Die zweite Quantenrevolution: Vom Spuk Im Mikrokosmos Zu Neuen Supertechnologien
by Lars Jaeger„Quantenphysik ist bizarr und komisch, und sie widerspricht komplett unserem gesunden Menschenverstand“ oder ganz einfach „Die spinnen, die Physiker“ - so oder ähnlich ist die Wahrnehmung vieler Menschen, wenn es um die Grundtheorie der modernen Physik geht. Die These dieses Buches lautet: „Quantenphysik, so bizarr und abgehoben sie erscheinen mag, ist für unser heutiges Leben die bedeutendste wissenschaftliche Theorie. Und ihr Einfluss ist bei weitem nicht an irgendein Ende gelangt. Da kommt noch einiges auf uns zu!“ Der Autor steigt dabei mitten in unser Alltagsleben ein: Sie wollen mehr über heutige und zukünftige Technologien erfahren? Dann beschäftigen Sie sich mit dem Quantencomputer oder dem Quanteninternet; Technologien, deren erste Prototypen in den letzten Jahren möglich wurden und schon sehr bald unser tägliches Leben bestimmen werden. Das Buch wird Bewusstsein schaffen für die Bedeutung der Quantenphysik heute, dabei werden auch philosophische und weltanschauliche Fragen nicht außer Acht gelassen. Am Schluss wird der Leser den heutigen Stand der Quantenphysik kennen und dabei Antwort auf Fragen finden, die Einstein, Bohr, Heisenberg und andere Physik-Genies des 20. Jahrhunderts noch nicht wussten. Mit diesem Buch erschließen sich ihm nicht nur eine Reihe ganz neuer Technologien, sondern auch die dramatischen Einflüsse der modernen Physik für das Gefüge unserer Weltanschauung.
Die-Attach Materials for High Temperature Applications in Microelectronics Packaging: Materials, Processes, Equipment, and Reliability
by Kim S. SiowThis book presents the scientific principles, processing conditions, probable failure mechanisms, and a description of reliability performance and equipment required for implementing high-temperature and lead-free die attach materials. In particular, it addresses the use of solder alloys, silver and copper sintering, and transient liquid-phase sintering. While different solder alloys have been used widely in the microelectronics industry, the implementation of sintering silver and transient liquid-phase sintering remains limited to a handful of companies. Hence, the book devotes many chapters to sintering technologies, while simultaneously providing only a cursory coverage of the more widespread techniques employing solder alloys.Addresses the differences between sintering and soldering (the current die-attach technologies), thereby comprehensively addressing principles, methods, and performance of these high-temperature die-attach materials;Emphasizes the industrial perspective, with chapters written by engineers who have hands-on experience using these technologies; Baker Hughes, Bosch and ON Semiconductor, are represented as well as materials suppliers such as Indium;Simultaneously provides the detailed science underlying these technologies by leading academic researchers in the field.

Diesel – eine sachliche Bewertung der aktuellen Debatte: Technische Aspekte und Potenziale zur Emissionsreduzierung (essentials)
by Thomas KochThomas Koch zeigt die Vorteile und Potenziale von Dieselmotoren auf, die seit wenigen Jahren auch in der breiten Öffentlichkeit sehr kontrovers betrachtet werden. Insbesondere werden die technischen Gründe für die Auslegung der Motoren und Abgasnachbehandlungssysteme vorgestellt. Der Autor plädiert für eine strenge, warnt jedoch zugleich vor einer überzogenen weiteren Regulierung der Dieselemissionen. Die neue RDE-Gesetzgebung ist im Grunde die strengste weltweit, da unter unbekannten Fahrbedingungen eine Emissionserfüllung sichergestellt werden muss. Sie sollte daher ausreichend sein. Bei der neuesten Generation von Dieselmotoren kann das NOx-Problem als technisch gelöst betrachtet werden. Daher kann dieser Motor mit seinen positiven Eigenschaften wie geringsten Emissionen, einer hohen Leistung, einem ansprechenden Drehmoment und mittlerweile sehr eindrücklicher Komfortverbesserung weiterhin als zukunftsweisende Technologie betrachtet werden.Der Autor Prof. Dr. sc. techn. Thomas Koch ist Leiter des Instituts für Kolbenmaschinen am Karlsruher Institut für Technologie (KIT) und stellvertretender Vorsitzender der wissenschaftlichen Gesellschaft für Kraftfahrzeug- und Motorentechnik e.V.

Dietary AGEs and Their Role in Health and Disease
by Jaime UribarriOf the many dietary factors associated with inflammation and oxidative stress, a specific group are food-derived pro-inflammatory and pro-oxidant compounds, so-called advanced glycation end products (AGEs).
