Course detail

Laboratory Classes in Instrumental and Structure Analysis - MS

FCH-MCA_ISA_MAcad. year: 2019/2020

Students are practically introduced with basic methods used for uncovering, observation and evaluation of supramolecular structure of polymer materials. The practices serves for introduction with selected methods and the last class is dedicated to students self-measurement and characterization of one type of thermoplastic polymer material coming from industry. The students choose two suitable methods because no one is absolute and set proper conditions for measurements. Selected are methods from microscopy, spectroscopy and thermal analysis. The stress is, above all, laid on the importance of proper preparation of a specimen, suitable setting of testing conditions and accurate evaluation and interpretation of the obtained data, but quality of written report, it means coherence and intelligibility, is classified too.

Learning outcomes of the course unit

The ability of students to prepare specimens for imaging on POM and CLSM, for measurements on DSC and FTIR-ATR, and to interpret the observed morphology and the obtained data.

Planned learning activities and teaching methods

The course uses teaching methods in form of Laboratory exercise - 4 teaching hours per week. The e-learning system (LMS Moodle) is available to teachers and students.

Assesment methods and criteria linked to learning outcomes

The classified credit is awarded after:
- writing all particular introductory tests - it forms 10% of classification,
- passing all practices and handing particular report till 10th day after the practise - it forms 35% of classification,
- passing self-measurement and handing final report in correct format at the latest in the credit week - it forms 15% of classification,
- successful passing the credit test (minimum score is 60%) - it forms 40% of classification.

13. Credit test

Aims

The aim is to observe and to deduce supramolecular structure of selected polymeric materisals from indirect methods and to demonstrate that final properties of polymer materials are done by supramolecular structure, which can be very easily changed, for example by heating and cooling rates of the melt. Very important part is identification of blank solid polymeric materials by selected method.

Specification of controlled education, way of implementation and compensation for absences

The attendance in all practices is demanded. In case of the absence, the practice can be compensated with another group or in the last week of the term. An unexcused absence is the reason for the loss of the credit.
Theoretical knowledge of students regarding the particular practice is examined by the written tests at the beginning of the practice (10-12 questions).
Laboratory report is demanded from each student after each class and handover according to the instructions of a teacher.
