Micro and macro mechanics

Based on its theoretical origins, the field of mechanics is a subcategory of physics. It also relies on mathematics to provide solutions for versatile challenges. Mechanics is considered as one of the foundational disciplines for engineering sciences. Familiarity with mechanics is required for every engineer to solve new problems in a constantly faster changing technological environment. Hence, mechanics is a “timeless” science.

The close link between mathematics and mechanics becomes evident in the research topics of the chair for Applied Mechanics and Fluid Dynamics. Macroscopic processes such as

  •     “subtle” flows with heat and mass exchange
  •     flow instabilities
  •     rheology of “dead” and biological dispersions
  •     mechanical behaviour of composites

can only be understood once microscopic processes such as

  •     flow structures
  •     interactions between structural elements
  •     mechanical properties of biological cells and cell composites

etc. have been understood. Such research is conducted at the chair using the most up-to-date measuring processes and methodologies as well as sound theoretical work.

Vorbild Natur_KopfbildBio-inspired high-performance materials

Many natural protein materials exhibit ideal properties for certain technical and biomedical applications. They inspire the development of innovative polymer materials with outstanding mechanical performance, bio-compatibility, biological degradability and the ability of functionalisation. The research activities of the Biomaterials chair focus on characterisation, functionalisation and biotechnical production of structural proteins as well as on processing methods for biopolymers to be used intechnical and medical applications.

The team investigates different biological model systems (such as spider and insect silk, or collagenous byssus threads of mussels) and analyses and produces peptides, proteins as well as hybrid materials. Molecular interactions and assembly mechanisms of the underlying peptides or proteins influence structural functions and material properties. The physical-chemical properties of mimetic, recombinantly produced proteins are characterised and processed.

An interdisciplinary team provides expertise in six working areas:

  •     Protein analytics
  •     Protein design
  •     Recombinant protein production (“white biotechnology”)
  •     Functionalisation and modification of proteins
  •     Process technology (spinning, casting, coating processes, microfluidics etc.)
  •     Cell biology

The range of applications covers fine dust-filter materials, speciality textiles, cosmetics, wound care, implant coatings, 3D tissue engineering (Biofabrication) and drug depot and delivery systems.

OFCHigh-performance ceramics, fibres, coatings and composites

The team of Ceramic Materials Engineering deals with application-oriented challenges in the field of functional and structural ceramics. They have years of experience in the materials and process development of powder and precursor ceramics as well as their characterisation.

Research is also focused on the technology of ceramic composites and on all aspects of engineering with this materials class.

New ceramic materials, process technologies and prototypical components are created in cooperation with partners from the industry. Fundamental research is carried out as part of international cooperation, too, e.g. with Brazil (research project “Development of abrasive-resistant and dry, self-lubricating coatings on sintered steel on the basis of polymer derived ceramics (PDCs)”).

Bild 7From the chemical lab to industrial production

Chemical engineering is the link connecting chemistry and engineering science. Chemical engineers enable the transfer of lab scale synthesis to industrial scale processes yielding to beneficial products such as fuels, polymers and pharmaceuticals as well as steel and concrete to name just a few. Furthermore, chemical engineers are also keen to developing new processes and optimising even mature operation units to make them more economic and sustainable. Here, the knowledge of chemists in e.g. synthesis of organic and inorganic compounds, catalysis and physical chemistry meets with the art of engineering like plant design, mass and heat transfer and mathematics/computer science (reactor and process modelling). Thus, fundamental understanding of the topics is required to reach these challenging tasks, which will become more and more important in the very near future.

However, since the sheer knowledge in both engineering and chemistry is nearly impossible to be amalgamated by only one subject, interdisciplinary work is crucial to understand and evaluate chemical processes from the chemical background to the basic data of industrial processes. Our team therefore consists of engineers as well as chemists and physicists.

Apart from optimising well-known chemical processes, new materials and processes are being tested and developed. Up-scaling parameters are also being determined to transfer reactions from lab size reactors to industrial plants. The pure scientific theory is always with us the basis of practical work and is only in its complement, a future-oriented connection. That makes the value of our work really important and encourages projects over long periods of time. The research fields include:

  • Reaction technology
  • Reaction kinetics and catalysis
  • Modelling and simulation of chemical reactions and processes
  • Chemistry and technology of gas, oil, coal and biomass
  • Fischer-Tropsch synthesis
  • Methanation reaction
  • Reactions and processes in petrochemistry
  • Synthesis of fine chemicals
  • Application of ionic liquids in catalysis (e.g. SCILL-catalyst) and separation technology

In our extensive research, analysis is always in the foreground. We are often asked by companies and industry as a scientific partner to research work in the fields mentioned above.

For example, in Fischer-Tropsch synthesis and methanation reaction we are trying to make them more efficient. For the both, we are strongly interested in applying synthesis gas containing CO2 to make use of the carbon dioxide as chemical feedstock compound, instead of releasing the gas into the atmosphere. Furthermore, we are trying to enhance the performance of catalysts by catalyst modification (i.e. synthesis and characterization of catalysts); by using XRD spectroscopy, changes in the catalyst’s bulk phase are observed to gain information on the active bulk phase keeping the catalyst alive. Finally, based on appropriate studies in the laboratory scale, the basic data are obtained that allow a scale-up to the industrial scale by modelling and simulation of the processes of interest.

01_AbgasnachbehandlungThe material itself as core of a component

Functional materials, in contrast to structural materials, are being used due to their special functional properties. That includes applications of optical, magnetic, electric, sensoric or catalytical properties. Especially the last three mentioned are being studied at the Department of Functional Materials.

We follow a comprehensive approach. The material itself is the core of the application. This work includes the complete process chain, from material to component. Our main research areas serve the following fields:

  •     Gas sensors for detecting harmful substances in the workplace and for ambient air monitoring
  •     Exhaust gas sensors and exhaust gas treatment in automotive and industrial atmospheres
  •     Ceramic micro system technology, ceramic multi-layer technology
  •     Biosensors for selective detection of analytics on the basis of enzymatic and electrochemical processes
  •     Materials for energy conversion.

Our team consists of engineers from materials science, environmental, biotechnology or electro technology, of natural scientists from chemistry or physical technology and of technical staff.

We have the most versatile technologies and methodologies at our disposal. For example, as part of the field of gas sensor technology, we can work on the complete process chain for the realisation of sensors and their characterisation.

Materials Processing

Polymerelektrolytmembran_KopfbildNew materials through creative process development

The chair for materials processing combines the fields of materials science and process technology with the objective of developing new material properties and multifunctional property profiles with optimal energy and ecological procedures by creating new synthesis and processing procedures for materials.

Based on a deep understanding of existing processes, creative linking of various energy sources and process types can develop new methods for formation, reformation, coating or material property changes which can already take into consideration the integration of various materials classes to one component or system.

In doing so, materials science concepts, such as anisotropic composites, function gradients, the inter-penetrating phase network or the hierarchical structures, play an important role.

The research in the field of materials processing focuses on the entire process chain - from the synthesis of the material and its processing to a component to specific system integration.

The system idea is provided by the focus on specific application ranges of materials and process development affecting new procedures for gas phases or solvent-based coating, for sintering, processing of materials relating to melts, colloid or electrochemical and electrothermal processes:

  •     Battery materials: active masses, electrodes, electrolytes
  •     Fuel cells and electrolyser materials: for polymer-based and ceramic systems
  •     Materials for thermochemical processes: Insulation layers, refractory products for glass melts
  •     Photovoltaics and photocatalysis: Glasses and transparent semi-conductors

The research of this chair is focused on the energy and propulsion technology with power electronics assuming a central role. Control and regulation meets actuating elements and sensor technology which then finds its connection to mechanics in propulsion technology.

Core of the work are the development of new circuit technology, the use of new components and a systematic optimisation:

  •     Electrical energy conversion with increased output density
  •     New components for power electronics
  •     Integration of energy storage systems
  •     Energy conversion in high-performance range
  •     Mechanical and thermo-mechanical fault mechanisms in electrical energy conversion

Polymers: Materials – Processing – Properties

The department of Polymer Engineering at the University of Bayreuth stands for scientific research with a practical orientation in the field of polymers. The main focus is set on material, processing and design. Aim-orientated analyses and the establishment of relationships between material, processing and properties are emphasized. This enables a strategic approach for the development of innovative products with modern polymers.

Processing of Thermoplastic Polymers

In the field of thermoplastic processing, modern compounders are available for a target orientated modification of polymers the department of Polymer Engineering. The selection of specific additives can optimize the mechanical and functional properties, like flame protection, barrier properties or transparency.

The available injection molding and extrusion plants allow a “step by step” optimization of the thermoplastic process chain from lab scale up to industry scale. In combination with an excellent analytic infrastructure in the field of rheology and thermal analysis correlations between material and process can be identified and optimized.

Polymer Foams

Foams are of high importance in light weight applications, innovative packaging as well as modern systems for insulation. Currently the department for Polymer Engineering deals with the incorporation of graphene in polymer foams to optimize the insulation properties. Focus is to investigate the influence of graphene on the foamability, morphology and heat conductivity.

Another innovative application for foams is the use of foamed, thermoplastic substrates for printed circuit boards (PCB). Thermoplastic substrates for PCBs with a foamed core and a compact top and bottom layer represent a novel and revolutionary concept with numerous advantages. The foamed core leads to excellent dielectrical properties and a weight reduction.

Fiber Reinforced Polymers

In the field of fiber reinforced polymers, the department intensively works on the development new and tailored thermoset matrix systems. Aspects like toughening, flame protection as well as rheology and cure kinetics are emphasized in the research activities. Endless fiber reinforced laminates with thermoset matrices can be produced with the injection plant of the department by resin transfer molding. For the characterization of the mechanical properties of these materials, the testing center of the department disposes of nearly all state of the art testing methods for static and dynamic composite tests.

Besides the scientific and technical facilities at the campus of the university the department of Polymer Engineering has further premises and equipment at the cooperation partner Neue Materialien Bayreuth GmbH. The division Polymer Engineering of the TuTech Innovation GmbH in Hamburg is a link to the industry in northern Germany.

Process Biotechnology
Einklappen

zellenBiopharmaceuticals, Bioreactors, Biological systems in a technical environment

Bioprocess technology represents a key discipline in modern process technology. It covers a wide range of implementations, where  biological components or concepts are used for production and services provision. In bioprocess technology, interdisciplinary teams of engineers and scientists develop processes, which range from medical technology (tissue engineering, implants) and the production of insulin and other biopharmaceuticals to the use of technical enzymes as catalysts in the chemical industry or that of microorganisms in the production of renewable energy (biogas, biological fuel cell).

Research at the Chair of Process Biotechnology focuses on the development and intensification of bioproduction processes often at the interface to the material sciences. This includes the genetic modification and controlled manipulation of mammalian cells for the production of pharmaceutically relevant proteins such as growth factors and antibodies. Other focal areas are the ex vivo expansion and controlled differentiation of human blood cells. Biomimetic materials, bioconjugates as well as their interactions with cell surface markers and proteins play an important role in these studies.

Interests in microbial systems include the study of microbial consortia (population and metabolism studies) in technical systems (biogas plant, bio fuel cell) as well as the production and optimisation of technical enzymes for biosensors or biotransformations. Here the focus lies on the development of the entire bioprocess and its integration into existing industrial processing schemes. A very recent development in the group are the “artificial biofilms” intended for process intensification, i.e. biocomposites containing the biologically active component in a fully synthetic, functionalized hydrogel matrix.  Our work benefits from an outstanding infrastructure in mammalian cells culture, technical microbiology, as well as bioanalytics and peptide synthesis.
