Bifunctional Silica and Magnetite Spherical Particles with Tailored Porosity and Surface Chemistry for Complex Water Treatment
Bi-funkčné sferické častice na báze kremíka a magnetitu pre čistenie vôd
Program: FP7
Project leader: Ing. Václavíková Miroslava PhD.
Annotation:Project aims to develop bi(or multi)functional silica and magnetically removable adsorbents for water purification and remediation securing removal of chemical pollutants both organic and inorganic nature. SASPRO will unite the efforts of the scientists and their expertise in two adjacent fields - synthesis and functionalization of mesoporous silica and silica-based adsorbents from the Marie Curie Fellow Dr Melnyk and advanced experience in physicochemical characterization of surface binding with valuable experience of their implementation in water purification from the Institute of Geotechnics SAS. Our specific aims: 1) Creation of silica microsheres with well defined composition for selective uptake of metal cations. 2) Сombination the properties of magnetite (easy removal from the reaction medium, recovery) with the assets of functionalized polysiloxane (specific groups, large specific surface area) and contribute to the selective removal of contaminating cations and organic molecules simultaneously. 3) Synthesis of nanocomposite multi-functional microparticles, testing them on wastewater samples modeling complex water systems. The goals will be achieved through coordinated research uniting the efforts of specialists in materials synthesis, characterization and application. In addition these materials are promising for applications in chromatography, drug delivery, creation of chemo- and biosensors, etc.

Mechanochemical Activation and Synthesis – An Ecological Friendly Process in the Production of Materials for Photocatalytic Air and Water Purification
Mechanochemická aktivácia a syntéza - ekologicky prijateľné procesy prípravy materiálov pre fotokatalytické čistenie vody a ovzdušia
Program: Inter-academic agreement
Project leader: RNDr. Fabián Martin PhD.
Annotation:Doping of simple oxides (e.g. TiO2, ZnO, Fe2O3 etc.) by nitrogen results in formation of oxygen defects and shift of optical wavelength absorption maximum from UV to visible region. This fact has a great influence on preparation nanocrystalline photocatalysts working not only with UV but also with visible light. Due to the project we have prepared N doped TiO2 and ZnO. The change of their colour indicates the shift of absorption maximum from UV to visible region. This behaviour was further confirmed by DRS spectroscopy. Microstructural changes were evaluated by XRD and XPS analyses. At the present the as-prepared materials are tested for photocatalytic activity on azodyes (liquid phase) and ethylene (gas phase).
Duration: 1.1.2015 - 31.12.2018

Nanoporous and Nanostructured Materials for Medical Applications
Nanopórovité a nanoštruktúrne materiály pre medicínske aplikácie
Program: Horizon 2020
Project leader: Ing. Václavíková Miroslava PhD.
Annotation:The main focus of this project is on developing advanced and more efficient methods of treatment of radiation sickness, radio-related toxicity, heavy metal poisoning and radiation cancerogenesis prevention. In this inter- and multidisciplinary project the applicants bring together complementary expertise in physical chemistry and chemical engineering, pharmacology, biochemistry, toxicology and medicine that would be transferred across the discipline boundaries and bring innovative and original solutions to develop a nanoporous sorbent-based method of health protection by adsorbing the target substances that are not currently removed or neutralised by alternative existing systems.

Solutions for Critical Raw Materials Under Extreme Conditions
Riešenie problému kritických surovín pre materiály v kritických podmienkach
Program: COST
Project leader: Dr.h.c. prof. RNDr. Baláž Peter DrSc.
Annotation:Project is aimed at substitution of critical raw materials used in preparation of advanced alloys and composites under extreme conditions of temperature,loading, wear and shear in energy,,car and traffic sectors
Duration: 10.3.2016 - 9.3.2020

Development of Magnetic Composites with Adjustable Hydrophobic and Hydrophilic Surface
Vývoj magnetických kompozitov s kontrolovaným hydrofóbnym a hydrofilným povrchom
Program: Inter-academic agreement
Project leader: Ing. Václavíková Miroslava PhD.
Annotation:The joint Ukrainian-Slovak project is supposed to result in the detailed study of the effect of the conditions of magnetite functionalization on hydrophobic and hydrophilic properties of the coating layers. The surface of the obtained materials will be characterized by the presence of different types of dominant groups, specific functional groups selective to particular metal or group of elements; electron withdrawing or electron accepting groups, both from hydrophobic hydrocarbon radicals attached to the silicon atom and from organic groups directly incorporated in the silica framework (it is an organic bridge for bridged silsesquioxanes); residual silanol groups, and oxygen atoms of the siloxane bond. Such nature of sorbents surface will enable different types of interactions with different sorbates.
Duration: 6.4.2017 - 31.12.2019
