1. 1. Local structure and composition : in additively manufactured bulk metallic glasses and composites

   Författare :Inga Katharina Goetz; Jochen M. Schneider; Björgvin Hjörvarsson; Ulf Jansson; Maria Teresa Pérez Prado; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; additive manufacturing; bulk metallic glasses; nanoscale clustering; convective flow; laser nitriding; laser powder bed fusion; metallic glass - ceramic composites; oxygen impurities; mechanical properties; magnetic properties; viscosity; Fysik; Physics;

   Sammanfattning : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. LÄS MER

3. 2. Image-based multi-omics data integration : Exploring whole-body PET/MRI, -omics data and body composition

   Författare :Robin Visvanathar; Håkan Ahlström; Joel Kullberg; Jan Eriksson; Katrine Riklund; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Body composition; Imiomics; genomics; metabolomics; MRI; PET; insulin sensitivity; T2D;

   Sammanfattning : Advanced body composition analysis with whole-body imaging could uncover novel associations between regional tissue composition and metabolic disease. Imiomics is an automated image analysis framework that enables large-scale integration of magnetic resonance imaging (MRI) data and orthogonal technologies such as metabolomics and genomics for the detailed study of body composition.

4. 3. Adsorption of dissolved organic matter in aquatic ecosystems : Effects on composition and reactivity

   Författare :Marloes M. Groeneveld; Lars Tranvik; Dolly Kothawala; Suzanne Tank; Uppsala universitet; []
   Nyckelord :dissolved organic matter; DOM; carbon; aquatic; adsorption; mineral particles; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

   Sammanfattning : Inland waters receive organic matter from terrestrial ecosystems and in situ production. In transit from land to the ocean, dissolved organic carbon (DOC) may be mineralised to inorganic forms (CO2 and CH4) by microbial degradation and photodegradation. LÄS MER

5. 4. The influence of solvent composition on crystal agglomeration of paracetamol

   Författare :Eva Ålander; KTH; []
   Nyckelord :paracetamol; solvent composition; agglomeration; image analysis; principal component analysis; agglomerate strength; interfacial energy;

   Sammanfattning : This thesis deals with the influence of solvent compositionon crystal agglomeration of paracetamol. Much work has beendone on characterisation of the crystalline product.Interfacial energies have also been determined for large singlegrown crystals. LÄS MER

7. 5. A Study of Parameters that Influence the Kinetics of the AOD Decarburisation Process

   Författare :Patrik Ternstedt; Anders Tilliander; Ville-Valteri Visuri; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; decarburization; steel; slags; composition; petrography; physical modeling; industrial plant trials; AOD; avkolning; stål; slagg; sammansättning; petrografi; fysikalisk modellering; industriella försök; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

   Sammanfattning : This thesis focuses on the AOD process, which is an important metallurgical reactor in stainless steel production. To be more specific, the thesis is limited to study the decarburisation step, which is the first of three process steps in the AOD converter. LÄS MER
