Researchers have found a way to reduce the coercivity of nickel ferrite thin films by as much as 80 percent by patterning the surface of the material, opening the door to more energy efficient high-frequency electronics, such as sensors, microwave devices and antennas.
Carbon nanotubes are becoming increasingly attractive for photovoltaic solar cells as a replacement to silicon. Researchers have discovered that controlled placement of the carbon nanotubes into nano-structures produces a huge boost in electronic performance.
Rersearchers have succeeded for the first time to produce uniform antimony nanocrystals. Tested as components of laboratory batteries, these are able to store a large number of both lithium and sodium ions.
Brain sensors and electronic tags that dissolve. Boosting the potential of renewable energy sources. These are examples of the latest research from two pioneering scientists selected as this year's Kavli lecturers at the 247th National Meeting and Exposition of the American Chemical Society.
This report gives an overview of nanomedicine in general with particular emphasis on environmental and human health risks, as well as raising regulatory issues that need to be addressed in order for nanomedicine to deliver on its promises without unduly introducing new risks.
