| Foam favorable for oil extraction: Experiments visualize methods for enhanced recovery from wells Posted: 12 Aug 2014 01:38 PM PDT Researchers demonstrate that foam may be a superior fluid to displace and extract tough-to-reach oil. In tests, foam pumped into an experimental rig that mimicked the flow paths deep underground proved better at removing oil from formations with low permeability than common techniques involving water, gas, surfactants or combinations of the three.  |
| Copper foam turns carbon dioxide into useful chemicals Posted: 12 Aug 2014 01:37 PM PDT Scientists have discovered that copper foam could provide a new way of converting excess carbon dioxide into useful industrial chemicals.  |
| Neutrino detectors could help detect nuclear weapons Posted: 12 Aug 2014 09:16 AM PDT Physicists at the Large Hadron Collider in Switzerland and even in the fictional world of CBS' "The Big Bang Theory" look to subatomic particles called neutrinos to answer the big questions about the universe. Scientists now believe neutrinos could be used to monitor nuclear power plants for signs of nuclear proliferation.  |
| Stinky gases emanating from landfills could transform into clean energy Posted: 12 Aug 2014 09:16 AM PDT A new technique transforming stinky, air-polluting landfill gas could produce the sweet smell of success as it leads to development of a fuel cell generating clean electricity for homes, offices and hospitals, researchers say. The advance would convert methane gas into hydrogen, an efficient, clean form of energy.  |
| Could hemp nanosheets topple graphene for making the ideal supercapacitor?
Posted: 12 Aug 2014 09:15 AM PDT As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors.  |
