Syntesis and characterization of novel organic-inorganic polymeric hybrids for 3D printing
Príprava a charakterizácia pokročilých anorganicko-organických polymérnych hybridov pre 3D tlač
Program: Medziakademická dohoda (MAD)
Project leader: Ing. Bureš Radovan CSc.
Annotation:Three-dimensional printing is currently largely bound to the use of polymer materials supplied by the printer manufacturer. This, however, greatly limits the wider application of 3D printing of objects with specific physicochemical and mechanical properties. The primary reason of this limitation is the requirement for biocompatibility, biodegradability, enhancement of anti-corrosion properties, or specific requirements for the mechanical and electrical properties of the resulting products. Consequently, the objective of this project is the synthesis and characterization of novel advanced polymer composites with inorganic fillers applicable in 3D printing. The aim will be to examine the influence of the size and shape distribution of inorganic fillers on the structure and physicochemical properties of the newly formulated composites. Increased attention will be paid to modifying the macromolecular structure and microstructure at the interface between the organic and inorganic phases and unveiling the induced changes in the macroscopic properties of the infiltrated hybrid materials.

Progresívne metódy úpravy funkčných a mechanických vlastností práškových materiálov
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Kovaľ Vladimír PhD.
Annotation:Rapidly solidified powder alloys as well as mechanically prepared powder metal alloys have a limited plastic deformation capability. Limited plasticity of the powders leads to their limited form-ability and in some cases prevents compacting of the powder by uniaxial cold pressing. Structural defects typical for mechanically synthesized alloys also cause deterioration of their electrical and magnetic properties. The aim of the project is to investigate the progressive processing methods of mechanically prepared powder alloys in order to improve their compaction, while maintaining or improving their electrical, magnetic and mechanical properties. The project solution can bring original findings, leading to expansion of the usability of fast-solidified and mechanically synthesized alloy powder materials in industry.

MagElMat - Development of novel multifunctional materials for next generation magnetoelectric sensors and data storage devices
Vývoj nových multifunkčných materiálov pre magnetoelektrické senzory a úložiska digitálnych dát budúcej generácie
Program: Bilaterálne - iné
Project leader: RNDr. Kovaľ Vladimír PhD.
Annotation:The main goal of the proposed project is to establish and develop a scientific cooperation between Slovakia and China in the field of multifunctional materials for advanced applications in microelectronics and spintronics. Joining of the research teams from both countries is motivated not only because of great technological potential of multifunctional materials but also due to the fascinating physics behind their unique properties. Multiferroics, exhibiting simultaneously ferroelectric and magnetic properties, are among the most attractive multifunctional materials. They allow for controlling the magnetic state of multifunctional devices with an external electric field, and vice versa. The main obstacle is, however, the scarcity of multifunctional magnetoelectrics in nature. Currently, single-phase multiferroics are far beyond any practical application, because they only demonstrate useful properties at very low temperatures. Recently, we showed that Aurivillius-type ferroelectrics doped by magnetic atoms can exhibit multiferroic behavior at room temperature. The origin of magnetism and magnetoelectric coupling in these materials, however, still needs a proper interpretation and confirmation from detailed experimental and theoretical studies. Our aim is to combine research on multiferroic materials in Slovakia with activities in China on theoretical modelling of multiferroics to design and prepare single-phase materials with the improved magnetoelectric property at room temperature.

For this renovation purpose will be used hard surfacing of functional surfaces of tools in combination with PVD and PE-CVD coatings made of new advanced nanomaterials based on TiAlN, CrAlN and TiB. There will be experimentally verified the effectiveness of local heat exposure of renovated as well as original surface of shaped casting mould to laser as a method of surface pretreatment before deposition thin coatings using PVD or PE CVD technology. The application potential of the project lies in reducing the cost of maintenance moulds and dies, in saving of material resources and also in increasing the productivity and reliability of the process of aluminum castings production.

BiAll - Development of new biodegradable metal alloys for medical and prosthetic applications
Vývoj nových biodegradovateľných kovových zliatin určených pre medicínske a protetické aplikácie
Program: APVV
Project leader: Ing. Saksl Karel DrSc.
Annotation:In the submitted project we aim to prepare and investigate ultralight amorphous alloys been made exclusively from bioabsorbable elements (Ca, Mg, Zn, Sr, Si, Zr, Li), existing in human body and to which the body has inherent tolerance. Applications of these materials are foreseen in the field of medicine - for implants with targeted dissolution in patient body. Metallic glasses based on bioresorbable chemical elements are interesting due to the unique combination of properties: very low density, Young’s modulus and hardness similar to human bones and toughness exeeding 300MPa. During the poject we will made series of new alloys not presented up to date on which we will characterise atomic structure, thermal stability in addition to functional properties as: mechanical, electrical conductivity, corrosion resistance in enviroments similar to human body solutions as well as cytotoxicity of the osteoblastic cells on their surfaces. Determination of atomic structure of highly disordered materials belongs to the most complicated experimentally theoretical procedures in materials research and in condensed matter physics. Within the project we plan to do also very ambitious experiments on X-ray free electron laser aiming to study dynamics of the solid state systems sampled in femtosecond timescales by X-ray photon correlation spectroscopy. Goals of this project are highly ambitious but achiavable will require application of the most sophisticated methods applied today in material research. The previous experiences of the research team proved by more than 70 scientific papers published in most prestigious scientific journals like Nature Physics, Physical Review Letters, Applied Physics Letters etc. we believe guarantees their fulfilment.

ZELASHYK - Increasing the efficiency of forming and joining parts of hybrid car bodies
Zvyšovanie efektívnosti lisovania a spájania dielov hybridných karosérií
Program: APVV
Project leader: RNDr. Džupon Miroslav PhD.
Annotation:Nowadays, there is a characteristic continual pressure on the emission reduction produced by the cars. One possible way to reduce the amount of emissions produced by the automobiles is the reduction of the body weight. The weight of the automobile could be reduced through the hybrid car body, which consists of different materials based on the light alloys, composite materials and high-strength steel sheets. Solutions related to such hybrid car body designs must be addressed in to the forming, but also to the joining of the individual parts of such multi-material conception. The aim of the project is the optimization of the forming conditions of aluminium alloy sheets and high-strength steel sheets to increase the process efficiency. The appropriate joining technique will be proposed based on the results of the analyses of the stress-strain states of the formed parts. A comparison of strength and load-bearing capacity of the joints after different intensity of deformation and stressstrain states will be the assumed result. Effective and innovative methods of joining of aluminium and highstrength steel sheets after different intensity of deformation and stress-strain states will be assessed. The results obtained from the optimization of the joining process of the materials made of ferrous and non-ferrous metals will allow the strength of joints to be increased.
