In a rapid follow-up to their achievement as the first to demonstrate how an electron's spin can be electrically injected, controlled and detected in silicon, electrical engineers from the University of Delaware and Cambridge NanoTech now show that this quantum property can be transported a marathon distance in the world of microelectronics - through an entire silicon wafer.
The Engineering and Physical Sciences Research Council (EPSRC) has awarded a grant valued at GBP 5m to a consortium of researchers in the UK, led by the University of Surrey, to work on Silicon Photonics.
Researchers at the National Institute of Standards and Technology (NIST) demonstrate a technique that allows them to selectively grow nanowires on sapphire wafers in specific positions and orientations accurately enough to attach contacts and layer other circuit elements, all with conventional lithography techniques.
Dutch researchers have developed a new type of biodegradable nanoparticle. The spherical structures can encapsulate various fat-soluble medicines, which makes it easier to target tumour tissue. These nanoballs are highly promising carriers for the controlled release of anticancer drugs.
