Abstract

Ni-Al-Superlegierungen sind bekannt für ihre guten mechanischen Eigenschaften unter hohen Temperaturen. Die elektrochemische Abscheidung von Ni mit Al-Nanopartikeln in LIGA-Strukturen und folgender Wärmebehandlung bietet die Möglichkeit, Ni-Al Superlegierungen für Hochtemperatur-LIGA-MEMS nutzbar zu machen. Über LIGA abgeschiedene Ni-Al-Mikrozugprüfkörper zeigen in Mikrozug- sowie Mikrokriechversuche eine verbesserte thermische Stabilität gegen plastische Verformung.

Abstract

In the last three decades, research has extensively focused on the role of Fe and other mineral nutrients in regulating biological processes, ranging from the surface to the deep ocean. This has produced major breakthroughs in our understanding of the fundamental role of those bioactive elements on the carbon, nitrogen and sulfur cycles and ecosystem function. However, biological processes cannot be entirely sustained by that small set of chemical elements, and new scientific evidence suggests that trace metals other than Fe (e.g., Co, Mo and Ni) as well as essential organic growth factors (e.g., vitamins) may also be crucial in most aquatic systems.

Abstract

This work considers the behaviour of two nickel-base alloys under thermo-mechanical fatigue loading with varying phase angles between mechanical strain and temperature. The investigations focus on the characterisation of microstructures and damage mechanisms as a function of the phase angle. Based on the results, a life prediction model is proposed.

Abstract

Through evolution of life, animals have adapted to the ubiquitous presence of metals in the biosphere. They utilize the more frequent ones as essential constituents of their biochemical machinery. In fact, about 40% of all proteins present in animal cells are so-called metalloproteins. On the other hand, animals have invented regulatory and detoxifying mechanisms to protect themselves from critical concentrations of both essential and non-essential metal concentrations. Metallomics is a modern approach applying cellular, biochemical, molecular and analytical methods to investigate the relationships of metals in their cellular context. The present edition contains a number of original articles and reviews dealing with various aspects of metallomics in animals, published as Special Issues of the International Journal of Molecular Sciences in 2016 and 2017. The book addresses subjects such as metal definition in biology, metabolism of metals in invertebrate and vertebrate animals, metal detoxification and regulation strategies, supplementation of essential trace elements, metal behavior in pregnancy and embryonic development, as well as metal toxicology and emerging medical implications.

Abstract

Small scale mechanical deformations have gained a significant interest over the past few decades, driven by the advances in integrated circuits and microelectromechanical systems. One of the most powerful and versatile characterization methods is the nanoindentation technique. The capabilities of these depth-sensing instruments have been improved considerably. They can perform experiments in vacuum and at high temperatures, such as in-situ SEM and TEM nanoindenters. This allows researchers to visualize mechanical deformations and dislocations motion in real time. Time-dependent behavior of soft materials has also been studied in recent research works. This Special Issue on ""Small Scale Deformation using Advanced Nanoindentation Techniques""; will provide a forum for researchers from the academic and industrial communities to present advances in the field of small scale contact mechanics. Materials of interest include metals, glass, and ceramics. Manuscripts related to deformations of biomaterials and biological related specimens are also welcome. Topics of interest include, but are not limited to:
