[en] An effective technique for making nonmagnetic WC based cemented carbide by using Ni(W) solid solution manufactured from ammonium paratungstate(APT) as the binder was developed. It was found that powder particles using APT as the W source had larger contact area between W and Ni and higher activity, which was conducive to the mutual diffusion between Ni and W, leading to a faster solid phase reaction and higher content of W diffused into Ni. And the mechanical and nonmagnetic properties of WC based cemented carbide derived from nonmagnetic Ni(W) solid solution as the binder are much better than those derived from pure Ni as the binder.

[en] It is well-known that a strand burner is an apparatus that provides burning rate measurements of a solid propellant at an elevated pressure in order to obtain the burning characteristics of a propellant. This paper describes the facilities developed by author that was used in his studies. The burning rate characteristics of solid propellant have be evaluated over five different chamber pressures ranging from 1 atm to 31 atm using a strand burner. The strand burner has a mounting stand that allows the propellant strand to be mounted vertically. The strand was ignited electrically using hot wire, and the burning time was recorded by electronic timer. Wire technique was used to measure the burning rate. Preliminary results from these techniques are presented. This study shows that the strand burner can be used on propellant strands to obtain accurate low pressure burning rate data

[en] Understanding the physics of solids has made enormous progress in the last century, revolutionizing our daily lives in many ways. This development continues, and there is little doubt that modern solid state physics is necessary to address some of the challenges we face today. In its 6th revised edition, the work covers a wide range of physical phenomena that occur in solids and discusses fundamental concepts for their description. The material is selected so that all relevant current sub-areas are included and together provide a comprehensive overview. A special feature of this textbook is that the physics of disordered solids, which is usually only presented very briefly or not at all, is consistently incorporated into the treatment of the material and complements the physics of ideal crystals. Disordered solids are omnipresent in our daily lives and play an important role in numerous technical applications. The textbook is aimed at students who want to study solid state physics at an introductory and advanced lecture level. - Current and experiment-oriented presentation of solid state physics. - The revised, 6th edition deepens the chapter on magnetism.

Das Verständnis der Physik von Festkörpern hat im letzten Jahrhundert enorme Fortschritte gemacht und unser tägliches Leben in vielerlei Hinsicht revolutioniert. Diese Entwicklung geht weiter, und es besteht kaum ein Zweifel daran, dass die moderne Festkörperphysik notwendig ist, um einige der Herausforderungen zu bewältigen, denen wir uns heute gegenübersehen. In seiner 6., überarbeiteten Auflage deckt das Werk ein breites Spektrum physikalischer Phänomene ab, die in Festkörpern auftreten, und erörtert grundlegende Konzepte zu deren Beschreibung. Das Material ist so ausgewählt, dass alle relevanten aktuellen Teilgebiete einbezogen werden und zusammen einen umfassenden Überblick bieten. Eine Besonderheit dieses Lehrbuches ist, dass die Physik ungeordneter Festkörper, die üblicherweise meist nur sehr kurz oder gar nicht dargestellt wird, konsequent in die Behandlung des Stoffes einfließt und die Physik der idealen Kristalle ergänzt. Ungeordnete Festkörper sind in unserem täglichen Leben allgegenwärtig und spielen in zahlreichen technischen Anwendungen eine wichtige Rolle. Das Lehrbuch richtet sich an Studierende, die Festkörperphysik auf einführendem und fortgeschrittenem Vorlesungsniveau studieren wollen. - Aktuelle und am Experiment orientierte Darstellung der Festkörperphysik. - Die überarbeitete, 6. Auflage vertieft v.a. das Kapitel zum Magnetismus.Source

[en] An oxide system Sc2−xFexO3 prepared by a conventional solid-state reaction method was found to change its color from the well-known reddish color at x = 2.0 to a yellowish color at x ≈ 0.6 and to a greenish-yellow color at 0.2 ≤ x ≤ 0.4. According to the structural characterization results for this system, the monophasic corundum phase region persists for 1.6 ≤ x ≤ 2.0, whereas the bixbyite-type phase is monophasic for 0 ≤ x ≤ 1.0. The intermediate region of 1.2 ≤ x ≤ 1.4 is a mixed region. Because green is a rare color for iron oxides, powder of the most typical composition, x = 0.4, with (L*, a*, b*) coordinates of (77.3, −0.5, 51.0) was tested as a pigment for a Japanese-style painting and also as an overglaze enamel on porcelain; reasonably good results were obtained.

[en] The paper presents the results of mathematical and experimental studies of the process of gasification of municipal solid waste in a plasma electric furnace. The energy consumption for gasification of SMW with the organic and inorganic components of morphological composition was investigated during these studies. The effect of reducing the energy consumption during waste gasification, excluding the inorganic component of SMW was also investigated. The paper presents the results of computational and experimental studies of SMW gasification and reveals the effect of the inorganic part on the energy balance of an electric plasma furnace. (paper)
