The complex nano-morphology of modern soft-matter materials is successfully probed with advanced grazing-incidence techniques. Based on grazing-incidence small- and wide-angle X-ray and neutron scattering (GISAXS, GIWAXS, GISANS and GIWANS), new possibilities arise which are discussed with selected examples. Due to instrumental progress, highly interesting possibilities for local structure anal...

Thin photoactive polymer films of poly(3-octylthiophene-2,5-diyl) (P3OT) and poly(2,5-di(hexyloxy)cyanoterephthalylidene) (CN-PPV) are investigated. With X-ray reflectivity measurements, a linear concentration-thickness dependence is found for both polymers and the molecular weight of CN-PPV is determined from this concentration-thickness dependence. Based on the molecular weights, the critical...

The structural characterization correlated to the processing control of hierarchical structure of planar heterojunction perovskite layer is still incomplete due to the limitations of conventional microscopy and X-ray diffraction. This present study performed the simultaneously grazing-incidence small-angle scattering and wide-angle scattering (GISAXS/GIWAXS) techniques to quantitatively probe t...

The design, fabrication and performance of a novel and highly sensitive micro-reactor device for performing in situ grazing-incidence X-ray scattering experiments of model catalyst systems is presented. The design of the reaction chamber, etched in silicon on insulator (SIO), permits grazing-incidence small-angle X-ray scattering (GISAXS) in transmission through 10 µm-thick entrance and exit wi...

A recently synthesized self-doped conducting oligomer, salt of bis[3,4-ethylenedioxythiophene]3thiophene butyric acid, ETE-S, is a novel promising material for green energy applications. Recently, it has been demonstrated that it can polymerize in vivo, in plant systems, leading to a formation of long-range conducting wires, charge storage and supercapacitive behaviour of living plants. Here we...

Supramolecular nanowiring rests on the precise interconnection of nano- or microelectronic circuit elements with electroactive 1D supramolecular polymers. It represents a unique opportunity to access miniaturized organic electronic devices. The bottom-up construction such integrated nanowires can be in principle generated by addressing polymerization process spatial precision that cannot access...

Organic semiconductors have seen widespread application in thin-film devices, such as organic field-effect transistors (OFETs), whose performance is closely linked to the molecular-level microstructure and crystalline orientation. In actual OFETs, varies significantly based on local environment, for example, proximity of contact electrodes. This account highlights recent examples where microfoc...

For optoelectronic applications of metal–organic framework (MOF) thin films, it is important to be able fabricate films and heterostructures that are highly oriented relative the substrate's surface normal. However, process optimization achieve this difficult without sufficiently detailed structural characterization deposited films. It demonstrated 2D grazing-incidence wide-angle X-ray scatteri...

We have fabricated a bifocal miniature torodial mirror that horizontally and vertically focuses to two different locations to provide a smaller footprint of beam for grazing-incidence wide-angle scattering (GIWAXS), while at the same time focusing the beam in the horizontal direction on the detector to further enhance the angular resolution. At CHESS we traditionally use glass single-bounce mon...
