Important step in understanding of light scattering

A team of researchers from the University of Twente and from Philips in the Netherlands has succeeded in taking an important step in understanding how light is scattered, absorbed and re-emitted in white light emitting diodes ...

Simplifying supersonic nozzle pressure monitoring

A bit of serendipity while carrying out a routine calibration led a researcher at Lawrence Berkeley National Laboratory's (Berkeley Lab) BELLA Center to discover a new method to measure the pressure of supersonic nozzles. ...

Density-near-zero acoustical metamaterial made in China

When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers ...

The microscopic topography of ink on paper

A team of Finnish scientists has found a new way to examine the ancient art of putting ink to paper in unprecedented 3-D detail. The technique could improve scientists' understanding of how ink sticks to paper and ultimately ...
