Yet despite the potential economic benefits, fracking has also generated controversy due to the unknown long-term consequences of all the drilling, pumping, fracturing, and extracting processes involved. Now, two scientists have identified several important scientific challenges encountered in fracking that can be addressed with physical chemistry, which could lead to improved fracking techniques. http://phys.org/news281701080.html Chemistry - Other Tue, 05 Mar 2013 10:50:01 EST news281701080 (Phys.org)—A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules. http://phys.org/news267278467.html Chemistry - Other Wed, 19 Sep 2012 13:01:47 EST news267278467 Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network -- a chemical Google on steroids.

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.

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.
