Materials and Nanoscience

The materials and nanoscience (M&N) group is primarily focused on the study and development of new coordination compounds, applications and crystallographic studies of metal organic frame works (MOFs), chemical processes in nanomaterials growth, unique properties of nanosystems, novel in-situ characterisation techniques and applications of nanomaterials.

We are also interested in the dynamics of catalyst contamination, fluid catalytic cracking (FCC) technology,biological activity of coordination compounds with antioxidant and mosquito larvicidal properties. Moreso, integration of nanomaterials with biomass and minerals via chemical and biological routes in addition to surface functionalisation for specific environmental waste streams is actively explored.

The highly interdisciplinary and encompassing nature of the group supports and welcomes contributions from engineers, microbiologists, botanists, industry experts as well as soil scientists. This has opened up vistas of opportunities and innovation into this emerging research landscape.

One of the group’s strength is its extensive collaboration networks both within Nigeria and the international scientific community through Chemistry Department at University of Johannesburg, Lancaster Environment Centre at Lancaster University, State Key Laboratory of Heavy Oil processing at China University of Petroleum (East China) and the International Environmental Research Centre at Gwangju Institute of Science and Technology (GIST) South Korea, etc. to drive our mandate of achieving goal six of the United Nations Sustainable Development Goals (SDGs)

Nanotechnology and material science lie at the centre of many challenges facing society today, from energy to health, water to agriculture which stimulates our work in the M&N group. Most of our research have global relevance and have attracted funding supports from many organisations such as the TETfund, American Chemical Society (ACS), United Nations Office for South-South Co-operation, etc.
