By functionalizing the surface of a variety of nano-objects (such as nanowires, nanosheets, nanocubes and even biological cells) with polyphenols, researchers at the University of Melbourne in Australia say that they can turn them into superstructured assemblies. The technique, which literally transforms the nanobject into a LEGO brick-like structure with stubs, could be used to […]
Ordinary silicon, the material that has dominated the semiconductor industry for decades, could also make a very promising host material for quantum bits in a future quantum computer. So say researchers at the Delft University of Technology in the Netherlands and the University of Wisconsin at Madison in the US, who have found that electrically […]
The Nobel Prize for Physics 2016 has been divided, one half awarded to David J Thouless, the other half jointly to F Duncan M Haldane and J Michael Kosterlitz “for theoretical discoveries of topological phase transitions and topological phases of matter”. The prize is worth SEK 8m (£629,000) and will be shared by the winners, […]
The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene electronic devices, and could lead to new applications of graphene such as low-power transistors……… http://nanotechweb.org/cws/article/tech/66506 Wrong way: electrons undergoing negative refraction at […]
Researchers in Korea and the UK have discovered that a graphene coating on biological samples helps dissipate the charge build-up that normally occurs on the surface of these samples during non-destructive electron microscopy imaging. Such a charge build-up is usually a big problem in this context and prevents high-resolution images from being obtained…….. http://nanotechweb.org/cws/article/tech/66514 Graphene […]
The 2016 Nobel Prize for Chemistry was awarded to Jean-Pierre Sauvage, Sir J Fraser Stoddart and Bernard L Feringa for the design and synthesis of molecular machines, touted to herald a second industrial revolution. Just as the constant miniaturization of the transistor over recent decades has led to mobile phones and other pocket-sized devices with […]
