MechSustInd - CA18112: Mechanochemistry for Sustainable Industry
CA18112: Mechanochémia pre obnoviteľný priemysel
Program: COST
Project leader: RNDr. Baláž Matej PhD.
Annotation:Organic mechanochemistry has been shown to enable the reduction, or the elimination, of solvents, while ensuring increased yields and scope of substrates compared to solution-phase synthesis, better crystallinity of final products, and access to products that can be formed only under mechanical activation conditions. This COST Action aims at establishing a multi-disciplinary network of European scientists, engineers, technologists, entrepreneurs, industrialists and investors addressing the exploitation of mechanical activation in the production of chemicals through sustainable and economically convenient practices on the medium and large scales. Specifically, this Action addresses the objective of harmonizing fundamental and applied research with technological innovation and industrial needs, representing the necessary step for enhancing the impact of mechanical processing onto organic synthesis and transferring specific knowledge into the industrial value chains. The Action aims to nucleate a critical mass of actors from EU research Institutions, enterprises and industries, bringing together different areas of expertise and application. The creation of an authoritative community to promote the study of mechanochemistry and encourage its utilization in production processes will catalyze strategic advances in European chemical industry. The favorable features of mechanically activated (organic) transformations is expected to enable the attainment of far-reaching objectives connected with the development of green economy, the improvement of European market competitors’ capabilities, the innovation of process engineering, and the growth of a new generation of specialized researchers.

Preparation of Materials for the Remediation of Old Mining Sites.
Príprava materiálov pre remediáciu environmentálnych záťaží po banskej činnosti
Program: VEGA
Project leader: Ing. Václavíková Miroslava PhD.
Annotation:Due to intensive industrial activities, many pollutants such as heavy metals, radionuclides and other substances including organic once enter the environment and have been identified as highly toxic and harmful to human health. Heavy metals are non-biodegradable species. In the aqueous environment they occur in dissociated forms (as cations i.e. Cd2+, Pb2+, Cu2+, Zn2+; anions/oxyanions i.e. HAsO42-, CrO42-, HSeO4-, HSeO3-, HMoO4--). One of the priority sources of heavy metals in Slovakia are old and/or abandoned mines with the significant streams of acid mine drainage (AMD) waters. The objective of the project is the synthesis and investigation of composite sorbents based on Fe oxides for the removal of both cationic and anionic forms of heavy metals/metalloids from aqueous media. Moreover, the sortion affinity towards the selected organic contaminants such as polyaromatic hydrocarbons will be investigated as well.

The subject of the project is preparation and study of multicomponent filters properties, composed from the natural materials (quartz sand, siderite, pyrite) and synthetic prepared materials (iron and manganese oxides/hydroxides) that will be used for cleaning of leaching media containing toxic elements. The original gain of the project will be the definition of optimal ratio of particular filters components for the most effective recycling of media containing different concentrations of toxic ions in dependence of locality and soil contamination. The greatest accent will be focused on the arsenic removal.

Program: VEGA
Project leader: RNDr. Baláž Matej PhD.
Annotation:The research project is focused on mechanochemical synthesis of the selected nanomaterials via combination of high-energy milling and green approach using precursors based on minerals, natural materials and waste. Mechanochemical reduction will be aimed at preparation of nanocrystalline metals with bactericide effects (Ag, Cu). At the same time, the project will be focused also environmentally, because the application of mechanochemistry will be tested on elimination of halogenated compounds and sorption of toxic metals present in wastewaters after mining and metallurgical activities. Environmental aspect will also resonate by research of selected organic reactions where solid state approach via mechanochemistry can be realized through solvent-free technology. Available characterization methods will be applied for products characterization and monitoring of environmental parameters.

ZVNI - Development of a system for continuous monitoring of pollution impact on the high-voltage insulation
Vývoj systému pre kontinuálne monitorovanie vplyvu znečistenia na vysokonapäťovú izoláciu
Program: APVV
Project leader: RNDr. Fabián Martin PhD.
Annotation:The dynamics of the environmental pollution is affected by the industrial emissions and the ongoing climate change. The environmental pollution on electrical insulation is one of the problems faced by distribution utilities and electricity transmission system. Moreover, it can be classified as a potential danger for reliable operation of an electric power system. Seasonal conversions affect the tendency accumulation of contaminants on the surface of insulators and cause chemical changes which influence their original characteristics. This fact needs to be addressed, as mentioned insulation is an important part in the chain of the transmission and the distribution systems reliability. Current knowledge points to the fact that, depending on the profile of the insulator, the pollution, the humidity and the temperature of the surface are strongly related to the insulation withstand. External pollution modifies the electrical breakdown strength of isolation. In Slovakia, thousands of insulators are included in the electricity transmission and distribution systems. Nevertheless, at present time in Slovakia no information is gathered about the current state of pollution in key areas of strategic energy objects. The project is focused on the development of modern equipment, enabling real-time monitoring of insulator surface condition either in autonomous mode or as part of an existing network-based IT infrastructure with a remote dispatching control system. This proposal of research and development is invoked by the project implemented within the EU

Program: VEGA
Project leader: RNDr. Dolinská Silvia PhD.
Annotation:The mineral waste coming from mining (mineral processing), metallurgy and coal-fired power industry can be also treated as a significant source of so called critical mineral raw materials or possibly elements. Submitted project proposal includes detailed analysis of the following selected waste from Slovakia: black coal fly ash (Košice), tailings from flotation and polymetallic ore processing (Markušovce), bauxite residuum (dump of red mud after Bayer process, Žiar nad Hronom), from viewpoint of critical elements abundance. On the basis of obtained data physical and physico-chemical techniques of critical elements beneficiation will be proposed. An extraction of critical elements by various chemical agents and an optimization of leaching process will be performed. Chemical and physico-chemical methods will be applied in selective separation of critical elements from leachates. An influence of microwave energy on efficiency of critical elements extraction from waste will be also investigated.

AuMCHBA - Gold recovery from refractory sulphide concentrates by mechanochemico-biological activation
Získavanie zlata z ťažko spracovateľných sulfidických koncentrátov s aplikáciou mechanochemicko-biologickej aktivácie
Program: VEGA
Project leader: Ing. Ficeriová Jana PhD.
Annotation:The demanding processing of gold-containing concentrates, as well as dangerous cyanide method for gold recovery encourage the application of new ways to obtain this precious metal. Therefore, the aim of this project is obtaining gold from refractory sulphide concentrates by using of non-cyanide mechanochemico-biological processes. Mechanochemical activation of concentrates and siliceous shells of specified algae in the non-cyanide environment causes changes in the physico-chemical properties of gold minerals as well as algae mineral constituents. These structural changes have a decisive influence on the formation of gold nanoparticles into non-cyanide media under the specific reaction conditions, from which they are subsequently fixed in the cellular matrix of mechanochemically activated algal shells. Gold nanoparticles can have various utilization in practice, such as accelerating the breakdown of hazardous substances or disposal of pollutants from contaminated water, soil and air.
