Book excerpt: CETTE THESE EST UNE CONTRIBUTION A L'ETUDE DES CINETIQUES D'OXYDATION ET DE NITRURATION DES ALLIAGES BINAIRES MN-CU, AINSI QU'A LA CARACTERISATION DES COUCHES D'OXYDES OU NITRURES FORMES. LORS DE L'OXYDATION, LE GAIN DE MASSE SATISFAIT A UNE CINETIQUE CLASSIQUE DE TYPE PARABOLIQUE, CONDUISANT A DES ENERGIES D'ACTIVATION APPARENTES ENTRE 120 ET 140 KJ/MOL, POUR LES ALLIAGES A 5, 10 ET 36 AT.%MN. PAR CONTRE, LE COMPORTEMENT DES ALLIAGES DE COMPOSITION VOISINE DE 20 AT.% MN EST PLUS COMPLEXE: LA CINETIQUE D'OXYDATION ET LA NATURE DES COUCHES D'OXYDES EVOLUENT AVEC LA DUREE ET LA TEMPERATURE. L'IDENTIFICATION DES COUCHES S'EFFECTUE PAR RECOUPEMENT DES RESULTATS OBTENUS PAR ANALYSES EN DIFFRACTION DES RAYONS X, A LA MICROSONDE ET EN S.D.L. AUX FAIBLES TENEURS EN MN (5 ET 10 AT.%), AINSI QUE POUR LES TEMPERATURES INFERIEURES A 800C (20 AT.%), LES COUCHES D'OXYDES SE DIVISENT EN COUCHES EXTERNES PEU ADHERENTES (CUO/CU#2O) ET EN UNE COUCHE INTERNE ADHERENTE (MN#3O#4/MNO DISPERSEES DANS UNE MATRICE EN CUIVRE); POUR LES TEMPERATURES SUPERIEURES A 820C (20 AT.%) ET LES ALLIAGES A 36 AT.% MN, LA COUCHE EXTERNE EST CONSTITUEE DE L'OXYDE MIXTE CU#XMN#3##XO#4 ET LA COUCHE INTERNE EVOLUE VERS DEUX COUCHES (MN#3O#4 ET MNO). LE GAIN DE MASSE LIE A LA NITRURATION DES ALLIAGES MN-CU EST DIX FOIS PLUS PETIT QUE CELUI RELATIF A L'OXYDATION, TYPE CINETIQUE N'A PAS ENCORE ETE PRECISE. NEANMOINS LES ANALYSES NOUS PERMETTENT DE CONCLURE A LA FORMATION D'UNE SEULE COUCHE DE NITRURE MIXTE CU#1#-#XMN#3#+#XN, DE STRUCTURE TYPE PEROVSKITE

Available in PDF, EPUB and Kindle. Book excerpt: Cette these est une contribution a l'etude des cinetiques d'oxydation et de nitruration des alliages binaires mn-cu, ainsi qu'a la caracterisation des couches d'oxydes ou nitrures formes. Lors de l'oxydation, le gain de masse satisfait a une cinetique classique de type parabolique, conduisant a des energies d'activation apparentes entre 120 et 140 kj/mol, pour les alliages a 5, 10 et 36 at.%mn. Par contre, le comportement des alliages de composition voisine de 20 at.% mn est plus complexe: la cinetique d'oxydation et la nature des couches d'oxydes evoluent avec la duree et la temperature. L'identification des couches s'effectue par recoupement des resultats obtenus par analyses en diffraction des rayons x, a la microsonde et en s.d.l. Aux faibles teneurs en mn (5 et 10 at.%), ainsi que pour les temperatures inferieures a 800c (20 at.%), les couches d'oxydes se divisent en couches externes peu adherentes (cuo/cu#2o) et en une couche interne adherente (mn#3o#4/mno dispersees dans une matrice en cuivre); pour les temperatures superieures a 820c (20 at.%) et les alliages a 36 at.% mn, la couche externe est constituee de l'oxyde mixte cu#xmn#3##xo#4 et la couche interne evolue vers deux couches (mn#3o#4 et mno). Le gain de masse lie a la nitruration des alliages mn-cu est dix fois plus petit que celui relatif a l'oxydation, type cinetique n'a pas encore ete precise. Neanmoins les analyses nous permettent de conclure a la formation d'une seule couche de nitrure mixte cu#1#-#xmn#3#+#xn, de structure type perovskite

Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

This book was released on 2012-11-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Working Group M.O. (Interactions of soil minerals with organic components and microorganisms) (WGMO) of the International Soil Science Society (ISSS) was founded in 1990 at the 14th World Congress of Soil Science (Kyoto, Japan), with Professor P.M. Huang being the Chairman. Since then, the Working Group M.O. has served as a forum to bring together soil chemists, soil mineralogists, soil microbiologists, soil biochemists, soil physi cists and environmental, ecological, and health scientists. The objective of the Working Group M.O. is to promote research, teaching, and also the exchange of technology concerning the knowledge and the impact of the interactions between minerals-organics and microorganisms on environmental quality, agricultural sustainability, and ecosystem "health". This group is first a scientific group as defined just previously, but it also intends to develop exchange and transfer between scientists and engineers. The first International Meeting organized by Professor P. M. Huang, was held in Edmonton, Canada, in August 1992, where 87 papers were presented by scientists from 20 countries. Following this meeting, a two volume book was edited by P. M. Huang, J. Berthelin, J.-M. Bollag, W. B. McGill, and A. L. Page, entitled "Environmental impact of soil component interaction" : Volume I "Natural and anthropogenic organic-volume II "Metals, other inorganic and microbial activities", and published by c.R.C. Lewis Pub lishers (1995).

Available in PDF, EPUB and Kindle. Book excerpt: Provides a concise yet comprehensive introduction to XPS and AES techniques in surface analysis This accessible second edition of the bestselling book, An Introduction to Surface Analysis by XPS and AES, 2nd Edition explores the basic principles and applications of X-ray Photoelectron Spectroscopy (XPS) and Auger Electron Spectroscopy (AES) techniques. It starts with an examination of the basic concepts of electron spectroscopy and electron spectrometer design, followed by a qualitative and quantitative interpretation of the electron spectrum. Chapters examine recent innovations in instrument design and key applications in metallurgy, biomaterials, and electronics. Practical and concise, it includes compositional depth profiling; multi-technique analysis; and everything about samples—including their handling, preparation, stability, and more. Topics discussed in more depth include peak fitting, energy loss background analysis, multi-technique analysis, and multi-technique profiling. The book finishes with chapters on applications of electron spectroscopy in materials science and the comparison of XPS and AES with other analytical techniques. Extensively revised and updated with new material on NAPXPS, twin anode monochromators, gas cluster ion sources, valence band spectra, hydrogen detection, and quantification Explores key spectroscopic techniques in surface analysis Provides descriptions of latest instruments and techniques Includes a detailed glossary of key surface analysis terms Features an extensive bibliography of key references and additional reading Uses a non-theoretical style to appeal to industrial surface analysis sectors An Introduction to Surface Analysis by XPS and AES, 2nd Edition is an excellent introductory text for undergraduates, first-year postgraduates, and industrial users of XPS and AES.
