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.

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.

Growth of LTA zeolite nanoclusters using a block copolymer template

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.

Nanomaterial coatings: controlling and analyzing thin films of lipid cubic phase

We have studied new forms of a nanomaterial known as a LCP (Lipid Cubic Phase), preparing them as thin films rather than the bulk gels or liquids typically used.

Response of the wurzite GaN surface to swift heavy ion irradiation

Ion tracks on wurzite GaN surface were investigated after exposure to grazing incidence swift heavy ion (SHI) beams. Structural investigations by atomic force microscopy (AFM) and grazing incidence small angle X-ray scattering (GISAXS) were complemented by monitoring stoichiometry changes using in situ time-of-flight elastic recoil detection analysis (TOF-ERDA).

Polymer/Nanocrystal Hybrid Solar Cells: Influence of Molecular Precursor Design on Film Nanomorphology, Charge Generation and Device Performance

The morphological and optoelectronic properties of polymer/nanocrystal hybrid (pnh) solar absorber layers can be significantly influenced by small modifications of the chemical structures of the precursor molecules. Pnh solar cells are an interesting concept due to the incorporation of the attractive qualities of both organic and inorganic materials.
