Status and trends in advanced instrumentation for Small- and wide-angle x-ray scattering

Small- and wide-angle x-ray scattering are widely-used, powerful techniques for investigating hard and soft condensed matter in bulk, thin film and at interfaces [1,2]. Especially the combination with advanced micro- and nanofocusing as well as complementary methods and in-situ combinations with advanced sample environments allow for extracting the structure-function relationship of various materials’ classes, especially during their nanoscopic build-up processes. This allows for correlating the structural build-up at the nanoscopic and mesoscopic length scales. Based on recent experiments, I will present specific examples from the field of nanocomposite functional materials. In detail, I will cover experiments using microfluidics, imaging ellipsometry, tomography and sputter deposition [3-6]. Finally, I will give an outlook on near-term implementations of advanced instrumentation and characterization capabilities at PETRA III [7].
