Current Research Activities
Physics
Dr Mbule is a hardworking, self-motivated researcher in the field of Nanomaterials and Nanotechnology. In this regard, she has given a number of talks at the national and international conferences. Her research is based on the study of the synthesis and characterization of different nano-composites and fabrication of organic solar cells, which resonates with modern age research in science and addresses to seek avenues for significant energy efficiencies and renewable energy innovation. She is currently involved in the project on development of different metal oxides nano-composites for organic solar cells application at the Department of Physics of the University of South Africa.

TWAS Awards
Feb 2016FellowshipUnder this programme, researchers are assisted in making a ‘Cooperation Visit’ to an institute in Germany. Such visits will have a duration of no more than three (3) months and must be undertaken within 12 months of the award. The aim of the visit is to discuss research collaboration with German scientists with the ultimate goal of developing longer-term collaboration, perhaps through other DFG programmes. TWAS covers visa, health insurance and travel expenses, while DFG will provide subsistence costs for the stay in Germany. The administration and financial operation of TWAS is undertaken by UNESCO in accordance with an agreement between UNESCO and the Italian Government for TWAS.Other Awards
