1. 6. Titania supported vanadium oxide catalysts in the NH3-SCR reaction: Effect of vanadium loading, promoters and aging

   Författare :Alexander Nellessen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nb; aging; Ce; infrared spectroscopy; VOx; NH3-SCR; vanadium oxide;

   Sammanfattning : Emissions of nitrogen oxides (NOx) from combustion processes in mobile sources attract significant attention due to their role as a major source of atmospheric contamination, along with health risks and environmental issues. Since combustion processes in heavy-duty vehicles are expected to be used for a foreseeable future, many efforts have been invested in a suitable deNOx technology. LÄS MER

3. 7. Tailormade Surfaces for Extended CE Applications

   Författare :Sara Ullsten; Karin Markides; Staffan Folestad; Gerhardus J de Jong; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; capillary electrophoresis; mass spectrometry; surface properties; coatings; polymers; liposomes; proteins; drugs; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : The combination of capillary electrophoresis (CE) and mass spectrometry (MS) constitutes a powerful microanalytical system in the fields of biology, medicine and chemistry. This thesis describes the development of three novel capillary coatings and demonstrates how these extend the utility of CE as a high-efficiency separation technique in protein analysis and biopharmaceutical drug screening.

4. 8. An Assessment of the Potential for Bio-based Land Uses on Urban Brownfields

   Författare :Shaswati Chowdhury; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban Greenspaces UGSs ; Brownfields; Gentle Remediation Options GROs ; Bio-based CE; Bio-based land use; Circular Economy CE ;

   Sammanfattning : Circular Economy (CE) is expected to accelerate the emerging shift in resource consumption from finite to renewable, and plants are key in enabling the switch as industries would opt more and more for resources with a bio-based origin. Cities have an important role in the process not only as the main consumers of the resources but also because vegetation provides numerous tangible and intangible ecosystem services essential for the wellbeing of urban dwellers.

5. 9. Orienting West Mexico: The Mesoamerican World System 200-1200 CE

   Författare :Peter F. Jimenez Betts; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Mesoamerica; Archaeology; World-Systems theory; World-Systems analysis; Nested Networks; West Mexico; Central Mexico; Early Classic; Epiclassic; Early Postclassic;

   Sammanfattning : As world-systems theory came to the fore in archaeology during the 1980s and 1990s, it became evident that the analysis of pre-capitalist core/periphery relations required modifications of this theory for its further use in the discipline. As a result, the comparative approach for world-systems analysis (Chase-Dunn and Hall 1997) discerned four interaction networks that defined pre-capitalist world-systems. LÄS MER

7. 10. Mass spectrometry based analysis of drugs, neurotransmitters and lipids in invertebrate model systems

   Författare :Nhu TN Phan; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CE-MS; Imaging mass spectrometry; Lipids; Neurotransmitters; Drug; Drosophila; C. elegans;

   Sammanfattning : Mass spectrometry (MS) is one of the most universal analytical techniques due to its label-free detection principle and high chemical specificity, high selectivity, and sensitivity. MS is diverse with many different types of systems to meet different analytical demands from various research areas. LÄS MER
