Annotation: | The project is expected to develop an innovative strategy for remediation of the area of the former Pavlodar (Kazakhstan) chemical plant from mercury toxic forms using data on occurrence of mercury species (including methylmercury, mobile and bioavailable forms). These forms, determined by modern physicochemical and analytical methods, will help to assess the Hg mobility, toxicity and the ability to methylation at this location and will make it possible to propose a rational approach to remediate the territory. In addition, it is planning within the project to develop and offer for commercial use at least one material/product as an in situ amendments to stabilize/immobilize mercury in soils and/or to remove it from water.

Annotation: | Feldspathic ores containing mainly K-Feldspar (KAlSi3O8) will be valorised by applying several hydro- and pyrometallurgical processes at which KCl, Al2O3, and SiO2 will primarily be produced without generating any solid waste. Objective is to provide new resources for potash
and alumina. Targets are to produce fertilizer-grade KCl, high purity Al2O3, synthetic SiO2, Ca-silicate, and SiC from one ore and to sequester CO2 on the same ore.
Although there are many studies for K and Al2O3 recovery from feldspars and clays, there are no notable commercial attempt to date. Unlike the other KCl and Al2O3 production methods suggested in the literature, manufacturing KCl, Al2O3, SiO2, Ca-silicate and SiC from the same ore without generating any waste is the novelty of this project. Thus, innovative aspect of the project is that feldspathic ores will be processed as a source of high value-added materials for the first time and with zero-waste approach, thus increasing the economic value of the proposed process. Also, CO2 sequestration capability of the feldsphatic ores will also be verified to enhance the economic importance those types of resources. For increased raw materials efficiency, a novel, hybrid and zero-waste processing method will be put forward. This will be established by exploiting the ores, other than bauxite and natural potash ores, and by applying environmentally sensitive production processes. The project will unlock substantial volume of various raw materials from deposits that cannot be economically or environmentally exploited within or outside the EU through enabling the better efficiency of exploitation of raw materials’ resources and increasing the range and
yields of recovered raw materials; and push Europe to the forefront in the area of raw materials processing technologies and increase availability of recovered raw material and create added value products through reducing the amounts of industrial tailings to be disposed or landfilled. |
Supported Co-Pd catalysts for CO hydrogenation synthesized by impregnation and mechanical activation or by mechanical alloying

Annotation: | The project aims to enrich and refine the knowledge about the type, role and
significance of various factors determining the structure and properties of supported
bimetallic Co-Pd catalysts for CO hydrogenation like supported metal(s) dispersion,
degree of metal reduction, surface structure of metal particles, extent of the metal
phase components influence on the type and properties of adsorbed atoms and
compounds, role of support composition and surface properties. Enrichment and
clearance of details of the catalytic CO hydrogenation mechanism could be
obtained.
The main hypotheses for the study are:
- The selectivity and distribution of reaction products is determined by the reduction
and dispersion of the metal, as it is established that the main active phase are
metallic nanoparticles where essential part of their surface consists of totally
reduced cobalt atoms (Co0
) but some results show necessity of Co0
/Con+ couples.
- The type of CO adsorption, formation of various CO species will depend on the
surface composition of the studied material - namely the presence/ratio of metal ions
and atoms of the catalytically active components.
- Mechanochemical synthesis of catalysts for CO hydrogenation could be profitable
for simultaneous desirable modification of support surface properties

Multifunctional sustainable adsorbents for water treatment assisted with plasma technologies and for health protection from xenobiotics

Annotation: | Contamination of drinking-water is an urgent global health concern, preferentially in rural areas, and is highly related to the poor and vulnerable population. This challenge requires a single, easy to handle and low-cost solution able to decrease the levels of pathogens, chemical and radiological hazards to tolerable levels in a single and simple pot (from a sorbent on a glass to a more powerful cold plasma technology). Furthermore, climate change, natural disasters and the actual war in Ukraine urges having available fast effective solutions to avoid the spread of waterborne epidemies and being exposed to unsafe levels of heavy metals or hazardous organic pollutants. The complexity of such contamination including organic/inorganic species, cationic/anionic species, different size and shape, etc., requires a multicomponent system and/or device, in the form of a tablet or monolith, able to tackle specifically each of these hazards at once. In addition, this multicomponent system, besides tacking the problem in water, can be prepared and/or modified to be biocompatible so that it can also be used as a dietary complement to mitigate/remove all these hazards in human body (as enterosorbent). Based on these premises, the main goal of the CLEANWATER project is the design and development of multicomponent sorbents prepared by the combination of safe materials (e.g., activated carbons, bone-chars, pectins, among others) able to eliminate these contaminants in drinking water in a single pot or in combination with cold plasma for complete destruction. Furthermore, this sorbent will be modified accordingly to be applied in human body as a dietary complement to remove these species once assimilated in the body. |

Annotation: | This project will be focused on study of thermoelectric properties of mechanochemically prepared copper (I) silver selenide. Transition metal chalcogenides, including CuAgSe, are generally known as potential thermoelectric materials, converting waste heat into electricity. Stoichiometric, non-stoichiometric and also doped samples of Cu2-xAgxSe sample series will be synthesized in planetary ball mill by simple, solvent-free method at ambient pressure and temperature. Thermoelectric properties of CuAgSe samples will be investigated. |

Annotation: | As part of the project, various binary nanosulfides of transition metals (Zn, Pb, Sn, Mo, Ag, Ni, Cd) and their composites with a potential mixture in photocatatalytic wastewater treatment will be mechanochemically synthesized. The synthesis will be performed by grinding the octane of the respective metal and the eggshell membrane or thiourea as a source of sulfur. Finally, the photocatalytic and antibacterial activity of the products will be tested. |
