Welcome to Surface and Interface Lab !

Dr. Chen Wei's Surface and Interface Lab was established at the Department of Chemistry, National University of Singapore, from Jan 2009. The current research interests of our lab include Molecular-scale Interface Engineering for Molecular, Organic and Graphene Electronics, and Interface-Controlled Nanocatalysis for Energy and Environmental Research. Our research has been substantially supported by NUS, Singapore MOE Tier I and Tier II grants, NRF CREATE and CRP programs and SPORE program.
