Dr. Lesego Moitsheki     

Lesego graduated in 2006 under the supervision of Prof. SA. Bourne and Prof. L.R. Nassimbeni . His PhD thesis entitled "Novel hybrid organic/inorganic materials" was based on making crystals of organic-inorganic hybrids. These are compounds known to combine the inherent advantages of both organic and inorganic substances. They possess catalytic effects, gas storage capabilities, could be used for solvent adsorption and separation, water purification, etc. For his research study, a large scope of inorganic compounds was investigated and these include compounds of actinides, lanthanides, transition and main group metals using dipyridyl ligands. Compounds prepared were characterized by x-ray diffractometry. Crystal structures were elucidated using X-SEED program. Thermal analysis (TG, DSC and HSM) was used to determine the thermal behaviour of these compounds. Microanalysis was used to confirm the elemental composition of compound synthesized.
