Using a laser to to study the world at the atomic level

Scientists used their amped-up electron paramagnetic resonance (EPR) spectrometer to study the electron spin of free radicals and nitrogen atoms trapped inside a diamond. The improvement will pull back the veil that shrouds the molecular world, allowing scientists to study tiny molecules at a high resolution.

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.
