The world's smallest tunnels have a width of a few nanometers only. Researchers from Karlsruhe Institute of Technology (KIT) and Rice University, USA, have dug such tunnels into graphite samples. This will allow structuring of the interior of materials through self-organization in the nanometer range and tailoring of nanoporous graphite for applications in medicine and battery technology.
By carefully controlling the shape of water droplets with an ultraviolet laser, a team of researchers from Australia and France has found a way to coax silica nanoparticles to self-assemble into much more highly uniform silica wires.
There are more than 50 companies in Australia involved in nanotechnology-related business activities. In addition, there are 74 nanotechnology and nanoscience-related research and community organizations. Among universities, there are 19 academic nanotechnology degree programs.
New technologies have sometimes had very harmful effects, but in many cases the early warning signs have been suppressed or ignored. The second volume of Late Lessons from Early Warnings investigates specific cases where danger signals have gone unheeded, in some cases leading to deaths, illness and environmental destruction.
Forscher des Center for Nanointegration (CENIDE) der Universität Duisburg-Essen haben eine Technologie entwickelt, Bewegungen einzelner Atome und Moleküle in Echtzeit nachzuverfolgen. Wer ganz still ist, kann die Bewegung der Moleküle sogar hören.
Researchers from Technische Universität München have developed a new generation of image sensors that are more sensitive to light than the conventional silicon versions, with the added bonus of being simple and cheap to produce. They consist of electrically conductive plastics, which are sprayed on to the sensor surface in an ultra-thin layer.
Researchers at the Aalto University School of Chemical Technology have applied atomic layer deposition (ALD) technique to the synthesis of thermoelectric materials. Converting waste energy into electricity, these materials are a promising means of producing energy cost-effectively and without carbon dioxide emissions in the future.
The strong binding of gold on electronically modified calcium oxide can now be understood in detail. In a computational study, researchers have shown how redox chemistry entirely determines the adsorption strength of gold on the modified oxide where one metal atom is replaced with molybdenum.
