Using a superfluid atomtronic circuit, physicists have demonstrated a tool that is critical to electronics: hysteresis. This is the first time that hysteresis has been observed in an ultracold atomic gas.
Joint research on super-resolution microscopy from the National Physical Laboratory (NPL) and the University of Cambridge has been selected as a highlight of 2013 by the Journal of Optics, making it freely available to view online.
The Spanish foundation BBVA honors Haider, together with Prof. Harald Rose, senior professor at Ulm University, and Prof. Knut Urban, Forschungszentrum Jülich, for the development of a new generation of so-called aberration-corrected electron microscopes that reach resolutions in the atomic range.
According to Fourier's law, heat spreads evenly throughout a system. For two- and one-dimensional objects such as films or the finest of wires, however, other rules seem to apply. Scientists have now pinned these down.
Molecular physicists from Radboud University Nijmegen have produced images of the changes in direction of colliding nitrogen monoxide molecules (NO) with unprecedented sharpness. By combining a Stark decelerator with advanced imaging techniques, they were able to obtain very high resolution images of the collision processes.
Scientists have discovered that a polymer can provide a key to get into tumors: They have developed a new paradigm to home nanoparticles, containers that measure a few 100 nanometers in size, to endothelial cells.
By varying the geometry of the nanoholes in plasmonic color filters - their diameter, shape, periodicity and pattern - it is possible to control the colors that are transmitted and to create transmit a broad spectrum of colors for imaging applications.
CEA-Leti today announced the launch of PIEZOMAT, a research project funded by the European Commission to design and implement a new technology of fingerprint sensor that enables ultra-high resolution reconstruction of the smallest features of human fingerprints.
Researchers have designed nanoparticles with one half formed of gold branches and the other of silicon oxide. They are a kind of Janus particle, so-called in honour of the Roman god with two faces, which could be used in phototherapy in the future to treat tumours.
Mit Hilfe eines Tricks ist es Physikern aus Kassel und Japan gelungen, die Bewegung von Atomen in Bismut quasi zu filmen und zu manipulieren - ein Zwischenschritt zur Entwicklung ultraschneller Schalter auf atomarer Skala.
