“…The final chapter examines several more challenging systems, such as fluids near the critical point, liquid metals, molten salts, colloids, and aqueous protein solutions.This book offers a thorough account of the available equilibrium theories for the thermodynamic and structural properties of fluids and solids, with special focus on perturbation theories, emphasizing their applications, strengths, and weaknesses. …”

“…In oligotrophic environments, dust and nutrient inputs via atmospheric routes are considered important sources of macro-nutrients and micro-trace metals fuelling primary and secondary production. …”

“…Molecular magnets show many properties not met in conventional metallic magnetic materials, i.e. low density, transparency to electromagnetic radiation, sensitivity to external stimuli such as light, pressure, temperature, chemical modification or magnetic/electric fields, and others. …”

“…Welche Bedeutung hat die Digitalisierung für die Aus- und Fortbildung in den elektro-, informations-, metall- und fahrzeugtechnischen Berufen? Der Einsatz digitaler Technik führt hier zu starken Veränderungen der Tätigkeiten und Arbeitsabläufe. …”

“…The world of materials hosts an extraordinarily diverse wealth of architectures (crystals, glass, foams and gels for examples) and types of physical behaviour (metals, insulating materials, semi-conductors or superconductors). …”

“…While the main focus is on the increasing presence of “re-exports” in reported exports of goods data, this paper also addresses some other statistical and data issues that need to be considered, such as treatment of confidential (or “unallocated”) trade in goods; trade in secondhand goods, scrap metal and other waste; differences in trade statistics across international statistical agencies; and the additional problems encountered when converting product-based trade data to industry-based classifications. …”

“…The volume contains 20 Chapters covering altogether many (although not all) semiconductors of technological interest, starting with the IV-IV group compounds (SiC and SiGe), carrying on with the binary and ternary compounds of the III-V (GaAs, AlGaAs, GaSb, InAs, GaP, InP, and GaN) and II-VI (HgTe, HgCdTe) families, the metal oxides (CuO, ZnO, ZnCoO, tungsten oxide, and PbTiO3), and finishing with Bi (a semimetal)…”

“…The book then: Explains the effects of radiation on digital commercial devices, including microprocessors and volatile and nonvolatile memories—static random-access memories (SRAMs), dynamic random-access memories (DRAMs), and Flash memories Examines issues like soft errors, total dose, and displacement damage, together with hardening-by-design solutions for digital circuits, field-programmable gate arrays (FPGAs), and mixed-analog circuits Explores the effects of radiation on fiber optics and imager devices such as complementary metal-oxide-semiconductor (CMOS) sensors and charge-coupled devices (CCDs) Featuring real-world examples, case studies, extensive references, and contributions from leading experts in industry and academia, Ionizing Radiation Effects in Electronics: From Memories to Imagers is suitable both for newcomers who want to become familiar with radiation effects and for radiation experts who are looking for more advanced material or to make effective use of beam time…”

“…Dabei ist die Anwendung unendlich vielfältig – es lassen sich alle Arten von Materialien wie Glas, Metall, Holz, Pappe oder Kunststoff bearbeiten. Die Designs der vorgestellten Plotterprojekte von Annett Grosse-Wilde (GroWidesign) stehen als DXF- und SVG-Dateien zum Download für die gängigen Plotter von Brother, Silhouette und Cricut kostenlos zur Verfügung…”
