Dana Filoti of the University of New Hampshire will present thin films of silver and copper she has developed that can kill bacteria and may one day help to cut down on hospital infections. The antimicrobial properties of silver and copper have been known for centuries -- last year, the U.S. Environmental Protection Agency officially registered copper alloys, allowing them to be marketed with the label "kills 99.9% of bacteria within two hours." Copper ions are known to penetrate bacteria and disrupt molecular pathways important for their survival. http://www.physorg.com/news176997558.html Chemistry Mon, 09 Nov 2009 18:30:02 EST news176997558 Archaeologists surveying the world's oldest submerged town have found ceramics dating back to the Final Neolithic. Their discovery suggests that Pavlopetri, off the southern Laconia coast of Greece, was occupied some 5,000 years ago -- at least 1,200 years earlier than originally thought. http://www.physorg.com/news174906146.html Other Sciences Fri, 16 Oct 2009 10:03:06 EST news174906146 (PhysOrg.com) -- A new ceramic material described in this week's issue of the journal Science could help expand the applications for solid oxide fuel cells - devices that generate electricity directly from a wide range of liquid or gaseous fuels without the need to separate hydrogen. http://www.physorg.com/news173626385.html Physics Thu, 01 Oct 2009 14:34:16 EST news173626385 Researchers are developing technologies that use lasers to create arterial stents and longer-lasting medical implants that could be manufactured 10 times faster and also less expensively than is now possible. http://www.physorg.com/news172230934.html Technology Tue, 15 Sep 2009 10:56:49 EST news172230934 Dentists want those expensive crowns to stick to the teeth. But it doesn`t always happen because of contamination during the crown`s bonding. http://www.physorg.com/news167324182.html Medicine & Health Mon, 20 Jul 2009 15:57:31 EST news167324182 (PhysOrg.com) -- A Princeton-led research team has revealed surprising information about how electron behavior influences the conduction of electricity in a class of high-temperature superconductors. An increased understanding of this mechanism could one day transform a number of technologies, including the transmission of electrical power. http://www.physorg.com/news165511195.html Physics Mon, 29 Jun 2009 16:20:36 EST news165511195 Particle filters are standard in the basic fittings for cars. Construction machines, city buses and garbage trucks must now follow suit. This can be achieved effectively and inexpensively thanks to a new material and design for ceramic filters developed by Fraunhofer researchers. http://www.physorg.com/news165150393.html Technology Thu, 25 Jun 2009 17:10:01 EST news165150393 (AP) -- Bits of pottery discovered in a cave in southern China may be evidence of the earliest development of ceramics by ancient people. http://www.physorg.com/news163141367.html Other Sciences Tue, 02 Jun 2009 06:04:10 EST news163141367 (PhysOrg.com) -- Will the legacy of Nobel prize winner Richard Smalley finally be fulfilled? Ever since his pioneering work in the mid 1990's on the synthesis of carbon nanotubes, companies have been struggling to find a commercial application for this amazing material. There was a nanotech "bubble" of start-up companies, none of which managed to successfully IPO due to lack of realizable commercial revenue. Is that about to change? Recent research by Rice University and Unidym indicate that a fully realizable application is finally here for carbon nanotubes. Fortunately, it's in one of the fastest growing display markets, touch screens. http://www.physorg.com/news158587561.html Nanotechnology Fri, 10 Apr 2009 13:06:35 EST news158587561 The legend is that the great rulers of Canaan, the ancient land of Israel, were all men. But a recent dig by Tel Aviv University archaeologists at Tel Beth-Shemesh uncovered possible evidence of a mysterious female ruler. http://www.physorg.com/news158237703.html Other Sciences Mon, 06 Apr 2009 11:55:50 EST news158237703 (PhysOrg.com) -- Electronic products are having to accommodate more and more components, all of which generate heat. Too much heat could put laptops and other devices out of action, so manufacturers equip them with metal plates to discharge it. A new composite can do this better. http://www.physorg.com/news158227207.html Chemistry Mon, 06 Apr 2009 09:01:17 EST news158227207 This story is, literally, stone age meets digital age: University of Washington researchers are combining the ancient art of ceramics and the new technology of 3-D printing. Along the way, they are making 3-D printing dramatically cheaper. http://www.physorg.com/news157730197.html Technology Tue, 31 Mar 2009 14:58:25 EST news157730197 The device looks deceptively simple - a porous clay pot placed in a five-gallon plastic bucket with a spigot - but Vinka Craver believes it can save millions of lives each year. http://www.physorg.com/news156436938.html Technology Mon, 16 Mar 2009 15:43:37 EST news156436938 (PhysOrg.com) -- Engineers at the University of Leicester have invented a new technique in the manufacture of ceramics that has the potential to save the industry time and costs while reducing wastage. http://www.physorg.com/news156160393.html Technology Fri, 13 Mar 2009 10:54:56 EST news156160393 (PhysOrg.com) -- Dwellings in colonies on the moon one day may be built with new, highly durable bricks developed by students from the College of Engineering at Virginia Tech. http://www.physorg.com/news150396734.html Technology Mon, 05 Jan 2009 16:52:14 EST news150396734 Quicker microwave meals that use less energy may soon be possible with new ceramic microwave dishes and, according to the material scientists responsible, this same material could help with organic waste remediation. http://www.physorg.com/news139143291.html Chemistry Thu, 28 Aug 2008 11:54:51 EST news139143291 You may soon be enjoying microwave popcorn and other 'nuked' foods and beverages faster than ever before, while saving on electricity.
