      Büscher, Julia; Mirone, Alessandro; Stękiel, Michał; Spahr, Dominik; Morgenroth, Wolfgang; Haussühl, Eiken; Milman, Victor; Bosak, Alexei; Ivashko, Oleh; von Zimmermann, Martin; Dippel, Ann-Christin; Winkler, Björn (Journal of Applied Crystallography, 2021-01-29)
      The complete elastic stiffness tensor of thiourea has been determined from thermal diffuse scattering (TDS) using high‐energy photons (100 keV). Comparison with earlier data confirms a very good agreement of the tensor ...
    • Formation of chondrule analogs aboard the International Space Station 

      Koch, Tamara E.ORCIDiD; Spahr, Dominik; Tkalcec, Beverley J.ORCIDiD; Lindner, MilesORCIDiD; Merges, David; Wilde, Fabian; Winkler, Björn; Brenker, Frank E.ORCIDiD (Meteoritics & Planetary Science, 2021-08-21)
      Chondrules are thought to play a crucial role in planet formation, but the mechanisms leading to their formation are still a matter of unresolved discussion. So far, experiments designed to understand chondrule formation ...
    • Formation of fused aggregates under long‐term microgravity conditions aboard the ISS with implications for early solar system particle aggregation 

      Koch, Tamara E.ORCIDiD; Spahr, Dominik; Tkalcec, Beverley J.ORCIDiD; Christ, Oliver; Genzel, Philomena‐Theresa; Lindner, MilesORCIDiD; Merges, David; Wilde, Fabian; Winkler, Björn; Brenker, Frank E.ORCIDiD (Meteoritics & Planetary Science, 2022-04-21)
      In order to gain further insights into early solar system aggregation processes, we carried out an experiment on board the International Space Station, which allowed us to study the behavior of dust particles exposed to ...
    • Pressure‐induced Pb–Pb bonding and phase transition in Pb2SnO4 

      Spahr, Dominik; Stękiel, Michał; Zimmer, Dominik; Bayarjargal, Lkhamsuren; Bunk, Katja; Morgenroth, Wolfgang; Milman, Victor; Refson, Keith; Jochym, Dominik; Byrne, Peter J. P.; Winkler, Björn (Acta Crystallographica Section B, 2020-11-11)
      High‐pressure single‐crystal to 20 GPa and powder diffraction measurements to 50 GPa, show that the structure of Pb2SnO4 strongly distorts on compression with an elongation of one axis. A structural phase transition occurs ...
    • Synthesis, crystal structure and structure–property relations of strontium orthocarbonate, Sr2CO4 

      Laniel, Dominique; Binck, Jannes; Winkler, Björn; Vogel, Sebastian; Fedotenko, Timofey; Chariton, Stella; Prakapenka, Vitali; Milman, Victor; Schnick, Wolfgang; Dubrovinsky, Leonid; Dubrovinskaia, Natalia (Acta Crystallographica Section B, 2021-02-09)
      Carbonates containing CO4 groups as building blocks have recently been discovered. A new orthocarbonate, Sr2CO4 is synthesized at 92 GPa and at a temperature of 2500 K. Its crystal structure was determined by in situ ...
