6. Gas-Phase Protein Structure Under the Computational Microscope : Hydration, Titration, and Temperature
Sammanfattning : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. LÄS MER
7. Statistical processing of Flash X-ray Imaging of protein complexes
Sammanfattning : Flash X-ray Imaging (FXI) at X-ray Free Electron Lasers (XFELs) is a promising technique that permits the investigation of the 3D structure of molecules without the need for crystallization, by diffracting on single individual sample particles.In the past few years, some success has been achieved by using FXI on quite large biological complexes (40 nm-1 μm in diameter size).

8. Flash Diffractive Imaging in Three Dimensions
Sammanfattning : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.

9. Small Particles with Big Impact : Structural Studies of Viruses and Toxicological Studies of Nanodiamonds
Sammanfattning : Nanoparticles (NPs) can be found everywhere and their existence has both beneficial and harmful consequences for the environment and living beings. The investigations on which this thesis is based upon have contributed to an increased understanding of some of these particles and to the development of a method that could be used to study their structure.

10. Protein Folding Simulations in Kink Model
Sammanfattning : The structure of protein is essentially important for life activities. Proteins can perform their functions only by specific structures. In this thesis, the kink and multi-kink model for protein description are reviewed. LÄS MER
