Highly precise nanostructuring using ultrasound: New procedure to produce porous metals
— 4 Mar 2011 15:00 | TechnologyThey are corrosion resistant, mechanically strong and withstand exceedingly high temperatures. With such characteristics, porous metals are generating a growing interest in numerous…
Clay-armoured bubbles may have formed first protocells
— 7 Feb 2011 15:07 | ChemistryA team of applied physicists at Harvard's School of Engineering and Applied Sciences (SEAS), Princeton, and Brandeis have demonstrated the formation of semipermeable vesicles from inorganic…
NRL scientists develop 3-D model of the ionosphere F-region
— 19 Jan 2011 17:56 | EnvironmentThe first global simulation study of equatorial spread F (ESF) bubble evolution using a comprehensive 3D ionosphere model, SAMI3, has been demonstrated. The model self-consistently…
How do you cut a nanotube? Lots of compression
— 18 Dec 2010 13:36 | TechnologyA pipefitter knows how to make an exact cut on a metal rod. But it's far harder to imagine getting a precise cut on a carbon nanotube, with a diameter 1/50,000th the thickness of a…
Hubble spots a celestial bauble
— 14 Dec 2010 20:18 | AstronomyHubble has spotted a festive bauble of gas in our neighbouring galaxy, the Large Magellanic Cloud. Formed in the aftermath of a supernova explosion that took place four centuries ago,…
TWIPS - sonar inspired by dolphins
— 18 Nov 2010 11:15 | TechnologyScientists at the University of Southampton have developed a new kind of underwater sonar device that can detect objects through bubble clouds that would effectively blind standard…
Getting bubbles out of fuel pumps
— 17 Nov 2010 10:03 | PhysicsFor more than 250 years, researchers have known that under certain conditions vapour bubbles can form in fluids moving swiftly over a surface. These bubbles soon collapse with such…
Astronomers find giant, previously unseen structure in our galaxy
— 10 Nov 2010 15:43 | AstronomyNASA's Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centred in the Milky Way - a finding likened in terms of scale to the discovery of a new continent…
Reservoirs: A neglected source of methane emissions
— 11 Oct 2010 11:00 | EnvironmentSubstantial amounts of the greenhouse gas methane are released not only from large tropical reservoirs but also from run-of-the-river reservoirs in Switzerland, especially in the summer,…
