The work of doctoral students under supervision of their tutors is focused either on independent and creative experimental activity or theoretical pursuits. The study is based on a thorough theoretical knowledge of the whole discipline of chemistry. The student acquires this knowledge by completing compulsory optional courses, which are supplemented by the latest information in the given area, and through optional courses gaining experimental technique skills, as well as learning new methods. In addition, the programme contributes to developing the abilities of students to critically evaluate findings gained from literature and pass on these as well as their own findings to the public by means of seminars. Teaching experience is gained by assisting in selected courses for students of bachelor and master programs. An important goal of doctoral studies is also gaining broad scientific view of the discipline, international experience and language skills, which is facilitated by research stays at domestic and foreing partner institutions and by active participation at national and international scientific conferences. During their studies student will learn to prepare manuscripts in English. The ultimate goal of this study is to obtain significant scientific results that can be published in prestigious journals and finally summarize them in a doctoral dissertation thesis. Graduates of this program will be primarily prepared to pursue scientific carries in academic institutions, but they also could be employed in research and development departments of various companies, in medical establishments, and in government institutions.

Dissertation topics

Specialization: Analytical Chemistry

Acoustic Spectroscopy of Laser-Induced Plasma
Supervisor: doc. Mgr. Karel Novotný, Ph.D.

The acoustic signal associated with the plasma formation during the Laser-Induced Breakdown Spectroscopy (LIBS) will be studied. Investigation of the frequency spectrum of the acoustic signal during ablation of various materials as well as study concerning the shot-to-shot evolution of the laser-induced crater morphology and plasma emission lines will be the main topic of this work. The previous results confirm that the acoustic signal is well correlated with the target hardness/density and also can be used as an ablation rate indicator. Acoustic signal provides new information relative to the ablation process that is independent of the LIBS spectrum.

Synthesis and application of composite nanoparticles in bioanalytical chemistry
Supervisor: doc. RNDr. Petr Kubáň, Ph.D.

Nanočástice přináší řadu unikátních vlastností, které nacházejí uplatnění v řadě inovativních metod a protokolů. Není tak náhodou, že využití nanomateriálů patří mezi Národní priority orientovaného výzkumu, experimentálního vývoje a inovací (VaVaI).
Nanočástice mají nezastupitelné místo i v analytické chemii. Jednotlivé analytické aplikace pak kladnou specifické nároky na konkrétní vlastnosti potřebných nanočástic. Těchto vlastností je někdy náročné dosáhnout při použití jediného typu materiálu (tj. prvku či sloučeniny). Tato dizertační práce směřuje na přípravu nanočástic z plasmonických kovů v kombinaci s dalšími materiály tak, aby byly připraveny částice maximálně vhodné pro danou analytickou aplikaci.
Jedním z cílů dizertační práce tak bude příprava nanočástic umožňující selektivní a citlivou detekci peptidických látek pomocí povrchem zesílené Ramanovy spektrometrie. Zde budou připravované částice složené ze stříbra a sorbentu. Druhá část práce bude směřovat na selektivní detekci thiolovaných látek. Zlaté nanočástice (AuNP) nebo konjugované částice AuNP-Fe3O4 s magnetickými vlastnostmi mají obzvláště silnou afinitu k biomolekulám obsahujícím thiol, které se spontánně adsorbují na povrch Au nanočástic. Aplikace AuNP a AuNP-Fe3O4 bude využita pro selektivní extrakci a prekoncentraci biologických thiolů z neinvazivních biologických tekutin (EBC, sliny, pot) s možností automatizace celého procesu.

A DFT study of hybrid silicophosphates reactivity
Supervisor: doc. Mgr. Markéta Munzarová, Dr. rer. nat.

Předložený projekt navazuje na diplomovou práci Mgr. Jakuba Nagyho "Teoretické studium hybridních fosfosilikátových materiálů" obhájenou na Ústavu chemie PřF MU v lednu 2022. Výpočty, které byly v práci provedeny, vedly k vytvoření sady cyklických modelů silikofosfátů s křemíkem v koordinaci 4, 5, nebo 6 s postupnou náhradou několika fosfátových skupin acetáty. Dále ukázaly souvislosti mezi chemickým stíněním centrálního atomu křemíku, úhly mezi vazbami, jichž se centrální křemík účastní, a chemickou identitou substituentů. Hlavní otázkou experimentalistů na počátku celého projektu však bylo pochopení snížené reaktivity silikofosfátů vzhledem k tvorbě hypervalentních struktur, jsou-li některé z fosfátových skupin v reaktantu v koordinaci 4 nahrazeny acetáty. Studium mechanismu reakce čtyřkoordinovaného "čistého" vs. hybridního silikofosfátu s vazebným partnerem bude hlavní náplní předkládaného doktorského projektu. Pro vybranou sadu čtyřkoordinovaných čistých a hybridních silikofosfátů bude metodou DFT modelován povrch reakční potenciální energie, identifikovány tranzitní stavy s dostatečně nízkou energií a jim příslušející produkty. Konečným výstupem předpokládaných publikací bude pochopení zákonitostí mezi identitiou a konformací reaktantu a výškou aktivační bariéry pro příslušnou kondenzační reakci.

Functional metal organic frameworks and supramolecular assemblies
Supervisor: doc. Mgr. Marek Nečas, Ph.D.

The research is focused on the synthesis of new polytopic ligands and their utilization in the construction of functional coordination polymers (porous, luminescent). The attention is given to robust architectures of MOFs, which can be exploited as matrices for crystallization of small molecules (crystalline sponges). Another line of research includes the search for a functional connection between metal complexes and organic macrocycles and molecular clips. Using a rotating anode dual-wavelength X-ray diffractometer, we are able to determine structures even of very tiny crystals and of very complex systems with large unit cells.

Ruthenium and platinum coordination compounds for novel antitumor therapies
Supervisor: prof. RNDr. Radek Marek, Ph.D.

Many transition-metal complexes are known to be biologically active. This applies particularly to coordination compounds containing platinum represented by clinical drugs cisplatin, carboplatin, and oxaliplatin. Highly promising compounds with antimetastatic potential contain ruthenium active core. We are working on the development of novel ruthenium and platinum coordination compounds containing anchors designed for binding with macrocyclic carriers from the family of cyclodextrins, cucurbiturils or calixarenes.
This project includes the synthesis of a series of mono and multinuclear, homo and heteroleptic metallocomplexes containing mono or polydentate ligands possessing hard or soft donor atoms. The molecular and supramolecular structures of compounds are characterized by using modern methods of NMR spectroscopy, ESI-MS, and ITC. Automatic crystallization robotics together with advanced crystallization techniques are employed to grow monocrystals and to reveal further structural details of complexes in the solid state by X-ray diffraction.

    OBJECTIVES: These dissertation projects will explore new routes to porous materials based on metallosilicates. The synthetic procedures will be based on non-hydrolytic sol-gel reactions. Developed procedures will be optimized with respect to maximizing surface area and pore volume and controlling chemical composition and catalytic activity in topical catalytic reactions (e.g. ethanol dehydration, ethanol to butadiene conversion, etc.).
    EXAMPLES of potential student doctoral projects:

    • Synthesis of aluminosilicates for ethanol dehydration
    • Synthesis of metallosilicates for conversion of ethanol to 1,3-butadiene
    • Synthesis of metal nanoparticles deposited on porous supports for ethanol dehydrogenation
    • Synthesis of silicophosphates for ethanol dehydration

    Quantum-mechanical and/or thermodynamic modelling in metallic materials
    Supervisor: doc. Mgr. Jana Pavlů, Ph.D.

    Jedním z možných předmětů práce je počítačové modelování elektronové struktury a stability vybraných fází pomocí metody FLAPW (Full-potential Linearized Augmented Plane Wave) nebo pseudopotenciálového kódu VASP (Vienna Ab initio Simulation Package). Získané informace o elektronové struktuře, energetických, magnetických a mechanických vlastnostech studovaného materiálu budou následně rozšířeny o studium poruch krystalové mříže a jejich vlivu na stabilitu a vlastnosti materiálů. Aktuálně řešené problémy se týkají stability nanokompozitů, hranic zrn a fázových rozhraní.

    Kromě kvantově mechanického modelování je též možné se zabývat semiempirickým termodynamickým modelování fázových rovnovah a fázových diagramů pomocí metody CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry). Toto studium je zaměřeno na systémy obsahující intermetalické fáze, neboť tyto struktury vykazují specifické vlastnosti, které významným způsobem ovlivňují chování technologicky významných materiálů. Na základě znalosti stability intermetalických fází v závislosti na teplotě a složení bude možné předvídat chování studovaných systémů.

    Informace o tvorných teplech vybraných fází vzhledem k standardním stavům čistých složek potřebné pro modelování pomocí metody CALPHAD je možné získat z kvantově-mechanických výpočtů, a proto je možné se v disertační práci věnovat oběma typům výpočtů.

    Pro studium bude vybrána modelová kovová soustava.

    Development of Smart Molecular Capsules
    Supervisor: prof. RNDr. Radek Marek, Ph.D.

    Low solubility, biostability, and inefficient targeting of otherwise highly promising active pharmaceutical ingredients are often the limiting factors for their final approval for clinical use. We are developing a methodology to suppress these deficiencies by introducing a novel family of biocompatible macrocyclic carriers. The work consists of three main tasks: 1) the synthesis of covalent molecular capsules, 2) using these in analytical studies of their supramolecular host-guest interactions with selected drug candidates, and 3) carrying out further synthetic modifications of the capsules in order to fine-tune their affinity, activity, targeting, and release of drugs, which are based on results of complementary biological studies.

    Paramagnetic NMR spectroscopy assisted by DFT calculations: Supramolecular metallocomplexes
    Supervisor: prof. RNDr. Radek Marek, Ph.D.

    Development of novel coordination compounds of transition metals is stimulated by their broad applications in chemical catalysis, material science, and medical treatment or diagnosis. Understanding their chemical properties (stability, reactivity, formation of host-guest complexes) requires their molecular and electronic structure to be known. We use modern methods of NMR spectroscopy to investigate the above-mentioned systems in detail.
    The presence of heavy metal atoms, open-shell character, conformational flexibility, and supramolecular interactions with binding partner must be carefully considered. Thus, the interpretation of NMR experiments requires synergy with various computational tools of quantum chemistry and molecular modelling. The general goal of this study is to apply developed methodology for the structure characterization of new metallocomplexes associated with various cavitands.

    Quantum-mechanical analysis of the influence of crystal lattice defects on the properties of materials
    Supervisor: doc. Mgr. Jana Pavlů, Ph.D.

    Tato práce bude zkoumat nejen materiály s ideální krystalovou strukturou, ale především se bude věnovat systémům obsahujícím strukturní defekty, jako jsou nečistoty, vakance, hranice zrn mezi zrny jedné fáze nebo mezifázové hranice vzniklé mezi dvěma fázemi tvořícími nanokompozity a jejich kombinacím. V případě materiálů obsahujících magnetické prvky (Fe, Ni, Co) bude studován vliv hranic zrn, mezifázových hranic, vakancí a nečistot na magnetické uspořádání. V případě rozhraní bude analyzováno, zda se přidané nečistoty rozpustí v příslušných fázích nebo budou segregovat na rozhraní.

    Pro získání relevantních fyzikálních charakteristik intermetalických fází a jejich rozhraní (atomová konfigurace, magnetické momenty v oblastech rozhraní, energie tvorby rozhraní atd.) bude použit pseudopotenciálový kód VASP (Vienna Ab initio Simulation Package).

    Quantum-mechanical calculations of surface-induced magnetism
    Supervisor: doc. Mgr. Jana Pavlů, Ph.D.

    Povrchy a vnitřní rozhraní patří mezi velice časté planární defekty vyskytující se v krystalických materiálech. Tyto defekty jsou schopny ovlivnit magnetické vlastnosti materiálů, kdy u magnetických materiálů může docházet ke zvýšení jejich magnetického momentu [1] a u materiálů nemagnetických dokonce k indukování magnetického momentu na atomech při povrchu [2,3]. Experimentální studie naznačují, že ke generování magnetického momentu by mohlo docházet u oxidů, jako je HfO2 nebo TiO2 [4]. Bohužel tyto studie neposkytují detailní vysvětlení tohoto jevu na atomární úrovni. Ani není známa termodynamická a mechanická stabilita těchto materiálů. Navrhovaná doktorská práce se bude tudíž soustředit na výpočty chybějících charakteristik povrchů vybraných v souvislosti s magnetismem. Ke studiu budou využity kvantově-mechanické metody.

    The Spectroscopy and Microscopy of Chemical Compounds in Ice within the Environmental and Pharmaceutical Domains
    Supervisor: doc. Mgr. Dominik Heger, Ph.D.

    Compounds on ice: Ice and snow, the solid forms of water, are very interesting reaction media. Organic compounds are mostly expelled from the inside to the surface of ice and to the veins between ice crystals. We study the compounds in these compartments by absorption, emission, microscopy, and reactivity. These compartments differ from the original solution: the concentration of impurities increases, and the amount of available protons changes. Electrical potential is created on the interface between ice and the solution during freezing. The above facts strongly affect the frozen compounds, whether in natural or human-induced freezing. We investigate the spectroscopy, speciation and compartmentation of compounds on ice to describe ice - compounds interactions.
