Interfaces and Catalysis
After this course the student is able to:
a) analyse experimental data (like concentration changes in time) to find kinetic parameters like the activation energy, half-life time, reaction orders and rate constants.
b) apply simple approximations (like the steady state approximation) to find rate laws from a given mechanism
c) describe the central ideas in colloid science like surface energy, adsorption, wetting, surface potential, electro-osmosis, electrophoresis and colloidal stability.
d) use expressions for capillary rise / pressure, adsorption isotherms and electrical double layers with experimental data
e) understand the assumptions of the Langmuir and BET adsorption isotherms and their effect on the specific surface area; with given data (adsorbed amount versus (relative) pressures) the student should be able to calculate the specific area of a surface understand the assumptions of Langmuir-Hinshelwood en Eley-Rideal mechanisms and can calculate
their effect on reaction kinetics
g) describe the central ideas in transport of the reactants/products to/from the catalyst: Molecular and Knudsen diffusion, internal and external mass transfer limitations, Thiele modulus.
h) predict the apparent activation energy for a catalyzed reaction in the case of no/internal/external mass transfer limitations
i) describe and interpret results from important characterization techniques (chemisorption, electron microscopy, STM, XRD, XPS, LEED)
The rapid development of materials science and engineering has enabled the development of new devices that operate due to the combination of materials with different functionalities. Often different functionalities have been combined in one material as for example transparent and electrically conducting electrodes required for solar panels. Similar examples of the use of engineered materials with complex functionalities can be found in such diverse areas as IC-, battery, imaging, and sensor technology, and in the application of biomaterials, elastomers, polymers etc. Successes in all these fields were the result of systematic research and development based on a thorough understanding of the relation between material properties on the hand and the structure and composition on the other hand. With this knowledge, the synthesis of the desired materials could be tuned. The 2014 Nobel prize in physics is a prime example of this methodology that resulted in the invention of the blue led. This methodology is visualized with the two legs of the materials science triangle:
In this module the students will learn:
- How properties of materials are related to structure and composition.
- How synthesis can be tuned to accommodate a desired structure and composition.
- To apply materials science in a competitive field.
One example is the application of this knowledge in the field of sensor technology in an elastomeric matrix. The module requires a basic understanding of materials as is part of the curriculum of Advanced Technology, Applied Physics, Electrical Engineering, Mechanical Engineering, Chemical Engineering and Biomedical Engineering. This HTHT module shares 1/3 of its courses with a second year AT module and also takes the materials science triangle as its starting point with different application areas (IC-technology, Catalysis). This knowledge is complimented by a dedicated class on composite materials on nano, micro and macro scale, including innovative material functionalities as e.g. sensor- and actuator technology. This HTHT module discerns itself from this standard module with the strong link to current industrial research through the input from invited speakers from industry and a strong integrating project.
