Laboratory studies on the production of alpha-pinene-derived organic nitrates and their atmospheric fate
<p>Currently, the formation yields of organic nitrates from the oxidation of biogenic volatile organic compounds, such as α-pinene, is highly uncertain, negatively impacting our knowledge on tropospheric ozone production and the fate of atmospheric NO<sub>x</sub>. To lower this uncertainty, we …

Understanding the formation of secondary organic aerosol and the fates of organic nitrates formed from monoterpene oxidation
Secondary organic aerosol (SOA) contributes to a substantial fraction of fine particular matter (PM2.5) that imposes adverse health effects, large uncertainty in radiative forcing, and poor visibility. Monoterpenes represent about 15% of the annual emissions of biogenic volatile organic compounds …

Studies of the interaction of biogenic volatile organic compounds and NOx in forest environments
… by the chemistry between biogenic volatile organic compounds and NO<sub>x</sub> (NO + NO<sub>2</sub>), and therefore, a greater understanding of NO<sub>x</sub> + BVOC chemistry along with their sources and sinks is needed. One large uncertainty in understanding NO<sub>x</sub> + BVOC …

Fundamental Studies of Reactions between NO3 Radicals and Organic Surfaces
… with well-organized, highly characterized, organic thin films. The surface reactions were monitored in situ with reflection-absorption infrared spectroscopy (RAIRS). The oxidation states of surface-bound molecules were identified with X-ray photoelectron spectroscopy (XPS). Consumption of …

Elucidating the chemistry of particulate and chlorinated nitrates in the troposphere through method development, and chamber and field studies
… The potential loss of ClNO2 by uptake on inorganic and secondary organic aerosol (SOA) was investigated in a newly constructed smog chamber. Uptake probabilities (γ) were determined by box modeling constrained to measured ClNO2 mixing ratios and SMPS derived aerosol surface area. An upper …

Ultrahigh Vacuum Studies of the Reaction Kinetics and Mechanisms of Nitrate Radical with Model Organic Surfaces
… a key nighttime atmospheric oxidant, and organic particles will enable scientists to predict the fate and lifetime of the particles in the atmosphere. In an effort to acquire knowledge of interfacial reactions of nitrate radical with organics, model surfaces are created by the spontaneous …

Einfluss von Vitamin C und Atorvastatin auf die hämodynamische Wirkung von Isosorbid-5-mononitrat
In einer früheren Studie zur Untersuchung der dosisabhängigen Wirkung einer Einzeldosis von Isossorbid-5-mononitrat (IS-5-MN) wurde beobachtet, dass bei einer Dosissteigerung von 40 auf 80 mg trotz Verdopplung der Plasmakonzentration keine Wirkungszunahme auf-trat. Vor diesem Hintergrund wurde eine …
