Glycinium-3-carboxy-4-hydroxybenzenesulfonate (GCHBS),a new organic compound was synthesized and optical quality single crystal was grown by slow evaporation technique. The structure of grown crystal was elucidated by using single crystal X-ray Diffraction studies. The degree of sharpness and crystallinity was found f…
Texture is an important source of information for distinguishing surface properties. We are able to perceive varioustextural properties of surfaces from tactile or visual inputs. However, it is unclear how touch-produced sounds influence thevarious surface texture perceptions. In this study, we examined whether the to…
\n\tSonic metamaterials have important applications in many fields such as noise control, and acoustic communication. Bwand gap and sound-absorbing spectrum are main judgements for the properties of sonic metamaterials. To broaden the resonant band gap and sound-absorbing spectrum, Woodpile structure was introduced in…
CCTO is the dielectric material that possessed giant dielectric constant. The purpose of this study is to investigate the effect of heating and cooling sintering rate on CCTO phase formation, density, microstructures and dielectric properties. The samples were prepared via solid state technique. The raw materials of C…
In the continuously growing field of nanomedicine, nanoparticles have a pre-eminent position. The particle morphology is a defining aspect of their functionality, yet most current characterization techniques possess certain limitations. This work proposes a novel approach to contrast variation in small-angle X-ray sca…
Bio-composite polymer have an important role in many applications. Bio-composite consists of the perfect combination of natural polymers that are biodegradability, least expensive cost and non-toxicity material. The natural polymer combination that have been used in this research are modified cellulose, which is carbo…
Tato práce je zaměřena na reaktivní depozici termochromických vrstev VO2 pomocí vysokovýkonového pulzního magnetronového zdroje HiPIMS. Jsou zde popsány unikátní vlastnosti tohoto oxidu, způsob jeho syntézy s využitím zpětnovazebního řízení RGFC a možnost zvýšení transmitance ve viditelném spektru přidáním antireflexn…
Formation of neural circuits in the brain is sensitive to deprivation of neural activity during the critical period. In the last few decades, the critical period has been studied extensively. These studies are primarily focused on the development of receptive fields in the cortex. Mechanisms regulating the connection…
This thesis is concerned with the solid-state and physicochemical properties of multi-component forms of model systems and active pharmaceutical ingredients, with particular emphasis on cocrystallization; a method that allow formation of multi-component forms for compounds with non-ionizable or weakly ionisable functi…
‘California’ papaya is a relatively new-released papaya cultivar and dominating papaya markets in Indonesia. It has a very short shelf-life with a quickly decrease of fruit qualities. Anthracnose [Colletotrichum gloeosporioides (Penz.) Sacc] is one of its major postharvest disease. Postharvest treatments with a fruit…
Bakalářská práce se zabývá žárovými nástřiky elektrickým obloukem. V teoretické části jsou popsány jednotlivé metody žárových nástřiků jejich charakteristika, princip a využití v praxi. V experimentální části jsou popsány mechanické a chemické vlastnosti aplikova-ných přídavných materiálu. Dále jsou popsány parametry…
Over the last few years, multicomponent nanocomposite coatings, composed of at least two different phases, have become of great scientific and technological interest because of their outstanding physical and chemical properties.Special interest has been recently devoted to TiAlN coatings due to their attractive mechan…
Revestimentos de zinco obtidos por imersão a quente têm sido amplamente utilizados em estruturas expostas em solos, águas naturais e atmosfericamente, devido a excelente resistência em meios de baixa agressividade. Nessas aplicações, as arestas de corte ficam expostas e estão mais susceptíveis à corrosão. Objetivando…

This thesis presents in situ studies on the active states of manganite water oxidation catalysts in water vapor. The study in chapter 2 probes the surface electronics of the strongly correlated Pr1-xCaxMnO3 (0<x<0.8) by in situ X-ray absorption and photoemission spectroscopy (XANES, XPS). Chapter 3 presents an environ…
De nos jours, des solutions alternatives et durables sont proposées en remplacement des énergies fossiles. L’hydrogène, qui constitue une source énergétique d’avenir, est produit seulement à (4%) par électrolyse et essentiellement par reformage de combustibles fossiles (95%) (IFP-institut français de pétrole). Une tec…
