Book Synopsis Spillover and Mobility of Species on Solid Surfaces by : A. Guerrero-Ruiz
Download or read book Spillover and Mobility of Species on Solid Surfaces written by A. Guerrero-Ruiz and published by Elsevier. This book was released on 2001-08-02 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Spillover and Mobility of Species and Solid Surfaces" collects the papers which were presented at the Fifth International Conference Spillover, either as oral or poster contributions, as well as the summaries of the invited lectures. This congress and its publication in the Studies on Surface Science and Catalysis series follow the tradition of previous conferences on spillover, initiated in Lyon, 1983, and continued in Leipzig, 1989, Kyoto 1993 and Dalian, 1997. For the fifth conference, held in S.L. el Escorial (Madrid), the organising committee has attempted to compile representative contributions which illustrate the advances in understanding the spillover phenomenon since 1997. Spillover is a process taking place during the interface of gas reactant molecules (mainly hydrogen and oxygen) on solid surfaces. However, different contributions to the more general area of the chemistry at surfaces, related with the mobility and migration of species, diffusion through membranes, fuel cell catalysts, etc., have also been included. In fact the title of the present volume summarizes this attempt to extend the conference topics towards dynamics at surfaces.Among the 70 contributions received, the 56 accepted papers were selected on the basis of the reports of at least two international reviewers, according to standards comparable to those applied for other specialised journals. These papers are from 21 different countries.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Os óxidos mistos CeO2-ZrO2 são utilizados como suporte de catalisadoresautomotivos devido a sua capacidade de estocar e liberar oxigênio em condiçõespobres ou ricas de combustível, respectivamente, a fim de auxiliar nas reaçõesredox que minimizam a emissão de poluentes oriunda da queima incompleta docombustível. Neste trabalho, os óxidos mistos CeO2-ZrO2 foram preparados pelométodo de coprecipitação, utilizando-se como sais precursores o ZrO(NO3)2 e o(NH4)2Ce(NO3)6 ou Ce(NO3)3 com a finalidade de se observar a influência do salprecursor de cério no sistema CeO2-ZrO2. Além disso, investigou-se o efeito dealgumas condições de preparação como o envelhecimento do precipitado, ocontrole de pH durante a síntese, a secagem e o envelhecimento térmico nosóxidos mistos obtidos. Os resultados mostram que a variável mais significante napreparação dos óxidos mistos CeO2-ZrO2 por coprecipitação é o sal precursor decério. Em todas as amostras preparadas a partir do precursor de cério IV houve aformação de solução sólida, enquanto que no caso das amostras preparadas apartir do precursor de cério III observou-se a formação de duas fases segregadas, c-CeO2 e t-ZrO2. Além disso, concluiu-se que a redução do material obtido nãoocorre somente na superfície, mas também na parte mássica e que os materiaisformados por solução sólida são os que apresentam melhor capacidade dearmazenamento de oxigênio o que é muito importante para o uso em catalisadoresautomotivos. O envelhecimento térmico do catalisador mostrou que há umasinterização devido à alta temperatura e que também há uma segregação dasolução sólida quando esta foi submetida às condições de envelhecimentoutilizadas.
Book Synopsis Preparation and Characterization of Co(II)/ZrO2 Solid Solution by : Ping Wu
Download or read book Preparation and Characterization of Co(II)/ZrO2 Solid Solution written by Ping Wu and published by . This book was released on 1987 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Samples of cubic zirconium oxide containing up to almost 10 atomic percent cobalt were prepared by codecomposition of the nitrate. Magnetic susceptibility measurements confirmed the limit of solubility and the presence of the cobalt as Co(II). The reduction of the cobalt inserted in cubic zirconia took place at a considerably higher temperature than bulk cobalt oxide. Cubic Zro2 samples containing some transition metal oxides including rhodium oxide (1), iron oxide (2), chromium oxide (3) and nickel oxide (4) were studied previously in this laboratory. Their structures, magnetic properties and the stabilities towards reduction have been studied. Zro2 is characteristic of an absence of reaction between the ZrO2 support and the catalyst. It is the purpose of this work to investigate the formation of solid solution between ZrO2 and cobalt oxide and to study the magnetic properties of such a system. In addition, the stability towards reduction of cubic Zro2 samples containing various concentrations of reacted cobalt oxide will be determined.

Book Synopsis DEVELOPMENT OF A BATCH PROCESS FOR THE PRODUCTION OF A ZrO2-UO2 SOLID SOLUTION. by :
Download or read book DEVELOPMENT OF A BATCH PROCESS FOR THE PRODUCTION OF A ZrO2-UO2 SOLID SOLUTION. written by and published by . This book was released on 1957 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A batch process on the 2 kg scale was developed for the production of ZrO2--UO2 solid solution in the weight proportion of about 4 to 1. The product is tetragonal ZrO2-- UO2 solution, with no UO2 lines showing on the x-ray powder diffraction patterns. The solid solution is prepared from a precipitate of Zr(OH)4-- (NH4)2U /sub 2O-- which is filtered, dried, milled, screened to minus 325 mesh, and heated at 9OO deg C in H2 for 4 hours. The success of the preparation depends strongly on the conditions of the precipitation, with precipitation from dilute salt solution being necessary to avoid undissolved UO2 in the final product.

Download or read book Monument 14 written by Emmy Laybourne and published by Feiwel & Friends. This book was released on 2012-06-05 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Your mother hollers that you're going to miss the bus. She can see it coming down the street. You don't stop and hug her and tell her you love her. You don't thank her for being a good, kind, patient mother. Of course not—you launch yourself down the stairs and make a run for the corner. Only, if it's the last time you'll ever see your mother, you sort of start to wish you'd stopped and did those things. Maybe even missed the bus. But the bus was barreling down our street, so I ran. Fourteen kids. One superstore. A million things that go wrong. In Emmy Laybourne's action-packed debut novel, six high school kids (some popular, some not), two eighth graders (one a tech genius), and six little kids trapped together in a chain superstore build a refuge for themselves inside. While outside, a series of escalating disasters, beginning with a monster hailstorm and ending with a chemical weapons spill, seems to be tearing the world—as they know it—apart.

Book Synopsis Sol-Gel Materials by : John D. Wright
Download or read book Sol-Gel Materials written by John D. Wright and published by CRC Press. This book was released on 2018-10-03 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sol-Gel processing methods, first used historically for decorative and constructional materials, were extensively developed in the last century for applications such as glasses, ceramics, catalysts, coatings, composites and fibres. Today they are reaching their full potential, enabling the preparation of new generations of advanced materials not easily accessible by other methods yet using mild, low-energy conditions. The topic is therefore increasingly included in advanced undergraduate, MSc and PhD programmes in the areas of chemistry, physics and materials science. This concise introductory text, written at the advanced undergraduate/first-year postgraduate level, is also suitable as an introduction to the development, mechanisms, chemistry, characterisation methods and applications of the technique. It provides readers with an extensive yet concise grounding in the theory of each area of the subject and details the real and potential applications and the future prospects of sol-gel chemistry.
