The Interaction of Nitrogen Monoxide with Pyrolysed Polyacrylonitrile
… has been to investigate the interaction between nitrogen monoxide (NO) and pyrolysed acrylonitrile copolymer (PAN.P). This interaction has been established and studied in some detail over the temperature range 250 to 700°c. At the same time the feasibility of using PAN.P based catalysts for the …

Catalytic Reactions of Highly Conjugated Polymers: the Removal of Nitrogen Monoxide from Gas Streams using Pyrolysed Polyacrylonitrile
… as a heterogeneous catalyst for the removal of nitrogen monoxide from motor vehicle exhaust gas. Previous work had shown that the polymer was capable of removing nitro-gen monoxide from gas streams and it was intended to optimise the activity of the polymer and to investigate the nature of the …

Die Bedeutung der NO-Synthasen im murinen Modell der septischen Hämodynamik
… An important mediator for these two phenomena is nitrogen monoxide. It was the object of the present dissertation to examine the nitrogen-oxide-mediated effects on septic haemodynamics in a murine CLP model and to clarify the significance attributable to the respective NO synthases in this …

Acyloxy Nitroso Compounds as HNO Donors and Their Reactions with Thiol and Heme Containing Proteins
Nitroxyl (HNO), a nitrogen monoxide with distinct chemistry and biology, has gained interest as a potential treatment of congestive heart failure through the ability of the HNO donor, Angeli's salt (AS), to evoke positive inotropic effects in canine cardiac muscle. The release of nitrite during …

Laser Remote Sensing for Environmental Monitoring
… of two serious pollutants, atomic mercury and nitrogen monoxide, have been performed in the same Chinese city. Further, DIAL is also proved to be valid for remote gas analysis in multiple-scattering media. Fluorescence LIDAR can recognize the molecules contained in a remote target, through …

Turbulent Exchange of Ozone and Nitrogen Oxides between an Amazonian Rain Forest and the Atmosphere
… the deposition of constituents like ozone and nitrogen oxides, which are of high relevance for tropospheric chemistry. To asses the effect of land use change on tropospheric chemistry, a good knowledge of the exchange of those trace gases between the primary rain forest ecosystem and the …

Fluxes of the NO-O3-NO2 triad above a spruce forest canopy in south-eastern Germany
Nitrogen monoxide (NO) and nitrogen dioxide (NO2) (denoted together as NOx) are important compounds for the regulation of the tropospheric photochemical oxidant ozone (O3). Although they account for less than one millionth of the total constituents of the atmosphere, they play an important role in …

Studies of urban air quality using electrochemical based sensor instruments
Poor air quality has been projected to be the world’s top cause of environmental premature mortality by 2050 surpassing poor sanitation and dirty water (IGBP / IGAC press release, 2012 ). One of the major challenges of air quality management is how to adequately quantify both the spatial and …

Electron Transfer and Other Reactions Using Atomic Metal Anions
The atomic metal anions Rb-, Cs-, Cu-, Ag- and Fe- have been generated in the gas phase and reacted with various neutral reactants in a triple quadrupole mass spectrometer. The metal anions were formed via electrospray ionization of the metal-oxalate solutions and form in gas phase between the …
