3-D printed electrodes free the gas

Alkaline water electrolysis has been touted as a path to establish a hydrogen economy by converting intermittent renewable energies into clean hydrogen-based chemical energy.

A cosmic amethyst in a dying star

On Earth, amethysts can form when gas bubbles in lava cool under the right conditions. In space, a dying star with a mass similar to the Sun is capable of producing a structure on par with the appeal of these beautiful gems.

Ultrafast camera films 3-D movies at 100 billion frames per second

In his quest to bring ever-faster cameras to the world, Caltech's Lihong Wang has developed technology that can reach blistering speeds of 70 trillion frames per second, fast enough to see light travel. Just like the camera ...

Researchers 3-D print tiny multicolor microstructures

Researchers have developed an automated 3-D printing method that can produce multicolor 3-D microstructures using different materials. The new method could be used to make a variety of optical components including optical ...

Bubbling and burping droplets of DNA

Liquid droplets formed from DNA display a peculiar response to enzymes. An international collaboration between LMU and UCSB has now been able to explain the mechanisms behind bubble formation.

Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

Double bubbles pierce with less trouble

Two microscopic bubbles are better than one at penetrating soft materials, concludes a new study by engineers at the University of California, Riverside.
