Polymer nanomaterials and nanoprocesses in polymers
Raab, Miroslav
Polymeric nanomaterials and nanoprocesses in polymers. Polymeric nanomaterials have been attracting great interest both from scientific and technological points of view. The basic ways to nanomaterials with polymeric matrix are reviewed together with the methods for their structural characterization. These methods are suitable also for the study of nanoprocesses in polymers.
Structure and segmental dynamic as determinated by by solid-state NMR. Comparison with X-ray diffraction data
Brus, Jiří
3D structure and segmental dynamics of microcrystalline simavastatin were determined by multidimensional 13C CP/MAS NMR experiments at normal temperature.
Simple timing of MATLAB GUIs used in MS-Windows for data acquisition
Nesládek, P. ; Steinhart, Miloš
The contribution proposes an elegant possibility of timing in the basic MATLAB. The timer is a small program running in the Windows environment. Its function is to periodically click a pushbutton in a GUI by simulating an action of a mouse through sending on appropriate message into the Windows message queue. The timer can be used in cases when sampling or other action is to be done periodically in time points. These cases are e.g. data acquisition or periodical monitoring of some dangerous status of the controlled instruments.
Influence of the degree of sulfonation on transport properties of membranes based on poly(2,6-dimethyl-1,4-phenylene oxide)
Moravcová, S. ; Bímová, K. ; Bouzek, K. ; Schauer, Jan
Transport properties (protonic conductivity and ion exchange kinetics) of membranes based on sulfonated poly(2,6-dimethyl-1,4-phenylene oxide) were investigated. Diffusion coefficients for protons in the membranes sulfonated to various degrees were determined using the theory of absolute mobilities of ions.

Charge densities and topological analysis
Šlouf, Miroslav
Lecture compares conventional X-ray diffraction analysis on single crystals with more precise techniques based on kappa-refinement and multipole refinement. The results that can be obtained from precise charge denstity studies and topological analysis are listed. Examples taken from practice show how to calculate atomic charges, double-bond characters etc. from both experimental X-ray data and theoretical quantum chemistry calculations.
