A new model provides an alternative description of atomic level gold bonding

A study on how gold atoms bond to other atoms using a model that takes into account bonds direction has been carried out by physicist Marie Backman from the University of Helsinki, Finland, and colleagues. These findings are a first step toward better understanding how gold binds to other materials through strong, so-called covalent, bonds.

Nano-Hügel: Wenn statt Löchern Berge wachsen

Ionenstrahlen werden schon lange eingesetzt, um Oberflächen zu verändern. Ionen können dabei so hohe Energien besitzen, dass bereits ein einziges Teilchen drastische Veränderungen auf der damit beschossenen Oberfläche hervorruft. Nach sorgfältigen Untersuchungen konnte das internationale Forschungsteam nun erklären, warum sich dabei manchmal Einschusskrater, in anderen Fällen hingegen Erhebungen bilden.

Diamondoid nanoparticles improve electron emitters

Diamondoids are nanoparticles made of only a handful of carbon atoms, arranged in the same way as in diamond, forming nanometer sized diamond crystals. Researchers have demonstrated the fascinating capability of these tiny little diamonds to act as a monochromator for electrons.

Smart fluids could lead to self-assembling computer chips

Imagine a computer chip that can assemble itself. According to Eric M. Furst, professor of chemical and biomolecular engineering at the University of Delaware, engineers and scientists are closer to making this and other scalable forms of nanotechnology a reality as a result of new milestones in using nanoparticles as building blocks in functional materials.
