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.
For his Ph. D. thesis, chemist Thomas Paulöhrl generated various surface structures and three-dimensional frameworks by means of light-induced click strategies. In this way, material can be modified efficiently and with nanometer precision.
The Teoria Research Group at CIC nanoGUNE will research complex liquids and solids by means of molecular dynamics, based on the functional theory of the density. The possible applications of this group's research covers sectors as varied as mining and the computation of biotechnologies and the energy sector.
A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. They have developed an electron pump - a nano-device - which picks these electrons up one at a time and moves them across a barrier, creating a very well-defined electrical current.
The University of Nottingham has begun the search for a new class of injectable materials that will stimulate stem cells to regenerate damaged tissue in degenerative and age related disorders of the bone, muscle and heart.
An interdisciplinary team of researchers led by Jalali and Dino Di Carlo, a UCLA associate professor of bioengineering, with expertise in optics and high-speed electronics, microfluidics, and biotechnology, has developed a high-throughput flow-through optical microscope with the ability to detect rare cells with sensitivity of one part per million in real time.
After more than a decade of research advances, scientists and technologists are learning to measure and manipulate matter to create fundamentally different electronic devices. In a special discussion, three experts recently explored the dynamics making this possible and why these new advances are exciting researchers.
