1. This course unit aims to endow students with advanced knowledge in Surfaces and Interfaces, together with skills in the interpretation of physical and chemical phenomena and textural characterization of porous materials.
2. A holistic and interdisciplinary approach to problems will be used.
3. This course unit also aims to develop students’ critical and creative spirit.
1 - To adquire knowledge about surfaces and interfaces.
2 - To adquire skills to interpret current physico-chemical phenomena and to characterize porous materials.
Theoretical-practical classes :
TP1 - Chemistry and Physics of Surfaces.
Surface tension and contact angle;
Laplace, Kelvin and Young equations;
Cohesion, adhesion and spreading;
Insoluble monolayers;
Adsorption from solution: Gibbs equation.
TP2 - Textural Characterization of Porous Materials.
Equilibrium and adsorption isotherms;
Analysis of physical adsorption isotherms: B.E.T method;
Standard isotherms;
Capillary condensation and evaporation;
Adsorption in microporous solids.
Selected laboratory experiments:
PL1 - Study of the adsorption of carboxylic acids on activated carbon.
PL2 - I. Determination of the surface tension of water and aqueous solutions of amphiphilic compounds. II. Study of the adsorption of amphiphilic compounds at the liquid-liquid interface.
PL3 - I. Determination of the contact angle of water on different solid surfaces. II. Study of the effect of the addition of a salt (NaCl) and a surfactant (sodium dodecyl sulfate, SDS) on the contact angle of water.
Classes will be based on the presentation of the theoretical-practical themes of the course unit. In some of the theoretical-practical classes, exercises will be discussed and solved.
In the laboratorial classes, experimental work will be carried out where the students can apply the knowledge acquired in theoretical-practical classes.

To be admitted to tests, students cannot miss more classes than allowed by the appropriate regulations.
Final grade (C) will be based on the formula: C=0.70(T1+T2)+0.30P
T1 – 1st test (T1max=10)
T2 – 2nd test (T2max=10)
P – laboratory grade (Pmax=20)
Minimum values of 9 and 10 are required for (T1+T2) and P, respectively.
The improvement of the laboratory grade (P) is not allowable.
However, the students may increase the final grade by being present in an exam corresponding to the theoretical-practical component. In this case, the final grade will be calculated by the formula C=0.70E+0.30P, where:
E – exam (Emax=20; a minimum value of 9 out of 20 is necessary).
Unsuccessful students, who attended this course unit in the previous academic year, do not need to attend classes (but they can attend as many classes as they want). However, they should be present in the two tests (T1 and T2) and/or in the exam (E) if necessary. In the calculation of the final grade, the value of P obtained in the previous year (if positive, i.e. >=10) will be considered.
Students have to attend an exam at the appropriate season. Their grades will be based on the classification achieved in the exam.
In order to improve their grades, students have to attend an exam, which will be as the final exam for unsuccessful students.
