Zeolite synthesis is an active field of research. As long as this continues, new phases will be discovered and new techniques for preparing existing phases will appear. This edition of "Verified Synthesis of Zeolitic Materials" contains all the recipes from the first edition plus 24 new recipes. Five new introductory articles have been included plus those from the first edition, some of which have been substantially revised. The XRD patterns have been recorded using different instrument settings from those in the first edition and are intended to conform to typical X-ray diffraction practice. In most cases, only the XRD pattern for the productas synthesised is printed here. The exceptions are those phases which show marked changes in the XRD pattern upon calcination.

This issue of Aardkundige Mededelingen deals with industrial minerals, their resources, characteristics and applications. It is the result of an academic session on industrial minerals in honour of Em. Prof. Dr. R. Ottenburgs. The contributions are organized according to five topics. In a first part, 'The Industrial Mineral World', some considerations on our natural resources, their use and political impact are presented. In a second part of the study, 'Aggregates and Natural Building Stone', a number of case-studies on the use of industrial minerals as aggregate and ornamental or building stone are discussed. In a third part of the volume, 'Mortar, Cement and Concrete', the study of ancient mortars as well as exploratory research into new materials is illustrated. In a fourth session, 'Clays and Soils', environmental aspects of soils and the economical use of clay deposits are highlighted. In a fifth and final part of the book, 'Steel', the link between ores and industrial minerals is made. It is clear that the study of industrial minerals has many faces and covers many disciplines. The impact of industrial minerals on the world's economy, but also on the environment, cannot be emphasized enough. This book gives an overview of the wide and rich diversity of research currently performed in the realm of the industrial minerals.

The scientific community has argued for decades over the origin of giant craters on the earth. In a highly readable fashion, Kathleen Mark recounts the fascinating detective story of how scientists came to recognize metorite craters, both ancient and relatively recent.

Evaluates the risks to human health and the environment posed by the mining, refining, industrial use, and recycling of platinum and selected platinum compounds. Because of its exceptional catalytic properties, resistance to chemical corrosion, and high mechanical strength, platinum is widely used in the chemical and petroleum industries, most notably in the production of catalysts, including devices for reducing hazardous gas emissions. The growing use of catalytic converters to reduce pollution from automobile exhausts has caused a sharp increase in the world demand for this metal. Compounds such as cisplatin also have important therapeutic applications.

First published in 1957, this classic study has been reissued in a paperback version that includes an additional chapter bringing the material up to date. The author formulates the physical properties of crystals systematically in tensor notation, presenting tensor properties in terms of their common mathematical basis and the thermodynamic relations between them. The mathematical groundwork is laid in a discussion of tensors of the first and second ranks. Tensors of higher ranks and matrix methods are then introduced as natural developments of the theory. A similar pattern is followed in discussing thermodynamic and optical aspects.

Mehr als 10 Jahre nach Erscheinen der Erstauflage haben sich Herausgeber, Autoren und Verlag entschlossen, eine vollig liberarbeitete Fassung dieses Handbuches zu erstel- len. Das vielf: iltige und positive Echo aus den Reihen der Fachkollegen, der Industrie und der Ministerien war Ermutigung und Ansporn, wiederum ein aktuelles, inform a- tionsreiches Nachschlagewerk zu schaffen. Seit Anfang der siebziger Jahre haben sich tiefgreifende Wandlungen in der Rohstoff- wirtschaft vollzogen, deren Ausma und Wirkungen erst eine Dekade spater in vollem Ausma erkennbar wurden. Die pessimistischen bis apokalyptischen Prognosen des Club of Rome und die substantiellen EnergiepreiserhOhungen haben zwei gegenlaufige Tendenzen auf den Rohstoffmarkten bewirkt: einerseits eine euphorische Beurteilung der Preisentwicklung durch die Produzenten, die aufwendige Explorationsprogramme finanzierten und gro zligige Bergbauinvestitionen vornahmen sowie andererseits die Verstiirkung eines Rohstoftbewu tseins in den Industrielandern, wo der rationelle Ein- satz von Material, die konsequente Rlickgewinnung von Metallen und die Suche nach neuen Werkstoffen, wie Plastik und Keramik, zu einer Verringerung des Bedarfs fUhr- ten. Das Ergebnis ist Mitte der achtziger Jahre sehr deutlich zu erkennen. Stagnieren- der Verbrauch oder nur geringer Bedarfszuwachs auf der Nachfrageseite von Metall- mlirkten und ein Produktionsliberschu sowie zahlreiche standby-Bergbauprojekte auf der Angebotsseite Ftir die vorhersehbare Zukunft ist also eine physische Verknappung der metallischen Rohstoffe nicht zu erwarten. Auf hohem Verbrauchsniveau hat sich der Metallbedarf in den Industrielandern stabilisiert. Doch die Zeit der ausreichenden und preiswerten Versorgung wird urn so ktirzer sein, je weniger Wert auf langfristige Vorsorge gelegt wird.

Das Buch ist urspruenglich als Lehrbuch fuer Studenten kon- zipiert. Die dritte Auflage wurde betraechtlich erweitert und geht in einigen Punkten ueber die Ausbildungserforder- nisse hinaus. Es ist damit auch fuer den in der Glasfor- schung und -produktion taetigen Fachmann von Nutzen. Die Glaschemie als relativ junge Wissenschaft umfa t ein Grenzgebiet zwischen Chemie, Physik und Mineralogie und - fuer einige Anwendungen auch - der Biologie und Medizin. In diesem Buch nehmen die Chemie und auch die Physik die zen- trale Stellung ein. Das Hauptanliegen ist, dem Leser die Zu- sammenhaenge von chemischer Zusammensetzung, Struktur und Eigenschaften der unterschiedlichsten Glaeser aufzuzeigen und verstaendlich zu machen. Diese Kenntnisse sind die Basis einer zielgerichteten Glasentwicklung und Glasproduktions- steuerung. Dabei geht der Autor auch auf die Kernresonanzspektroskopie und die Elektronenmikroskopie als moderne Methoden der Glas- strukturforschung ein. Weil diese Methoden auch in der Pra- xis ihre Bedeutung bewiesen haben, wirdeinem Beduerfnis der zeitgemae en, praxisnahen Ausbildung Rechnung getragen.

Wasser". Dieser MeBfiihler wird nun irgendwo in der Natur installiert, der Beob- achter befindet sich weit entfemt, vor einem Bildschirm sitzend, auf den die MeB- signale iibertragen werden. Es solI festgestellt werden, ob es regnet oder nicht. 1st nun das MeBintervall zu groB eingesteIlt, etwa alle 12 Stunden ein Signal, so kann der Beobachter bei der Information, Nicht-Wasser" keine Aussage dariiber treffen, ob es regnet oder nicht. Da Regen fUr einen konkreten Raurn betrachtet ein Wechsel von "Wasser" und, Nicht-Wasser", eben die diskreten Regentropfen, darsteIlt, ist die Information, Nicht-Wasser" ebenso fiir Regen wie fUr schOnes Wetter richtig, bei Regen eben nur weniger oft. Nach dieser Erfahrung wird das MeBintervaIl nun verkleinert, alle paar Sekun- den erhiUt nun der Beobachter eine Information iiber "Wasser" und, Nicht- Wasser". Und jeden Abend urn halb Sieben bis Sieben Uhr regnet es, zurnindest meldet der Fiihler abwechselnd "Wasser" und, Nicht-Wasser". Des Ratsels Lo- sung: Jeden Abend wird der Garten gesprengt, in dem sich der MeBfiihler befindet. Der Raurn, der vom MeBfiihler erfaBt wird, ist zu klein, urn eindeutig zwischen natiirlichem Regen und anderen sporadischen Wassertropfenereignissen unter- scheiden zu konnen. Fiir einen an den Bildschirm verbannten Beobachter ist die Feststellung, ob es regnet, nur gegeben, wenn mehrere MeBfiihler iiber einen hin- reichend groBen Raum verteilt in entsprechend kurzen Intervallen eine Information dariiber liefem, ob sie gerade vom Wasser oder von Luft umgeben sind. MeBraurn und MeBzeit bestimmen also die durch die Messungen gewonnene Aussage.

With a new introductory chapter outlining the "bigger picture," this fully updated resource will guide students to an even greater mastery of petrology.

Bentonite are usually found in deep geographical areas. They are produced from rock, fossils, weathering of volcanic ash and disposal of high-level of radioactive waste in many countries. Bentonite mainly consist of clay mineral such as montmorillinite and kaolinite. They mainly exist in cationic form of organic compounds such as aromatic or aliphatic hydrocarbon and are employed to modify high cations exchange capacity, higher structural integrity, thermal conductivity, high chemical buffering capacity, and stiffness. Bentonite is a layer of natural silicate clay mineral having numerous properties such as large specific surface area, great absorption and interlayer exchangeable cation. Bentonite consists of outstanding physico-chemical properties which make it applicable in the areas such as water treatment, medical, groundwater barrier, farming, and construction. They are well known to be one of the most versatile and inexpensive treatments. The current book describes the bentonite characteristic, uses and implications for the environment in many areas of environmental science in particular, such as remediation, clean energy, water research and waste management. Researchers working in the area will benefit from the fundamental concepts and advanced approaches described in the book. The book is going to also be beneficial to researchers who are working for their graduate and postgraduate degrees in the area of science and technology. The book also provides a platform for all researchers as it covers a wide background in the subject from recent literature, abbreviations, and summaries. Additionally, this book covers a broader research area of chemistry, physics, environmental science, materials science, polymer science and engineering to present an interdisciplinary approach. This book contains the fundamental knowledge as well as recent advancements in the research and development of bentonite. The book also covers recent approaches and prospects about the current research and development of bentonite.

Hydrothermal crystal growth offers a complementary alternative to many of the classical techniques of crystal growth used to synthesise new materials and grow bulk crystals for specific applications. This specialised technique is often capable of growing crystals at temperatures well below their melting points and thus potentially offers routes to new phases or the growth of bulk crystals with less thermal strain. Borate crystals are widely used as nonlinear optical, laser and luminescent materials due to their diversified structures, and good chemical and physical properties. The growth of high-quality borate crystals is required for their applications. A fundamental problem for borate crystal growth is the high-temperature melt structures in the crystal growth systems. This book discusses several crystals and the crystal growth processes.

Since the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Act) was passed in 2010, relevant U.S. agencies have undertaken various activities related to responsible sourcing of conflict minerals from the Democratic Republic of the Congo (DRC) and adjoining countries. In response to the Act, the Department of State (State) and the U.S. Agency for International Development (USAID) developed a strategy in 2011 to address the linkages among human rights abuses, armed groups, and the mining of conflict minerals and are implementing various strategy objectives. This book examines, among other things, the extent to which relevant U.S. agencies have undertaken activities related to responsible sourcing of conflict minerals; and what is known about the status of, and information provided by, stakeholder initiatives focused on responsible sourcing of conflict minerals from the DRC and adjoining countries.

Die Beugung von Rontgenstrahlen wird heute in vielen Labors zur schnellen, sicheren und zerstorungsfreien Identifikation von Festkorperproben benutzt. Der Einsatz von Kleinrechnern (PCs) und von schnelleren Detektoren hat in der Rontgenpulverdiffraktometrie zu einer Renaissance sowohl in der Phasenanalyse von Gemischen als auch in der Strukturverfeinerung aus Pulverdaten gefuhrt. Das Buch ist aus mehreren Vorlesungen und Ubungen des Autors entstanden und dient als praxisbezogenes Lehrbuch mit zahlreichen Abbildungen Studenten der Kristallographie, Mineralogie, Geologie, Chemie und der Materialwissenschaften. Es wird ausserdem als Nachschlagewerk von jedem mit dieser Methode arbeitenden Wissenschaftler verwendet. Dies ist die zweite Auflage des Buches. Gegenuber der ersten Auflage wird die Rietveld-Methode und die neue Methode der Profilanpassung durch die Verwendung von physikalisch sinnvollen Fundamentalparametern ausfuhrlicher behandelt."

Nanocrystalline apatites constitute the main inorganic part of human hard tissues (bone and teeth), and a growing focus is devoted to prepare synthetic analogs, so-called "biomimetic", able to precisely mimic the morphological and physical-chemical features of biological apatites. In fact, it is reasonable to hypothesize that by virtue of their high similarity with the biogenic calcium phosphates, synthetic nano-sized and ionic substituted apatite nanocrystals can display better biological performances than coarser and ceramic hydroxyapatite. For this reason, the study of their crystallization mechanisms and the possibility to tailor the structural and physical-chemical properties of these materials open several possibilities to prepare optimal devices in medical sciences and also to better investigate the biomineralization processes of living organisms. This book is divided in three main parts and is principally devoted to highlight the recent progresses on the preparation and characterization of multifunctional nanocrystalline apatites with tailored properties to be used as healthcare materials (i.e. nanoparticles for drug or gene delivery and materials for bone substitution and regeneration). The first part is intended to be a comprehensive review of the importance and the occurrence of calcium phosphates in nature (geological and biological occurrence) and to underline the peculiar characteristics of nanocrystalline apatites. The aim of the second part is to show the most important analytical techniques for the characterization of apatite features and to describe the new theories behind the apatite crystallization and dissolution processes. The last part describes the traditional and the most exciting and innovative applications of pure, ionic-substituted, and organic-functionalized apatite as biomaterial. The chapters, written by eminent scientists, will serve as an important and useful reference source for a broad audience that consists of both expert (materials scientists, biomedical engineers and biologists) and non-expert readers to who want to improve their knowledge in the field of apatite based biomaterials.
