About this collection
Graphene has become a tool that can open new research lines in all branches of science. This collection of articles, guest edited by Associate Editor Pablo Denis (Universidad de la Republica Oriental del Uruguay), covers a wide range of topics and reflects the broad spectrum of authors and readers of RSC Advances, including Nobel Prize winners. It includes contributions on catalysis, drug delivery, sensing, renewable energies, synthesis, theoretical chemistry, water purification, thermal/mechanical properties, polymer chemistry, cancer treatments and even microwave radiation protecting materials. It is our expectation that this collection can elicit new investigations about graphene-based nanomaterials, as well as new submissions.
