Scientific Essay from the year 2015 in the subject Chemistry - Other, , language: English, abstract: The present study investigates the oxidative de-hydrogenation of propane-butane (C3-C4) fraction over mono (Cr, Mo) and bi-metal (Cr-Mo) loaded MCM–41catalysts. The catalysts were prepared by sequential impregnation method at 500oC calcination temperature. Experiments were performed by feeding C3-C4 fraction and CO2 into a continuous flow quartz reactor at atmospheric pressure (P = 1 atm.),...

Research Paper (postgraduate) from the year 2015 in the subject Chemistry - Organic Chemistry, , language: English, abstract: The present study investigates the oxidative dehydrogenation of propane-butane (C3–C4) fraction over mono (Cr or Mo) and bi-metal (Cr-Mo) loaded SiO2 catalysts. The catalysts were prepared by sequential impregnation method at 500oC calcination temperature. Experiments were performed by feeding C3–C4 fraction, oxygen, nitrogen, and steam into a continuous flow quartz...

Teaches and enables students to build confidence in drawing and manipulating curly arrows, a fundamental skill for all organic chemistsThis book is an interactive approach to learning about chemistry of the carbonyl group—inviting students to work through its pages with pencil and paper in hand. It educates with the belief that the most effective way to learn is by practice and interaction. With this in mind, the reader is asked to predict what would happen under a...

Almost all galaxies host in their center a supermassive black hole of mass between a million and tens of billions solar masses. Supermassive black holes grow in symbiosis with their host galaxies across the Hubble time, occasionally accreting surround matter, giving rise to an Active Galactic Nuclei (AGN). This book gives a general review of our current knowledge of AGN, powered by supermassive black holes: how they are fueled by gas (or stars) and what problems are encountered; how can we...

Nanomaterials via Single-Source Precursors: Synthesis, Processing and Applications presents recent results and overviews of synthesis, processing, characterization and applications of advanced materials for energy, electronics, biomedicine, sensors and aerospace. A variety of processing methods (vapor, liquid and solid-state) are covered, along with materials, including metals, oxides, semiconductor, sulfides, selenides, nitrides, and carbon-based materials. Production of quantum dots, nan...

This book consists of a number of papers regarding the thermodynamics and structure of multicomponent systems that we have published during the last decade. Even though they involve different topics and different systems, they have something in common which can be considered as the “signature” of the present book. First, these papers are concerned with “difficult” or very nonideal systems, i. e. systems with very strong interactions (e. g. , hyd- gen bonding) between components or systems ...

"Inverse Coordination Chemistry: A Novel Chemical Concept" features and discusses the interesting array of inverse coordination complexes, from those with monoatomic or polyatomic centres to those with organic molecules as centres. While traditional coordination complexes consist of a metal atom at the centre surrounded by inorganic ligands, inverse coordination complexes show a reversed topology: a central non-metal atom surrounded by metallic ligands.Illustrative and concisely wr...

This thesis reports the discovery of metal nanoparticles having new structures that do not exist in bulk state and that exhibit hydrogen storage ability or CO oxidation activity. Research into the reaction of hydrogen with metals has attracted much attention because of potential applications as effective hydrogen storage materials, as permeable films, or as catalysts for hydrogenation. Also, CO oxidation catalysts have been extensively developed because of their importance to CO removal fr...

Scientific Essay from the year 2011 in the subject Chemistry - Anorganic Chemistry, grade: 3, University of Mosul (DBS), language: English, abstract: Some new metal(II) dichloride complexes with the ligands substituted nitrones of the general formula [ML2Cl2], where M= Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), L=OCH=CHCH=C-CH=N(O)C6H4X (X=H,p-CH3,CH3O,CH3CO,F,Cl,and Br) have been prepared and characterized by elemental analysis, IR,1H,13C NMR and Vis/Uv spectroscopy. The IR spectral data ...

As the search for renewable sources of energy grows more urgent, more and more attention is focusing on the blueprint offered by biological photosynthesis for translating the energy of our Sun into energy rich molecules like H2 and carbohydrates, commonly known as "solar fuels." These solar fuels have enormous potential to store high densities of energy in the form of chemical bonds as well as being transportable. This book offers a complete overview of the promising approaches to solar fu...
