Nanostar 2 saxs

Small-angle X-ray scattering (SAXS) measurements were obtained using the SAXS/WAXS beamline at the Australian Synchrotron, Clayton, Australia, using incident X-ray radiation with λ = 1.0322 Å (12 keV beam) and a Bruker NanoSTAR II SAXS (Bruker AXS, Karlsruhe) using Cu-Kα radiation, λ = 1.5418 Å (45 kV, 110 mA), at ACNS, Lucas Heights, Australia. A detailed explanation of the experimental set-up from the SAXS/WAXS experiment at the Australian Synchrotron is given in the ESI. †

SAXS experiments were performed using a NanoSTAR II SAXS instrument (Bruker AXS, Karlsruhe Germany). The solution samples (prepared in H2O) were loaded into 2 mm ID quartz capillaries and the temperature was maintained at 25˚C. The scattering intensity, I(q) of samples were recorded against the scattering vector, q (equation 1) in the range 0.01 Å -1 to 0.39 Å -1 [34] .
where 2θ is the angle of scattering and λ is the wavelength of the X-ray beam (1.54 Å). The obtained I(q) was radially averaged using routines in the Bruker software. The appropriate buffer and instrument background was subtracted using the PRIMUS computer program [35] .
