Prerequisites
Not applicable.

Objectives
Students should be able to describe the major models used to describe the physical and chemical behaviour of surfaces and interfaces. They should be able to apply these concepts to important chemical technology systems.

Program
1.Colloidal Systems. Industrial importance; 2.Liquid/gas interface. Surface tension. Young-Laplace equation. Kelvin equation. Gibbs isothermal; 3. Liquid/liquid interface. Interfacial tension. Aggregation and tensioactive colloids. Emulsions. Bancroft rule; 4.Solid/gas interface. Chemical and physical adsorption. Adsorption isothermals. Langmuir and BET
models.

Evaluation Methodology
Short individual written essay on a topic related with surface and interface chemistry and reports (30%). A written mid-term test or final examination (70%).
