The new nanomaterial efficiently separates the greenhouse gas carbon dioxide from nitrogen, the other significant component of the waste gas released by coal-fired power stations. This would allow the carbon dioxide to be separated before being stored, rather than released to the atmosphere.
The remarkable material graphene promises a wide range of applications in future electronics that could complement or replace traditional silicon technology. Researchers of the Electronic Properties of Materials Group at the University of Vienna have now paved the way for the integration of graphene into the current silicide based technology.
A breakthrough in our understanding of the properties of titania (titanium dioxide) - the basis of self-cleaning window technology - has been made by scientists at UCL, uncovering a decades old misunderstanding that has clouded our knowledge of how mixed phase titania catalysts operate.
Monolayer graphene exhibits exceptional electronic and mechanical properties, making it a very promising material for nanoelectromechanical devices. Now, researchers have conclusively demonstrated the piezoresistive effect in graphene in a nanoelectromechanical membrane configuration that provides direct electrical readout of pressure to strain transduction.
Forschern ist es gelungen, magnetische Nanokristalle im inneren Hohlraum von Kohlenstoff-Nanoröhren zu züchten. Diese weisen drei Besonderheiten auf: (1) Die Grösse der Kristalle lässt sich durch den Durchmesser der Nanoröhre kontrollieren. (2) Die Kristalle sind vor Oxidation geschützt. (3) Durch ihre Winzigkeit haben die Nanokristalle andere magnetische Eigenschaften.
Researchers have managed to turn the oscillation direction of beams of light - simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical current.
