Physiker der Uni Hamburg haben neuartige Magnete, die aus nur wenigen Atomen bestehen, aufgebaut und untersucht. Aehnlich wie bei einem LEGO-Bausatz, allerdings mit viel kleineren Bausteinen, koennen die Wissenschaftler einzelne Eisen-Atome zu unterschiedlichsten Strukturen zusammensetzen.
Engineers at Brown University and QD Vision Inc. have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots are made the same way of the same elements.
A recent paper by Kathleen Eggleson, a research scientist in the Center for Nano Science and Technology (NDnano) at the University of Notre Dame, provides an example of a nanotechnology-related safety and ethics problem that is unfolding right now.
Today, the President's Council of Advisors on Science and Technology (PCAST) released its latest assessment of the National Nanotechnology Initiative (NNI): Report to the President and Congress on the Fourth Assessment of the National Nanotechnology Initiative.
Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have directed the first self-assembly of nanoparticles into device-ready materials. Through a relatively easy and inexpensive technique based on blending nanoparticles with block co-polymer supramolecules, the researchers produced multiple-layers of thin films from highly ordered one-, two- and three-dimensional arrays of gold nanoparticles.
Strong Arm Technologies Inc., made up of students from the Rochester Institute of Technology, beat out more than 120 teams from over 25 colleges and universities across the state to capture the grand prize in the 3rd annual New York State Business Plan Competition, held April 26 at the College of Nanoscale Science and Engineering (CNSE) of the University at Albany.
Engineers at Stanford have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The new technique is simpler, faster and provides greater control than earlier methods and could lead to better batteries, solar cells and catalysts.
Some medicines have to be taken either before, after, or during a meal because food ingredients can affect its absorption or bioavailability. Australian researchers have now encapsulated drugs in a matrix of silicon dioxide and lipids to simulate the administration of pharmaceuticals with food.
In a collaboration with Waseda University in Tokyo, London Centre for Nanotechnology researchers have grown highly boron doped diamond layers only 1nm in thickness, a technique known as d-doping, for the realisation of high performance field effect transistors (FETs).
This outstanding textbook collects on about 1,000 pages the fundamental concepts and key technologies related to advanced electronic materials and devices. The third edition now holds 47 chapters a 20-30 pages, grouped into eight sections.
The Centre for cooperative Research Biomagune will hold a symposium (Safety issues and regulatory challenges of nanomaterials) to analyze the regulatory framework challenges of the European nanotechnology industry on the 3 and 4 of May in Donostia-San Sebastian.
The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences (SEAS).
Thanks to advances in polymer chemistry and a wide variety of monomer constituents to choose from, the world of multiblock polymers is wide open. These polymers can result in an astonishing array of materials, customizable to almost any specification. However, the flood of options could be overwhelming, without a theoretical framework to guide research.
