1. 21. Recombination losses in organic solar cells : Study of recombination losses in organic solar cells by light intensity-dependent measurements

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Sebastian Lind; [2018]
   Keywords : Organic solar cells; recombination losses;

   Abstract : Easy manufacturing, light weight and inexpensive materials are the key qualities of organic solar cells that makes them a highly researched area. To make organic solar cells adequate for the market, the efficiency of power conversion has to increase further, and the lifetime of organic solar cells has to improve. READ MORE

3. 22. Impact of plant ecotype on Bacillus-mediated growth promotion : extending beyond the standard model plant

   University essay from SLU/Dept. Of Plant Biology

   Author : Staffan Matzén; [2018]
   Keywords : bacillus; growth promotion; root exudates; volatiles;

   Abstract : This study investigated how bacterial treatment modulates plant growth. Bacillus amyloliquefaciens UCMB5113 was used for treatment of several different natural accessions (ecotypes) as well as mutants of Arabidopsis thaliana. Treatment effect on plant root architecture was studied in particular. READ MORE

4. 23. Modeling of ozone and nitrogen oxides pollutions in urban air environments

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Henrik Reimer; [2018]
   Keywords : Ozone; Nitrogen oxides; NOx; Hydrocarbons; VOC; Urban environment; Model; Pollutions; Physics and Astronomy;

   Abstract : As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. READ MORE

5. 24. Placing VOC Sensors forAssessing Air Quality : A CFD Study of Indoor VOC Distribution

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Sara Högdahl; [2018]
   Keywords : ;

   Abstract : The Swedish Obligatory Ventilation Control (OVK) was established to ensure that ventilation systemsare clean and work according to design. The control system of today is however not perfect, and thereare many aspects of OVK which could be approached differently for improved efficiency and occupanthealth. READ MORE

6. 25. Identification of volatile organic compounds (VOC) and organophosphate flame retardants (OPFR) in building materials

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Daniel Duberg; [2017]
   Keywords : ;

   Abstract : Humans today spend most of their time in various indoor settings such as housing, schools and workplaces. The quality of the indoor environment is therefore of great significance for our wellbeing. However, it has been suggested that the indoor environment contains over 6000 organic compounds, such as various volatile organic compounds (VOC). READ MORE
