    Ultra high pressure homogenization (UHPH) opens up new areas for dynamic high pressure assisted thermal sterilization of liquids. Bacillus amyloliquefaciens spores are resistant to high isostatic pressure and temperature ...
  • Georget, Erika; Miller, Brittany; Callanan, Michael John; Heinz, Volker; Mathys, Alexander (Lausanne : Frontiers Media S.A., 2014)
    Bacterial spores have a strong resistance to both chemical and physical hurdles and create a risk for food industry which has been tackled by applying high thermal intensity treatments to sterilize food. These strong thermal ...
  • Swierad, Dariusz; Häfner, Sebastian; Vogt, Stefan; Venon, Bertrand; Holleville, David; Bize, Sebastien; Kulosa, André; Bode, Sebastian; Singh, Yeshpal; Bongs, Kai; Rasel, Ernst Maria; Lodewyck, Jerome; Le Targat, Rodolphe; Lisdat, Christian; Sterr, Uwe (London : Nature Publishing Group, 2016)
    The increasing performance of optical lattice clocks has made them attractive for scientific applications in space and thus has pushed the development of their components including the interrogation lasers of the clock ...
  • Eckert, K.; Zawitkowski, L.; Leskinen, M. J.; Sanpera, A.; Lewenstein, M. (Bristol : IOP Publishing Ltd., 2007)
    We investigate magnetic properties of Mott-insulating phases of ultracold Bose and Fermi spinor gases in optical lattices. We consider in particular the F = 2 Bose gas, and the F = 3/2 and 5/2 Fermi gases. We derive effective ...
  • Greschner, Sebastian; Santos, Luis; Vekua, T. (College Park, MD : American Physical Society, 2013)
    Ultracold bosons in zig-zag optical lattices present a rich physics due to the interplay between frustration induced by lattice geometry, two-body interactions, and a three-body constraint. Unconstrained bosons may develop ...
  • Richter, Florian; Becker, Daniel; Bény, Cédric; Schulze, Torben A.; Ospelkaus, Silke; Osborne, Tobias J. (Bristol : IOP Publishing Ltd, 2015)
    We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key role in driving an ultracold reaction towards ...
  • Oum, Kawon; Lohse, Peter W.; Flender, Oliver; Klein, Johannes R.; Scholz, Mirko; Lenzer, Thomas; Du, Juan; Oekermann, Torsten (Cambridge : Royal Society of Chemistry, 2012)
    The ultrafast photoinjection and subsequent relaxation steps of the indoline dye D149 were investigated in detail for a mesoporous electrodeposited ZnO thin film and compared with experiments on sintered TiO2 and ZrO2 thin ...
  • Kakinuma, Yasuhiro; Ishida, Takuki; Koike, Ryo; Klemme, Heiner; Denkena, Berend; Aoyama, Tojiro (Amsterdam : Elsevier, 2015)
    Carbon fiber-reinforced thermoplastics (CFRTP) are just beginning to be utilized for various applications such as aerospace, automobiles, and sporting goods in place of CFRPs, and the demand for through-hole drilling of ...
  • Lubatschowski, Holger (Amsterdam : Elsevier B.V., 2010)
    Ultrafast laser pulses have become a promising tool for microsurgery of the eye. Due to the low energy threshold, side effects are limited to the micrometer range This precision enables the use of ultrashort laser pulses ...
  • Lohse, Peter W.; Kuhnt, Julia; Druzhinin, Sergey I.; Scholz, Mirko; Ekimova, Maria; Oekermann, Torsten; Lenzer, Thomas; Oum, Kawon (Cambridge : Royal Society of Chemistry, 2011)
    The relaxation dynamics of the indoline dye D149, a well-known sensitizer for photoelectrochemical solar cells, have been extensively characterized in various organic solvents by combining results from ultrafast ...
