    This diploma thesis focuses on comparison of thermo-oxidative and chemical stability of metal complexes with humic acids. Three elements representing the group of heavy metals were selected for these experiments (cobalt, copper, nickel). The utilized humic acid was extracted from South-Moravian lignite. Differently concentrated solutions of metals were used for complexes preparation, in order to observe the influence of their initial concentration on both studied stabilities of prepared complexes. Chemical stability of metal complexes was assessed in term of metal ions release from the humic acid structure into two different extraction agents (HCl, MgCl2). Thermo-oxidative behaviour was investigated employing methods of thermal analysis: differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) in particular. The results of this work bring deeper insight into the realm of metal interaction with the humified part of soil organic matter; and at the same time try to shed light on the fate of metal pollutants in the environment and help in the desirable knowledge of treatments such as soil decontamination and remediation. Tato diplomová práce je zaměřena na porovnání termo-oxidační a chemické stability kovových komplexů huminových kyselin. Pro tyto experimenty byly vybrány tři prvky reprezentující skupinu těžkých kovů (kobalt, měď a nikl). Použitá huminová kyselina byla extrahována z Jihomoravského lignitu. Pro přípravu komplexů byly využito různě koncentrovaných roztoků kovů, aby bylo možné pozorovat vliv jejich počáteční koncentrace na obě studované stability připravených komplexů. Chemická stabilita kovových komplexů byla posuzována z hlediska uvolňování kovových iontů ze struktury huminové kyseliny do dvou různých extrakčních činidel (HCl, MgCl2). Termo-oxidační chování bylo zkoumáno pomocí technik termické analýzy: diferenční kompenzační kalorimetrie (DSC) a zejména termogravimetrické analýzy (TGA). Výsledky této práce přinášejí hlubší poznatky o problematice interakce kovů s humifikovanou částí půdní organické hmoty, využitelné k osvětlení problematiky kovových polutantů v životním prostředí a prohloubení žádoucích znalostí procedur jako jsou dekontaminace půdy a remediace.

    Diploma thesis deals with grafting of maleic anhydride and itaconic anhydride onto the poly(lactic acid) (PLA). The dependence of conversion on the various molar ratios of monomer to initiator was observed on the modified poly(lactic acid) at the temperatures 180 °C and 200 °C. The amount of grafted monomer was determined due to the acido-basic titration and due to the FT-IR spectroscopy. Effect of grafting value on the crystallinity modified PLA was determined by using differential scanning calorimetry, DSC. Degradation of PLA was observed orientation due to the melting flow index, MFI. Diplomová práce se zabývá roubováním maleinanhydridu a anhydridu kyseliny itakonové na kyselinu poly(mléčnou) (PLA). U modifikované kyseliny poly(mléčné) byla sledována závislost konverze monomerů na různých molárních poměrech monomer/iniciátor při teplotách 180°C a 200°C. Množství naroubovaného monomeru bylo stanovováno acidobazickou titrací a pomocí FT-IR spektroskopií. Vliv stupně naroubování na krystalinitu modifikované PLA byl zjišťován pomocí diferenční kompenzační kalorimetrie, DSC. Degradace PLA byla orientačně pozorována pomocí indexu toku taveniny, MFI. A

    Epidemiological studies have shown the effect of plant-derived food consumption in the prevention of a wide range of diseases. The natural antioxidants present in these foods, among which polyphenols are very relevant, may be responsible for this health-promoting activity. The aim of this bachelor thesis is to submit evidence in the interaction of certain polyphenols with the genetic material through different signaling mechanisms, especially regarding the stabilization of the non-canonical DNA structure G-quadruplex and therefore point out the most selective substance to inhibit biochemical processes. Furthermore, the thesis includes detailed information that might help understand how polyphenol compounds can be attached to the DNA through epigenetic mechanisms and G4 structures, and which factors may affect the efficiency of these. Different experiments, by biological and experimental repetition, were used to corroborate the interaction between the compounds and DNA. Epidemiologické studie prokázaly vliv konzumace rostlinných potravin v prevenci široké škály nemocí. Přírodní antioxidanty přítomné v těchto potravinách, mezi nimiž jsou velmi důležité polyfenoly, mohou být zodpovědné za tuto činnost podporující zdraví. Cílem bakalářské práce je ukázat interakci určitých polyfenolů s genetickým materiálem prostřednictvím různých signálních mechanismů, zejména pokud jde o stabilizaci nekanonické struktury DNA G-kvadruplex a poukázat tak na nejselektivnější látku pro inhibici biochemických procesy. Dále práce obsahuje podrobné informace, které mohou pomoci pochopit, jak mohou polyfenolové sloučeniny interagovat s DNA prostřednictvím epigenetických mechanismů a G4 struktur, a které faktory mohou ovlivnit jejich účinnost. Různé experimenty, biologickým a experimentálním opakováním, byly použity k potvrzení interakce mezi sloučeninami a DNA. B

    Authors: Zajacová, Lucia;

    With the worsening of global atmospheric conditions, the occurrence of respiratory diseases is on the rise, necessitating the development of more efficient devices. Among these devices, medical nebulizers are frequently used for inhalation therapy. While their usability has been repeatedly tested and confirmed, ongoing improvements are desired. This thesis aims to explore existing studies and information to design an experimental setup for evaluating medical nebulizers. The thesis incorporates the utilization of an idealized mechanical upper-airway Alberta model, a breathing simulator xPULM, and an optical aerosol spectrometer PALAS Promo 2000 in combination with the Wellas sensor 2200. Subsequently, it outlines the design of connections between the utilized components and the planning of measurement methods for accurate evaluation. The employed methods provide valuable insights into the characteristics of aerosols produced by the tested nebulizers. Starting from characterization parameters such as nebulizer aerosol output and output rate, residual volume, particle size, and particle size distribution, the evaluation progresses to assessing deposition and establishing the nebulizer efficiency in delivering aerosol particles to different regions of the respiratory tract. S narastajúcimi problémami v globálnych atmosférických podmienkach stúpa aj výskyt respiračných ochorení a s ním súvisí aj nárast dopytu po efektívnejších zariadeniach na ich liečbu. Medzi takéto zariadenia patrí aj medicínsky nebulizér, ktorý sa často využíva pri inhalačnej terapii. Aj keď bola jeho účinnosť už mnohokrát overená, stále existuje potreba ďalšieho výskumu a vylepšení. Táto práca sa snaží využiť dostupné štúdie a informácie na vytvorenie experimentálneho prostredia na hodnotenie medicínskych nebulizérov. Obsahuje využitie idealizovaného mechanického modelu horných dýchacích ciest Alberta, dýchacieho simulátora xPULM a optického aerosólového spektrometra PALAS Promo 2000 v kombinácii so senzorom Wellas 2200. Následne sa zameriava na návrh spojení medzi týmito komponentmi a plánovanie metód merania pre presnejšie vyhodnotenie. Tieto metódy poskytujú cenné poznatky o charakteristikách aerosólov produkovaných testovanými nebulizérmi. Výsledkom sú mnohé charakteristické parametre, ako je výstup aerosólu z nebulizéra, jeho rýchlosť, zvyškový objem, veľkosť častíc a ich distribúcia. Hodnotenie sa ďalej sústreďuje na usadenie častíc a stanovenie účinnosti nebulizéra pri dodávaní aerosólových častíc do rôznych častí dýchacieho traktu. B

    In this master’s thesis, we focused on the study and preparation of nano-structures on graphene by local anodic oxidation. Our attention was put on the isolating capabilities of oxidized graphene, which was studied by surface electric potential mapping, using Kelvin probe force microscopy, with simultaneous transport measurement. The obtained results indicate the doubling of resistance by line interruption oxidation. Finally, nanoconstriction of micrometer dimensions was fabricated and studied under different relative humidities, in the range of 3% to 60%. V tejto diplomovej práci sme sa zamerali na štúdiu a prípravu nano-štruktúr na graféne pomocou lokálnej anodickej oxidácie. Naša pozornosť bola venovaná izolačným schopnostiam oxidovaného grafénu, ktorý bol študovaný pomocou mapovania povrchového napätia, využívaním sondovej mikroskopie Kelvinovej sily, a súčasným meraním toku nosičov nábojov. Získané výsledky poukazujú na zdvojnásobnenie odporu pri čiarovom oxidovom prerušení. Ku koncu, nano-zúženie s mikrometrovými rozmermi bolo vyrobené a študované pod rôznymi vlhkosťami, v rozmedzí 3% až 60%. B

    Authors: Ligmajer, Filip;

    Plasmonics – the scientific discipline dealing with interaction between light and metallic materials – when coupled with nanotechnology, offers unprecedented possibilities for light control and utilization. The outcome of this combination can be, for example, focusing of light below the diffraction limit, enhancement of emission or absorption of quantum emitters, or extremely sensitive detection of molecules. This thesis deals with possibilities how to utilize plasmonics for flat optical components, so-called metasurfaces, and for photocatalytic applications based on plasmonically generated electrons with high energy, so-called hot electrons. First, the fundamentals of plasmonics are explained and an overview of its most notable applications is provided. Then, three studies are presented, which cover the use of plasmonic nanostructures for the control of light polarization and phase, for creation of dynamically tunable metasurfaces, and for photo-electrochemistry with hot electrons. The common principle of these studies is the use of advanced – or within these fields uncommon – materials, like, for example, vanadium dioxide or transition metal dichalcogenides. Plazmonika, tedy vědní obor zabývající se interakcí světla s kovovými materiály, nabízí ve spojení s nanotechnologiemi nezvyklé možnosti, jak světlo ovládat a využívat. Výsledkem tohoto spojení může být například zaostřování světla pod difrakční limit, zesilování emise nebo absorbce kvantových zářičů, či extrémně citlivá detekce molekul. Tato práce se zabývá zejména možnostmi využití plazmoniky pro vývoj plošných optických prvků, tzv. metapovrchů, a pro fotokatalytické aplikace založené na plazmonicky generovaných elektronech s vysokou energií, tzv. horkých elektronech. Nejprve jsou vysvětleny teoretické základy plazmoniky a je poskytnut přehled jejích nejvýznamnějších aplikací. Poté jsou představeny tři studie zabývající se využitím plazmonických nanostruktur pro ovládání fáze a polarizace světla, pro vytváření dynamicky laditelných metapovrchů, a pro foto-elektrochemii s horkými elektrony. Společným prvkem těchto studií je pak používání pokročilých, resp. v rámci těchto oblastí netradičních, materiálů, jako např. oxidu vanadičitého nebo dichalkogenidů přechodných kovů. P

    This diploma thesis focuses on comparison of thermo-oxidative and chemical stability of metal complexes with humic acids. Three elements representing the group of heavy metals were selected for these experiments (cobalt, copper, nickel). The utilized humic acid was extracted from South-Moravian lignite. Differently concentrated solutions of metals were used for complexes preparation, in order to observe the influence of their initial concentration on both studied stabilities of prepared complexes. Chemical stability of metal complexes was assessed in term of metal ions release from the humic acid structure into two different extraction agents (HCl, MgCl2). Thermo-oxidative behaviour was investigated employing methods of thermal analysis: differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) in particular. The results of this work bring deeper insight into the realm of metal interaction with the humified part of soil organic matter; and at the same time try to shed light on the fate of metal pollutants in the environment and help in the desirable knowledge of treatments such as soil decontamination and remediation. Tato diplomová práce je zaměřena na porovnání termo-oxidační a chemické stability kovových komplexů huminových kyselin. Pro tyto experimenty byly vybrány tři prvky reprezentující skupinu těžkých kovů (kobalt, měď a nikl). Použitá huminová kyselina byla extrahována z Jihomoravského lignitu. Pro přípravu komplexů byly využito různě koncentrovaných roztoků kovů, aby bylo možné pozorovat vliv jejich počáteční koncentrace na obě studované stability připravených komplexů. Chemická stabilita kovových komplexů byla posuzována z hlediska uvolňování kovových iontů ze struktury huminové kyseliny do dvou různých extrakčních činidel (HCl, MgCl2). Termo-oxidační chování bylo zkoumáno pomocí technik termické analýzy: diferenční kompenzační kalorimetrie (DSC) a zejména termogravimetrické analýzy (TGA). Výsledky této práce přinášejí hlubší poznatky o problematice interakce kovů s humifikovanou částí půdní organické hmoty, využitelné k osvětlení problematiky kovových polutantů v životním prostředí a prohloubení žádoucích znalostí procedur jako jsou dekontaminace půdy a remediace.

    Diploma thesis deals with grafting of maleic anhydride and itaconic anhydride onto the poly(lactic acid) (PLA). The dependence of conversion on the various molar ratios of monomer to initiator was observed on the modified poly(lactic acid) at the temperatures 180 °C and 200 °C. The amount of grafted monomer was determined due to the acido-basic titration and due to the FT-IR spectroscopy. Effect of grafting value on the crystallinity modified PLA was determined by using differential scanning calorimetry, DSC. Degradation of PLA was observed orientation due to the melting flow index, MFI. Diplomová práce se zabývá roubováním maleinanhydridu a anhydridu kyseliny itakonové na kyselinu poly(mléčnou) (PLA). U modifikované kyseliny poly(mléčné) byla sledována závislost konverze monomerů na různých molárních poměrech monomer/iniciátor při teplotách 180°C a 200°C. Množství naroubovaného monomeru bylo stanovováno acidobazickou titrací a pomocí FT-IR spektroskopií. Vliv stupně naroubování na krystalinitu modifikované PLA byl zjišťován pomocí diferenční kompenzační kalorimetrie, DSC. Degradace PLA byla orientačně pozorována pomocí indexu toku taveniny, MFI. A

    Epidemiological studies have shown the effect of plant-derived food consumption in the prevention of a wide range of diseases. The natural antioxidants present in these foods, among which polyphenols are very relevant, may be responsible for this health-promoting activity. The aim of this bachelor thesis is to submit evidence in the interaction of certain polyphenols with the genetic material through different signaling mechanisms, especially regarding the stabilization of the non-canonical DNA structure G-quadruplex and therefore point out the most selective substance to inhibit biochemical processes. Furthermore, the thesis includes detailed information that might help understand how polyphenol compounds can be attached to the DNA through epigenetic mechanisms and G4 structures, and which factors may affect the efficiency of these. Different experiments, by biological and experimental repetition, were used to corroborate the interaction between the compounds and DNA. Epidemiologické studie prokázaly vliv konzumace rostlinných potravin v prevenci široké škály nemocí. Přírodní antioxidanty přítomné v těchto potravinách, mezi nimiž jsou velmi důležité polyfenoly, mohou být zodpovědné za tuto činnost podporující zdraví. Cílem bakalářské práce je ukázat interakci určitých polyfenolů s genetickým materiálem prostřednictvím různých signálních mechanismů, zejména pokud jde o stabilizaci nekanonické struktury DNA G-kvadruplex a poukázat tak na nejselektivnější látku pro inhibici biochemických procesy. Dále práce obsahuje podrobné informace, které mohou pomoci pochopit, jak mohou polyfenolové sloučeniny interagovat s DNA prostřednictvím epigenetických mechanismů a G4 struktur, a které faktory mohou ovlivnit jejich účinnost. Různé experimenty, biologickým a experimentálním opakováním, byly použity k potvrzení interakce mezi sloučeninami a DNA. B

    Authors: Zajacová, Lucia;

    With the worsening of global atmospheric conditions, the occurrence of respiratory diseases is on the rise, necessitating the development of more efficient devices. Among these devices, medical nebulizers are frequently used for inhalation therapy. While their usability has been repeatedly tested and confirmed, ongoing improvements are desired. This thesis aims to explore existing studies and information to design an experimental setup for evaluating medical nebulizers. The thesis incorporates the utilization of an idealized mechanical upper-airway Alberta model, a breathing simulator xPULM, and an optical aerosol spectrometer PALAS Promo 2000 in combination with the Wellas sensor 2200. Subsequently, it outlines the design of connections between the utilized components and the planning of measurement methods for accurate evaluation. The employed methods provide valuable insights into the characteristics of aerosols produced by the tested nebulizers. Starting from characterization parameters such as nebulizer aerosol output and output rate, residual volume, particle size, and particle size distribution, the evaluation progresses to assessing deposition and establishing the nebulizer efficiency in delivering aerosol particles to different regions of the respiratory tract. S narastajúcimi problémami v globálnych atmosférických podmienkach stúpa aj výskyt respiračných ochorení a s ním súvisí aj nárast dopytu po efektívnejších zariadeniach na ich liečbu. Medzi takéto zariadenia patrí aj medicínsky nebulizér, ktorý sa často využíva pri inhalačnej terapii. Aj keď bola jeho účinnosť už mnohokrát overená, stále existuje potreba ďalšieho výskumu a vylepšení. Táto práca sa snaží využiť dostupné štúdie a informácie na vytvorenie experimentálneho prostredia na hodnotenie medicínskych nebulizérov. Obsahuje využitie idealizovaného mechanického modelu horných dýchacích ciest Alberta, dýchacieho simulátora xPULM a optického aerosólového spektrometra PALAS Promo 2000 v kombinácii so senzorom Wellas 2200. Následne sa zameriava na návrh spojení medzi týmito komponentmi a plánovanie metód merania pre presnejšie vyhodnotenie. Tieto metódy poskytujú cenné poznatky o charakteristikách aerosólov produkovaných testovanými nebulizérmi. Výsledkom sú mnohé charakteristické parametre, ako je výstup aerosólu z nebulizéra, jeho rýchlosť, zvyškový objem, veľkosť častíc a ich distribúcia. Hodnotenie sa ďalej sústreďuje na usadenie častíc a stanovenie účinnosti nebulizéra pri dodávaní aerosólových častíc do rôznych častí dýchacieho traktu. B

    In this master’s thesis, we focused on the study and preparation of nano-structures on graphene by local anodic oxidation. Our attention was put on the isolating capabilities of oxidized graphene, which was studied by surface electric potential mapping, using Kelvin probe force microscopy, with simultaneous transport measurement. The obtained results indicate the doubling of resistance by line interruption oxidation. Finally, nanoconstriction of micrometer dimensions was fabricated and studied under different relative humidities, in the range of 3% to 60%. V tejto diplomovej práci sme sa zamerali na štúdiu a prípravu nano-štruktúr na graféne pomocou lokálnej anodickej oxidácie. Naša pozornosť bola venovaná izolačným schopnostiam oxidovaného grafénu, ktorý bol študovaný pomocou mapovania povrchového napätia, využívaním sondovej mikroskopie Kelvinovej sily, a súčasným meraním toku nosičov nábojov. Získané výsledky poukazujú na zdvojnásobnenie odporu pri čiarovom oxidovom prerušení.
