Gleichgewichts- und Wachstumsformen von Kristallen by B. Honigmann

By B. Honigmann

Die Frage nach der au13eren shape, d. h. nach der Tracht und dem Habi tus eines Kristalles, steht im Mittelpunkt aller Erorterungen iiber die Bil dung und das Wachstum kristalliner Phasen. Dariiber hinaus werden durch diese Frage zahlreiche Probleme der Physik und Chemie der Festkorper und deren Grenzflachen beriihrt. Durch das Thema vorliegender Schrift ist bereits zum Ausdruck gebracht, da13 das Habitus-Tracht-Problem wachsender Kristalle auf der Grundlage der durch J. W. GIBBS (1878) definierten shape minimaler Oberflachen energie zu erortern ist. Schon CURIE (1885) und WULFF (1901) hatten ver sucht, diese shape als Schliissel zum Verstandnis von Wachstumsformen zu betrachten. Die Annahme, daB auch ein wachsender Kristall diese Begren zungsart anstrebt, ist jedoch nicht zutreffend. Die shape minimaler Ober flachenenergie entsteht nur im Gleichgewicht zwischen Kristall und um gebender section (z. B. Dampf, Losung, Schmelze); sie wird daher als Gleich gewichtsform bezeichnet. Es ist insbesondere das Verdienst von STRANSKI und KAISCHEW, den Zusammenhang von Gleichgewichts- und Wachstumsformen unter ideali sierten Voraussetzungen geklart zu haben. Diese "Oberlegungen bilden einen wesentlichen Bestandteil der durch KOSSEL, STRANSKI und VOLMER entwickelten allgemeinen Theorie des Kristallwachstums [vgl. STRANSKI (1949, 1950) und KNACKE und STRANSKI (1952)].

Adsorption and the Gibbs Surface Excess by D. Chattoraj

By D. Chattoraj

The subject material of this ebook isn't fullyyt new in that a lot has been written concerning the nation of the interfacial chemistry in different textbooks. even if, the authors have came across that there's quite a necessity for a ebook that may lead an investigator, a pupil, or a beginn er in the course of the in-depth figuring out and outlines fascinated with the derivations and utilization of the adsorption equations in accordance with the unified thought of the Gibbs floor extra. The derivation of the unique Gibbs equation for the liquid interface has been amplified with reformulations and criticisms. makes an attempt were usually made to narrate the outside extra amounts with the thermodynamic houses of the bodily outlined interfacial section. within the final 20 years, important purposes of the Gibbs equations were made for the learn of adsorption at solid-liquid as weIl as liquid-gas interfaces shaped within the presence of the multicomponent suggestions within the bulk. those contemporary remedies develop into priceless for the experimental reports of the adsorption of electrolytes and interfacial houses relating to impartial and charged monolayers. The consistency of the experimental effects with these to be anticipated from the theories of double layer wishes cautious exam. An test has been made to provide in one quantity some of these advancements in accordance with the unified suggestion of the Gibbs floor extra. The research of the adsorption from resolution is of substantial significance within the box of biology and in lots of different branches of utilized science.
