Austrian SAXS beamline at Elettra

Small Angle X-ray Scattering is a non-destructive and highly versatile standard method to study the nanoscale structure of any type of material ranging from new composite nanosystems to biological macromolecules. Parameters as (i) averaged particle sizes, shapes and distributions, (ii) the materials' porosity and degree of crystallinity as well as (iii) electron density maps with nanometer precision can be obtained. Materials can be solid, liquid or even exhibit gaseous-like properties as for instance aerosols.

The highflux SAXS beamline at Elettra has been built by the Institute of Biophysics and Nanosystems Research (IBN), Austrian Academy of Sciences, and is in user operation since September 1996. On 1st October 2012 the beamline was transfered from the IBN to the Institute of Inorganic Chemistry of Graz University of Technology.
The beamline was mainly intended for time-resolved studies on fast structural transitions in the sub-millisecond time region in solutions and partly ordered systems with a SAXS-resolution of at least 100 nm in real-space. But increasingly also grazing-incidence (GISAXS) measure- ments are performed to study self-assembly processes on surfaces, or to perform structural characterisations of thin films. Additionally SAXS measurements can be coupled to simultaneous Differential Scanning Calorimetry (DSC) and Wide Angle X-ray Scattering (WAXS) recordings. Users have the possibility to use our various sample holders (e.g., rapid mixing; T-jump; pressure cell), or to install their own specialized sample equipment.

Highly Luminescent Metal-Organic Frameworks Through Quantum Dot Doping

The incorporation of highly luminescent core–shell quantum dots (QDs) within a metal–organic framework (MOF) is achieved through a one-pot method. Through appropriate surface functionalization, the QDs are solubilized within MOF-5 growth media.

Evolution of the protein corona of lipid gene vectors as a function of plasma concentration

The effective unit of interest in cell-nanomaterial interactions is not the nanoparticle itself but the particle and its hard corona of associated proteins from plasma or other bodily fluids.

Avoiding the Raft: Losartan´s Affinity to Fluid Bilayers

We examined losartan’s action in different biomimetic membrane models. Losartan is an angiotensin II receptor antagonist mainly used for the regulation of high blood pressure, and structural details on its incorporation into the biomembrane interface have been studied by small angle X-ray scattering. We found that losartan tends to avoid cholesterol-rich membrane domains.

How to prepare sphere- and rod-like ZnO particles?

We propose a growth mechanism that follows a “nonclassical crystallization” concept for the self-assembling mechanism of approximately 10-nmsized building units into peanut-like ZnO and/or microsphere-like hydrozincite particles.

Structure and morphology of magnetron sputtered W films

The structural and morphological details of magnetron sputtered tungsten (W) thin films as a function of the Ar working gas pressure and the sputtering power are presented. The crystal structure of the W films was examined with grazing incidence x-ray diffraction (GIXRD), while the morphology characterization was performed by x-ray reflectivity (XRR) and grazing incidence small-angle x-ray scattering (GISAXS).

Control of lipid structuring by trans- and cis-fatty acids

Exploring the effect of these two fatty acids on biological membrane structures is of great interest due to the implications of their daily consumption in vital biological processes related to health and disease, and their role in designing gel-like formulations for controlling the release of drugs or functional foods.

Employment of highly branched copolymer micelles as core substrate to control the soft interactions at the boundary between organic and inorganic domains provides a steric stabilization that enhances the colloidal stability during LTA zeolite formation. Our results are important for optimizing porous materials production.
