1. On the Volume Changes during the Solidification of Cast Irons and Peritectic Steels
Abstract : This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. READ MORE

3. Aqueous behaviour of characteristic molecules in the synthesis of porous silica materials : - an atomistic description
Abstract : The formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. READ MORE
