Archipelagos - - Bog - Nova Science Publishers Inc - Plusbog.dk

The book begins by examining the Canary Islands and their characteristic orography and regime of winds that affect this archipelago. Investigations were carried out by the authors which allowed for the characterization of the atmospheric corrosion for metals of wide industrial use. Due to its geographical location, the Azores archipelago is one of the perfect places to observe and study the characteristics of atmospheric processes. The remote conditions of the islands allow for the monitoring of greenhouse gases without the influence of local sources of pollution. Consequences of climate change are also discussed. The closing chapter discusses a new paradigm in the sol-gel synthesis, particularly in the synthesis of bioactive glass. In this new approach, the deionized water is replaced by highly ionized and naturally acidified thermal water collected from springs located in Furnas Volcano. Given the potential impact of these waters on the structure and bioactivity of sol-gel bioactive glass, special emphasis is given to their genesis, physicochemical properties and ionic diversity.

Proteomics - - Bog - Nova Science Publishers Inc - Plusbog.dk

Proteomics - - Bog - Nova Science Publishers Inc - Plusbog.dk

This compilation provides a brief overview of proteomic techniques used in acute leukaemia, including the high-throughput reverse phase protein array, which will highlight the importance of measuring proteins. Following this, the authors discuss the molecular mechanism of oseltamivir and the advantages and disadvantages of using it. Proteomics- and transcriptomics-based alternatives to oseltamivir are described as well. Additionally, the most recent research studies aiming to identify biomarkers for the early prediction of spontaneous preterm labour using mass spectrometry-based proteomics are reviewed. In order to understand the mechanisms of efficient degradation of lignocellulosic biomass, a comprehensive analysis of carbohydrate-degrading and metabolic enzymes is required. As such, the authors summarize a proteome analysis of C. cellulovorans cultured with different carbon sources, and provide some insights as to how C. cellulovorans optimises diverse enzymes depending on carbon sources. The concluding chapter focuses on comparative fluorescence gel electrophoresis, which was invented in 2009 and has since then become the prime method for reproducible coordinate assignment in two-dimensional protein polyacrylamide gel electrophoresis.

Photocatalysis on Titania-Coated Electrode-less Discharge Lamps - Hana Abova - Bog - Nova Science Publishers Inc - Plusbog.dk

Photocatalysis on Titania-Coated Electrode-less Discharge Lamps - Hana Abova - Bog - Nova Science Publishers Inc - Plusbog.dk

This book demonstrates outstanding improvement of photo-catalytic degradative efficiency by the coupling of microwave (MW) radiation with the titania-coated electrode-less discharge lamps (EDLs). Titania thin film is used as the photo-catalyst due to its superior characteristics. The EDL as a novel light source generates efficiently UV/Vis radiation when placed into a MW field. Thin nanoporous titania films are prepared by dip-coating of EDL via a sol-gel method using titanium isopropoxide, or titanium n-butoxide, acetylacetone, and a transition metal acetylacetonate.

Bioencapsulation in Silica-Based Nanoporous Sol-Gel Glasses - Farid Menaa - Bog - Nova Science Publishers Inc - Plusbog.dk

Bioencapsulation in Silica-Based Nanoporous Sol-Gel Glasses - Farid Menaa - Bog - Nova Science Publishers Inc - Plusbog.dk

In this book, the authors report the recent results on the influence of different parameters (such as surface hydration, hydrophobicity, solute effects, thermal stability, porosity, macromolecular crowding) on the protein conformation based on the design and the characterisation of nanoporous silica-based materials containing different functional groups (e.g., hydrophobic alkyl, phosphate and fluorinated groups). The enhancement of the protein folding owing the physical properties and microstructure of the host matrix induced by the nature of the functional groups and the siloxane network play a major role on the protein biological activity and therefore to the development efficient bionanodevices such as biocatalysts, sensors, drug delivery systems or implanted devices. This book enlightens the bioapplications of silica-based glasses prepared from functionalised organosilane precursors used to mimic and to understand the different factors that influencing the protein folding process.

Europium III - Paulo S Calefi - Bog - Nova Science Publishers Inc - Plusbog.dk

Europium III - Paulo S Calefi - Bog - Nova Science Publishers Inc - Plusbog.dk

Europium belongs to the lanthanide series of the periodic table. The most important property of this element is its luminescence, which can be defined as emission of light by a material as a consequence of energy absorption. Such property leads to the main use of this element; that is, its application as phosphor, which emits colored light through electroluminescent processes, with potential utilisation in computer and TV displays. Many scientists employ the luminescence spectroscopy of the europium ion to elucidate the structure of natural and synthetic compounds. This book reviews research on the photoluminescence of the europium ion in different materials, prepared by hydrolytic and non-hydrolytic sol-gel methodologies and intercalation in kaolinite.

Phase Formation & Superconductivity in Copper Oxide Based YBCO & Ru-1212 & Ru-1222 Systems Prepared by Sol-Gel & Coprecipitation Techniques - Yeoh Lee

Phase Formation & Superconductivity in Copper Oxide Based YBCO & Ru-1212 & Ru-1222 Systems Prepared by Sol-Gel & Coprecipitation Techniques - Yeoh Lee

The discovery of superconductivity behaviour in ceramic materials based on copper oxide suggests that ceramic can be used as an insulator material. However, superconductivity mechanism-based copper oxides are still seen as mysterious and misunderstood by scientists, even though the search for materials with higher critical temperatures has been ongoing. This effort can be seen from the first discovery of superconductor in the critical temperature of mercury 4.2 K up to the highest critical temperature of 164 K in the copper oxide superconductors Hg-Ba-Ca-Cu-O in 1993. This book discusses the development of high temperature superconductors since the discovery of the first superconductor until now, as well as the basic properties of high temperature superconductor. In addition, it also describes various wet chemical methods in superconductors preparation.

Organic Polymers - - Bog - Nova Science Publishers Inc - Plusbog.dk

Organic Polymers - - Bog - Nova Science Publishers Inc - Plusbog.dk

In this compilation, examples of film polymeric composites based on azobenzene polymers and metallic complexes for use in electro-optical modulators and recording media for polarization holography are considered. It is shown that the information characteristics of the investigated media are mainly influenced by the structure of the azobenzene groups (electron-donor and electron-acceptor substitutes) and by the supramolecular structure of the polymers. Following this, precise analyses of the molecular arrangement of three-dimensional crystals, two-dimensional molecular films, and interfacial particle layers of polyguanamine derivatives with a high refractive index are been performed. It is determined that the high refractive index of the polyguanamine derivatives is not caused by the chemical structure of the molecule, but is based on the packing of molecular chains or the refraction of transmitted light due to the difference in electron density between the crystalline and amorphous regions. In the closing chapter, organic-inorganic hybrid polymers are applied in different fields, including adsorption of metals from aqueous media. In this context, two organic-inorganic hybrid polymers were prepared by sol-gel method, using proportions of 1:1 and 1:3 of the monomer 1-vinylimidazole and the silane agent 3-mercaptopropyl-trimethoxysilane, respectively, in order to evaluate the proportion effect of VI and MPTMS on Hg2+ ions adsorption from an aqueous solution.
