  3. Ceramic bioreactors for biomedical applications

    A growing number of bioceramic materials are applied in tissue engineering of three-dimensional (3D) scaffolds. Ideally, 3D scaffolds should be highly porous, have well-interconnected pore networks, and have consistent and adequate pore size for cell migration and infiltration. Scaffold architecture design can significantly influence both mechanical properties and cell behavior. However, chemical and phase composition are critical for bioactivity and chemical reactions in bioreactors. Aim of this Ph.D. study is to prepare ceramic bioreactors with various shape, chemical and phase compositions. Mainly the bioactive calcium phosphate materials will be shaped to the desired structure and combined with other materials to prepare bioreactors suitable for regenerative medicine. The research will require a multidisciplinary approach and cooperation with CEITEC BUT partners.

  4. Ceramic materials and composites for advanced applications

    Recently, a worldwide trend is the development of new types of ceramic materials with a suitable combination of useful mechanical, biological, optical or electrical properties which are used in in advanced applications. For the preparation of such materials, critical consideration of the final structure at the design stage is required as well as the correct selection of input powder materials, the choice of advanced forming techniques and optimised sintering process conditions. The aim of the dissertation work will be to prepare single-phase and multi-phase ceramic materials using modern technological processes such as dry and wet shaping methods, additive technologies, spark plasma sintering, etc., and evaluation of their properties with respect to their specific application.

    With the ultrasonic loading machine, billions of load cycles can be achieved in a relatively short time. Thus cracks occur even under loads below the conventional fatigue limit.

  8. Cyclic plasticity and microstructural changes in fatigued ultrafine-grained austenitic stainless steels prepared by reversion annealing

    Advanced ultrafine-grained (UFG) materials with a mean grain size smaller than 1μm have attracted the attention of research community due to their highly enhanced mechanical properties. Grain size refinement of metals via severe plastic deformation (SPD) is in the centre of research for several decades. It was repeatedly demonstrated that various SPD methods, ussually equal-channel angular pressing (ECAP) or high pressure torsion (HPT), are feasible to produce “bulk” ultrafine-grained (UFG) materials with considerably enhanced mechanical properties. The SPD grain refinement generally results in an improvement of strength characteristics under monotonic and high-cycle fatigue loading conditions. Due to low ductility and mechanical and thermal instability of UFG structure it has also a detrimental effect on fatigue characteristics obtained during strain controlled, i.e. low-cycle fatigue (LCF) tests. In case of metastable austenitic steels an alternative and very promising technique of grain refinement and thus strengthening represents the so called reversion annealing. This special thermomechanical treatment is based on the phase transformation of strain induced martensite created during cold working back to austenite. Depending on the conditions of thermomechanical treatment the UFG structure can be achieved with supposed effect of strength enhancement while retaining the excellent ductility of the resulting material. Positive effect of grain refinement using this thermomechanical treatment on high-cycle fatigue (HCF) behavior has been documented for several types of metastable austenitic steels. Although LCF behavior of this steel is of great importance for potential industrial and medical applications, it has not been studied systematically so far. The principal goal of the proposed study is thorough experimental study of cyclic plasticity and low-cycle fatigue (LCF) behaviour of metastable 301LN austenitic stainless steel with grain sizes ranging from several hundreds of nanometers to several micrometers. The grain refinement will be achieved by proper choice of conditions of reversion annealing (temperature and time) after prior cold deformation. Fully symmetrical LCF tests will be conducted on flat sheet specimens at room temperature with low constant strain rate. The cyclic stress-strain response (cyclic hardening/softening curves) in the wide range of constant total strain amplitudes and fatigue life curves will evaluated for all grain sizes. Microstructural changes, fatigue damage mechanisms and destabilization of originally fully austenitic structure will be characterized after cyclic straining by ferritescopy and advanced microscopic methods (SEM-FEG, EBSD, FIB). To reveal the finest details of deformation mechanisms TEM technique will be adopted. Experimental data on microstructural changes in grain-refined steels will be used to discuss and interpret the cyclic stress-strain response and fatigue life for all grain sizes with the aim to reveal an effect of grain refinement on LCF behavior of metastable austenitic steels

  9. Development of piezoelectric lead-free ceramics for energy harvesting

    Recently, energy harvesting based on piezoelectric ceramics has attracted wide attention as an electric energy source for low-power electronics. Due to environmental aspects the commonly available piezoceramic generators based on PZT (Pb-Zr-Ti-O) must be replaced by lead-free materials. BCZT (Ba-Ca-Zr-Ti-O) a BT (BiFeO3) are very promising lead-free piezoelectric ceramic materials for this application. The work will be, therefore, focused on the development and study of these unleaded materials and their controlled doping for the purpose of efficient electric energy harvesting. The student will develop processes for preparation of piezoceramic and composite piezoceramic tapes for application in energy harvesters. The efficiency of the new materials in the energy harvesting will be evaluated. Internship at the University of Oulu is planned during the study.

The dielectric capacitors allows fast charging and discharging compared to lithium-ion batteries, moreover, these materials have a higher cyclic life. The ceramic-ceramic or ceramic-polymer composites seem to be the ideal candidates. The aim of this Ph.D. study is to increase the energy density characteristics through modulation of the nanostructure in 3D (the formation of a texture) what is necessary for the mobile applications of these dielectric capacitors of new generation. The innovative processing techniques such as Spark Plasma Sintering and Freeze-casting will be applied to achieve tailored microstructures of the investigated materials.

  12. Effect of entropy in impurity segregation at grain boundaries

    Despite of evident significance of entropy in various phenomena of materials science, this quantity is neglected in their quantification in majority of cases. This negligence results in inaccurate quantitative values and – in the case of generalization – in incorrect prediction and interpretation of the effects. The aim of this work is to demonstrate the role of the entropy for an important example of solute segregation at grain boundaries of bcc iron. Practical methods of theoretical determination of the entropy of segregation will be developed and the data calculated for selected solutes will be compared to experimental values in literature. The calculated data will be then tested using known phenomena, such as the anisotropy of the grain boundary segregation and enthalpy–entropy compensation effect.

    Tutor: Klusák Jan, doc. Ing., Ph.D.

  16. Friction materials – analysis of their composition and degradation

    Modern friction materials used in transportation are complex composites with sophisticated structure and chemical composition. The reason for this complexity is the wealth of physical and chemical processes occurring in the braking system. One of the most critical aspect is the degradation of friction materials during the braking and subsequent release of small particles into the environment. A detailed study of these particles is of utmost importance as they significantly contribute to the pollution of the predominantly urban environment. First, they cause the pollution of the soil in the vicinity of main roads. Second, our inhalation of these particles is known to be very dangerous to our health. The aim of proposed PhD program is to determine the impact of various degradation mechanisms in friction materials (heat, environ-ment and salty solutions), materials characterization of friction materials as well as thorough analysis of particles released during the braking.

  18. Hydrogen storage in metallic materials with varied phase and chemical composition

    Hydrogen is a very prospective and eco-friendly fuel which can bring significant economical and environmental benefits. The main obstacle that impedes expected future of hydrogen technology is safe and acceptably efficient hydrogen storage (HS). It is generally accepted that a possible solution to this problem is HS in solid phase of metallic materials (HSM). However, there are not HSMs up to now with sufficient HS properties at low temperature and pressure. Therefore, the main idea of this study is to investigate HS properties of new perspective model alloys which could show effective HS at temperatures near to room temperature and at low pressure. One of ways how to influence HS properties HSM is to change their phase and chemical composition. The results could lead to new strategies in development of HSM.

  19. Hydrogen storage in Mg-based materials with various level of crystallinity

    Hydrogen is a very prospective and eco-friendly fuel which can bring significant economical and environmental benefits. The main obstacle that impedes expected future of hydrogen technology is safe and efficient hydrogen storage (HS). It is generally accepted that a possible solution to this problem is HS in solid phase of metallic materials (HSM). However, there are not HSMs with sufficient HS properties at low temperature and pressure. Therefore, decreasing the thermodynamic stability of hydride phase of HSM with high hydrogen capacity is crucial for tuning their HS properties. One of ways how to influence thermodynamic properties is changing of structure states and chemical composition of HSM. The main idea of this study is to investigate the HS properties of model Mg-alloys in various states of structure from critically cooled or amorphous state to ordered crystallized structure. These materials could show desired HS properties at lower temperatures and pressures. The results could indicate new ways for development of new HSM.

State of the art additive fabrication technologies are unable to produce auxetic structures with engineering properties effectively. Another fundamental scientific challenge is merger of structural properties and autonomous mechano-adaptability. The aim of this project is to discover fundamental principles governing formation of structural architecture exhibiting auxetic behaviour employing functional nano composites of block copolymers with shape memory functionality controlled by light stimuli.

  24. Magnetic properties of high-entropy alloys

    So-called high-entropy alloys represent one of the most promising classes of modern materials. They are characterized by specific atomic distributions when a number of chemical species randomly occupy crystalline lattice positions. Combination of different elements and their concentrations provide materials with a wide range of unique properties. After years of intensive research focused on mechanical properties of high entropy alloys, the international scientific community has become recently interested in their magnetic properties.

  27. Microstructural stability of wrought austenitic stainless steels: Impact of local chemistry

    Within a stainless steel family comprising five basic types the wrought Cr–Ni austenitic stainless steels (AISI 300 grade) still occupy a privileged position. Due to their exceptional corrosion resistance and prominent mechanical and technological properties have found utilization in diverse industrial, domestic, architectonic and biological applications at room and elevated but also at cryogenic temperatures. The f.c.c. (face centered cubic) paramagnetic austenitic  structure of most of these alloys is known to be, however, metastable, i.e. it can partially transform to ferromagnetic b.c.c. (body centered cubic) ′-martensite during cooling and/or plastic straining. The most important parameters controlling the stability of austenite are chemical composition and temperature. The formation of ′-martensite can have a beneficial effect on mechanical properties of these steels but with respect to the corrosion resistance of these steels the presence of ′-martensite may be detrimental and in the case of some applications (e.g. superconducting magnets) must be avoided. In the absolute majority of studies dealing with the stability of wrought AISI 300 grade austenitic stainless steels so far these materials are considered to be chemically homogeneous after numerous step of hot working. The importance of local chemistry in the form of chemical banding on the destabilization in various semi-product forms of wrought AISI 304 grade steels has been recognized only recently (J. Man et al.: Effect of metallurgical variables on the austenite stability in fatigued AISI 304 type steels. Eng. Fract. Mech. 185 (2017) 139–159). The principal goal of the proposed study is thorough experimental study of destabilization of austenitic structure and DIM (deformation induced ′-martensite) formation in wrought AISI 300 grade ASSs in the perspective of their physical metallurgy. The great importance will be put on the description of characteristic forms of local chemistry in various forms of steel semi-products and their impact on the morphology and spatial distribution of DIM in the whole volume of strained selected ASSs (304/304L, 316/316L, 321, 301LN). The experimental program will accomplish the following topics: (i) systematic monitoring of chemical homogeneity of AISI 300 series austenitic stainless steels (304, 316 and some others) in various industrially produced wrought forms (cylindrical bars, thick and thin plates), (ii) systematic study of destabilization of wrought 316-type ASSs of various semi-products under cyclic straining under total strain control at room and especially depressed temperatures. (iii) Qualitative and quantitative study of DIM formation during tensile testing of 304- and 316-type ASSs at room, depressed and elevated temperatures with the particular emphasis on the spatial distribution of DIM across the sheet thickness and iv) Experimental study of local chemistry and texture on austenite destabilization in ultrafine-grained AISI 301LN steels produced via reversion annealing after prior cold deformation. The chemical heterogeneity across the whole cross-section of various semi-product forms will be characterized qualitatively by color metallography and quantitatively by EDS technique. Volume fraction of DIM will be evaluated across the sheet thickness using X-ray technique and compared with Ferritescope data. Microstructure of deformed specimens and especially the DIM distribution across the sheet thickness will be visualized using color technique (Beraha II) and for detail characterization of DIM morphology at the microscale modern high-resolution techniques SEM–FEG, ECCI, EBSD and TEM will be adopted. The local texture analysis of ultrafine-grained steels will be performed in co-operation with CEITEC Brno University of Technology or TU Bergakademie Freiberg/Germany.

In addition to chemical-physical characterization, the hydrogels will also undergo enzymatic degradation and biological monitoring of biocompatibility in vitro.

    Tutor: Macák Jan, Dr. Ing.

  31. Non-linear mechanical response of self-assembled polymer nanocomposites

    A key obstacle in the development of complex multiscale theories lies in our current inability to directly control the structure formation at multiple hierarchically arranged length scales. Directed self-assembly of surface decorated precisely defined NPs represents means for obtaining precisely controlled spatial arrangements of NPs. No theoretical framework has been published describing the laws governing multi length scale assembly of NPs into hierarchical superstructures in polymer continua. We aim at developing experimental and theoretical foundations for novel multiscale hierarchical predictive model of relationships between structural variables, nature and kinetics of the structural hierarchy formation via self-assembly of NSBBs and the physico-chemical and mechanical properties and functions in polymer nanocomposites.

  36. Structure of magnetic materials at low temperatures

    Our thorough understanding of magnetic properties is intricately inter-linked with a detailed information about the structure of studied materials. The decreasing particle size and/or temperature resulted in the past few years to the observation of new magnetic states, for example, the superparamagnetism. Importantly, the magnetic states sensitively depend on the atomic structure, crystal boundaries and/or magnetic domains which all significantly change with the temperature. The proposed PhD study will therefore focus on these structure-property relations at low temperatures. The following aspects will be covered: - Preparation of samples by various methods - Structural study of materials by XRD, SEM, TEM, AFM etc. - Magnetic measurements by VSM, PPMS and SQUID

    The main aim of this work is to prepare “smart” hydrogel substrates that are able to react to pH or temperature and are suitable for 2D and 3D cell monitoring in molecular biology or tissue engineering, or for testing new drugs on cancer cells. Hydrogels should be suitable for both in vitro and in vivo applications. In addition to chemical-physical characterization, hydrogels will be subjected to biodegradation and monitoring of biocompatibility in vitro.
