| Annotation: | The AFM-IMASS project focuses on imaging and manipulation of surfaces and nanostructures on them using
local atomic-scale SPM methods. For imaging the AFM and to a lesser extent also STM methods will be used.
For atomic manipulation the AFM methods will be used and for manipulation of electronic charge the KPFM
methods. All experiments will be backed up by computer simulations using mainly methods of density functional
theory and, for correlated systems, by correlated electronic structure methods, QMC in particular. In order to
achieve these objectives we will use the well-proven international consortium which in the last 5 years has
generated several top results published in journals with highest impact factors (Nat. Phys., Nat. Commun., Nano
Lett., ACS Nano, J. Am. Chem. Soc.). In addition to the Inst. of Physics SAS (group of Prof. Stich, computer
modeling and simulation), this consortium consists of Dept. of Appl. Physics, Osaka University (prof. Sugawara
and prof. Li, sample preparation and non-contact AFM/KPFM experiments), Dept. Appl. Phys. University
Giessen (Prof. Schirmeisen, nanotribology experiments), and King's college London (prof. Kantorovich, theory
and simulation). For the purpose of the AFM-IMASS project this consortium will be extended by Inst. of Physics CAS (Prof. Jelinek, AFM/KPFM of correlated systems). In line with that we envisage three principal research
directions: 1) Transition metal oxide surfaces with focus on their catalytic properties, 2) Organometallic materials
and polymers and their electronic properties: 1D and 2D ferrocene, and 3) Nanotribology with focus on structural
superlubricity. Scientific objectives will be complemented by 4) Educational and public outreach targeting young
generation. Objective of the current AFM-IMASS project will be top internationally competitive results with the
ambition of publishing them in the journals with highest impact factors- part of the results in journals with impact
factors >10. |

| Annotation: | We will deal with the formation of theories describing the forecasts of exchange rate developments in the financial markets as well as the dynamics of stock market developments based on strings theory. We want to develop a theory describing the physical properties of graphene, where the superconductor could by created using
topological defects. We will try to extend our work for Weyl semimetals which have unique transport properties and surface state, and in some respect are really 3D analogs of graphene. We will also apply modern methods of mathematical physics in biology for investigation of electron transfer in solar systems and for use of supersymmetry in living organisms to analyze trash DNA, i. e., not active DNA in biological systems. Finally we want work also on the large-scaled systems and try to explain some cosmological question as the anisotropies presented at early stages of the universe formation and the presence of Dark Energy responsible for the accelerated expansion of the universe. |

Dr. Rer. Nat. Šiffalovič Peter PhD. |
| Annotation: | This project is devoted to our continuous effort aimed at the diabetes treatment by transplanted insulin-producing
cells that are immunoprotected from the host immune system by a semipermeable polymer membrane. This
membrane is in the form of a hydrogel microcapsule formed by the polyelectrolyte complexation of polyanions,
the sodium alginate (SA) and sodium cellulose sulfate (SCS) with the polycation poly(methylene-co-
cyanoguanidine), (PMCG). Over the past two decades we have accumulated important knowledge showing that
this type of microcapsule (acronym PMCG), belongs to the family of microcapsules with a promise to reach the
phase of clinical trials. There are two principal advantages of this microcapsule: (1) it exhibits biocompatibility
after intraperitoneal implantation to various animal models, including the pre-clinical model of non-human
primates (NHP), (2) it affords a unique ability to tailor the physico-chemical properties in correlation with in vivo
performance that is not possible for other encapsulation systems. The MICROPAN project aims at the first
systematic investigation for the microencapsulation system of the correlation between polymer selection, encapsulation conditions, microcapsule properties and in vivo performance. This is thanks to the availability of in-
house synthesized SCS and PMCG polymers used instead of commercial polymers with inconsistent
characteristics. The expected project outcome will be the library of microcapsules of predicted performance in
vivo in the immunocompetent mice with the proposal to test selected microcapsules in NHPs that will be planned
outside of MICROPAN project. This project will enhance our understanding of the mechanism of microcapsule
formation by polyelectrolyte complexation and, hence, will contribute to the future rational designs of
microcapsules for immunoprotection of transplanted cells. |

| Program: |

| Project leader: |
RNDr. Mrkývková Naďa PhD. |
| Annotation: | The van der Waals heterostructures (vdWHs) are newly discovered physical structures that consist of several
two-dimensional (2D) atomic layers held together by weak van der Waals forces. The vdWHs show unique
functionalities that are not accessible in their three-dimensional counterparts. This project is focused on the
investigation of the hybrid vdWHs (hybrid refers to the fact that at least one of the layers is organic) with large
application potential in organic electronics and optoelectronics. In particular, we will investigate the growth
kinetics, molecular orientation, structure and lattice parameters of organic thin films deposited on 2D substrates.
The proposed research will address fundamental questions of the molecular thin film growth processes with
particular emphasis on time-resolved in-situ experiments. The novelty of this project resides in the use of new
and intriguing 2D materials as the substrates for the growth of organic molecular films and in a detailed
investigation of this growth process in order to tailor preparation of novel hybrid vdWHs with specific properties.
We will use 2D substrates with different electronic properties, namely the semimetal graphene and the
semiconducting MoS2 thin films, which both have strong application potential in nowadays electronics.
Regarding the organic molecules, we will concentrate on those possessing the properties beneficial for
optoelectronics, such as absorption in the visible spectrum range, good electric conductivity and capability of self-assembly. We will start with pentacene and TzTz-based small molecules. We believe that such basic
research is highly relevant for further development of enhanced organic electronic applications such as organic
light emitting diodes, organic field effect transistors and organic solar cells. |

| In situ growth process and controllable preparation of perovskite monolayer films |
| In situ monitorovanie rastu a riadená príprava monovrstiev perovskitov |
| Program: |

| Project leader: |
Dr. Rer. Nat. Šiffalovič Peter PhD. |
| Annotation: | Metal halide perovskites are an exciting class of materials that possess many of the attributes desirable for optoelectronic applications, with certified power-conversion efficiencies of perovskite-based photovoltaics reaching 23%. Photoluminescence quantum efficiency of thin films used in highly efficient devices is still low (~1%), which is mainly consistent with sizable density of sub-gap trap states that act as non-radiative recombination centers. In order for a solar cell to reach its theoretical performance limits, luminescence should be maximized with all non-radiative recombination eliminated. The conventional perovskite films prepared by solution process are usually composed of nanoscale grains so that there are a number of boundaries in the film. Correspondingly, a perovskite monolayer with single crystal cross-section profile is considered to be the desired active layer. The characteristics of the monolayer film are very close to that of the single crystal film. However, how to prepare a monolayer perovskites film with single crystal cross-section profile for solar cells is still a big challenge. The primary project’s objective is to identify the key mechanisms governing the formation of perovskite thin films during solution fabrication process. Accordingly, systematic understanding of perovskite crystals growth process is highly required and will be sorted out by real-time and in-situ GI-WAXS/SAXS complemented by real-time photoluminescence. The ex-situ energy-resolved electrochemical impedance spectroscopy of trap states in bandgap will be employed to elucidate the relationship between the electronic and structural properties of perovskite thin films. The principal aims of this joint research proposal are focused on understanding of growth mechanism of the perovskites, which will enable controllable fabrication of perovskite monolayer films for high efficiency solar cells. |

| Annotation: | The aim of the research is to gain a new knowledge about of the use of various combinations of nanoparticles and superhydrophobic particles with essential oils in order to inhibite the biodeterioration of traditional as and modern building materials. Antimicrobial effects of selected essential oils with nanoparticles and superhydrophobic particles on natural materials and modern building materials, such as wood (whitewood, pine, etc.), travertine, granite, sandstone, plastics and ceramics to reducing or completely suppressing microbiological
damage will be evaluated. Nanoparticles and superhydrophobic particles (SHPs) should increase the antimicrobial effect of essential oils by formation of hydrophobic barrier and thereby inhibit the growth of
microorganisms. |

| Annotation: | This project aims to bring the paradigm of quantum technologies one step further by consolidating an information-processing framework for higher-order quantum structures. The goal is to extend mathematical description of quantum processes with indefinite causal order to include all possible experimental setups as well as all similar frameworks (higher order maps, process matrices, …). The project starts by investigation of limitations and complexity of such higher order quantum computation. The second objective is to study how these structures can be quantumly programed (controlled) and to develop methods for detecting coherence and causal order superposition in multi-time quantum processes. |

| Annotation: | The project is focused on the research of advanced organometallic perovskite solar cells (PSCs) with the
interfaces modified by 2-dimensional (2D) nanomaterials to achieve improved functionality. In particular,
procedures for incorporation of 2D nanosheets of graphene, graphene oxide and MoS2 will be developed and
optimized in terms of basic electrical parameters such as open-circuit voltage, short-circuit current, filling factor
and power conversion efficiency. Effect of 2D nanomaterials on the crystal and electronic structure of perovskite
will be systematically analyzed. Here, original knowledge on the correlation between the interface quality,
electronic structure and properties of electron transport is expected. The issue of stability enhancement of PSCs
will be addressed separately. The project results will allow tailored preparation of PSCs with enhanced stability
and with direct impact on practical applications. |

Doc. Mgr. Ziman Mário PhD. |
| Annotation: | Future quantum technologies are aiming to enhance our computational power, secure our communication, but also increase precision of our detection devices (from detectors of gravitational waves to medicine diagnostics methods). The effort of researchers included in this project is focused on optimisation of theoretical proposals, also by taking into account more realistic models reflecting the situations outside the laboratories. Our project joins the second quantum revolution on the side of theory, while aiming at mid-term quantum technology applications. We will develop novel tools and methods for improving the performance of quantum measurement, simulation and optimization devices. In particular, we aim to investigate the mathematical structure of quantum information resources in order to utilize them in novel and efficient quantum metrology applications and quantum simulations. The planned analysis of higher-order quantum structures and related optimal information processing is uncovering new quantum resouces (e.g. quantum causality, memory) that has potential to boost qualitatively the performance of quantum computation and communication technologies. Our plans to optimize tensor network algorithms by using the structure of interactions (space-time) are definitely enlarging our chances for efficient quantum simulations of physically relevant quantum many-body systems. Project tasks are divided into three workpackages aiming to optimize quantum structures, develop optimal higher-order quantum information processing and optimisation of tensor network algorithms. |

Ing. Ivančo Ján DrSc. |
| Annotation: | Clinical studies have identified hundreds of different volatile organic compounds (VOCs) present in exhaled air of a human at concentrations in the order of ppm (10-6) or only ppb (10-9) and lower. Some VOCs are recognized as bio-markers of metabolic and physiological processes and potentially allow non-invasive health examination.
For example, a healthy person has concentration of acetone vapors < 0.7 ppm, >1.7 ppm indicates a diabetes patients [1]. A sub-ppm acetone vapours sensor would allow the construction of a personal tester.
The focus of the project will be a research of tungsten trioxide layers for a chemoresistive acetone sensor operating at hundred ppb. We will focus on the triclinic crystallographic phase of WO3, in which a high response to acetone adsorption has been observed. We will develop the preparation of the WO3 nanocrystalline layers with the maximum triclinic phase content, and study its effect on the sensory response and explore other WO3-based systems to increase sensing response.
