  • Melchers, Stephanie; Schneider, Jenny; Emeline, Alexei V.; Bahnemann, Detlef W. (Basel : MDPI AG, 2018)
    The effect of H2O and O2 on the adsorption and degradation of gaseous acetaldehyde on the anatase TiO2 surface has been studied, in the dark and upon UV illumination, at ambient temperatures. The processes occurring at the ...
  • Voronkov, Vladimir V.; Falster, Robert; Batunina, A.V.; MacDonald, D.; Bothe, Karsten; Schmidt, J. (London : Elsevier Ltd., 2011)
    The recombination centre that emerges in boron- and oxygen-containing silicon was thought to be a complex of a substitutional boron atom Bs and an oxygen dimer O2. However in material co-doped with boron and phosphorus, ...
  • Dillert, Ralf; Engel, Astrid; Große, Julia; Lindner, Patrick; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2013)
    Air pollution by nitrogen oxides represents a serious environmental problem in urban areas where numerous sources of these pollutants are concentrated. One approach to reduce the concentration of these air pollutants is ...
  • Voronkov, Vladimir V.; Falster, Robert; Bothe, Karsten; Lim, Bianca (London : Elsevier Ltd., 2013)
    Light-induced electron lifetime degradation in boron-doped Czochralski silicon was studied before and after a prolonged annealing at 350°C (up to 120 h) and 300°C (up to 8 weeks). Such a heat treatment is known to reduce ...
  • Bothe, Karsten; Ramspeck, K.; Hinken, D.; Schinke, Carsten; Schmidt, J.; Herlufsen, S.; Brendel, Rolf; Bauer, J.; Wagner, J.-M.; Zakharov, N.; Breitenstein, O. (College Park, MD : American Institute of Physics, 2009)
    We study the emission of light from industrial multicrystalline silicon solar cells under forward and reverse biases. Camera-based luminescence imaging techniques and dark lock-in thermography are used to gain information ...
  • Schmitz, Gerd; Mohammadi, Bahram; Hammer, Anke; Heldmann, Marcus; Samii, Amir; Münte, Thomas F.; Effenberg, Alfred O. (London : BioMed Central Ltd., 2013)
    Background: Producing sounds by a musical instrument can lead to audiomotor coupling, i.e. the joint activation of the auditory and motor system, even when only one modality is probed. The sonification of otherwise mute ...
  • de Vries, Ingo; Busse, Christoph; Kopatz, Jens; Neumann, Harald; Beutel, Sascha; Scheper, Thomas (Weinheim : Wiley-VCH Verlag, 2017)
    Polysialic acid (polySia), consisting of α-(2,8)-linked N-acetylneuraminic acid monomers plays a crucial role in many biological processes. This study presents a novel process for the production of endogenous polySia using ...
  • Prante, Marc; Ude, Christian; Große, Miriam; Raddatz, Lukas; Krings, Ulrich; John, Gernot; Belkin, Shimshon; Scheper, Thomas (Basel : MDPI AG, 2018)
    Buried explosive material, e.g., landmines, represent a severe issue for human safety all over the world. Most explosives consist of environmentally hazardous chemicals like 2,4,6-trinitrotoluene (TNT), carcinogenic ...
  • Leschke, Jan; Barroi, Alexander; Kaierle, Stefan; Hermsdorf, Jörg; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2016)
    In this paper, an underwater laser cutting process for maintenance and replacement operations is presented and investigated regarding process robustness for the application in rough environments. A Yb:YAG laser is used ...
  • Murphy, J.D.; Al-Amin, M.; Bothe, K.; Olmo, M.; Voronkov, V.V.; Falster, R.J. (College Park, MD : American Institute of Physics, 2015)
    Supersaturated levels of interstitial oxygen in Czochralski silicon can lead to the formation of oxide precipitates. Although beneficial from an internal gettering perspective, oxygen-related extended defects give rise to ...
  • Rafti, M.; Uecker, H.; Lovis, F.; Krupennikova, V.; Imbihl, R. (Cambridge : Royal Society of Chemistry, 2012)
    A new type of traveling interface modulation has been observed in the NH 3 + O 2 reaction on a Rh(110) surface. A model is set up which reproduces the effect, which is attributed to diffusional mixing of two spatially ...
  • Steckenreiter, V.; Walter, D.C.; Schmidt, J. (London : Elsevier Ltd., 2017)
    We analyze the lifetime evolution during permanent deactivation of the boron-oxygen-related defect center (BO defect) in boron-doped, oxygen-rich Czochralski-grown silicon (Cz-Si). In particular, we examine the impact of ...
