11. Surface reactions in aqueous metal sulfide systems
Abstract : Surface reactions in aqueous metal sulfide systems have been studied. The composition and stability of various complexes at the PbS-H20 the PbS/H20 and ZnS/H20 interface were evaluated. READ MORE

12. Surface Complexation Studies in An (Th, U(IV), Pu(VI)) Systems
Abstract : Two-phase systems containing an electrolyte solution and a suspended solid were studied. The common denominator for the three systems examined in this work is that they contain actinides (elements of atomic numbers between 89 and 103) in either the solid phase or as a sorbate. Experiments were done on simple oxides. READ MORE

13. Electric Fields for Surface Design and Chemical Analysis
Abstract : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. READ MORE

14. Molecular beam study of non-adiabatic electron transfer in the Cl2+Ksurf surface reaction
Abstract : Halogen molecules impinging on alkali metal surfaces constitute model systems for studies of charge transfer, dissociation dynamics and non-adiabatic energy dissipation in molecule-surface reactions. This thesis reports emission of exo-electrons and photons from the surface as a result of strong non-adabaticity in the Cl2 gas on K$^{solid}$ reaction. READ MORE

15. Graphene: Applications in Surface Science Studies
Abstract : This thesis addresses how graphene can be a valuable asset for surface science studies. Using a combination of X- ray photoelectron spectroscopy, scanning tunneling microscopy, and low-energy electron diffraction, we take advantage of graphene’s sensitivity to changes in its chemical environment to obtain an atomic scale understanding of different reactions occurring above and below the film.
