Researchers from Tanzania conducted an experiment to stabilize cadmium sulphide quantum dots with the help of castor oil and ricinoleic acid. Cadmium sulphide quantum 
dots capped with castor oil and ricinoleic acid were prepared and analysed using various characterization techniques.
Results from all the characterization studies confirmed the formation of spherical shaped castor oil and ricinoleic acid capped cadmium sulphide quantum dots.
