  • Burkholderiaceae Are Key Acetate Assimilators During Complete Denitrification in Acidic Cryoturbated Peat Circles of the Arctic Tundra 
    Hetz, Stefanie A.; Horn, Marcus A. (Lausanne : Frontiers Media, 2021)
    Cryoturbated peat circles (pH 4) in the Eastern European Tundra harbor up to 2 mM pore water nitrate and emit the greenhouse gas N2O like heavily fertilized agricultural soils in temperate regions. The main process yielding ...
  • Electron transport through low-dimensional carbon-based systems 
    Slawig, Diana (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Carbon-based materials in all their facets yield an extremely large area of electronic applications. Its quasi-unlimited availability, wide ranging tuneability and scalability make them a potent rival to the currently ...
  • Impurity effects in quantum dots: Toward quantitative modeling 
    Räsänen, E.; Könemann, J.; Haug, Rolf J.; Puska, M.J.; Nieminen, R.M. (College Park, MD : American Physical Society, 2004)
    We have studied the single-electron transport spectrum of a quantum dot in GaAs/AlGaAs resonant tunneling device. The measured spectrum has irregularities indicating a broken circular symmetry. We model the system with an ...
  • The Oxidative Phosphorylation system of the mitochondria in plants 
    Braun, Hans-Peter (Amsterdam [u.a.] : Elsevier Science, 2020)
    Mitochondrial Oxidative Phosphorylation (OXPHOS) provides ATP for driving cellular functions. In plants, OXPHOS takes place in the context of photosynthesis. Indeed, metabolism of mitochondria and chloroplasts is tightly ...
  • Phonons in InAs/AlAs single quantum dots observed by optical emission 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Becker, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2005)
    Photoluminescence emission spectra of self-assembled single InAs/AlAs quantum dots with variable size reveal typical sharp lines below 1.8 eV, corresponding to transitions between fully confined states. Above this energy ...
  • Photo-excited charge transfer from adamantane to electronic bound states in water 
    Wang, Xiangfei; Krause, Pascal; Kirschbaum, Thorren; Palczynski, Karol; Dzubiella, Joachim; Bande, Annika (Cambridge : RSC Publ., 2024)
    Aqueous nanodiamonds illuminated by UV light produce free solvated electrons, which may drive high-energy reduction reactions in water. However, the influence of water conformations on the excited-state electron-transfer ...
  • Probing cytochrome c in living mitochondria with surface-enhanced Raman spectroscopy 
    Brazhe, Nadezda A.; Evlyukhin, Andrey B.; Goodilin, Eugene A.; Semenova, Anna A.; Novikov, Sergey M.; Bozhevolnyi, Sergey I.; Chichkov, Boris; Sarycheva, Asya S.; Baizhumanov, Adil A.; Nikelshparg, Evelina I.; Deev, Leonid I.; Maksimov, Eugene G.; Maksimov, Georgy V.; Sosnovtseva, Olga (London : Nature Publishing Group, 2015)
    Selective study of the electron transport chain components in living mitochondria is essential for fundamental biophysical research and for the development of new medical diagnostic methods. However, many important details ...
  • Shot-noise at a Fermi-edge singularity: Non-Markovian dynamics 
    Ubbelohde, Niels; Roszak, K.; Hohls, Frank; Maire, Niels; Novotný, T.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    For an InAs quantum dot we study the current shot noise at a Fermi-edge singularity in low temperature cross-correlation measurements. In the regime of the interaction effect the strong suppression of noise observed at ...
  • A structural model of the cytochrome c reductase/oxidase supercomplex from yeast mitochondria 
    Heinemeyer, Jesco; Braun, Hans-Peter; Boekema, Egbert J.; Kouřil, Roman (Bethesda, Md. : ASBMB Publications, 2007)
    Mitochondrial respiratory chain complexes are arranged in supercomplexes within the inner membrane. Interaction of cytochrome c reductase (complex III) and cytochrome c oxidase (complex IV) was investigated in Saccharomyces ...
  • Supramolecular structure of the mitochondrial oxidative phosphorylation system 
    Boekema, Egbert J.; Braun, Hans-Peter (Bethesda, Md. : ASBMB Publications, 2007)
    The protein complexes of the mitochondrial oxidative phosphorylation system were recently reported to form supramolecular assemblies termed respiratory supercomplexes or respirasomes. These supercomplexes are considered ...
  • Supramolecular structure of the OXPHOS system in highly thermogenic tissue of Arum maculatum 
    Sunderhaus, Stephanie; Klodmann, Jennifer; Lenz, Christof; Braun, Hans-Peter (Amsterdam [u.a.] : Elsevier Science, 2010)
    The protein complexes of the mitochondrial respiratory chain associate in defined ways forming supramolecular structures called respiratory supercomplexes or respirasomes. In plants, additional oxidoreductases participate ...
