Wrangling flow to quiet cars and aircraft

Plasmas are a soup of charged particles in an electric field, and are normally found in stars and lightning bolts. With the use of high voltage equipment, very small plasmas can be used to manipulate fluid flows. In recent ...

Droplets levitate on a cushion of blue light

Researchers in France have discovered a new way to levitate liquid droplets, which surprisingly also creates a mini light show, with the droplet sparking as it floats above a faint blue glowing gap.

Designing an acoustic diode

Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned by researchers ...

Growing thin films of germanium

Researchers have developed a new technique to produce thin films of germanium crystals—key components for next-generation electronic devices such as advanced large-scale integrated circuits and flexible electronics, which ...

Laboratory breakthrough may lead to improved X-ray spectrometers

Researchers at the Paul Scherrer Institute's Swiss Light Source in Villigen, Switzerland, have developed a new design for X-ray spectrometers that eschews a commonly utilized component to lowers overall production costs and ...
