Effects of phosphonium-based ionic liquids on phospholipid membranes studied by small-angle X-ray scattering.
The effects of ionic liquids on model phospholipid membranes were studied by small-angle X-ray scattering, dynamic light scattering (DLS) and zeta potential measurements. Multilamellar 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine liposomes and large unilamellar vesicles composed of l-α-phosphatidylcholine (eggPC) and l-α-phosphatidylglycerol (eggPG) (80:20mol%) or eggPC, eggPG, and choleste...
متن کاملCharacterization of track-etched membranes by small-angle x-ray scattering
Track-etched membranes are polymer foils irradiated with swift heavy ions and subsequently wet-etched to create pores by dissolving defects formed along the ion trajectories. Under suitable conditions, the resulting pores are of cylindrical shape and uniform in size. Such membranes are commonly used for filtration or as templates for nanowires, grown inside the pores, e.g., by electrochemical d...
متن کاملDetermination of the ion track structure in amorphous SiO2 using small angle x-ray scattering
In amorphous SiO2 (a-SiO2), a technologically most important material, average structural properties of ion tracks have been inferred from macroscopic measurements, yet details of the track structure and inner morphology are difficult to retrieve due to the lack of sufficient contrast inherent with most techniques. Here we report on measurements of a fine structure in ion tracks in a-SiO2 using...
متن کاملOnline ion-exchange chromatography for small-angle X-ray scattering
Biological small-angle X-ray scattering (BioSAXS) is a powerful technique to determine the solution structure, particle size, shape and surface-to-volume ratio of macromolecules. However, a drawback is that the sample needs to be monodisperse. To ensure this, size-exclusion chromatography (SEC) has been implemented on many BioSAXS beamlines. Here, the integration of ion-exchange chromatography ...
متن کاملApplication of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues
ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
