Alkali Uptake and Release from Oxygen Carriers in Chemical Looping Applications: Development and Application of Reactor Systems and Measurement Techniques
(2023-10-31)Chemical looping combustion (CLC) of biomass is a heat and power generation technology with minimal associated costs for carbon capture, potentially resulting in negative CO2 emissions. The CLC technology utilizes fluidized ... -
Bridging the past to the present: investigating species boundaries with herbarium specimens and next-generation-sequencing. A case study of circumpolar Silene sect. Physolychnis
(2023-10-30)During the recent decades, genetic information enclosed in herbarium collections have been partly revealed, largely due to the fast-moving high-throughput sequencing technologies. However, the genetic outcome from herbarium ... -
Morphological and chemical leaf traits of tropical montane tree species and their responses to warming
(2023-10-26)Leaf morphological and chemical traits of tropical trees vary along climate gradients, but it is currently unclear how they will respond to a rapidly warming climate and how this will vary among species. Considering this, ... -
MST3 and MST4: Critical Regulators of Liver Lipid Partitioning and Hepatocarcinogenesis
(2023-10-25)Non-alcoholic fatty liver disease (NAFLD) encompasses a disease spectrum ranging from hepatic steatosis to non-alcoholic steatohepatitis (NASH), fibrosis, and finally cirrhosis. With no approved pharmacological treatment, ... -
Novel Marine Ingredients for Aquaculture - Fish Nutrition, Physiology and Intestinal Health
(2023-10-24)Aquaculture is among the fastest growing food production sectors globally and supplies more fish to the growing human population than capture fisheries. One of the major challenges in salmonid aquaculture is to find ... -
Seaweeds as a future protein source: innovative cultivation methods for protein production
(2023-10-20)As the global population is projected to reach approximately 10 billion people by 2050, it is estimated that we will need to produce up to 60% more food compared to 2010. Although the current food production system contributes ... -
Formation of small molecules in space through the process of radiative association
(2023-10-16)This thesis is dedicated to calculating the reaction rate constants for the formation of molecules through radiative association (RA) under interstellar conditions. The molecules that have been studied are CH, AlCl, Na+ ... -
Implementation and development of serial synchrotron crystallography at MAX IV
(2023-10-11)Over the past decade, remarkable advancements in femtosecond X-ray free-electron lasers (XFELs) have brought about a profound transformation in structural biology. These XFELs have opened up exciting opportunities for ... -
Tomorrow is yesterday: early-life conditions shape ectotherm life histories
(2023-09-29)Life history theory seeks to explain the overwhelming diversity of resource allocation strategies in nature by exploring how evolutionary forces optimise survival and reproduction within an organism’s environment. Central ... -
Microcrystallization and structural studies of proteins by serial crystallography and x-ray scattering
(2023-09-20)Proteins are the most complex and versatile biomolecules known, with essential roles in all cellular and physiological processes. They constitute the main structural components of cells, catalyze most biochemical reactions, ... -
Phylogenetic Relationships, Biogeography and Species Delimitation: A case study on southern African Silene (Caryophyllaceae)
(2023-09-20)The primary aim of this thesis was to explore the phylogenetic relationships and historical biogeography of African members of the plant genus Silene (Caryophyllaceae), with special focus on the eight native southern African ... -
Survivors of the Sea: Investigating the genomics and survival strategies of the diatom Skeletonema marinoi
(2023-09-14)Diatoms are an ecologically important group of phytoplankton, responsible for around 20% of global primary production. One of the features contributing to their success is their ability to form resting stages, a response ... -
Advanced methods for the calibration of optical tweezers
(2023-09-08)Optiska pincetter har sedan Arthur Ashkin och hans kollegors uppfinning på 1980-talet möjliggjort noggrann manipulation av mikroskopiska partiklar. Denna teknik har haft betydande inverkan inom flera områden, inklusive ... -
