2. 1. Exploring the Use of Terpenes as Renewable Polymer Feedstock

   Author : Arne Stamm; Per-Olof Syrén; Nico Bruns; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-based polymers; terpenes; α-pinene; sobrerol methacrylate SobMA ; verbanone lactone VaL ; 1- 1 -hydroxyethyl -3- 2 -hydroxyethyl -2; 2- dimethylcyclobutane HHDC .; Kemi; Chemistry;

   Abstract : Rising environmental awareness and responsibility has increased the demand for novel,  bio-based  sustainable  materials.  Therefore,  there  is  an  extensive  need  to research  and  develop  closed-loop  materials  from  novel  feedstocks  that  can  be generated  using  benign,  environmentally  friendly  synthetic  routes.

   Abstract : The chemical elicitor methyl jasmonate (MeJA) could replace insecticides in Europe and Asia for protection of young conifers against the pine weevil (Hylobius abietis). This thesis mainly focuses on the effects of MeJA treatment on chemical defenses of conifers from seedling batches with documented field resistance. READ MORE

5. 3. Heterogeneously Catalyzed Valorization of Monoterpenes to High Value-Added Chemicals

   Author : Mikhail Golets; Jyri-Pekka Mikkola; Evgenii Rebrov; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalysis; terpenes; alpha-pinene;

   Abstract : A potential industrial process is profitable only if it is successfully implemented by the continuously developing chemical industry. Throughout last decades heterogeneous catalysis has opened doors to the creation of various know-how products which previously were considered unfeasible. READ MORE

6. 4. Insights into key processes governing atmospheric aerosol loadings and their interactions with clouds

   Author : Emelie Linnéa Graham; Ilona Riipinen; Claudia Mohr; Paul Zieger; Annica M. L. Ekman; Marianne Glasius; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Aerosol particles are ubiquitous in the atmosphere and an essential part of the atmospheric radiation balance regulating the Earth’s temperature. Aerosol-cloud interaction still remains the largest single uncertainty in future climate projections. In addition, aerosols are also responsible for air pollution, causing severe health effects.

7. 5. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols

   Author : Åsa M. Jonsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tropospheric chemistry; monoterpenes; ozonolysis; secondary organic aerosol SOA ; G-FROST; AIDA; humidity; temperature; hydroxyl radicals; volatility; pinonaldehyde; climate and health;

   Abstract : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. READ MORE
