2. 1. Molecular Beam Studies of Interactions Between Ice Surfaces and Atmospherically Relevant Molecules

   Author : Liza Romero Lejonthun; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular beam; surface; surface scattering; collision; water ice; ice; chlorine; nitrogen oxides; nitrogen monoxide; nitrogen dioxide; dinitrogen tetroxide; dinitrogen pentoxide; nitric acid; helium; graphite;

   Abstract : The discovery of the ozone hole over Antarctica in 1985 was one of the environmental issues that attracted most attention worldwide in the end of the last century. The cause of the ozone hole formation was proven to be coupled to the emission of chlorofluorocarbons (CFCs). READ MORE

4. 2. Chemical Interactions between Potassium, Nitrogen, Sulfur and Carbon Monoxide in Suspension-Fired Systems

   Author : Thomas Allgurén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sulfation; combustion; CO-oxidation; modelling; oxy-fuel; NO-formation; experiments; alkali;

   Abstract : Drastic cuts in global CO2 emissions are needed to mitigate global warming and limit the average temperature increase to well below 2ºC. The power generation sector is largely based on fossil fuels and generates a significant share of the global CO2 emissions. READ MORE

5. 3. Exhaled nitrogen oxides and carbon monoxide in asthma and cystic fibrosis : markers of inflammation?

   Author : Wilhelm Zetterquist; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Exhaled markers of airway inflammation have attracted much interest as potential tools for monitoring the bronchial inflammation of respiratory disease. Exhaled nitric oxide (NO), its metabolites nitrite and nitrate in breath condensate (EBC), and exhaled carbon monoxide (CO), have been suggested for this purpose. READ MORE

6. 4. Diurnal variation of stratospheric short-lived species

   Author : Maryam Khosravi; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chlorine monoxide; short-lived species; Arctic ClO; diurnal variation; tropical middle stratosphere; Arctic stratosphere;

   Abstract : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature activity; CO oxidation; operando spectroscopy; water promotion; active catalyst support; nitrogen oxide inhibition;

   Abstract : Catalytic oxidation of carbon monoxide (CO) is one of the most studied reactions that still needs to be improved because of its practical use in the chemical industry including feedstock purification and applications such as emission control, in-door air cleaning, improvement of fuel cell efficiency, etc. Concerning CO emissions, the transportation sector is a large contributor.
