2. 6. Carbon Credits: Origins, Effectiveness & Future

   Author : Linn Takeuchi Waldegren; Miljö- och energisystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additionality; carbon credits; Clean Development Mechanism CDM ; effectiveness; emissions reductions;

   Abstract : Carbon credits are used as an instrument for climate change mitigation. Each credit represents a reduction in greenhouse gas emissions (GHGs) equivalent of 1 ton of carbon dioxide. READ MORE

4. 7. Development of Protein-Functionalized Magnetic Iron Oxide Nanoparticles: Potential Application in Water Treatment

   Author : Chuka Okoli; Gunaratna Kuttuva Rajarao; M. Arturo López-Quintela; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The treatment of water to make it safe for human consumption is a problem of immense concern, both in developing and developed countries. However, the production of clean water with chemicals as coagulants has several drawbacks associated with cost, health risks and complexity in sludge management. READ MORE

5. 8. Development of GC-HRMS procedures for determination of naturally occuring polar compounds in various environmental applications

   Author : Bodil Widell; Dag Broman; Caroline Leck; Joan Grimalt; Stockholms universitet; []
   Keywords : GC-HRMS; steroid hormones; amino acids; perch; size-resolved aerosol; Arctic; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : The overall objectives of this dissertation were to gain further understanding of the two following environmentally significant issues: (i) Determination of natural steroid hormones in blood plasma from perch (Perca fluviatilis) during a reproductive cycle and to evaluate the possibility of using the steroid composition as a biomarker for early signs of endocrine disruptive effects. (ii) Determination of dissolved free amino acids in size resolved airborne particles collected over the Arctic pack ice area (>80°N) in summer and to study their overall relationship with the ocean surface microlayer as a potential source.

6. 9. Fundamental Aspects of Lignin Carbohydrate Complexes (LCC) : Mechanisms, Recalcitrance and Material concepts

   Author : Nicola Giummarella; Martin Lawoko; Gunnar Henriksson; Arthur J. Ragauskas; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lignin Carbohydrates Complexes; Phenyl Glycosides; Benzyl Ethers; Benzyl and γ-esters; Universal Mild Quantitative fractionation; LCC mechanism formation; Extracellular lignin; Dehydogenation polymer; Autohydrolysis; Recalcitrance; Acetylation role; HSQC; HMBC; HSQC-TOCSY; 13C; 31P NMR; Thioacidolysis-GC; SEC; Green; Biomimetic; One-pot-lignin functionalization; Lignin platform material.; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Covalent bonds between lignin and carbohydrates, forming a matrix referred to as lignin carbohydrate complexes (LCC), remain one of the most controversial topics in wood chemistry. A key issue is whether they are formed during chemical and mechanical pretreatments of the compact wood structure or actually present in wood prior to isolation. READ MORE

7. 10. Design and synthesis of rhodium and iridium bis-η2 diolefin catalysts: : Applications in C–C bond formation and asymmetric catalysis

   Author : Michaela Melcher; Centrum för analys och syntes; []
   Keywords : catalysis; transition metal; ligand design; enantioselectivity; cycloadditions;

   Abstract : This thesis deals with the design and synthesis of rhodium and iridium bis-η2 diolefin catalysts and their applications in C–C bond formation and asymmetric catalysis.More specifically, the second chapter describes the development of inter- and intramolecular (5+2) cycloadditions catalyzed by cationic iridium(I) complexes that lead to the formation of seven-membered rings in a single step.
