Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. http://www.physorg.com/news177572736.html Chemistry Mon, 16 Nov 2009 05:46:54 EST news177572736 (AP) -- Don Ho was right. It is the tiny bubbles. A team of researchers - in Europe not surprisingly - found that Champagne's bursting bubbles not only tickle the nose, they create a mist that wafts the aroma to the drinker. http://www.physorg.com/news173382271.html Chemistry Mon, 28 Sep 2009 18:44:59 EST news173382271 Research by astronomers at the Dublin Institute of Advanced Studies suggests that shadows hold the key to how giant star-forming structures like the famous "Pillars of Creation" take shape. http://www.physorg.com/news159686915.html Space & Earth Thu, 23 Apr 2009 06:29:06 EST news159686915 The National Physical Laboratory (NPL) has developed the first sensor capable of measuring localized ultrasonic cavitation - the implosion of bubbles in a liquid when a high frequency sound wave is applied. The sensor will help hospitals ensure that their instruments are properly disinfected before they are used on patients. The device recently won the annual Outstanding Ultrasonics Product award from the Ultrasonic Industry Association. http://www.physorg.com/news158329042.html Physics Tue, 07 Apr 2009 13:17:47 EST news158329042 Tubeworms have been around for millions of years and the fossil record is rich with their distinctive imprints. But a discovery made by U of C scientists found that what previous researchers had labeled as tubeworms in a formation near Denver, Colorado, are actually 70 million-year-old escape hatches for methane. http://www.physorg.com/news152972257.html Biology Wed, 04 Feb 2009 12:18:08 EST news152972257 (PhysOrg.com) -- The nanobubbles that develop on submerged surfaces should not really be able to exist. Because of the enormous internal pressure, they should disappear within a short time. Nevertheless, they sometimes last for hours: an unexplained phenomenon. http://www.physorg.com/news147454736.html Nanotechnology Tue, 02 Dec 2008 15:38:56 EST news147454736 (PhysOrg.com) -- Scientists are puzzled by the nanobubbles that can develop on surfaces under water. It should be impossible for them to exist but nevertheless they remain intact for hours. They are something of a mystery, yet it is possible to manipulate the development of these bubbles, according to PhD candidate Shangjiong Yang at the University of Twente, Netherlands. The bubbles can then, for example, be used to reduce flow resistance in liquids. Yang received his doctorate from the Faculty of Applied Sciences on 9 October. http://www.physorg.com/news143183890.html Nanotechnology Tue, 14 Oct 2008 06:18:10 EST news143183890 The Douglas-fir, state tree of Oregon, towering king of old-growth forests and one of the tallest tree species on Earth, finally stops growing taller because it just can't pull water any higher, a new study concludes. http://www.physorg.com/news137692385.html Biology Mon, 11 Aug 2008 16:53:05 EST news137692385
