Effect of Microwaves on Microtubule Structure and Function probed by Light and X-ray Scattering
(2018-02-15)We are constantly exposed to radiation in some form or another from our environment. High frequency electromagnetic radiation, including ultraviolet light and X-rays, cause damage to living organisms due to ionization ... -
The Effect of Site-Specific Mutations on hIAPP Fibril Polymorphism: A Cryo-EM Study Towards Potential Inhibitors
(2024-01-25)The development of amyloid deposits in tissues, as a consequence of the self-assembly of misfolded proteins, is a critical pathological feature in a range of diseases, including neurodegenerative disorders and metabolic ... -
Electrocatalytic properties of Ni hydroxides with Zn or Co in the Ni matrix
(2014-01-17)The majority of the work in this thesis has been made with the improvement of the systems for electrochemical co-generation of chemicals and electricity in mind. This is an appealing but challenging way of producing chemicals ... -
Electrochemical and microscopic analysis of chemical signalling in biological systems
(2019-10-01)Cellular communication is a prerequisite in multicellular organisms in order to survive. Many times, this communication occurs through the highly controlled and regulated release of chemical signals through a process known ... -
Electromagnetic Field Induced Out-of-Equilibrium Structural Dynamics in Protein Crystals: From Picoseconds to Milliseconds
(2022-02-04)Light-induced interactions in biomolecules are strongly varying over different model systems. Most amino acids and proteins absorb ultraviolet light, but only a few with specialised chromophores or fluorophores, are able ... -
Emerging roles and functional mechanisms of dynein light chain DYNLRB1 and DYNLRB2
(2024-10-28)Dyneins are a class of molecular ATPase motors that generate force and movement on microtubules in a wealth of biological processes, including organelle distribution, cell division, ciliary beating, and flagella motility, ... -
Energy efficiency in the sodium chlorate process: From electrocatalysis to pilot plant investigations
(2017-04-24)Sodium chlorate is an important industrial chemical produced through an electrochemical manufacturing process. The global production rate is 3.6 million tons annually and consumes approximately 20 TWh of electrical power. ... -
Epoxides as Contact Allergens - Formation, Sensitising Potency and Structure-Activity Relationships
(2013-10-31)Chemicals in our environment with which we have repeated skin contact can cause skin sensitisation (contact allergy). To trigger an immune response a compound (hapten) must be able to penetrate the skin, where it needs to ... -
Escape from the cage: Ultrafast structural dynamics of photodissociation reactions observed with X-ray solution scattering
The environment of a molecule is known to greatly impact the course of a reaction. Such an environment can, for instance, be the solvent in a solution phase reaction or the amino acid residues surrounding a chromophore in ... -
Excited state dynamics in the strong coupling regime
(2022-02-24)Strong exciton-photon coupling exhibits the possibility to modify photophysical and photochemical properties of organic molecules without changing their structure. This is due to the formation of hybrid light-matter states, ... -
Exciton coupling and energy transfer in perylene-based systems
(2022-01-07)Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and ... -
Experimental Protein Dynamics and its Role in Predicting Protein Function
(2022-05-04)By studying proteins we learn about the processes that control life, such as important procedures in the body, diseases and eventually find more targeted cures for many diseases. Proteins are constantly being built up ... -
Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery
(2014-03-18)The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. ... -
Formation and Distribution of Marine Biogenic Halocarbons with Emphasis on Polar Regions
(2012-10-19)It is well-established that marine micro- and macroalgae form volatile halogenated compounds (halocarbons). Production occurs throughout the world ocean with strong regional sources in coastal areas. In the atmosphere, ... -
Formation and Transformation of Atmospheric Brown Carbon (BrC)
(2022-11-23)Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked ... -
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+ ... -
Formation, ageing and thermal properties of secondary organic aerosol
(2013-02-07)In order to properly represent and predict the effects of aerosol in climate systems, an accurate description of their formation and properties is needed. This thesis describes work done to increase the knowledge of processes ... -
FoxF genes in development and disease
(2014-05-08)Forkhead transcription factors of the FoxF group are important during embryonic de-velopment, and mutation of either of the members, Foxf1 and Foxf2, has fatal conse-quences. In this thesis, I present our recent findings ... -
