The interactions which occur between both polar and non-polar fluid phases and surfaces of various carbon materials: Activated Carbon (AC), non-porous Carbon Black (CB) and Multiwall Carbon Nanotubes (MWCNTs)with different surface chemistry have been studied. These are currently…

Catalytic events are ubiquitous throughout the study of chemical processes. A catalyst is responsible for lowering activation energies for reactions that otherwise would be unfavorable under typical reaction settings. While there has been substantial progress in the field, a com…

In this thesis, graphene (i.e. monolayer carbon film) and carbon clusters supported on a transition metal surface are systematically studied by local probe techniques, with respect to their structures, electronic properties and formation mechanisms. The main tools used are low-t…

The adsorption of biologically active molecules, such as the DNA bases, amino acids, on solid surfaces has been the subject of a number of experimental and theoretical studies in the past years. The understanding of the self-assembly mechanism of bioactive molecules on surfaces …

Recently there has been significant interest in incorporating molecular elements into electronic devices for electronics, memory, and chemical/biological sensing applications. To date much of the work on this topic has utilized metal electrodes however using silicon (Si) present…
