The plasma physics of grapes in the microwave
Ever wondered why sparks fly when you microwave two closely spaced grapes? While this simple way of generating a spectacular plasma has intrigued the general public, there has also been a long-running debate about exactly what physics is involved in the process. Dr Kwo Ray Chu and his team at National Taiwan University have recently unraveled the physics behind it. […]

Manufacturing on the nanoscale: Optomechanical sensors with multiphoton polymerization
Sensors are the eyes, ears, and noses of autonomous devices. Whether it’s designed to operate on land, in the air or on ground, any autonomous device needs a huge array of sensors to provide real-time information to maneuver or perform more complex tasks. The challenge is making sensors small and light enough that they do not add bulk to the […]
Probing surface morphology with virtual plasmonic dimers
Nanoparticles exhibit electronic and optical properties that may significantly differ from those of bulk materials or small molecules. By exploiting the optical generation of plasmon dimers of nanoparticles in the vicinity of semiconducting surfaces, Dr Ingo Barke from the University of Rostock, Germany and his collaborators are proposing a new class of ultrasensitive sensors to probe the morphology of surfaces […]
