Research groups at department of Chemical Engineering

Here is a brief overview of the research groups, contacts for responsible persons can be found here.

Laboratory of Bioengineering and Functional Materials

(Assoc Prof. Šóoš, Dr. Hassouna, Dr. Skořepová)

Bioengineering and functional materials engineering focuses on the development and production of materials with high added value, often requiring knowledge from different areas of knowledge from nano-level interactions to macroscopic scale at the level of the manufacturing apparatus. Understanding these phenomena enables the development of new or optimization of existing processes for the production of future materials. The whole process can be divided into the following phases: 1) preparation and modification of building units (nanoparticles, nanocrystals and nanodroplets), 2) creation of hierarchical structures from nanoparticles, 3) characterization of materials 4) modeling of control mechanisms 5) application of functional materials for delivery of drugs, Tissue engineering, packaging, automotive, etc. Web »

Laboratory of Chemical Robotics

(Prof. Štěpánek, Dr. Grof, Dr. Zadražil, Dr. Čejková, Dr. Hanuš)

Our research is focused on the design and synthesis of structured particles and particle systems in two main areas – in “traditional” Particle Technology (granulation, spray drying, encapsulation, fluid bed processing, and dissolution) and in the emerging field of Chemical Robotics. Our aim is to conceive microscopic chemical robots that mimic single-cell organisms in that they are capable of autonomous movement (chemotaxis), they have the ability to store, chemically process and release molecules on demand, and they can recognize the target by specific adhesion. Unlike living organism, they cannot evolve or self-replicate, but they can be remotely controlled – thus the name “robots”. Further we focus on Pharmaceutical Engineering, where our aim is namely to understand the process-structure-property relationships for solid dosage forms such as tablets, and to use this understanding for the rational design of new products and manufacturing processes. The engineering of pharmaceutical products and associated manufacturing processes poses a challenge for chemical engineering due to the complex nature of the materials, both in terms of physico-chemical properties (e.g. amorphs, far-form-equilibrium mixtures, etc.) and in terms of process equipment and scale-up (e.g. multiphase and solids flow). Examples of our projects include the use of naturally sourced particles as drug carriers (yeast glucan particles), development of nano-structured carriers for cancer theranostics, use of 3D printing for the manufacture of personalised medicines, and the development of new approaches in the fight against antibiotic-resistant bacteria. We also develop new computer simulation tools of particle-based processes. Web »

Laboratory of Polymer Engineering, Energy Storage and Nanotechnology

(Prof. Kosek, Dr. Zubov, Dr. Pocedič, Dr. Mazúr)

The research activities of the group cover experimentally and theoretically a broad field of current chemical-engineering themes. In the field of polymers, we study the morphology depending on the conditions in industrial reactors, the development of hi-tech insulation materials and the measurement of basic transport variables. We have rich industrial and academic cooperation in this area. The second major research topic is the storage of energy in stationary flow storage and supercapacitors and its recovery in mobile fuel cells, in particular for metallic fuel. We also deal with the preparation and application of nanoparticles, especially of transition metal oxides in third generation solar cells, batteries, photolysis of water and other energy use. All of these topics are studied experimentally, also using mathematical modeling. Web »

 

Laboratory of Fire Engineering

(Assoc. Prof. Jahoda)

The main aim of the Laboratory of Fire Engineering is the active use of methods of computational fluid dynamics (CFD) in resolving the problems of burning, fires spreading and extinguishing of fires. Areas related to the dynamics of combustion are also studied, for example the kinetics of thermal decomposition of solids, the rate of evaporation of volatile liquids during combustion, rate of spread of flammable gas leakage from storage tanks. For calculations the special CFD programs are used (Fire Dynamics Simulator (FDS), FireFOAM and ANSYS Fluent). Computational methods are complemented by experiments in laboratory-scale. The research group collaborates with the Technical Institute of Fire Protection in Prague on research projects and implementation of large-scale fire tests. Web »

 

Process and System Engineering Laboratory

(Assoc. prof. Moucha, Dr. Linek, Dr. Vaněk, Dr. Rejl, Dr. Valenz, Dr. Haidl)

In the group, apart from basic research and pedagogic activities, large attention is devoted to industrial research. Present day issues of industrial process units are approached via process simulation or direct experiments. Our interest is focused on gas (or vapour) - liquid mass transfer processes. In this field, our group has rich experience and extensive database of our own experimental data. Apparatuses of laboratory and pilot-scale are at disposal. Apparatuses available for the fundamental research include apparatuses for studying of mass transfer mechanisms (processes at the interface) such as agitated tank with calm liquid surface, agitated tank with gas-liquid dispersion, wetted wall column and other necessary equipment, which help determining equilibrium and kinetic data for reliable design of industrial columns even for systems with not well defined physical properties. For the industrial research, available apparatuses include an absorption column up to 0.4m in diameter, multiphase agitated tanks up to 0.6 m in diameter, bubble column with ejector gas distributor with 0.4 m in diameter and distillation column of 0.4 m diameter.

Laboratory of Biomimetic Engineering

(Dr.Tokárová, Dr. Kašpar)

The Laboratory of Biomimetic Engineering was established in 2017 as a research group at the Department of Chemical Engineering. Our aim is to study, understand and improve natural solutions and designs in a way to solve problems of modern society - biomimetic. Numerous inventions around us were initially inspired by living matter (microorganisms, plants or animals). Some famous examples are Velcro stripes inspired by the structure of burrs, self-cleaning surface mimicking hierarchical topology of lotus leaf or artificial neural networks inspired by a brain structure. Biomimetic is more than ever successfully applied in the fields of material sciences – smart materials, fluid flow – drag reduction, target drug delivery and natural “antibiotics”. The main research areas of the group are focused on controlled synthesis of nanoparticulate systems using microfluidics, development of composite microparticles for antibacterial applications, surface modification, particle-cell interactions, CFD simulations of multiphase flow, capillarity and wetting phenomena on structured surfaces.
