Abstract (Περίληψη)

In the first part we explore the rotating lepton model that was first suggested by C.G. Vayenas and S. Souentie. This model has the ability to agree with many of the predictions of the Standard model but without use of adjustable parameters. Beyond the usefulness as a predicting tool, the fact that this model is based on first principles suggests that it contains a substantial amount of truth and thus warrants an in-depth review and analysis. Starting from the newtonian concepts of gravitation and space-time we explore the influence of special relativity and follow the line of thought of the model which ultimately claims that nuclear forces are the relativistic facets of gravity. Several examples are analyzed.

In the second part we study the reaction of CO2 hydrogenation in terms of its importance in the energy-management field and conduct several experiments in order to cast light in the role of metal -support interactions in the heterogeneous catalysis of the reaction.
