Period
1st semester (01/10/2016 - 20/01/2017)
Lesson hours
48 lesson hours
Prerequisites
Basic thermodynamic notions, spectroscopy and crystallography
Learning outcomes
The students must know the main surface properties, the three fundamental equations of surface chemistry and distinguish the different kind of interfaces. The students should be able to describe the main matemathical models of adsorption. In addition, must known the main techniques to study the surface and interfaces of materials
Course contents
Different kinds of interfaces. Liquid-gas interface and surface tension concept and its experimental determination. Surface films on liquid substrates. Solid-liquid-gas interface and contact angle. Main interface phenomena: friction and lubrication, detergency, bagnability, emulsions and aerosols. Solid-gas interface. Physisorption and chemisorption of gases on solids and isothermal models. Eterogenous catalysis by referring to some model reactions. Experimental methods to study the surfaces: XPS, SEXAFS, ReflEXAFS, surface diffraction, Crystal Truncation Rods, X-Ray Standing Waves.
