AtomDeC - Atomic Design of Carbon-Based Materials for New Normal Society

Atómová koncepcia materiálov na báze uhlíka pre novú normálnu spoločnosť

Duration: 1. 11. 2021 - 30. 10. 2024
Program: Multilaterálne - iné
Project leader: Ing. Scholtzová Eva CSc.
Annotation:The expression “New Normal'' has been used for marking economic/societal goals after the 2008 financial crisis. Nowadays, this term is used for emerging lifestyles at the end of the COVID19 pandemic. Our proposed work relates to the “New Normal Society” by means of contributing to the creation of an upgraded, human-centred society (Japanese “Society 5.0”), where new technologies serve sustainable developments, mitigate the threat of future pandemics, and are devoted to human welfare. We aim to contribute to the worldwide target via the development of advanced carbon-based materials (CBMs). CBMs are key in everyday applications and devices: batteries, power generators, energy converters, mobile devices, structural materials, environmental filters, health care, and medical products. The Consortium is formed from representatives of three continents: each V4 country, Japan, and Canada. Our collective scientific power is focused on advanced CBM target materials by adhering to the concept of “atomic design”, which has been challenging to achieve for C-materials with disordered/amorphous framework. Our integrated work packages will be executed by experts in synthesis, analysis, and theory giving credibility to the deployment of the concept of "atomic design" for CBMs. The Consortium directly addresses the Joint Call for developing advanced materials for extreme environments, electronics and energy harvesting, such as gas storage, flexible electrode/supercapacitors/conductive thin-layers, microelectronics, and optically active materials with high voltage/structure stability. The unique mechanical properties of porous CBMs and our combined engineering expertise allow for targeting COVID19-related material design, such as anti-virus filters.

BENTONITE - GAP - Bentonite: Slovak strategic raw material - Innovative assessment of bentonite quality and origin for its efficient use

Bentonit: strategická surovina Slovenska - inovatívne hodnotenie zdrojov a ich kvality pre jej efektívne využívanie

Duration: 1. 1. 2021 - 30. 6. 2025
Program: APVV
Project leader: RNDr. Madejová Jana DrSc.
Annotation:Bentonite is an important industrial raw material. Due to the high amount of clay minerals from the smectite group, bentonite has unique properties, e.g. high swelling capacity, plasticity, high specific surface area, cation exchange capacity and low hydraulic conductivity. Due to these properties bentonites have broad range of possible applications. Consequently, worldwide bentonite production is constantly increasing. Slovak republic (SR) is one of the world's leading bentonite producers and bentonites belong to the strategic raw materials in SR. In the last 10-15 years, several new bentonite deposits have been opened in SR, most of which have never been studied in detail. Which is one of the causes that the potential of Slovak bentonites is not fully utilized. One of the objectives of the project is therefore the comprehensive characterization of bentonites from new deposits. The mineral and chemical composition of bentonites, their physico-chemical, mechanical, and rheological properties will be determined. The obtained results will help to better understand the geology and genesis of bentonite deposits which may lead to the discovery of other economic accumulations of bentonites. The main contribution of the project lies in the rational, economical, and efficient use of domestic raw materials which will lead to the long-term sustainability of bentonite exploitation in SR. The way in which the proposed changes will be implemented is highly innovative. The main application outputs of the project such as: passports for the optimal utilization of different qualitative types of bentonites, including economic analysis, 3D model of bentonite quality and geological model of selected bentonite deposit, will contribute to achieve this ambitious goal. The multidisciplinary team of experts on domestic and world bentonites in cooperation with major bentonite producer in SR, REGOS, s.r.o. is guarantee of successful solution of the proposed project.

BioPolSil - Bionanocomposites based on organic polycations and layered silicates

Bionanokompozitné materiály na báze vrstevnatých silikátov

Duration: 1. 7. 2020 - 30. 6. 2024
Program: APVV
Project leader: RNDr. Madejová Jana DrSc.
Annotation:The basic research project deals with the preparation and complex characterisation of the structurally unique types of hybrid materials consisting of clay minerals from smectite group and new synthesized poly(ethylene imine) based polycations. Polymerization of oxazolines opens a wide range of possibilities for the preparation of welldefined polycations with precisely designed molecular architectures and properties in order to prepare suitable intercalating agents for clay minerals modifications. The aim is to provide nanocomposites with interesting biocompatible or biodegradable properties. To achieve this aim a detailed investigation of the effect of various factors on the molecular characteristics of poly(ethylene imine) based polycations and consequently on their behavior upon smectites interlayers intercalation has to be performed using wide range of different experimental technique (e.g., XRD, XPS, MAS NMR, and IR spectroscopies) but also by means of DFT method in the solid state. Biocompatibility of prepared polycations and their smectite intercalates will be assed based on cell viability assay and cell morphology after direct contact with selected substances. Prepared polycationic-smectites will be further studied due to their possible applications as new types of fillers for selected biodegradable polymers, drug-delivery systems and as new composite materials with optical properties. Interdisciplinary project, as designed, provides unique platform for understanding the properties of the newly synthesized polycation-smectite composites. This approach can significantly contribute to the current level of knowledge in the fields of nanomaterials and has the potential for acquiring fundamentally new results.

"solvents" which may be considered to be some binary fluoride MF or NF2 (M = Li, Na or K; N = Mg or Ca) or selected eutectic mixtures thereof (e.g. (LiF-NaF-KF)eut = FLiNaK, (LiF-CaF2)eut or (NaF-MgF2)eut), . Ln2O3 metal oxides (Ln = La, Ce, Sm, Eu, Nd, Gd), or transition metal oxides used in superalloys (e.g. Cr2O3, Fe2O3, NiO, ZrO2, Nb2O5, Ta2O5), . and the corresponding metal fluorides of the point above (LnF3, MetFx; x = 2-5). Such systems are currently in use or are being developed for their use in key industries such as metal production, energy applications or corrosion protection. The scientific activities of these systems deals with physico-chemical and thermo-chemical analysis of the systems in molten state (in situ), spectral and diffraction analysis of formed phases. The selection of used methods follows the above aims: thermal analysis, density, viscosity, surface tension, wetting and electrical conductivity measurements for the description of physico-chemical properties; simultaneous thermal analysis (TA/DTA/DSC) for the description of thermo-chemical properties and for the description of spectral and diffraction properties the following methods will be used: XRD, XSC, XRF, XPS, IR, NMR. The integral part of the project is the study of corrosion resistance of different construction under interaction with studied melts.

NanoBioFit - Nanostructured, functionally graded, and bioinspired 3D Ti-based implants

Nanoštrukturované, funkčne navrstvené a bio-inšpirované 3D iplantáty na báze titánu

Duration: 1. 8. 2021 - 30. 6. 2025
Program: APVV
Project leader: doc. Ing. Hnatko Miroslav PhD.
Annotation:In general, patient response to implants is strongly dependent on the host tissue ─ implant interface because processes such as healing, osteolysis, and infection take place specifically at this interface. Therefore, modification and tailoring of transplants surface properties are attractive methods to trigger and accelerate healing processes and to reduce the possibility of osteolysis and infection. The main goal of the project is oriented towards improving the adhesion of bio-coatings on titanium alloy surfaces and ensure the enhancement of bio-compatibility of the bio-inert implants. Therefore, the main goal will be divided into two interconnected parts. The first part will be devoted to electropolishing of titanium and titanium-based alloys. This electrochemical surface treatment is generally considered as one of the most efficient, convenient and adaptable technique for the improvement of the physical and mechanical surface properties of materials. The second part of the project will deal with the preparation of bio-compatible surface layer on Ti implants by: - the formation of TiO2 nanotube arrays by anodic oxidation of Ti-based alloy - electrophoretic deposition (EPD) of coatings based on bio-composites such as polymers doped with various bioactive glass prepared by glass melting or sol-gel process (with possible antibacterial and inflammatory effect). Introduction of the convenient surface treatment process together with highly bioactive coating materials on bioinert Ti-based 3D implants will allow us to provide personalized, well-fitting implants without the need of additional medical treatment. Significant enhancement of patient comfort together with the reduction of the medical costs will be the main benefits of the presented project.

Duration: 1. 1. 2019 - 31. 12. 2022
Program: VEGA
Project leader: Ing. Scholtzová Eva CSc.
Annotation:Proposed project presents a combined theoretical and experimental research of surface complexes formed by selected pollutants (oxyanions, herbicides, medicaments) on layered aluminosilicates (LAS) and aluminosilicate nanotubes (ASN). The pollutants can be strongly dismantled by adsorption on aluminosilicates, e.g. from polluted water. The study of these surface complexes will be focused on the detailed (molecular scale) description and understanding of the interactions responsible for the formation and stability of the complexes. Further, the effect of solvent on the stability of the complexes will be investigated as well. Molecular modelling approach, mainly based on the density functional theory (DFT) will bring a new knowledge about structure and properties of LAS/ASN surfaces and their ability to form stable complexes with pollutants. The results from experiments will be also interpreted by help of the modelling outputs to get a complex characterization of the pollutant-aluminosilicate complexes.

Potential of layered aluminosilicates as excellent guests to accommodate polymeric cations: design of new composite materials

Potenciál vrstevnatých aluminosilikátov ako excelentných nosičov polykatiónov: dizajnovanie nových kompozitných nanomateriálov

Duration: 1. 1. 2021 - 31. 12. 2024
Program: VEGA
Project leader: Ing. Pálková Helena PhD.
Annotation:The project is aimed at the preparation of composite materials based on layered aluminosilicates as suitable carriers for different types of organic polycations, possessing properties interesting for various applications. The variability in the chemical composition of the selected layered materials in connection with the diversity of the molecular structures and properties of polymeric cations and copolymers opens up wide opportunities towards the preparation of well-defined systems. Careful selection of the inorganic carries and polycations is an essential step to achieve their mutual compatibility resulting not only in preserving but primarily in improving the key properties of the prepared composites. Therefore, the synthesis conditions (e.g. pH) and the addition of another component to the systems (fluorescent dyes, metal nanoparticles) will be evaluated. The cytotoxicity test to predict biocompatibility of the materials, photoactivity, catalytic and adsorption efficiency will be assessed as well.

Program: APVV
Project leader: Ing. Pálková Helena PhD.
Annotation:The project is an interdisciplinary basic research on nanocomposites of technically used polymers whose functionality depends on the properties of the organic dyes present. The aim will be to provide nanocomposites with an increased particle concentration on the surface of the polymer. The particles must be pretreated with organic surfactants prior to the synthesis of nanocomposites to achieve compatibility with the polymer, which will be one of the main tasks of the project. In the next step, the modified particles will be functionalized with dye molecules and used to prepare nanocomposite. The surface functionality will be achieved by suitably selected dyes with interesting photophysical and photochemical properties. The goal will be to obtain surfaces which are attractive in terms of possible applications such as photosensitizing and photo-disinfecting properties, luminescent surfaces, systems capable of intermolecular light energy resonance transfer, etc. The selection of the dyes used will be directed to both to commercially available laser dyes and to photosensitizers mainly from the xanthene and thiazine dye groups, as well as to newly prepared fluorescent dyes.

Project leader: Ing. Michálková Monika PhD.
Annotation:This project addresses the development of new materials in the form of vitreous microspheres, prepared via flame synthesis, and their utilization in 3D glass and glass-ceramic structures. The project focuses on the optimization of the flame synthesis parameters (i.e. the length vs temperature of flame ratio, the red-ox conditions of ignition, or the precursor feeding rate). These conditions influence the chemistry, structure, and morphology of synthesized microspheres. Full, hollow and porous microspheres will be prepared in aluminate, silicate, borate and boro-silicate systems, which, in many cases such compositions are difficult to achieve via conventional glass-making methods. Hollow and porous microspheres will be prepared via alkali activation or the addition of porogens. Microspheres will be used for the preparation of advanced 3D structures via the Additive Manufacturing Technology (3D print), which utilizes Direct Light Processing, Direct Ink Writing and Hot Isostatic pressing

DKS-pNMR - Development of tools for advanced analysis and prediction of parameters of EPR, NMR and pNMR spectra of complex systems containing heavy elements

Vývoj nástrojov pre pokročilú analýzu a predikciu parametrov spektier EPR, NMR a pNMR komplexných systémov obsahujúcich ťažké prvky

Duration: 1. 7. 2020 - 30. 6. 2024
Program: APVV
Project leader: Dr. Malkin Oľga DrSc.
Annotation:The project is oriented to the development and implementation of new computational tools for advanced prediction and analysis of parameters of EPR, NMR and pNMR spectra of complex systems containing heavy elements with the stress on systems possessing low-lying excited states. Low-lying excited states strongly affect EPR and pNMR parameters and they must be taken into account for accurate prediction of these parameters. The calculation and interpretation of properties of low-lying excited states requires a more advanced methodology than the calculation of ground state properties. Nowadays one of the best approaches for treating excited states of large systems is the time-dependent DFT method (TDDFT). Recently our group implemented relativistic four-component and twocomponent TDDFT methods and made some preliminary steps towards calculations of EPR properties for the excited states. In this project we plan to further develop the TDDFT methodology in order to improve the accuracy of the predicted pNMR parameters for systems with low-lying excited states. We also plan to develop and implement new tools for better interpretation of EPR, NMR and pNMR parameters for heavy-element compounds. Finally the developed methods would be applied for systems of real chemical interest in collaboration with our foreign partners from experimental groups.
