Structural and Functional Studies of Membrane Proteins For Future Development of Antimicrobial Drugs
(2019-01-10)Antibiotic resistance is a world-wide occurring problem which threatens human health. Without development of any new and effective antibiotics, the rapid growth of antibiotic-resistant bacterial infections could put society ... -
Isotope labeling of proteins for spectroscopic studies
(2018-11-15)Protein structural dynamics have been closely tied to the molecular mechanisms controlling for example enzyme activities. In my work, I have mainly studied the bacteriophytochrome from Deinococcus radiodurans. Phytochromes ... -
Structural Insight into the Bacterial Sialic Acid Catabolic Pathway
(2018-11-02)A genetically diverse community of commensal and pathogenic bacteria thrive in the digestive system and urogenital tracts of animals. Many of these bacteria forage sialic acid from mucosal cell surfaces. Bacteria have ... -
Biophotonics Targeting Pharmaceutical Challenges
(2018-08-23)The study of the interaction between light and biological matter, called biophotonics, contributes to our understanding of biological systems - from subcellular compartments up to the human organ system. Herein, light is ... -
Interaction of Natural Organic Matter molecules with TiO2 nanoparticles: An Experimental Adsorption and Aggregation study
(2018-08-16)Mechanisms by which synthetic nanoparticles are released into natural environments and the potential impact of nanoparticles on living organisms have been discussed frequently over the past decade. Interactions of nanoparticles ... -
Structural Features of Bacteriophytochromes. Photoactivated Proteins studied by Serial Femtosecond Crystallography
(2018-03-22)The key to life on earth is sunlight, which reaches the planet as an energy source. Nature has evolved different types of photoreceptor proteins to detect optimal light conditions for biochemical processes. A type of red ... -
Selectivity in the chlorate process: Hydrogen evolution and hypochlorite reduction on deposited chromium oxide/hydroxide
(2018-02-22)Abstract Production of chlorate is dependent of using sodium dichromate as a component in the electrolyte. Dichromate provides selectivity by forming a Cr(III) oxide-like film on the cathodes. Without dichromate, unwanted ... -
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 ... -
Alkali Metals and Tar in Biomass Thermochemical Conversion: Development and Application of Online Measurement Techniques
(2018-02-08)Biomass is a renewable resource that can substitute the fossil-based products we depend on today. However, the conversion techniques require further improvement in order to be competitive with the traditional industry. One ... -
A Soot Transformation Study: Interactions Between Soot, Sulfuric Acid and Secondary Organic Aerosol (SOA)
(2018-01-19)Atmospheric black carbon (BC), generally called soot, is the most important aerosol component that warms the Earth’s climate significantly, and reducing atmospheric soot level has been proposed as a strategy for near-term ... -
Atmospheric oxidation: Formation and aging of biogenic and traffic-related secondary aerosols
(2018-01-11)Atmospheric aerosol particles affect the quality of life by influencing climate and by being a significant component of air pollution. Once a particle is released into or formed in the atmosphere, several processes begin ... -
Development of Electrochemical Biosensors for Neurochemical Applications
(2018-01-04)The brain consists of billions of cells, including nerve cells, which have the ability of transforming an incoming electrical signal in to a chemical output by the release of neurotransmitters through a process called ... -
Signal Transduction in Photoreceptor Proteins
(2017-10-26)The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals ... -
Peroxiredoxins in Redox Signaling and Aging
(2017-10-23)Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not ... -
Creating Optical Activity: Total Spontaneous Resolution and Viedma Ripening
(2017-10-18)The creation of optical activity has been considered as something impossible even though reports of such creation via total spontaneous resolution since the 1940´s have been published. More recently Viedma ripening have ... -
The solution conformations of macrocycles. Applications in the exploration of weak interactions and in drug development
(2017-09-26)Understanding the solution conformation and dynamics of molecules with biological relevance, as well as the impact of their conformation stabilizing weak interactions, is for example important for drug design. Macrocycles ... -
Microbial communities in anammox and nitrifying biofilms
(2017-09-19)Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. ... -
Airborne particulate matter in a Sub-Saharan Africa city: Nairobi, Kenya, and at an Equatorial high altitude site: Mount Kenya
(2017-09-13)In Sub-Saharan Africa (SSA), air quality is gravely understudied despite the existing influential factors such a rapid urbanization and population growth that negatively affect the environment. Majority of urban areas in ... -
