Mechanical and Material Analysis 

      Hussein, Aseel; Alkhoori, Ayesha; Zaabi, Abdelaziz Al; Stefanini, Cesare; Renda, Federico; Jaffar, Syed; Gunduz, Ibrahim Emre; Polychronopoulou, Kyriaki; Rebholz, Claus Georg; Doumanidis, Charalabos Constantinos (2018)
      Underwater welding using reactive materials pre-deposited at the junction surfaces as a self-contained, in-situ ignitable heat source mitigates external power and gas supply requirements. Consequently, lending itself to ...
