But that attempt quickly failed, because the dome almost instantly became clogged with frozen methane hydrate. http://phys.org/news253374294.html Chemistry - Other Wed, 11 Apr 2012 15:30:01 EST news253374294 (PhysOrg.com) -- Recently, researchers have been designing a wide variety of self-propelled micromotors, many of which operate using an oxygen-bubble propulsion mechanism that requires a high concentration of hydrogen peroxide fuel. Since hydrogen peroxide is hazardous at high concentrations, this requirement has hindered practical applications, especially biomedical uses. Now in a new study, scientists have designed and built a new type of micromotor that propels itself through acidic environments with hydrogen bubbles, and requires no additional fuels. At extremely low pH levels, the micromotors can travel at speeds of up to 100 body lengths per second, prompting the scientists to call them “microrockets.” http://phys.org/news246090119.html Chemistry - Other Wed, 18 Jan 2012 08:30:01 EST news246090119 An unfortunate consequence of many industrial and manufacturing practices, from textile factories to metalworking operations, is the release of heavy metals in waterways.

Using light as an energy source the team created a photo-catalytic fuel cell that used a titanium dioxide nanotube-array anode and a cathode based on platinum. The light energy degrades the organic material found in the wastewater and in the process generates electrons which pass through the cathode converting it into electricity. The team has published its results on Water Science & Technology. http://phys.org/news232964413.html Chemistry - Other Fri, 19 Aug 2011 09:20:24 EST news232964413 (PhysOrg.com) -- A new approach that organizes previously unused mass spectra from proteomics studies gives scientists the ability to use these spectra to gain more information about proteins in a wide range of organisms. Scientists from the University of California-San Diego and Pacific Northwest National Laboratory have created a vast spectral archive from more than a billion mass spectra acquired at PNNL between 2001 and 2009.

The key advantage of the new solar carbon capture process is that it simultaneously uses the solar visible and solar thermal components, whereas the latter is usually regarded as detrimental due to the degradation that heat causes to photovoltaic materials. However, the new method uses the sun`s heat to convert more solar energy into carbon than either photovoltaic or solar thermal processes alone. http://phys.org/news199005915.html Chemistry - Other Thu, 22 Jul 2010 09:00:01 EST news199005915 A new process for storing and generating hydrogen to run fuel cells in cars has been invented by chemical engineers at Purdue University. http://phys.org/news195903173.html Chemistry - Other Wed, 16 Jun 2010 10:33:45 EST news195903173 Those social drinkers who order super-premium vodka in every martini or vodka-and-cranberry, and disdain that default "well" liquor.
