2. 1. Carbon Nitride : Characterization and Protein Interactions

   Author : Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. READ MORE

4. 2. Free-Vehicle Benthic Lander Technology for the Study of Biogeochemical Processes in Marine Sediments

   Author : Anders Tengberg; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; marine sediments; benthic fluxes; incubations; chambers; in-situ; benthic landers; autonomous vehicles; lander technology; hydrodynamics; calibration; experimental design; Partial Least Squares PLS ; sensors; fugacity; oxygen; carbon; nitrogen; phosphorus; silica; dissolved organic carbon DOC ; total carbonate; recycling; burial; lander technology;

   Abstract : Various sediment sampling and incubation techniques were used to characterize benthic biogeochemical processes important for an improved understanding of the oceanic carbon cycle. Recent flux data from the Arctic Siberian shelf are revealing differences (often by a factor of ten) between areas affected by the big Russian river outlets (high fluxes) and areas with low influence from land (low fluxes).

5. 3. Carbon Fibres from Kraft Lignin

   Author : Ida Norberg; Monica Ek; Elisabeth Sjöholm; Göran Gellerstedt; Falk Liebner; KTH; []
   Keywords : ;

   Abstract : Kraft lignin has a high potential for use in more valuable applications than its current use as fuel in pulp mills and integrated pulp and paper mills. The possibility of using kraft lignin, a green material with a carbon content of more than 60 %, for the manufacturing of carbon fibres was investigated in this thesis. READ MORE

6. 4. Adding Utility to Carbon Materials: Introducing Dopants Using Highly Soluble Metal Salts and Functionalizing Surfaces via Bromomethylation

   Author : Samuel Joseph Fretz; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon materials; fuel cells; Li-S batteries; surface functionalization; doping;

   Abstract : Carbon-based materials have received intense research interest over the past few decades due to their unique  combination of properties including porosity, non-toxicity, chemical inertness, low density, and electrical conductivity, which has allowed them to find a wide array of applications including supercapacitors, batteries, CO2 capture, fuel cells, and catalysis. To expand their utility, a variety of techniques have been developed to enhance their reactivity and functionality. READ MORE

7. 5. Method development for [11C]carbon monoxide radiochemistry

   Author : Mélodie Ferrat; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Positron emission tomography (PET) is a non-invasive molecular imaging technique that has found extensive utility in biomedical research and in drug development. A fundamental pre-requisite for PET is the tracer, which is a biologically relevant molecule, labeled with a short-lived radionuclide. READ MORE
