Ultrafast sonograms shed new light on rapid phase transitions

An international team of physicists has developed a method for taking ultrafast 'sonograms' that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through ...

Low-noise, chip-based optical wavelength converter demonstrated

(Phys.org)—Researchers from the NIST Center for Nanoscale Science and Technology have demonstrated a low-noise device for changing the wavelength of light using nanofabricated waveguides created on a silicon-based platform ...

Chalk-based coating creates a cooling fabric

In the scorching heat of summer, anyone who spends time outside—athletes, landscapers, kids at the park or beachgoers—could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or transfer ...

Elements in liquid metals compete to win the surface

Some alloys are in the liquid state at or near room temperature. These alloys are usually composed of gallium and indium (elements used in low energy lamps), tin and bismuth (materials used in constructions). The ratio and ...

The perfect angle for e-skin energy storage

Researchers at DGIST have found an inexpensive way to fabricate tiny energy storage devices that can effectively power flexible and wearable skin sensors along with other electronic devices, paving the way towards remote ...
