Structure of the water channel AqpZ from Escherichia coli revealed by electron crystallography

Henning Paul-Julius Stahlberg, Andreas Engel

Molecular water channels (aquaporins) allow living cells to adapt to osmotic variations by rapid and specific diffusion of water molecules. Aquaporins are present in animals, plants, algae, fungi and bacteria. Here we present an electron microscopic analys ...

Ice-core record of atmospheric methane changes: relevance to climatic changes and possible gas hydrate sources

Jérôme Chappellaz

Environmental conditions prevailing during build-up of the Greenland Ice Sheet (GIS) are not yet established. Here we use results from gas isotopes from basal ice of the GRIP ice core to show that central Greenland was vegetated during invasion by the ice ...

Periodic operation applied to kinetic studies of CO2-methanation

Albert Renken

Periodic operation was applied to the CO2 methanation reaction at 383 K on 2% Ru/TiO2. A continuous feed recycle reactor combined with a diffuse reflectance infrared cell and a mass spectrometer allowed to follow simultaneously the gas phase CO2 and CH4 as ...
