Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)
(2020-01-15)Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There ... -
Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties
(2019-02-21)Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the ... -
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 ... -
Selectivity of dopamine D1 and D2 receptor agonists – A combined computational approach
(2012-10-26)Dopamine (DA) is an endogenous neurotransmitter acting in the central nervous system. DA plays a key role in many vital brain functions such as behavior, cognition, motor activity, learning, and reward. Dopamine receptors ... -
Self-organization of nanoparticles - implications for interface biology
(2012-05-03)Cells bind to their surroundings via proteins displayed on the cell surface. These interactions support the cells and are important for many cellular processes, e.g. cell migration during morphogenesis, wound healing and ... -
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 ... -
Simplified Nonsense: New Methods for Interrogating NMD
(2023-02-20)Nonsense mediated decay (NMD) is a pathway that regulates RNA turnover. Since its discovery, this pathway has been implicated in a variety of cellular processes ranging from differentiation to the restriction of viral ... -
Static and Dynamic Measurements of Neurotransmitters in Drosophila Brain
(2012-11-15)Neurotransmitters, the substances neurons use for communication, and their precursors and metabolites are of obvious importance for the wellbeing of the individual and when the neurotransmitter balance is off it can lead ... -
Strong exciton-photon and exciton-exciton coupling and its effects on molecular photophysics
(2022-12-05)The energy of molecular states and their transition dynamics form the key properties to understand the photophysics of organic molecules. Strong exciton-photon and exciton-exciton couplings enable the possibility to ... -
Strong light-matter interaction and its consequences on molecular photophysics
(2020-09-15)Strong light-matter interaction offers the possibility to modify chemical and physical properties of molecules by modifying their photonic environment, resulting in the creation of hybrid light-matter states, known ... -
Structural analyses of immune cell receptor signalling and activation
(2013-04-17)Structural biology is a scientific field where the aim is to observe macromolecules on a atomic level to understand their functions. Often these macromolecules are proteins that make, almost, everything happen within the ... -
Structural and dynamical basis of NusA´s role in transcription-coupled DNA repair
(2022-10-28)DNA repair processes involves a host of repair machineries that are able to recognize and repair the damaged DNA. Nucleotide excision repair (NER) pathway is one of these processes exploited by cells to remove bulky DNA ... -
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 ... -
Structural and Interaction Studies of the Human Protein Survivin.
(2019-03-14)Cell division and cell death (apoptosis) are two essential processes to maintain the specific number of cells in all multicellular organisms. In humans, the misregulation of these processes leads to severe diseases, such ... -
Structural characterization of electron transfer in D.m (6-4) photolyase by time-resolved X-ray crystallography
(2022-10-18)Photolyases are flavoproteins widely spread in bacteria, archea, fungi, plants and animals. These enzymes absorb blue light and use it as an energy source for repairing damages that are induced on DNA after a prolonged ... -
Structural Dynamics of Rhodopsins using Time-Resolved X-ray Solution Scattering
(2022-05-11)Light is one of the most important sources of energy and environmental signals, and many organisms adapt in response to the presence of light. This is made possible through specialised proteins called photoreceptors. ... -
Structural Features of Bacteriophytochromes. Photoactivated Proteins studied by Serial Femtosecond Crystallography
