Use of empirical force fields to describe structures of hybrid organic-inorganic materials. Prediction of their properties based on a combination of modelling and experimental data (XRD, TEM, chemical analysis, thermogravimetry and IR spectroscopy). Applications for molecules, polymers, solutions of crystals and supramolecular materials. Applications for description of solid phase processes - intercalations, sorption, interface of the phases and surfaces. Studying structures of polymeric networks and liquid crystals. Study of molecule conformations and relation to biological activity.

The gain of the credit is a prerequisite for the examination.

The credit is bound to the credit computational task, it is assumed that there will be correction deadlines for the credit test and the exam.

Lecture (2 hours) and practical seminar (1 hour).

Requirements to the exam -
Last update: doc. RNDr. Miroslav Pospíšil, Ph.D. (27.04.2023)

The exam consists of written preparation and oral part. Written preparation precedes the oral part. The student receives three questions, each question is evaluated by a mark, and the resulting mark is the average mark of the marks on the individual questions. If one of the questions is rated as unsatisfactory it means failure to complete the test. Failure to pass the exam means that three questions will be asked again at the next term of exam.

Requirements at the oral part of the exam correspond to the syllabus of the subject in the scope that was presented at the lecture.

It is probable that a significant part of exams or credits can take place in a distance form. It depends on the development of the current situation and you will be informed about any changes in time.
