Triboelectric generator captures power from friction

Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us - this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this 'triboelectric' generator could provide alternating current (AC) from activities such as walking.

Tiny bubbles snap carbon nanotubes like twigs

A computer model from Rice University shows that long nanotubes bend and snap like twigs when blasted with ultrasonic energy. The research finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.

Watching DNA unzip real time

Completion of the Human Genome Project in 2003 has revealed all the pieces of the basic code that together make a human being. European researchers with equally ambitious goals have visualised on a single-molecule level the initiation of protein production based on the DNA code of single genes.

Forscher entwickeln neue Methode des Kühlens mit Lichtwellen

Dass Licht entgegen unserer Intuition nicht immer mit Wärme gleichzusetzen ist, macht sich die Quantenphysik bei der Erforschung von Atomen und deren Eigenschaften zunutze. Der Arbeitsgruppe Atomoptik am Institut für Laserphysik der Universität Hamburg ist es nun gelungen, mit Licht Gas-Atome so stark herunter zu kühlen, dass sie sich zu einer Materiewelle zusammenschliessen.
