 The goal of this tutorial is to create a system made of 
-carbon nanotubes (CNTs) embedded in a polymer melt made in nylon-6,6. The
+carbon nanotubes (CNTs) embedded in a polymer melt made in nylon-6,6 (Fig.\,\ref{fig:REACT}). The
 REACTER protocol is used to simulate the polymerization of nylon, and the formation
 of water molecules is followed in time \cite{gissinger2020reacter, gissinger2024molecular}.
