Objectives

Knowing different processing techniques of powders, fibers, nanoparticles and thin film growth. Identifying advantages and limitations of the different techniques depending on whether the type of material to obtain both of the process itself. Knowing the importance of process parameters and know how to make the selection of the most suitable process parameters for processing a given material. Knowing the selected technologies to be used according to the type of material to be obtained. Flatten the processing steps according to both the characteristics of the material to obtain both the desired application.

Subject matter

Module 1 - Powder Technology

- Desirable characteristics of a powder material processing.

- Methods for the preparation of powders. Methods for preparing powders by solid state reaction. Methods for preparing powders by liquid solutions.

- Characterization of powders. Classification of the types of particles. Physical classification. Chemical characterization.

- Characterization and structural characterization of the surface.

 

 

Module 2 – Production of nanostructures

- Preparation of different types of nanostructures

   :: Metallic nanoparticles

   :: Metallic oxide nanoparticles

   :: Metallic oxide nanofilms

- Influence of the production parameters

- Applications of nanostrutures

 

 

Module 3- Electrospinning.

- Physical principles.

- Parameters of process control

- Materials and their characteristics;

- Production of polymeric and ceramic nanofibers (in combination with sol-gel process).

Bibliography

During each module of the course, the lectures will indicate related bibliography and will provide supporting literature (eg. papers and  copies of the slides used in the lectures)

Teaching method

Theoretical-practical classes (with computerized environment). These classes may include problem-solving and case studies.

Laboratory classes (given in different laboratories DCM, corresponding to each of the modules).

Evaluation method

The evaluation of the course will be taken in each of the constituent modules.

The assessment for each module consists of a written test (E) and an assessment of the practical component of that module (P).  The evaluation test writing (E) may be done by testing at the end of the module, or by exam.

Note Module I (M1)

In the case of the I evaluation is done by a test with theoretical and practical components. Being the practical component focused on the work performed in the laboratory.

Note Module II (M2)

In the case of module II evaluation is done by a test  with theoretical and practical components. Being the practical component focused on the work performed in the laboratory.

Note Module III(M3)

In the case of module III  evaluation is done by a test  with theoretical and practical components. Being the practical component focused on the work performed in the laboratory.)

 

The final grade (N)

N = (s1*M1+ s2*M2 + s3*M3)/(s1+s2+s3)

wherein  s1, s2 and s3 are the number of weeks of each module, and M1, M2 and M3 are the scores obtained in each one of the modules

To pass the subject, N has to be equal or greater than 10,  with  frequency at the laboratorial classes in each module.

In order to improve the score, the students must register in the Exame, and will be evaluated on all the subjects of the 3 modules.
