\subsection{Nanoparticles in Poly-(methyl methacrylate / etylhexyl methacrylate) Matrix}
As a second nanoparticle in polymer sample, an Azobisisobutyronitrile (AIBN) initiated methyl methacrylate (MMA)/etylhexyl methacrylate (EHMA) polymerisation with magnetite nanoparticles was performed.
The nanoparticle solution was concentrated to XXX in toluene by precipitation, centrifugation and redispersion. To account for the different iron concentration, to different amounts of the nanoparticle solution and additional toluene, 800\,ul of EHMA was added each (see \fref{tab:sampleCP}). After strong sonication to ensure dispersion, 3.2\,ml of MMA were added and the solution was bubbled with N$_2$ for 5\,min. To start the polymerisation, 20\,mg of AIBN were added and the solution was bubbled again with N$_2$ for 10\,min before heating it up to XXX using a water bath under weak sonication using a sonic bath. The mixture was kept at XXX for XXX.
The vials were uncapped and the polymer dried for 12h at XXX. The polymer was removed from the vials and cut into slices of approximatly XXX thickness using a slow spinning diamond saw.

abstract = {The ability to produce ultrashort, high-brightness X-ray pulses is revolutionizing the field of ultrafast X-ray spectroscopy. Free-electron laser (FEL) facilities are driving this revolution, but unique aspects of the FEL process make the required characterization and use of the pulses challenging. In this paper, we describe a number of developments in the generation of ultrashort X-ray FEL pulses, and the concomitant progress in the experimental capabilities necessary for their characterization and use at the Linac Coherent Light Source. This includes the development of sub-femtosecond hard and soft X-ray pulses, along with ultrafast characterization techniques for these pulses. We also describe improved techniques for optical cross-correlation as needed to address the persistent challenge of external optical laser synchronization with these ultrashort X-ray pulses. This article is part of the theme issue ‘Measurement of ultrafast electronic and structural dynamics with X-rays’.},
