Simulation of Stratospheric Water Vapor Trends: Impact on Stratospheric Ozone Chemistry [PDF]
, 2005 A transient model simulation of the 40-year time period 1960 to 1999 with the coupled climate-chemistry model (CCM) ECHAM4.L39(DLR)/CHEM shows a stratospheric water vapor increase over the last two decades of 0.7 ppmv and, additionally, a short-term ...

Autocatalytic and cooperatively-stabilized dissociation of water on a stepped platinum surface
, 2012 Water-metal interfaces are ubiquitous and play a key role in many chemical processes, from catalysis to corrosion. Whereas water adlayers on atomically flat transition metal surfaces have been investigated in depth, little is known about the chemistry of

Quantifying physiological influences on otolith microchemistry [PDF]
, 2015 Trace element concentrations in fish earstones (‘otoliths’) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumption that physiological influences on otolith composition are minor ...

Water destruction by X-rays in young stellar objects
, 2006 We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemistry is modeled as a function of time, hydrogen density and X-ray flux. To
