2. 1. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping

   Author : Fayas Malik Kanchiralla; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impact; life cycle costing; battery electric; fuel cells; electro-fuel; technical feasibility; economic impact; hydrogen; life cycle assessment; carbon capture; marine fuel; engines; ammonia; carbon abatement cost; shipping; methanol;

   Abstract : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. READ MORE

4. 2. Using affordable materials from metallurgical industries in Oxygen Carrier Aided Combustion and Chemical-Looping Combustion

   Author : Felicia Eliasson Störner; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen carriers; Ash interactions; Potassium interactions; Chemical-Looping Combustion; Oxygen Carrier Aided Combustion;

   Abstract : Oxygen carriers are solid oxides of transition metals that can be used to convert fuel in the absence of gaseous oxygen in a process called Chemical-Looping Combustion (CLC). The use of oxygen carriers makes it possible to produce undiluted CO2 without expensive gas separation. READ MORE

5. 3. Electronic Structure and Transport in Nanofabricated Low-Dimensional Semiconductor Systems : A theoretical study

   Author : Chuan-Kui Wang; Hongqi Xu; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Systematic studies of the transport properties in one type of low-dimensional semiconductor nanostructures, in which the motion of carriers is governed by quantum mechanics, are presented in this thesis. In addition, the electronic states in lowdimensional systems fabricated from GaAs / Al?Ga1-?As heterostructures have been investigated by using both transport methods and the static calculations.

6. 4. Water treatment using cryogel-based adsorbents - Targeting environmental pollutants at low concentrations

   Author : Linda Önnby; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; cryogels; nanoparticles; arsenic; cadmium; water treatment; composites;

   Abstract : The lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. READ MORE

7. 5. Disease activity, function and costs in early rheumatoid arthritis

   Author : Eva Hallert; Thomas Skogh; Jan Persson; Ronald van Vollenhoven; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antirheumatic agents; Rheumatoid arthritis; Cost of illness; Health care costs; Joints physiopathology; Sex factors; Rheumatology; Reumatologi;

   Abstract : Rheumatoid arthritis (RA) is a major cause of progressive joint damage and disability, and is associated with decline in quality of life, reduced ability to work and increased health care utilisation. The economic consequences of the disease are substantial for the individuals and their families and for the society as a whole. READ MORE
