+    \begin{itemize}
+      \item Significant technological progress
+            in 3C-SiC wide band gap semiconductor thin film formation [1].
+      \item New perspectives for processes relying upon prevention of
+            precipitation, e.g. fabrication of strained pseudomorphic
+           $\text{Si}_{1-y}\text{C}_y$ heterostructures [2].
