    • Iron speciation in blast furnace slag cements 

      Mancini, A.; Lothenbach, Barbara; Geng, G.; Grolimund, D.; Sanchez, D.F.; Fakra, Sirine C.; Dähn, R.; Wehrli, B.; Wieland, E. (Peer reviewed; Journal article, 2021)
      Slag-containing pastes and concretes were analysed by element-specific synchrotron-based techniques to determine the speciation of iron on crushed materials through spatially resolved micro-spectroscopic studies. The ...

    • X-ray Microprobe Investigation of Iron During a Simulated Silicon Feedstock Extraction Process 

      Bernardis, Sarah; Fakra, Sirine C.; Dal Martello, Elena; B. Larsen, Rune; Newman, Bonna K.; Fenning, David P.; Di Sabatino Lundberg, Marisa; Buonassisi, Tonio (Peer reviewed; Journal article, 2016)
      Elemental silicon is extracted through carbothermic reduction from silicon-bearing raw feedstock materials such as quartz and quartzites. We investigate the micron-scale distribution and valence state of iron, a deleterious ...
