Dancing droplets (w/video)

Just as the size of transistors continues to decrease, laboratories are also expected to shrink until they eventually fit on a chip. ETH Zurich researchers have developed a system of using sound waves to move, merge or sort minuscule droplets with reagents or cells in a controlled manner. With ultrasound, represented by curved red and blue lines,...

Designing crack-resistant metals with nanoporous materials

Potential solutions to big problems continue to arise from research that is revealing how materials behave at the smallest scales. The results of a new study to understand the interactions of various metal alloys at the nanometer and atomic scales are likely to aid advances in methods of preventing the failure of systems critical to public and industrial...

3D plasmonic antenna capable of focusing light into few nanometers

Professors Myung-Ki Kim and Yong-Hee Lee of the Physics Department at KAIST and their research teams developed a 3D gap-plasmon antenna which can focus light into a few nanometers wide space. Their research findings were published in ("Squeezing Photons into a Point-Like Space"). Figure 1: 3D Gap-Plasmon Antenna Structure and the Simulation Results....
