In diesem Abschnitt wenden wir uns Verbindungen zu, bei denen zwischen zwei oder mehreren Metallatomen eine kovalente Bindung diskutiert wird. Bei der Einfuhrung der 18-VE-Regel (Kap. 3.2) wurde bereits die Moglichkeit von Metall-Metall-Bindungen erwahnt.

Publisher Summary This chapter discusses applications of metals on a model traction engine and drinking cans. The most notable part of the traction engine made from copper is the boiler and its fire tubes. In full size, this would have been made from mild steel, and the use of copper in the model is a nice example of how the choice of material can ...

Nitrogen-doped graphene as efficient metal-free electrocatalyst for oxygen reduction in fuel cells.
ACS Nano, 2010Nitrogen-doped graphene (N-graphene) was synthesized by chemical vapor deposition of methane in the presence of ammonia. The resultant N-graphene was demonstrated to act as a metal-free electrode with a much better electrocatalytic activity, long-term ...

Metal–Insulator–Metal Transistors
Advanced Materials, 2008A metal–insulator–metal field‐effect transistor has been fabricated. The device performance was achieved by reducing the density of states by only partially covering the substrate, which increases the relative field effect. An infinite on–off ratio, no lower limit to device dimensions, a generally enhanced flexibility in design, and low production ...

Metal on Metal: Is It Worth the Risk?
The Journal of Arthroplasty, 2010There has been an explosion in the use of metal-on-metal bearings in the last 5 years throughout the world. This has mostly been driven by the use of metal bearings in resurfacing, although metal heads have also been used in conjunction with primary total hip arthroplasties.

Applications of Surface Science, 1982
Abstract The progress of understanding of the epitaxy of metals on metals achieved in the last decade with improved conventional methods and with surface analytical techniques is illustrated with three groups of film substrate pairs: fcc and hcp metals on W and Mo (110) surfaces.

Sealing Technology, 2004
Abstract Process developments over the past 30 years, demanding ultrahigh vacuum, high temperatures and high pressures, have driven the need for advanced technology seals. This article explains how metal-to-metal gaskets have evolved to comply with the most demanding requirements and provide both resilience and low assembly forces.
