- Description: A series of novel cadmium complexes has been synthesized from the reaction of cadmium chloride, bromide and iodide with primary aromatic amines. The complexes are either mononuclear or polynuclear according to the nature of the halide and amine employed. A possible mechanism for their formation is proposed. The N - H stretching and bending frequencies are linearly related to the electronegativity of the co-ordinated halogen, indicating that the electron withdrawing capacity of the halogen is transmitted through the cadmium atom.

- Description: Dr. Nyokong’s is the director of the Nanotechnology Innovation Center at Rhodes University, South Africa and the first South African scientist to win the L’Oréal-UNESCO award for women in science. Her research focus on the development of molecules similar to the ones used to dye blue jeans, which can be used as chemical sensors to detect disease-related molecules and organisms, as an alternative to chemotherapy for the treatment of cancer and for environmental clean-up. [Don't miss the video at the end where she talks about her path and research].
