1. 11. Nanostructured Transition Metal Oxides in Cleantech Application : Gas Sensors, Photocatalysis, Self-cleaning Surfaces Based on TiO2, WO3 and NiO

   Författare :Zareh Topalian; Lars Österlund; Andrew Mills; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas sensing; Self-cleaning; photo-fixation; photocatalysis; TiO2; WO3; NiO; Surface engineering; Ytbehandlingsteknik; Functional materials; Funktionella material; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : This thesis focuses on the application of nanocrystalline transition metal oxide TiO2, WO3 and NiO thin films in new “green” building technologies. Specifically, their physicochemical properties in photocatalytic, self-cleaning and gas sensing applications are studied. LÄS MER

3. 12. Nasal reactions and the school environment : Nasal patency and lavage biomarkers in relation to ventilation, cleaning and some indoor air pollutants

   Författare :Robert Wålinder; Uppsala universitet; []
   Nyckelord :Medical sciences; acoustic rhinometry; enviromnental illness; eosinophil cationic protein ECP ; formaldehyde; lysozyme; mold; nasallavage; nasal obstruction; N02; rhinitis; school; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

   Sammanfattning : In Sweden, 2 million persons are exposed to the school environment, and there has been reports on insufficient cleaning, and inadequate ventilation. The nasal mucosa is more easy to study than the lower airways, and rhinitis is common and possibly related to asthma. LÄS MER

4. 13. Non-ionic block copolymers and proteins at the air-water interface

   Författare :Brita Rippner Blomqvist; Per M. Claesson; Cosima Stubenrauch; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : The behavior of block copolymer and protein films at interfaces is of central importance to their function in many application areas. Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers function e.g. LÄS MER

5. 14. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes  in power plants

   Författare :Zhafira Darmastuti; Anita Lloyd Lloyd Spetz; Lars Ojamäe; Mike Andersson; Niclas Lindqvist; Mikael Larsson; Jaco Visser; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.

7. 15. Exposing the Exposures : Assessing occupational aerosol exposures and their possible health and toxicological effects

   Författare :Karin Lovén; NanoLund: Centre for Nanoscience; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerosol; Occupational exposure; Spray; Engineered nanomaterial; Air-liquid interface; Toxicology;

   Sammanfattning : According to the Global Burden of Disease study, occupational exposures to particulates, gases and fumes were responsible for 0.36 million deaths and 8.8 million disability-adjusted life years globally in 2015. LÄS MER
