Rapid oxidation of geothermal arsenic(III) in streamwaters of the eastern Sierra Nevada

Arsenic redox cycling was examined in source waters of the Los Angeles Aqueduct, specifically at Hot Creek, a tributary of the Owens River. Elevated arsenic concentrations in Hot Creek result from geothermal inputs. Total arsenic and As(III) concentrations ...

Study of the reduction of nitrogen oxides with CO and H2 on Pt-Mo catalysts in the oxidizing range

Albert Renken

The redn. of NOx with CO and H2 on Pt-Mo/a-Al2O3 catalysts as an alternative for Pt-Rh catalysts was studied for exhaust gas purifn. in lean-mixed engines in oxidizing range. The NOx content has a significant influence on the catalyst activity. The H2/O2 r ...

Investigation of the Reduction of Nitric Oxides by CO and H2 on Pt-Mo Catalysts under Oxidizing Conditions

Albert Renken

The reduction of NO by CO on Pt has been extensively investigated in the past since it helps to eliminate NO of the exhaust gas of cars. However, the dissociation of NO in this reaction and the deactivation of the NO/CO reaction on Pt-supported catalysts s ...

Batch cultures of a hybridoma cell line performed with in situ ammonia removal

Urs von Stockar, Ian William Marison, Markus Schneider

Batch cultures of a mouse/mouse hybridoma cell line secreting a dimeric IgA were performed in combination with a membrane process for the continuous removal of ammonia from the culture medium. The latter involves hydrophobic porous membranes with an assocd ...

Na Hyperoxidation States Studied by Core-Level Spectroscopy

Giorgio Margaritondo

In order to investigate the formation and the time evolution of Na oxidation states, a thin ayer 0 sodium was deposited on oxidized substrates and exposed to oxygen at 10(-9) Torr. In the Na 2p core-level spectrum, several chemically shifted components hav ...
