A compact high resolution ion mobility spectrometer for fast trace gas analysis

Kirk, Ansgar T.; Allers, Maria; Cochems, Philipp; Langejuergen, Jens; Zimmermann, Stefan (Cambridge : Royal Society of Chemistry, 2013)

Drift tube ion mobility spectrometers (IMS) are widely used for fast trace gas detection in air, but portable compact systems are typically very limited in their resolving power. Decreasing the initial ion packet width ...
Fischzähne aus dem Oberjura Nordwesteuropas : Systematik, Biogeochemie und Palökologie

Mudroch, Alexander (Hannover : Universität, 2001)

I-Type Cosmic Spherules as Proxy for the Δ′17O of the Atmosphere—A Calibration With Quraternary Air

Fischer, Meike B.; Oeser, Martin; Weyer, Stefan; Folco, Luigi; Peters, Stefan T. M.; Zahnow, Fabian; Pack, Andreas (Hoboken, NJ : Wiley, 2021)

Remnants of shooting stars are preserved in form of cosmic spherules in ice and sediments. The extraterrestrial material is heated and melted upon atmospheric entry and is collected at the Earth's surface as cosmic spherules. ...
Plutonium release from Fukushima Daiichi fosters the need for more detailed investigations

Schneider, Stephanie; Walther, Clemens; Bister, Stefan; Schauer, Viktoria; Christl, Marcus; Synal, Hans-Arno; Shozugawa, Katsumi; Steinhauser, Georg (Lausanne : Frontiers Research Foundation, 2013-10-18)

The contamination of Japan after the Fukushima accident has been investigated mainly for volatile fission products, but only sparsely for actinides such as plutonium. Only small releases of actinides were estimated in ...
Six-fold-symmetry internal rotation in toluenes: the low barrier challenge of 2,6-and 3,5-difluorotoluene

Nair, K. P. Rajappan; Jahn, Michaela K.; Lesarri, Alberto; Ilyushin, Vadim V.; Grabow, Jens-Uwe (Cambridge : Royal Society of Chemistry, 2015-09-22)

Pure six-fold symmetry (V6) internal rotation poses significant challenges to experimental and theoretical determination, as the very low torsional barriers result in huge tunneling splittings difficult to identify and to ...
Spatial patterns of erosion and landscape evolution in a bivergent metamorphic core complex revealed by cosmogenic 10Be: The central Menderes Massif (western Turkey)

Heineke, Caroline; Hetzel, Ralf; Nilius, Nils-Peter; Glotzbach, Christoph; Akal, Cüneyt; Christl, Marcus; Hampel, Andrea (McLean, Va : GeoScienceWorld (GSW), 2019)

In extensional provinces with low-angle normal faulting (such as the Aegean region), both tectonic processes and erosion induce landscape change, but their interaction during the evolution of topography and relief accompanying ...
Unravelling the importance of mycorrhiza for plant nitrogen nutrition and transfer into the networks

Fernandes Figueiredo, Aline (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)

Most terrestrial plants establish symbiotic associations with fungi called mycorrhiza, like ectomycorrhizas (EM) and arbuscular mycorrhizas (AM), for accessing limiting plant nutrients. For improving N nutrition, some plant ...
Die Zustandsgleichung isotoper Äthylene

Dorfmüller, T.; Göpel, W. (Berlin, Boston : De Gruyter, 1969)

The second virial coefficients of C2H4 and C.D4 have been measured at 236.04 K. The experimental isotope etlect of 1.07% can he separated into one contribution from a translational quantum effect and one contribution which ...
