11. Use of local electrochemical techniques for corrosion studies of stainless steels
Abstract : The excellent corrosion resistance of stainless steels arises from the presence of a passive film on its surface. Above 10.5wt% Cr a chromium oxide of 1-3 nm is formed on the surface of the metal that in case of damage will reform and hinder further dissolution of the metal. READ MORE

12. A Molecular view of inital Atmospheric Corrosion : In situ surface studies of zinc based on vibrational spectroscopy
Abstract : Atmospheric corrosion takes place on most metals as they interact with thesurrounding environment. A degradation of the metal is the common result,which often leads to a shortened lifespan of the material. READ MORE

15. Application of Rare-Earth Doped Ceria and Natural Minerals for Solid Oxide Fuel Cells
Abstract : Although solid oxide fuel cell (SOFC) technology exhibits considerable advantages as compared to other energy conversion devices, e.g. high efficiency, low emission and fuel flexibility, its high operating temperature leads to rapid component degradation and has thus hampered commercialization.
