“…Knowledge of the mechanisms involved in nanoparticle formation and growth during metal sputtering onto nanostructured block copolymer thin films is important for identifying appropriate metal sputtering conditions. Early experiments were carried out in a stopsputter mode, in which the metal was sputter-deposited onto the substrate at a certain deposition rate for a few seconds and two-dimensional GISAXS maps were collected after each sputtering step (Metwalli et al, 2008;Kaune et al, 2009;Buffet et al, 2011). Recently, real-time GISAXS data were acquired during the sputtering process (Schwartzkopf et al, 2013;Metwalli et al, 2013).…”

In situ and in operando studies are commonplace and necessary in functional materials research. This review highlights recent developments in the analysis of functional materials using state-of-the-art in situ and in operando X-ray and neutron scattering and analysis. Examples are given covering a number of important materials areas, alongside a description of the types of information that can be obtained and the experimental setups used to acquire them.

Polyaniline (PANI) was synthesized by the oxidative polymerization of aniline with potassium dichromate as an oxidant. PANI was characterized by IR, UV, and TG. The effect of inclusion of CoCl 2 , NiCl 2 , and FeCl 3 on the thermal and optical properties of polyaniline has been studied. The results showed that the doped PANIs are thermally more stable than the pure PANI. The optical band gap of the doped PANIs is smaller than the pure polymer. PANI has higher corrosion inhibition of Al than the doped polymers. Doped PANIs have been used as molecular precursors for the production of Co 3 O 4 , NiO, and Fe 2 O 3 nanoparticles by thermal decomposition route. The structures of the obtained metal oxides have been characterized by XRD and TEM. The average sizes of the prepared nanoparticles were estimated as 22, 17, and 13 nm for Co 3 O 4 , NiO, and Fe 2 O 3 samples, respectively.

“…It allows bottom-up fabrication of designed compounds and morphologies with tailored catalytic, optical, or magnetic properties. [5][6][7][8][9][10][11][12][13] Radio Frequency (RF) sputter deposition is an industrial process extensively used to deposit thin films and, complementary to Direct Current (DC) sputter deposition, it allows to deposit both conducting and non-conducting materials. 14 In order to better control and optimize the deposition process, it is essential to understand the kinetic phenomena involved in the thin film formation.…”

HASE (Highly Automated Sputter Equipment) is a new mobile setup developed to investigate deposition processes with synchrotron radiation. HASE is based on an ultra-high vacuum sputter deposition chamber equipped with an in-vacuum sample pick-and-place robot. This enables a fast and reliable sample change without breaking the vacuum conditions and helps to save valuable measurement time, which is required for experiments at synchrotron sources like PETRA III at DESY. An advantageous arrangement of several sputter guns, mounted on a rotative flange, gives the possibility to sputter under different deposition angles or to sputter different materials on the same substrate. The chamber is also equipped with a modular sample stage, which allows for the integration of different sample environments, such as a sample heating and cooling device. The design of HASE is unique in the flexibility. The combination of several different sputtering methods like standard deposition, glancing angle deposition, and high pressure sputter deposition combined with heating and cooling possibilities of the sample, the large exit windows, and the degree of automation facilitate many different grazing incidence X-ray scattering experiments, such as grazing incidence small and wide angle X-ray scattering, in one setup. In this paper we describe in detail the design and the performance of the new equipment and present the installation of the HASE apparatus at the Micro and Nano focus X-ray Scattering beamline (MiNaXS) at PETRA III. Furthermore, we describe the measurement options and present some selected results. The HASE setup has been successfully commissioned and is now available for users.
