rssFudging in greenhouse gas stats?
08-31-2011
Fluorinated hydrocarbons are potent greenhouse gases, emission of which must be reduced under the Kyoto Protocol. If you rely on the official reports of the participating countries, the output of trifluoromethane (HFC-23) in Western Europe is indeed significantly decreasing. However, ...
Empa researchers use electron beams for chemical reactions
04-14-2011
Electron microscopes use focussed electron beams to make extremely small objects visible. By combining the instrument with a gas-injection system material samples can be manipulated and surface structures measuring only nanometres across can be “written”. Empa researchers, together with ...

Graphene is a promising material for tomorrow’s nanoelectronics devices. Precise and upscaleable methods to fabricate graphene and derived materials with desired electronic properties are however still searched after. To overcome the current limitations, Empa researchers have fabricated ...
Materials for tomorrow's nanoelectronics
07-23-2010
In the recent issue of Nature, scientists from Empa and the Max Planck Institute for Polymer Research report how they have managed for the first time to grow graphene ribbons that are just a few nanometres wide using a simple surface-based chemical method. Graphene ribbons are considered to ...
Process for manufacturing nanoelectronic 'mini-circuits' developed
06-25-2010
Organic semiconductors are very promising candidates as starting materials for the manufacture of cheap, large area and flexible electronic components such as transistors, diodes and sensors on a scale ranging from micro to nano. A condition for success in achieving this goal is the ability ...
Polymer with honeycomb structure
11-25-2009
Graphene consists of a two-dimensional carbon layer in which the carbon atoms are arranged on a hexagonal lattice, resembling a honeycomb. Carbon nanotubes are rolled-up sheets of graphene, and thick piles of graphene sheets form graphite. Graphene boasts some very special characteristics - ...
