This book was released on 1959 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans ce travail, nous avons effectué une étude comparée des transformations allotropiques alpha ⇋ gamma du fer et alpha ⇋ bêta de l'uranium qui s'effectuent toutes deux suivant le même processus de germination et de croissance. [...] Afin de mettre en évidence d'une façon plus claire les analogies et les différences qui se présentent entre le fer et l'uranium, chacun des aspects des phénomènes sera exposé dans un seul paragraphe pour ces deux métaux. Ce travail sera divisé en trois parties : 1) appareillage et méthodes ; 2) régénération de cristaux uniques de fer alpha et d'uranium alpha, par conservation de germes, au cours des transformations allotropiques alpha ⇋ gamma du fer et alpha ⇋ bêta de l'uranium ; 3) macles de transformation de fer alpha et de fer gamma.

Download or read book Karst Hydrogeology and Geomorphology written by Derek Ford and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007

Download or read book Surface and Interface Chemistry of Clay Minerals written by Robert Schoonheydt and published by Elsevier. This book was released on 2018-11-05 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface and Interface Chemistry of Clay Minerals, Volume 9, delivers a fundamental understanding of the surface and interface chemistry of clay minerals, thus serving as a valuable resource for researchers active in the fields of materials chemistry and sustainable chemistry. Clay minerals, with surfaces ranging from hydrophilic, to hydrophobic, are widely studied and used as adsorbents. Adsorption can occur at the edges and surfaces of clay mineral layers and particles, and in the interlayer region. This diversity in properties and the possibility to tune the surface properties of clay minerals to match the properties of adsorbed molecules is the basis for study. This book requires a fundamental understanding of the surface and interface chemistry of clay minerals, and of the interaction between adsorbate and adsorbent. It is an essential resource for clay scientists, geologists, chemists, physicists, material scientists, researchers, and students. - Presents scientists and engineers with a resource they can rely on for their own research and work involving clay minerals - Includes an in-depth look at ion exchange, adsorption of inorganic and organic molecules, including polymers and proteins, and catalysis occurring at the surfaces of clay minerals - Includes materials chemistry of clay minerals with chiral clay minerals, optical materials and functional films
