Molmet

The SAXS data were collected using a pinhole camera (MolMet, Rigaku, Japan, modified by SAXSLAB/Xenocs) on a microfocused X-ray beam generator (Rigaku MicroMax 003) operating at 50 kV and 0.6 mA (30 W). Vacuum version of a Pilatus 300 K detector was used with the camera. Primary beam position and sample-to-detector distances were calibrated using an AgBehenate sample. Borosilicate capillaries were used as measurement containers for the samples. To cover the range of scattering vectors (q) from 0.005 to 1.100 Å⁻¹, two experimental settings were used.
$q=\frac{4\pi }{\lambda }\sin \theta$
where 2 $\theta$ is the scattering angle, and $\lambda$ is the incident wavelength.
We chose 22 °C and 40 °C as the measurement temperatures to obtain data throughout the thermally induced self-assembly process. Obtained scattering data were reduced using software based on the PyFAI Python library [42 (link)], and SASFit [43 (link)] and SASView [44 (link)] were used to fit the data.

Wide-angle X-ray scattering (WAXS) experiments were performed using a pinhole camera (MolMet, Rigaku, Japan, modified by SAXSLAB/Xenocs) attached to a microfocused X-ray beam generator (Rigaku MicroMax 003) operating at 50 kV and 0.6 mA (30 W). The camera was equipped with a vacuum version of Pilatus 300K 2-dimensional detector. Calibration of primary beam position and sample-to-detector distances was performed using Si powder sample. Experimental setups covered the scattering vector, q = (4π/λ)sinΘ, where λ is the wavelength and 2Θ is the scattering angle, in the range 0.22–1.42 Å⁻¹. Homemade software based on PyFAI Python library (doi:10.1088/1742-6596/425/20/202012) was used for data reduction. Samples were measured in reflection mode with incident beam angle set to 1.3 degree.
