3. 7. Biodegradable gelatin microcarriers in tissue engineering : In vitro studies on cartilage and bone

   Författare :Sofia Pettersson; Gunnar Kratz; Pentti Tengvall; Jonas Wetterö; Julie Gold; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Tissue engineering is a multidisciplinary field that combines cells, biomaterial scaffolds and environmental factors to achieve functional tissue repair. This thesis focuses on the use of macroporous gelatin microcarriers as scaffolds in tissue engineering applications, with a special focus on cartilage and bone formation by human adult cells in vitro.

4. 8. Forest based biorefinery supply chains - Identification and evaluation of economic, CO2, and resource efficiency

   Författare :Jonas Zetterholm; Elisabeth Wetterlund; Joakim Lundgren; Karin Pettersson; Johanna Mossberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Sammanfattning : Biorefineries for production of fuels, chemicals, or materials, can bean important contribution to reach a fossil-free economy. Large-scaleforest-based biorefineries are not yet cost competitive with their fossil counterparts and it is important to identify biorefinery supply chain configurations with good economic, CO2, and biomass performance if biorefineries are to be a viable alternative to the fossil refineries.

5. 9. X-ray scattering and spectroscopy of supercooled water and ice

   Författare :Jonas A. Sellberg; Anders Nilsson; Lars G. M. Pettersson; Thomas Loerting; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supercooled water; ice; x-ray scattering; x-ray spectroscopy; free-electron laser; kemisk fysik; Chemical Physics;

   Sammanfattning : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. LÄS MER

7. 10. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications

   Författare :Niklas Forsgard; Jean Pettersson; Marit Andersson; Jonas Bergquist; Walter Lund; Uppsala universitet; []
   Nyckelord :Analytical chemistry; Speciation analysis; Atomic emission spectrometry AES ; Mass spectrometry MS ; Inductively coupled plasma ICP ; Liquid Chromatography LC ; on-line sample pre-treatment; Organic phosphour; Siderophores; Slurry nebulization; matrix effects; Analytisk kemi;

   Sammanfattning : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.
