| Annotation: | The central hypothesis of ZERO project is that by real -time
monitoring of Li deposition rate, wetting and/or alloying, and mechanical stress at the SSE/CC interface, we can
optimize and tailor SSBs providing higher capacity and cycling lifetime. This can be achieved by controlling
charge/discharge currents, appropriate alloy-forming interlayers, and managing internal stresses by external loads.
The main aim of ZERO project is to develop optimal alloy-forming interlayers and charging strategies to achieve the high capacity and cycling lifetime of ZESSBs. This will be enabled and connected with the developing and/or
updating methodologies that will facilitate experimental monitoring and a better conceptual understanding of the
growth phenomena involved in the formation of the Li anode in ZESSBs. To this end, we will develop novel
laboratory and synchrotron techniques to explore ZESSB-related phenomena under in operando conditions. |

| Annotation: | The project “Eco-Friendly Surface Modification of Electrode Materials in Deep Eutectic Solvents: An Innovative Strategy for Enhancing Photo- and Electrocatalysts for the Hydrogen Evolution Reaction” is a two-year research project focused on advancing the development of efficient photo- and electrocatalysts for the Hydrogen Evolution Reaction (HER). This research aims to investigate the kinetic and mechanisms of electrodeposition, electrooxidation, and electroless deposition of photo- and electroactive layers on cost-effective substrates using eco-friendly electrolytes, specifically room-temperature deep eutectic solvents (DESs). The ultimate goal is to produce high-performance cathode materials for the eco-friendly production of “green” hydrogen. The project addresses the critical need for sustainable hydrogen production via electrolysis using renewable energy sources.
While the HER is well-studied, the search for cost-effective, abundant, and durable electrode materials with comparable or superior catalytic activity to noble metals remains essential. Noble metals are limited by their cost, availability, durability, and susceptibility to catalyst poisoning. This research project focuses on three main objectives: 1. Investigating the electrooxidation processes of titanium and its alloys in DESs to produce highly organized nanostructured titanium dioxide layers with excellent photocatalytic activity for HER. 2. Studying the electrochemical deposition of nickel, cobalt, Ni-Co alloys, and their composites onto non-noble metal substrates and conductive carbon-based materials to create efficient electrocatalytic and photoelectrocatalytic coatings for HER. 3. Characterizing the electroless deposition of electrocatalysts based on cobalt, nickel, Ni-Co alloys, and platinum group metals onto various substrates to obtain highly efficient electrocatalysts for HER. Each objective involves determining kinetic parameters, such as rate constants and activation energies, and understanding the underlying mechanisms. The catalytic activity of newly developed electrode materials will be evaluated by assessing parameters like hydrogen evolution overpotential and exchange current density in different aqueous solutions.
The project utilizes DESs known for their attractive physicochemical properties, stability, and biodegradability, ensuring an eco-friendly approach.
Methodologically, the project uses advanced techniques including electrochemical methods, spectral analysis (SEM, AFM, TEM, FTIR, Raman spectroscopy, EDS, XRD, and XPS), and chemical analysis (AAS, ICP, XRF) to comprehensively investigate and characterize electrode materials and coatings. Statistical methods will aid in data analysis and interpretation.
The research team embraces multi- and interdisciplinary approaches, open science principles, FAIR data access, and gender equality in research to ensure robust and collaborative scientific progress.
The project's expected outcomes include the development of theories describing design and properties of innovative photo- and electrocatalysts, a diverse and cohesive research team, enhanced research capabilities, and increased visibility for young scientists. Ultimately, this project contributes to advancing sustainable hydrogen production and supports the EU's and SK's commitment to a green hydrogen economy. |

| Annotation: | The NanoGlow project aims to develop i) functional “Trojan horse” hydrogels with embedded photothermal
nanoparticle conjugates, ii) validated in vitro and iii) complemented with state-of-the-art structural and chemical
mapping at the nanoscale. Photothermal, pH-responsive MoOx nanoparticles will be conjugated with tumor-homing RGD peptides and embedded in nontoxic, biodegradable poly-(2-oxazoline)- and bio-sourced Tulipalin A-based
matrices. Near-field nanoscopy, Atomic Force Microscopy Force Spectroscopy, and Confocal Raman Microscopy
of nanoconjugate-hydrogel superstructures and in vitro samples will characterize nanoscale related phenomena
observable at the macroscale. NanoGlow’s unique nano-to-macro approach will provide a basis for the application
of the proposed hybrid structures in the fight against complex and hard-to-treat glioblastomas. |

| Annotation: | The steadily increasing energy consumption calls for renewable technologies that could substitute environmentally detrimental and costly fossil fuels. These technologies must satisfy environmental, economic, and social feasibility criteria. Perovskite-based solar modules show the ability to meet these fundamental requirements. Recently, the power conversion efficiency (PCE) of a single-junction solar cell based on halide perovskite has reached 25.7 % , and the perovskite/silicon tandems over 33 % , greatly outperforming the silicon solar cells efficiencies. Further efficiency improvement is prevented by defects that cause non-radiative recombinations – either through trap-assisted recombination in the active layer or via carrier recombination at the perovskite/transport layer interfaces. This proposal focuses on the defects in halide perovskite and related phenomena that are critical in limiting performance in photovoltaic applications. Furthermore, it aims to develop effective passivation routes to achieve further performance advances. Its innovation potential lies in increasing the efficiency of future photovoltaic applications via addressed investigation of the non-radiative traps at the grain boundary surfaces and interfaces and their efficient passivation. |

| Annotation: | It was found that charge recombination plays a significant role in
restricting the performance of potential perovskite-based applications, which usually happens in the presence of
defect states. It is generally accepted that the perovskite defects are responsible for most of the issues that hinder
the further commercial usage of perovskite-based devices. This indicates that the direction of further efficiency
increase lies in the addressed defects passivation. Therefore, this project focuses on a detailed investigation of
defect-induced nonradiative recombination processes in perovskite films and subsequent passivation of the defect
states. |

| Annotation: | Liver fibrosis occurs as a result of chronic liver damage associated with the accumulation of extracellular matrix proteins. It is the common outcome of various infectious and non-infectious diseases and represents a global health problem resulting from the high global prevalence and limited treatment options. Treatment of liver fibrosis is essential to prevent the development of liver cirrhosis and hepatocellular carcinoma, however, there is no effective pharmaceutical intervention to date for the treatment of this disease. One of the promising but yet barely explored approach to treat the liver fibrosis is offered by the targeted therapy using nanomaterials coated with an antifibrotic drug. In case of inorganic nanomaterials, spherical gold nanomaterials are being investigated for this aim. Interestingly nanomaterials of other shapes (e.g. nanobipyramids) could possess even better diagnostic and therapeutic features due to their unique physical-optical properties. |
