2. 1. Measuring Elemental Carbon in Occupational Environments

   Author : Anna Wallén; Hans-Christen Hansson; Göran Lidén; Karine Elihn; Thomas Kuhlbusch; Stockholms universitet; []
   Keywords : Diesel Exhaust Particles; Thermo-Optical Analysis; Black Carbon; Pyrolytic Carbon; Wood Smoke Particles; Water Soluble Organic Compounds; Asphalt Paving Work; Bio Fuels; Subway Aerosol; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Carbonaceous aerosol particles from combustion, such as diesel exhaust particles (DEP), harm human health and affect the Earth’s radiative system.Elemental carbon (EC) has been proposed to be used as a marker of DEP. READ MORE

4. 2. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

   Author : Hans Fredriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

   Abstract : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

   Abstract : Bioenergy with Carbon Capture and Storage represents a crucial technology that enables an energy production with negative carbon emissions, which is needed to achieve global climate goals. Appropriated management of biodegradable waste, including biodegradable lignocellulosic waste, sewage sludge, organic fraction of municipal solid waste, can make this contribution. READ MORE

6. 4. Development and Evaluation of Methods in Source Apportionment of the Carbonaceous Aerosol

   Author : Johan Martinsson; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbonaceous aerosol; organic aerosol; aerosol particles; source apportionment; air pollution;

   Abstract : Carbonaceous aerosols are known to affect human health negatively and to affect the climate of Earth. As specific types of aerosols originate from specific sources, it is important to know the amount of aerosols emitted from each source. Aerosol source apportionment is an important tool in mitigating air pollution and improving air quality. READ MORE

7. 5. Optimal pacing with and implantable pO2 sensor

   Author : Nils Holmström; KTH; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : A goal in modern pacemaker technology is to adapt the timing of stimulation to the metabolic demand and to optimize the hemodynamics of the diseased heart. Because the plasma concentration of mixed venous oxygen is a good indicator of workload and circulation, we developed an implantable coulometric blood oxygen sensor to improve the rate adaptation.
