Departmental seminar on 7th December 2022

This week we have a guest, Ing. Pavel Izák, Ph.D., DSc., from the Institute of Chemical Process Fundamentals, Czech Academy of Sciences. His talk is called The potential of membrane separation processes in gas and liquid mixture separation.

The talk will summarize results and also the potential of separation of gas and liquids through nonporous membranes. Two membranes separation techniques are involved, namely the pervaporation and the gas separation. Special attention is focused on ionic liquids, which have a growing potential in both previously mentioned techniques. Nowadays the separation of various gaseous and also enantiomers from racemic mixtures have been within the gradually growing interest of many companies and research teams. Furthermore, the new kind of membranes can help improve separation and permeation properties. The scale up of purification of raw biogas to CNG from laboratory to pilot plant will be discussed.

The lecture will take place in person, in the hall CH3, Faculty of Science, Hlavova 8, Praha 2.

Departmental seminar on 2nd November 2022

This week we have a guest, Doc. Mgr. Martin Hrubý, PhD, from the Institute of Macromolecular Chemistry, Czech Academy of Sciences. He will speak about Supramolecular stimuli-responsive polymer
systems for theranostic applications
.

Self-assembly of molecules into complex supramolecular units with qualitatively new properties is in the chemical foundations of life and is the essence of the ability of living organisms to react to the external environment - irritability. Classical examples of such supramolecular structures are the cytoplasmic membrane formed by phospholipids, nucleic acids or multienzyme complexes formed by several enzymes catalysing  subsequent reactions on a single substrate. Understanding these mechanisms enables targeted chemical synthesis of analogous systems based on tailored polymers not only for biomedical applications.
A specific case occurs when the hydrophobic part of the molecule, or the part of the molecule responsible for self-assembly significantly changes its physico-chemical properties, such as solubility in water, by the action  of an external stimulus (changing temperature, pH, etc.). Then the self-assembly of such a system is controlled by this external stimulus and we are talking about systems sensitive to external stimuli. It is a certain, albeit much simpler variant of one of the life-defining qualities - irritability. Several such systems designed for biomedical applications will be presented in the lecture.

The lecture will take place in person, in the hall CH3, Faculty of Science, Hlavova 8, Praha 2.

Departmental seminar on 26th October 2022

This time we have a guest, Prof. Dr. Joachim Sauer, from Humboldt University of Berlin. The topic of his lecture is Ab Initio Free Energy Predictions with Chemical Accuracy: Adsorption and Catalysis in Nanoporous Materials.

The rational design of improved nanoporous materials requires the reliable prediction of rate and equilibrium constants, i.e. free energies, for elementary reactions and adsorption/desorption steps with no other input than the atomic positions. For realistic molecule-surface interaction models with hundreds of atoms in the simulation cell, with an accuracy that is comparable to experiment, this is a challenging problem of computational quantum chemistry. A general ab initio divide-and-conquer approach that uses (i) hybrid high-level QM (reaction site): low level QM (periodic solid) energies for stationary points and (ii) anharmonic partition functions for local sampling of the potential energy surface, will be presented. With this model a chemical accuracy (±4 kJ/mol) is reached for elementary reaction steps in zeolites and for adsorption in zeolites and MOFs.

The lecture will take place in person, in the hall CH3, Faculty of Science, Hlavova 8, Praha 2.

An informal discussion with the speaker on general topics of todays science will follow in the seminar room of the department (304F) over a cup of tea/coffee. All interested participants are welcome.

Departmental seminar on 19th October 2022

This time we have a guest, Doc. Daniel Jirák, Ph.D. from the Department of Diagnostic and Interventional Radiology, MR Unit, Institute for Clinical and Experimental Medicine. The topic of his lecture is Magnetic resonance imaging: its possibilities.

The aim of the lecture is to show the possibilities of magnetic resonance imaging, not only anatomical 1H MR imaging, but also the use of other isotopes (19F, 23Na, 31P, 11B). It will show possible applications with an emphasis on in vivo experiments and monitoring of transplanted cells labeled with different types of contrast agents in clinical and experimental medicine.

The lecture will take place in person, in the hall CH3, Faculty of Science, Hlavova 8, Praha 2.

Departmental seminar and Habilitation lecture of Dr. Mariya Shamzhy

We would like to invite you for a seminar and a habilitation lecture of Dr. Mariya Shamzhy.

The topic of her lecture will be Isomorphous substitution for the design of heterogeneous catalysts.

As one of the most important heterogeneous catalysts, zeolites found application in a number of large-scale processes that require active sites of different nature. Isomorphous substitution is a key way to tailor the characteristics of a zeolite for a particular type of transformation.
This habilitation lecture will introduce the phenomenon of isomorphous substitution while emphasizing its importance in the design of heterogeneous catalysts with specific properties of active sites. Particular attention will be paid to the contribution of the applicant in developing methods for control over the nature of acid centers in extra-large pore and hierarchical zeolites.

The lecture will take place in person, in the hall CH3, Faculty of Science, Hlavova 8, Praha 2.

Departmental seminar on 25th May 2022

This time we have a guest, RNDr. Zdeněk Lánský, Ph.D. from Institute of Biotechnology, Biocev, Czech Academy of Sciences. The topic of his lecture is Reconstituting cytoskeleton - one molecule at a time.

Cytoskeletal proteins drive cellular motion for example during cell division or morphogenesis. Ensembles of cytoskeletal proteins self-assemble to drive these processes. We are interested in the roles of the individual cooperating proteins and the principles that underpin their collective action.

We use single molecule imaging and manipulation techniques to quantitatively describe these biological systems. I will discuss two recent projects from the lab, covering the role of cross-linking proteins in actin contractility and the role of the neurodegeneration-related protein tau in regulating access to microtubules.

 

The seminar will take place in the lecture hall CH3 in person.

The online option remains available only on special request (e.g., for colleagues who are ill/injured or have any other important reason for which they cannot come).

Departmental seminar on 4nd May 2022

This time we have a public habilitation lecture of RNDr. Peter Košovan, Ph.D.. The topic of his lecture is Acid-base equilibria at the nanoscale .

Acid-base equilibria are ubiquitous in Chemistry, both in everyday routine work and in research. They are taught in secondary-school courses of Chemistry and then again later, in undergraduate courses of General Chemistry, Analytical Chemistry and Physical Chemistry. The basic concepts of acid, base, pH and the degree of ionisation are well established and familiar to every chemist. Nevertheless, a lot of confusion appears when these concepts are applied to complex systems at the nanoscale, such as solutions of polyelectrolytes, polyampholytes, charged biomacromolecules, self-organized polymer nanostructures, polymers at interfaces or two-phase systems containing macromolecules or supramolecular aggregates.

In this lecture, we will present a selection of results of our research, bridging the gap between simulations and experimental investigations of acid-base equilibria in macromolecular systems. The lessons learned from these results provide important clues on how the acid-base properties of complex fluids differ from the established picture described in textbooks.

 

The seminar will take place in the lecture hall CH3 in person.

The online option remains available only on special request (e.g., for colleagues who are ill/injured or have any other important reason for which they cannot come).
