Pulsed Laser Ablation of Solids
by Mihai Stafe Aurelian Marcu Niculae N. PuscasThe book introduces 'the state of the art' of pulsed laser ablation and its applications. It is based on recent theoretical and experimental studies. The book reaches from the basics to advanced topics of pulsed laser ablation. Theoretical and experimental fundamental phenomena involved in pulsed laser ablation are discussed with respect to material properties, laser wavelength, fluence and intensity regime of the light absorbed linearly or non-linearly in the target material. The energy absorbed by the electrons leads to atom/molecule excitation, ionization and/or direct chemical bond breaking and is also transferred to the lattice leading to material heating and phase transitions. Experimental non-invasive optical methods for analyzing these phenomena in real time are described. Theoretical models for pulsed laser ablation and phase transitions induced by laser beams and laser-vapour/plasma interaction during the plume expansion above the target are also presented. Calculations of the ablation speed and dimensions of the ablated micro- and nano-structures are performed. The validity and required refinement of different models in different experimental conditions is provided. The pulsed laser deposition process which bases on collecting the ablated particles on a surface is analyzed in terms of efficiency and quality of the deposited films as a function of ambient conditions, target material, laser parameters and substrate characteristics. The interaction between the incident laser and the ablation plasma is analyzed with respect to its influence on the structures of the deposited films and its capacity to generate high harmonics and single attosecond pulses which are highly desirable in pump-probe experiments.

Pulvermetallurgische Fertigungstechnik
by Paul BeissUnter den Oberbegriff Pulvermetallurgie fällt eine große Vielfalt an Verfahren und Produkten, von denen die Strukturwerkstoffe in der Technik die größte Wertschöpfung und Anwendungsbreite haben. Dazu sind sehr unterschiedliche Aufbereitungs- und Formgebungsverfahren entwickelt worden, die auf den Verarbeitungseigenschaften der jeweiligen Pulver beruhen. Eine Auswahl dieser Verfahren mit größerer technischer Bedeutung wird geschildert. Für Pulver, die unter Druck Grünfestigkeit entwickeln, hat das Matrizenpressen bei Raumtemperatur oder wenig erhöhten Temperaturen für die Formgebung von Bauteilen bis etwa fünf Kilogramm Masse mit weitem Abstand die wirtschaftlich größte Bedeutung. Hierzu gibt es zahlreiche Varianten für spezielle geometrische Anforderungen, z. B. Hinterschneidungen, die ausführlicher beschrieben werden. Im gepressten Zustand ist die Grünfestigkeit der Festigkeit von Kreide vergleichbar. Für die technische Anwendung bedarf es einer metallurgischen Konsolidierung durch Sintern, die aus wirtschaftlichen Gründen in schutzgasgefüllten kontinuierlichen Öfen unter Atmosphärendruck abläuft. Die Sinterbedingungen und bei kohlenstoffhaltigen Legierungsstählen die Abkühlbedingungen bestimmen das Gefüge und zusammen mit der Dichte die Festigkeitseigenschaften. Auf diese Prozesse wird detailliert eingegangen. Den Abschluss der Darstellung bildet eine umfangreiche Übersicht über mechanische und thermophysikalische Eigenschaften von Sinterstählen, besonders auch über deren Schwingfestigkeit.

Pump: A Natural History of the Heart
by Bill Schutt"Fascinating . . . Surprising entertainment, combining deep learning with dad jokes . . . [Schutt] is a natural teacher with an easy way with metaphor.&” —The Wall Street Journal A journey into the heartbeat of life on Earth. Millennia ago, when we first began puzzling over the mysteries of the human body, one organ stood out as vital. The heart was warm, it was central, and it moved as it pumped blood. The ancient Egyptians treated it with reverence, mummifying it separately from the body so that the soul inside it could be weighed. Aristotle believed that it was the seat of consciousness. Over the centuries, science has dispelled the myths, but our fascination with the heart has endured. From the origins of circulation, still evident in some microorganisms today, to the enormous hearts of blue whales, we journey with Bill to beaches where horseshoe crabs are being harvested for their life-saving blood, and under the sea to learn about the world&’s most natural antifreeze, flowing through the veins of icefish. And we follow him through human history, too, as scientists hypothesize wrongly and rightly about what is arguably our most important organ, ultimately developing the technologies that have helped us study the heart—and now, in the most cutting-edge labs, the tools that will help us regenerate it. Deeply researched and engagingly told, Pump is a fascinating natural history sure to be loved by readers of Mary Roach and Bill Bryson.
