Physicists from the Max Born Institute in Berlin have now returned to the use of electrons in holography. A special element in their approach is that the electrons that image the object are made from the object itself using a strong laser.
A new method of capturing detailed, three-dimensional images of minute samples of material under extreme pressures is shedding light on the evolution of the Earth's interior. Early results suggest that the early Earth did not have to be entirely molten to separate into the rocky crust and iron-rich core it has today. Researchers at Stanford University and SLAC National Accelerator Laboratory are leading the group pioneering the technique, which could lead to a wide range of new experiments.
In 2009, the journal Nature Physics called it the 'Ionization Surprise'. Where it had been commonly thought that the ionization of atoms by strong laser fields was meanwhile well-understood, novel experiments where rare gas atoms were ionized using relatively long (few-micrometers) wavelength laser light suddenly revealed an unexpected and universal low-energy feature that defied explanation. Now, scientists in Germany provide an explanation.
Die Deutsche Forschungsgemeinschaft foerdert ein Projekt der Fachhochschule Giessen-Friedberg mit 210.000 Euro. Eine von Prof. Dr. Alexander Kloes geleitete Gruppe arbeitet an der 'strukturnahen Modellierung von Nanoscale Multiple-Gate-FETs zur Schaltungssimulation'.
With the aim of confirming that textiles treated with silver nano-particles do not cause any harm, researchers at the Hohenstein Institute in Germany, together with 16 partners from research institutions, industry and the regulatory authorities, are working on a major project to investigate the behaviour, whereabouts and effect of the particles in the environment.
The simulation of laser-based production processes has to cover a wide span of time and length scales, especially in new techniques from micro- and nanophotonics. This requires special algorithms which have already been used successfully at the Fraunhofer Institute for Laser Technology ILT, as well as a massive amount of computer power. Fraunhofer ILT has built a high-performance computer cluster at the Center for Nanophotonics.
Um herauszufinden, wie Fluessigkeiten sich im Kontakt mit nanostrukturierten Oberflaechen verhalten, haben die Wissenschaftler des Exzellenzclusters 'Center of Smart Interfaces' (CSI) der TU Darmstadt ein Nanoanalytiklabor gegruendet.
The U.S. Commerce Department's National Institute of Standards and Technology (NIST) today announced a total of more than $22 million in funding for nine research projects targeting innovative manufacturing technologies in fields ranging from biopharmaceuticals and electronics to renewable energy sources and energy storage.
Together with Italian researchers, ETH Zurich scientists have developed a novel organometallic fuel cell. In addition to generating electrical energy, it also produces fine chemicals from renewable raw materials - with no waste.
