Annotation:With the steadily increasing energy requirements of portable electronics and electromobility, conventional lithiumion batteries are facing new challenges. In the proposed project, we aim to stabilize the capacity and lifetime of lithium-ion batteries employing ultra-thin interfacial layers prepared by means of atomic layer deposition (ALD). The primary functions of interfacial layers are: i) preventing the dissolution of the cathode materials into electrolyte and ii) stabilizing the cathode morphology during lithiation and de-lithiation. Although the positive effect of ALD fabricated interfacial layers has already been demonstrated, systematic studies are still missing. The main bottleneck of such studies is the identification of appropriate feedback analytical techniques that enable real-time and in-operando insights into the charging/discharging mechanisms on the nanoscale. The conventional electrochemical characterization methods can only provide hints on the ongoing mechanism during degradation processes. Here we propose to utilize in-operando small-angle and wide-angle X-ray scattering (SAXS, WAXS) to track the morphology and phase changes that occur during the charging/discharging of lithium-ion batteries in realtime. The main focus of this project is on the application of real-time SAXS/WAXS studies under laboratory conditions. In these circumstances, extensive, systematic studies of various ALD interfacial layers can be performed.

Tribo2D - Tribological properties of 2D materials and related nanocomposites

Tribologické vlastnosti 2D materiálov a príbuzných nanokompozitov

Duration: 1. 8. 2018 - 30. 6. 2022
Program: APVV
Project leader: Ing. Ťapajna Milan PhD.
Annotation:Tribological effects have been estimated to generate about 23% of the world’s total energy consumption. Lowfriction coating is the most widely applied technology to improve the tribological behaviour, acting as solid lubricants. Many solid lubricating coatings including TiN, TiC, diamond-like C, and graphite are nowadays usedby the industry. Compering to these traditional coatings, 2-dimensional (2D) materials offer some exceptional advantages, such as extremely low friction, wetting transparency, and oxidation resistance. However, deposition of 2D materials in larger scale by industry-friendly equipment is not yet available. Moreover, there has been only limited progress in detail understanding of the mechanical behaviour of 2D materials. Therefore, this project aims to develop existing technologies for deposition of 2D materials and nanocomposites for low friction coating, targeting primarily micrometre (MEMS) as well as centimetre scale (micro-machinery and medical components) applications. We will employ three different techniques for large-scale deposition of emerging (graphene, MoS2, WS2) and new 2D materials (transition metal diselenides) and nanocomposites. We will also focus on development of dedicated adhesion-improving interlayers such as B4C and graphene oxide. Nanotribological studies using friction force microscopy and nanowear analysis will be performed, aiming deeper understanding of the 2D material-substrate interactions. The prepared 2D materials will be also characterized using set of suitable analytical methods in order to gain knowledge on structure-properties relation. The most promising technologies developed at nanoscale will be then transferred to micro- and eventually macroscale and tested. Finally, we will attempt to develop tailored low-friction coatings for selected applications.

NanoCAre - Nanomedical approach to fight pancreatic cancer via targeting tumorassociated carbonic anhydrase IX

Využitie nanomedicíny v boji proti rakovine pankreasu prostredníctvom zacielenia nádorovo-asociovanej karbonickej anhydrázy IX.

Duration: 1. 7. 2021 - 30. 6. 2025
Program: APVV
Project leader: Dr. rer. nat. Šiffalovič Peter DrSc.
Annotation:Pancreatic cancer is a lethal disease with a rising incidence and mortality and it is the fourth leading cause of cancer-related deaths in Europe. The median survival time of pancreatic cancer is 4-6 months after diagnosis, the lowest survival rate of all cancers. Only 20% of diagnosed cases are operable. Photothermal therapy (PTT) has the potential to become a new frontrunner in the fight against pancreatic cancer. This cutting-edge biomedical application relies on the rapid heating of the plasmonic nanoparticles induced by laser light absorption, followed by an increase in the ambient temperature around the nanoparticles. The effect of the localized surface plasmon resonance (LSPR) can be observed only in a special class of nanoparticles. Photothermal therapy results in selective hyperthermia and irreversible damage of the tumor while avoiding damage to healthy tissue. However, the delivery efficiency of plasmonic nanoparticles is often insufficient. It can be increased by a dedicated functionalization of the plasmonic nanoparticles with ligands (antibodies) that selectively recognize the cancer cells. One of the main aims of the proposed project is to increase the delivery efficiency of the plasmonic nanoparticles for PTT by functionalization with antibodies that selectively recognize the tumor in the body. A promising target for functionalized nanoparticles is carbonic anhydrase IX, a hypoxia biomarker associated with an aggressive phenotype. CA IX is expressed in many types of tumors, while being absent from adjacent healthy tissue, making it an ideal highly specific candidate for anti-cancer therapy target. CAIX is abundantly expressed on the surface of pancreatic cancer cells where it correlates with a poor patient outcome. Targeting pancreatic cancer via nanomaterials-based approach combined with anti-CAIX antibody ensures highly selective application of PTT with potential benefits in the clinical environment.

DITIMA - Development of unique TiMg composite dental implant

Vývoj unikátneho TiMg kompozitného zubného implantátu

Duration: 1. 7. 2021 - 30. 6. 2025
Program: APVV
Project leader: Mgr. Švastová Eliška PhD.
Annotation:Dental implants (Dis) become more affordable and sought solution across a globe, the will be in a place for longer periods and a need for maintenance will decrease. Titanium (Ti) and Ti alloys are the most widely utilized materials for production of DI. Even though Ti-based DI are used with a high success rate, two major issues have remained insufficiently resolved: the stress-shielding effect and their insufficient surface bioactivity. That pushes competition, progress and R&D in the related area further and brings a need for novel solutions, approaches and material concepts. The main aim of proposed project is a development of an innovative endosseous biomedical DI fabricated from the unique partially biodegradable Ti - magnesium (Mg) composite material. New DI will minimize the main drawbacks of the contemporary DI, while it maintains the mechanical performance and fatigue endurance of Ti-based references. An advantageous combination of the mechanical, fatigue, corrosion and biological properties of developed DI is owing to a special DI`s design, which reflects and takes advantage of Ti17Mg, the material it will be manufactured from. Ti17Mg is the experimental powder metallurgy material invented by project partners, which selectively exploits the advantages of both biometals. In the project a new DI will be designed and optimized, in order to reflect unique behavior and workability of Ti17Mg. Performance of DI will be assessed and optimized systematically in an environment, which simulates real-life conditions in a human body, including mechanical, fatigue and corrosion testing, and in-vitro and in-vivo biological evaluation using cell culture, small and large animal models. All assays will be carried out in accordance with related ISO specifications. It is anticipated that at the end of the project new innovative high value-added DI is available and pending for testing in a human body. Expectedly TRL 6 will be accomplished at the end of project.
