“…With both lead and bismuth being isoelectronic and active species in the reaction mixture, our synthesis gives access to compounds within the ternary PbS–Bi 2 S 3 system for the domain grown on the perovskite seed. Compounds in this PbS–Bi 2 S 3 system have been investigated as NCs and in bulk for their thermoelectric properties, , but the variation of the composition might also allow a facile tuning of the band gap. , In essence, the introduction of bismuth results in the formation of NC heterostructures made of two domains: a prismatic CsPbBr 3 perovskite domain and an elongated Pb x Bi y S z chalcogenide domain. These NC heterostructures are investigated by advanced electron microscopy to identify their three-dimensional shape, and the progress of the reaction is followed by in situ and ex situ experiments to investigate their formation.…”

The CaGSUMI consortium was funded by the Royal Society–Department for International Development (later the Foreign, Commonwealth & Development Office) on the Africa Capacity Building Initiative programme between the years 2015 and 2022 and involved three Sub-Saharan African universities: Kwame Nkrumah University of Science and Technology, Kumasi, Ghana, University of Yaoundé I, Cameroon, and the University of Zululand, South Africa; and the University of Manchester in the United Kingdom. The project was used to cement an emergent UK–Africa network in the areas of materials chemistry related to renewable energy generation with both thin films and nanomaterials. The consortium’s outputs led to numerous publications of African science in international journals, a number of graduated PhDs who went on to permanent academic positions and prestigious fellowships, the establishment of a capacity-building plan relevant to the chemistry departments in each of the African countries, and the installation of a number of first-in-kind pieces of kit for African laboratories that will keep them on a competitive footing at an international level for the next decade and more.
