1. 1. Gas Chromatography Mass Spectrometry Analysis of Epoxides in Gas Phase Reactions

   University essay from KTH/Kemi

   Author : Stephanie Kylington; [2022]
   Keywords : organic peroxy radicals; unsaturated alkenes; TD-GCMS; Tenax® TA; internal standard; organiska peroxidradikaler; omättade alkener; TD-GCMS; Tenax® TA; intern standard;

   Abstract : En nyligen genomförd studie visade att reaktioner mellan vissa radikaler och omättade alkener är snabbare vid rumstemperatur än vad man tidigare har trott. Dessa reaktioner är viktiga för atmosfäriska oxidationscykler och följaktligen var syftet med detta masterprojekt att beräkna hastighetskonstanterna för dessa reaktioner mellan metyljodid och 1-jodidpentan med tetrametyletylen, isopren och limonen vid rumstemperatur genom att kvantifiera respektive epoxid; tetrametyloxiran, isoprenmonoxid och limonen 1,2 epoxid, som producerades.

3. 2. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alexandra Arnsteg; [2022]
   Keywords : BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

   Abstract : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

4. 3. Production and harvesting of volatile jet fuel precursors from Synechocystis sp. PCC 6803

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Johan Sjölander; [2019]
   Keywords : Jet fuel; isoprene; isobutene; cyanobacteria; solar fuel; photobioreactor; photosynthesis;

   Abstract : The world is currently faced with the enormous challenge of slowing down human triggered global warming. As the global energy demand increases, there is an urgent need for renewable and carbon-neutral fuel-sources. READ MORE

5. 4. Estimation of the potential BVOC emissions by the different tree species in Malmö

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Larissa Lisa Gesa Scholz; [2019]
   Keywords : BVOC emissions; isoprene; monoterpene; air quality; Malmö; Earth and Environmental Sciences;

   Abstract : BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. READ MORE

6. 5. Early season BVOC emission for young potted Norway spruce (Picea abies)

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Erica Jaakkola; [2019]
   Keywords : Physical Geography and Ecosystem analysis; BVOC; Norway spruce; PTR-TOFMS; photosynthesis; Earth and Environmental Sciences;

   Abstract : Biogenic volatile organic compounds (BVOC) are emitted naturally from the biosphere to the atmosphere and are a part of the global carbon emissions. BVOCs are contributing to around 5-10% of the total net carbon exchange to the atmosphere. READ MORE
