The Centre for Advanced 2D Materials (CA2DM), at the National University of Singapore (NUS), is the first centre in Asia dedicated to graphene research.^[1] The Centre was established under the scientific advice of two Nobel Laureates in physics – Prof Andre Geim and Prof Konstantin Novoselov - who won the 2010 Nobel Prize in Physics for their discovery of graphene.^[2] It was created for the conception, characterization, theoretical modeling, and development of transformative technologies based on two-dimensional crystals, such as graphene.^[3] In 2019, Prof Konstantin Novoselov moved to Singapore and joined NUS as Distinguished Professor of Materials Science and Engineering.^[4]

History and funding[]

CA2DM had its beginnings in 2010 as the Graphene Research Centre (GRC),^[5] which NUS established under the leadership of Prof. Antonio H. Castro Neto, with a start-up fund from NUS of S$40 Million, 1,000 m2 of laboratory space,^[6] and a state-of-the-art clean room facility of 800 m2.^[7] In June 2012, the GRC announced the opening of a S$15 Million micro and nano fabrication facility to produce graphene products.^[8] Then in 2014, research activities in the GRC expanded to other 2D materials such as 2D transition metal dichalcogenides. To better reflect the research activities, the GRC was renamed the Centre for Advanced 2D Materials (CA2DM), and became an NRF “Medium-Sized Centre", with a S$50 Million grant.^[9] Speaking of commercial application today scientists are using graphene for making synthetic blood and developing non-invasive treatments for cancer. Graphene would soon replace silicon in your computer chips thus resulting in a much faster, unbreakable tablets, phone and others;^[10] CA2DM is also participating on a S$50 Million CREATE grant from NRF, together with University of California, Berkeley and Nanyang Technological University, for the study of new photovoltaic systems based on two-dimensional crystals.
