16. Slag inclusion formation during solidification of steel alloys and in cast iron
Abstract : This thesis explores the formation of segregation and inclusions during solidification of steel and cast iron. A better understanding of the formation mechanism should result in decreasing fraction of defects during solidification of ingot and strand material. READ MORE

17. On the cell cycle of Escherichia coli and cell division in Haloferax mediterranei
Abstract : Escherichia coli has served as a model organism for prokaryotes for several decades and is perhaps the most well characterised organism on earth. The use of fluorescence microscopy during recent years has contributed substantially to our understanding of the essential cell cycle processes chromosome replication, chromosome segregation and cell division.

18. Microstructure of Nickel-Chromium Superalloys
Abstract : The microstructure of nickel-chromium superalloys has been investigated using several advanced microanalytical techniques; atom probe field ion microscopy (APFIM), transmission electron microscopy (TEM) together with energy dispersive X-ray analysis (EDX) and electron energy loss spectroscopy (EELS), secondary ion mass spectroscopy (SIMS) and optical microscopy (OM). The features primarily considered include precipitation, segregation and ordering. READ MORE
