A paper by Peter Wilson et al. Three-dimensional periodic graphene nanostructures is one of the 30 most accessed articles in Journal of Materials Chemistry C in 2014. This study demonstrates the possibility of fabricating complex 3D graphene nanostructures by growing graphene on pre-synthesized nanostructured metal templates by chemical vapor deposition and then etching away the metal. Congratulations, Peter!
A paper by Peter Wilson et al. was published in ACS Applied Materials & Interfaces. This study shows that graphitic coatings, which consist of multilayer disordered graphene sheets, can be used for the thermal protection of delicate metal nanostructures. We studied cobalt slanted nanopillars grown by glancing angle deposition that were shown to melt at temperatures much lower than the melting point of bulk cobalt. After graphitic coatings were conformally grown over the surfaces of Co nanopillars by chemical vapor deposition, the resulting carbon-coated Co nanostructures retained their morphology at elevated temperatures, which would damage the uncoated structures. Thermal stabilization was also demonstrated for carbon-coated Ti nanopillars. The results of this study may be extended to other metallic and possibly even nonmetallic nanostructures that need to preserve their morphology at elevated temperatures in a broad range of applications.
Great job, Peter!
UNL Communications has published a press release about this study.
The improvements in random access memory that have driven many advances of the digital age owe much to the innovative application of physics and chemistry at the atomic scale.
Accordingly, a team led by UNL researchers has employed a Nobel Prize-winning material and common household chemical to enhance the properties of a component primed for the next generation of high-speed, high-capacity RAM.
The team, which published its findings in the Nov. 24 edition of the journal Nature Communications, engineered and tested improvements in the performance of a memory structure known as a ferroelectric tunnel junction.

Alexander Sinitskii has been awarded the Harold and Esther Edgerton Junior Faculty Award. The honor is presented each year to recognize an outstanding junior faculty member who has demonstrated creative research, extraordinary teaching abilities and academic promise.
A paper on the bottom-up solution synthesis of atomically precise graphene nanoribbons by Timothy Vo et al. was published in Nature Communications. This study demonstrates a novel bottom–up approach that yields gram quantities of high-aspect-ratio graphene nanoribbons, which are only ~1 nm wide and have atomically smooth armchair edges. These ribbons are shown to have a large electronic bandgap and can be potentially used for the fabrication of electronic devices.
Great job, Tim!
