    Description / Table of Contents: Substantially revising and updating the classic reference in the field, this handbook offers a valuable overview and myriad details on current chemical processes, products, and practices. No other source offers as much data on the chemistry, engineering, economics, and infrastructure of the industry. The Handbook serves a spectrum of individuals, from those who are directly involved in the chemical industry to others in related industries and activities. It provides not only the underlying science and technology for important industry sectors, but also broad coverage of critical supporting topics. Industrial processes and products can be much enhanced through observing the tenets and applying the methodologies found in chapters on Green Engineering and Chemistry (specifically, biomass conversion), Practical Catalysis, and Environmental Measurements; as well as expanded treatment of Safety, chemistry plant security, and Emergency Preparedness. Understanding these factors allows them to be part of the total process and helps achieve optimum results in, for example, process development, review, and modification. Important topics in the energy field, namely nuclear, coal, natural gas, and petroleum, are covered in individual chapters. Other new chapters include energy conversion, energy storage, emerging nanoscience and technology. Updated sections include more material on biomass conversion, as well as three chapters covering biotechnology topics, namely, Industrial Biotechnology, Industrial Enzymes, and Industrial Production of Therapeutic Proteins.

    Description: The Pterophoridae (Ochyroticinae, Deuterocopinae, Pterophorinae (Tribus: Platyptiliini, Exelastini, Oxyptilini)) species of the Neotropical fauna are reviewed. The species are redescribed. Moths are illustrated in colour for the first time, their genitalia are illustrated in line drawings. The examination of type specimens revealed the presence of four new synonyms: Platyptilia juanvinas Gielis, 1999, is a junior synonym of Platyptilia gravior Meyrick, 1932; Platyptilia jonesi Gielis, 1996, is a junior synonym of Platyptilia semnopis Meyrick, 1931; Oxyptilus maleficus Meyrick, 1926, is a junior synonym of Leptodeuterocopus neales (Walsingham, 1915); Lioptilus parvus Walsingham, 1880, is a junior synonym of Lioptilodes albistriolatus (Zeller, 1871). During the study of much new material 40 new species were discovered: Leptodeuterocopus tungurahue, L. angulatus, L. panamaensis, L. duchicela, Sochchora mulinus, Melanoptilia nigra, Platyptilia spicula, Stenoptilodes maculatus, S. agricultura, S. heppneri, S. medius, S. altiaustralis, Postplatyptilia nebuloarbustum, P. antillae, P. caribica, P. uruguayensis, P. pluvia, P. seitetazas, P. transversus, P. carchi, P. boletus, P, ugartei, P. drechseli, P. corticis, P. zongoensis, P. vorbecki, Amblyptilia landryi, A. kosteri, Lioptilodes altivolans, L. arequipa, L. yungas, L. salarius, L. cocodrilo, Michaelophorus margaritae, M. bahiaensis, Geina integumentum, Capperia browni, Buckleria brasilia, Megalorhipida paraiso, M. dubiosa. In the larger genera the species are arranged in groups. For a distinct group of species a new genus: Melanoptilia is proposed. A comprehensive checklist of the species has been made. To facilitate identification a key is presented to the genus level.

    Description: Dasypoda intermedia spec. nov. from Iran is described. Its description fills a gap of our knowledge of the East Mediterranean fauna of the genus Dasypoda. The West Mediterranean Dasypoda species are well known but the eastern species lack convincing records. Moreover, D. intermedia spec. nov. is a very interesting species from a phylogenetic point of view. It shares some characters common to subgenera Dasypoda s. str. and Megadasypoda Michez, 2004, which provide further evidence for the close relationship of both subgenera.

    Description: Thirty-one species of the family Platystictidae of the Philippines are revised, i.e. all species recognised, excluding the species of the Drepanosticta halterata-group. The following new taxa are described: 16 species in Drepanosticta Laidlaw: D. acuta spec. nov., D. aurita spec. nov., D. centrosaurus spec. nov., D. clados spec. nov., D. flavomaculata spec. nov., D. furcata spec. nov., D. hermes spec. nov., D. krios spec. nov., D. luzonica spec. nov., D. malleus spec. nov., D. myzouris spec. nov., D. paruatia spec. nov., D. pistor spec. nov., D. quadricornu spec. nov., D. rhamphis spec. nov., D. trachelocele spec. nov., two in Protosticta Selys, viz. P. lepteca spec. nov. and P. plicata spec. nov., and three in Sulcosticta gen. nov., viz. S. striata spec. nov., S. pallida spec. nov. and S. viticula spec. nov. The status of eleven previously described nominal taxa is established. One, D. septima Needham & Gyger, is doubtfully considered a synonym of D. mylitta Cowley. Based on a preliminary phylogenetic analysis, the species of Drepanosticta are divided into informal species groups. Most species of the Philippines have affinities to species of Sulawesi, the Moluccas and New Guinea. Several species confined to Palawan have sister-group relationships with species from Borneo. The affinities of various other species confined to the Sulu archipelago, are unsettled as yet. The species of Platystictidae here assigned to Protosticta Selys are presumably not closely related to the type species, P. simplicinervis Selys from Sulawesi. However, a better placement has to await a more detailed phylogenetic study of the family. For three species the new genus Sulcosticta gen. nov. is erected. These species are closely allied based on the structure of the appendages, but should have been assigned to different genera if based on the present generic definitions. Many species here described have small distributional ranges, a common phenomenon in Platystictidae. Since most forests in the Philippines are heavily under threat or have already disappeared in the last fifty years, several taxa described in this paper should be considered under threat of immediate extinction.

    Notes: Von der Vorstellung ausgehend, daß das Wasser der hauptsächlichste Mineralisator bei Eruptivgesteinsbildungen sei und das Magma eine wenn auch stark konzentrierte wässerige Lösung, wurden die für die gewöhnlichen wässerigen Lösungen geltenden Prinzipien auf die magmatische Lösung übertragen. Da wir in einer Lösung jeden beliebigen Lösungsgenossen als Lösungsmittel auffassen können, wurden die Mineralisatoren derart betrachtet, daß wir jeden derselben der Reihe nach als Lösungsmittel aufzufassen suchten.

    Notes: Die über das Vorkommen des primären und sekundären Polyhalits ausgeführten Untersuchungen stimmen mit den Angaben VAN'T HOFFS in vielem überein. Mit Ausnahme der carnallithaltigen Lagerteile kann der Polyhalit, in größeren oder geringeren Mengen, fast in allen kalihaltigen Teilen des älteren Zechsteinsalzlagers angetroffen werden. Als primär abgelagertes Salz tritt er hauptsächlich im stellenweise entwickelten polyhalitischen Steinsalz (Polyhalit-Halit) auf. In der kieseritischen Übergangszone (Hangend-Polyhalit) des Staßfurter Carnallitlagers treffen wir in der Gestalt des Anhydrits, Kieserits, Sylvins und Carnallits bereits nur sekundäre Umwandlungsprodukte dieses primären Polyhalits vor. Es haben eingesickerte Laugen des fortschreitenden Eintrocknungsvorganges, als auch die in der Tiefe erfolgte Einwirkung chlormagnesiagesättigter Laugen des Carnallitgebietes zu diesen Umwandlungsvorgängen beigetragen.

    Notes: A. Es wurden folgende Methoden zur Darstellung des Gadoliniums geprüft: 1Die Alkalidoppelsulfatmethode.Die Methode erweist sich zur Darstellung des Gadoliniums nur bedingt als brauchbar. Ihre unbequeme Handhabung verbietet eine erschöpfende Anwendung zur Darstellung einer Einzelerde. Dagegen vermag sie gut Dienste zu leisten, wenn es sich darum handelt, ein umfangreiches schwachgadoliniumhaltiges Material in zwei Teile zu teilen, in deren einem man das Gadolinium konzentrieren kann.2Die Hydrazindoppelsulfatmethode.Diese Methode wurde neu ausgearbeitet; sie wirkt der Alkalidoppelsulfatemethode analog und in dem gleichen Sinne. Sie hat gegenüber jener den Vorzug, daß man die Menge der abzuscheidenden Erden in der Hand hat.Es werden die Hydrazindoppelsulfate einiger typischer Erden dargestellt und ihre Zusammensetzung durch Analyse ermittelt.3Die fraktionierte Kristallisation der Bromate.Diese von C. James zuerst angegebene Methode eignet sich in hervorragender Weise zur Trennung der Terbinerden von den Yttererden. Die Scheidung verläuft schnell und gestattet das Arbeiten in größtem Maßstabe, infolge der großen Löslichkeit und guten Kristallisationsfähigkeit der Bromate. Man kann jedoch mit ihr keine Trennung der Ceriterden von den Terbinerden erzielen, da die Löslichkeit des Gadoliniumbromats zwischen den Löslichkeiten von Samarium und Neodymbromat liegt. Die Methode muß also mit einer anderen, zur Abscheidung der Ceriterden dienenden verbunden werden.

    Notes: Die Versuche über den Basenaustausch im Permitit wurden fortgesetzt; beim Austausch des Kupfers gegen die Erdalkalien wurde die Unabhängigkeit von der Verdünnung für gleichwertige Ionen neuerdings bestätigt gefunden und gleichzeitig eine analoge Gesetzmäßigkeit im Verhalten der Homologen beim Austausch wie bei den Alkalien festgestellt. An der Reihe Silber-Barium wurde eine Formel für den Austausch zwischen ein- und zweiwertigen ionen erprobt und auch für die Reihe Natrium-Calcium gültig befunden; in dieser Reihe wurde außerdem eine Mischungslücke konstatiert und gezeigt, daß die Umwandlung der beiden festen Phasen  -  mindestens von einer Seite  -  beträchtliche Zeit braucht. Schließlich wurde noch am Austausch Silber-Lanthan gezeigt, daß auch dreiwertige Ionen zum Austausch befähigt sind und daß der Einfluß der Verdünnung hier besonders grß ist.

    Notes: 1. In der vorstehenden Arbeit wird die Frage aufgeworfen, wie genau die Grenzwerte des molaren Leitvermögens μ∞ bei den organischen Ionen bekannt sind. Dieselben wurden bisher aus den bei verschiedenen Verdünnungen (32, 64, 128, 256, 512, 1024) gemessenen Werten des molaren Leitvermögens μ nach der sogen. OSTWALD-BREDIGschen Regel dadurch extrapoliert, daß man nach einer von diesen Forschern gegebenen, auf empirischem Wege gefundenen Tabelle zu jedem Werte von μ ein Zahl addiert and nach der Gleichung \documentclass{article}\pagestyle{empty}\begin{document}$$ \mu _\infty ^ - = \mu + \Delta $$\end{document} den Wert von μ∞ findet.
