| Project leader: |
RNDr. Kovaľ Vladimír DrSc. |
| Annotation: | The proposed project is devoted to the research and development of novel relaxor-type ferroelectric ceramics.
Relaxor ferroelectrics (RFEs) are receiving considerable attention from materials scientists due to their unique
properties for energy storage applications. However, dielectric capacitors made of RFEs, although presenting
faster charging/discharging rates and better stability compared with supercapacitors or batteries, are limited in
applications due to their relatively low energy density.
The main goal of the project is to design and prepare a lead-free RFE ceramic material with high energy storage
density and efficiency. A series of structural modifications using cationic substitution on a RFE material will be
carried out to enhance the energy storage capabilities of the ceramics. The effect of the chemical substitution on
ferroelectric phase transitions and formation of polar nanoregions will be investigated in relation to the
compositional disorder and stability of antiferroelectric state. |

| Annotation: | The project focuses on the research and development of calcium phosphate cement/starch/vitamin K composites with optimized composition. The aim is to achieve higher mechanical strength that remains stable even after soaking in body fluids. At the same time, the release of vitamin K should significantly contribute to the mineralization and regeneration of bone tissue. The project will study the release of vitamin K from phospholipid vesicles embedded in a composite cement paste based on tetracalcium phosphate/starch. It will also analyze the relationship between particle character and the final properties of biocements, which are crucial for their use in regenerative and reconstructive medicine. |

doc. RNDr. Lofaj František DrSc. |
| Annotation: | After introducing the high entropy stabilized alloys and ceramics, research focused on bulk multicomponent borides and carbides of the transition metals (TM) forming single-phase compounds. Since 2014, these activities expanded also in bulk two-phase fcc+hexagonal/bcc (e.g. TM boride +TM carbide) or even multi-phase ceramics with improved properties. However, analogous two-phase boride-carbide coatings have been produced up to now neither by conventional DC magnetron sputtering nor by more advanced methods, including High Target Utilization Sputtering (HiTUS). Therefore, the aim of the current project is the investigation of of the formation of two/multi-phase boride-carbide structures stabilized by high entropy in the multielement ceramic coatings based on transition metals using reactive HiTUS. At first, the depositions of single-phase TM borides and carbides will be investigated during rHiTUS. In the second stage, both processes will occur within one step. It allows us to consider the peculiarities of oech process and find out corresponding ways to control the formation of structure of the dual/multi-phase ceramic coatings. The novelty of the project is that it widens the existing bulk two-phase ceramic materials into the field of PVD coatings and brings new ways to control their design and properties via the application of a novel HiTUS technology. |

| Annotation: | Thematically, the main objective of the proposed project “CAFIHEC” is focusing on the development - processing, characterization, and testing – of new dual-phase high-entropy ultra-high temperature ceramic-based composites reinforced by carbon fibers with an overall aim to develop extremely hard and significantly improved, damage tolerant composites.
This new dual-phase HECs provide an excellent platform for controlling physical, thermal, fracture–mechanical, tribological, oxidation, and other properties of the system via microstructural engineering, e.g., by changing the volume fraction, size, and shape of each phase, in addition to tailoring the interfaces. These characteristics allow the materials to withstand extreme environments for potential applications in leading-edge industries such as hypersonic vehicles, and nuclear reactors. This research follows up on the latest world trends, in which Dr. Naughton-Duszova et al. have been published, as described in the State-of-the-Art in chapter 1.2.
Intensive investigations on HE-UHTC's in the past five years focused mainly on the modeling, processing, and characterization of their microstructure and mainly the basic mechanical properties such as hardness, modulus, and indentation fracture resistance using indentation methods have been studied. A very promising group of these advanced materials developed as potential systems for ultra-high temperature applications is the so-called dual-phase high-entropy ultra-high temperature ceramics (DPHE-UHTCs).

| Project leader: |
Ing. Falat Ladislav PhD. |
| Annotation: | The present project is focused on the development of universal burner design modifications for indirect heating by radiation tubes operating in vacuum mode, which is capable of adaptation to the time and technically conditioned decarbonization rate, i.e. gradual increase of the hydrogen content in the gaseous mixture of fossil fuel, which can reflect the production conditions, especially the required heat input and minimize the production of CO and NOx emissions and thermal stress due to different combustion characteristics of the basic combustible gases. The starting point for burner design modifications is a mathematical model of the hydrodynamics of mixing and kinetics of combustion of the CH4-H2 fuel mixture with hydrogen content in defined intervals. The actual design of the structural modifications of the current burners consists in the construction of a variable nozzle at the burner orifice. This is a set of nozzles for the supply of combustion air and fuel. An important part of the design of the nozzle and burner mouth design will be CFD simulations, which will be compared and verified based on measurements on the constructed physical model in the burner-radiation tube-cooling chamber system. The submitted project includes a comprehensive material analysis of the burner materials, welded joints and bends of the radiation tube exposed to thermal and hydrogen exposure to evaluate different types of material degradation (thermal embrittlement, hydrogen damage). The originality lies in the development of versatile burner designs for indirect heating capable of adaptively adapting to combustion conditions while changing the composition of the natural gas and maintaining the heat input. Universal design modifications will thus support the idea of circular economy. The output of the project will be a utility model application, and scientific articles and teaching materials for the design, development and structural modification of burners for indirect heating. |

| Annotation: | The project will address the issue of the use of methods and procedures for the modification of cutting tools for wood processing in forestry. The result will be an increase in their lifetime and a reduction in emissions and energy consumption of forestry machinery and equipment. The main objects of research will be tools for primary wood processing, modification and processing of forestry biomass for energy purposes, such as splitting and chipping tools, tools for cross-cutting wood, etc. The main task of the project will be the design of procedures and methods for the modification of exposed functional surfaces of the tools. Ensuring a higher quality of functional tool surfaces in the context of reducing friction and eliminating adhesion, provides a prerequisite for reducing the load on machinery equipment and thus reducing emissions and energy consumption in a given production. Analyses will be carried out on the tools - FEM analysis in order to determine the stress-strain state, on the samples analysis of the state of the material in terms of physical properties, microstructure, mechanical properties and resistance to adhesive wear in wood-metal interaction and also abrasive wear. Based on the results of the analyses carried out, innovative surface treatment procedures will be proposed
for the exposed functional surfaces to guarantee an increase in their functional lifetime. These will be applied to samples and laboratory tested by relevant test procedures. From the results of the laboratory tests, a selection will be made of the most appropriate non-conventional innovative procedures, which will be applied to the tools and tested on the equipment under forestry operating conditions. In doing so, it will be observed how the modifications in question affect the energy consumption of forestry machinery and equipment. Part of the project solution will be to ensure industrial-legal protection of the original solutions.

| Annotation: | The aim of the project is the use of hybrid materials for high temperature applications aimed at reducing the wear intensity of the breech part of a large calibre artillery barrel system. Based on the analysis of tribogegradation factors and the current state of the art of material compositions, the project will design and experimentally test Fe-Ni-Co based material systems minimizing the development of surface degradation after repeated short-term thermal exposures. The material-technology concept includes in the design of the weld claddings the condition that the thickness of the weld layers should be greater than the area of cyclic thermal loading at the original surface. The aim of the modification is to limit the interaction of the combustion gases with the barrel breech material. The strategic role of the surface integrity solution is to prevent or delay the formation of primary non-integrity (such as cracks, non-integrity due to diffusion of gases from the combustion gases of the powder charge). The claddings will be made with a different chemical composition in order to increase the resistance of the cap materials to the action of tribodegradation factors. Thermodynamic calculations of phase equilibria and phase transformations will be performed. Experimental samples will be tested by NDT methods and laboratory tests by light, electron microscopy, XRD phase analysis and mechanical tests. Based on the results of the comprehensive material analyses, weld claddings, duplex PVD coatings and their combinations will be selected for firing tests in real gun barrels of a large caliber artillery barrel system. |

| Annotation: | Over the past few years, the interest in bone regenerative materials with antimicrobial properties has increased, since prosthesis infection is one of the most usual complications in implant surgery. Despite the increasing number of synthetic drugs with antibiotic and anti-inflammatory effects, research interest in natural substances, such as essential oils (EOs), remains still high. The terpenes and terpenoids found in essential oils represent a potential alternatives to synthetic drugs used for bone and joint healing, thanks to high inflammatory effect and the ability to inhibit bone resorption, subsequently leading to an increase of the bone mineral density.
Hence the incorporation of terpene EOs into frequently used bone substitute materials, such as calcium phosphate cements, represent a significant challenge addressed by the proposed CASOPUR project. The novelty and main contribution of the project will concern on the stabilization of EOs through citrate-based polyesters synthesis via esterification reactions, followed by deposition onto the CPC matrix using a solution infiltration technique. This approach offers an effective strategy for creating homogeneous polymer coatings on the cement matrix and developing polymer/CPC systems functionalized with natural EOs. The resulting biocomposites will exhibit not only improved physicochemical properties but will also support the healing and regeneration of bone tissue. The project aims to provide calcium phosphate bone cement with antimicrobial activity without harming its bone regenerative capability. Overall, the successful outcome of this project holds the potential to provide a bone-filling material for use in bone tissue engineering and regenerative medicine. An important aspect of such biomaterials is their potential to significantly reduce the risk of post-operative infections in patients undergoing orthopedic surgeries, thus enhancing the patients comfort and safety during these procedures.

Water electrolysis appears to be the most promising technology for hydrogen production. Bimetallic phosphide nanoparticles represent future substitutes for noble-free metals and critical materials in electrolysers and fuel cells. The main challenge of this project is to reduce hydrogen production and at the same time maintain the high efficiency of water electrolysis in membrane electrolysers. The main goal of the project will be dedicated to the improvement of electrode material. |

| Annotation: | This project aims to advance the field of materials science through the mechanochemical synthesis of metal chalcogenides, focusing on innovative methodologies and devices to enhance the efficiency and understanding of mechanically induced self-propagating reactions (MSRs). The first objective involves the mechanical activation of metals and chalcogens to produce fine, flaky, or delaminated precursors, which are crucial for optimizing the surface area and reactivity of starting materials. To complement this, we will develop a transferable device capable of monitoring pressure and temperature during planetary milling with subsecond resolution, providing valuable insights into the milling process and allowing for precise control over reaction conditions. Our investigation will also explore how the properties of selected reagents and milling conditions influence the ignition time of MSRs, aiming to elucidate the conditions that favor the formation of binary and ternary metal chalcogenides (MxCy, where M = Ag, Cu, Co, In, Ni and C = S, Se). Furthermore, we seek to identify the primary driving forces behind ball-free MSRs for selected metal chalcogenides, which will be critical for predicting reaction outcomes and improving synthesis strategies. Finally, we will explore the application potential of the synthesized products in electrocatalysis, particularly for hydrogen evolution reactions (HER). Through these interconnected objectives, this project aspires not only to produce novel materials but also to contribute to a deeper understanding of mechanochemical |

RNDr. Strečková Magdaléna PhD. |
| Annotation: | Human society is facing today significant challenges related to the climate changes induced by an intensive industrialization of economy and high carbon dioxide release to the atmosphere. In order to minimize important negative consequences of this phenomenon developed societies call for decarbonization of our economy and searching for alternative sources of energy, as well as raw materials for the industry. Here, hydrogen (H2) as the simplest and most abundant element in the universe can play an important role in a transition to a low-carbon economy. Green H2 – also referred to as “clean H2” is produced by using clean energy from surplus renewable energy sources, such as solar or wind power through a process called electrolysis. During electrolysis, water is broken down into hydrogen and oxygen molecules, and the hydrogen thus prepared can be consumed immediately or stored and used when needed. The main goal of this project is to contribute to economic viability of the green hydrogen production by reducing costs of electrocatalysts in future electrolyzes and fuel cells. This target will be achieved by the synthesis of the innovative non-noble metal electrocatalysts based on transition metal phosphides as the main components to proton exchange membrane electrolyzers. The key task will be devoted to the development of bifunctional electrode materials for hydrogen evolution reaction and oxygen evolution reaction with emphasis on maintaining low costs and high efficiency suitable for commercial applications. Completion of this target will help maintaining competitiveness in energetic industry in the starting period of economy decarbonization. |

| Project leader: |
doc. Ing. Chabak Yuliia DrSc. |
| Annotation: | This project focuses on developing novel functional materials, namely «Ceramics-Metal Matrix» composites, with advanced tribological properties for extreme wear applications. These composites will be fabricated using Selective Laser Melting (SLM), an additive manufacturing process, enabling fast prototyping of complex geometries. The core concept of these composites lies in combining hard ceramic particulates (with melting points exceeding 3000 °C, ensuring their stability during laser fusion) with an adaptive metallic matrix. This matrix will exhibit enhanced adaptability to wear impacts through a “smart“ response aimed at decreasing surface degradation, thus improving the matrix's durability and total composite integrity. The possible responses are deformation-induced martensite transformation, secondary phase precipitation, protective oxide scale formation, etc. The project fulfilment will encompass the design of the composite (phase constituents, powder size distributions, volume ratios, etc.), optimization of SLM parameters to produce defect-free 3D-printed components, and applying the post-SLM processing to boost the composite’s properties. The resulting composites will be tailored for different applications involving intensive abrasive, erosive, high-temperature erosion/oxidation. By combining the rapid prototyping capabilities of SLM with the advanced functional properties of novel composites, this project will enable the rapid repair of equipment while simultaneously extending the operational lifespan of machine parts. |

Emphasizing sustainability, the project uses green chemistry and low-temperature oxidative catalytic pyrolysis to synthesize FR-Oxygraphene from ecofriendly materials like cotton fibers, paper cellulose, and waste textiles, minimizing environmental impact. FROxygraphene, with a multilayer tubular structure, shows significant potential as an anode material. Its high specific surface area, excellent electrical conductivity, and large pore volume offer advantages over conventional graphite anodes. To improve electrochemical performance, heteroatoms like silicon will be incorporated into the material to overcome issues associated with conventional anodes, such as low capacity, low cycle stability, and limited conductivity. Optimizing this functionalization is crucial for maximizing FR-Oxygraphene's potential, leading to superior LIB performance. Project SMEBAT also focuses on battery cell design and validation. Laboratory-scale prototypes of Li-ion battery cells will be designed and fabricated to test FR-Oxygraphene anodes. Comprehensive electrochemical evaluations will compare FR-Oxygraphene to conventional graphite anodes, aiming to demonstrate superior capacity, charge-discharge rates, and cycle stability. The project aims to reach TRL5 by verifying the technology in an industrial environment, preparing modified FR-Oxygraphene as a suitable advanced anode material for LIBs. SMEBAT envisions developing LIBs that are powerful, environmentally friendly, and sustainable. By utilizing FR-Oxygraphene's unique properties, SMEBAT aims to create LIBs with higher energy density, faster charge-discharge rates, and longer cycle life, while reducing environmental impact. This aligns with regional, national, and European initiatives for sustainable energy storage solutions. |

| Annotation: | Development of biomaterials with antimicrobial properties is a highly topical issue to prevent the risk of infections after surgery. Terpenes are natural bioactive compounds present in essential oils with a significant therapeutic effects. They exhibit excellent antibacterial, antifungal and anti-inflammatory properties. However, disadvantages are high volatility, hydrophobicity and intense odor which hampers their direct application. Incorporation of essential oils into polymers is an effective method to increase hydrophilicity and stability of system with the simultaneous reducing of volatility. The aim of the project will be the stabilization of terpenes through a polymeric elastomer encapsulation, preparation and characterization of biocomposites consisting of matrix (biocement, bioceramic) modified with polymer coatings. The main task will be the production of biomaterial with better physico-chemical properties compared to individual components with potential application as hard tissue replacements. |

| Annotation: | The aim of the project is to investigate the susceptibility to hydrogen embrittlement (HE) of structural metallic
materials based on Fe (i.e. modern grades of carbon and alloy steels) as well as selected alloys or composites
based on non-ferrous metals (e.g. Al, Cu, Mg, etc.) by the method of electrochemical hydrogen charging and
mechanical testing in laboratory conditions. The microstructural conditionality of hydrogen embrittlement will be investigated on defined material states with characteristic microstructural parameters (grain size, phase composition, etc.). The possibilities of HE prevention will be investigated using available methods of surface modification (layers and coatings, surface alloying, formation of gradient structures, etc.) of basic materials in
order to apply a barrier effect against hydrogen permeability. |

| Annotation: | The biggest challenge of the today’s world is the Climate Change. The European Commission has proposed a significant number of measures to the European Union (EU) to reach the zero-carbon target in 2050. Advanced rechargeable batteries are gaining high importance in the transition toward carbon neutrality, affordable, secure energy, sustainable and smart mobility, and circular economy. In addition, batteries must be durable and based on ethically sourced materials, reduced negative environmental impact and be recycled, remanufactured or repurposed at the end of their life, returning
valuable materials to the economy. The Sunflower consortium was formed to address this by developing a novel battery components and hybrid battery energy storage system that simultaneously provides multiple services (mobile and/or stationary). Moreover, education in the field of energy storage is also important in time, when industry applies principles of electrification, decarbonization or decentralization. |

Mgr. Petrišinec Ivan PhD. |
| Annotation: | The project is focused on experimental research of the optimization of destructive and innovative non-destructive procedures for joining segments of different qualities of high-strength electrical steels in the cores of electrical machines. The jointing procedures proposed by us in combination with additional mechanical processing of sheets and subsequent unconventional thermal treatment of rotor and stator bundles aim to optimize the microstructure and texture not only of the lamellae themselves but also in the area of their joints to achieve the formation of a coarse-grained microstructure with preferred cubic {001}and Goss's {011}<001> texture. The magnetic properties of the join press clippings in the form of silicon steel toroids will be compared with the magnetic properties of the reference samples. A sequence of structure-forming processes will be proposed to achieve the set optimal conditions for joining the lamellae into bundles with the aim of minimizing magnetic losses. |
Development of Fe-Si alloys with double-oriented cube crystallographic texture

Mgr. Petrišinec Ivan PhD. |
| Annotation: | The scientific research project aims to develop Fe-Si electrotechnical steels with excellent magnetic induction isotropy and low watt losses. The project's concept is based on increasing the intensity of the double-oriented cube crystallographic texture within the sheet plane by inducing abnormal growth of ferrite grains through mechanisms involving inhibitory, diffusion-controlled, and deformation-induced grain boundary movement in the primary recrystallized microstructural matrix. To achieve a coarse-grained microstructure with a significant representation of grains possessing the required cube crystallographic orientation, Fe-Si steels will be designed using an original chemical concept. In these steels, innovative thermo-chemical and thermo-mechanical processing will create a complex of VC nanoparticles with a gradient distribution along their thickness. This will enable the abnormal growth of grains with cube texture components (111)[0vw] during dynamic heat treatment. The resulting microstructural and textural state of the steels will form the basis for achieving magnetic properties isotropy with relatively low wattage losses and a high isotropic value of magnetic induction. The output of the project will be, in addition to the knowledge obtained from basic research, a proposal for a technological procedure for the preparation of such a microstructure. |

Ing. Andrejovská Jana PhD. |
| Annotation: | The submitted project focuses on the problem of material wear, which we often encounter in technical applications, and addresses it through the use of composite ceramic materials with a reduced content of critical raw materials such as tungsten and cobalt, which are currently most commonly used for cutting inserts, bearings, and components in the automotive industry, where high wear resistance is required. These materials will be based on an affordable corundum or corundum–zirconia matrix. Within the project, the tribological properties of various ceramic systems will be tested, such as monolithic Al₂O₃, sintered carbides (WC–Co), and composites based on a corundum matrix, modified by the addition of up to 50 vol.% refractory carbides (e.g., ZrC, TiC, WC). The proposed experimental ceramic systems should exhibit improved properties, primarily increased wear resistance, higher hardness and oxidation resistance at elevated temperatures, a better performance-to-cost ratio, and reduced consumption of critical raw materials. |

| Annotation: | The global trend to reduce emissions has forced car producers to think about other types of propulsion than
internal combustion engines. A significant direction in which the world is currently moving in this area is the
replacement of internal combustion engines with electric car drives. This fact has led and it is still leading to a great
expansion in the production of car batteries, which would allow the longest possible range of electric cars. Besides
the capacity of the batteries, the efficient use of stored energy in electric vehicle drives has a significant effect on
the range of cars as well. This project aims to reduce losses and increase the efficiency of electric drives.
Increased efficiency and reduced losses can be achieved by reducing the losses in the materials of the rotors and
stators of rotating electrical machines, but also by reducing the losses that occur when changing the properties of the source material during cutting and subsequent joining into rotor and stator bundles. Experimental research will focus on optimizing the microstructure and texture of various grades of electrical sheets in order to minimize electromagnetic losses and optimize the conditions for the production of rotor and stator bundles by cutting and subsequent joining. The optimization of the conditions of joining electrical sheets of various chemical and microstructural concepts will be the expected output of the project. The magnetic properties of the joined electrical sheet cut-outs will be compared with the magnetic properties of the lamellas produced by electrospark cutting. |

Mgr. Oroszová Lenka PhD. |
| Annotation: | The project focuses on the development and research of medium and high entropy alloys for hydrogen storage. Currently, the most efficient and safest way to store H2 is its chemical bonding in the metal alloys lattices to form metal hydrides. The problem with current alloys is the too high temperature (exceeding 400 °C) at which H2 is released from their volume. The latest trend in material development in this area is towards microalloying of high entropy alloys with elements that can significantly reduce the desorption temperature of H2 from their volume. The amount of stored hydrogen can also be increased by plastic deformation of the matrix. Both of these approaches are the subject of this scientific project. Our main goal is to develop materials with high absorption capacity (> 2 wt.%), low desorption temperature < 140 °C and high cyclic absorption/desorption stability (> 1000 cycles with a capacity decrease of less than
10%). |

| Annotation: | The project is aimed at the development of novel cost-saving steel for ultrahigh-strength applications (ultimate
tensile stress not less than 2000 MPa under acceptable ductility/impact toughness) and the technology of its hot
deformation and heat treatment which can be easily integrated into the production lines present at the metallurgical
plants. The steel will not comprise the expensive alloying elements (Ni, Cr, Co, Mo, V), in contrast, due to using the
cheaper elements (such as Mn, Si, and Al which are lighter than Fe) it will acquire the lightweight feature. The main
objective will be reached through the formation of a multi-phase "smart" structure that can respond to the external
load by TRIP/TWIP effects leading to self-strengthening and stress relaxation. This structure will be developed by
means of appropriate chemical composition selection and the novel processing route design based on new
technological approaches and solutions allowing for a reduction of the processing duration, energy consumption
and using conventional "easy-in-operation" equipment. The results of the project will have a direct positive impact
on the metallurgical sector as well as on the users of ultrahigh-strength steels (machine-building, construction
sector) which will benefit from the reduction of steel cost and use the production-easy (time-saving) processing
technology. |

| Annotation: | Currently, several types of mateials(ceramics, polymers, composites of polymers and ceramics, and metal materials) are used in surgical practise as bone substitutes for traumatic injuries to the human musculoskeletal system. Metal materials mainly include titanium and its alloys, stainless steel, or cobalt-chramium alloys, which provide sufficient support for parts of the body that carry mechanical load during the healing process.
The new approach in implantology is the use of bioresorbable materials consisting exclusevely of elements that occur in the human body.
The aim of the project is to develop completely new types of biodegradable alloys, whose mechanical properties, biocompatibility, as well as adjustable degradation rate will lead to the develelopment of completely new materials for introcorporeal implants with the least invasive impac on the patient. |
