The first objective involves the mechanical activation of metals and chalcogens to produce fine, flaky, or delaminated precursors, which are crucial for optimizing the surface area and reactivity of starting materials. To complement this, we will develop a transferable device capable of monitoring pressure and temperature during planetary milling with subsecond resolution, providing valuable insights into the milling process and allowing for precise control over reaction conditions. Our investigation will also explore how the properties of selected reagents and milling conditions influence the ignition time of MSRs, aiming to elucidate the conditions that favor the formation of binary and ternary metal chalcogenides (MxCy, where M = Ag, Cu, Co, In, Ni and C = S, Se). Furthermore, we seek to identify the primary driving forces behind ball-free MSRs for selected metal chalcogenides, which will be critical for predicting reaction outcomes and improving synthesis strategies. Finally, we will explore the application potential of the synthesized products in electrocatalysis, particularly for hydrogen evolution reactions (HER).

Direct structural and functional connection is created between a bone and the surface of a load-bearing implant after implantation without interfering with soft tissue. Therefore, successful osseointegration is crucial for implants\\&#8217; long-term stability and functionality. In the case of orthopedic scaffolds, surface treatment may improve their osseointegration. Ceramics, particularly bioactive ones (hydroxyapatite, e.g.) can be engineered with specific surface morphologies and porosities that enhance cell attachment and proliferation. Moreover, the unique 3D design of the implant affects load distribution and its mechanical stability. Mimicking the natural anatomy of the bone can also improve biomaterial integration and the healing process. However, in some cases, the body may recognize the implant as a foreign object, triggering an immune response that can lead to chronic inflammation and discomfort. Thus, incorporating drug delivery systems within the implant coating design can provide localized delivery of osteogenic or antimicrobial agents, enhancing bone healing and reducing infection risk. In the opening stage of the project, a novel titanium (Ti6Al4V) alloy implant design will be proposed and the scaffolds will be produced by additive manufacturing using the selective laser melting (SLM) method. Then, different types of ceramic coatings (hydroxyapatite, bredigit, calcium-doped silicates e.g.) will be applied to the material surface using different methods including electrochemical deposition and sol-gel technique. Lastly, ceramics will be enhanced with antibacterial agents (antibiotics, silver, e.g.) to improve its antibacterial effect. Surface morphology, chemical composition, degradation properties, and biological properties of the prepared specimens will be tested and evaluated.<\/span><\/td>\n<\/tr>\n<tr>\n<td>Duration:<\/td>\n<td>1.9.2025 &#8211; 31.12.2028<\/td>\n<\/tr>\n<\/table>\n<table class='project_list'>\n<tr>\n<td colspan='2'>Biocomposite cement with vitamin K for bone regeneration<\/td>\n<\/tr>\n<tr>\n<td colspan='2'>Biokompozitn\u00fd cement s vitam\u00ednom K pre regener\u00e1ciu kost\u00ed<\/td>\n<\/tr>\n<tr>\n<td>Program:<\/td>\n<td>VEGA<\/td>\n<\/tr>\n<tr>\n<td>Project leader:<\/td>\n<td>Ing. \u0160tulajterov\u00e1 Radoslava, PhD.<\/td>\n<\/tr>\n<tr>\n<td><a href=\"javascript:toggle('show3')\">Annotation:<\/a><\/td>\n<td><span id=\"show3\" style=\"display: none;\">The project focuses on the research and development of calcium phosphate cement\/starch\/vitamin K composites with optimized composition.

However, disadvantages are high volatility, hydrophobicity and intense odor which hampers their direct application. Incorporation of essential oils into polymers is an effective method to increase hydrophilicity and stability of system with the simultaneous reducing of volatility.
