Tribologie, Korrosion, Konstruktion und Werkstofftechnik sind Wissensbereiche, die sich zunächst parallel entwickelt haben. Das gleiche gilt für die verschiedenen Verfahren der Oberflächentechnik. Heute wird es zunehmend wichtiger, interdisziplinäre Ansätze zu finden, um die Problemstellungen der Zukunft, wie z.B. Umweltschutz oder Ressourcenschonung, gemeinsam zu lösen. Das Buch verfolgt den Ansatz, diese Wissensbereiche zu verknüpfen. Es beginnt mit einer Beschreibung technischer Oberflächen hinsichtlich chemischer Zusammensetzung und geometrischer Struktur. Technische Systeme des Maschinenbaus (Bauteile oder Werkzeuge) sind Umgebungseinflüssen (Druck, Chemie, Temperatur) ausgesetzt, die zu Oberflächenschäden durch Verschleiß und Korrosion führen können. Um Oberflächen davor zu schützen, müssen die Grundlagen der Tribologie (Lehre von Reibung und Verschleiß) und Korrosion zunächst verstanden sein, weshalb die wichtigsten Begriffe und Definitionen zu Beginn des Buches beschrieben werden. Schwerpunkt des Buches ist die Behandlung der Verfahren der Oberflächentechnik, die im Maschinenbau Anwendung finden. Jedes Verfahren wird hinsichtlich Beschichtungsprozess, Anlagentechnik, Schichtwerkstoffen, typischen Schichtdicken, Beschichtungstemperaturen und Schichtwerkstoffen beschrieben und anhand von Anwendungsbeispielen vorgestellt. Wesentliches Element der Oberflächentechnik ist die Kombination unterschiedlicher Werkstoffe oder Werkstoffeigenschaften, um Volumen- und Oberflächeneigenschaften getrennt voneinander entsprechend der Anwendung optimieren zu können. Daher ist abschließend eine sehr kurze Einteilung wichtiger Werkstoffe gegeben (Metalle, Keramiken, Polymere). Die Kombination aus Tribologie, Korrosion, Verfahren der Oberflächentechnik und Werkstoffkunde ermöglicht eine strukturierte Herangehensweise bei der Auslegung von Oberflächen.

There’s no need for expensive, high-tech lab equipment to perform biology experiments—you probably have all you need in your home junk drawer. Use balloons, drinking straws, and empty plastic bottles to construct working models of hearts and lungs. Investigate plant transpiration and photosynthesis with leaves and resealable bags. Build a candy DNA model using gumdrops, toothpicks, and licorice rope. Study capillary action in plant xylem using colored water and paper towels. Extract DNA from a banana using a simple chemical process. Or learn how to turn a smartphone into a photographic microscope. Here are more than 50 great hands-on experiments that can be performed for just pennies . . . or less. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated—seed germination, osmosis, human senses and systems, chromosomes, mitosis and meiosis, and more.

A woman challenges the constraints of life in Prohibition-era Appalachia in this sweeping and richly rewarding novel about endurance, survival, and redemption. The McKenzie women, empowered with a formidable history rooted in the foothills of Appalachia, have passed down their folk-healing wisdom through generations. Rosalee, the last living headstrong daughter in Granny McKenzie’s line, soaked up everything she could about the secrets of the forest before a series of tragedies left her alone, without the protection of the women who came before her. The close-knit ties of Rosalee’s childhood are long gone. Now, at her eastern Kentucky farm, she bears a marriage with a volatile bootlegger. She struggles with the demands of motherhood. And her independence is relegated to its “proper place”: under the thumb of men. Her optimism dimming, Rosalee finds solace in the Kentucky woods, a space that holds secret powers of protection from a life Rosalee can no longer control. To the graves of her female ancestors, beside the waters of an enchanting spring, Rosalee returns time and again to consider her future—and discovers a mysterious connection to her past. As Rosalee wrestles with her isolation, with being a wife in an increasingly dangerous marriage, and with being a woman of her time, she must draw on her strength and resilience to survive—and to protect—on her own terms.
